The solar industry is at a crossroads, with recent policy shifts and production dynamics creating both challenges and opportunities. The Trump administration’s Section 232 tariffs on polysilicon imports are set to reshape the domestic solar supply chain, while India’s rapid expansion in solar module production is causing concerns about overcapacity. These developments are influencing investment strategies and market dynamics for key players like First Solar and Corning.
In the United States, the tariffs introduced in August 2026 have sparked discussions about potential government equity stakes in the solar sector, reminiscent of the Intel-style deals seen in the semiconductor industry. Meanwhile, India’s solar manufacturing capacity has grown significantly, but the industry is grappling with underutilization and the need to diversify export markets.
United States: Tariffs and Government Equity Stakes
The Trump administration’s tariffs on polysilicon imports, justified by national security concerns, have introduced a 15% tariff and a minimum import price floor. This move is seen as a strategic shift towards direct government equity investments in the solar supply chain, building on the industrial policy work initiated by the Biden administration.
Matt Roling a climate finance expert, suggests that companies in Section 232 sectors now carry ‘real, unpriced government-partnership optionality.’ However, this also introduces political risks that were not previously factored into valuations. The administration’s approach, characterized by a preference for equity over traditional grants and loans, is likely to influence the investment landscape for solar companies.
Key Players: First Solar and Corning
First Solar stands out due to its thin-film technology which bypasses the need for polysilicon. This gives the company structural immunity to the new tariffs, providing a durable advantage independent of future policy shifts. In contrast, Corning through its subsidiary Hemlock Semiconductor is a direct beneficiary of the tariffs and holds a $325 million CHIPS award, making it a prime candidate for potential equity conversions.
However, Corning’s upside is highly policy-contingent and complicated by its joint venture with Japan’s Shin-Etsu Handotai. Roling warns that any equity swap could be ‘messier than Intel’s swap,’ highlighting the complexities involved in such transactions.
Market Reactions and Performance
The initial market optimism for downstream installers like Sunrun and SunPower is expected to be short-lived, as higher polysilicon costs will act as a tax on their core business models. The financial impact of the tariffs is expected to become tangible in the first half of 2027, despite existing inventory and locked-in contracts providing a brief buffer.
As of the latest data, First Solar shares have experienced a 20.83% year-to-date drop with a 3.70% advance over the last year and a 1.57% fall over the last six months. In contrast, Corning shares have seen a 68.07% year-to-date rise with a 120.37% advance over the last year and an 8.27% fall over the last six months.
India: Overcapacity and Export Challenges
India’s solar manufacturing capacity has reached approximately 233 GW by June 2026, but manufacturers are operating at just 35–40% capacity utilization. This underutilization is particularly acute at the module level, where capacity additions have significantly outpaced demand. The risk of stranded assets is a growing concern, especially for standalone module manufacturers.
The imbalance in the supply chain, with module capacity far exceeding cell, wafer, and polysilicon capacity, highlights the need for upstream integration. The current Production Linked Incentive (PLI) framework primarily incentivizes manufacturers based on their level of integration, but capacity additions across components have remained uneven.
Export Opportunities and Challenges
Exports could become critical to absorbing India’s expanding production capacity. The timing is favorable, as leading Chinese producers are absorbing losses amid persistent oversupply, while Indian manufacturers have remained profitable. This provides an opportunity to channel capital towards upstream integration, manufacturing efficiency, and research and development (R&D).
However, India’s heavy reliance on the US market which currently absorbs the bulk of its solar shipments, has increased exposure to trade-policy risks. The European Union offers the most structured medium-term opportunity, as its policy frameworks increasingly favor supply-chain resilience and diversified sourcing. Indian manufacturers will need to remain competitive on cost and technology to secure market access.
Competing with China
The narrowing gap between Indian and Chinese solar module production is creating an opportunity for Indian manufacturers. However, converting this opportunity into higher export volumes will depend on how effectively they can compete with China, the world’s dominant solar supplier. Cost and technology remain the two major competitive gaps, but financial conditions are currently creating more avenues for Indian manufacturers.
Further additions in cell and wafer manufacturing are expected to reduce import dependence and improve cost competitiveness over time. Together with greater upstream integration, these investments could help Indian manufacturers strengthen their position in overseas markets and make exports a more important outlet for the country’s rapidly expanding solar manufacturing capacity.
