Two working faces, one panel
The clear rear glass turns light reflected off the roof or ground into extra output, worth about a tenth again on bright surfaces.

A dual-glass bifacial panel that gathers light on both of its faces, so the same patch of roof or ground quietly returns more energy every year.
A bifacial dual-glass module built on N-type TOPCon cells, compact and light enough for two installers to handle on a pitched roof, a carport canopy or a ground-mounted row. Its clear rear face collects the light bouncing off the surface below, adding roughly a tenth again to the day's harvest over bright ground. Glass on both sides, an anodized aluminium frame and certified snow and uplift loading keep it producing through decades of weather.




It depends on what sits beneath the panel. The rear face converts light at about 80% of the front's efficiency, and under the published bifacial test conditions the module measures roughly 10-11% above its front-only rating. Light gravel, a white membrane roof or a raised ground mount give the most; a dark roof sitting flush to the tiles gives the least.
15 years on the product itself against manufacturing and material defects, and 30 years on performance: no more than 0.40% loss in the first year, with 87.4% of the rated output still guaranteed in year thirty.
Each module measures 1762 x 1134 x 30 mm and weighs 24 kg - a comfortable two-person lift, and short enough to sit portrait on most domestic roofs. The 30 mm anodized frame takes standard clamps and is certified for 6000 Pa of front load and 4000 Pa of rear uplift, so it suits snowy and windy sites alike.
