Energetica India Magazine - November 2025

While last year, capacity enhancement announcements dominated the chatter, this REI focus was on improving module efficien - cy in addition to enhancing capacity at upstream components like solar cells, ingots and wafers. In that direction, the launch of solar PV modules based on G12R TOPCon technology by major solar module manufacturers raises benchmarks in technology and quality. G12R TOPCon Dominates Module Launches GREW Solar launched its G12R High-Power Series, delivering up to 635 Wp. The module is engineered for utility-scale efficiency, cutting total module count by 6-8 percent per MW, reducing BOS costs, and improving logistics and installation timelines. With an optimised cell layout and enhanced mechanical strength, it offers 6-7 percent higher container power density and 1.5-3 per- cent more power per m³ compared to standard TOPCon modules. Emmvee introduced its Titanium Duo G12 n-type glass-glass bifacial TOP- Con module, delivering a power output of 715 Wp and efficiency of 23.18 percent. The module features 132 half-cut TOPCon cells (210x105 mm) and offers up to 85 percent bifaciality, enabling higher energy yield. It comes with a temperature coefficient of -0.29 percent per degree centigrade and operates between -40°C and 85°C. The module uses 2 mm semi-tempered glass on both sides, ensuring durability and enhanced performance under varied climatic conditions. Gautam Solar launched 635 Wp and 640 Wp G12R TOPCon solar modules. The modules offer up to 23.69 percent efficiency. Featuring 132 rectangular cells, these high-wattage modules are almost similar in size as compared to standard TOPCon modules and deliver approximately five percent higher power genera - tion compared to them. With minimal LID and LeTID, lower degradation rates, and bifacial gain po- tential of up to 30 percent, the 635 and 640 Wp G12R ensure enhanced long- term energy yield, durability, and reliability. “These modules’ superior power density allows for greater energy output using less installation space, making them ideal for rooftop and utility-scale solar projects,” the company stated. Insolation Energy (INA Solar) launched its new n-type TOPCon G12R bifa- cial glass-glass solar modules, delivering 610–635 Wp of power with efficien - cies above 22 percent. The company announced that commercial production of G12R solar cells will commence by September 2026, with an initial capacity of 4.5 GW under Phase 1. INA Solar also plans to expand its manufacturing foot- print and pursue backward integration into ingot and wafer production, aiming for complete vertical integration across the solar value chain. energetica INDIA- November_2025 31 EVENT COVERAGE
