As Above Vikram Solar Secures 400 MW Module Supply Order for Agri-Solar Projects in Maharashtra Kolkata, September — Vikram Solar, one of India’s leading solar PV module manufacturers, has secured a 400 MW module supply order from a highly reputed EPC player for a portfolio of decentralised solar projects being developed across multiple locations in Maharashtra. The order further strengthens Vikram Solar’s presence in India’s rapidly expanding agricultural-feeder solarisation segment, which is playing an increasingly important role in the country’s transition towards decentralised and reliable renewable energy infrastructure. Under the agreement, Vikram Solar will supply its high-efficiency N-Type TOPCon G12R modules, featuring glass-to-glass, bifacial technology and half-cut cells, with a power output of 620 Wp. Supplies are scheduled to commence in October 2026. As India continues to accelerate the deployment of solar power, decentralised renewable energy projects are emerging as an important component of the country’s clean energy transition, enabling power generation closer to consumption centres and supporting greater grid resilience. Agricultural feeder solarisation, in particular, is expected to play a critical role in improving energy access for farmers while contributing to India's broader renewable energy and energy-security objectives. Mr. Gyanesh Chaudhary, Chairman & Managing Director, Vikram Solar, said, “Programmes like MSKVY 2.0 represent an important evolution in India’s clean energy journey, bringing the benefits of solar power closer to farmers and agricultural communities. Supplying modules for projects of this scale across Maharashtra reflects the confidence placed in Vikram Solar’s advanced G12R TOPCon technology and our ability to support large, geographically distributed solar deployments. As India continues to expand its renewable energy infrastructure, we remain committed to delivering high- performance solar solutions that support energy security, strengthen domestic manufacturing and contribute meaningfully to the country’s clean energy ambitions.” For Vikram Solar, the order reflects the company’s growing ability to serve large-scale and geographically distributed solar programmes, supported by its expanding manufacturing footprint and advanced technology portfolio.
