Finding the best flexible solar panels for your application requires a more careful approach than buying regular panels. To make it easier for buyers to determine the best flexibl solar panel option according to their needs, The choice of a flexible solar panel will depend on many factors,Some of the most relevant ones to the buyer will be power, price, equality, dimensions, warranty.

Power Output

Normally, power outputs for flexible solar panels will be located between 50 and 200Watts, with common values of 50, 100 y 200Watts. The power output gives a reference to the electrical current output that can be obtained from the solar panel. In ideal operating conditions, higher nominal power output will mean that you will be able to supply more energy to the load.

warranty

a good warranty indicates that the manufacturer has confidence in the quality of their product. Possible issues that could be encountered when purchasing cheap flexible solar panels:

Overlapping cells.

Damaged cells.

Inferior cells.

Sharp edges.

Inadequately sealed junction boxes allowing corrosion from water, particularly seawater.

Zinc plated fixings in the junction box which corrode with moisture.

Inferior by-pass diodes fitted or not fitted at all.

Coating Material

Flexible solar panels are constructed by sandwiching the solar cells between layers of a polymer. Cheaper panels will use a polymer called polyethylene terephthalate (PET), while better panels will use ETFE (ethylene tetrafluoroethylene).

ETFE has slightly better light transmittance compared to PET and is also more durable, which is an important consideration when your panel is exposed to the heat and rain in outdoor applications.

Size

That the available space is important to consider when selecting both size and power output

Generally, the width is between 20 and 27 inches while the greatest variations are in the length with typical values between 20 and 60 inches, therefore the panel model must be chosen according to its power taking consider the size factor.

The power output is given by the number of cells and the quality of them (capacity to produce current), therefore low power outputs such as 50W can be obtained with panels of smaller dimensions (length and width, since the thickness is given by cells and coating materials).

Efficiency

The efficiency will be an indicator of how much solar energy can be converted into DC electricity through the solar cells, therefore is one of the top factors that you should consider.

The efficiency values are expressed as a percentage and for flexible solar panels, typically between 20 and 25% and are usually an indicator of the quality of the product, especially of its photovoltaic cells.

The efficiency rating of a panel can make a substantial difference. The higher it is, the higher performance it will have, particularly when sunlight is affected by the weather.

Conclusion

Flexible solar panels have gotten a lot better in terms of performance and durability in the latest years.

Bendable solar panels are made by placing several layers of photovoltaic cells on a plastic backing. Most modern, flexible solar panels consist of monocrystalline layers on top of a durable ETFE (Ethylene tetrafluoroethylene) plastic.

Moreover, we found out that the most powerful flexible solar panels produce around 150-200W. If you want more power, you have to connect several panels but the total power is limited by the manufacturer given the number of panels that can be connected in series/parallel which puts a limit to the total power, if you want more you must use rigid if applicable.
