PET film for PV

Film to Maximize Generation Efficiency of Solar Modules

Polyester films for solar cells are used to make backsheets that protect the back side of solar modules. There are two types of film, SG00L and SW30G. The weather-proof PET film, SG00L with triple structure, can be used to substitute fluorine film as the outer material for the backsheet. It acts as both the external and internal material. SW30G protects the backsheet from ultraviolet rays and maximizes the conversion efficiency of modules by raising reflectance.

Product

Product
Product Property
SW00L White film is used in the outermost part of the backsheet as it has good weather resistance
DW00L A film with white appearance and triple structure, capable of playing the role of a core layer and an outermost layer
SG00L Transparent film used for the core layer of the backsheet as it has low heat shrinkage and good weather resistance
SW30G White film that strengthens reflectance of the backsheet with inner ultraviolet film, resulting in high efficiency
