Along with solar power generators, solar panels are a quiet alternative for keeping your appliances working without lugging around spare gas cans or stopping at the gas station to fuel up for your traditional generator. RV solar panels come in different sizes and wattages for various needs, and you can even buy adjustable ones for paring down or expanding to suit the trip at hand.

What to Consider

Materials and set-up.

The two most common solar panel materials are monocrystalline and polycrystalline. Monocrystalline panels use a single silicon crystal to capture solar energy, while polycrystalline panels rely on multiple silicon crystal fragments. Monocrystalline is more efficient so we only recommend this type.

Solar panels come in rigid and flexible models. This matters when deciding where you are going to use your panels and whether or not you plan on mounting them permanently on top of your RV or camper. Flexible panels are ideal if you’re mounting on a curved or uneven surface, but if your RV is flat up top, a rigid panel will work just fine.

Decide whether you want to mount your panels or go the portable route. Mountable panels come with hardware and instructions for self-installation, like our best overall pick from Renogy . Mountable RV solar panels are more durable than portable ones, fit with waterproofing and wind resistance, since they are always outside braving the elements.

Portable solar panels fold up for compact storage, designed for easy set-up and tear-down from site to site. They are scratch-resistant and can handle a light shower, but they’re not meant to stay outside permanently and will get damaged if you do so. Some portable picks have features like integrated kickstands and handles to make setting them up at the optimal angle as smooth as possible, no matter where you’ve posted up for the night.

Wattage and Efficiency

Most RV and camper rigs require 100 to 500 watts of solar power depending on what you need powered. 100 watts will power a small fridge along with a toaster and coffee maker, but if you have a full on electric stove, a fridge, and multiple appliances, you’ll need more power.

We recommend you start small and expand to more wattage if needed as multiple panels can be wired together for more energy. Keep in mind product descriptions describe watts in optimal conditions—sunny day, no shade, no clouds—and typically pull less than this. The efficiency rate is a better sign of how well the solar panel works—the best ones are 23 percent or higher.

How We Selected

To choose the best RV solar panels, we used our expertise from testing and recommending solar power generators , as well as reviews from other travel outlets like Treehugger and SolarReviews . We considered the different uses for RV solar panels, ultimately presenting a range of options that work for different RV electrical needs. After pooling together the top products, we scoured user reviews to ensure that the quality and efficiency of these solar panels adheres to the performance the manufacturers promise. Here are out top picks for RV solar panels to keep you powered up and on the road.

Renogy Monocrystalline RV Solar Panel Kit

Monocrystalline RV Solar Panel Kit

This kit has almost everything needed for easy installation on any RV or camper. (It doesn’t include a battery, though most kits don’t.) It’s made especially for those who have never installed solar panels, so the components are straightforward and user-friendly. This setup works best for small to medium set-ups like Sprinter vans, camper trailers, and medium-sized RVs.

The two 100-watt solar panels are rigid, but relatively lightweight at 18 pounds, and the included Z brackets and pre-drilled holes on the hardware make mounting easy atop any RV or van.

The included charge controller has LED indicators that let users monitor the status of their Renogy setup. Pro tip: Regulating the amount of energy flowing into the battery reduces the risk of overcharging, overloading, and short-circuiting.

The indicators on these panels also alert you to input changes due to weather conditions like rain, clouds, or nightfall. The aluminum frame panels are UV- and corrosion-resistant to withstand high winds, rain, snow, and blazing heat. For anyone looking to install their first RV solar panels on their own, this kit is an excellent pick.

GoPower Overlander 190W Solar Kit for RVs

Overlander 190W Solar Kit for RVs

This is the largest single 12-volt panel on the market, drawing up to 190W of power to keep any battery charged on long trips, camping, or on the road. All of the mounting hardware and cables needed to connect to your battery are included, making installation easy.

It’s made with an anodized aluminum frame to hold up against weather and durable tempered-glass panels. The panel is on the heavier side at 26 pounds, but packs a lot of power with a wattage of 190.

If you need more power, the company sells an expansion kit that doubles the output. It’s designed for seamless connectivity between your existing solar power system and the panels you want to add for more power.

Customers report easy installation and that the panel maintains power in their RVs even in less-than-ideal conditions like partly cloudy skies and rain.

Renogy Flexible Monocrystalline RV Solar Panel

Flexible Monocrystalline RV Solar Panel

This RV solar panel is great for uneven surfaces like Airstreams and vans, or propped up facing the sun at your campsite. It weighs only four pounds and can withstand high winds, rain, and snow.

It mounts using silicon adhesives for permanent installation , so there’s no need to worry about drilling holes. It can flex up to 248 degrees without any micro-cracks forming, which is handy for hitting the right angle after midday.

Customers like the slim profile of these panels and say the output is great for such lightweight panels. These are best suited for small camper set-ups or as expansions to larger RV solar energy systems, as just one or two of these isn’t enough for a large RV with a lot of appliances.

BLUETTI Monocrystalline Portable Solar Panel PV200

Monocrystalline Portable Solar Panel PV200

This powerful solar panel folds up to a slim 25 by 23 inches and weighs just 16 pounds for easy storage and portability. The integrated kickstand allows you to angle the panel to most efficiently catch sunlight.

It’s designed for durability with a scratch and splash-resistant coating, but it isn’t waterproof and you shouldn’t leave it out in the rain. This portable panel is good for adding power to your RV or camper set-up without taking up a lot of room.

While customers are satisfied with the power output, some notice that ancillary components—like carrying handles and wire straps—aren’t as durable as the panel. Still, the majority of customers report this works as expected and the portability and easy deployment of the panel make this a worthy buy.

Rockpals Monocrystalline Foldable Solar Panel with Kickstand

Monocrystalline Foldable Solar Panel with Kickstand

This Rockpals panel folds up to 17 by 15 inches and weighs only nine pounds, making it the most lightweight option we recommend. That doesn’t mean it isn’t powerful, though, giving you 100 watts of power wherever you need it. It can charge all types of batteries and has the option to deliver power directly to your devices with the integrated USB-C and USB-A ports.

The included cable connection is versatile, with two different-sized DC jacks and an Andersen connector. There’s also a parallel connector cable included if you want to buy another solar panel for a total of 200 watts of power.

Our deputy editor, Zoë Hannah, uses two of these panels to charge up her portable power stations, and while she’s never used them to power an RV, they’re supremely easy to store and set up. The one drawback is the lack of a kickstand—you’d be surprised how much less power you can draw when the panel isn’t angled toward the sun.

Customers also report that service from Rockpals is remarkably helpful with questions or any spare parts you may need.

Jackery Solar Generator 500 with Panel

Solar Generator 500 with Panel

This combo from Jackery includes both the solar panel and a portable power station, so you get an entire power system—one that works in and out of your RV—in one purchase. The generator houses the lithium-ion battery and inverter and is small enough to carry with one hand.

The 100-watt solar panels folds up and includes integrated handles for portability. At 11 pounds, it doesn’t weight down your camper and isn’t too heavy to move and maneuver.

It has a USB-C and USB-A port built into the back, so you can charge small devices by plugging directly into the solar panel without needing extra adapters. The kickstand adjusts to different angles for the optimal amount of direct sunlight.

Solar Panel Buying Guide for RVs and Travel Trailers: What You Need to Know

Whether you're living that mobile, off-grid lifestyle or just want power for the occasional camping trip, solar panels on your RV can keep you powered up and comfortable.

Woman holding solar panel

Interested in outfitting your camper with solar panels? Start here.

In recent years, more people seem to be living and working from the road than ever before, whether it's in a large RV, travel trailer or camper van. To maximize the freedom of such a lifestyle, having a reliable source of electricity is imperative, and few sources are better than the massive ball of fire that rises in the east each morning. 

Adding a solar energy system to your home office on wheels has become markedly easier and cheaper, but there are still plenty of choices, questions and considerations that aren't always so straightforward. We've put together this quick guide with the help of a pair of seasoned pros to determine if solar is right for your ride. 

What are RV solar panels?

RV solar panels work just like residential and commercial solar panels except on a smaller, more transportable scale. Once they're installed on your RV, motor home or camper, solar panels collect sunlight and convert it into usable electricity for your vehicle. In turn, you can use this electricity to power the appliances, lights and sockets in your RV.

Can solar panels save you money?

Interested in understanding the impact solar can have on your home? Enter some basic information below, and we’ll instantly provide a free estimate of your energy savings.

There are a number of reasons to add solar panels to an RV, travel trailer or camper. The most obvious is that traveling around often means spending the night in places where there's no easy access to the electrical grid. The most adventurous among us today manage to live and work full time from the road, making solar all but a requirement. 

"We knew we wanted to go solar to save money, be off grid and live the lifestyle we wanted and live more sustainably," Shari Galiardi told CNET via Zoom from an off-grid campground in British Columbia. 

Galiardi and her partner, Dave Hutchison, have lived and worked full-time from a restored 1957 camper trailer since 2012 with the help of a 300-watt solar system. They told me that while the lifestyle is certainly different from that of the average person, they don't feel as though they're sacrificing very much.

The couple rarely camp places that have power hook-ups, preferring to be off-grid. Hutchison estimated that once in a year they'll plug into an electric outlet at a campsite. 

"Usually, that's because it's all that's available," he said.

Can RVs use residential solar panels?

It is possible to mount regular rectangular rooftop solar panels on an RV, trailer or van. This author has done so twice. However, it isn't the most aerodynamic arrangement.

Considering Solar Panels?

Galiardi and Hutchison use flexible, lightweight panels that can contour to a vehicle's roof and also add less weight to the top of a trailer. There are a number of products that can work with RVs, including portable panels that can be set up on the ground at your destination.

How many RV solar panels do you need? 

Unlike residential and commercial solar systems, which are designed to power an entire home or business, RV solar systems typically deliver a more modest output. This usually isn't an issue, since you don't use as many lights and appliances in your RV as you would in a brick-and-mortar property.

So how many solar panels will you need for an RV? It depends on a few factors, including your energy consumption habits, the efficiency of the panels and the amount of sunshine your home receives each day.

The energy demand of a camper van like this is likely to be met with fewer solar panels than a typical home.

Determining the ideal size and wattage of a mobile solar system works the same way it does in a stationary residential setting. Calculate how much power you'll need during peak usage scenarios and plan your panels accordingly. 

If anything, it should be easier to figure out your requirements, since you'll likely have fewer appliances to consider in an RV. However, an important consideration is the unpredictability of the sunlight your RV will receive while traveling. Unlike a house, your RV's location and orientation will always be changing, so you may want to design your system with this in mind. 

Installing an RV solar panel system

Initially, Galiardi and Hutchison had a friend with experience in the solar industry help them build a small, rudimentary solar system. After a few years, they upgraded their system and even earned a sponsorship deal with a solar panel company.

There are three main  kinds of solar panels for RVs: monocrystalline, polycrystalline and amorphous. 

  • Monocrystalline panels are the most efficient of the three, so they'll generate the most energy in the least amount of time. 
  • Polycrystalline panels are slightly less efficient, but they're a durable and reliable option.
  • Amorphous panels  aren't as efficient as their counterparts, but the thin and bendable construction makes them easy to install and a lighter-weight option.

In addition to solar panels, you'll need several other components to complete your RV solar system, including the following: 

  • Solar inverter , which converts the solar energy from DC to AC power.
  • Charge controller , which protects the storage system from overcharging.
  • Solar battery , which stores the generated energy.

Portable solar panels present another option for RVers.

Because it can be difficult to keep batteries topped up solely by using solar, a backup source of power is also a good idea. Many travelers use some sort of gas or propane generator. Galiardi and Hutchison are equipped to charge up their lithium batteries using their truck while driving. 

"Self heating batteries are fantastic if you're camping in any sort of colder climates," Galiardi says. 

This is typically more of a need with lithium batteries, which can be more efficient, lower maintenance and longer-lasting than flooded lead-acid batteries, but are also more sensitive to cold. 

Finally, a cord to plug into the grid to recharge when it's available is also a must for most. 

RV solar panel maintenance

There's little maintenance to worry about with solar panels. If you're traveling in very dusty or windy conditions, you may need to wipe off or clean your panels to ensure they're working at maximum efficiency.

Traveling may also add a bit more wear to a panel's connectors. Standard solar panel connections are quite weatherproof, but it's worth inspecting your system periodically for signs of deterioration, loose connections or rust. 

It's not recommended to service these parts on your own without the guidance of an experienced electrician. Remember that a panel can be generating energy any time the sun is up, even when it's cloudy, so always treat any connections as live circuits. 

Here Are 23 Ways to Save On Your Electric Bills Right Now

Cost and rebates

The overall cost of your system will depend on factors including the type of panels you choose and how much electricity you need to generate. If you need lots of power, you'll need to buy more equipment, driving up the price.

Galiardi and Hutchison said their 300-watt system with batteries, inverter and other components cost about $3,000, while larger systems for bigger RVs can easily run more than twice as much. 

The good news, according to Galiardi, is that incentives, including the 30% federal tax credit for home solar systems, can apply. 

"It includes second homes. And RVs and boats and off-grid cabins are in that second home realm," Galiardi said.

Are RV solar panels right for you?

It's difficult to argue with the benefits of solar energy, but RV solar panels might not be right for everyone. If you live in your RV and often take it off-grid (where there are no campground hookups), then solar can be a convenient and eco-friendly alternative to gas-powered generators.

Portable and flexible solar panels better suited to RVs may be more expensive than standard rooftop residential panels, but they're still remarkably cheap compared with past eras. 

There's little reason not to boost your freedom by adding a solar system to your rig if you can afford it, though if you use your RV infrequently, it may not be worth the investment.

Hutchison noted that there might be no need for panels if you only ever park your RV at developed campgrounds with provided power.

However, he added it's worthwhile to consider a system with panels and batteries, even "if you plan to spend even one night off-grid between those sites."

RVs have batteries within them that are able to power lights and small appliances, but they won’t last very long. If you want to be able to use things like your microwave and TV, then you’re going to need an external power source. That’s where RV solar panels come in . 

RV solar panels work like a regular home solar system - the solar panels convert sunlight into electricity. Except instead of the solar panels powering your home, they charge your RV batteries. 

You can also get additional batteries that the solar panels can charge, so you have even more electricity available to you when you’re camping. 

An RV solar panel system consists of 4 main components: 

Solar panels to convert sunlight into electricity

A charge controller to prevent your battery from overcharging

An inverter to convert the DC solar electricity into usable AC power

A battery to store the electricity

Do you really need RV solar panels?

While RV solar panels are great, they aren’t necessary. In fact, most RV campers probably don’t need solar panels - if you spend most of your time camping on campgrounds with power hookups, then RV solar panels probably aren’t right for you. 

But, for all of the boondockers out there, RV solar panels are a great, cost-effective investment. Boondocking is when you camp off-grid, outside the amenities of campgrounds, including electricity. In this case, RV solar panels can come in handy. They allow you to keep your batteries charged, and you can charge additional batteries for backup power, as well. 

Also, because the solar panels slowly charge your batteries, they can end up prolonging your RV battery life. Plus, unlike conventional generators that you may use to help power your RV, you don’t have to worry about buying propane for every trip. Once you invest in RV solar panels, there are almost no additional operating costs unless equipment needs to be replaced.

How much do RV solar panels cost?

How much you spend on solar panels for your RV depends on what you need from your solar system. If you use a lot of electricity, you’ll need to purchase more equipment, which will raise the overall price of your RV solar system. 

You can find RV solar panel kits for as little as $100 or upwards of $1,000. It really depends on your energy needs. When you’re just starting out, you can get an RV solar panel starter kit between $200 and $500. 

Kits in this range will usually include a charge controller, solar cables, and one or two solar panels, which is a great jumping-off point when you’re first getting into solar. But, you’ll probably still need a generator to supplement your usage. Once you gauge how the solar panels are working for you, you may need to buy more panels. 

