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%,

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.
