The backsheet of a solar panel is a crucial component that protects the photovoltaic (PV) cells from environmental factors and provides electrical insulation. The backsheet is typically the outermost layer on the back side of a solar module. Most panels include solar cells, tempered glass, encapsulant, a backsheet, a metal frame, an inverter, and a junction box. .
