Electricity production is one of the biggest issues you will face when traveling in a recreational vehicle (RV). You can use liquefied petroleum (LP), such as butane or propane, to generate electricity. But, you’ll find that this costs a lot of money over time and depletes LP reserves that you could have used for cooking. That’s where solar panels can help. There are several options available if you’re looking for the individual best solar panels for RV use, and separate options for the best solar panel kits, so let’s take a look at some of the best.

How much electricity do you need to generate?
This depends on the appliances you use. Each appliance has a power-rating, measured in watts (W). You need to take this wattage and multiply it by the number of hours you use the appliance each day. By doing so, you come up with the watt hours (Wh) required.
Do this for every appliance you use and add up all the Wh totals to create a daily watt consumption figure. You then need to choose a solar panel capable of meeting that Wh figure.
Bear in mind that solar panels aren’t perfect. For example, you can expect a 4W panel to produce between 24 and 28 watts daily. Make sure your panels can produce more watts than you consume each day.
Will you need a regulator?
This depends on the sizes of your battery and solar panels. As a general rule of thumb, you can find out if you need a regulator by checking your battery’s amp hour (AH) rating and divide it by 10. If that number is lower than the solar panel wattage, you won’t need a regulator. If it’s higher, you run the risk of overcharging your battery if you don’t use a regulator.
Why do some solar panels look different to others?
Some manufacturers make crystalline panels, while others make amorphous panels. Amorphous panels have a thin film on top. Most people consider crystalline panels to be the superior choice, as they are more efficient and last longer.
Pros and cons of solar power and the panel kits
Ultimately, you have to factor in all the pros and cons with regards to the use itself, and then the specific products. The pros of solar power are freedom, lack of noise, continuity, increased safety when compared to the alternatives, and low maintenance. The cons include unpredictable outputs, extra space needs of the setup, and of course the high starting costs and the installation. These can be tricky and expensive depending on where do you get it done. Then ideally, you try to choose a panel kit that limits these potentially negative aspects.
The Renogy solar panel offers 100 watts of power and is suitable for use with a 12-volt battery. Better yet, you can link several panels together to up the voltage. This makes it one of the best solar panels if your RV has a powerful battery. It’s one of the sturdiest units around, as it can withstand up to 2,400 Pascals (Pa) of wind pressure and 5,200 Pa of snow loads.
- Generates up to 500 Wh per day
- Features a strong aluminum frame to protect the panel
- Comes with diodes already installed
- 25-year warranty on power output
- 5-year warranty on manufacture and materials
- You may find some manufacturing issues, such as poorly-placed diodes
The Renogy 100 Watts panels are some of the most reliable on the market, as you can tell from the extensive warranties you get when you buy one. Though some people have mentioned product defects, you should be able to clear these up and get new panels thanks to the 5-year manufacturer’s warranty. You’ll also find that combining several Renogy 100 Watts serves your needs if your RV has a large battery.
One of the best solar panels to use if your RV doesn’t have flat surfaces to place panels on, Allpower’s panel offers a maximum of 23.5% efficiency. This compares well against typical monocrystalline panels, which offer between 17% and 19% efficiency. Its low weight also makes it one of the most portable panels on this list.
- Weighs less than 5 pounds
- Can bend up to 30 degrees
- Max efficiency of 23.5%
- Comes with an 18-month guarantee
- Customer service isn’t as responsive as you might like
Allpower’s 100W flexible solar panel is one of the most versatile panels available. While you may want to use it for your RV, it also works well for your home and a range of other vehicles. Its flexibility is a major selling point if you struggle to place traditional panels, plus the low weight means you don’t have to reinforce your RV’s roof. The only worry is the customer service, which is the worst of the three panels listed here.
Much like with the Renogy panels, you can use WindyNation’s 100-watt panels in a series if you need to power larger RV batteries. These panels also come with aluminum frames and the same 25-year power warranty as the Renogy panels, meaning there is little to choose between the two. But, WindyNation’s panel can generate a maximum of 600 Wh per day compared to Renogy’s 500 Wh, though you’ll need ideal conditions for this level of performance.
- Between 300 and 600 Wh produced daily, depending on weather conditions
- Uses Grade-A solar cells
- Comes with a 25-year power warranty
- Additional 5-year warranty for parts and manufacture
- May get damaged during delivery
Some minor delivery issues aside, the WindyNation panels perform well and should be all you need to keep your RV’s battery topped up. The ability to generate 600 Wh in ideal conditions makes this a great option, especially if you spend a lot of time in sunny areas.