What to consider when buying RV solar panels

There are a few key things to keep in mind when looking to buy solar panels for your RVs. 

Your power consumption

In order to find what solar panels are going to work best for your RV, you need to figure out how much power you consume when you’re camping . Based on that, you’ll be able to determine how many solar panels and any additional batteries you might need. 

Most RV campers use about 20 kilowatt hours (kWh) of electricity a day. The more appliances you have, the higher your electricity usage will be, and thus the more solar panels you will need. 

In most cases, however, two or three solar panels will usually produce enough energy to run most of your small appliances. If you want to run large appliances like a refrigerator or an air conditioner, you’ll need a generator or additional panels and batteries. 

You might not know exactly how much power your RV uses, and that’s okay. You can always purchase a basic RV solar kit and do a test run to see how it meets your needs. Then, you can expand the system to include more panels or batteries if need be. 

System setup

When you get solar panels for your RV, you can use them one of two ways: 

Manually set up portable solar panels

Mount the panels on your roof

For most boondockers, manual setup is relatively easy. You simply lay out your solar panels, connect them to your battery, and face them towards the sun. Then, simply move the panels in the direction of the sun every couple of hours to increase solar production. Keep in mind, however, it is something you have to set up and put away each time you go to a site. 

Roof-mounted RV solar panels are also an option if you don’t want to set up portable solar panels. However, you won’t be able to park your RV in the shade, as the roof will need to be exposed to sunlight. You also won’t be able to turn the panels towards the sun to get a little extra juice. Roof-mounted systems could be slightly more expensive, but their convenience can be beneficial to full-time boondockers. 

Type of solar panels

There are three main types of solar panels : Monocrystalline, polycrystalline, and amorphous panels. Monocrystalline are the most efficient and the most expensive. If you are limited on space, then monocrystalline panels are definitely the panels for you. Polycrystalline panels are slightly less efficient than monocrystalline panels, so they are a little bit cheaper.

Amorphous solar panels are flexible, thin-film solar panels. Although they are the cheapest option, they are the least efficient. This means you would need more of them to produce even close to what the mono or polycrystalline panels produce.  Plus, they must be installed directly onto your RV’s roof using glue, which can cause damage and make them difficult to remove. 

Learn more : Types of solar panels: which one is the best choice?

In our opinion, going with a monocrystalline or polycrystalline panel is the best choice for switching your RV to solar power . However, if you have an RV with a curved roof, like an Airstream, then flexible amorphous solar panels might be the best way for you to have a roof-mounted solar system. 

If you are using solar panels with your RV, you’ll probably want to get some additional battery banks to store your solar energy. Most RVers choose 12v batteries. You can get lead acid batteries or lithium-ion batteries for your RV, but each comes with its own set of pros and cons. 

Lead acid batteries are the most commonly used batteries for RV campers. They’re cheap and durable, which is what makes them so popular. However, they usually need to be replaced after five years, and depending on the type of lead acid battery you choose, it might require regular maintenance. 

Lithium-ion batteries are substantially more expensive than lead acid. However, they last much longer, store more energy, and are more efficient. For people who are boondocking full-time, lithium-ion batteries are worth the extra money. 

But, if you are only using the batteries for a few trips a year, you can get away with a couple of lead-acid batteries. 

Keep your camping trip clean with RV solar panels

As you can tell, there is a lot you need to consider before buying RV solar panels. With limited space and limited power output, it can be difficult to figure out exactly what you need from an RV solar system. 

If  you’re a frequent boondocker, it’s worth it to at least pair your generator with a set of solar panels. The RV solar panel kits we listed are sure to be a great starting point for transitioning to solar energy. 

But why stop at your RV? You can save on energy costs and help the environment by powering your whole home with a residential solar panel system. Our solar panel calculator can tell you how much solar can save you on your specific home! I am running a few minutes late; my previous meeting is running over.

Key takeaways

You can keep your lights on even when you’re off the grid by installing RV solar panels.

RV solar panel systems are made up of solar panels, a charge controller, a battery, and an inverter.

If you normally camp at designated campgrounds, RV solar panels might not be for you. But if you are boondocking off-grid, solar panels can really help improve your trip.

RV solar panels vary in cost, but most starter kits cost between $200 and $500.

When buying RV solar panels you need to consider your power consumption, your system setup, the type of solar panels, and the type of batteries you want to use.

Basics: What are RV solar panels?

RVs are always on the road, constantly exposed to solar radiation. To take advantage of this, RV owners achieve energy independence by installing solar panels on their roofs or carrying portable solar panels for RVs.

RV solar panels can be fixed to the roof of the vehicle with fixed racking designed for them. Since the roof constantly receives solar radiation, RV solar panels can produce high amounts of electricity to power DC and AC loads while on the road or camping.

Having RV solar panels eliminates the need to stop at campgrounds to charge batteries with an external power outlet or the need to use external diesel generators. Solar panels only need exposure to the sun to generate power all day as long as no objects are shading the modules.

Benefits of RV solar panels

RV solar panels can be loyal allies on the road, delivering a great number of benefits. Let’s see some of them:

Simple to no installation

You can install and fix RV solar panels on the roof of your RV, but this is not always necessary. You can opt to have portable solar panels for RVs, which are placed around the vehicle facing the sun. Another option is to stick flexible solar panels for RV to the roof, which does not require drilling holes on the roof.

Portability

RV solar panels will go anywhere with you and will constantly generate power on the road, making them a loyal ally on your adventures. The only thing you need to be aware of is to never park in a shaded spot since your panels would not generate power or will do so at reduced performance.

Independence from the grid and power generators

Regular RVs stop at campgrounds to charge deep cycle batteries. Alternatively, they can use an external generator, but generators produce loud noises and require fuel constantly. RV solar panels are the best solution to these problems, since they only need sunlight to generate power and will work for 20 to 25 years.

What types of solar panels are used for RVs?

You now know the basics of RV solar panels and their major advantages, but can any solar panel do the work? Yes and no.

Some RVs have obstructions like ventilation shafts and other similar objects placed on the roof, limiting the available space for installing solar panels. Other RVs might not have flat roofs, making the installation more challenging.

3 Main Options for Solar Panels: Monocrystalline, Polycrystalline and Thin-Film

To solve these problems, you can use one of the different types of solar panels fitted for RVs. These are the following:

Rigid or Traditional Solar Panels

There are two types of rigid solar panels for RVs: monocrystalline silicon and polycrystalline silicon . They are manufactured using the same source material but have different manufacturing processes and properties.

Monocrystalline Silicon

Monocrystalline silicon is the most powerful and efficient solar technology available for RVs. This technology can be used for homes and RVs, using solar cells manufactured from a single silicon crystal through a process known as the Czochralski process.

Monocrystalline silicon RV solar panels cost around $1.25/W  and the highest recorded efficiency for monocrystalline silicon is set at 25.4% . This technology is a better option if you are looking for a solar system yielding the highest possible power output.

The performance of these modules is affected by a temperature coefficient of nearly -0.38%/ºC . The installation usually requires drilling holes and using a fixing rack for the roof, but they also come in portable designs.

Polycrystalline Silicon

Polycrystalline silicon is created by melting various silicon crystals together, resulting in a solar cell with slightly higher impurities and lower efficiency, but at a much lower cost.

The highest recorded efficiency for polycrystalline silicon is set at 24.4%, while its cost is only $1.00/W , 10% less than monocrystalline silicon. These RV solar panels can be affected by temperature through a temperature coefficient of -0.39%/ºC .

Flexible Solar Panels

Thin-film amorphous silicon.

Amorphous silicon is a type of thin-film technology used since the early 70s. This technology achieved its highest recorded conversion efficiency at 14.0%, but its cost is also low at $0.69/W .

One major point in favor of amorphous silicon RV solar panels is their resistance to high temperatures. They are only affected by a temperature coefficient of -0.234%/ºC . This technology will provide an excellent ally when driving your RV in states with hot climates.

Monocrystalline silicon is not only used for traditional rigid solar panels. This technology was modified and improved in the last decade, to create flexible monocrystalline solar panels. This feature allows modules to be stuck to the roof, without having to drill holes to install racking.

Efficiency values for this type of technology are close to the values of traditional monocrystalline technologies, with efficiencies of 23% to 25%. These flexible solar panels are regularly used for RV rooftop installations and temporal installations at camping sites.  

What is the best type of solar panel for RVs?

Solar panels for RVs differ in aspects like price, conversion efficiency, temperature coefficient, and other factors. In this section we compare each of these:

COMPARING TYPES OF SOLAR PANELS FOR RVS

In the table above you can see major differences between types of solar panels for RVs. As you weigh your needs regarding efficiency, cost, and ease of installation, you might want to choose one or another technology.

Monocrystalline silicon comprises the RV solar panels with the highest power production. These are the best solar panels for RV when you are looking to demand high amounts of energy to live comfortably or want to charge your batteries faster. Polycrystalline silicon also produces a high amount of power while still saving some money. This technology has lower efficiency, but also a lower cost.

Both monocrystalline and polycrystalline silicon can be installed on RV roofs by using a fixing rack or be designed as portable solar panels for RVs. However, monocrystalline silicon technology also has the potential to be designed as flexible modules, adapting its shape to the roof of the RV.

Amorphous silicon is a very unique technology that allows manufacturing solar panels for RVs that adapt to curved roofs, featuring a much lower price per watt and performing better in high temperatures. The downside of this technology is its low efficiency and low power ratings. Amorphous silicon can be used to manufacture portable solar panels for RVs that can even be completely rollable, or also for manufacturing flexible solar panels for roof installations.

Other components in a solar power system on RVs

Solar panels are the major component of RV solar systems, but they are not the only ones. RV requires an off-grid solar system installation to power DC and AC loads.

Connection for an RV Solar Power System

RV solar systems require solar panels, a charge controller, a battery bank, and an inverter. Here you will learn what these components and their functions are:

Charge Controller

The solar charge controller regulates the DC voltage and current sent to the load and the batteries, setting the power output at the right level. This device uses a system known as Maximum Power Point Tracking (MPPT) to optimize the power output from the panels, finding the right voltage and amperage to extract as much power as possible from the system. The charge controller keeps the batteries charged without overcharging them and supplies power to the load as it is demanded.

Battery Bank

The battery bank is where solar energy gets stored for later usage, this is especially practical during harsh climates and nights. This component is comprised of one or several batteries connected to match the input voltage of the inverter and charge controller. Most battery banks are designed to operate at 12V, 24V, or 48V.

The solar inverter is responsible for converting the DC power coming from the charge controller into a modified or pure sine wave with a 120V voltage. This device provides your RV the capacity to power regular appliances like your computer, coffee maker, TV, and many others.

What to consider when choosing RV solar panels? (With expert advice)

Choosing the best solar panels for RV and other components for your vehicle can be challenging. To help you out, in this section we provide you with advice from an expert regarding the aspects to consider when choosing your RV solar panel system and other inputs.

Solar system size: Truly consider your energy needs

RVs do not require as much power as residential solar systems, especially since there are rarely any power-hungry devices like in a house. When spending the day at your RV, you might want to watch TV for a few hours (150W per hour or W/h), turn on your satellite internet (25W/h) for working or surfing the web on your laptop (100W/h), make coffee (1,000W/h), or use other low power consumption tasks.

All of these devices have relatively low power consumption, except for the coffee maker which consumes 1,000W per hour but only operates for 5-10 minutes. Considering and analyzing your power demand habits will help you estimate how much power you need, allowing you to invest in the right size for RV solar panels.

Equation for PV System Sizing

The previous equation can help you to estimate the ideal size for a PV system for your RV. The equation requires you to consider your daily energy requirements, expected Peak Sun Hours (PSH)  or effective hours of power generation at maximum capacity in the location where you will be camping, and a derating factor associated with PV losses. For properly estimating your energy consumption, you can use the widget for reference to obtain the power demand, you just need to figure out the amount of time that you intend to use these appliances.

What is the expected cost of RV solar panels?

RVs can have regular solar systems installed, but they usually go better with RV solar panel kits, which might cost as low as $100 or as high as $3,000, depending on what the kit includes. RV solar panel kits generally include RV solar panels, a charge controller, and wiring accessories,  but some kits can also include a power inverter and batteries, for a premium price of course.

The most simple 100W kit might cost around $100, but a 100W kit with a flexible solar panel might go up to $250. The price increases more and more, depending on the number and quality of the products included in the kit.

What is the best way to mount solar panels on RV roofs?

While portable solar panels do not require to be mounted on a roof since they can be installed on the ground of a camping site, this is not the case for other types of solar panels. To take real advantage of traditional and flexible solar panels for RV, the smart choice is to mount them on the roof of the vehicle. There are different types of mounting systems:

  • Fixed mounting : Fixed mounting solar panels is the most straightforward installation method for rigid or traditional solar panels. This type of mounting requires you to drill holes on the rooftop of your RV and install the mounting brackets to fix the solar panel in place, on a flat position on top of the mounting system.
  • Flexible mounting : Flexible solar panels adapt to the shape of your RV, making them easier to install on any type of RV roof. To install these types of solar panels, you usually have to use VHB tapes or EternaBond tape to set the panels in position. You might also have to drill a hole in your roof to send the cables into the RV, but this installation only requires one hole.  
  • Tilt mounting : Instead of fixing solar panels on a flat position, you could install them with a tilt angle kit. This is a mounting system that includes a tilting platform, allowing you to tilt solar panels in the direction of the sun, depending on your camping location. This type of mounting system makes your RV solar panels absorb more solar radiation and yield a higher power output, especially during the fall or winter season.

Battery size: Amps per hour translate to autonomy

Batteries are an important component of your RV solar system. You might not require much power during the day when you are camping, but you will surely need it at night.

The best way to understand the capacity of batteries is by translating their amp-hour (Ah) capacity into watt-hours, by multiplying amp-hour by the voltage. For instance, a 100Ah battery operating at 24V can store 2,400Wh, more than enough to watch TV for a few hours, turn on your satellite internet, and your computer, and make some coffee during the day.

You should size your solar panel system with enough reserves to fully charge the batteries at least throughout the day. Increasing the days of autonomy (amount of days that you can live off-grid with a single full charge of the battery bank) will also require you to increase the  PV system size. Using the equation shown earlier in this section will help you size correctly your PV system to achieve this objective.

Choosing your charge controller

The charge controller regulates the variable power output of your RV solar panels, making it extremely important for your RV solar system. When choosing a particular charge controller for your RV, the main aspect to consider is matching the voltage input of the charge controller to the voltage output of the string of solar panels. Additionally , you should pick a charge controller that can handle an amperage higher than the total current output of the string of solar panels at your RV.

What is the best type of solar panel for you?

After learning all the benefits of different types of solar panels for RVs, you should now weigh the price, power rating, and efficiency, and consider available space on the roof of your RV against the dimensions of the solar panel. This will help you pick the best solar panels for RV and the ideal configuration for your system.

A gimmick or free electricity on the road? We present you with the best solar panels for RV and answer the ultimate question: Are they worth it at all?

solar panels for travel trailer

When I first saw solar panels slapped on an RV I immediately thought of one of my all-time childhood movies “Race the Sun." It’s about teenagers who build their solar car to race across Australia. 

Now, as a camping and RVing enthusiast, I realize that solar panels can’t power the RV but can make my trip much more convenient and sustainable.

But what sort of problems will solar panels solve in your RV?

Coupled with a capable solar battery, I use them to power the appliances and lighting in my RV. This allows me to camp away from crowded campsites and become fully independent of the grid.

What is more, it allows me to camp sustainably and offset the carbon emissions of my RV by using a renewable source of electricity. 

