The project has an estimated cost of approximately ₹1,000 crore, with Solarworld's commitment of up to ₹420 crore. Commercial production is targeted to commence by June 2027. The proposed facility marks an important step towards strengthening the Company's manufacturing capabilities and advancing its integrated clean energy strategy. The Company successfully commissioned its 50 MW AC solar project in Assam and received charging permission for its 200 MW AC / 272 MW DC Khavda project in Gujarat. These developments reflect continued progress across its project portfolio and execution capabilities in key renewable energy markets. The Company continued to broaden its clean energy offerings with the launch of LFP-based home energy storage batteries, a 2,500 kVA central power conversion system developed in collaboration with Belectriq, and AQUILA bifacial G12 solar modules with capacities of up to 715 Wp. These additions strengthen Solarworld's capabilities across power generation, conversion and storage, enabling it to address a wider range of residential, commercial and utility-scale requirements. As part of its broader growth strategy, the Company is in discussions with global players for a potential technical collaboration to enter the Data Centre EPC segment. This initiative reflects Solarworld's intent to explore opportunities in adjacent infrastructure segments and leverage its existing engineering and project execution capabilities. The Company currently has a solar project portfolio of over 1.5 GW and a BESS EPC and IPP portfolio exceeding 1.2 GW, reflecting its growing presence across the clean energy value chain. Management Commentary Commenting on the performance and business developments, Mr Kartik Teltia, Managing Director, Solarworld Energy Solutions Limited, said: “India's clean energy landscape is evolving beyond capacity additions towards the development of an integrated ecosystem spanning manufacturing, power conversion and energy storage. As the sector scales, the ability to offer solutions across these interconnected segments will become increasingly important. Our proposed solar cell manufacturing joint venture is a significant step towards strengthening our backward integration and building greater depth across the solar value chain. Alongside this, our expanding product portfolio and progress across project execution reflect our focus on addressing the changing requirements of the market.
