Indian solar exports to the United States have come under renewed scrutiny following a petition filed by major American solar manufacturers, potentially threatening the progress Indian firms have made in the global clean energy supply chain.
The petition, led by First Solar, Mission Solar Energy, Qcells, and Talon PV Solar Solutions, under the Alliance for American Solar Manufacturing and Trade (AASMT)—alleges that solar module imports from India, Indonesia, and Laos are being sold below fair market value and are backed by illegal subsidies. The filing has prompted an anti-dumping and countervailing duty (AD/CVD) investigation by the U.S. Department of Commerce and the International Trade Commission (ITC).
According to the complaint, the dumping margins are steep 213.96% for India, 89.65% for Indonesia, and up to 249.09% for Laos. If duties are imposed following preliminary and final rulings, Indian solar exports could face major disruption.
The development poses a major setback for Indian manufacturers, who had recently gained traction in the U.S. following earlier duties on module imports from Cambodia, Malaysia, Thailand, and Vietnam. Indian firms like Waaree, Adani Enterprises, and Vikram Solar capitalized on this shift, jointly exporting 4.4 GW of modules to the U.S. in 2024, accounting for nearly 8% of total U.S. imports.
The potential duties may halt this momentum. Waaree, with approximately 57% of its order book linked to the U.S., stands to be particularly affected. Meanwhile, companies like Premier Energies, which focus on the domestic market, may experience less impact. Brokerage firm Kotak Institutional Equities warns that the investigation could derail shipment schedules, reduce pricing competitiveness, and necessitate strategic realignments.
The timing of the investigation adds further complexity for American developers hoping to benefit from incentives under the U.S. government’s renewable energy program, known as the ‘Big Beautiful Bill,’ which rewards projects completed before 2027 or initiated by July 4, 2026.
Despite these external pressures, India’s solar manufacturing sector is undergoing a period of remarkable growth. Domestic module manufacturing capacity now stands at 74 GW, with solar cell capacity at 25 GW. By 2030, India is projected to reach 125 GW in modules and 40 GW in cells, figures unimaginable just a few years ago.
Ashish Agarwal, Head of Solar & Storage at BluPine Energy, acknowledged the short-term challenges but stressed the long-term resilience. “Yes, this probe can create temporary headwinds, but we cannot ignore the robust tailwinds from domestic policy support in India,” he said.
Government initiatives such as the Production Linked Incentive (PLI) scheme and import duties on Chinese modules have supported local manufacturing, positioning India as a credible player in the global solar landscape. Still, India’s contribution to the solar cell market remains limited, hindered by higher domestic prices, limited manufacturing capacity, and strong competition from Malaysian and South Korean producers.
The U.S., for example, has 51 GW of module capacity but only 2 GW in cells. Although the U.S. is expected to reach 9 GW of cell capacity by the end of 2025, a substantial gap will persist, creating a potential opportunity for countries like India, provided they can scale up efficiently.
Prashant Mathur, CEO of Saatvik Green Energy, believes the investigation represents a turning point. “The petitions signal a structural shift in global supply chains. While they bring complexity, they also underscore the importance of having credible, rule-abiding partners. India’s reputation as a transparent and democratic supplier could actually work to its advantage in the long run,” he noted.
The challenge, however, is immediate. With steady monthly Indian exports to the U.S. of around 300 MW, any trade barriers could create a sudden supply void. Indonesia and Laos, also named in the petition, face similar risks after benefiting from earlier U.S. measures against Southeast Asian suppliers.
While European and Middle Eastern markets may offer alternative demand, the U.S. remains a crucial destination for Indian solar products due to its scale and pricing benefits. A shift in U.S. trade policy could dampen growth projections and weaken investor confidence in India’s fast-growing renewable manufacturing sector.
As the investigation proceeds, Indian exporters will need to swiftly diversify markets and bolster domestic sales under government-backed schemes. Importantly, scaling solar cell production, long a missing link in India’s supply chain, will be key to building a comprehensive, globally competitive solar industry.
