The One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025, has sent ripples through the renewable energy sector, particularly affecting solar and battery storage industries. This legislation reshapes tax incentives, imposes strict supply chain rules, and alters the trajectory of clean energy adoption in the U.S. For homeowners, developers, and businesses invested in solar and armazenamento de bateria, understanding these changes is crucial. The key impacts of the OBBBA and what they mean for the future of renewable energy.
1. Accelerated Phase-Out of Solar Tax Credits
The OBBBA dramatically shortens the timeline for solar tax credits, catching many in the industry off guard.
Residential Solar: The 30% federal tax credit for residential solar installations, previously set to extend through 2034 under the Inflation Reduction Act, now expires on December 31, 2025. This applies to solar panels, geothermal heat pumps, and battery installations. For homeowners, this could double the payback period for solar systems—from 10 to 20 years in some cases—making solar less financially appealing in the short term.
Utility-Scale Solar: For larger projects, tax credits under Sections 45Y (Clean Electricity Production Credit) and 48E (Clean Electricity Investment Credit) are repealed for projects not in service by December 31, 2027, unless construction begins by July 4, 2026. This tight deadline is pushing developers to fast-track projects, adding pressure to already complex timelines.
What This Means: Homeowners considering solar should act quickly to secure the 30% credit before it vanishes. For developers, the race is on to break ground before mid-2026, or risk losing critical financial incentives.
2. Battery Storage Gets a Boost
While solar faces headwinds, armazenamento de bateria emerges as a bright spot under the OBBBA.
Unlike solar, battery storage projects retain full tax credit eligibility under Section 48E through 2033, with a gradual phase-down thereafter (75% in 2034, 50% in 2035, and 0% in 2036). This applies to both standalone storage systems and those paired with solar or wind.
This favorable treatment is encouraging solar installers to pivot toward battery storage, potentially through creative financing models like leasing batteries separately from solar systems.
What This Means: Battery storage is poised for growth, offering a lifeline for renewable energy integration. Homeowners and businesses can still capitalize on tax credits for storage, making it a smart add-on to existing or new solar setups.
3. Stricter Foreign Entity of Concern (FEOC) Rules
The OBBBA introduces tough restrictions on components sourced from “foreign entities of concern” (FEOC), such as China, Iran, Russia, and North Korea.
Starting January 1, 2026, solar and battery storage projects using FEOC components lose tax credit eligibility unless they meet stringent domestic content thresholds. For solar, 40% of manufactured product value must come from non-FEOC sources in 2026, rising to 60% by 2030. For storage, the threshold starts at 55% in 2026 and climbs to 75% after 2029.
These rules pose challenges, as much of the global supply chain for solar panels and batteries relies on Chinese manufacturing, potentially driving up costs and delaying projects.
What This Means: Companies will need to reconfigure supply chains to prioritize U.S. or allied manufacturing, which could increase costs but also spur domestic production. Consumers may see higher prices for solar and storage systems in the near term.
4. Tougher Domestic Content Requirements
The OBBBA tightens domestic content rules for tax credit bonuses, further emphasizing U.S. manufacturing.
Solar projects starting construction after June 16, 2025, must meet a 45% domestic content threshold (up from 40%), increasing to 55% after 2026. Battery storage faces even higher thresholds, starting at 55% in 2026 and reaching 75% post-2029.
These requirements aim to bolster American manufacturing but could strain project timelines and budgets due to limited domestic supply capacity.
What This Means: While this creates opportunities for U.S. manufacturers, it may slow down project development as companies scramble to source compliant components.
5. Changes to Manufacturing Credits
The OBBBA modifies the Section 45X Advanced Manufacturing Production Tax Credit, which supports U.S. production of solar and battery components.
Credits for critical minerals used in batteries and solar components face reductions starting in 2031 (75% in 2031, 50% in 2032, 25% in 2033, 0% thereafter). However, credits for battery modules and components like voltage-sense harnesses remain intact, encouraging domestic integration.
FEOC restrictions also apply here, limiting credits for products using components from prohibited foreign entities.
What This Means: Manufacturers have a window to capitalize on these credits, but they’ll need to shift away from FEOC suppliers to maintain eligibility, potentially reshaping the global supply chain.
6. Broader Economic and Industry Impacts
The OBBBA’s changes have far-reaching consequences for the renewable energy sector.
The Solar Energy Industries Association (SEIA) warns of significant fallout: up to 330,000 job losses, 331 factory closures, and $300 billion in lost investments due to reduced solar incentives. States like Illinois, New Mexico, and Wyoming could see electricity bills rise by up to 30% by 2029.
The Rhodium Group projects a 57–72% reduction in clean energy capacity additions by 2035, with solar and storage hit hard. This could lead to energy shortages, especially as demand grows from sectors like AI data centers.
What This Means: The renewable energy industry faces a challenging road ahead, with potential job losses and higher energy costs affecting consumers and businesses alike.
7. Executive Order Adds Uncertainty
On July 7, 2025, President Trump issued an executive order directing the U.S. Treasury to revise “beginning-of-construction” safe harbors within 45 days. This requires a “substantial portion” of a facility to be built, adding ambiguity and complexity for solar developers aiming to meet the July 4, 2026, construction deadline.
What This Means: Developers face increased uncertainty, as unclear definitions could jeopardize tax credit eligibility for projects not sufficiently advanced by the deadline.
What’s Next for Solar and Battery Storage?
The OBBBA creates a mixed landscape for solar and battery storage. While solar faces a tough road with expiring tax credits and stringent supply chain rules, battery storage benefits from extended incentives, offering a path for growth. Homeowners should act fast to install solar before the 2025 credit deadline, while developers and manufacturers must adapt to domestic content requirements and navigate supply chain challenges.
For the renewable energy industry, the focus is shifting toward resilience—leveraging battery storage, investing in U.S. manufacturing, and planning projects strategically to meet tight deadlines. As the energy transition evolves, staying informed and agile will be key to thriving in this new regulatory environment.