The 7 Best Solar Panels for an RV or Camper Van (Reviewed by An Electrical Engineer) 

1. renogy 175 watt 12 volt flexible monocrystalline solar panel (best overall).

Wattage: 175 watts | Panel Type: Monocrystalline | Water Resistance: IP67 | Weight: 6.2 lbs

What’s thin as a coin and bends up to 248 degrees? It’s my favorite solar panel for RV on this list. 

The Renogy 175 Watt 12 Volt Monocrystalline Solar Panel has everything I expect from a top-shelf solar panel for RV use. 

It weighs only 6.2 lbs so I confidently fixed six of these to my RV roof. 

What is more, they are extremely flexible, so they’ll adapt to any trailer style. That’s a big consideration for me. 

Scroll down to the Flexible vs. Rigid Solar Panels section to read my opinion, but in short, if you have the budget — go for flex.

Renogy 175 Watt 12 Volt Flexible Monocrystalline Solar Panel product

The Renogy 175W has great solar efficiency thanks to transparent dots on the surface that capture the sun's rays even when coming at an angle. 

In my use, even on a hazy day on Washington state shore, two of these panels provided well over 200 watts. 

  • Extremely flexible
  • Ultra lightweight
  • Resistant to high winds
  • IP68 water and dust resistant
  • Anti-scratch surface
  • Easy to install
  • Mounting eyelets too small
  • Connection leads could be longer

Why Do I Like It?

I glued four of these panels to my RV roof while the remaining two are movable — I use mounting eyelets to rig them on the trailer side that receives the most sunlight.

2. BLUETTI PV200 200W Solar (Runner up)

Wattage: 200 watts | Panel Type: Monocrystalline | Water Resistance: IP65 | Weight: 16.1 lbs

Following excellent solar generators like the AC200P and the beastly EP500 , Bluetti strikes back with a formidable portable solar panel kit that can make a perfect RV solar panel system.  

On a bright su nny day, the Bluetti PV200 200W Solar charges my AC200P solar generator in about 5 hours.

If you’re not big on DIY and mounting stuff, you’d be happy to hear that you can get these up and running in less than 30 seconds.

Unfold, connect, and prop it up.

Now, this can be a deal-breaker to some — there are no mounting eyelets or any other way to fix this panel permanently to your RV roof.

Bluetti PV200

I guess you could glue it with silicone or use  EternaBond tape , but since there’s no rim, you’ll have to cover some of the solar cells as well. 

So why is this solar panel on the list at all?

Because not every camper needs a mini solar power plant on the roof. Most users only need to charge a few gadgets like a laptop, camera, phone, and drone. 

These people use portable solar generators and pair them with portable solar panels, which they prop up on a sunny spot, while their RV stays in the shade.  

  • High-efficiency panel
  • IP65 water and dust resistant
  • Super easy to install 
  • No mounting eyelets
  • Portable use only

Not all places are accessible by RV nor they should be. I can take these solar panels down to the beach and keep the party going.

3. Renogy 100 Watt 12 Volt Flexible Monocrystalline Solar Panel (Best Lightweight)

Wattage: 100 watts | Panel Type: Monocrystalline | Water Resistance: IP67 | Weight: 4.2 lbs

This solar panel for RV is just 0.08 inches thick which is 90% thinner than any rigid solar panel in the 100-watt range. 

The best way to fix this to your RV roof is to use silicone adhesive or EternaBond tape. 

Like on the 175W version, there are six eyelets but they are too small for mounting screws.

So you best use them with rigging cords for non-mobile applications. 

If you want lightweight and reliable RV solar panels that will power your basic devices, you won’t find a better-priced option.

Renogy 100 Watt Flexible Solar Panel

  • Easy to install 
  • 100 watts might not be enough for some users

These solar panels are just 48 x 21 inches which gives me plenty of options to combine and mount them, either along or across the roof axis.

4. Jackery SolarSaga 100W Solar Panel (Most Versatile) 

Wattage: 100 watts | Panel Type: Monocrystalline | Water Resistance: IP65 | Weight: 9.1 lbs

There’s this thing about Jackery products that make them similar to Apple gadgets:

They are reliable, compatible only with other Jackery products, and have an army of loyal customers. 

The Jackery Solar Saga 100W Solar Panel   is beautifully designed, just like every Jackery product. It  folds in half and has two comfortable carrying handles in case I need to deploy them away from my RV. 

Keep in mind that the Solar Saga is a 100% portable solar panel, just like the Renogy PV200. 

This makes it perfect for boondockers who prefer to keep their vehicle in shade and need to power only a few essential gadgets.

A Jackery SolarSaga 100W Solar Panel

I’ve used two Solar Saga 100W solar panels with my  Jackery Explorer 1000  and after 8 hours of charging I could run a mini fridge for 17 hours. 

Unlike the Renogy PV200, this solar panel for RV comes with four mounting eyelets so you can fix it to your RV roof or side.

Unfortunately, these panels are only compatible with Jackery power stations.

  • Super easy to install
  • USB ports for direct device charging
  • Works only with Jackery solar generators
  • Only 4 solar panels can be connected

The Solar Saga 100W comes with USB-A and USB-C cables. In a pinch, I can charge my phone and laptop directly from the panel.

5. Renogy 800W 12V/24V Monocrystalline Solar Premium Kit (Best Premium)

Wattage: 800 watts | Panel Type: Monocrystalline | Water Resistance: IP32 | Weight: 112.8 lbs

Renogy made an offer I could hardly refuse. 

They packed 8 rigid-frame 100-watt monocrystalline panels with the Ro ver 60A charge controller and a Bluetooth module. 

With this kit on your RV roof, you’ll be able to harvest about 3.5-4 kWh of sunlight a day. The panels have a heat-dissipating back sheet that ensures smooth output performance without hotspots.

I was happy to discover that every panel comes with pre-drilled holes in the back frame and Z-brackets for mounting solar panels on the RV roof. When you mount it on the roof, this panel doesn’t go anywhere.

Renogy 800W 12V24V Monocrystalline Solar Premium Kit

But it was the charge controller that sweetened the deal. If you have a large RV and want every convenience of a mobile home, the Rover 60A allows you to slap another 8 solar panels and boost your system to 1.600 watts! 

Using the Renogy DC Home App I can always check what’s going on there, as the controller sends power data directly to my phone via Bluetooth. 

This way I can always tell how much power is produced, how much I use, and even if there’s something wrong with the system. Pro-level baby!

  • 8 x 100W panels
  • Solar charge controller
  • Bluetooth module
  • Automatically detects system voltages
  • Compatible with all kinds of batteries
  • Rigid-frame panels

Apart from making my RV virtually independent from the grid, these solar panels for RV make a great home outage solution. When the power goes out, just move to your RV and continue whatever you were doing.

6. Topsolar Solar Panel Kit 100 Watt 12 Volt Monocrystalline Off Grid System (Best on A Budget)

Wattage: 100 watts | Panel Type: Monocrystalline | Water Resistance: IP65 | Weight: 15.8 lbs

The price of solar gear is dropping, and now you can get decent RV solar panels for less than $150. 

When I saw the price range of the Topsolar Solar Panel Kit I was suspicious at first. Especially since you get  all the cables, Z-brackets, and — listen to this — a 20A charge controller. 

The heart of this system is a rigid-frame monocrystalline solar panel with a waterproof IP65-rated junction box. 

It means your wiring is completely protected from dust particles and low-pressure water jets.

Topsolar Solar Panel Kit 100 Watt

Still, as with all IP65-rated panels here, you don’t want to leave the junction box or connectors in the rain. 

Remember: The panels are weatherproof but the rest of the equipment are not. 

So why isn’t this solar panel for RV on the top of the list? 

First, I wasn’t aware till I tried it that the charge controller it comes with works only with lead acid batteries. Also, the wiring connectors look and feel flimsy, so I don’t know when I’ll need to replace them. 

And, the screws that hold in the charge controller wires are so tiny and so tight that I can hardly unscrew them without stripping them. 

All in all, with a few tweaks this could be a solid and inexpensive RV solar panel for someone getting into the world of solar power. 

  • Very sturdy panel
  • Fast charging
  • Inexpensive
  • Cheap wiring hardware
  • Works only with lead acid batteries
  • Menu button labeled “Mune”

With a more versatile controller and new wiring, the Topsolar 100W solar panel can be an inexpensive building brick for a full-size RV solar system.

7. WindyNation 100 Watt Solar Panel Off-Grid RV Boat Kit (Budget Alternative)

Wattage: 100 watts | Panel Type: Polycrystalline | Water Resistance: N/A| Weight: 19 lbs

The problem with these low-cost RV solar panels is that they often run out of stock. So if you can’t find a good deal on a Topsolar 100W panel, the next best choice in this category is the WindyNation 100 Watt Solar Panel .

This solar panel is even cheaper and comes with a better 30A charge controller, so you can add more solar panels in the future.

The P30L charge controller that is in the box can handle up to 4 x 100W solar panels in a 12V system and up to 8 x 100W panels in a 24V system.

WindyNation 100 Watt Solar Panel Off-Grid RV Boat Kit

On the downside, when my panel arrived, it came without any connectors and mounting hardware. 

I’ve emailed customer service and they sent the missing stuff with no questions asked. 

Still, I had to buy at least two fuse holders and fuses (automotive ATC-type will do) and the 30-amp gauge wires to connect the P30L to my battery bank.

  • 30A charge controller included
  • No water and dust resistance
  • No fuse holders included

If you want to stick a couple of solar panels on your RV roof that will survive whatever weather throws at them and still have enough money for the next 3 road trips, these are the panels for you. Just keep that electric gear tucked inside.

7 Best Solar Generators For RV: Reviews & Buyer’s Guide

What Are RV Solar Panels?

RV solar panels are similar to home solar panels. But instead of powering your home, they use the power of the sun to charge your RV battery. 

When your RV is on the road or parked in a sunny spot, the solar panels on the roof absorb energy from the sun. 

Then you can use the RV battery to power lights and small appliances in your camper.

If you add more batteries that the solar panels can charge, you have more electricity available when camping. 

Do You Need To Use RV-Specific Solar Panels?

Whatever vendors want you to believe, there is no such thing as solar panels that are strictly for RV use. Many companies market their products as RV solar panels but only because those panels are suitable for RV use. 

These include both portable solar panels which have multiple ways of permanent or semi-permanent attaching to your RV roof as well as flexible solar panels that you can fix to curved surfaces. Flexible solar panels are a bigger investment but provide a higher ROI with high-efficiency rates. 

I also want to say that solar panels are not a magic pill. 

Not so Free Energy

This “free” and clean power sounds much better than the fuel generator. 

But when I say free I mean the sunshine. The hardware can be quite expensive. Sure, prices of solar equipment have gotten a bit more reasonable in recent years, but if you want quality, you still need to pay a hefty sum.

You need a couple of pairs of 100-watt panels and deep-cycle solar batteries to store power and charge the controller that keeps them from overcharging. Then there’s the inverter that turns the DC power into AC power that most appliances use.

When you add those up, you can be looking at a $1,500+ investment up front.

Also, collecting solar power is much more complicated than hooking up to shore power at a campsite. You need to know how much power you'll need on a daily basis and size your system accordingly. 

No Shade Where I’m Going

It also means you’ll have to park in full sunshine for most of the day. In other words, you can forget about parking your RV in a nicely shaded campsite where you can throw a barbie and pass a few cold ones. 

Don’t get me wrong, solar power is great and worth the investment, especially if you like to boondock on public land away from the grid. 

It’s just that for the most part, if you want the maximum power, you need to:

  • Open your wallet
  • Leave your rig in the blistering hot sun

Are Solar Panels Worth It? Opinions of An Electrical Engineer

How Much Energy Do You Need for an RV?

First, you need to know how much energy you use in your RV in a day. There are two ways to do this. The first one is easier and the second one is free.

1. Use a battery meter

The easiest way to tell your daily consumption is to install a battery meter like this Renogy 500A Battery Monitor . Before installing solar panels, go camping without hookup charging along the way and the monitor will give you the amount of energy you use with ±1% accuracy. 

2. Calculate your energy use

This way is 100% but requires a bit of math and planning. In short, you need to find out what each appliance or device in your RV consumes and multiply that by the number of hours you expect to use it. 

For example, you have one TV that consumes 100 watts. You guess that you’ll watch TV for about 2 hours per day. So 100W x 2h = 200Wh a day.

You can do the same for every electrical device you want to power while you’re boondocking and you’ll get a rough estimate of the total watt-hours you need. Add a 20% for safety and from there you can estimate how many panels you need. 

If you plan to cook outside and only use electricity for things like lighting, TV, and charging your phone or laptop, two or three 100W solar panels and a 1,200Wh battery will do.

However, if you want to power your fridge or AC you’ll need more panels and batteries. 

How Many Solar Panels Do I Need For My RV?

Now when you’ve measured or calculated the amount of energy you need daily, there is one more thing to consider:

How much energy do solar panels provide to your battery?

You need to achieve a balance here. 

Install too many solar panels without enough battery storage and you're wasting both money and energy that can’t be stored nor used. 

On the other hand, slap one solar panel and a row of batteries, and you won't be able to charge them all while the sun's up. 

Let’s now calculate energy generation and storage needs.

For example, a high-end 100W solar panel will generate an average of 350Wh per day. Keep in mind that this varies by location and time of year. 

You also need to know how many batteries you need to store the power that your RV solar panels generate. One 100Ah 12V battery has about 1,200Wh storage capacity. 

I say it again: Your solar panels for RV will only give you the listed number of watts under perfect conditions.

Perfect conditions = direct sun shining directly at the panel 

On a rainy day, you’ll be lucky to get 100 watt-hours from your 100W solar panels. The same goes for parking in the shade. 

It’s also challenging to estimate the amount of energy you’ll use in a day because days are different. One day you might be outside from dawn to dusk, enjoying nature, hiking, canoeing, and whatnot. The next day might be rainy and you’ll stay inside your RV working on your laptop or watching TV for hours in the evening. 

So whatever you do, estimate high. 

How Much Do RV Solar Panels Cost?

How much your RV solar panel system will cost depends on what you expect from your solar system. Setting up your RV with solar power is not a cheap project. 

On the bright side, there are great solar panels for RV that are available at any price point. 

Weekend RVers — Solar System Around $1,000

If you mainly use your RV over the weekend, you most certainly don’t need a solar system that can power a house. 

In that case, I recommend buying a solar system that will allow you to use the sun to charge phones, turn on the lights, and power a few outlets. 

If you’re not confident about using your RV's original wiring, you can pair your solar panels with a solar generator that already has multiple outlets for both 110V and 12V power. 

Solar generators already have a battery and inverter inside, so you only need to plug in the appropriate solar panels for RV.

Here are a few good combos:

Cost Of Solar Panels: A Walkthrough Guide

Hardcore RVers

If you like to spend several weeks traveling in your RV, I recommend you build a more capable RV solar system. 

Higher-end components are better built which leads to fewer maintenance issues. Manufacturers often offer RV solar panel kits that contain everything you need to build a full-fledged solar system for your RV. 

For example, the Renogy 800W 12V/24V Monocrystalline Solar Premium Kit costs $1,399.99  and includes eight 100-watt solar panels and a Rover 60A MPPT Charge Controller. 

But then you also need an inverter like this Renogy 1000W 12V Pure Sine Wave Inverter for $254.99.

And you need a deep cycle discharge battery. If you want to make the most out of those 3.4 or 4 hours that the sun is directly above, you’ll need at least a 2,000Wh battery. For example, this Renogy 12V 200Ah Lithium Iron Phosphate Battery costs $1,129.

How to Install Solar Panels on Your RV

Now let’s take a look at how to set up RV solar panels in the simplest possible way.

