What Are Flexible Solar Panels?

renogy solar panels

Flexible solar panels are photovoltaic (PV) panels made from thin-film technology. 

They are lightweight, bendable, and can be installed on curved surfaces. 

That makes them ideal for use in applications such as boats, RVs, and other vehicles where weight and space are limited.

Solar panels work by converting sunlight into electricity through the use of PV cells. These cells contain materials that generate electrons when exposed to sunlight. 

The electrons flow through the cell to create an electrical current which is then used to power devices or stored in batteries for later use.

Polycrystalline solar panels (the blue ones), while more affordable than monocrystalline panels (the black ones), are known to be slightly less efficient in converting sunlight into electricity. 

The difference in efficiency is due to the structure of the silicon crystals within the cells. 

Monocrystalline panels are made from a single crystal structure, allowing a more direct pathway for electrons to flow. In contrast, polycrystalline panels contain multiple crystal structures, which can create some resistance in the electron flow. 

We recommend avoiding polycrystalline flexible solar panels to maximize the energy you can produce.

Advantages & Disadvantages Of Flexible Solar Panels For RV Campers

We installed a 400-watt flexible solar panel system on our RV a few years ago, but our experience could have been better. 

The primary reason for this was the lower efficiency of flexible solar panels compared to rigid ones.

As full-time RV dwellers who primarily live off-grid, we depend heavily on our solar panels for reliable power. 

Therefore, we must have the most efficient system possible.

That said, flexible solar panels are uniquely positioned in RV solar solutions. 

In certain situations, they can be more advantageous than conventional solar panels. 

The key is to carefully consider your specific needs and circumstances before deciding on the right type of solar panel for your RV.

Here are some of the advantages and disadvantages of flexible solar panels for RV campers:

Benefits & Advantages Of Flexible Solar Panels For RVs


Flexible solar panels hold a distinct advantage over rigid ones due to their ability to conform to curved surfaces. 

This flexibility is particularly beneficial for RVs, which often have uniquely shaped roofs and limited installation space. 

Unlike rigid panels that require a flat surface for proper mounting, flexible solar panels can quickly adapt to the contours of an RV roof, ensuring efficient use of available space and seamless integration with the vehicle’s design. 

For instance, imagine an RV with a rounded roof or multiple curves and angles – Skoolies and Airstreams are great examples.

Installing rigid conventional solar panels is limited to the narrow area in the center of the roof. 

In contrast, a flexible solar panel can easily adapt to these irregular shapes. 

They allow you to make the most of the curved roof space near the edges, providing a reliable source of solar energy without compromising the aesthetics or aerodynamics of the RV.

It’s important to note that flexible solar panels do have limitations in terms of their bendability. The best flexible solar panels for RVs have greater flexibility. Renogy’s panels can flex over 240°.


Best Flexible Solar Panels for RV great for portability

Flexible solar panels offer a significant advantage over rigid ones in terms of their lightweight nature, which helps prevent overloading a vehicle’s load-carrying capacity. 

On average, flexible solar panels are up to 70% lighter than a traditional rigid panel, making them an ideal choice for RVs where managing overall weight is crucial. 

This weight reduction helps your RV stay within its weight limits but also helps maintain fuel efficiency and handling characteristics.

This lightweight feature is particularly beneficial for RV owners as it allows them to install solar power systems without undue stress on the vehicle’s structure or suspension. 

For example, a typical 100w rigid solar panel may weigh around 14 pounds, while a comparable flexible panel weighs just 4 pounds. 

An RV owner can effectively add a solar power system by opting for flexible solar panels while keeping the added weight minimal. 


Flexible solar panels offer a notable advantage over rigid panels due to their low-profile design, which helps maintain the aesthetics of an RV. 

These slim and discreet panels blend seamlessly with the vehicle’s roof, ensuring minimal visual impact while providing efficient solar power.

This low-profile feature can also serve as a security benefit, particularly for stealth campers who prefer to keep their solar setup discreet. 

