Things to Consider

Sustainable energy is the future. Solar energy is sustainable, powerful, and can be available in most parts of the world. To efficiently utilize solar energy in remote areas or transit, you need to invest in the appropriate technology. Flexible solar panels tend to do this job. Here’s a list of guidelines to invest in the best flexible solar panel.

Flexible solar panel: How it works, its benefits and drawbacks

Top 7 Flexible Solar Panels for RVs, Boats, and Bending Surfaces

Flexible solar panels achieve a certain bendable range to custom-fit surfaces that and uneven and curvy. They are extremely thin and lightweight to enable its function.

These panels and amazingly easy to move around with and are easy to install. Therefore they could be used on any movable vehicle, used in camping sites, cabins, for marine vessels, or any other suitable arena.

There is a reason that these panels do not necessarily come in large sizes. The thermal and mechanical pressure on this panel increases as the size is increased. This causes an imbalance in functionality.

Features to consider before you buy a flexible solar panel

Certain determining features would help you choose the flexible solar panel that is best suited for your needs. These features could be largely classified as mentioned below.


The wattage, voltage, conversion rate, transformation rate all together determine the power output of the panels. The technology incorporated in designing the solar panels plays a crucial role. So far, the shingle and honeycomb technologies have provided to increase power output. The installation of more panels also enables to capture more power and increase the rate of conversion and transmission. All these aspects together would help you weigh the power output provided by the product.


The efficiency of the flexible solar panels is measured by its capacity to produce specified output in different weather conditions without compromising its longevity. Most of the time, these panels are used on vehicles to tap energy on the move or when you’re in remote locations. Therefore these need to be built to handle nature’s ruggedness.


Flexibility is the key feature of this product. More flexible the panel, the better are the chances of it fitting in curved and uneven surfaces. The most flexible models on the list are produced by Renogy – they are up to 248 degress flexible.The concept enables these panels to fit flush on the surface and access maximum sunlight. The bendable feature achieves these two aspects without complications.

Size and weight

Top 7 Flexible Solar Panels for RVs, Boats, and Bending Surfaces

Flexible solar panels are way thinner than the rigid panels making them lightweight. The laminate material used to make these panels also contribute to its lightness. Panels of this kind come in manageable sizes suitable for individuals to install and transport them single-handedly and with ease.


The warranty of these products differs from one brand to the other. Many of the products claim to have a warranty period of about 25 years (the RICH SOLAR model, for instance). Most of the times they come with at least 18 months guarantee. But these two features depend on the company policies. Beware of false claims when it comes to the longevity of power output. The warranty and guarantee features should be mentioned in the specifications for the respective product.


Flexible solar panels could be installed by using adhesive tapes, utilizing the given holes to fasten it to the surface, using Velcro, by hanging them or you could make a suitable framework.

First, you need to make sure your surface is clean. Then use a silicone adhesive to stick the panel to the surface.

Some opt for a PVC frame that could be tilted to face the sunlight as it moves.

If the surface is something like a Bimini, you could sow zips on the sides and zip it up.

You have a few options to choose from when it comes to putting the flexible solar panel in your respective facets.

Yes, solar panels need to be waterproof as they are exposed to the exterior of your home or vehicle. Some come with a nonstick coating to ensure that the water cleans the dust and does not infiltrate the panel causing shorting. Down to the junction box of these flexible panels and waterproof.

Without this feature, you cannot have them installed on exterior surfaces or even expect them to function in extreme weather conditions like hurricanes and snowstorms.

Solar panels work their best when they have full exposure to the sun. Their conversion rate and power output it at its best on sunny days.

They do function in low light but the efficiency with which they perform depends on the technology adopted to trap the available sunlight to the maximum capacity and the rate at which this energy is transformed for suitable consumption.

With built-in bypass diodes, you could expect fairly good performance even in cloudy weather. It’s important to have a panel that would provide resistance to loss of battery charge. This could help with better performance. Honeycomb technology and shingle technology also give a lending hand to enhance power output during cloudy weather.

Our Verdict

Considering the product specifications and customer feedback into account these would be our top picks.

Our first choice also is the Renogy solar panel that has the 160 Watt power output. With a wide range of flexibility, permanence, and durability under harsh conditions make it fit to utilize in the testing environment, which essentially is where the best flexible solar panels show their efficiency.

Rich Solar due to its product features, versatility, and outstanding performance is the second-best flexible solar panel. The honeycomb technology increases power output. ETFE feature keeps it running efficiently in ridiculously hot temperatures. The sugar coating to this product is the fact that it is 100% recyclable.

Renogy 100W is quite similar to the 160W version. Due to the lower wattage, the size is quite manageable and it also weighs lighter. You could install two panels to make the wattage output surpass the 160W version. Apart from the decreased power output, this is seemingly a good fit to suit personal needs.
