Emmvee introduces 545 W glass-to-glass bifacial solar module


Karnataka-based Emmvee has unveiled Sapphire series glass-to-glass bifacial modules at Renewable Energy India Expo 2022. The modules are available in power outputs ranging from 530 W to 545 W, with conversion efficiencies between 20.52% and 21.10% under standard temperature conditions. At low irradiance (200 W/m2, 25 degree Celsius and AM1.5), the module is claimed to yield at least 95% of its STC efficiency. Open-circuit voltage is 49.2-49.75 V, and short-circuit current is 13.56 A to 13.88 A.

Each module is built with 144 mono PERC half cells and ten busbars. It weighs 2,278 mm x 1,134 mm x 35 mm and weighs 30 kg. The modules come with a 12-year product warranty and a 30-year linear performance warranty. The degradation in the first year is purportedly 2.0%, and the 30-year end power output is guaranteed to be no less than 84.95% of the nominal output power.

Currently, Emmvee has 1.25 GW of module capacity in Karnataka. “We are adding another 2 GW of modules capacity with 1.5 GW of mono PERC and TopCon cell capacity at our existing manufacturing site. This capacity will become operational by December 2023,” Suhas Donthi, director-Sales and Operations at Emmvee India, told pv magazine.
