Solar cell: High efficiency(>14.5%) mono-crystalline silicon BSF solar cell.
PV modules frame: Firm aluminum frame with oxidated surface which the thickness 25um.
Iron toughened glass: The surface of PV modules made by high luminousness low iron toughened glass(Fe<0.02%), the thickness is 3.2mm, the most part of wave band is high transmittivity.
Packing material: Ageing resistance EVA. TPT encapsulant material.
Junction-box: Standard output connected-box with by pass diode, and high quality PP material as casing and insulated inside.
Junction-box takes advantage of airproof and waterproot.
