Premier Energies has commissioned a 7 GW n-type TOPCon cell factory in Andhra Pradesh
Its total solar cell production capacity expands to 10.6 GW, making it the largest Indian solar cell manufacturer, claims the company
The factory is targeting average cell efficiency of around 25.8% after stabilization and ramp-up
Indian solar PV manufacturer Premier Energies has commissioned what it describes as India’s largest solar cell manufacturing facility. The n-type TOPCon G12R factory has an annual production capacity of 7 GW.
Located in Naidupeta, Andhra Pradesh, the facility spans 101 acres and was built at an investment of INR 3,293 crore. Chiranjeev Saluja, Managing Director of Premier Energies, said the Naidupeta factory was commissioned on time and within budget.
With the new facility now operational, Premier Energies says its total solar cell manufacturing capacity has reached 10.6 GW, including its existing 3.6 GW capacity, making it India’s largest solar cell manufacturer.
The company says the new fab is designed to produce close to 88,000 solar cells per hour and is equipped with advanced digital systems, artificial intelligence, predictive performance analysis, and precision manufacturing. It is also equipped with a Zero Liquid Discharge (ZLD) system to maximize water recycling and reuse, boosting the factory’s sustainable manufacturing credentials.
Once factory stabilization and ramp-up are complete, Premier Energies expects to target an average solar cell efficiency of approximately 25.8%.
The factory is also designed to be future-ready, accommodating potential upgrades to next-generation TOPCon+ technologies, including poly-finger metallization and advanced edge-isolation processes.
With this expansion, the manufacturer is eyeing domestic and international demand for high-efficiency solar products. As of June 30, 2026, Premier Energies reported an order book worth INR 150 billion with a 100% domestic share, led by cells at 58%, followed by modules at 40%.
Premier Energies’ solar module production capacity had reached 11.1 GW as of June 2026. It is now planning to expand with 10 GW of ingot-wafer capacity, 18,000 MT of aluminum frames, and 12 GWh of battery energy storage systems (BESS) capacity (see Premier Energies Q1 FY27 Profit Rises 53% YoY As Orders Grow).
“Together with our planned backward integration into ingots and wafers, this strengthens our strategy of building a fully integrated and globally competitive solar manufacturing platform while supporting India’s clean energy transition,” added Saluja.
