Finding the Best Solar Panels for RV
- Buying Guide

Now that you’ve seen our list of the best RV solar panels out there, it’s time to learn how to decide which one is perfect for you. Just like with any product, you need to keep a few things in mind, and in the next few paragraphs, we will explain what those things are, and give you an excellent starting point for your search.

Things to Consider When Choosing the Best Product

Usage

Before you go out and buy a solar panel for your RV, you should ask yourself what exactly you will be using it for and what your power requirements are.

If all you need is RV battery charging, and you’re looking for a solar panel to provide enough power for that, and only that, you don’t need an industrial-grade huge solar kit. An entry-level, low-price solar package would be more than enough for those purposes. If you want, however, to use the solar panel(s) for powering other electrical equipment like power tools, TV, and other onboard facilities, it’s a good idea to go for a more powerful and robust solar panel system.

If you’re not sure what you’re going to be using the solar panels just yet, and would perhaps like to have a bit of flexibility, our advice is to start small, with a set of two panels. This will allow you to add more panels over time if you should choose to do so.

Versatility

The expandability mentioned in the previous paragraph leads us to our next important factor – versatility. You should know how versatile the solar panel is that you are planning to buy. Expandability is one of the features that make for a versatile board, and it is undoubtedly vital.

Many people start small with just a panel or two, but as they start realizing how great solar power is, they get ‘hooked’ and start expanding their power-generating equipment. It’s good to have that option, and if you think you could be one of these people, look for a solar panel kit that will let you expand to at least 400W in the future.

Another mark of versatility in an RV solar panel is physical flexibility. If your panels are bendable, they can allow you to use them in many situations, and mount them on surfaces that are less reachable and slightly curved. For real adventurers, this will be a huge plus.

Technology

If you’re on the lookout for a solar panel of any kind, it’s a good idea to know a little about the different types that exist and the different technologies they utilize. That way, you can have a clearer idea of what you’re buying and how a specific model can fit your particular needs.

Monocrystalline solar panels are made of one large silicon crystal. This is considered the most efficient solar panel type because it provides high output. Another strength of this type is that it can produce higher amounts of power in low light conditions compared to other panel types.

Made of a few smaller crystals, polycrystalline panels are a popular choice among RV users, because of their flexibility, even though their output is not as high.

Finally, amorphous, or thin-film panels, are created from a thin layer of silicon spread on a large surface. These panels are usually cheaper, as they are not as expensive to make, but they produce the lowest amount of power.

Efficiency

Although you could go out and buy the biggest RV solar panels out there, that’s not always the best idea, because they are going to take a lot of space and might be unnecessarily pricy and difficult to mount. What you need is a mix between affordability, versatility, and efficiency, so take a good look at the output each panel produces compared to its price, size, and weight before making your purchase.

A solar power system is not a cheap investment, so try to pick a kit that will provide you with the amount of power you need for the most reasonable amount of money. In terms of space, you’ll have to decide whether you’d like to sacrifice lots of it for added power output and flexibility of the panel.

Important features to look for

As its name clearly states, this component of a solar panel kit exists to control the charge of the solar panels since the rate at which they produce energy is not the same throughout the day due to the variability of their exposure to the sun. A charge controller prevents panel and battery damage by regulating the flow of electricity to the batteries depending on their state. Most controllers in kits sold nowadays use PWM, which is a type of charging that regulates the width and speed of energy pulses, charging depleted batteries more quickly while slowing down the charge when the cells are at almost full capacity to prevent damage.

To utilize solar power on your RV, you’ll need a deep cycle cell installed in your vehicle. That way, the energy that gets generated for the day through your solar kit can be stored for use later on. Solar panels usually charge 24V or 12V batteries, and some can incorporate 18V batteries, but that is not very common. RVs usually have either two series-wired 6V batteries or a 12V battery. Ampere hours (Ah) are used to measure battery capacity, or how many Amperes a cell can produce for an hour before it gets fully depleted.

