How to Choose Flexible Solar Panels for RVs

Solar power has become increasingly popular among RV owners due to its eco-friendly and cost-effective nature. Flexible solar panels offer a versatile and convenient solution for harnessing solar energy on your RV. In this blog, we will explore the flexible solar panels and provide essential factors to consider when choosing the right panels for your RV.

What Are Flexible Solar Panels?

Flexible solar panels are a lightweight and bendable alternative to traditional rigid solar panels. They are made using thin layers of photovoltaic materials, such as amorphous silicon or cadmium telluride, which are embedded in flexible substrates. This construction allows the panels to be curved or flexed to fit different surfaces, making them ideal for curved or irregular RV roofs.

Benefits of Flexible Solar Panels for RVs:

Maximizes Available Surface Area:

Unlike rigid panels, which require a flat, unobstructed area for installation, flexible panels can be mounted on curved roofs or other unconventional areas on an RV. This maximizes the available surface area for solar power generation.

Lightweight and Durable:

Flexible solar panels are significantly lighter than their rigid counterparts. This weight reduction is beneficial for RV owners, as it minimizes the impact on the overall weight and balance of the vehicle. Additionally, these panels’ flexibility helps absorb vibrations and impacts during travel, making them more durable and resistant to damage.

Easy to Install:

They can be adhered directly to the roof using adhesive backing or secured using fasteners. The installation process is typically simpler than that of rigid panels, which often require drilling and mounting brackets. The ease of installation makes flexible panels an attractive option for RV enthusiasts.

Disadvantages of Flexible Solar Panels for RVs:

Less Efficient:

Compared to traditional crystalline silicon solar panels, flexible panels have a lower energy conversion efficiency. This means that they generate less electricity per unit area. If you have limited space available on your RV, rigid panels might be a better option as they offer higher efficiency and power output.

More Expensive:

Flexible solar panels are generally more expensive than rigid panels, primarily due to their advanced technology and manufacturing processes. If cost is a significant factor for you, it’s worth considering whether the flexibility and convenience outweigh the higher price tag.

Lower Lifespan:

Flexible solar panels typically have a shorter lifespan compared to rigid panels. The constant bending and flexing can cause wear and tear over time, reducing overall lifespan. However, with proper care and maintenance, flexible panels can still provide reliable performance for many years.

Factors to Consider When Choosing Flexible Solar Panels for Your RV:

Panel Type:

There are three primary types of flexible solar panels: monocrystalline, polycrystalline, and thin-film panels. 

Monocrystalline solar panels are widely regarded as the most established and efficient type of solar panel available. They are known for their exceptional performance in various weather conditions and long lifespan. These panels are made from a single piece of pure silicon, allowing for the efficient conversion of sunlight into electricity. Monocrystalline panels can last up to 50 years, making them highly durable. However, their manufacturing process generates some waste, resulting in higher costs than other panel types.


  • High efficiency
  • Requires less space to generate more electricity
  • More tolerant to higher temperatures


  • Most expensive option
  • Less sustainable manufacturing process

Polycrystalline solar panels are also made from high-purity silicon crystals. However, the manufacturing process involves cooling and breaking the silicon into smaller fragments, then melting and forming into cubes. This method is less time-consuming and cheaper, enabling the production of a higher quantity of cells in a shorter period. Polycrystalline panels, though less efficient than monocrystalline ones, offer comparable lifespan at a lower price. They do require more space to generate a similar wattage as monocrystalline panels.


  • Less expensive and cheaper to produce
  • Comparable lifespan to monocrystalline panels at a lower cost


  • Less efficient
  • Less tolerant to heat
  • Requires more space/panels to generate comparable wattage to monocrystalline panels

Thin-film solar panels consist of one or more layers of thin photovoltaic film, such as amorphous silicon, cadmium telluride, gallium arsenide, or copper indium gallium selenide. These panels are lightweight, easy to install, and have a smaller carbon footprint due to their reduced semiconductor material requirements. However, thin-film panels are less efficient than monocrystalline and polycrystalline panels, requiring more space for the same energy output. Additionally, they may not be as readily available as other panel types and have a lower life expectancy.


  • Lightweight and easy to install
  • Lower carbon footprint
  • Quicker return on investment (ROI) compared to other panels


  • Lower efficiency
  • More space required
  • Not as readily available
  • Lower life expectancy


Consider your budget and your value on flexibility when choosing flexible solar panels. While they may be more expensive upfront, the long-term benefits of harnessing solar power on your RV can outweigh the initial investment.


Since weight is a crucial consideration for RV owners, ensure that the flexible panels you choose are lightweight. Opting for lighter panels can help maintain the vehicle’s balance and reduce fuel consumption during travel.


Check the warranty offered by the manufacturer. A longer warranty period indicates the company’s confidence in the product’s quality. Choosing panels with a warranty covering both performance and manufacturing defects is advisable.

Final Thoughts:

Flexible solar panels offer a range of benefits for RV owners. By considering factors such as panel type, cost, weight, and warranty, you can decide when selecting flexible solar panels for rv. Embracing solar power on your RV reduces your carbon footprint and provides energy independence while exploring the great outdoors.
