Buying Guide

Now that we’re through our product reviews, you might find yourself a little overwhelmed. Solar panel companies have become very advanced, and it may be difficult to pick among all the quality options on the market. In this section, we’ll present you with more info to help make your decision.

We intend on giving you everything you need to pick the best solar panel for your own RV.

How Does a Solar Panel Work?

Let’s start with the basics. Understanding how solar panels actually work will provide you with the base knowledge to compare every product offering on the market.

As you surely know already, solar panels (also called solar photovoltaic devices) convert sunlight into electricity and power. This electricity can be used to power numerous appliances and electronic devices.

In an RV solar setup, the solar panel is typically attached to the roof, where it gets the most direct sunlight. The solar panel collects energy, and transfers it down into the RV through wiring. Needless to say, the more panels you set up, the more power you can create.

But a panel isn’t all you need. There are other important devices which are necessary to actually use the solar panels to power your devices.

The first accessory you need is a charge controller. The controller is attached to the solar panel, and transmits the power from the panels to the battery bank in the RV (which stores the power for use). A charge controller helps to regulate the power being received by the panels, to prevent overcharging the batteries, and other common issues.

You will also require an inverter if you wish to use this power to run your devices in the RV. The solar panels create DC power, and the inverter turns it into AC power, which is what is used to power household devices and appliances.

Benefits of Solar Panels & Kits for RV

The benefits of solar panels for your RV should be pretty clear at this point. They’re a cost-efficient, practical way to generate electricity for your RV. And once you have the components installed, the power generation is free!

Solar panels may not be able to power all of your RV needs, but they’ll still work great as a supplemental source of power to save you money on your power generation over time.

Plus, it’s a decision that you can truly feel good about. “Green” choices are all the rage these days, but solar remains one of the best things you can do for the environment. You’ve got all that roof space on your RV, might as well use it!

Types of Solar Panels & Kits for RV

There are three major types of solar panels – monocrystalline, polycrystalline, and amorphous.

If you read through our buyer’s guide, you’ll have noticed that most of the solar panels we examined were monocrystalline. That’s because this is considered the most efficient material for generating power. Polycrystalline panels are not quite as efficient, but they’re generally quite a bit cheaper.

Amorphous solar panels have been designed to be as thin as possible for maximum portability. That being said, they are noticeably less efficient than the other two panels. Because of this, they aren’t very ideal for RVs, and we didn’t include any on our list.

Key Features to Consider in Choosing a Solar Panel System

How Much Power Do I Need?

Perhaps your most important consideration when buying a solar panel system is how much power you actually need. Unfortunately, there is no simple answer to this question, as it really depends on your usage habits. RVs are notorious for their ability to be decked out with the latest gadgets and appliances, so the answer could be very different among different people.

Either way, you have to not only consider the amount of power generated by your solar panels, but the amount that can be stored by your batteries. After all, there’s no use generating all that power if it can’t be stored.

For this reason, we recommend you start small, and increase the solar panel system as your needs expand. It’s better to under buy than over buy.

Wattage of Panels

In considering how much power can be generated with your solar panels, the best thing to consider is wattage. Wattage refers to the electrical current that can be generated by your panels, and helps you understand how many appliances can be powered at once. More wattage, more appliances and devices can be powered in your RV.

Also, be sure that you have the voltage necessary to support the wattage on the panels.

Ease of Set-Up

Solar panels for RVs need to be assembled so that they’re part of your power generating system. They need to be mounted, and connected to the charge controller, inverter, and battery bank. A quality kit will have everything you need to get this set up. It will come with tools for mounting, organizing cables, running cables through the roof, etc. Many kits on our list include exactly that.

Durability

If you’re putting panels on the roof of your RV, they need to be durable. They need to stand up to wind, rain, snow, sleet, and everything in between. Luckily, pretty much any reputable solar panel built for this purpose will be very durable. Typically, they’ll use some sort of lamination, as well as a frame that is resistant to corrosion. You can rest assured that any panel on our list above can stand up to the elements.

Climate

Of course, solar panels need sun. Therefore, if you live in a climate that gets less sun (looking at you Pacific Northwest) then you might need more panels or more efficient panels to run your RV. It’s an unfortunate reality of this type of power. This is also true of different types of year. For example, the panels charge a lot more efficiently in the summer, when the sun is out for longer.

Conclusion + Top Pick

Thanks so much for reading through our comprehensive guide to RV solar panel technology. We hope this article has given you a comprehensive understanding of the best products on the market, as well as the knowledge to make the best choice for yourself.

That being said, our top pick is the Renogy solar panel. Renogy makes some of the best solar products on the market. No matter which of their kits you purchase, you have everything you need to get set up for a reliable solar system in your RV. The most important part is evaluating your usage requirements, so that you can pick the best Renogy kit for your personal consumption.

FAQ

As a bonus, let’s check out a few of the most frequently asked questions about RV solar panels.

How much power do I need?

The answer, unfortunately, is it depends. RVs are very versatile vehicles, and they can be decked out with a wide range of technology and appliances. Your best bet is to actually use your RV, and build your solar set up as you go. A typical RV user might use roughly 20-30 kWh a day, but it can be vastly different than this.

Is my solar panel waterproof?

Yes! The RV panels on our list are all highly weatherproofed for years of use. Any reputable solar panel designed for an RV will be weatherproofed and durable.
