The SunPower Portable Solar Panel is made with high-efficiency monocrystalline prime solar cells, resulting in the highest (25%) maximum efficiency on our list. It’s lightweight at 4.4 pounds and can bend up to 30 degrees. The built-in MC4 cable connectors make it easy to plug in and out of a solar generator. These panels are backed by a five-year power and two-year product warranty.
- What we like
- SunPower is an industry leader in solar panels, so its products and customer service are reliable and reputable. If you’re anxious about buying from Amazon, this may be a good introductory panel.
- What to consider
- This company usually sells directly from its site, so Amazon doesn’t have a complete list of its panel options. It may be worth reviewing the company’s site or calling a representative directly to learn more.
- What reviewers say
- While there aren’t a ton of reviews on Amazon, most are positive, with reviewers reporting that the panels are easy to install and that they charge well and work well. Some reviewers say customer service is lacking, though this could be because communication is through Amazon rather than SunPower. Reviewers recommend not handling the panels frequently — they’re reportedly not super-durable — but if they’re mounted on a roof, this probably won’t be an issue.

- What we like
- While other designs are mounted flat with glue or require holes drilled for all four corners, the Topsolar Solar Panel Kit has a bracket with an adjustable angle for easy installation and maximum efficiency.
- What to consider
- Topsolar doesn’t sell additional panels you can add to your system to maximize output. If you expect to need more panels for your system, another option may be better.
- What reviewers say
- The most common positive theme in Amazon reviews is ease of installation. A number of customers said they had to change out cords or controllers to get maximum input, and some mentioned that their package arrived damaged, which is always a risk when ordering online.

How much do solar panels for RVs cost?
In general, you should expect to pay anywhere from $100 to $650 for one solar panel, depending on the efficiency of the system and what material it’s made from. And, more than likely, you’ll need at least two panels — if not five or six — to fully go solar.
Keep in mind that the total amount you spend on an RV solar energy system can vary greatly depending on several factors, including the efficiency ratings of your panels, the amount of energy you expect to use, available sunlight and the type of installation you require.
Efficiency
Kami Turky, the founder of Solar Energy Hackers, an online resource for solar information, explained that solar panel efficiency is a measure of how good the solar panel is at converting sunlight into electricity. “A higher efficiency means more power from less sun and space, which is ideal for RVs because they don't have a lot of space, and you want your solar panels to charge your batteries faster, so you can hit the road,” Turky said.
Each solar panel has its own efficiency rating, which expresses how much of the sun’s rays it can convert into electricity. The higher the rating, the more it can convert in a smaller amount of square footage, and the fewer panels you’ll need for your system.
Energy requirements
You’ll also need to know how much energy you expect to use. Most RV solar panels are between 100 and 400 watts each.
Installation type
You can either install the solar panels yourself or pay a company to do it as part of their package. If you go the do-it-yourself route, you’ll need to purchase a mounting kit, cables, alligator clips and other equipment.
What to consider when buying solar panels for your RV
While efficiency and energy capabilities are important factors, there are other considerations when you’re purchasing solar panels for your RV.
- Weight: Regular solar panels weigh approximately 40 pounds, while portable ones usually weigh less than 10 pounds. If your RV has weight restrictions, this is a big factor to consider. The added weight will also mean lower gas mileage.
- System voltage: Most RV owners can get by with a traditional 12-volt system that meets their AC/DC needs. For those with greater energy demands, a 24-volt system may be better (but will come at a higher price).
- Building quality: The three main types of solar panels available are monocrystalline, polycrystalline and thin-film solar panels. Monocrystalline is the most efficient and is made from one silicon source. Polycrystalline panels are made of different types of silicon and are still efficient, but they are a little cheaper than monocrystalline. Thin-film panels are thin pieces of conductive material on a plate of plastic or glass. They’re the most affordable but least efficient option.
FAQ
What other equipment will I need to use solar in my RV?
In addition to the solar panels, you’ll need a charge controller to help prevent overcharging your system, solar batteries for energy storage and an inverter. You may consider getting a battery monitor as well to alert you to the status of your battery.
How many solar panels do I need to run an RV?
How many solar panels you need depends on many factors, including the wattage of the panels, how much sun you get and how much energy you use. It might be anywhere from one to seven panels.
What are the most efficient RV solar panels?
Most RV solar panels on this list hover around 22% efficiency. Some of SunPower’s solar panels have a maximum efficiency rating of 25%, making them the most efficient we found.
