When it comes to flexible solar panel packaging materials, ETFE film materials appear frequently. Why is ETFE used for packaging solar flexible panels, and what are the advantages of ETFE? ETFE membrane material has four major advantages, which are exactly what flexible solar panels need.

Strong durability

ETFE is stable and durable, able to withstand temperature changes, with a lifespan of 25-35 years. It is not easily affected by environmental factors and can effectively protect solar cells.

Lightweight

Flexible solar panels are commonly used on car roofs, RV roofs, and rooftops, which have certain requirements for the weight of solar panels. ETFE film materials are lightweight and thin, and the use of ETFE film materials for packaging greatly reduces the weight of solar flexible panels. The carrier load is small, and the application range of solar flexible panels is expanded.

Good transparency

ETFE has good light transmission conditions and can easily withstand high temperatures. Ultraviolet rays can be almost completely transmitted, and the light transmittance can reach 95%.

Encapsulating with ETFE not only protects solar cells, but also maximizes the reception of solar light by solar panels, ensuring efficient power generation of solar flexible panels.

High anti pollution self-cleaning

ETFE has a non sticky surface, and the dust and debris in contact with its surface can be easily washed away by rainwater. This means that solar flexible panels using ETFE as the outer material have strong anti fouling ability and require short maintenance and cleaning time, ensuring the high efficiency and stability of solar panel power generation.
