Jupiter International Expands Solar Cell Manufacturing Capacity to 3.25 GW with New 1.25 GW TOPCon Solar Cell Facility

By Editorial Team Last updated Jun 30, 2026

STORY SYNOPSIS

Jupiter International has inaugurated a 1.25 GW TOPCon solar cell manufacturing facility at its Baddi campus in Himachal Pradesh, expanding its total solar cell production capacity to 3.25 GW. The new unit strengthens the company’s capabilities in high-efficiency solar cell manufacturing, supporting India’s growing demand for advanced photovoltaic technologies and reinforcing its position in domestic solar manufacturing.

Jupiter International Limited, one of India’s leading solar cell manufacturers, has inaugurated its Unit IV at its Baddi manufacturing campus in Himachal Pradesh, adding 1.25 GW of TOPCon (Tunnel Oxide Passivated Contact) solar cell manufacturing capacity and expanding its total solar cell manufacturing capacity from 2 GW to 3.25 GW.

Unit IV marks a significant technology step-up for Jupiter International, strengthening its ability to deliver next-generation, high-efficiency solar cells at scale as the market increasingly shifts toward higher efficiency benchmarks and performance-led procurement.

This milestone builds on Jupiter’s recent expansion at Baddi, where the company added 1 GW of mono PERC solar cell manufacturing capacity earlier this year, taking its total installed capacity to nearly 2 GW. TOPCon technology is widely regarded as the next phase of mainstream solar cell manufacturing, offering higher efficiency potential and improved long-term performance. With Unit IV, Jupiter accelerates its transition from scaling capacity to scaling advanced manufacturing capabilities.

“Commencement of production at Unit IV baddi will be a defining step in Jupiter’s technology journey. 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. We are doing this with a clear focus on manufacturing excellence, sustainability consciousness, and high-skilled job creation. It provides a technology platform on which jupiter is scaling up to build a 3 GW TopCon ++ performance fab to be commissioned in Nagpur at the end of the year” — Dhruv Sharma, Chief Executive Officer, Jupiter International Limited

The ramp-up of Unit IV has been anchored in a quality-first, sustainability-conscious manufacturing approach, supported by disciplined process controls and manufacturing systems designed for consistent output at scale. The expansion is also expected to strengthen local economic impact in Himachal Pradesh, supporting a growing pipeline of high-skilled green jobs across production, process engineering, automation, quality, maintenance and EHS—backed by structured training and capability building.

With the Unit IV, Jupiter International continues to deepen its role in India’s clean energy transition by strengthening domestic solar cell capability and accelerating high-efficiency technology adoption at scale.
