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
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 Bypass diodes ------to avoid hot-spot effect.
ØSolar panels 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 4.52W, and 320W Mono Solar Panel has 72 pieces Mono solar cell, so the power of our 320W Mono Solar Panel actually is 325.44W.
Our company has automated production line for solar panel. Good technology, good quality assurance. Strong production ability: 300 pieces 300w solar panels can be manufactured per day. Most of company weld solar cell with artificial manual work. Bad manufacturing technique is difficult to keep consistency of products.
