Product Description

 

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.
