Bifacial PV module generates power from both front and back

Solar photovoltaic modules specialist Trina Solar has launched its high-efficiency bifacial module DUOMAX Twin, an innovative module design integrating the technology of the company's high-efficiency bifacial PERC cell and the dual-glass DUOMAX module.

DUOMAX Twin generates power from both the front and back sides of the solar module and performs well even under weak light conditions — the front side receives direct sunlight while the back side receives reflected and scattered light. Compared with traditional single-sided modules, the DUOMAX Twin can deliver as much as 25 per cent additional energy yield.

This new module enables increased energy density and higher output, while maintaining development costs at a comparable level as for standard modules. By maximising energy generation, the DUOMAX Twin can significantly reduce levelised cost of electricity (LCOE). Since bifacial modules absorb solar radiation from both sides, they allow a variety of tilt and installation options and are ideal for elevated ground, rooftop, desert and snowy area installations or on-water applications — and the dual-glass design used in all DUOMAX panels provides extreme durability even in the harshest environments.
