Premier Energies Limited has commissioned its 7 GW N-type TOPCon G12R solar cell manufacturing facility at Naidupeta, Andhra Pradesh, and commenced trial runs. The addition takes the company’s total solar cell manufacturing capacity to 10.6 GW, making Premier Energies India’s largest solar cell manufacturer by capacity. Spread across 101 acres, the facility has been developed with a capital investment of ₹3,293 crore and is positioned as India’s largest solar cell manufacturing plant.
Commenting on the development, Mr. 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.”
Designed for high-throughput, digitally enabled manufacturing, the facility has the capacity to produce approximately 88,000 solar cells per hour. Advanced digital systems and artificial intelligence enable predictive performance analysis, enhanced process control and precision manufacturing, while automated material handling, transport, packing and packaging systems are designed to improve throughput, consistency and overall operational efficiency.
The commissioning significantly increases Premier Energies’ manufacturing scale and reinforces its position as India’s largest solar cell manufacturer by capacity. The expanded footprint also strengthens the company’s ability to meet growing domestic and international demand for high-efficiency solar products while improving supply reliability and manufacturing efficiency.
Mr. 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 7 GW facility has been designed with a future-ready architecture that allows for upgrades to next-generation TOPCon+ technologies, including poly-finger metallization and advanced edge-isolation processes. Once the plant stabilizes and reaches full ramp-up, it is expected to achieve an average solar cell efficiency of approximately 25.8%.
The facility also incorporates a Zero Liquid Discharge (ZLD) system designed to maximize water recovery, recycling and reuse. The system supports Premier Energies’ efforts to optimize resource utilization and strengthen sustainable manufacturing practices across its operations.
