Top 10 RV Solar Panels and The Ultimate Buyer’s Guide

RV camping can be an amazing outdoor experience for every kind of traveler. Solar panels are a great addition to any RV experience because of the numerous benefits they offer. Overall, they make your RV experience much quieter because they take away the need for a noisy generator.

They also are better for the environment and keep pollution to a minimum. Most modern RVs have all the amenities that a regular home has which allows you to travel in luxury. With solar panels, you can keep all the electronics and kitchen appliances powered and much more affordable.

Solar panels are also low maintenance. Most of the solar panel parts are built to last, which means you will not spend time constantly repairing or buying new pieces. The battery life of your RV will also be prolonged with the addition of solar panels. Solar panels require less power and energy which means less work for your battery.

Most solar panels are sold in a kit which may include the panels, a controller, mounting brackets, tray cables, an adaptor, and maybe a few other things. Always make sure to read what comes with your kit and what else you may have to buy.

For a solar panel to work though, you will at least need a charge controller, a solar battery, an inverter, and, of course, solar panels. You will also need proper wires and cables to hook them altogether. Make sure the wires are connected to the battery properly or your panel will not work.

The panels you choose will also power your navigation and communication devices and all your appliances inside the kitchen, so picking one that is durable and of good quality is crucial. Since a GPS is often essential to RV campers, you will want to make sure that your RV always has enough power to keep the GPS working. This is crucial for not getting lost and for staying safe on the road.

Solar panels are most beneficial to RV travelers that park their RV off the grid or travel throughout the year. If you only travel a few times a year or always go to a campground, solar panels may not make the most sense.

Hooking up to a local power system at a campground can be cheaper than a solar panel installation. However, if you are on the go often and like to be away from the crowds, solar panels are a fantastic option.

In this article, we will review the best panels for every budget and size. Check out this guide to determine which solar kit is best for you and your RV.

Buyer’s Guide

Check out our buyer’s guide to see exactly how to install panels and how much they may cost you. We will also go over all the questions you may have about power consumption. This is also helpful if you need a professional to get started.

How to Install Solar Panels on an RV

The process to install RV solar panels can be easy with the right kit and the right tools. Each panel is made slightly different and may require a different setup or charging system. Polycrystalline and monocrystalline panels usually charge the fastest.

Use solar wiring to connect your power system. Your kit should come with special instructions to install the solar panels on your RV roof. While there is no special wire for a solar system, most experts recommend an 8 gauge – 10 gauge is even easier to install, but a 6 gauge can be pretty hard.

A solar kit will also need a battery to connect the panels. Some kits come with this as well as the controller for it. A solar power inverter is also needed. This will convert the 12-volt DC power into a 120-volt AC power. This is needed to make sure your appliances do not short and continue to run the same.

Mounting hardware should be used especially when learning how to install flexible solar panels on the RV roof. High-quality mounting hardware will ensure that your panels do not snap or collapse. You may need to purchase different brackets than the ones that come with the solar kit.

Consider buying flat or tilt brackets as well.

Cost of Solar Panels for RV

Solar panels for your RV camper can come at a wide range of costs. It will depend on the size of your RV and what kind of panel you buy. Some buyers decide to buy a cheaper brand or portable kind at the beginning to see how it works and if they will save money. Then, they may upgrade to a better quality. However, some buyers decide to jump all in.

The cost to set up solar panels for an RV is usually somewhere between $3,500 and $4,500. However, the average cost for RV solar panels can vary greatly. The smaller budget will allow you to get solar panels that operate some things in your RV like the TV, the oven, and other small items.

If your RV needs an air conditioner, you are looking at spending more money.

A system around $4,100–5,700 may give you a solar system of around 800 watts. This will allow you to use the microwave and fridge, but it will use up the power quickly.

If you want to run everything but the air conditioner, you are looking to spend around $4,700–5,700 for 1200 watts, so it is only slightly more than the 800-watt option. Some people still get a generator for this level just in case.

For an all-inclusive installation for every device including the air conditioner, you will need a 21500-watt system. This is usually sometimes impossible to get onto the roof, so solar panels may not be ideal for someone that needs to run their air conditioner all the time. It will cost you around $9,500–10,500.

RV Solar Panel Power Consumption

To know for sure which system you need and how much money you will spend, figure out how much power consumption you will use. Most RV campers use about 20 kWh a day. This will be more if you use the AC, cook often, or use several appliances at one time.

RV campers usually only need about two to three solar panels to run their homes, which is very cost-effective. Keep in mind that solar panel installation will save you money in the long run.
