Are Solar Panels Worth It on an RV?

Are Solar Panels Worth It on an RV?If you’re an RV owner, then it’s no secret that electricity is hard to come by when on the road. Sure, you can rely on power at a campsite or park, but what about when you’re not staying there? You’ve heard solar panels could be a viable solution, but you’re not totally sold. Are solar panels worth it on an RV? We did some digging to provide you the answer.

It’s worth considering solar panels on an RV if you boondock often. Even if you don’t, having a reliable source of power is always nice. Of course, there are reasons against RV solar panels, as these can cost anywhere from $500 to $2,000 for a kit.

In this article, we will tell you everything you need to know about RV solar panels. First, we’ll explain how they work. Then, we’ll talk more about the price. By the time you’ve finished reading, you can answer the question of whether you think it’s worth it to have solar panels on your RV.

How Do RV Solar Panels Work?

The goal of this article is to assess whether it’s worth it to consider RV solar panels for your vehicle. As part of that, we should begin with an explanation of how these solar panels work.

An RV solar panel system has several components. It’s not just the panels, even if they play an integral part. There’s also a charge controller, a battery system that generates direct current or DC power, and an inverter that makes alternate current or AC power.

Your solar panels get installed on your RV’s roof, sort of like how if you had solar panels at home, they’d go on the roof of the house. Rays of sunlight stream down to the solar panels. When this happens, it generates an electrical current.

That current travels to the charge controller. As the name tells you, a charge controller dictates the quantity of current the battery receives. As we mentioned, that battery produces DC power. If you need AC power instead, the inverter can transfer it. You can then use such items on your RV as your phone charger, your computer, or even a blender.

Besides acting as a source of electricity, RV solar panels can also charge your vehicle’s battery. Granted, this happens slowly, but it does happen. The natural charging of RV batteries through solar power is better for them than other charging methods. Thus, you get a healthier battery with a good lifespan.

How Much Power Do You Get, Anyway?

Okay, so let’s say you did choose to buy RV solar panels. How much power can they generate? Is it anything worthwhile?

Yes, it is. These solar panel systems come at different wattages. If you had a system with 400 watts and it worked for five daily hours, that would give you 2,000 watts of power to work with. That’s not too shabby.

Of course, we have to be realistic. Your solar panel system won’t run at peak efficiency every day. Getting five consistent hours of sunlight can be difficult depending on where you are, so you don’t quite get those 2,000 watts. You’ll end up with something close, though. The solar panels do still work in cloudy weather, but not as well as they do in direct sunlight.

If you only ride in your RV on short jaunts, you should be able to get by for a few days with about 2,000 watts. Those who travel much more frequently will need a bigger system. Maybe one with 800 watts will work better for you. This has the potential to generate 4,000 watts of power. You could use most RV appliances with that much juice, no problem.

Now, the more wattage you get, the more panels your RV requires, so keep that in mind.
