The Backsheet range PRESERV from RenewSys offers a wide choice depending on its application. The Backsheet is the outermost layer of a solar module (also known as panels), thus making it a critical component.
All PRESERV Backsheets exhibit high moisture barrier i.e. low moisture premeability and high partial discharge. The Backsheets are avaialable for upto 1500 Vdc module systems, making them the ideal choice for quality-conscious Solar PV Module makers.
The PRESERV Range of solar PV Backsheets are available in White, Black, Transparent and some metallic based options.
KEY FUNCTIONS OF A BACKSHEET
Prevents UV rays, dust, moisture and chemicals from entering the module and damaging the Encapsulant and PV Cells
Maintains module integrity, lending strength, provides electrical Insulation
Supports the Encapsulant and reflects light back to the solar cells to generate more power
Under HAST (Highly Accelerated Stress Test) conditions the PRESERV Backsheet range exhibits an extremely high Peel Bond Strength and hydrolytic properties, to retain the mechanical properties of the Backsheet. The PRESERV range of Backsheets passes upto 3000 Hrs of Damp Heat Testing.
