Kolkata, June 25, 2026: Leading Indian solar cell manufacturer Jupiter International Limited has inaugurated Unit IV at its Baddi manufacturing facility in Himachal Pradesh, adding 1.25 GW of TOPCon (Tunnel Oxide Passivated Contact) solar cell manufacturing capacity and increasing its total installed capacity from 2 GW to 3.25 GW.
The new facility marks a major technological milestone for the company as it strengthens its position in the rapidly growing high-efficiency solar cell market. With the launch of Unit IV, Jupiter International is moving beyond capacity expansion and accelerating its transition toward advanced solar manufacturing capabilities.
TOPCon technology is widely recognized as the next generation of mainstream solar cell manufacturing, offering higher energy conversion efficiency and superior long-term performance compared to conventional technologies.
The development comes shortly after Jupiter International expanded its Baddi operations with an additional 1 GW Mono PERC solar cell manufacturing line earlier this year. The latest expansion further reinforces the company’s commitment to supporting India’s renewable energy ambitions through domestic manufacturing.
Speaking on the occasion, Dhruv Sharma, Chief Executive Officer of Jupiter International, said the commencement of production at Unit IV represents a defining moment in the company’s technology journey. He noted that the new TOPCon capacity will enable Jupiter to scale next-generation solar technologies while maintaining a strong focus on manufacturing excellence, sustainability, and skilled job creation.
The company also highlighted that the expansion is expected to generate significant employment opportunities in Himachal Pradesh across production, process engineering, automation, quality control, maintenance, and EHS functions, supported by structured training and workforce development programs.
Why it matters: The launch of the 1.25 GW TOPCon facility strengthens India’s domestic solar manufacturing ecosystem and positions Jupiter International as a key player in the country’s transition toward high-efficiency, next-generation solar energy solutions.
