Reliance Industries Ltd has become the first company to secure the inclusion of heterojunction (HJT) solar cells in the Approved List of Models and Manufacturers (ALMM) published by the Ministry of New and Renewable Energy, marking a major milestone for India’s solar manufacturing sector. The enlisted cell manufacturing capacity stands at 1,238 MW per year, covering 210 mm × 105 mm formats with zero-busbar designs. The cells are rated with efficiencies of up to 25.6% and power outputs ranging from 5.28 W to 5.66 W.
Reliance’s high-efficiency HJT modules had previously been included in ALMM List-I (modules). The listed module manufacturing capacity is approximately 1,716 MW per year, comprising both monofacial and bifacial glass-to-glass configurations, with power outputs reaching up to 720 Wp.
MNRE has mandated that, from June 1, 2026, all government-backed solar projects must use modules manufactured with cells sourced from the ALMM List-II. Reliance’s integration of HJT cell manufacturing at Jamnagar is a key part of this compliance, ensuring that their modules meet the “domestic content requirement” (DCR) for both cells and modules.
HJT cells produced by Reliance at the Dhirubhai Ambani Green Energy Giga Complex represent a significant upgrade over traditional PERC or TOPCon technologies. The company’ HJT modules feature efficiencies of up to 23.12%, with cell-level roadmaps aiming for even higher efficiencies of up to 26.5% through perovskite-tandem integrations. HJT cells offer a better temperature coefficient (meaning they perform better in high temperature environments) and roughly 25% lower degradation over their lifespan compared to conventional panels.
Reliance Industries Ltd is developing a fully integrated, end-to-end solar manufacturing facility with an initial annual capacity of around 10 GW, with plans to scale this up to 20 GW. In parallel, the company is establishing an integrated battery manufacturing ecosystem, spanning cell production to pack assembly and containerized energy storage systems (ESS), with an initial capacity of 40 GWh, expandable to 100 GWh in subsequent phases.
