As Above Vikram Solar Strengthens DCR Market Position Through Domestic Cell Pact of 1 GW with Avaada Electro Kolkata, 15th September: Vikram Solar, a pioneer in Indian solar module manufacturing, has entered into a domestic cell supply agreement with Avaada Electro, reinforcing its foothold in India’s fast- expanding Domestic Content Requirement (DCR) segment and strengthening long-term supply-chain resilience. Under the agreement, Avaada Electro will supply 1 GW of ALMM-compliant domestically manufactured half-cut N-Type G12R TOPCon solar cells for Vikram Solar’s module manufacturing operations. Deliveries are scheduled to commence in September 2026, ensuring consistency in supply and operational continuity to meet the country's growing DCR requirements. This agreement marks a further step in Vikram Solar's penetration of the domestic DCR market and its strategy to diversify and strengthen its cell supply chain, adding to the supply agreements the company has entered into earlier this year. It also complements Vikram Solar's backward integration strategy, anchored by its upcoming 9 GW high-efficiency solar cell manufacturing facility, scheduled to commission in Q4 FY27. Mr. Gyanesh Chaudhary, Chairman & Managing Director, Vikram Solar, said: "The next phase of India's solar growth will be won or lost on supply chain depth, not just manufacturing scale. This arrangement is another step in that direction- one that widens our supplier base, strengthens our hand on DCR, and gives us the confidence to commit to India's energy security with fewer variables outside our control. Atmanirbhar Bharat won't be built by any single partnership; it'll be built by companies that keep making these choices, year after year.” About Vikram Solar Limited: Vikram Solar Limited is one of the leading Indian solar module manufacturers, specializing in efficient photovoltaic (PV) module manufacturing, with an international presence across 39 countries.
