India is advancing rapidly in its renewable energy journey. Growth is now being driven not only by domestic demand but also by rising global exports and a growing share in international markets. Over the past few years, the country has taken decisive steps to position itself as one of the world’s largest solar manufacturing hubs, backed by significant investments in solar cell and module production capacity.
Let us understand the heavy tariff imposed by the US on Indian solar exports and assess whether this development could pose a challenge for the Indian solar industry and its investors, or create an opportunity for a strategic shift.
What’s Happening?
The US Department of Commerce has announced the imposition of a countervailing duty of around 126% on solar cells and modules imported from India. The decision follows an investigation into allegations that Indian solar manufacturers were benefiting from government subsidies that allegedly caused trade losses to US domestic producers.
In this case, the most stringent action has been taken against companies belonging to the Adani Group. Due to the failure to provide necessary financial information and alleged non-cooperation by Mundra Solar Energy and Mundra Solar PV during the US subsidy probe, the US administration applied ‘adverse facts available’ and imposed a punitive tariff of up to 125.87% on them. Exporters that were not individually investigated, such as Waaree Energies, will also face a similar high duty rate of 125.9%.
This action is not limited to India. It is part of a broader investigation involving countries in Southeast Asia. Initial countervailing duty rates have reportedly been set between 86% and 143% for Indonesia and around 81% for Laos.
Heavy Export Dependence on the US Market
The United States has historically been the largest market for India’s solar exports, which makes this tariff a significant setback for trade dynamics. The data highlights the scale of exposure.
According to reports, out of India’s total solar exports of $2,023.8 million, nearly 97%, approximately $1,972.7 million, were shipped to the US. In 2024 alone, exports worth $792.6 million were sent to America. Another estimate suggests that between April 2023 and November 2025, India exported solar products worth nearly Rs 34,000 crore, with the majority destined for the US. With such a steep duty in place, Indian products risk losing their price competitiveness in the US market. This could make it difficult for manufacturers to sustain volumes and effectively utilise their expanded production capacity.
Impact of Compliance and Government Incentives
The US Department of Commerce investigation primarily examined incentive schemes offered by the Indian government to support the domestic solar industry. These included Advance Authorisation, Duty Free Import Authorisation, Duty Drawback, RoDTEP, and the Export Promotion Capital Goods Scheme. US authorities believe that such incentives reduce production costs and amount to unfair subsidies in international trade.
The failure of Mundra Solar Energy and Mundra Solar PV to submit the required financial details during the investigation was treated as non-cooperation, leading to the application of higher punitive duty rates.
What Does This Mean for Investors?
A duty of around 126% on leading renewable energy exporters is likely to have a direct impact on export revenues and profit margins. Such a steep cost escalation can trigger volatility in stock prices in the near term, particularly for companies with significant exposure to the US market.
Market reaction reflects this concern. As of February 26, 2026, while the Nifty 50 rose 0.4% over the previous five trading sessions, Vikram Solar declined 18%. Saatvik Green Energy fell 8.6%, Waaree Energies slipped 5.9%, and Premier Energies dropped 4.4%. The trend indicates that companies with higher export dependence are experiencing sharper market corrections.
What’s Next?
India continues to expand its solar power footprint at a steady pace. According to data from the Central Electricity Authority, solar energy accounted for 10.3% of India’s total power capacity in January 2021. By January 2026, this share had risen to 27%.
The Ministry of New and Renewable Energy introduced the Production Linked Incentive (PLI) scheme for high-efficiency solar PV modules in April 2021. At that time, India’s manufacturing capacity stood at 8.2 GW. By the end of 2025, capacity had expanded to around 144 GW, enough to comfortably meet domestic demand.
However, despite this scale-up in manufacturing, the external trade environment remains uncertain. According to Ankit Jain, Vice President at ICRA Limited, the proposed duties and regulatory uncertainty in the US could lead to a significant decline in export volumes from India, which were around 3 GW last year.
If a substantial portion of this export volume is redirected to the domestic market due to restricted access to the US, pricing pressure could intensify. Increased supply in the local market may weigh on margins, potentially affecting the profitability of Indian solar module manufacturers in the near to medium term.
