Jupiter International Inaugurates 1.25 GW TOPCon Solar Cell Unit in Baddi, Expands Total Capacity to 3.25 GW

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 solar cell production capacity.

With this addition, the company’s total solar cell manufacturing capacity has increased from 2 GW to 3.25 GW, marking a significant expansion in its advanced solar technology portfolio.

The new facility focuses on TOPCon (Tunnel Oxide Passivated Contact) technology, which is widely considered the next-generation standard in solar cell manufacturing due to its higher efficiency and improved long-term performance compared to conventional technologies.

The expansion follows Jupiter International’s earlier addition of 1 GW mono PERC capacity at the same Baddi campus, further strengthening its transition toward high-efficiency solar manufacturing.

According to the company, Unit IV represents a key milestone in its technology roadmap, enabling the scaling of next-generation solar cells while maintaining a focus on manufacturing quality, sustainability, and operational excellence.

Jupiter International also highlighted that the expansion will contribute to local economic development in Himachal Pradesh by generating skilled employment opportunities across production, engineering, quality control, automation, maintenance, and EHS functions, supported by structured training programmes.

The company further noted that the new capacity will support its broader plan to develop a 3 GW TOPCon++ manufacturing facility in Nagpur, which is expected to be commissioned later this year.

With this development, Jupiter International continues to strengthen India’s domestic solar manufacturing ecosystem and accelerate the adoption of high-efficiency solar technologies in the clean energy transition.
