Premier Energies: Limited has commissioned its 7 GW N-type TOPCon G12R solar cell manufacturing facility at Naidupeta, Andhra Pradesh, and begun trial runs. The new facility takes the company’s total solar cell manufacturing capacity to 10.6 GW, making it India’s largest solar cell manufacturing capacity. Spread across 101 acres, the facility has been developed at a capital expenditure of ₹3,293 crore. Premier Energies said the plant was commissioned on schedule and within the planned budget.
Chiranjeev Saluja, Managing Director, Premier Energies Limited, said, “Commissioning India’s largest solar cell manufacturing facility on time and within budget is an important execution milestone for Premier Energies. We remain positive on the outlook for orders, pricing and demand for high-efficiency solar products. The timing of this 7 GW capacity addition is therefore significant: as the line stabilises and ramps up, it gives us the scale to serve that demand with greater supply reliability and operating efficiency. 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.”
The Naidupeta plant is designed for high-throughput manufacturing and can produce approximately 88,000 solar cells per hour. Digital systems and artificial intelligence are being used for predictive performance analysis, process control and precision manufacturing. Automated transport, packing and packaging systems are also designed to improve production efficiency and consistency.
The facility uses N-type TOPCon G12R technology and has been designed to accommodate future upgrades to next-generation TOPCon+ technologies, including poly-finger metallisation and advanced edge-isolation processes. Following stabilisation and ramp-up, the plant is targeting average solar cell efficiency of approximately 25.8%.
Sudhir Reddy, Director & Chief Strategy Officer, Premier Energies Limited, said, “Naidupeta plant is a major step forward in our integrated manufacturing roadmap. The combination of scale, automation and advanced cell technology is designed to improve manufacturing competitiveness, strengthen supply-chain resilience and position Premier Energies to address demand for high-efficiency solar products in India and international markets.”
The plant also incorporates a Zero Liquid Discharge (ZLD) system designed to maximise water recycling and reuse. The company said the facility will support growing demand for high-efficiency solar products in domestic and international markets. Premier Energies is implementing a ₹12,500 crore capital expenditure programme over three years to more than double its solar manufacturing capacity. The programme also includes backward integration into ingots and wafers and expansion into inverters, transformers and battery energy storage systems. With 30 years of experience in solar manufacturing, Premier Energies has operations spanning solar cells and modules and is expanding its manufacturing and technology capabilities as part of its growth strategy.
