India’s solar module manufacturing capacity has surged past 200 GW by August 2026, marking a massive shift from earlier years. However, the sector remains 100% dependent on imports for critical raw materials like polysilicon. This gap creates supply chain risks and cost pressures that the government aims to address through new incentive schemes for domestic manufacturing.
India’s solar energy sector has reached a major milestone as of August 2026, with solar module manufacturing capacity crossing the 200 gigawatt (GW) mark. This expansion is a significant step from just a few years ago when domestic production capacity was minimal. The country has also seen its total installed solar power reach approximately 164.59 GW, reflecting the country's aggressive push toward renewable energy and the transition away from fossil fuels.
However, this growth in assembly capacity hides a deeper challenge. While India can now assemble a high volume of solar modules, the country still depends entirely on imports for polysilicon—a primary raw material needed to create solar cells. Additionally, there is a heavy reliance on imported wafers and ingots, with most of these supplies sourced from China. This creates a structural gap where domestic manufacturers are essentially assembly hubs rather than integrated producers, leaving them vulnerable to global price fluctuations, shipping delays, and geopolitical tensions.
To bridge this gap, the government has introduced policies such as the Approved List of Models and Manufacturers (ALMM), which mandates that solar projects use domestically manufactured cells. The government is also planning a new incentive scheme to encourage the local production of polysilicon, with an aim to reach 30 GW of capacity by 2030. This initiative is expected to require investments of roughly ₹25,000 crore, aiming to move the industry from simple assembly toward true backward integration.
For the solar industry, this transition presents both risks and opportunities. The reliance on imported upstream materials means that if global prices for polysilicon or wafers rise, domestic manufacturers may see their profit margins come under pressure. Furthermore, there is the risk of execution delays for the new incentive schemes, which could slow down the move toward local manufacturing. Investors and industry participants should monitor how quickly companies can set up domestic polysilicon and wafer production facilities to reduce their dependence on overseas suppliers.
The key monitorable for the coming months will be the progress of the proposed 30 GW polysilicon incentive scheme and whether domestic cell manufacturing capacity, currently at approximately 32 GW, can scale up fast enough to meet the rising demand from large-scale solar projects. Success in these areas will determine whether Indian solar manufacturers can sustain their growth and protect their profitability against global supply chain risks.