For starters, a solar system for RV has a few basic components:

  • Solar panels for RV
  • Charge controller 
  • Solar battery 
  • Battery monitor with a shunt
  • Fuses and breakers  

And that’s it.  

But how do you hook up solar panels to RV batteries? 

You can’t charge the RV battery with solar panels directly. First, you need to hook solar panels to a charge controller and put a battery monitor in between the controller and the RV battery.  

It might sound complicated but it isn’t. 

Let’s begin with the RV solar panel installation.

Step 1: How to Mount Solar Panels on Your RV Roof

Depending on the kit you bought, you’ll either have to use Z-brackets or screws or silicone adhesive.

If you’re going with screws, mount the brackets and set your panel where you want it, and mark the holes for drilling. 

Now, this part is super important. You’ll be drilling through your RV roof so you don’t want any water to leak inside.

I used a Dicor Roof Sealant . Just apply some sealant over the markings so that when the screw goes in it pulls into that membrane and makes a watertight seal. 

If you're gluing the panels or using the tape make sure the adhesive makes a complete seal around the edges as you don’t want any moisture or dust to accumulate under your flexible solar panels.  

Step 2: How to Connect the Panels

If the wires you got in the solar panel kit are too short, you can use an extra IP65-rated junction box. 

From there, lead the wires into a circuit breaker . I prefer circuit breakers to fuses because I can disconnect the panels from the rest of the system with a flick of a switch. 

RV Solar Panel Installation

Step 3: How to Connect the Battery

Now, remember, you don’t want to hook your panels to the charge controller until you’ve hooked up the battery. 

Connecting the battery is quite simple. You’ll need a fuse in between there, so from the positive side of the charge controller go to the fuse and form there to the positive side of the battery. 

And on the negative side, first, lead a wire from the battery monitor shunt to the charge controller and then from the battery monitor to the negative side of the battery. 

Once you hook up the charge controller to the battery, it’s going to power up the display. From there you can finish hooking up the solar panels to the charge controller and turn on that little breaker. 

And that’s pretty much it. Now you can see what’s coming from solar panels into your battery. 

Rigid vs. Flexible Solar Panels: Which One Is Best for RVs?

Both rigid and flexible solar panels have the same job but they are built for different applications. 

Rigid Solar Panels

Usually have a metal frame and are encased in sturdy glass. This makes them much heavier, but also much more durable.

In the past, rigid solar panels were considered more efficient than their flexible counterparts. However in recent years, technology has advanced, so now they’re an equal match. 

However, two things haven’t changed:

  • The rigid solar panels will take up less square footage than flexible panels.
  • Rigid solar panels are usually less expensive .

Finally, rigid solar panels have a less tendency to overheat. Flexible panels sit directly on the RV roof so there’s nowhere for the heat to escape. Rigid solar panels have raised mounts that allow airflow all around them.

On the downside, the mounts produce more drag on the road, which translates to more fuel spent. 

So to sum up:

  • More durable
  • More efficient (in general)
  • Less expensive
  • Better cooling

Flexible Solar Panels 

Flexible solar panels are much thinner and built like laminate materials so they are bendable to an extent. This makes them perfect for curved or streamlined surfaces like boat hulls, RV roofs, etc. 

Since they are glued or screwed down to the RV roof they don't create any drag while on the road.

Flexible panels also weigh much less, which makes them perfect for RV and marine use. No one wants to put more weight than they already haul around. 

These perks combined make flexible solar panels for RV much easier to install on your rig. In some cases, you won’t need any tools but a tube of silicone adhesive or EternaBond tape. 

Flexible solar panels are also more portable. Removing and storing rigid solar panels is much harder. I’ve never heard of anyone in my RV community doing that. 

On the other hand, you can easily remove flexible panels from your RV roof to slide them into any bay for storage. 

So what do we have so far?

  • Lightweight
  • Fits any surface
  • Easier to mount
  • More portable
  • More expensive
  • More tendency to overheat

Verdict: Rigid vs. Flexible Solar Panels

If you ask me, solar panels for RV have to be either flexible or portable. Rigid solar panels are not just 70% heavier, but also require more complicated mounts, not to mention the additional drag on the road.

Can you run an RV on solar power?

Yes, you can run an RV on solar power. If you need to power just basic RV systems, you can start with solar systems and a battery bank. However, if you want to power the appliances you’d use in your home, you need an inverter to allow you to use a 110-volt system.

What is the hardest part of boondocking in your RV?

The hardest part about boondocking in my RV is water conservation and power conservation. Solar panels can help with the latter.

Can you run an RV air conditioner with solar power?

Yes, you can run RV air conditioners with solar power. But keep in mind that Ac units suck up a lot of power so you’ll need lots of solar panels and a large battery bank.

How many solar panels do I need to run 50 amps in my RV?

You need two 100-watt solar panels to run 50 amps a day in your RV.

Can off-grid solar systems work 24 hours every day?

Yes, off-grid solar systems are designed to work day and night 24/7.

Which is better for the money: RV solar panels or generators?

A generator is always cheaper upfront, but then you have to stop to refuel it, plus you get constant noise and the smell of diesel. RV solar panels are more expensive upfront, but once you clear the bill they keep giving as the power source is 100% free. In addition, you’ll rarely have to do anything about them, while the generators need regular maintenance.

Are RV Solar Panels Worth It?

RV solar panels are definitely worth the investment. 

Some of you will choose an inexpensive RV solar “starter pack” with a simple charge controller and a lead acid battery. 

Enough for charging a few devices between shore hookups.

Or you may want full independence from the grid and splurge on 8x100W flexible solar panels + pure sine inverter and LiFePO4 battery with 3,500+ discharge cycles. 

Others will go for maximum flexibility and rig up portable solar panels for RV and use a solar generator unit that is both an inverter and a battery in one. 

Let’s be honest — in any case, the upfront price is higher than what you’d pay for the fuel generator. 

But once you’re past the price point, everything is pure gain —  both for you and the environment. 

So, let me ask you this:

What price are you willing to pay to ditch the nasty exhaust fumes and harness the clean and free energy of the sun?

Solar Travel Trailers: Guide to Choosing the Best

solar panels for travel trailer

Solar is a relatively new topic. 

After all, at the age of three, my father installed four massive solar panels on my childhood home back in the early 80s. Heck, he was quite progressive! While solar panels are not new themselves, using solar panels on travel trailers is – and it’s changing the way we live and travel.  

A properly designed solar system is not a simple “one and done” solution. I’ve seen countless manufacturers put one or two solar panels on the roof of their RV and call it “solar-powered.” The unfortunate reality is this could not be further from the truth.  

There are so many industry buzzwords floating around that it can be quite challenging to understand what solar means. My goal is to explain what it means to have solar power and what you can expect to gain from a properly designed solar system. After all, how does a solar-powered travel trailer benefit me?  

I’ve broken it down into three straightforward concepts to help understand exactly what solar power does and how it benefits the travel trailer owner’s day-to-day life.

The top three considerations for finding the best solar powered travel trailer while traveling off-grid are:

Location and Size of the Solar System

  • Battery & Inverter System
  • Backup Power Generation

Solar Travel Trailer Charging an Electric Vehicle

As an architect, when designing a solar-powered brick and mortar home, the location and orientation of the solar panels with relation to the sun are critical to maximizing the capture of energy. In the northern hemisphere, a north-facing wall or roof surface will receive very little if any sun exposure at all when the foundation is affixed to the ground.  

While these design features remain true, this is not nearly as important on a solar-powered travel trailer. 

Trailers are constantly moving, and the relative position to the sun depends on the exact position of the trailer at any given moment. Thus, solar panels are typically placed flat on the roof to take advantage of the widest range of solar conditions that you may come in contact with while traveling.  

If you find solar panels on a wall, I encourage you to silently chuckle inside as the designer clearly cares more about how the solar panels “look” rather than how they function. After all, you can’t see solar panels up on a roof of a solar-powered travel trailer.

Solar panels are only effective when the sun is overhead. Solar panels become significantly less efficient when the sun is low in the sky. 

This is called the “angle of incidence.” 

The most effective a solar panel will ever be is when the sun is directly above or perpendicular to the solar panel. Even in the sunniest of environments, the early morning and late evening hours will not provide much solar power. For this reason, we typically calculate an average of 5 hours of sun per day. More sun = more power, simple. One area we can control how much power is captured is to increase the exposed area of solar panels. One simple way to accomplish this is to put as many solar panels as possible upon that horizontal roof surface. When the sun is directly overhead, more solar panels = more electricity generated. To put this into perspective, high draw appliances like microwaves, air-conditioners, and hair dryers use about 1,000 watts of power at any given time. If you have a 1,000-watt solar system, you are supplying around enough power to make one of those appliances run. But what if you have a 2,000-watt system? What happens to all that extra power?  

That’s where batteries come into play.  

If you capture more than you use, the excess is stored in a rechargeable battery system to keep that power to be used at a later time – like, night, for example.  

For a truly solar powered off-grid travel trailer , you will need at least 1,000 watts to accomplish the basic tasks required to stay off-grid for short periods of time. If you’re looking to extend that time to weeks, months, even indefinitely, you’re going to need 2 or 3 times more than that.  

Based on an energy calculator created by Living Vehicle, about 3,000 watts of power is more than enough to run almost all appliances that are required on a day-to-day basis, indefinitely.  

That means you will never need to plug into shore power – as long as the sun is out.  

Battery System

Now that we have all those beautiful solar panels on the roof, capturing power whenever the sun is shining, we need a place to put all that energy. Batteries are a topic in and of itself, and we could talk for days about the size, chemistry, efficiency, etc. For our purposes, I’ll make it simple. I recommend as big of a battery system as you can fit, afford, or otherwise get your hands on. Think of your battery system as you would a gas tank on a motor vehicle. The larger the gas tank, the longer you can go – and the fewer stops you need to make between trips to the gas station.  

Except, in the case of a solar-powered trailer, that gas station is directly above you at all times when the sun is out. It’s a beautiful thing.  

The reason I recommend a large battery system is because the sun does not always shine. I have traveled days, even weeks at a time when I did not see the sun. Not one watt of power entered my energy system from the solar panels. So, I had to rely on the energy stored when the sun was out. The more energy I had, the longer I could go before recharging. Batteries, or energy packs, are measured in how many watts they may store over a period of time. This is measured in kilowatt-hours. In simple terms, if that 1,000-watt array of solar panels is exposed to the sun for one hour, it will store 1,000-watt-hours, or one kilowatt-hour (kWh) of energy. Use this power as you would! But when it’s gone, it’s gone – you must recharge.  

Of course, there are times when the sun just doesn’t come out – winter, for example. I’ve traveled up in the pacific northwest and didn’t see the sun for weeks at a time. There’s only so much energy conservation I was able to do before I simply ran out of power while traveling. This is where backup power generation comes into play.

Living Vehicle Travel Trailer Parked With Sunset

‍Backup Power Generation

Having a backup power supply at the ready is nothing new in the recreational vehicle industry. It’s so common that many luxury RV’s , travel trailers, and campers have a primary source of power – a generator. 

There are all different types of motor-driven electric power generators, but they all do the same thing – make electricity. 

One issue I have with this concept is that manufacturers have relied so heavily on these generators that they have now become the primary source of power when away from shore power. This is a flawed approach, in my opinion. 

Generators are an excellent piece of equipment, supplying high amounts of electricity at the push of a button – but there are downsides to generators too. They are noisy, smelly, and often can’t be used where you’re traveling.  

Many national parks only allow using generators for one or two hours a day. That’s not a great spot to be in if a generator is your primary source of power.

When you combine a solar-powered travel trailer with a generator, the primary source of power becomes the sun. When the sun is out, power is freely flowing (and yes, that was a pun). There’s nothing better than free, clean, and silent power. Of course, the sun does not always shine, and it’s a beautiful thing to have planned for that moment. Backup power generators at the ready, capable machines ready to supply power at a moment’s notice. Now there are other types of backup power generators besides the common gas- or diesel-powered units, and they take all shapes, sizes, and kinds. One of my favorites is leveraging the engine of the tow vehicle. After all – the trailer does not have an engine itself and requires a tow vehicle to move. The installation of a high-voltage alternator in the tow vehicle may quickly and efficiently recharge an entire trailer energy system in a matter of hours.  

It’s a great way to take advantage of what’s already there.   

In the end, solar systems are an excellent addition to solar-powered travel trailers. Properly designed, they allow you to harness the seemingly free and unlimited resource of the sun’s power and go farther than ever before possible. When you are hundreds or even thousands of miles away from the nearest gas station, solar power is available. With enough solar panels, a large enough battery pack, and backup power generation when the sun doesn’t shine, that solar travel trailer can go farther than ever before possible. Now that’s freedom.

RV Solar Panels: A Beginners Guide To Going Solar

Jesse and Lauren Stuart share their tips for using solar panels on your RV.

Jesse and Lauren Stuart

Share this experience

Thinking of installing RV solar panels on your Camper or RV and don't know where to start? From RV solar systems to inverters, and understanding what kind of solar panels are best for an RV, there is a lot to consider when looking to get solar panels for your rig.

So why get RV solar panels installed? Well, RV solar panels are a great way to power your RV when you’re looking to break away from electric hookup sites and try dry camping or boondocking. When you have RV solar panels and a solar system set up in your RV or Camper, you'll be able to power all or some of your RV’s electrical needs like lights, appliances, and even your RV air conditioner.

Whatever size RV you have, before you purchase your RV solar panels, there are a few things you need to know.

RV Solar Panel Systems: Which Is Right For Me?

First, understand when choosing solar panels for your RV or camper, you have two options to consider.

1) The Portable RV Solar Panel System

This system is the easiest to set up and use. These systems typically plug into a dedicated solar plug on your RV and include one or more 100-watt solar panels that can be attached to the roof with Velcro straps. Other portable solar panels come in a suitcase. You connect the panels via a cord and place them in an area that is getting the most sun.

The portable RV solar panel system is a great choice for RVers who are not needing a lot of power, maybe want to keep their lights on, devices charged (i.e phones, computers), and trailer batteries topped off. This typically can be the lowest overall cost to entry, however, you do pay more per watt for the portability of the system.

2) The Permanent RV Solar Panel System

Going the permanent RV solar panel route will be the most expensive of the two options, but this option also happens to be the most efficient . You'll get the best bang for your buck per solar watt, can maximize any unused roof space for panels, the panels will be constantly collecting sunlight (i.e while you're driving), and these won't require setup once you are parked.

Permanent RV solar panel systems are typically installed by professional companies that specialize in RV solar panel installation. These systems are designed for those who are trying to maximize solar to charge not only devices, but appliances like refrigerators, microwaves, coffee makers, and even air conditioners.

How Many Solar Panels Do I Need To Run My RV?

First, you need to determine your RV's power needs. RV solar panels are rated in watts, and you'll need to know the wattage (or watt hours) of all the devices you want to run on solar power - think refrigerator, microwave, phones, TV, etc. Basically, for anything that uses electricity in your RV, you'll need to calculate watt use.

Calculating Watt Use

A quick way to do this is to locate the amps (or watts) on your devices to determine their usage. You need to get everything converted to watts so if a device only has amps multiplied by the volts to get watts.

Example: 120v rice cooker that draws 3 amps. 120 X 3 = 360 watts.

Once you know your watts per device used, you then determine how long you will use it daily and multiply it by that use rate to get its daily watt usage or watt-hours.

Example: Using the above rice cooker for 30 minutes or .5 hours. 360 watts X .5 = 180 watt-hours.

Calculating Number of Solar Panels Needed

Once you have your watt use, you can now calculate the number of RV solar panels and more specifically how many watts of solar you need.

Most people think that a 100-watt solar panel will produce 800-1000 watts of power per day (8-10 hours of daylight). Unfortunately, this is not the case. If you measure this way, you will be setting yourself up for disappointment.

