dnpSolar Back Sheet materials are designed to provide excellent protection over a long lifetime to photovoltaic modules and ease of handling in production for module manufacturers.
We have divided our back sheets into 3 main families:
The PET type:
The PET type of back sheet comprises a speciality layer of hydrolysis & UV resistant PET, and a normal layer of PET combined with one layer of PolyOlefin. This sandwich results in a good quality product in terms of reliability and UV stability meeting all requirements set forward by IEC standards.
The Fluoric type:
The Fluoric type of back sheet comprises one layer of ETFE and one layer of PET combined with one layer of PolyOlefin. This sandwich results in a high quality product that provides excellent reliability in terms of durability and hydrolysis in combination with high reflectance in order to increase module efficiency and supreme UV stability.
The High Barrier type:
The High Barrier type of back sheet comprises a speciality layer of hydrolysis & UV resistant PET, one layer of aluminium, one layer of normal PET combined with one layer of PolyOlefin. This sandwich enables a first class protection of the module with absolutely no water vaporpermeability, high durability and excellent UV resistance.
Each of these back sheets has been engineered in the DNP laboratories in order to address specific solar module applications.
