How do RV Solar Panels Work?

RV Solar Power System

It all starts as the sun rises.

As the rays of the sun hit the solar panels of your RV, the solar cells in the panels convert this light energy to electrical current. 

Note: The current produced by the solar panel is DC or Direct Current.

The DC power from each cell is then transferred to a circuit housed in the junction box on the solar panel. The circuit has a positive and a negative terminal that feeds the current with the help of wires to a solar charge controller.

The primary function of the charge controller is to charge your RV batteries. It controls the amount of current flowing into the house batteries and prevents them from overcharging.

At this point, you can use your RV battery to power all your 12-volt DC appliances like charging cell phones, laptops, lights, etc.

However, like your home, your RV has a wide variety of appliances that need 120-volt Alternating Current (AC). This is the same electricity that comes out of the wall outlets in your home.

To transform the 12-volt DC produced by your solar panels to 120-volt AC, you need a power inverter. Now you can run all your RV appliances that use 120V AC, such as TV, refrigerator, coffee maker, etc.

You should be able to run your RV air conditioner or any other appliances if you have enough solar panels, a large battery bank, and a right-size inverter.

What are the Pros & Cons of Using Solar Power for Your RV?

Before moving on to making purchase decisions, we need to understand one more thing.

Is solar power worth it for your RV?

To answer this question accurately, let’s weigh the pros and cons of using solar for your RV.

Advantages of Using Solar for RV

The first and most important benefit for me is, solar makes ZERO noise

Unlike a generator which can bug you and your neighbors, a solar power system does just the opposite. It enables you to enjoy the sound of nature while silently charging your house batteries in the background.

Solar has NO running cost after the system is installed.

Unlike generators, solar doesn’t need any sort of fuel or oil to produce power. All it needs is sunlight to produce electricity. Technically, after the initial cost, solar panels will produce electricity free of charge for the lifetime of the setup.

No harmful gasses are produced while using solar power.

Because solar panels don’t need any combustible fuel to function, they don’t produce any emissions. This makes them an excellent option if you’re boondocking in states with strict emission laws. Plus, you don’t have to worry about Carbon Monoxide poisoning with solar power.

With solar panels, you’ll have little to no maintenance.

Because solar panels don’t have any moving parts, nothing breaks, resulting in less maintenance. Once installed, modern solar panels can serve you for upwards of a few decades or more without any major issues. Just clean the panels from time to time as dust, debris and snow can affect the efficiency of the panels.

Disadvantages of Using Solar for RV

Your RV solar setup is a costly investment.

One of the biggest downsides to installing solar in your RV comes from its initial investment. The solar panel price will vary depending on the type, efficiency, and rated output of the panel you choose.

Apart from the panels, an RV solar setup consists of a charge controller, battery, and an inverter. Of them, your battery will use a substantial part of your budget, especially if you go with lithium.

Solar power is not an on-demand source of power.

Unlike generators, your solar panels can’t produce electricity on demand. Meaning, there is no button that you can press like on a generator to start producing power whenever you want.

You need the right conditions like a clear sky with lots of sunlight for it to work. Moreover, they are useless at night and very inefficient on rainy and cloudy days.

What to Consider when Buying RV Solar Panels?

Before buying solar panels for your RV, you need to know a few essential things. These factors will help you make an educated decision when choosing the right RV solar panels.

Total Power Requirement

The first question to ask yourself before putting a finger on a solar panel is “how much power do you use daily”. Without knowing your power requirements, you won’t be able to determine how many solar panels your RV needs.

To find out how much power you use daily, simply make a list of the appliances you plan to use. The more appliances you plan to use, the larger your solar array and battery bank will be.

I would suggest keeping the number of appliances to the bare minimum. As both solar panels and batteries are expensive. Moreover, the batteries are heavy, which may hinder the balance of your RV.

Before mounting solar panels on the roof of your RV, you need to find out the total usable space available for the panels.

Rigid vs. Flexible Solar Panels

Flexible vs Rigid Solar Panels

Rigid panels are hard solar panels that use tempered glass to protect the solar cells. The glass is strong enough to withstand damages from hailstorms, heavy snow and is scratch resistant.

They are enclosed in an aluminum frame which adds to the strength. They also come in a wide range of sizes to power large and small RVs.

Generally, rigid panels are mounted on the roof, but you’ll find rigid panels available in the portable, foldable, and suitcase form factor.

Flexible panels are soft solar panels that use a layer of plastic to protect the solar cells. These panels can bend to a narrow curve to fit on top of most small teardrop types of campers.

They are very lightweight, which makes them ideal for pop-up campers and use on the awnings of your RV. The soft plastic layer is less resistant to scratches but is less likely to crack in the event of a hailstorm.

Types of Solar Panel Cells

RV Solar Panel Cell Types

There are three main types of solar panels available in the market today:

  1. Monocrystalline
  2. Polycrystalline
  3. Amorphous

Monocrystalline panels are the most efficient and come with a higher price tag. Polycrystalline panels are less efficient compared to mono and thus are a bit cheaper.

