Best Flexible Solar Panels for RVs

Flexible solar panels are an ideal energy source for an RV. As the name suggests, these solar panels are flexible so they can fit on any curved surface, allowing them to convert sunlight into electricity. These can charge an RV battery, and can also provide energy for technology and light systems within the vehicle.

Solar panels are a popular energy source that benefits the environment, as regular electricity requires the burning of fossil fuels and excessive water use in production. The sun, however, is free. This makes flexible solar panels ideal for an RV, as whilst driving is considered non-environmentally friendly, an RV with solar panels will be more beneficial to the environment than one without solar panels

Best Portable Solar Panels for RV

As with flexible solar panels, portable solar panels are incredibly versatile for an RV due to the semi-permanence. You simply use them whenever you need, and fold them up when they are not needed. This makes them versatile for camping, hiking, and even picnics outside of the RV.

We have found the 5 best flexible and portable solar panels for an RV, along with a handy buyers’ guide and FAQ section to explain the advantages and disadvantages of flexible solar panels.

Best Flexible Solar Panels for RV Buyer’s Guide

Flexible vs traditional solar panels

Flexible solar panels work as the name suggests. These solar panels are bendable and can sit on curved or uneven surfaces without breaking. They are thin, lightweight, and awesome for portability and transportation. They are incredibly versatile and ideal for RVs and cars, but also water-based vehicles such as boats or yachts.

For avid campers or hikers, flexible solar panels are easy to carry. The installation is also incredibly simple as it is semi-permanent, meaning you can take them down in extreme weather conditions or when they aren’t needed. Whilst their paper-thin exterior may seem ineffective, these panels work in the same way as traditional solar panels.

The power outage, measured in Watts, is the same as the power outage on a rigid panel. Where rigid panels are often heavier and less simple to install, flexible panels offer a unique portability with the same benefits as traditional solar panels.

Flexible solar panels are ideal for an RV, because their energy efficiency makes them beneficial both financially and for the environment. They do not require screws for installation, which cancels out the possibility of leakages in the roof, and are incredibly lightweight to prevent damage to the roof also.

This type of energy production does not pollute the earth, does not depend on the burning of fossil fuels, and costs very little in production. For an RV, flexible solar panels are an ideal way of reducing your vehicle’s carbon footprint.

Solar cell types

The most popular solar cell type is monocrystalline. These are incredible efficient solar cells, as they don’t take up much space and can perform well in overcast conditions. They are durable and long lasting, with some cells said to last between 20 and 25 years.

Polycrystalline cells require a cheaper production, which means the quality of the panel is often less durable. They are said to have a lower heat tolerance to monocrystalline cells and are generally less efficient.

Amorphous solar cells are generally the most flexible due to the thin layer of silicon. These cells can work efficiently in overcast or winter weather conditions.

Output and charging compatibility

When looking to buy flexible solar panels for an RV, the output is an incredibly important factor. You will need to know the size of the battery in relation to how much the solar panel can charge. The general rule is to look for panels with 100 or 150 Watts outage, as they can charge 12 Volt batteries as well as supply the rest of the vehicle with a suitable amount of power.

It is, however, recommended to opt for solar panels with a larger maximum output voltage. For example, a 12V battery could benefit more from a solar panel that can produce an output of 18V. This can often be hard to find with flexible solar panels, however.

It is worth noting that the maximum output of flexible and portable solar panels is generally less powerful than traditional rigid solar panels, as flexible solar panels tend to average only between 100-150 Watts.


The key feature to flexible solar panels is the amount of flexibility they can offer. Most flexible solar panels can curve up to 30 degrees, which is ideal for an RV that does not have a flat roof.

Some panels offer more flexibility that can be rolled up, also. Some are less flexible than they are portable, and can be folded instead – these are very versatile for other situations such as camping or outdoors activities.


Whilst flexible solar panels do have their versatile and practical advantages, it is worth looking at the limitations and disadvantages. These forms of solar panels often aren’t as durable as rigid panels, which can last up to 10 or 20 years longer than a flexible panel.

Traditional solar panels also have a larger power output than flexible panels, which is why they are better suited for powering an entire home. For an RV, however, flexible panels are more suitable due to their lighter weight, bendable design, and easy installation.

Frequently Asked Questions

In most cases, the more the merrier, however an excessive amount of solar panels can actually waste energy. We recommend installing around 300 Watts of solar panels on the roof of an RV, which is generally around 3 flexible solar panels. This obviously depends on the battery size, but multiple solar panels can work to charge other aspects of the RV such as an air conditioner.

The main bonus of multiple flexible or portable solar panels is that they don’t all have to be installed and used at the same time, as their lightweight and slim design takes up little to no storage space.

Whilst they have their differences, flexible solar panels are not hugely less efficient than rigid panels. If a rigid panel has a power outage of 100 Watts, then it would have the same outage as an 100 Watts flexible panel. However, they are often not as durable or as long lasting as rigid panels.

Though this means that flexible panels will need to be replaced, RVs are not used as often as the energy in houses (that are better suited for rigid panels). This means that flexible panels are the better choice for an RV due to their semi-permanence. True, they don’t have the same maximum output as conventional solar panels, but multiple flexible panels can be purchased to make up for this.

Monocrystalline solar panels are one of the most long lasting and durable solar panel cells. For rigid panels, this cell type can last up to 20 years. This can double in length with good maintenance. Even in flexible solar panels, these can last up to 15-20 years, but flexible panels in general don’t often last as long as rigid panels.

Most flexible solar panels are waterproof to work efficiently in extreme weather conditions. This is due to secure PET lamination. These solar panels also feature a non-stick coating on the surface, meaning that they are self-cleaning in the rain. This is when solar panels actually benefit from rainwater, as it helps to clean dirt or debris.

Some solar panels, for example foldable ones with fabric outer layers, are not designed for excessive water exposure. Whilst they can withstand light rain in emergencies, the fabric will soak up the water which can damage the quality of the solar panel.

Fortunately, flexible and portable solar panels are easy to uninstall and store, so it is recommended to put them away efficiently when not in use to prevent extreme damage.