A good conservative rule of thumb is that per 100-watt solar panel you'll collect about 350 watts per day due to things like weather, optimum sun angle/exposure, and panel efficiencies.

Example: You have 1 phone at 5 watts to charge for an hour, you use a rice cooker that uses 360 watts for 30 minutes and you use a blow dryer that uses 1500 watts for 6 minutes.

Phone  5 (watts) x 1 (hour) =  5 watts

Rice Cooker  360 (watts) x .5 (hours) =  180 watts

Blow Dryer  1500 (watts) x .1 (hours) =  150 watts

GRAND TOTAL:

5 (watts) x 180 (watts) x 150 (watts) =  355 watts / day

Given this example, 100 watts of solar panel would be sufficient enough to generate enough power to charge your battery and run your devices each day. As always, please consult with the company installing your panels to determine the panel amount you need.

What Else Do I Need For My RV Solar Panels?

You'll need more than just solar panels for your RV. There are a few more pieces to pick up, such as

Battery Bank

Charge controller.

Batteries store the electricity produced by the solar panel so that your RV can still be powered when there is no sunlight available (i.e. at night or during bad weather). And technically, your solar panels do not power your devices. The solar panels charge your battery and your batteries are what supply the power.

Most batteries are either 24 volt or 12 volt and are usually rated in Amps or Ah. Ideally, you want a battery that has enough capacity to power all your devices/appliances for a couple of days. That way if you have a day of no or low sunlight, you still have some juice to power your devices/appliances.

The quick conversion to find out how much battery you need is watts divided by volts equals amps.

solar panels for travel trailer

An inverter charger converts DC power (produced by solar panels) into AC power that can be used by your RV's electrical system. It also can take AC power and convert it to DC power to charge your batteries.

A good rule of thumb to determine how large of an inverter you may need is to take the total watts you will be using at any given time and multiply it by 1.25.

solar panels for travel trailer

Lastly, you’ll need what is called a charge controller. The main purpose of a charge controller is to create a one-way street for energy. The charge controller takes the energy generated from your solar panels and channels it to your battery bank.

Other benefits of the charge controller are monitoring and stopping potential issues like overcharge or discharge which can ultimately damage your battery.

Is Installing RV Solar Panels Worth It?

That’s a great question and in all honesty very personal to each individual. There is time and money involved when deciding to add a solar panel system to your RV or Camper.

Solar panels are great for those who:

  • Are looking to get a little more off-grid when RVing. Installing solar panels will allow your RV to power up, instead of being connected to campground electric hookups/power.
  • Are looking for a more sustainable solution to sourcing energy
  • Prefer the quiet collection of solar power vs the hum of a gas-powered generator

With a little bit of research, some time, and investment you can truly open up the possibilities of where you can go RVing.

RV Solar panel costs

Generally, a complete RV solar panel system will cost between $600-$2000, including the solar panel itself, installation, and any custom electrical work needed for the panel to work correctly. Costs vary widely depending on the type of use for your RV, from weekend outings to extended multi-day trips.

The basics of an RV solar panel setup

Solar panels for RVing and motorhomes work the same way a residential solar installation operates: solar panels capture sunlight and convert it into electricity, and you can use that solar electricity to power appliances. You can buy specialized portable solar panels designed for easy setup and take down, as well as small or flexible panels designed for mounting on an RV roof.

If you spend time camping and traveling in an RV, a solar panel setup can be a cost-effective, environmentally friendly, and convenient way to produce electricity on the go. Solar panel systems generally require little to no maintenance and provide a dependable source of electricity when the sun is shining. For RVers who mostly stick to campgrounds with electrical hookups, however, RV solar panels likely won't provide enough extra benefit to rationalize spending money on them.

Determining factors: What to consider when buying an RV solar panel system

A critical difference between residential and RV panels is the size of the system: RV solar panel setups are usually designed to provide enough power to recharge small devices or a few larger kitchen appliances. In contrast, a home solar system is typically sized to cover most or all of your property's electricity needs. You can always add more panels to your RV solar setup. Still, given the small amount of roof space and energy storage capacity requirements, RV solar panel systems are generally on the smaller side than residential rooftop installations. Many solar panels are made from monocrystalline cells, which are more efficient than polycrystalline cells. Below we have laid out some groundwork to determine how big a system you need.

How many solar panels do you need to run an RV?

Most solar panels for RVs are between 100 and 400 watts of power; an RV needs about 120 watts of energy on average. This means that an RV will need three 400, ten 200 solar panels, or any other combination of power outputs to meet its typical energy demand of 120 watts. What can you power with that kind of solar panel setup for your RV? For the following examples, we'll assume that your RV solar panel setup is sized at 800 watts and you have an appropriate storage setup to take full advantage of the energy your panels produce.

How many solar panels do you need for common appliances?

What do these numbers mean? Looking at column four, you can see an example of how much energy in watt-hours (Wh) running each appliance for an average amount of time in a day might use. If you have an 800 W RV solar panel system in direct sunlight for 5 hours daily, you'll produce approximately 4,000 Wh of energy each day (5 x 800 = 4,000). According to our calculations in the table above, that's more than enough to power small devices like lights and TVs, but you won't be able to run a refrigerator for an entire day.

An important takeaway from this analysis is that while solar panel systems for RVs will be able to power most of your small electronics and keep the lights on, don't expect to be able to run an unlimited amount of appliances. RV solar panels are a great way to keep the essentials up and running, but they likely can't power energy-hungry devices for too long.

Each RV owner has different reasons for going solar, which can affect the system setup they choose to implement. A roof-mounted RV solar system is an option if you don't want to set up portable solar panels every time you use your RV, making it the more convenient option for someone who uses their RV often. Another option is to use portable solar panels; this option is less expensive but requires more repeated setup and breakdown. With portable solar panels, you also don't have to worry about always having to park in direct sun for energy production. All you need is a battery and open space.

Dive into our complete overview of portable solar panels to learn more.

How do solar panels work for campers, RVs, and motorhomes?

To generate solar power for your RV or camper, you'll need a setup complete with the following components:

Solar panels

A charge controller to prevent overcharging your storage system

Solar batteries to store energy (options are lead acid or lithium-ion )

An inverter to convert direct current (DC) electricity to alternating current (AC) electricity (Occasionally pre-built into the solar battery) and possibly a battery monitor

You can buy all of these components separately, but some motorhome solar panel kits are available to purchase that include most components. For example, WindyNation makes a 100-watt (W) RV solar panel kit with a solar panel, solar charge controller, cables, battery chargers, fuses, and mounting hardware. You'll need to purchase a battery separately for this specific kit.

You'll also need proper wires and cables to hook all of your components together and racking and mounting equipment for your panels – these parts will be included with your solar panel or battery system purchase. Remember that some equipment, such as pwm charge controllers, aren't weather-resistant and must be installed somewhere safe.

Do you need batteries for your RV solar panels?

A deep cycle battery for your RV solar system is essential for running appliances outside daylight hours or when it is cloudy. Since RV solar panels are not grid-tied, your battery bank is your principal backup energy source. RV batteries will store energy produced by your PV panels, allowing you to use it as needed, while a charge controller will regulate that energy and prolong battery life. The real question is: what kind of batteries are best for your RV system?

Gel batteries

Unlike standard lead-acid batteries, gel batteries are sealed. These batteries do not need to be monitored, and they don't produce any gas, making them an excellent choice for installing and then, more or less, forgetting them. Another benefit of gel batteries unique to RV solar systems is that they can be installed in many positions and orientations, making them an attractive option if space is an issue. Gel batteries are used in many motorized scooters and wheelchairs for their versatility and safety.

The caveat with gel batteries — which applies less to RVs — is that they don't have the same capacity as other rechargeable batteries. They can't meet the energy demands of a household the same way other options can, but this may not be an issue for an RV with lower energy demands.

Lithium-ion batteries

While gel batteries provide more flexibility and a "set it and forget it" setup, lithium-ion (Li-ion) batteries are often the best choice, offering higher energy densities than any other type of battery charging currently available. Because lithium batteries have higher capacities, they can store and discharge more energy than other types of batteries with more amp hours of power. They're also typically more efficient and last longer, often making them the best option for RV solar systems.

However, one drawback is particularly applicable to those who use these batteries for their RV solar panels: Li-ion batteries (typically 12 volts) can overheat and become damaged at higher voltages. You'll want to keep your Li-ion battery in a cool location out of direct sunlight. Li-ion batteries are also typically priced higher than alternative energy storage options, so you'll want to protect them.

Absorbed glass mat batteries

Absorbed glass mat (AGM) batteries are a relatively new battery available on the market, and they are a good choice as an RV solar battery. These deep-cycle batteries are sealed, making them a maintenance-free choice for RV owners. Like gel batteries, AGM batteries would struggle to meet the energy demands of a household. But, the lower needs of an RV make them a good choice, and compared to other battery options for RVs, the upfront cost is relatively low.

However, AGM batteries can be more expensive compared to lead-based batteries, making them a less attractive option in some cases. Overcharging can also ruin them, and they aren't as efficient as Li-ion battery options. With AGM batteries, RV owners must ensure their charge controller remains in good working order. MPPT controllers can also be used if you have a high enough voltage.

Should you install solar panels on your RV?

If you're the type of RV owner who plans on spending lots of time in remote locations and dry camps without power hookups (known as "boondocking"), solar energy may be a way to see how much power you can generate and some long-term savings when compared to a gas generator. Over time, the costs of continually starting and running a gas generator will exceed the investment required for a solar panel system. You can expect your solar "payback period" to be under five years, but the time it takes to recoup your investment will depend on the equipment you purchase and the amount of sunlight that hits your solar panels.

However, RV solar panels won't make financial or practical sense for every RV owner. If you spend most of your RV time at campgrounds, you're probably better off hooking up to the local power system and paying the associated fee. Installing solar may save you money, but you may have to wait a long time to break even. Additionally, if you only take RV trips a few times per year, the upfront cost of an RV solar panel setup will likely not be worth the few times you can use the system. You should also check if the solar panel has a warranty available, just in case anything goes wrong with your system and needs replacement.

RV solar panel setups are often do-it-yourself (DIY) projects. Check out our video on DIY solar to see if it's right for you:

Frequently asked questions about RV solar panels

How many solar panels do i need to run an rv.

This depends on the wattage of the solar panel or panels that you have. For example, a 100-watt solar panel is enough to be a power source for smaller appliances and devices, such as lights or chargers, but you would likely need more than one panel for larger appliances or to power things full-time. Depending on your energy needs, you may need a higher-watt solar panel or need to install at least two.

Which type of solar panel is best for RVs?

Portable solar power systems or flexible solar panels are ideal for RVs. They are smaller, easier to install, sometimes foldable, and cost-effective compared to ground-mount or rooftop solar panels.

How much is a solar kit for RVs?

This largely depends on what you get, but you should expect to pay between $300-$400 for a solar panel system for an RV. It is best to shop around and compare solar systems online.

Can you run an RV air conditioner with solar power?

You can, but not with one 100-watt panel.

Modern RV air conditioners typically require 500-900 watts every hour. So, while you certainly can run your RV air conditioner on solar power , you'll need more than one panel.

Do I need an inverter to convert DC to AC with RV solar panels?

Like with your home, the appliances inside an RV run on AC while the engine and battery of the RV use DC electricity. Solar panels run on a DC, meaning that just like a residential solar setup, your RV solar panel system needs an inverter to convert that energy to AC electricity. 

Installing solar panels on your property leads to savings

As an RV owner, you can save money by installing an RV solar panel system, but you'll reap more savings when you install a ground-mounted or rooftop system on your permanent property. To better understand your options for installation, check out EnergySage's Marketplace , where you can register your property and receive multiple solar quotes from local, pre-screened solar installers.

Things to Consider Before Buying Solar Panels and Kits for RVs

RV-ready solar panels are starting to provide campers with more options than ever – but that means you’ve got to do your research before picking any set of panels. If you’re looking to take your RV solar and make it environmentally-friendly, make sure to keep these details top of mind.

Types of Solar Panels and Kits for RVs

Monocrystalline solar panels.

Monocrystalline solar panels are the top tier of RV panels. As the most popular kind of panel, they’re also the most efficient – which means you’ll get a higher output and potentially be able to produce more power, even when sunlight is limited. These panels are made from one large silicon crystal. However, they tend to be the most expensive pick. 

Polycrystalline solar panels

Polycrystalline solar panels are made out of multiple small solar crystals, along with silicon. This makes them more affordable than monocrystalline panels, but they do produce a small amount less—about 1 percent—power in comparison. They’re very common, thanks to their more budget-friendly cost, though these panels are a little less energy-efficient. 

Amorphous solar panels

If you’re looking for the cheapest option, amorphous solar panels are the way to go. These very thin film panels are made out of silicon, and they’re the most inexpensive pick you can buy. However, they also have the lowest power output of all three kinds of solar panels. Additionally, because they tend to be larger in size, they can require double (or even triple) the roof space of a polycrystalline or monocrystalline panel on your RV’s roof. You’ll also need more amorphous solar panels to collect the same amount of power as the other kinds of panels.

Key Features of Solar Panels and Kits for RVs

Solar batteries.

Getting solar panels alone won’t enable you to use the sun’s rays to power your RV’s electrical appliances. You’ll also need a solar battery, or a few solar batteries, to be able to store all of the energy your solar panels capture. So, it’s a smart move to look for solar panel kits that include solar batteries to simplify your installation process. Commonly, solar batteries are either lead acid or lithium-ion, and these both will allow you to keep running your electric items even when the sun sets with all of your stored power.

Charge controller and inverter

In addition to ensuring your solar setup comes with a place to stash all of the energy you collect, you’ll also want to make sure that it includes a charge controller and inverter. These two must-have components are key for managing the electrical current within your RV, and they properly direct and convert the solar energy you collect so it’s useable and able to power different gadgets. The charge controller helps prevent overcharging your energy storage system. The inverter, on the other hand, converts DC current to AC current that’ll work with everything from your TV to your RV’s fridge.

The ability to add more panels

Lastly, you want an adaptable and flexible solar panel kit for your RV. You might start out with just one or two panels, but quickly find that you need more to power demanding appliances like your fridge. Or, you might opt for single panels that can be customized. However you set up your solar panel system, it’s important to choose an option that allows you to add panels as needed in the future. After all, your needs can change; you might even find that when you’re camping outdoors for longer periods, you want the ability to store even more power.

Solar Panels and Kits for RVs Pricing 

Solar panel kits for RVs start at around $500. For between $500 and $1,000, you’ll be able to find reasonably priced kits that include one to three solar panels, plus accessories like installation and mounting hardware or wiring. Additionally, you can find panels alone within this price range. If you’re looking for a comprehensive solution, one that includes panels as well as in-RV control panels, all of the wiring and electrical gear you’ll need, and mounting accessories, you can expect to spend anywhere from $2,000 to $6,000. The more extensive your RV solar panel setup, the more you’ll need to invest (especially if you’re looking for a lot of power).

You’ve got questions. The Drive has answers.

Q: How many solar panels do I need to run an RV?

A: Typically, an RV needs anywhere from two to four 200-watt solar panels to handle all of its energy consumption. If your power needs are more significant, you may need additional panels. 

Q: What will a 100-watt solar panel run in an RV?

A: 100-watt solar panels are best for light power consumption. A single panel can typically recharge electronic devices, like laptops and smartphones. It’ll also power low-energy devices like ceiling fans and LED light bulbs.

Q: What will a 200-watt solar panel run in an RV?

A: With a single 200-watt panel, you’ll have enough power to keep a 12-volt refrigerator running. If your panel is paired with a battery bank that saves extra power, you may also generate enough to run small appliances, like a coffee maker, for short periods of time. 

