Solar panels that are flexible are very distinct from traditional solar panels that are stiff, rectangular, and enclosed in glass. Conventional solar panels are often seen on rooftops. Instead, flexible solar panels come in all different shapes and sizes, and they are anticipated to be used in a greater number of situations than standard solar panels. Think of just about any location where converting sunlight into electricity is financially worthwhile, and you'll have an idea of where flexible solar panels could be utilized.

Even though most solar panel contractors will only put regular solar panels on a rooftop, flexible solar panels are far simpler to set up, can be purchased online or at some big-box home improvement stores, and are available in a wide range of shapes, sizes, price points, and wattages.

How Flexible Panels Work

Flexible solar panels and regular solar panels both use solar wafers to convert sunlight into energy. Portable solar panels comprise solar cells that are set in a lightweight, sometimes plastic frame. Thin-film solar panels are made of materials such as copper, selenium, and gallium.

Wafers constructed of silicon are used in the majority of flexible display panels; however, these wafers are significantly smaller than the wafers used in normal display panels, measuring only a few micrometers in width on average. Flexible panels, in contrast to normal panels, have layers of protective plastic instead of glass between their layers. Standard panels are sandwiched between two layers of glass. Wafers can be made out of a variety of materials, including graphene, which enables solar cells to be placed on a wider variety of surfaces, such as glass and adhesive tape.

Uses for Flexible Panels

Solar panels that are flexible are able to better fit the curves of their natural surroundings than ordinary solar panels can. Since nature despises straight angles, Awnings, tents, or even the curving roofs of buildings and vehicles are all potential mounting locations for flexible solar panels.


There are many different types of solar-powered boats, ranging from dayboats and recreational craft to barges and houseboats. The undulating curves of many different types of vessels can be accommodated by panels that are flexible, such as the shade canopy that hangs above a deck or the top of a wheelhouse.

Make sure to buy panels that have good seals and are designed to be used in marine environments. Keep an eye out for a minimum rating of 67 for the device's ingress protection. If you install a battery that can store the electricity that is generated by your solar panels, you will be able to sail without the need to make pit stops to refuel.

RVs and campers

The installation of flexible solar panels on the roof of your recreational vehicle (RV) will not transform your RV into a solar-powered electric vehicle (EV), but it will enable you to use solar-generated electricity to power your RV's lights and appliances.

Flexible panels are not only simple to install but also contribute very little to the overall weight of your car. You can avoid the hassle of trying to find a place in a crowded RV park or a campground that has an available hook-up by boondocking on public land. Boondocking refers to the practice of camping off the grid and is free of charge.

There are now recreational vehicles (RVs), motor homes (MHs), and trailers that are either solar-ready or solar-equipped. To get the most out of your setup, make sure that your solar panels produce a sufficient amount of power and that you have a battery that can store that power for later use on cloudy or dark days. Expecting a battery to be able to power an air conditioner through the night is unrealistic, despite the fact that it is much quieter than a generator.

Camping and hiking

If you are going on a trip into the wilderness and are concerned that the battery on your phone will run out of juice, you may attach a flexible solar panel to the side of your rucksack that is exposed and charge your phone while you are on your hike. If you are going automobile camping, you may charge a portable battery by placing the solar panels on the sunroof of your vehicle. This will allow your lanterns to stay lit after dark. When going camping in the winter, a flexible panel is preferable since it can more effectively absorb both direct sunlight and light that has been refracted by snow.

Alternative Rooftop Solar

Due to their low weight, flexible solar panels are an excellent option for rooftops that are unable to sustain the weight of conventional solar panels.

The installation of flexible solar panels is far simpler than that of regular solar panels, which require mounting brackets and sealing materials to prevent roof leakage. Flexible solar panels can be installed without these additional components. Because flexible solar panels do not require mounting brackets or other types of hardware, they may be more readily relocated. This is an advantage if, for instance, you decide to sell your house but keep your solar panels with you after the sale.

Flexible solar panels can also be used to extend a rooftop solar array by filling in spots that are either too tiny or too deformed to fit normal solar panels. These panels can also be added to an existing system in the event that your demand for electricity increases.

