In a hurry? Check out our top pick: Renogy Solar Starter Kit

Solar technology has seen a lot of advancements in the last few years, and it has even extended to the beloved RV. If you enjoy spending lots of time exploring in your RV and you are reading this, you know that the sunlight that shines down on your RV’s roof can be put to good use. Time to collect all that energy and turn it into a cheap way to power your RV!

In the past, solar technology was often inefficient when it came to powering an RV but new technology has developed the RV solar panel. This panel can be used by itself to power up devices or as a part of a group of panels if you need more power.

Here are some tips on what to look for when shopping for the best solar panel for RV use. We have also included some reviews to help you choose which solar panel kit will best suit your needs.

In this article, we’re going to review the following:

Are You a Good Candidate for Solar Power?

  • Do you want a slow and steady way to charge your house battery?
  • Do you camp for more than 2 days in a row without being “hooked-up”?
  • Do you use several electrical appliances during your stays?
  • Do you want to stop solely relying on a generator?
  • Do you enjoy quiet surroundings and do you want to offer the same benefit to your fellow campers?
  • Is your RV often parked / stored in places without electricity?

If you answered yes to any of the above questions, you are a good candidate for solar power!

The following situations, however, are not suitable for solar energy or require an additional source such as a generator:

  • If you must use a large model roof air conditioner (120Vac)
  • If you need to use the furnace or a space heater for long periods (more than 8 hours a day)

Benefits of an RV Solar Panel Kit

Effective way to charge your RV batteries

Your solar panels have the ability to supply a steady and slow charge to your house batteries which maximizes battery life.

Eco-Friendly

Being eco-friendly is one of the most obvious benefits of an RV Solar Kit. You don’t have to depend on any other energy source outside of sunshine. You never have to worry about running out of fuel since solar power is a renewable energy source. It is always available and safe for the environment.

Low maintenance

Solar panels do not have moving components so there is a lower risk for anything to break or needing replacement. All you need to do is occasionally wipe the panel’s surface to keep it clean.

Freedom

My favorite thing about solar panels is that you don’t have to worry about being near an outlet. Sunlight is constant no matter where you are giving you the freedom to hit the road and go wherever your heart desires.

 

How do Solar Panels Work?

Solar panels work by converting the energy they receive from the sun. First, you need to mount the solar panels on the roof of your RV or along the rig when you park it. The number of solar panels you need will be dependent on the amount of power you need.

Once the sun hits the surface of the panels, the energy generated travels through wires to a device called a charge controller. The controller regulates the voltage and current going from the solar panels to your battery and keeps it from overcharging. This device is quite vital as it can preserve the longevity and functionality of your batteries.

The battery or battery bank (two or more batteries joined together) is where the energy is stored. The more batteries you have, the more power you can store.

Most batteries are 12 volt and the power stored in the battery is the DC version. This is the type of power which runs cigarette adapter-style plugs.You can use power directly from the battery using DC plugs.

If you want to use appliances inside your RV like your coffee machine or TV using a standard household plug (AC plug) you will need an inverter to transform the 12 volt to 110 volt. Wires need to run from the inverter to your power box to distribute power to your outlets.

Here’s a good explanation of what Watts, Amps and Volts actually mean.

What Are The Different Types of Solar Panels?

Monocrystalline

monocrystalline solar panel

This is the oldest and most developed of the three technologies. Monocrystalline panels are the most efficient in low light conditions. They are made of a single continuous crystal structure which enables them to give you an equal amount of power output using less space. This makes them a good choice if your space is limited.

 

Polycrystalline

polycrystalline solar panel

Polycrystalline panels were previously thought to be inferior to Monocrystalline because they were slightly less efficient. Even though they have slightly lower efficiencies they are less expensive than Monocrystalline which makes them a popular option for campers.