Q: Can you run an RV air conditioner with solar power?

A: With a suitable system – enough solar panels – you can absolutely run your air conditioner on solar. You simply may need more panels than the typical RV owner to handle the load, and you may need to upgrade or make some tweaks to your RV’s electrical system.

RV Solar Panel Buyer’s Guide

best-rv-solar-kit

Certain factors will have an impact on which RV solar panels fit your needs. This section will discuss each of them to ensure you’re capable of making a responsible buying decision. As a result, this entire process should go much smoother than you initially anticipated.

One of the first things to think about when buying solar panels for RVs is their efficiency. This factor will determine how much sunshine the device can turn into usable electricity. In other words, the higher your panel’s efficiency, the more energy it’ll produce.

Most panels will have an efficiency rating of about 15%, which is the standard for functional options. But the best solar panels can have it rise well above 20%. You’ll need to take your onboard appliances’ expected power consumption into account. It’ll ensure making a decision about what efficiency rating works best isn’t a difficult choice.

Size Measurements

In most cases, RV solar panels will be installed on your rig’s roof because of its exposure to those crucial sunrays. This location means RVers need to think about panel size before choosing their ideal solar panels.

Finding the panels with appropriate measurements will optimize your roof’s available space. I’d suggest using your roof’s dimensions as a resource to ensure you’re getting devices suitable for your situation.

It’s also worth noting that solar panels will have to share roof space with other hardware, such as an air conditioner or antenna. You’ll need to think about these pieces of equipment when making this decision, as well.

Construction

Picking the right solar panel is only half the battle, considering you’ll need to install them to provide your rig with usable power. This process can prove tedious without a panel with lightweight construction.

As a result, I’d suggest looking for panels on the lighter side to ensure this installation isn’t a burdensome process. But please, make sure these lightweight options are still sturdy and reliable. Some brands will only focus on making their products weigh less rather than making sure they remain durable.

These lightweight panels will also keep your rig’s chassis from becoming overloaded. It’s just a simple way to ensure your new devices don’t cause more headaches than solutions.

As most RVers know, energy stored inside your batteries is accessible in two different ways. Devices built to operate on 12v DC current can access it directly. But most appliances will require 110V DC power, which has a different process of obtaining this stored energy.

Converting the current in your batteries into AC will require an inverter. These devices are necessary for anyone looking to run AC appliances onboard RVs. Most solar panel kits will come with an accompanying inverter to make this process easier.

The first thing to know about inverters is they’re rated in watt output. For example, a 1500 watt inverter can operate most small appliances that require 10amps AC current. These appliances include TVs, coffee makers, computers, interior lights, and radios.

If you need solar power for RV air conditioner units and vacuums, buying kits with a higher wattage inverter will be necessary. A 3000w inverter would be an ideal choice as it creates a maximum available power of 30amps AC currents. It should power these appliances with ease.

You should also note that these inverters have to pair with an appropriately sized battery bank. If they’re not, the batteries will discharge too quickly. Choosing the right size inverter will depend on the max draw on your batteries, which means thinking about how many appliances you intend on powering at once.

Solar Charge Controllers

Another standard inclusion inside the best solar panel kits will be solar battery charge controllers . I’d suggest making sure these controllers are waterproof before deciding on what kit to purchase. This feature will ensure camping out in the open won’t be overly complicated.

You’ll also have to think about the solar charge controller’s amp power output rating. In most cases, a 400 watt rig solar system will come with 30-35 amp controllers, which should have no issues handling moderate power needs.

But some rig owners consume more energy, and these smaller charge controllers won’t fit their needs. In this case, you’ll require a larger solar array of an 800-watt solar system and a larger 60-80 amp charge controller.

If you use a charge controller that’s too small, it’ll bottleneck the power output of your rig’s solar panels. For instance, 35-amp solar panels paired with a 20-amp controller will only be a waste of potential charging power. It ends up not being a very efficient setup.

Your Rig’s Battery

Rig owners looking to use a solar power system will need a deep cycle battery inside their RV . These deep cycle batteries can store the generated power from your solar panels for later usage down the road.

You should also know that solar panels are capable of working with either 12V or 24V RV batteries. Most rigs will have two 6V batteries wired in a series or one 12V battery. The capacity of your particular battery bank is measured in what we call Amp hours (Ah). For example, 100Ah batteries can produce 100 amps per hour or 1 amp pet 100 hours.

A rig’s solar panels should produce enough energy to recharge your RV’s batteries, which will always keep them at or above a safe level. This ability is essential because a battery that’s fully discharged regularly can suffer permanent damage and provide lesser performance.

RVers who keep using more energy than their solar panels can produce will end up depleting their batteries. This issue could be solved by giving them a boost from gaining access to shore power or using a generator.

But the best way to avoid this problem is by estimating your maximum energy usage on a given day by adding all your intended appliances’ amp hours. This estimation will make it much easier to determine your battery bank’s size and inverter’s size.

Let’s say you intend to use a rig’s interior lights, water pumps, and your laptop for 2 hours. If it requires a total of 103.5AH and your batteries can’t get lower than 60% without causing damage, you’d need a charging system of at least 258Ah (103.5 divided by 40%). Honestly, it’d be best to get as many amp hours of current as possible with your available space.

For instance, this same person buys a system of four 225Ah 6V batteries and wires them in series with parallel capabilities to create a 450Ah 12V system. They would only draw the batteries down to about 80% based on the scenario laid out above. It would fall right within the safe limit for discharging to ensure damage-free battery usage.

Your solar panels will need to be replaced at some point. In fact, you might be reading this article because your old ones became unusable. But you’ll want to prolong the lifespan of your solar panels as long as possible.

Due to this, buying solar panels with a reputation for being durable would be a smart move. I’d recommend looking for products made from heavy duty materials. These models should have a better shot at making it several years without needing replacement.

You’d be wise to read through numerous customer reviews for each option, as well. These reviews would provide an excellent picture of the panel’s long-lasting capabilities. After all, nothing annoys people more than a product that needs replacing sooner than expected.

RV Solar Panel FAQs

solar panels for travel trailer

Our FAQ section will provide answers to any question or concern still rattling around in your mind. It should act as the ultimate resource to ensure picking the right RV solar panels becomes a smooth, stress-free process.

What is the best solar panel for RV?

Choosing the top-rated solar panels for RV, trailer, or camper usage shouldn’t be complex. But there isn’t a single answer to the question of the top-rated solar panel for RVs. It will end depending on what you deem essential feature-wise and finding a model capable of meeting those demands.

Once you do find this model, the most suitable solar panel for RVs will be in your possession. It ends up being that simple at the end of this process.

Who is this for?

RV solar panels happen to a unique device capable of converting the sun’s energy into usable electricity for a motorhome. But why these devices are worthwhile investments comes down to two primary abilities:

  • Charges Your “House” Batteries: Solar power can offer a slow, reliable charge to your batteries. This method happens to be the way batteries are built to be charged and increases their lifespan. It’s a lot like a car battery; if it sits too long, its longevity will suffer and it might not be able to hold a charge even when charged back up.
  • Provides Electric Power: You could be in the most remote location in the world, and solar panels will still be able to provide power for your onboard devices. It could also be a godsend when you find yourself in an emergency and need a backup power source.

Given these two abilities, I don’t see how solar panels wouldn’t be a good fit for most RVers. It’s a sensible way to ensure there’s always enough power for powering the essential appliances onboard your rig.

What are the different types of solar panels for RV?

RV solar panels are usually separated into three types: polycrystalline RV solar panels, monocrystalline RV solar panels, and amorphous RV solar panels. I’m going to discuss a little about each one to ensure you know what type fits your situation.

Polycrystalline RV Solar Panels

Polycrystalline solar panels are usually constructed from several silicon blocks and contain several small solar crystals. Rig owners have been using them on their recreational vehicles for a long time to utilize solar energy.

These panels are a popular choice because they take up half the space of amorphous types and are only slightly less effective than monocrystalline options. In many cases, buyers end up thinking they’re the best of both worlds.

Monocrystalline RV Solar Panels

These solar panels are built from one large silicon crystal and contain a high charge output. Due to these factors, monocrystalline solar panels are considered more efficient than other types. You can also expect them to supply and produce more elevated amounts of power in low light situations.

Rig owners who intend on camping in foggy areas might consider buying these panels over the more popular polycrystalline options. In these situations, you aren’t going to find a more valuable solar panel type.

Amorphous RV Solar Panels

Amorphous RV solar panels, also known as thin-film panels, are created by spreading silicon on a large bed. This building process guarantees these solar panels don’t have an expensive production cost. As a result, they have the lowest average price tag of any types.

But they also produce the least amount of power among their fellow solar panels. Plus, it requires about three times more space on your roof than polycrystalline or monocrystalline options to provide the same power supply.

How does an RV solar panel work?

Understanding the basics of how an RV solar panel works isn’t a complicated process. These devices capture sunlight and convert it into electricity, which passed through a charge controller. It’s then fed at an optimal current to your RV batteries for storage.

In more scientific terms, the process is called Photovoltaics: converting light/photons into electricity/voltage. It’s also important to note these solar panels are composed of many smaller units called photovoltaic cells.

Solar panels work by allowing light particles (photons) to knock electrons loose from atoms, which produces flows of electricity. This process has become more and more efficient over the years as technology improved.

As I noted earlier, most solar panels will work at 15% efficiency, which conveys that 15% of the sunlight captured is converted into usable power for your RV. But the latest models have increased this percentage to higher levels, topping out at 21% efficiency.

You should also know that your rig’s batteries will store the power generated by these panels. Solar power happens to be somewhat sporadic, which means you can’t use it effectively based on what your panels are getting from the sun at a single moment.

Like I stated before, the stored energy is accessible in two ways. The first method would be direct access for 12V DC appliances. It’s also possible to use an inverter and convert the current into 110V AC power to run AC devices.

Are solar panels worth it on an RV?

RV solar panels aren’t a necessary investment, but they’re a beneficial one. These products provide several advantages and could make your RVing lifestyle much more manageable. Let’s look at a few to see whether buying these panels would be worth it for you:

  • Solar panels are a cost-effective way of obtaining power for your rig.
  • Their power source is inexhaustible, as the sun is not going away anytime soon. Winter months and cloudy days even produce some sunlight from time to time.
  • It’s a clean power resource, which is good for our planet. After all, solar panels don’t burn fuel and don’t produce exhausted fume or waste.
  • RV solar systems don’t require much maintenance. These systems don’t have any moving parts, which means there isn’t anything to break. Once they’re installed, these systems can last several decades when cared for and maintained properly.
  • Solar power systems have little to no recurring costs. Rig owners who decide to expand their systems for more power can easily do so without revamping it entirely. Therefore, the expenses remain way down compared to other means of powering your rig.
  • You can expect these panels to extend your battery’s lifespan. In most cases, RV batteries will last from two to three years and cost a lot of money to replace. A solar power system can increase their lifespan from anywhere between 50% and 75% longer. Therefore, you won’t have to replace your rig’s battery for six or even eight years.
  • RV solar panels provide the freedom to enjoy even the most remote locations. The sun and your stored energy will always be there to provide power when it’s needed.

But RV solar systems aren’t perfect as there are some disadvantages, as well. These disadvantages boil down to an expensive initial investment and complicated installation processes.

In my opinion, these two issues shouldn’t stop a person from seriously considering an RV solar system. Their provided benefits are definitely worth paying extra upfront and dealing with a complex setup.

How do I choose a solar panel for my RV?

I’d suggest following our buying guide above to clarify what RV solar panel fits your needs. You just need to use the information during your search and the right choice should become rather apparent.

What is the price range of solar panels for RVs?

The price of solar panels for campers can vary dramatically. In most cases, the difference comes down to a solar panel’s power output and type. For instance, a 200 watt solar panel for RV like Newpowa’s 200 Watt RV Solar Panel will cost more than a 100-watt option.

But regardless of power output and type, most RV options will cost between $40 and $200. So for buyers who are creating a budget, this range would be an excellent place to start. They can then use factors like power output and type to narrow their parameters significantly.

What other equipment will I need to use solar in my RV?

Complete solar power systems for RVs will need much more than panels. Buyers must obtain solar charge controllers, inverters, batteries, and other necessary hardware. All of these components are crucial pieces to effectively using RV solar systems.

Of course, RVers can always buy a solar power product like ExpertPower’s 5KWH 12V kit, which comes with battery and inverter as well as panels. I often recommend this route, especially to people who aren’t experienced with going green.

What is the best size solar panel for a motorhome?

Most motorhomes with solar panels use 100-watt or 200-watt options. These panels often fit and mount very easily on RV roofs, making the installation process less burdensome.

In my case, I started by purchasing a 1000 watt complete RV solar system with batteries. It came with five 200W panels that meet my needs perfectly. I’ve since upgraded them to better quality options, RICH SOLAR’s 200 Watt RV Solar Panels, but the system was a solid starting point.

What is the highest watt solar panel for an RV?

400-watt panels are the highest output I’ve seen used in RV solar power systems. But this rating is a bit of a rarity for motorhome usage. As mentioned earlier, most experts recommend using 100W or 200W panels to provide RVs with solar power.

Is 200 watt solar enough for RV?

A 200w RV solar kit with inverter is the lowest output anyone will use on an RV (most people will go for 600W). Of course, 200W won’t get them much as it’ll only run a 12V fridge. But some people utilize a panel this size to save electricity as RV refrigerators often use much more power than people realize.

Anyone who wants to use a 200w solar system should consider buying Renogy’s 200 Watt 12 Volt Monocrystalline Solar Panel Starter Kit. It’ll offer an excellent starting point for building an extensive system in the future.

Who makes RV solar panels?

As you might expect, several manufacturers have thrown funds into making RV solar panels. It has become a rather lucrative marketplace over these last few years. However, all these new brands have made separating the top ones from the lousy ones much more difficult.

But if you stick to the brands mentioned in our product review section, I don’t see why you wouldn’t come away with top-tier solar panels. Each of these brands has gained a stellar reputation for providing excellent options within this marketplace.

Monocrystalline vs. polycrystalline solar panels for RV: Which one is better?

Both these types could provide rig owners with usable solar power for many years. But choosing which one’s better comes down to your circumstances. For instance, RVers looking to travel in foggy places regularly should invest in monocrystalline solar panels.

Monocrystalline solar panels tend to work better in low light situations and are more efficient, which could benefit many rig owners. But these models are more expensive than polycrystalline options.

As a result, most rig owners proceed to pick polycrystalline options because of their low cost and only slightly less effective performance. You’ll have to decide whether you value higher efficiency or bargain prices to determine what type best fits your preferences.

How many solar panels do I need on my RV?

The process of determining how many panels are required isn’t a tricky one. You just need to take a closer look at your onboard appliances and their power consumption levels. Use this information to do a few calculations and estimate how much electricity your devices need.

Once this estimation is done, divide it by your chosen solar panel’s energy rating. This calculation would provide an absolute answer to your rig’s required quantity. You’ll also need to make some alterations based on how roof space is left on your RV.

How to install?

Before installing your RV solar panel kit, there are a few safety measures to follow. Each of these actions will ensure nothing dangerous happens during the installations:

  • Review any safety directions within your solar kit’s manual or included materials before starting the installation.
  • Make sure to avoid touching any active electrical parts, such as terminals, when your panel’s exposed to light (even indoors).
  • The installation process should only be done in dry, good weather.
  • Use a cloth or other material to cover panels during the installation. This action will prevent them from becoming charged and causing a potentially dangerous situation.
  • Never step or sit on the panels.

The installation process itself will consist of four straightforward steps. I’ll go over them in detail to ensure you can do this entire process yourself. But remember, there’s no shame in hiring a professional to do the job.

