Canadian Solar glass-glass bifacial modules - durable, efficient, strong on both sides


Canadian Solar is one of the world's most established PV manufacturers - with over 70 GW of module output delivered. The company's bifacial glass-glass modules combine reliable quality with innovative cell technology. Thanks to the double energy generation via the front and rear sides, they are ideal for flat roofs and ground-mounted systems with a reflective substrate.

With rear side yields of up to 25.9 % in addition to the front side output, the bifacial glass-glass modules from Canadian Solar enable maximum energy yield - especially on reflective substrates. Low annual degradation and a 30-year performance guarantee make them the ideal choice for long-lasting projects with high expected yields.
