Premier Energies Ltd has commissioned a 7 GW solar cell manufacturing facility in Naidupeta, Andhra Pradesh, taking its total solar cell manufacturing capacity to 10.6 GW and making it India’s largest solar cell manufacturer by capacity.
The new facility, which has begun trial production, will manufacture n-type TOPCon G12R solar cells.
The facility was commissioned on schedule and within budget, according to the company. Following stabilisation and ramp-up, the facility is targeting average solar cell efficiency of approximately 25.8%.
Spread across 40 hectares, the facility is India’s largest solar cell manufacturing plant. It was developed at a capital expenditure of INR 3,293 crore ($343.7 million). The digitally enabled plant is designed to produce around 88,000 solar cells per hour.
According to the company, the facility is designed to be future-ready, with potential upgrades to next-generation TOPCon technologies, including poly-finger metallisation and advanced edge-isolation processes.
“Commissioning India’s largest solar cell manufacturing facility on time and within budget is an important execution milestone for Premier Energies,” said Chiranjeev Saluja, Managing Director, Premier Energies Ltd. “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.”
Saluja said the cell capacity addition, together with the company’s planned backward integration into ingots and wafers, strengthens the company’s strategy of building a fully integrated and globally competitive solar manufacturing platform while supporting India’s clean energy transition.
Advanced digital systems and artificial intelligence support predictive performance analysis, tighter process control and precision manufacturing at the facility, while fully automated transport, packing and packaging systems improve throughput, consistency and operating efficiency.
The commissioning strengthens Premier Energies’ ability to serve growing demand for high-efficiency solar products across domestic and international markets.
Sudhir Reddy, director & chief strategy officer, Premier Energies Limited, added: “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 facility employs a Zero Liquid Discharge (ZLD) system to maximise water recycling and reuse, reinforcing Premier Energies’ focus on responsible resource management and sustainable manufacturing.
Premier Energies Ltd, one of India’s largest integrated solar manufacturers, is undertaking an INR 12,500 crore capital expenditure programme over three years to more than double its solar manufacturing capacity, expand backward integration into ingots and wafers, and diversify into inverters, transformers and battery energy storage systems.