Step 1: Mount The Solar Panels

As you would expect, rigid solar panels will usually need to be installed on your roof using screws. Flexible solar panels are capable of being mounted with either screws or adhesive. Your roof’s membrane will determine what kind of adhesive is usable during the installation. It’s worth noting many solar power kits won’t come with adhesive and only include the mounting hardware.

You should layout your flexible or rigid panels where you want them and ensure everything fits. Proceed to mark their locations after having them where you want them. If you’re bolting the panels on your roof, install the kit’s mounting hardware to the solar panel’s frame. Secure the panel onto the roof.

If you’re using brackets, make sure to apply a sealant under each one to create a water-tight seal. The correct sealant will depend on your roof’s material. Once the panel’s secure, proceed to screw it onto your roof.

Step 2: Run Your Wiring

The next move would be running a power cable from your solar panels down into the rig to the charge controller. You can run the wiring in a couple of methods:

  • Using the Refrigerator vent: The most common method and simplest. After all, it ensures you don’t have to put any more holes in your rig, which is always a plus.
  • Running the Wiring Through/Beside the Plumbing Pipe: Some rigs have their fridge vent located in a slide-out or a significant distance from the battery compartment, which is near where the charge controller’s installed. In this situation, you might want to try running the wire through or beside your plumbing pipe. You should then apply sealant around holes that were made during the process.
  • Drilling: The last resort option is drilling holes where you might need them for the wiring process. I’d suggest drilling near interior walls or cabinets, which allows you to hide the wire inside your rig. Remember, please use a weatherproof entry port or sealant.

Step 3: Connect the Charge Controller

Locate a suitable mounting location for your charge controller, which is extremely close to your batteries to minimize line loss. After mounting your charge controller to the wall, you must make your connections to the power wires dropped through your fridge vent or other location.

You should then use a multimeter to test wire polarity and mark each wire properly using some type indicator, such as tape. Proceed to make your connections to the batteries and solar panels as recommended by your kit’s manufacturer.

Step 4: Install an Inverter

Rig owners looking to use AC appliances like microwaves and laptops will need to install an inverter. These devices will convert your panel’s DC into AC. Your inverter will require an installation location near your batteries and away from several problematic elements: corrosive battery gasses, heat, etc.

Please follow any directions included inside your device’s manual during this installation. But in most cases, you can proceed to connect the negative and positive wires to the inverter. You can then make the connections into your rig’s electrical system. The negative side needs to be connected first when connecting the inverter to the house battery’s posts.

How to use?

Your solar panel’s using process will consist of gathering energy from the sun, which you can then use as a valuable renewable energy source. The device will then charge your rig’s various accessories ranging from laptops to smartphones.

In the end, using an RV solar panel isn’t a complicated process. But I’d suggest reading the manual before using or installing one to ensure maximum efficiency. Otherwise, you might miss a particular direction or tip that could improve your device’s performance.

Any care and maintenance tips?

Most RV solar panels come with included directions about maintaining and cleaning them within their respective manuals. It’s just a simple matter of following these instructions, and keeping them in good shape won’t be difficult.

But in most cases, soft cloths and warm/soapy water should be more than enough to keep them clean. I’d recommend refraining from using cleaning solutions, which could cause damage to the solar panel’s construction.

After reading our article, finding the best RV solar panels shouldn’t be a challenge. I’ve provided you with everything you need to make a smart, responsible decision. You’re now a solar panel expert who’s fully capable of picking the right ones to maximize your rig’s solar system.

In any event, there’s also a comment section below for anyone who does run into any more trouble. I’ll make sure to answer each post and get your search back on track as quickly as possible. Thanks for reading!

RV Solar Components

Solar vs. generator: which is better, installing solar panels on your rv.

  • Frequently Asked Questions

It's increasingly common to see solar panels on the roofs of recreational vehicles (RVs). While solar panels can't replace an internal combustion engine and turn your RV into an all-electric vehicle, they can allow you to run your lights and appliances cleanly rather than relying on a fossil-fueled generator.

Solar panels also give you the freedom to camp off-grid and in places that don't allow generators, rather than having to find a spot in a crowded campground with an available hook-up. And of course, with solar panels, you can reduce your carbon footprint.

Here, we discuss RV solar components and whether they are worth investing in for your next RV trip.

RV solar is not as simple as attaching solar panels to the roof and plugging in appliances. Here are the main components in an RV solar system.

Solar Panels

Panels can be flexible, portable, or rigid. Lightweight flexible panels are better suited when an RV roof is molded rather than flat, while portable panels can be placed anywhere on or off the vehicle, so they can capture sunlight even if the RV is parked in the shade. Rigid panels are much heavier, but they are also more durable and efficient. Panels may generate 150 watts in flexible and portable panels and up to 250 to 300 watts in rigid panels.

Most RVs have two batteries. A 12-volt lead-acid/AGM starting battery is used to start the engine, while a 12-volt RV "house" battery bank is used to run the DC-powered appliances, such as fans, lights, and water systems.

An AC/DC inverter can provide 120-volt power from a "shore power" hookup at an RV campground to power air conditioners, microwaves, and other energy-intensive appliances. In more modern RVs, older lead-acid RV battery banks have been replaced by lithium iron phosphate batteries charged by solar panels and the RV's engine alternator via DC/DC chargers. Together, these provide much more rapid charging and much longer-life battery banks, especially suited for off-grid use.

Some RV owners upgrade to lithium-ion batteries, which are lighter, more efficient, maintenance-free, can hold more energy, and have a longer lifetime. The downside is they cost significantly more.

Solar Charge Controller

A solar charge controller protects your battery by regulating the flow of electricity from solar panels to the battery. The controller matches the voltage output of the solar panels to the voltage capabilities of the battery or batteries.

Many RVs already have inverters that convert DC power from your 12-volt battery into 120-volt AC power used by your lights and other electrical equipment. More expensive inverters can produce more reliable and consistent power needed to run sensitive equipment like electronics or medical equipment.

Transfer Switch

A transfer switch allows you to switch the source of your power from the battery to shore power when parked in a campground, or to turn off a propane source when you are driving.

It's no surprise that solar panels are more environmentally friendly than fossil-fuel generators. Here are some other factors to consider:

  • Energy : Solar panels require adequate sun to charge your batteries, while generators require adequate fossil fuels.
  • Space : A generator and its fuel take up a significant amount of interior storage space. Solar panels are limited by the amount of roof space.
  • Flammability : Fuels for generators (usually diesel, gasoline, or propane) are flammable. Some states prohibit the use of propane generators while driving.
  • Maintenance : Generators need regular maintenance and can leave sulfate residues in batteries. With no moving parts, solar panels need little maintenance other than dust and debris removal.
  • Power Speed : Generators provide instant power. Solar power is slower.
  • Costs : Solar panels usually cost more to install than a generator, but once installed, the sunshine is free and infinitely renewable.
  • Noise : Running a generator at night in a crowded campground will not win you any friends. Absolutely quiet solar panels, however, do not generate anything at night.
  • Emissions : Generators emit greenhouse gases, carbon monoxide, and particulate matter, while solar panels are emissions-free. The manufacture of solar panels is not carbon-free, but neither is the manufacture of generators or the fossil fuels that run them.

Installing solar panels on an RV is no more complicated than installing them on the roof of a home.

Treehugger Tip

If you are uncomfortable or inexperienced in working with electrical systems, hire a professional, such as a professional RV converting company.

When you're ready to purchase and prepare for installation, remember to:

  • Calculate how many panels you will need . Identify the power requirements of your appliances and how many hours per day you use them.
  • Consider what equipment your RV already has . A number of RVs for sale on the market already come solar-equipped or solar-ready. For safety and efficiency, be sure that your RV has heavy-gauge wiring adequate to supply the full amount of power from your panels to your batteries.
  • Buy everything at once . Each component of your RV solar system needs to be compatible with each other. RV solar panel kits are more expensive than buying each component separately, but their components are already compatible.

Installing an RV solar system consists of upfront costs that can be expensive. But these costs may save you money in electricity and fuel costs, as well as camping fees. Solar panels will also reduce your greenhouse gas emissions. If you want to go completely emissions-free, consider a car-camping road-trip in an electric vehicle.

Depending on the amount of sunshine you get and the amount of energy you use, a single 100-watt solar panel is likely to be able to keep a 12-volt DC battery charged. It is likely you'll want multiple higher-wattage panels and perhaps multiple batteries to give you more power for a longer period of time.

Depends on your usage. The larger upfront cost of solar panels, compared to a generator, pays itself off if you frequently rely on solar power off-grid. However, if you only park your RV in campgrounds with shore power, it's probably not worth your money and effort to invest in solar panels.

If your RV is not solar-ready, you may need more than a minimal 100-watt solar panel kit with mounting brackets and a solar charge controller, which can cost as little as $150. With a lithium-ion battery and multiple panels on your roof, the cost can be a few thousand dollars.

Installing Solar Panels on an RV

Man installing flexible solar panel on rv campervan

Before installing solar panels on an RV, you should first know how and where you want to mount your panels. Drilling holes into your RV’s roof is critical, so endeavor to get it right on the first try.

Take note that all RV roofs aren’t the same. Also, the solar panel arrangement that worked for others may not work for you. However, you may not have to worry about hole drilling if you’re using a flexible solar panel .

Still, planning for the best positions to place your panels for durability and efficiency is necessary.

Before purchasing your solar panels, ensure to take detailed measurements of your RV roof. Take note of all AC units, vents, and any other items on your roof that could obstruct your RV solar panel installation. For best results, draw a diagram of your entire roof with the measurements and positioning of the panels.

What You Need for Installing Solar Panels on RV

Once you’ve decided on the perfect positions for your RV solar panel mounting, the next step is to get the right supplies and tools to properly secure the panels to the RV roof.

Here’s a list of some of the tools you need:

  • Cordless Drill
  • Mounting Z Brackets (required: 1 set for each panel)
  • Dicor Self-Leveling Lap Sealant

How to Install Solar Panels on RV in 7 Easy Step -By-Step Guide

Installing solar panels on an RV will be seamless if you follow these seven easy steps.

Step 1: Create a Position for the Solar Panels on your RV Roof

Before proceeding with your RV solar panel installation, create a better position for the solar panels on your roof. Double-check if the panels properly fit in the position before drilling holes into your roof.

Keep in mind that the process will differ based on the type of solar panel you have. For instance, rigid panels must be attached to the RV roof using screws. Flexible panels are mounted with adhesive, although they can also be mounted with screws.

It’s worth noting that the material used in building the upper layer of your roof will determine the type of adhesive needed. As a result, many RV solar panel kits don’t come with adhesive. Rather, they only come with the mounting hardware.

Ensure the panels are mounted in a position where air conditioning and vents won’t shade them.

Step 2: Connect Mounting Brackets to Each Solar Panel and Set them Aside

The next step is to attach mounting brackets to each solar panel. As earlier mentioned, the RV solar panel mounting process may differ depending on the panel type.

However, you must install rigid panels with screws by drilling into your roof. They can be fixed tilt-mounted or affixed flat to your RV roof.

Step 3: Identify the Spots Where you Need to Drill Holes in your RV Roof

Identifying the spots where you need to drill holes on your RV roof applies when installing rigid solar panels with a fixed mount. In such a case, you must bolt the brackets tightly based on your panel’s positioning.

Then, apply sealant underneath the brackets to keep the seal airtight and prevent potential roof leakages. However, you don’t have to drill holes if the panels have flexible designs. Such designs can be mounted with adhesive attached directly to the roof surface.

In addition, removable types, like EcoFlow Portable Solar Panels, have a foldable design and portable carry case. They’re easy to set up and require no installation.

Step 4: Drill a Pilot Hole in Your RV Roof and Screw Your Mounting Brackets

Position your solar panels and mark where you need to drill holes. Then, drill small pilot holes into your RV roof where your brackets will be screwed down. Ensure the holes will hit studs in your RV so your panels are secure.

Then, fill the holes with a small quantity of the Dicor sealant to help ensure that everything remains watertight. Although all RVs are different, the studs are usually visible with a 2-3-inch-wide gray line that goes width-wise off the roof.

Step 5: Using Butyl Tape, Line the Bottom Edges of Each Panel

Line the bottom edges of each solar panel with butyl tape and arrange the panels in place. Covering the panels with butyl tape helps add security to your panels and prevents them from flying off.

Step 6: Use the Screws from the Mounting Kit to Connect the Panels to the Roof

Attach the solar panels to your RV roof using the screws from the mounting kit. Ensure that the panels are properly placed in their mapped-out positions.

Step 7: Apply a Good Amount of Dicor Sealant

Apply a generous amount of Dicor sealant around and on top of the mounting brackets to seal everything off. Make sure to apply the adhesive directly to the butt joint in the roof surface and around the mounting brackets to seal them off from sun rays.

Attaching Solar Panels to RV Roof Without Drilling

An RV with a solar panel Installed on top of the roof

After deciding the type of solar panel you’d love to use, it’s necessary to consider mounting it. Depending on your chosen type, there are different methods of attaching solar panels to an RV roof without drilling.

Portable RV Solar Panels

Portable RV solar panels are great at harnessing the energy of the sun. They’re great alternatives to traditional installations for RVers willing to undertake a DIY project. These panels require a simple setup and are ready to use.

The two most common portable RV solar panels are foldable and suitcase solar panels. Foldable solar panels have more than two panels and fold up in an accordion style. To set up this solar panel, all you need to do is attach the clamps to the battery terminals, and you’re good to go.

On the other hand, the suitcase solar panels come in a folding set of two 50-watt panels. An adjustable kickstand allows it to stand upright or at the desired angle. To set up this panel, attach the alligator clamps to your RV battery’s negative and positive terminals and connect the panels to the attached solar charge controller.

RV Solar Panel Corner Brackets

One of the most effective methods for mounting solar panels to your RV roof without drilling is using corner brackets. These brackets are made of ABS plastic. They’re usually attached to the four corners of the solar panels and adhered to the RV roof using silicone glue.

Corner brackets are only for aluminum-framed, rigid solar panels. They don’t work with flexible panels. To install these brackets, you’ll need to place them on all spots on the panel, mark holes, and drill them through each marked area.

Then, fasten the brackets to the solar panel using the provided bolts and nuts. Apply silicone adhesive, preferably Sikaflex 252 , to the underside of the brackets and place it in the desired roof’s position.

VHB tape is a lightweight, affordable option for mounting solar panels without drilling. It’s an extremely strong double-sided tape that can be applied quickly and easily to solar panels.

Despite its ease of use, VHB isn’t strong enough to adhere rigid solar panels to an RV roof. Hence, it is strictly used on flexible solar panels only. To apply VHB tape, remove the plastic layer from one side of the tape and stick it to the solar panel’s bottom edges.

Then, remove the plastic layer from the other side of the tape and firmly press the solar panel onto the desired roof location. When applying this tape, ensure that the area is dust-free and isn’t too cold outside.

RV Solar Panel Wiring Diagram

After sizing your RV system and the panels, the bulk of work starts! Below are different RV solar panel wiring diagrams. Each diagram illustrates how to connect the solar panels, battery bank, and charge controller.

100W RV Solar wiring diagram

However, the amount of power a 100-watt solar panel can provide depends on factors like the weather, location, type of charge controller you install, and time of year. A 100-watt solar panel provides about 30-32 amp hours per day.

200W RV Solar wiring diagram

2 RV solar panel wiring diagram wired in series

A 200W RV solar panel system is enough to power small 12V appliances, like a sink pump, a cell phone signal booster, and a laptop. It’s less likely to power a portable refrigerator full-time. So, it’s a good setup for supplementary power.

This RV solar panel is relatively small and has an easy setup. Unless you’re considering wild camping in your RV, this panel gives you reliable access to shore power.

