High efficiency Poli-crystalline solar cell
Solar cell: Reduce reflecting by Chemical coating
Every cell adopt twins contact increase the reliablity of the circuit

Tempered glass: Low iron glass increase the mechanial strength and hightransmission rate glass
Using multi-layer backbord, Wear-resistant, anti-tear, anti- perforation
Firmly, light weight, Anti-oxidation AI frame with 4 installation hole, 2 hole for ground bolt hole

One or two junction box, easy to install, safety and environment friendly
Inner side diode, reduce power loss and avoid panel from shade
Long lifetime: ≥ 25 years; Less power decrease.
