The clear rear glass collects light bounced up off the roof or ground, output a one-sided panel simply loses.
Two 2 mm panes in an anodised aluminium frame, certified to 5400 Pa of downward load and 2400 Pa of uplift.
Tunnel-oxide passivated contacts give up less output in the first year and keep working in dull, early-morning light.
Tested against salt mist, ammonia and blown sand, with an anti-PID guarantee and an IP68 junction box.
A full-size dual-glass bifacial module built on N-type cells, made for commercial rooftops, carports and ground-mount plants rather than small domestic arrays. The clear rear pane turns light reflected off the surface below into extra production, so a pale membrane or light gravel pays back on every sunny day. Glass on both faces, an anodised aluminium frame and a sealed junction box keep it working through storms, heavy loads and salt-laden coastal air. This model: Module Efficiency 23.3%, Maximum Power (Pmax) 630W.
