Reading Time: 4 minutes

This is a comprehensive list of the best solar panels for RVs in 2021, which allows for easy comparison across panels. Comparable attributes include total watts, total cost, cost per watt, portability, inclusion of battery or inverter, stars out of 5 given by customers, warranty, listed applications, and bonus features. 

Why use solar on my RV?

Being off the grid and on solar allows many benefits to RV owners. 

First and foremost, we can travel for as long and as far as we’d like without having to stop for gas. Nothing is more exciting than being able to drive and camp for a week in Yellowstone without having to leave to find gas. 

Second, using solar energy rather than diesel fuel on an RV decreases costs in the long run. According to the calculations here, solar panels begin to save us money after five 1,000-mile trips. Each additional trip saves $500. 

An RV with installed solar panels

Finally, an RV running on solar emits no fossil fuels into the atmosphere. Climate change is increasing enormously from year to year, so it’s important that we do what we can as individuals to help. 

Finding which solar panels are the best option for your particular needs can be challenging. There are thousands of products out there, and it’s impossible to compare them all. We went through many of the solar panels marketed towards RV, outdoors, and off-the-grid applications. We found the top 20 based on cost and customer reviews, and ranked them by their wattage, cost, cost per watt, portability, stars out of five, warranty, applications, and other features. 

Many of these solar panels are also useful in applications ranging from camping

Hopefully this chart can help you find which solar panel is the best for your RV needs!
