Product Description
Front side performance equivalent to conventional low LID mono PERC:
-High module conversion efficiency (up to 20.9%).
-Better energy yield with excellent low irradiance performance and temperature coefficient.
-First year power degradation<2%.
-Bifacial technology enables additional energy harvesting from rear side(up to 25%).
-Glass/glass lamination ensures 30 year product lifetime ,with annual power degradation <0.45%.
-1500v compatible to reduce BOS cost.
-Solid PID resistance ensures by solar cell process optimization and careful module BOM selection .
-Reduced resistive loss with lower operating temperature.
-Higher energy yield with lower operating temperature.
-Reduced hot spot risk with optimized electrical design and lower operating current.
