Jupiter International Starts Producing 1.25 GW of TOPCon Solar Cells

News Desk, News Nation 360: Jupiter International Limited, a prominent solar cell manufacturer with headquarters in Kolkata, has formally opened its state-of-the-art Unit IV at its Baddi manufacturing campus in Himachal Pradesh, adding 1.25 GW of high-efficiency TOPCon (Tunnel Oxide Passivated Contact) solar cell production capacity. At a time when next-generation TOPCon modules are quickly emerging as India's primary procurement benchmark, this historic commissioning successfully expands the company's total domestic solar cell manufacturing capacity from 2 GW to a formidable 3.25 GW, filling a critical supply gap for project developers. Unit IV moves Jupiter from basic volume scaling to high-end, advanced tech performance, building on a previous 1 GW mono-PERC brownfield expansion completed at the same Solan district campus earlier this year. As the same high-skilled manufacturing platform that Jupiter is currently scaling up to build a massive 3 GW TOPCon++ performance fab in Nagpur, which is scheduled for commissioning by the end of 2026, Dhruv Sharma, Chief Executive Officer of Jupiter International Limited, highlighted that this rollout represents a pivotal step in the company's technology roadmap. The capital-intensive infrastructure boost, supported by structured capability-building programs and disciplined quality controls, is set to accelerate India's clean energy transition while simultaneously boosting the local Himachali economy through the long-term creation of specialised green jobs in engineering, environmental health and safety (EHS), and process automation.
