Spread across 101 acres and developed at a capital expenditure of INR 23,293 crore, the facility is India's largest solar cell manufacturing plant to date, claimed the company.
Commenting on the development, Chiranjeev Saluja, Managing Director, Premier Energies, 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.”
Built for high-throughput, digitally enabled manufacturing, the facility can produce approximately 88,000 solar cells per hour. Advanced digital systems and artificial intelligence support predictive performance analysis, tighter process control and precision manufacturing, while fully automated transport, packing and packaging systems improve throughput, consistency and operating efficiency, the company stated.
Sudhir Reddy, Director and Chief Strategy Officer, Premier Energies, 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 7 GW plant is designed to be future-ready, with potential upgrades to next-generation TOPCon+ technologies, including poly-finger metallisation and advanced edge-isolation processes. Following stabilisation and ramp-up, the facility is targeting an average solar cell efficiency of approximately 25.8 percent, the company said, adding that a Zero Liquid Discharge (ZLD) system has been designed to maximise water recycling and reuse.