This is where we get into the science of AC/DC. No, not the Australian hard-rock band, but their namesake – alternate and direct current. The 12V batteries in your RV only store direct current (DC), or rather, the energy in the cells is only usable as DC. However, most devices run on alternating current (AC). That’s where the power converter comes in. Their power is rated in Watts (W). To operate small appliances and devices such as a TV, lamp, laptop, etc., you’ll need a 1500W inverter. You’ll need an inverter with a bit more power for more demanding devices like specific tools.

Calculating whether you can use the different devices in your RV and therefore the amount of power you’ll need can be a bit confusing and complicated, but if you want to be sure that you’ll have enough electricity to do everything you want to in your RV, you will have to do some math. Remember – your solar panels’ output tells you how fast your batteries can be recharged in full sunlight, while your batterie’s capacity shows you how much power you can store, measured in Ah.

Try to go for a solar panel that is as compact and lightweight as possible for your needs. If you have a large, bulky, and cumbersome solar panel sitting on top of your RV, your experience on the road is going to be less enjoyable. However, if you’re looking for lots of power and efficiency, a lightweight and small solar panel might be hard to find. The larger the panel, the more power it produces, as a general rule. Tracking down a panel that is both compact and highly-efficient might be an issue, so we suggest going for smaller boards, so you can upgrade with extra units when you feel the need to.

How to Install Solar Panels for RV?

Thankfully, the installation of solar panels is not as difficult as it used to be, and it will most likely be a breeze for anyone with a bit of experience with electronics. Most of the models on our list come with pre-drilled holes and hardware for easy installation. However, this doesn’t mean you should take the process lightly, especially if you lack experience with this type of work.

Take great care when installing your panels, because ideally, you don’t want to touch them again once they’ve been set up correctly. Make sure to read the installation manual carefully a few times before starting, even if you’ve done it before since each RV solar panel kit is different. The first and most obvious recommendation is to mount the panels on the roof of your RV, so you can get the most sunlight possible throughout the day.

Another option is to use portable solar panels and place them in a location you think will give them the most exposure to the sun, depending on where you are. This option works best with camping solar panels, but if you plan on purchasing an RV solar kit, the best bet is to mount it on the roof and forget about it. Putting the panels up at a slight angle can help them reach maximum potential, so think about that as you set them up. Try aligning them in such a way as to make them as efficient as possible.

FAQ

Q: What are the different types of RV solar panels?

There are three common types of solar panels. Firstly, we have the mono-crystalline panel, which is made of one large silicone crystal – hence the name. It is the most efficient type, yielding the highest charge output. It can also produce more power in sub-optimal conditions.

The second type is polycrystalline, which contains silicon blocks, each made up of small solar crystals. Producing roughly one percent less power than its mono-crystalline counterpart, this is also an excellent choice.

Finally, we have an amorphous or thin-film solar panel. This type makes use of silicone-coated panels on a large bed. It is the cheapest option, but it also yields the lowest amount of power.

Q: How do RV solar panels work?

No different than any other type of solar panel, RV panels convert the energy of the sun into power or electricity. They create an electric current when they receive sunlight, and the produced electricity then moves into a charge controller. This is what controls the amount of current that eventually enters your battery. From there, the battery will take over, producing DC power. 

To convert that DC power into usable AC that most appliances require, you’ll need an inverter.  Once you have all of these devices set up, you should be able to power your blender, phone charger, or laptop using the power of the sun.

Q: What are the benefits of using an RV solar panel?

One of the most significant benefits of installing solar panels on your recreational vehicle is that you will get clean power quietly and efficiently. Solar panels do not consume any fuel nor create any waste products. There are also no moving parts involved, which means there isn’t going to be any mechanical noise coming from your panel. 

When it comes to practical applications, solar panels do many great things, such as maximizing the battery life in your RV, as well as generating pure power you can use to run your appliances. Another significant benefit is the electrical independence you will have knowing that you don’t need to plug in for your power.

Conclusion

You can get a lot from picking the right RV solar panels and installing them properly. It can charge your battery using the clean and free energy provided by the sun, allowing you to power all kinds of appliances and devices like phones, laptops, and TVs. Just remember to look for the right electrical output, efficiency, and size for you after determining your power requirements as well as the budget you are willing to spend.

Hopefully, this list of best RV solar panels and buying guide will help you make an informed decision and have you on your way to being a more independent adventurer!
