Introduction of FPV- Floating Photovoltaic Power Station

 

Floating photovoltaic project is to install photovoltaic power generation components on the floating body on the water surface, which has many advantages as follows:

 

It does not occupy land and the water area can be fully utilized.

 

Floating photovoltaic power stations can reduce water evaporation, improve water quality, and inhibit algae growth.

 

Due to the cooling effect of water on photovoltaic modules and cables, compared with ground-mounted systems, floating photovoltaic power stations can effectively improve power generation efficiency.

The Application of EVA, POE Photovoltaic Film Extrusion Line

EVA film is a thin film product which is made of EVA as the main raw material, added with various modifying additives, fully mixed, heated by the production and processing equipment, cast and extruded. The cured EVA can withstand atmospheric changes and has elasticity. After bonding with the glass, it can improve the transmittance of the glass, play a role in enhancing the transmittance and gain the output of the solar cell module. Therefore, it is an ideal packaging material for solar cell modules and glass.
