What material is the thermal insulation film of photovoltaic panels made of
Polyethylene terephthalate (PET) is the main material of the PV backsheet, providing insulation protection for PV modules. . Most solar panels are still made using a series of silicon crystalline cells sandwiched between a front glass plate and a rear polymer plastic back-sheet supported within an aluminium frame. Once installed, solar panels are subjected to severe conditions over the course of their 25+ year life. Although PET has excellent optical properties, weather resistance, and chemical resistance, its relatively weak insulation properties restrict its application in engineering. . Our front sheet ETFE film provides high levels of resistance to chemicals and weathering as well as low flammability, stress crack resistance, and insulating properties in solar photovoltaic panels. The front sheet also serves as a protective barrier against environmental factors such as moisture. . Solar panels are engineered with a variety of specialized materials designed to withstand extreme temperatures and harsh environmental conditions while maintaining durability and efficiency over decades. . 3M™ Dielectric Tapes perform as reliable insulators when used in conjunction with buses/foils in thin film solar panels.
