India module capacity hits 233 GW amid 35-40% utilization

India’s solar module manufacturing capacity has reached 233 GW as of June 2026, according to data reported by pv magazine. This figure stands in contrast to the country’s annual domestic demand, which is estimated at 30 GW to 40 GW. The disparity between installed capacity and consumption results in a production line utilization rate of just 35% to 40%.

Utilization Gap

Industry benchmarks suggest that solar module plants require a utilization rate between 50% and 65% to operate sustainably. Current Indian production lines, running at only 35% to 40%, fall short of this lower bound.

Supply Chain Imbalance

• Module capacity stands at 7 times the installed cell capacity.
• Module capacity is 116 times the combined ingot and wafer capacity.
• Polysilicon, solar glass, and bill of materials manufacturing remain in limited development.

Policy and Market Views

Dilip Mehta, director, technical services at Hexa Climate, emphasized that the core challenge lies not merely in module production volume, but in how it aligns with the broader supply chain. Bondada Raghavendra Rao, chairman and managing director at Bondada Group, argued that future growth must be tightly synchronized with genuine demand, active project pipelines, and the maturation of the entire solar value chain. Ankit Singhania, director at Navitas Solar, observed that the route to vertical integration does not have to follow a uniform model for all manufacturers.

Vinay Rustagi, chief business officer at Premier Energies, maintained that regulatory intervention is superfluous, as market dynamics will inherently correct any discrepancies over time. Sourabh Kumar, vice president–strategic investments at Ampin Energy Transition, warned that committing substantial capital to technologies that lose commercial viability within a short span could pose a greater risk than a lack of capacity.

This regulatory framework has applied to modules since 2021. It will extend to cells beginning in June 2026, and to wafers and ingots by 2028. For wafers to qualify for listing, a minimum of three independent manufacturing facilities, free from common ownership, must be active. These units must collectively possess an annual capacity of at least 15 GW, matched by equivalent ingot capacity. Premier Energies recently commissioned one of India’s

Upstream Investment Criteria and Integration Strategies

Sourabh Kumar, vice president–strategic investments at Ampin Energy Transition, detailed the benchmarks used to evaluate new production facilities. These include determining if the technology will stay competitive over a five-to-seven-year horizon, assessing the plant's capacity to reach scale with high utilization rates, and verifying that the output can rival imports on a delivered-cost basis. He stressed that producers need robust balance sheets to endure stretches of reduced margins. Dilip Mehta from Hexa Climate argued that for independent module makers, moving into cell production is a more feasible upstream move compared to ingot and wafer fabrication, which demand heavy capital, significant power, and involve a prolonged learning curve. Mehta proposed strategies like backward integration into cells, securing long-term contracts with local cell producers, or merging with vertically integrated firms. Ankit Singhania, a director at Navitas Solar, observed that firms may mix organic investments, strategic alliances, joint ventures, and extended sourcing deals based on their size and strategic goals. The Approved List of Models and Manufacturers (ALMM) rule, which requires government-supported projects to source components from vetted domestic suppliers, has been in effect for modules since 2021.

ALMM Wafer Thresholds and Upstream Sequencing

Dilip Mehta, director, technical services at Hexa Climate, noted that this regulatory timeline creates a specific window for upstream investment, though first movers carry the associated risks. Meanwhile, Vinay Rustagi, chief business officer at Premier Energies, which recently commissioned a major cell facility in Naidupeta, Andhra Pradesh, argued that market signals will automatically correct imbalances without government intervention.