Besides, it can run a small, energy-efficient fridge, making it a good option for small campers. However, if your ideal solar system is larger than 2200 watts, build the system with scalability in mind.

300W RV Solar wiring diagram

This panel provides approximately 90 to 96 amp hours daily. Since you may be unable to recharge the batteries daily, consider having an alternative (as a contingency) to avoid cycling the batteries more than necessary.

Overall, 300-watt panel systems reserve a day or two, depending on your usage.

A 400-watt solar panel system gives you a couple of days in reserve, depending on your usage, without other sources of recharging. It’s enough to run your roof vent during the day and night to stop condensation.

In addition, it can recharge small devices on a USB, like tablets, kindles, and phones.

800 watts of solar power is enough for even the largest RVs and campervans. Large RV solar panels provide about 200 to 256 amp hours daily.

They’re enough to run a large fridge, an inverter for a TV, a coffee maker, and charge laptops. If you plan to live in a camper during the winter , the 800W is a full-service luxury.

With large RV solar panel systems, there’s no need for driving or shore power. Although you’ll always need to monitor the battery levels and usage with a solar system this size, you’ll comfortably have enough energy to meet the needs of four people.

Materials Needed for Wiring Your Solar Panel into Your RV

When wiring your solar panel, there are certain materials you must have in place. Some are batteries, mounting brackets, connectors, solar panels, cables, and an inverter.

All the necessary materials must be available, whether you’re wiring your solar panels in parallel or series. While there are numerous inverters, 300W, 600W, 1000W, and 1500W are the most common for solar panels between 100W and over 400W.

The most commonly used alternator chargers are B2B chargers and battery isolators. Wires and fuses are additional parts for all solar systems. In all, before choosing a solar panel system for your RV, make sure to research all its specifications.

How to Wire the Solar Panels into Your RV

After mounting solar panels on your RV roof, the next procedure is to start wiring them. Below are the actual steps for wiring the solar panels into your RV:

  • Mount the RV solar panels to the roof using the parallel or series method.
  • Attach the charge controller to the RV’s interior near the battery bank.
  • Run wires from the solar panels to the charge controller with a circuit breaker or fuse.
  • Connect the charge controller to the battery bank 
  • Then, connect the solar panels.
  • Caulk and seal any holes or exposures created during the installation process. If using an inverter, it should be mounted very close to the battery bank.

Parallel Wiring vs. Series vs. Parallel Series

In series wiring connections, the negative cable of one panel goes to the positive of the second one, the negative of the second goes to the positive of the third, and so on. Then, the two unused cables from the first and last panels go into the charge controller.

Wiring in series means the panel’s amperage remains unchanged, but their voltages are combined. The negative and positive cables often go into a combiner box for parallel wiring connections. One thick positive cable and a negative cable go into the charge controller.

Sometimes, the MC4 branch connectors are used instead of a combiner box. Parallel wiring means the panels’ voltage remains, but their amperages are combined. The series-parallel connection is usually used with numerous panels.

It’s a combination of the two other wiring methods, which allows you to adjust the amps and voltage of your solar array to the properties of your charge controller. For instance, you can create two strings of panels with high voltage but wire them in parallel to combine their amperages.

Wiring your RV Solar Panels in Parallel

12 volt parallel RV wiring connection

Wiring RV solar panels in parallel is when the positive and negative (+ and -) wires are grouped. This type of wiring allows each panel to operate on its own.

Solar panels wired in parallel require higher-gauge wiring because the amperage is the wire gauge’s limit.

Don’t wire your solar panels in parallel for units of over 500 watts because you’ll need to buy expensive, thick wires to make the connection efficient.

Wiring your RV Solar Panels in Series

24 volt RV series wiring connection

The lowest-performing panel in series wiring connections sets a limit on the output. All other panels will be removed if one panel is in the shade.

Connecting your solar panels in series doubles the voltage going through the wires while leaving the amperage unchanged.

Use an efficient charge controller. Voltage is the reason why charge controllers have a limit. Hence, RV solar panels wired in series require a more expensive charge controller.

Wiring your RV Solar Panels in Series-Parallel

RV Solar Panels wired in Series-Parallel

Wiring RV solar panels in series-parallel means that you have multiple series that you’re wiring in parallel. For example, if you have four solar panels, you could have two sets of two panels.

While one series might be wiped out due to a panel in the shade, the other can still perform at maximum capacity.

You double your voltage and amperage rather than quadruple for a four-panel array wired in series parallel. This allows you to limit the gauge of your wires and the size of your charge controller.

Final Words

The biggest determinants of a solar panel RV installation are your budget and power demands. Although you may consider hiring a professional to take care of the installation, it can also be a seamless DIY project. All you need to do is follow the steps in this article and rest assured of a perfect RV solar panel mounting and a better off-road experience.

If you’re using a flexible panel, you can use adhesive to fix the panels. Run the wiring through a conduit to a cable entry plate and connect it to a charge controller. The installation and wiring materials are affordable and easy to access.

Once your solar panel system is installed, maintain and inspect it regularly to ensure optimal performance. Neglecting routine maintenance can lead to reduced efficiency and potential issues.

Although an RV solar installation can cost about $500 to $2,000, the investment is worth it. So, get started with your RV solar panel installation already. Do you have any questions or suggestions on installing solar panels on an RV? Let us know your thoughts in the comment section!

FAQs on How to Install RV Solar Panel

How do rv solar panels work.

RV solar panels convert solar energy into direct current electricity (12V DC), which charges the RV’s batteries and stores the electricity. Passing the 12V DC through an inverter converts it into 120-Volt AC (alternating current), which powers 120-Volt gadgets like a coffee maker. In short, with solar panels, you can power almost anything.

How many solar panels does it take to power an RV?

Five solar panels are enough to power an RV if your total power consumption is 10,000 Wh. However, the number of panels largely depends on your power consumption needs and environmental conditions.

Can I connect the solar panel directly to the RV battery?

Yes, you can, but it’s not advisable. Connecting the solar panel directly to the RV battery can cause explosions and overheating. Instead, connect it to a charge controller. It’ll help guard the battery against overcharging and improve its lifespan.

How many batteries do I need for my RV solar system?

1 to 4 batteries are enough for your RV solar system. Generally, every 100 amp hours of battery storage capacity is enough for a 300-watt solar panel system. So, if you have two 12V or any combination of batteries that sum up to 200 amp hours, your solar panel output shouldn’t be less than 600 watts.

Do you need an inverter for RV solar panels?

Yes, you do. Residential solar panel setups run on DC, so your RV solar system needs an inverter to convert the DC to AC energy. If you’re using solar panels to power your RV, the energy they collect must first go through an inverter before you can use it.

Great question! Lots of Makes and Models of new 5th wheels come standard now-a-days already wired for solar — both roof and ground solar.

One (of many!) ways to find them is to make use of the Search functions on RVT.com to filter down until you find some you like.

First sort your Search by 5th wheels and type “bunk” into the keywords field. You’ll find lots! From there, you can further narrow down your Search by choosing only NEW (under Condition.)

Next, identify a Make and Model you like and run a Search for just that Brand. Then change out the word “bunk” in the keywords field for the word “solar.” Now you can read through those Listings and find out if each unit is solar-ready and / or already solar equipped, depending on your preference.

Hope this helps, Bruce! And, happy RV shopping!

Solar Powered RV: How To Run Your Camper Off Solar

O ne of the greatest things about RV travel is the ability to go off-grid and totally immerse yourself in nature. The thing is, you will eventually run out of battery power doing so. Many people turn to generators to solve this problem, but generators are noisy and are not even allowed in some areas. You certainly don’t want to be running one 24/7, either.

For this reason, we much prefer the idea of creating a solar powered RV for your boondocking adventures.

The only problem? Many people are intimidated by the idea of putting solar power on RV campers. This is understandable; putting solar power in RV trailers and motorhomes can be a huge, expensive, and technical process. Fortunately, there are ways to make solar powered RVs more accessible to the average joe.

In this article, we will teach you how to run your RV off solar, breaking the process down and simplifying things so you can tackle the project with confidence. 

Note: This is a very simplified version of an RV solar power system. There are many things you can do differently to make the system work best for you, but this will get you started. 

THIS ARTICLE MAY CONTAIN COMPENSATED LINKS. PLEASE READ OUR DISCLAIMER FOR MORE INFO. THIS POST WAS WRITTEN BY JILL GREISING-MURSCHEL , A FAMILY TRAVEL AND RV LIVING EXPERT.

Don’t have time to read a bunch of RV travel posts and reviews? Here are some of our top picks for RV living:

How to Run Your RV Off Solar: What You Need

First, let’s talk about the RV solar supplies needed to get your off-grid electrical system up and running. Gather these items and you’ll be ready to jump into your solar project. 

Solar Panels

First, you will want to grab some solar panels. Many people put a lot of thought into figuring out how many panels to buy based on their electricity usage. Our advice? Skip the complicated math for now and simply get 2–4 panels, depending on what your budget can handle. It’s easy to add more panels down the line. 

We recommend this kit from Renogy , as it is incredibly easy to install and get wired into your system. 

Charge Controller

Another must-have piece of RV solar equipment is your solar charge controller. Without a charge controller, you can’t really connect your panels to your battery safely. The panels linked above come with a controller, but these components can be bought separately from one another if you prefer.

We recommend an MPPT charge controller over a PWM option because it will be a bit more efficient. However, either one will be fine as long as you get one that can handle the amperage put out by your solar panels. 

You’ll also need a bank of batteries in order to store the solar power your panels pull in. This may leave you wondering which is the best battery for RV solar.

In our opinion, the best battery for a camper is definitely a LiFePO4 (lithium-ion phosphate) battery. Fortunately, these are becoming more and more affordable as time goes on, and in our experience, even off-brand lithium battery options such as these work just fine. 

We like lithium batteries because they are 100% maintenance-free, relatively lightweight, and can be discharged completely without issues. They are also far safer to store in enclosed spaces where there’s little ventilation.

That said, if you need to cut costs somewhere, traditional flooded batteries should work fine, assuming you have the weight capacity and the ability to stay on top of battery maintenance, as well as a safely ventilated place to store them.

We also recommend investing in an inverter. As long as you connect your battery bank to your RV, you can use your solar power via your RV’s DC electrical system, which includes your fridge, lights, and vent fans. However, without an inverter, you will not be able to use anything on the AC side of things—meaning the air conditioner, microwave, and power outlets.

There are a couple of options here: You can choose to purchase a large inverter charger (see next paragraph) to take the place of your existing RV converter and wire the new inverter into your RV’s breaker box, or you can choose a smaller portable inverter that you will need to plug things into directly. There are also inverters that do not charge the batteries but can be hardwired into the RV’s system. 

We personally chose to install this inverter charger from Sungold , and it is very convenient when it works correctly, as it automatically switches between inverter mode and charger mode when we connect/disconnect shore power. Unfortunately, the inverter broke after only a month of use, meaning we couldn’t use the inverter or charge our batteries for a couple of months while we fought the warranty folks to fix our issue. Because of this, we kind of regretted this choice and don’t necessarily recommend this product.

On top of the troubles we had with our inverter charge, installing such an inverter is a bit more advanced. Therefore, for this article, we will be focusing on using a more basic inverter such as this one .

No matter what inverter you buy, make sure it is a pure sine wave inverter rather than a modified sine wave version. (If you buy a small inverter from, say, AutoZone, chances are it will be modified sine wave and of no use for this application.) You will also need to make sure your batteries can provide enough power to get the inverter running. Three 100 amp hour batteries are just enough to run our 3000-watt inverter.

Breakers and Wires

You will also need some breakers and wires. 

These include:

  • Battery cables — Bigger is better, so we went with 4/0 gauge wiring for our bank of three 100-amp-hour batteries.
  • DC circuit breaker — This goes between the solar panels and the charge controller. Choose the amperage accordingly. If you’re installing the two 100-amp-hour panel kit linked above, this 25-amp breaker will work.
  • Manual reset inline fuse/circuit breaker — This goes between the charge controller and the battery. Choose amperage accordingly. If you’re installing the two 100 amp hour panel kit linked above, this 40 amp breaker will work.
  • Wiring from the solar panel kit — You might need to add additional 10-gauge wire depending on the length of the runs.

Creating Your Solar Powered RV Setup

Now that you have all of the things you need, the next thing to do is actually install your solar power for RV living. We’ve tried to keep everything simple and provided easy-to-follow instructions below. 

Related Post: Pros and Cons of RV Living Full Time

Create Your Battery Bank

The first thing you will need to do is get your battery bank hooked up and ready to go. If possible, choose a place that is near the location of your factory-installed battery in order to make it easy to tie the new bank into the RV’s DC system. Connect the batteries together in parallel using the battery cables mentioned above.

This video will help you do that:

From there, you will just need to connect the battery bank to the RV’s electrical system using the same cables that were used to hook up the old batteries, using the positive post on one end of the bank and the negative post on the opposite end. If this is not possible due to the location of the battery bank, you will need connect the bank to the RV’s fuse panel, which is a bit more complicated. 

How to Mount Solar Panels to RV Roof

The next thing you’ll need to do to install solar power for an RV is learn how to mount solar panels to RV roof. 

Start by figuring out where you will mount the panels. Clean the area well. Attach the brackets included in the panel kit to the panels using the included screws. Place the panels on the roof—ideally with the brackets resting on top of frame studs—and create pilot holes using a drill. Move the one panel out of the way, put RV roof sealant in each pilot hole, replace the panel, screw the panel onto the roof, and cover the screw and the bottom of the bracket in sealant. You can completely coat the top of the bracket with sealant as well if you want more peace of mind.

Repeat this process with all other panels you install, then give the sealant a day or two to fully cure.

Connecting the Panels to the Charge Controller

Using the included cables, plug the panels into one another using the instructions in the video below. We recommend connecting them in parallel rather than series. 

Next, run your solar panel cables into the RV to the place where your charge controller will be mounted (Preferably near the battery bank). Many people will drill a hole in the roof, but we just ran the cable through a gap in our slide seal, using cord covers to keep everything tidy and in place. You could also go through an existing hole in the roof.

Connect wires to the DC breaker, add a wire of the same size to each side of the breaker output, and connect these wires to the charge controller using the instructions included in the kit. Be sure you screw them down tight, but be careful not to overtighten as this can irreparably damage the inserts.

Linking the Charge Controller to the Batteries

Run a 10-gauge wire from the positive output of the charge controller to the inline fuse/breaker and then to the battery bank, connecting the positive to the same positive terminal/post you used to connect to the DC system. Do the same on the negative side but without the breaker in the middle. 

Once this is done, your solar panels should be charging your batteries and you will officially have an RV with solar power. If you wish to be able to monitor your battery charge level, we recommend a battery monitor. We have this one from Renogy and it has served us well.

Adding an Inverter to the Mix

The last step in creating your solar powered camper? Your inverter. As mentioned above, an inverter is not entirely necessary, but it sure does make your solar RV power system more usable, and the GIANDEL product linked above is incredibly easy to hook up and use. 

All you have to do is connect the cables from the positive side of the inverter to the main positive post on your battery bank and do the same with the negative. 

From there, you can choose to plug anything you need to use directly into the inverter, or you can plug the entire RV into the inverter using a 20-amp adapter. Plugging the RV in will allow you to use your outlets and possibly your microwave (depending on the inverter chosen and your microwave’s wattage). If you have a soft starter installed on your RV air conditioner, you may also be able to use that (though it will drain your battery bank very quickly). Keep in mind, you won’t be able to run everything in the RV at once. 

If you prefer an inverter charger, you will need to learn how to hardwire it in. Many RVers seem to like the Victron inverter charger . 

There you have it, everything you need to know to create a very basic solar powered RV setup. If you’ve been dreaming of having RV solar, why not order the supplies you need and get started right away? You won’t regret it!