By not drawing attention to the presence of solar panels, flexible solar panels help maintain a stealthy appearance, reducing the likelihood of theft or unwanted attention from passersby.

Easy Installation

Best Flexible Solar Panels for RV easy to install

Installing flexible solar panels is simpler and more user-friendly than rigid panels. 

Rigid solar panels often require heavy mounting brackets, specialized tools, and considerable time for installation. 

In contrast, flexible solar panels typically come with adhesive backing or Velcro straps, making the installation quick and hassle-free even for those with limited DIY experience. 

By following step-by-step instructions, you can securely mount your flexible solar panels without complex mounting systems, allowing you to quickly start harnessing solar power for your RV.

No Drilling Required

One of the major concerns for RV owners when installing solar panels is the potential damage caused by drilling holes in the roof for mounting purposes. 

With flexible solar panels, this concern is eliminated as they can be attached to the RV roof using adhesive or other non-invasive methods. 

This not only preserves the structural integrity of your RV but also prevents potential water leaks and other issues associated with drilling.

Drawbacks & Limitations Of Flexible Solar Panels For RVs

Lower Efficiency

Flexible solar panels are typically less efficient at converting sunlight into electricity than rigid panels. 

This is primarily due to the thin-film technology used in their construction, which has a lower conversion rate than the crystalline silicon cells in rigid panels. 

As a result, you may need more surface area or additional panels to generate the same amount of power as a traditional rigid panel system.

They Can Get HOT

Due to their design and construction, flexible solar panels get hotter than rigid ones. 

One of the primary reasons flexible solar panels get hotter than rigid panels is the absence of air circulation underneath the panel. 

Rigid panels are typically installed on mounting brackets, which create a gap between the panel and the mounting surface, allowing air to flow and dissipate heat. 

In contrast, flexible solar panels are often adhered directly to the RV roof or other surfaces, restricting airflow and causing heat to build up.

Flexible solar panels are made using thin-film technology, resulting in a thinner, more compact design than rigid panels. 

While this makes them lightweight and flexible, they have less material to absorb and distribute heat effectively. 

This can lead to higher operating temperatures when exposed to direct sunlight.

Higher operating temperatures can negatively impact the efficiency and lifespan of flexible solar panels. 

Since flexible solar panels are already less efficient than rigid ones, this further diminishes their overall performance.

Plus, flexible panels don’t have the advantage of providing a little shade to your RV in summer; instead, they can trap heat and add to the interior temperature. 

To mitigate these issues, you could consider installing them on mounts, but then you’ll lose the advantage of the easy installation.

Durability Concerns

Best Flexible Solar Panels for RV fit where rigid panels can't

While flexible solar panels are designed to withstand harsh weather conditions and impacts, they can be more susceptible to wear and tear over time than rigid panels. 

Prolonged exposure to the elements and potential abrasion from debris can eventually cause damage to the thin-film layers, reducing their efficiency and lifespan.

It’s also worth noting, that flexible panels don’t take kindly to being stepped on. Always avoid walking on them to prevent damaging the solar cells.

Higher Cost per Watt 

Although the overall cost of flexible solar panels has decreased over the years, they still have a higher cost per watt than rigid solar panels. 

This means that while flexible panels may be more convenient to install and handle, they might not always be the most cost effective solution when considering the energy output over time.

Not Totally Flexible

While they can conform to curved surfaces and adapt to various shapes, there is a limit to how much they can bend before being damaged.

When installing flexible solar panels on your RV, be cautious not to bend them beyond their allowable curvature. 

Exceeding this limit may damage the panel’s thin-film layers or internal connections, which could compromise the performance and longevity of the system. 

Always consult the manufacturer’s guidelines regarding the maximum bending radius for your specific flexible solar panel model, and follow recommended installation procedures to ensure optimal functioning and maintain warranty coverage.

Key Factors To Consider When Selecting The Best Panels For Your RV
