Alpex Solar Ltd has announced plans to upgrade its upcoming solar cell production facility at Kosi Kotwan from PERC to high-efficiency G12R TOPCon with a capacity of 2.2 GW. With this, the company will be among the nation’s first to produce high-efficiency G12R cells. The expansion will be executed in two phases: a 1.4 GW phase becoming operational in Q1 of FY26-27, followed by the remaining 800 MW within six months.
This additional project cost of around INR 136 crore, due to the upgraded TOPCon technology and enhanced capacity, will be met entirely through internal accruals. This new facility is designed to secure long-term profitability and avoid the disruptive costs of a future upgrade.
“This decisive move positions Alpex Solar at the forefront of India’s solar manufacturing landscape, ensuring its product offering meets accelerating global demand and aligning its output with its 3.6 GW module capacity and the upcoming ALMM List 2 mandate,” stated the company. “By adopting a direct-to-TOPCon strategy, Alpex Solar avoids the costly and disruptive need to later shut down the factory for a PERC-to-TOPCon upgrade. This preemptive action mitigates potential future revenue loss and factory downtime, safeguarding profitability and ensuring continuous operation.”
