2.State
PET complex film(PE structure PV back sheet) have several advantages, it has a light texture, easy cutting, anti-aging, corrosion resistance, high barrier, environmental protection and low cost. It has been used by solar module manufacturers popularly. It is an excellent substitute for epoxy, glass, TPT film. In which the white PET complex film thickness of 0.30mm, breakdown voltage up to 25KV, the quality can be comparable with TPT film, but the price is only 30% of TPT film, it is the ideal choice for small solar module.
*We are able to provide all above product in according with customer demand.
