Description

Bifacial technology enables additional energy harvesting from rear side (up to 25%)

Glass/glass lamination ensures 30 year product life tim e, with annual power degrada ti on < 0 .4 5%, 1500V compatible to reduce BOS cost

Solid PID resistance ensured by solar cell process optimization and caref ul module BOM selection

Reduced resistive loss w ith lower operating current

Higher energy yield with lower operating temperature

Reduced hot spot risk with optimized electrical design and lower operating current