Limitations of Flexible Solar

It's possible that one day, solar panels that are flexible will be able to generate more power in smaller locations. In the future, it's possible that we'll be able to generate power by adhering transparent flexible panels to the windows and outside walls of our homes, eliminating the need for anything on our roofs. However, given the current state of the technology, flexible solar panels are not without their drawbacks.

Power Output

Flexible panels typically do not need to have as much power output as conventional ones, typically not exceeding 150 watts in comparison to a normal panel's output of between 250 and 300 watts. This is due to use cases that do not require as much wattage. Although panels with 150 watts cannot take the place of a rooftop solar system that can provide electricity to an entire home, they are more than powerful enough to charge a portable battery in a recreational vehicle (RV) or boat.


When exposed to direct sunlight, flexible solar panels often have a lower efficiency than regular solar panels. In comparison to the efficiency of conventional panels, which ranges from 20% to 23%, they are only able to convert between 7% and 15% of the sun's energy. 12 However, flexible panels are frequently intended for use in low-light environments, in contrast to traditional panels, which are primarily dependent on unimpeded direct sunlight.

However, higher-end flexible panels can be just as efficient as standard solar panels because their solar cells have different layers that absorb a wider array of colors on the light spectrum and perform well in lower light levels. This allows them to work well in environments with lower light levels. They are able to absorb more available light thanks to the monocrystalline cells as well as the curved shape of the panels themselves. Some flexible panels are also bifacial, which indicates that they are semi-transparent and enable light to travel through to the back of the panel, where more solar cells gather more of the sun's energy. This type of panel is known as a "bifacial flexible panel."

When the panels are directly mounted to a metal surface, such as the roof of a vehicle, they will absorb heat from the roof, which will reduce the efficiency of the panels. The interior temperature of the car will additionally rise as a result of the additional covering on the roof. If there is airflow underneath the panels, they will have a greater capacity for energy production.

Longevity and Durability

The longevity of a standard solar panel's construction is one reason why its installation is typically guaranteed for a period of 20 to 25 years. Flexible panels have a warranty that ranges from one to five years but are less durable.

Ethylene tetrafluoroethylene, which is used to make flexible panels, has a longer lifespan than polyethylene terephthalate, which is used to make similar panels. Due to the fact that they are coated with plastic rather than glass, flexible panels are more likely to become brittle and discolored over time, which lowers both their effectiveness and their lifespan.

It is more likely for water to penetrate a panel that has been coated in plastic than one that has been sealed with glass, particularly in items that are lower in cost and of lower quality. The electrical circuits are susceptible to failure if water is present. This is something that needs to be taken into account while dealing with maritime environments.

Weighing the costs and benefits

There are compromises to be made in terms of power, efficiency, and longevity when pursuing flexibility. Before putting money into something you might not end up using, you should evaluate your requirements and do the arithmetic to make sure the investment will be worthwhile.

Are bendable solar panel any good?

In most cases, the answer is affirmative; flexible solar panels typically have an efficiency that is roughly 5-10% lower than that of their rigid counterparts. Do flexible solar panels last? Because flexible solar panels are not as hardy as rigid solar panels and have a greater propensity to be damaged, they do not often have a lifespan that is comparable to that of other types of solar panels.

Why do flexible solar panels fail?

However, if they are bent and flexed an excessive amount, cracks might form in the solar panels. Branches of trees have the potential to scratch flexible solar panels that have been put on automobiles, recreational vehicles, or homes. It is possible that the solar cells will be harmed. Your solar panels' efficiency might suffer a considerable hit from even a minor collision.

How do you go about cleaning solar panels that are flexible?

How to keep flexible panels clean and in good condition. In order to remove sea water, bird droppings, sap, dust, and pollen from the SolarFlex modules, we wash them with fresh water. It is recommended that the surface of the panels be washed with soap and water, wiping carefully, and avoiding the use of any abrasive materials.

What kind of performance can you expect from SunPower's flexible solar panels?

SunPower is widely recognised as the company that produces cells with the highest efficiency. They are utilised extensively in the production of stiff, framed, glass-topped solar panels that are utilised in a variety of commercial and residential situations. SunPower cells have one of the greatest efficiencies of any cell currently available on the market, coming in at approximately 22%.
