What is the structure of the solar panel backplane

  The solar panel is located on the back of the solar panel. It can protect and support the solar panel. It has reliable insulation, water resistance and aging resistance.  

        In general, there are three layers (PVDF/PET/PVDF). The outer protective layer (PVDF) has good environmental erosion resistance, and the middle layer is PET polyester film with good insulation performance. The inner layer of PVDF and EVA have good bonding performance. There are five layers in the section of solar panel: photovoltaic glass EVA, solar cell sheet PVDF and back plate.
