Main highlights

The surface of monocrystalline ETFE solar panels is not prone to erosion from ultraviolet rays, wind and rain and will not yellow or age when exposed to outdoor for a long time. At different temperatures, the ETFE material is not destroyed, which significantly increases the life of the solar panel. The time required for maintenance and cleaning is short, which can ensure the efficiency and stability of power generation through solar panels.
The light transmission of ETFE solar panels is relatively high, which makes more sunlight fall on the modules, thereby improving the energy conversion efficiency of the solar panels. The surface uses honeycomb ETFE to collect sunlight from different angles while providing higher light transmission and longer service life, you can get more green electricity and longer time.
Flexible ETFE solar panels have a certain degree of curvature and can be installed in different scenarios on curved surfaces such as ships, caravans, etc. Market leading and easy to move. For quick installation, you can also use glass adhesive. Conventional glass surfaces: solar panels made of glass are relatively fragile and stiff, which limits their scope.
European countries such as Germany and Spain have local warehouses that can be shipped quickly. Thanks to the great guarantee, you can easily return it if quality problems occur during use. Personal 24-hour service is also available.
