Light from both faces
The rear side adds up to 85% of the front's output wherever the surface below the module is bright.

A dual-glass bifacial panel that harvests light on both faces, so the same stretch of roof or ground returns more energy every year.
A large-format N-type bifacial module sealed between two sheets of glass, built for commercial rooftops, car ports and ground-mounted farms rather than small domestic strings. The rear face converts light bouncing off the surface below at up to 85% of the front's yield, so pale gravel or a white roof pushes real output past the front-side rating. Heat-strengthened glass, an anodised aluminium frame and a 5400 Pa front load rating carry it through wind, salt air and dust for thirty years.




The bifaciality factor is 85% (±5%) of front-side power, but the gain you actually collect depends on what sits under the module. Over a white roof or pale gravel with 135 W/m² reaching the back, a 660 W class module measures about 735 W; dark ground or a flush mount gives far less. Leave clearance behind the panel and the gain rises.
12 years on the product itself and 30 years on performance. Output is guaranteed to fall no more than 0.35% in the first year and to still be at least 88.85% of the rated figure in year 30.
Each module measures 2382 × 1134 × 30 mm and weighs 32.5 kg, so plan two people per panel when lifting. The anodised aluminium frame is certified to 5400 Pa of front load and 2400 Pa from the rear, it runs from -40 to +70 °C, and strings may reach 1500 VDC with a 35 A series fuse.