Amorphous

Amorphous solar panel

Amorphous or thin film panels are a totally different technology to Mono and Polycrystalline panels. A thin film panel can be identified as having a solid black appearance. They may or may not have a frame. Amorphous panels are cheaper and also have a high-efficiency rate. Yet, they are are twice the size of Polycrystalline and Monocrystalline which may not be ideal for an RV roof.

What's the difference between rigid and flexible RV solar panels?

Rigid

Typically, rigid solar panels will have glass panes and an aluminum frame. These types of panels are usually the preferred type of solar panel for Rvs due to their inexpensiveness and durability.

Flexible

If your RV doesn’t have enough flat space, flexible solar panels will work with the curves of your RV. They are extremely lightweight compared to mono and poly panels. You do not need holes drilled to install them, they can be glued directly to the roof. However, since they will be glued to the roof of your RV, you may have a hard time moving them later without damaging the roof.

What to look for in an RV Solar Panel

Power Output

Before you buy an RV Solar panel you need to consider its power output. Typically, the better solar panels are monocrystalline panels since they give you the most power. They also take up the least amount of space which also makes them perfect for the roof of an RV.

You also need to consider how many panels you will need to power your RV. In most cases, a large RV will need at least four if not more while a small one can get away with just one or two panels.

I prefer to look for an RV solar panel that has a higher wattage since it can support several electrical devices. They can also charge batteries to their full capacity quicker and give you a higher efficiency rating every time you connect appliances or devices like your phone or computer.

Expandability

Your power needs can change from when you first start out using an RV solar panel. Being able to add more panels to increase your power output is something to keep in mind. Make sure you are choosing solar panels that are easy to connect with a group of panels.

Size

The roof of your RV can only handle so much. Make sure you have enough room to fit all the solar panels you want to connect. Most RVs can withstand quite a bit of weight but it is always a good idea to check for dimensions and weight.

Durability

When you are using something on the outside of an RV for an extended period, you need it to be durable.

You will find that solar panels tend to wear out and age quickly. Flexible solar panels tend to be stronger since they don’t use glass, however, they have a higher possibility of having their solar cells break.

You should also make sure the solar panels are water-resistant, dust-resistant, and weather resistant. Basically, you want something that can withstand the wear and tear that comes with being outside.

Easy Installation

Easy installation is a must as far as I’m concerned with anything you take along in your RV. You don’t want to lose the plot trying to figure out how to install the panels by yourself, especially when you won’t have technical support around to help you out. Look for lightweight kits with holes that are pre-drilled for mounting.

Items to Consider Adding to Your RV Solar Panel Kit

Charge Controller

Charge controller helps regulate volts and amps in your battery so it won’t overcharge. Most of the solar kits we reviewed come with a charge controller.

There are two types of solar charge controllers:

  • MPPT Controllers, or maximum power point tracking, are efficient and help to increase the performance of your solar panel by letting them operate at the best power output voltage.
  • PWM Controllers, or pulse width modulation, are less efficient as they reduce the efficiency in one part of the solar panel system so that it will cooperate with another part. But, they are cheaper than an MPPT controllers making them a more popular choice.

Batteries

Batteries are an important part of your solar kit installation if you plan on using your stored solar power when the sun goes down. Most solar kits don’t come with batteries, so you will have to purchase them separately. First, you will need to calculate your power needs to determine how many batteries you will require in your battery bank.

Battery monitor

This is great tool to keep track of your battery levels. If you want to monitor the power coming in and out of the batteries and know exactly how many more amp hours you have, this is the monitor you need.

Inverter

This converts the battery power from 12 volt to 110 volt, which is used to power things like your TV’s, coffee machine, and computer.

Wiring harness

Cables which carry the charge from the solar panels to the batteries, and from the batteries to your RV outlets.

 

How Many Solar Panels Do You Need?

Working out your energy requirements is important before you go out and buy your next RV solar panel kit. You need to calculate how many solar panels and batteries you will need based on your appliances and lighting according to the number of hours you use them everyday.
