Building India's Solar Supply Chain
ReNew Energy's decision to build its own solar ingot and wafer manufacturing facility marks a significant step toward integrating its operations. This investment tackles a key challenge in India's renewable energy sector, aiming to reduce reliance on imported components. It strengthens ReNew's position as India works toward its ambitious target of 500 GW of non-fossil fuel capacity by 2030.
New Facility Boosts In-House Production
The company has started construction on a 6.5 GW solar ingot and wafer manufacturing plant in Anakapalli district, Andhra Pradesh, with a ₹5,400 crore investment. The project includes a 100 MW captive power plant and is a crucial part of ReNew's plan for in-house production in its solar panel manufacturing. By producing ingots and wafers locally, ReNew aims to secure key components, avoid supply chain problems, and manage costs. This initiative is part of ReNew's larger commitment of ₹82,000 crore to Andhra Pradesh, initially pledged in November 2025. The plant is expected to be ready within 24 months and create over 2,100 jobs. As of April 2026, ReNew's market capitalization was about $1.97 billion, with a P/E ratio of around 12.36.
India's Solar Manufacturing Drive and Competitors
ReNew's investment aligns with India's national goal to build a strong domestic solar manufacturing industry, supported by the Production Linked Incentive (PLI) scheme. This scheme has already helped establish 2.2 GW of ingot-wafer capacity nationwide. ReNew's facility will significantly add to this. India's solar module manufacturing capacity is projected to exceed 165 GW by 2027, positioning the country as a major global producer.
Competitors like Adani Enterprises, Reliance Industries, Waaree Energies, and Premier Energies are also moving towards in-house production. Adani New Industries plans a 10 GW integrated facility by 2027, and Reliance Industries a 20 GW solar gigafactory. INA Solar is setting up a 4.5 GW solar cell plant, and Gautam Solar is expanding with a 5 GW cell facility. ReNew's move places it in direct competition for domestic market share and global export opportunities. While India's module and cell manufacturing has grown, the upstream segments for polysilicon and wafer production remain a challenge, with domestic capacity still not meeting demand. ReNew's investment directly addresses this gap.
The broader Indian renewable energy sector is growing rapidly, with over 32 GW of capacity expected in fiscal year 2026. Government policies, including increased subsidies for renewables and ambitious targets, show strong government support. However, delays in power purchase agreements (PPAs) and project execution remain.
Potential Challenges and Analyst Views
While ReNew's move to in-house production is strategic, it carries risks. Manufacturing ingots and wafers requires significant investment. The sector faces volatile global raw material prices and the risk of too much production if demand doesn't meet forecasts. India's upstream manufacturing still lags module and cell production, leading to potential supply chain pressures and increased reliance on imports for some inputs.
Analysts have mixed views on ReNew Energy Global, with a consensus rating leaning towards 'Hold' or 'Reduce'. Some analysts have issued 'Sell' and 'Hold' ratings, leading to a 'Reduce' consensus. Average price targets suggest potential upside, with one target at $6.52, representing a 25.53% increase from a recent price of $5.19. However, cautious ratings suggest investors are concerned about execution risks and future profits amid strong competition. The company's P/E ratio, around 12.36, is lower than the market average of 44.23, possibly indicating a lower valuation or market doubt about its growth path.
Broader Strategy and Future Growth
This new manufacturing facility is a key part of ReNew's broader ₹82,000 crore investment plan in Andhra Pradesh, which also includes projects for large hybrid renewable energy projects and battery energy storage systems. By building an integrated clean energy ecosystem, ReNew aims to improve its overall value and stability. The company is positioning itself to benefit from India's rapid energy transition, but success will depend on efficient project execution and navigating the competitive solar manufacturing market in India.
