Premier Energies Commissions 7 GW TOPCon Solar Cell Plant in Andhra Pradesh

Premier Energies has commissioned a 7 GW solar cell manufacturing facility in Naidupeta, Andhra Pradesh, taking the Hyderabad-headquartered company's total cell capacity to 10.6 GW and making it one of the largest solar cell producers in India by a wide margin.

Inside the new line

The Naidupeta plant runs on N-type tunnel oxide passivated contact (TOPCon) G12R technology, the higher-efficiency cell architecture that is rapidly displacing older PERC lines across the Indian solar industry. Premier says the facility is capable of producing roughly 88,000 solar cells an hour and has been built with digital process controls and AI-assisted predictive maintenance baked in from the start, along with headroom to upgrade to next-generation TOPCon+ processes such as poly-finger metallisation without a full line rebuild. The 101-acre facility also includes a Zero Liquid Discharge water-recycling system, and Premier is targeting average cell efficiencies of around 25.8% once the line is fully ramped.

The plant represents a capital outlay of about ₹3,293 crore (roughly $343 million) and was commissioned on September 21, 2026, as part of a three-year, roughly ₹12,500 crore ($1.3 billion) expansion programme the company has been executing across cells, modules, wafers and batteries.

Part of a bigger build-out

Naidupeta doesn't stand alone. Premier Energies inaugurated a separate 5.6 GW module facility in Telangana in July 2026, and has additional plans in motion for a 10 GW ingot-and-wafer plant, 6 GWh of battery-storage manufacturing capacity, and 18,000 metric tonnes a year of aluminium-frame production — the frames that hold finished modules together. Taken together, the strategy is vertical integration: rather than buying wafers and cells on the open market and assembling modules, Premier is building capacity at every major step of the solar value chain, insulating itself from the import dependence that has periodically squeezed Indian module makers on cell and wafer supply.

That insulation matters more than usual right now. India's solar manufacturing base has been expanding module capacity faster than cell capacity for several years, and industry trackers have flagged a growing cell-supply shortage as the sector's most pressing near-term bottleneck — module lines sitting idle or running below capacity because there simply aren't enough domestically-made cells to feed them. A large new TOPCon cell line from an already-established manufacturer directly addresses that gap rather than adding to the module glut.

Company backdrop

Premier Energies, founded in 1995 and listed on Indian stock exchanges, has reported 35% year-on-year revenue growth in the first quarter of its current fiscal year, underlining that the expansion push is backed by growing order volumes rather than being a speculative capacity bet. The company's existing footprint already spans solar wafers, cells, modules and EPC (engineering, procurement and construction) services for utility-scale solar projects, giving Naidupeta's output a captive downstream market within Premier's own module and project business even before third-party sales are counted.

Why TOPCon, specifically

TOPCon cells improve on older PERC (passivated emitter and rear cell) technology by adding a thin tunnel-oxide layer that reduces electron recombination losses at the cell's rear surface, typically lifting conversion efficiency by one to two percentage points. That may sound marginal, but at gigawatt scale it translates into meaningfully more electricity generated per rupee of land, mounting hardware and inverter capacity deployed — which is why TOPCon has become the default choice for new solar cell capacity in India over the past two years, including in this facility.

What to watch

The near-term question is ramp speed: whether Naidupeta reaches its full 88,000-cells-per-hour run rate quickly enough to meaningfully ease the domestic cell shortage industry trackers have been flagging through 2026, or whether demand from Premier's own module lines and long-term supply contracts absorbs most of the new output before it reaches the open market. The pace at which the parallel 10 GW ingot-and-wafer plant comes online will also matter — cell capacity is only as useful as the wafer supply feeding it, and India's wafer manufacturing base remains thinner than its cell and module capacity.