Amorphous panels use the latest technology that gives them the ability to flex. But, they are the least efficient and are the most affordable amongst the three.

I would suggest you go with the monocrystalline panels if you have the budget or polycrystalline if you’re short on budget. Amorphous panels are ideal for pop-up campers or campers with curved roofs like Airstreams and teardrop trailers.

Solar Panel Mounting System

There are two different ways to use RV solar panels to charge your house batteries when boondocking:

  1. Permanently mount them on your RV roof
  2. Use portable solar panels 

Roof-mounted panels, as the name suggests, are installed on the roof of your RV. You can hire a professional to install it or do it yourself (more on this later). 

With roof-mounted panels, you don’t have to worry about moving the panels at sunrise and set. On the other hand, roof-mounted panels steal the freedom to park your RV in the shade on a hot day.

Portable solar panels, on the other hand, are not fixed to any one spot. This hands you the freedom to move it and change its angle depending on the time of the day.

However, with portable panels, you have the extra work of loading and unloading every day. Plus, they may grow legs as they are not secured to one place.

Panel Efficiency

The efficiency of a solar panel is determined by the amount of electricity it produces with the sunlight it receives.

The efficiency of your solar panels may vary depending on a wide range of factors. Usually, the solar panels that are available in the market today range between 15-25% efficiency.

The higher the efficiency, the higher the price.

Get the most efficient panels you can afford, as you’ll need to install fewer panels.

Temperature Coefficient

Like any other household electronic device, your solar panels need a certain temperature to perform optimally. 

This is referred to as the temperature coefficient.

Generally, solar panels perform at their best at a temperature below and up to 25° C or 77° F. As the panel temperature goes above this number, your panel’s efficiency comes down by the temperature coefficient of the panel.

For example, the temperature coefficient of the Renogy 100W Solar Panel is -0.37%/°C. This means, for every degree rise in temperature from 25° C or 77° F, this panel will lose 0.37% efficiency.

This may not look much if the increase in temperature is by a few degrees. However, it soon adds up until you find your panels are working like a tortoise.

When buying solar panels for your RV, look for panels with the smallest temperature coefficient number.


The warranty of a product is the direct indicator of its quality.

Getting your RV solar panels from brands that offer longer warranty periods will give a peace of mind.

There are two types of warranty solar panels come with, material and performance warranty.

A material warranty ensures your panel from equipment failure due to environmental hazards or manufacturing defects. Most well-known brands on the market offering up to 5 years of material warranty.

Performance warranty ensures that your panels will perform at about 80-90% efficiency at the end of their warranty period. Most brands offer 25 years and more of a performance warranty.


Like a warranty, the price of a product is also a direct indicator of its quality.

When buying solar panels for your RV, get the most expensive you can afford. With a premium-priced solar panel comes higher efficiency, better performance, and a longer warranty.

Plus, you don’t want to replace your panels every year, so avoid cheaper panels.

How to Install Solar Panels on An RV Roof?

How to Install RV Solar Panels

If you have purchased portable RV solar panels, then you don’t have to worry about installing them on your RV roof.

However, if you don’t like the idea of moving the panels and want to permanently mount them on your roof, then read on.

In short, there are two ways to install solar panels on your RV roof. 

One, you pay a professional to do it for you, which will cost you additional installation fees. Two, you can install the panels yourself.

I like the second way because this will help me learn more about the whole solar system, help troubleshoot and make it easy to maintain.

Installing solar panels on your RV roof isn’t rocket science.

It is pretty straightforward, and the most non-technical RV owner can do it yourself. 

Here is a step-by-step guide to install the solar panels yourself.

Installation Process for Rigid Panels

Step 1: Inspect your roof of any visible damage, as it is easy to fix damages before installing the panels.

Step 2: Map out the floor space available to lay down the panels. Make sure nothing is obstructing the panel.

Step 3: Mark and drill holes for the panel mounts. You can either lay them flat on the roof or use adjustable mounts. Using the caulking gun, seal the holes.

Step 4: Screw in the panels and connect the cables to the charge controller.

Note: You don’t have to drill holes if you have flexible panels. You can fix them on your roof using special adhesives.

RV Solar Panel Maintenance

Investing in solar for boondocking is one of the best investments, as high-quality panels can produce power for over 25 years and more.

Unlike RV generators, solar panels require very little maintenance to retain their peak working condition.

During the dry season, the maintenance will be a bare minimum. All you have to do is keep the panels clean of dust and other debris so that maximum sun reaches the cells.

The rainy season makes the maintenance process much easier as the rainwater washes all the dirt off the panels. Just keep the panels titled and let the rain wash away all the dirt.

Maintenance frequency increases during winter as overnight snowfalls can completely obstruct sunlight from reaching the cells.

Frequently Asked Questions
