Jupiter International Commissions 1.25 GW TOPCon Solar Cell Manufacturing Unit, Boosts Total Capacity to 3.25 GW

Jupiter International Expands Solar Cell Manufacturing with 1.25 GW TOPCon Facility

Jupiter International Limited has commissioned a 1.25 GW Tunnel Oxide Passivated Contact (TOPCon) solar cell manufacturing unit at its manufacturing campus in Baddi, Himachal Pradesh, marking a significant milestone in India's rapidly expanding domestic solar manufacturing sector. The new facility, inaugurated as Unit IV, increases the company's total solar cell manufacturing capacity from 2 GW to 3.25 GW.

The company has invested approximately ₹550 crore in developing the advanced manufacturing unit, which will produce next-generation, high-efficiency TOPCon solar cells. The commissioning reflects Jupiter International's strategic shift toward advanced photovoltaic technologies amid rising demand for high-performance solar components in India and overseas.

Strengthening India's Solar Manufacturing Ecosystem

The newly operational TOPCon production line complements Jupiter International's existing 2 GW monocrystalline PERC solar cell manufacturing facility at the Baddi campus. With the addition of the new line, the company is well-positioned to cater to the growing demand for high-efficiency solar cells driven by utility-scale, commercial, and rooftop solar projects.

TOPCon technology has emerged as one of the preferred cell technologies globally due to its superior energy conversion efficiency, improved temperature performance, and lower degradation compared to conventional PERC cells. As India's solar market increasingly transitions toward advanced technologies, domestic production of TOPCon cells is expected to reduce import dependence while improving supply chain resilience.

Supporting India's Clean Energy Goals

The expansion comes at a time when India is aggressively scaling domestic manufacturing under various government initiatives aimed at building a self-reliant solar supply chain. Industry experts have highlighted a shortage of domestically manufactured TOPCon cells, making Jupiter International's capacity addition a timely boost for project developers and module manufacturers.

According to the company, the commissioning of Unit IV represents more than just a capacity expansion—it signifies its transition toward manufacturing advanced solar technologies that can support India's long-term renewable energy ambitions and strengthen its position in the global photovoltaic value chain.

Industry Outlook

India's solar manufacturing sector has witnessed significant investments over the past few years as manufacturers expand capacities across cells and modules to meet domestic demand and capitalize on export opportunities. Advanced technologies such as TOPCon are expected to dominate new manufacturing additions as developers seek higher efficiency and improved lifecycle performance.

With its latest investment, Jupiter International joins the growing list of Indian manufacturers expanding next-generation solar cell production, reinforcing the country's ambition to become a global hub for photovoltaic manufacturing.
