US Solar Policy Shift: What India's Renewable Energy Sector Must Watch in 2025

The United States solar policy landscape shifted materially in 2025 following the introduction of the One Big Beautiful Bill Act (OBBBA) and the imposition of Section 232 national-security tariffs on steel and aluminium imports. Hasan Nazar, head of policy at US clean energy finance firm Crux, told pv magazine's PV Talk podcast that the combined effect of these two policy moves represents 'a lot of good news' for the American solar industry — even as critics flag complexity and transition risk. For India, however, the calculus is more nuanced. India currently exports solar module components, cells, and finished panels to a range of markets, and any structural realignment of the world's largest economy's energy procurement rules sends immediate ripples through global photovoltaic supply chains. With India targeting 500 GW of renewable energy capacity by 2030 under its national clean energy roadmap — and developers such as Adani Green Energy, ReNew Power, Greenko, and NTPC Renewable Energy aggressively building pipelines — understanding how US policy changes reshape capital flows, module pricing, and technology partnerships is no longer optional. It is a strategic imperative.

What Is the OBBBA and How Does It Affect Solar?

The One Big Beautiful Bill Act, introduced in the US Congress in 2025, is a sweeping fiscal and energy package that preserves and in some respects extends key clean energy tax credits initially established under the Inflation Reduction Act (IRA). For the solar sector specifically, the OBBBA maintains the Investment Tax Credit (ITC) and Production Tax Credit (PTC) architecture that has underpinned a surge in US solar installations — the country added over 40 GW of utility-scale solar capacity in 2024 alone. Crux's Hasan Nazar highlighted that the bill's treatment of transferability and direct pay provisions for tax credits gives developers and financiers greater flexibility, reducing the frictional cost of deploying clean energy capital. This matters because a well-capitalised US solar market tends to compete aggressively for tier-one module supply globally, including from manufacturers with operations in India, Southeast Asia, and China. When US demand strengthens, global module prices typically tighten, affecting procurement costs for Indian developers sourcing panels for large projects in Rajasthan, Gujarat, and Tamil Nadu.

Section 232 tariffs — applied on national security grounds to steel and aluminium — add a second layer of complexity. Solar racking systems, mounting structures, and tracker components are steel-intensive, meaning these tariffs raise the balance-of-systems cost for US solar projects. Paradoxically, this could benefit Indian steel and component manufacturers if US buyers seek tariff-exempt supply chain alternatives, opening a potential export window for Indian firms supplying solar mounting hardware and galvanised structural steel to American EPC contractors.

How US Tariff Policy Reshapes Global Solar Supply Chains

The interaction between the OBBBA's demand stimulus and Section 232's cost pressures creates a bifurcated global supply chain environment. On one side, US domestic solar manufacturing — incentivised by IRA-era Advanced Manufacturing Production Credits (AMPC) and now reinforced by the OBBBA — is scaling rapidly, with companies like First Solar, Qcells, and a growing roster of new entrants expanding wafer, cell, and module capacity on American soil. On the other side, non-US manufacturers face a more complex access calculus: tariffs on modules of Chinese origin remain punishingly high, Southeast Asian manufacturers face their own anti-circumvention investigations, and this creates a structural gap that Indian manufacturers could conceivably fill. India's Production Linked Incentive (PLI) scheme for solar PV manufacturing — with an approved outlay of ₹24,000 crore targeting 10 GW of integrated cell and module capacity — positions companies like Waaree Energies, Vikram Solar, and Goldi Solar to supply both domestic and international markets. If US buyers find themselves seeking IRA-compliant, non-Chinese module supply, Indian manufacturers with PLI-backed scale are a credible alternative.

SECI tenders and MNRE's domestic content requirements already push Indian developers toward locally manufactured modules, but the global export opportunity is equally significant. Indian solar manufacturers exported modules worth approximately $2.5 billion in FY2024, with the US emerging as a key destination. A stable and incentive-rich US policy environment — which the OBBBA appears to offer — sustains that export demand and gives Indian PLI beneficiaries the volume throughput needed to achieve cost competitiveness.

What This Means for India's Energy Transition

India's 500 GW renewable energy target by 2030 is not achievable without a healthy, globally integrated solar manufacturing ecosystem. The PM Surya Ghar Muft Bijli Yojana scheme — targeting one crore rooftop solar installations — and SECI's ongoing utility-scale tender pipeline together represent the world's largest near-term solar procurement programme outside China. If US policy stability drives global module prices moderately higher by absorbing more tier-one supply, Indian developers will feel margin pressure on SECI-auctioned projects with fixed tariffs. Conversely, if Indian manufacturers capitalise on export opportunities opened by the US policy environment, PLI scheme targets become more commercially viable, strengthening the domestic manufacturing base that MNRE has long sought to build. The net effect on India's energy transition is likely positive — but only if Indian policymakers and developers actively engage with the supply chain shifts rather than treating US legislative developments as geographically remote.

Watch for three signals in the months ahead: first, whether MNRE adjusts domestic content requirement thresholds in response to global price movements; second, whether Indian module exporters like Waaree Energies formally announce US capacity reservation agreements tied to OBBBA-era demand; and third, how SECI structures its next tranche of large-scale tenders — particularly in Rajasthan's RE zones — to account for evolving module procurement costs. The global solar policy map is being redrawn, and India's position on it has rarely mattered more.
