Materials of solar panel:


Ø Solar cell------conversion efficency of solar cells: 24%-17%, and ensures high performance and more power under same condition  
Ø Front glass------3.2mm, high transmission, low iron, tempered glass,to enhanced stiffness and impact resistance
Ø EVA------excellent anti-aging EVA, to enhance the rigidity and stability of solar cells
Ø TPT-------TPT hot seal made of flame resistance.
Ø Flame------is equipped with drainage holes in order to eliminate the risk that rain or snow water may accumulate in the frame
Ø  Junction box------Ip65 rated, high quality, with diode protection
Ø Bypassdiodes ------to avoid hot-spot effect.
Ø Solarpanels make from A grade solar cells with high efficiency. We implement strictly A grade solar cells test standard that meet the worldwide standard when we choose solar cells.

Ø Our A grade solar cell comes from powerful  suppliers which is famous on global market, such as LDK Solar Hi-Tech (Xin Yu) Co.,Ltd, CSG PV Tech Co.,Ltd.

Ø one piece of our Mono solar cell is 4.23W, and 320W Mono Solar Panel has  60pieces poly solar cell, so the power of our 250W  Solar Panel actuallyis 253.8W.
