Premier Energies Ltd, one of India’s largest integrated solar manufacturers, today announced the launch of its next-generation 620 W DCR solar module based on n-type tunnel oxide passivated contact (TOPCon) cells. The module’s power conversion efficiency is 22.95%.
The module is built with 132 half-cut bifacial cells based on G12R (210×182.3 mm) rectangular wafer format, offering an enhanced output with bifaciality of up to 85%.
“With the introduction of TOPCon architecture, the G12R 620 W module delivers exceptional power density, an improved temperature coefficient, and stronger low-light performance. The rectangular G12R n-type cell format unlocks higher string power and BOS optimization, making it ideal for utility-scale, commercial, and industrial rooftop projects,” stated the company.
The module features an open-circuit voltage of 49.34 V and a short-circuit current of 15.63 A. Pmax temperature coefficient is -0.29% per degree celcius.
The modules measure 2,382 mm x 1,134 mm x 35 mm.
Chiranjeev Saluja, managing director and chief executive officer, Premier Energies, said, “As one of the first few companies to bring 620 W DCR modules to market, we are offering a future-ready solution to help solar power investors and consumers in extracting more energy and value from every ray of the sun. These modules, compliant with India’s Domestic Content Requirement (DCR) regulations, go a long way in supporting the country’s solar power ambitions and Make in India policy.
