Premier Energies Commissions 7GW Solar Cell Plant in Andhra Pradesh
The ₹3,293-crore Naidupeta facility takes the company to 10.6GW of total solar cell capacity as Indian manufacturers race to build domestic supply chains.
Premier Energies commissioned a 7GW N-type TOPCon G12R solar cell plant in Naidupeta, Andhra Pradesh on Tuesday (2026-09-22). The ₹3,293-crore facility can produce approximately 88,000 solar cells per hour. It raises the company's total solar cell capacity to 10.6GW, the company said.5
Single-facility additions at this scale are uncommon outside China, and the plant's strategic case extends beyond headline gigawatts. Premier Energies said the plant is expected to reach average cell efficiency of approximately 25.8% at full ramp. The company has also announced plans to extend backward integration into ingots and wafers, moving further up a supply chain that Indian manufacturers have broadly relied on imports to fill.5
Competition among Indian solar cell manufacturers has been building through 2026. Jupiter International's joint venture with Ampin Energy Transition began producing its first solar cells in July (2026-07-22), bringing Jupiter's cumulative cell capacity to 4.5GW and its module capacity to 1.5GW, according to Asian Power. Premier Energies now holds more than twice Jupiter's cell capacity following the Naidupeta commissioning, though both are expanding into a market where domestic demand continues to outpace what incumbents can easily serve.4
Manufacturing scale is only as useful as the grid that absorbs what the panels eventually generate. India's transmission infrastructure has lagged behind installation rates. Oilprice.com reported that nearly 40% of solar energy generated in western desert regions in 2025 failed to reach major industrial and population centres due to inadequate grid capacity. Around 4.3GW of installed capacity in areas such as Phalodi and Jaisalmer faces routine daytime curtailment, according to the same report. Curtailed generation earns nothing, regardless of cell efficiency.3
New Delhi is executing a $100-billion programme to expand the national grid by approximately 30% by 2032, Oilprice.com reported. Rajasthan is separately building a 5,000-megawatt battery energy storage system to ease congestion. India also targets more than 100GW of pumped hydro storage by 2047. Those are long-dated commitments, and the gap between when manufacturing capacity comes online and when grid infrastructure catches up is the broader constraint India's solar buildout faces.3
Downstream demand at the project scale is less in doubt. The Khavda Renewable Energy Park is expected to deliver 30GW of combined solar and wind capacity once complete, with utility-scale storage for continuous supply, according to Oilprice.com. A record 511GW of new solar capacity was added globally in 2025, according to The Diplomat, driven partly by panel price declines that have broadened solar's competitiveness against fossil fuels across markets. India's domestic pipeline is substantial enough to sustain offtake for manufacturers operating at Premier Energies' scale.1,2
But global volume creates its own pressure. The 511GW figure reflects sustained investment by Chinese and South-East Asian producers who have operated at industrial scale longer and continue to suppress panel prices. Indian manufacturers competing for export orders, or for domestic projects where imports retain a cost advantage, face that pricing environment whether or not they hold 10GW of domestic cell capacity.2
The backward integration announcement carries more weight than the capacity headline. India has cell and module capacity; it lacks domestic wafer and ingot production at scale. Premier Energies' stated intention to extend into that segment would, if executed, give the company supply chain depth most Indian solar manufacturers do not yet have. Whether it secures financing and begins construction on that upstream expansion before the competitive window narrows is the near-term development to track.5
