Jupiter International expanded its solar cell manufacturing capacity to 3.25 GW from 2 GW after spending ₹550 crore on a new unit at its Baddi campus in Himachal Pradesh.
The Kolkata-based company said Thursday that Unit IV adds 1.25 GW of TOPCon technology capacity. TOPCon, short for tunnel oxide passivated contact, is a cell architecture that delivers higher energy conversion efficiency than older PERC designs and degrades slower over time. The company called the unit a technology step-up that positions it for the market's shift toward performance-led procurement.
“With Unit IV, Jupiter accelerates its transition from scaling capacity to scaling advanced manufacturing capabilities,” the company said in a release.
Chief Executive Officer Dhruv Sharma framed the expansion as a defining step. “By bringing 1.25 GW of TOPCon capacity into production, we are scaling next-generation cell technology that raises the bar on efficiency and long-term performance,” Sharma said. He added that the company is doing this with “a clear focus on manufacturing excellence, sustainability consciousness, and high-skilled job creation.”
