At this year’s Intersolar 2025 in San Diego, Energy Solutions and Supplies (ESAS) had the opportunity to attend two standout sessions that shed light on how the Inflation Reduction Act (IRA), domestic manufacturing incentives, and trade policy are reshaping the solar and storage landscape. Below is our key take on the conversations and how these developments intersect with ESAS’s capabilities as a nationwide solar and energy storage distributor.
1. Why Domestic Manufacturing Matters More Than Ever
One of the major themes from the panels was the United States’ growing determination to secure its solar supply chain. Speakers underscored the vulnerabilities of relying heavily on imported modules, cells, and components—especially in light of geopolitical risks and China’s dominance in polysilicon, wafers, cells, and modules. Although past trade remedies (like tariffs) helped spur some manufacturing activity, the speakers agreed that a robust domestic industrial policy—aligned with trade policy—is the missing ingredient to support real, scalable U.S. manufacturing.
Key Points:
- Innovation Happens on the Factory Floor: Panelists emphasized that breakthroughs in efficiency and cost reductions often occur during mass production. If America wants to lead on next-generation technologies (e.g., tandem cells, perovskites), it needs factories and R&D happening here at home.
- Scaling Up the Entire Supply Chain: From polysilicon to inverters, reestablishing a U.S.-based manufacturing ecosystem requires more than just final assembly. Tools, glass, and other subcomponents must be domestically produced as well to truly claim “Made in the USA.”
2. The IRA: A Game-Changer or Work in Progress?
The Inflation Reduction Act (IRA) and related policies like 45X production tax credits and the Domestic Content Bonus ITC/PTC surfaced as major catalysts. According to panelists, these incentives are already driving tens of billions of dollars in announced U.S. manufacturing investments. However, several challenges remain:
Key Points:
- Three-Legged Stool—Tariffs, Tax Credits, and Domestic Content: To counter China’s large-scale subsidization, the U.S. policy framework uses a combination of protective tariffs, robust tax credits, and a bonus for using domestic content in solar projects. Each leg of this policy “stool” needs to remain intact for stable, long-term industry growth.
- Guidance Gaps & Future Adjustments: Both sessions stressed that some parts of the IRA need refinement—particularly on how to calculate domestic content and on the correct credit levels for upstream components such as wafers, ingots, and polysilicon. Legislative and regulatory tweaks over the next couple of years will likely influence project viability.
3. Balancing Policy Ambitions with Market Realities
While the sentiment at Intersolar 2025 was overwhelmingly pro-domestic-manufacturing, panelists also acknowledged practical constraints:
- Complex Global Supply Chains: Even if a module assembly plant is built in the U.S., key equipment and materials may still come from overseas. Policymakers need to account for the time and capital it takes to build every link in the supply chain—from crucibles for ingots to specialized glass.
- Phased-In Approaches: A sudden, strict requirement on fully U.S.-made polysilicon, wafers, and cells could stall projects. Any new policy rules will likely feature transition periods to avoid short-term disruptions.
How ESAS Supports Domestic Content Strategies
As a national wholesale distributor of solar and energy storage solutions, ESAS is uniquely positioned to help project developers, ESCOs, and EPCs navigate these policy changes:
- ESAS Logistics – We provide nationwide warehousing and seamless distribution, ensuring supply chain reliability even when local content rules tighten.
- ESAS Professional Services – Our technical and engineering expertise can help you design projects that meet domestic content thresholds and tap into IRA incentives.
- ESAS Marketplace – We work directly with OEMs, including U.S.-based panel and racking manufacturers, giving our clients direct access to top-tier solar products that qualify for these evolving incentive programs.
- ESAS 3R (Reclaim, Recycle, Reuse) – Our end-of-life solutions enable you to maintain compliance with sustainability goals and domestic recycling initiatives, closing the loop on older or decommissioned equipment.
Looking Ahead
From the sessions, it’s clear that domestic manufacturing and robust federal incentives are no passing trend. Policymakers are doubling down, spurred by national security, job creation, and climate imperatives. For solar developers and contractors, this moment presents a unique opportunity: align your procurement strategy with IRA-driven incentives to gain a competitive edge and long-term cost stability.
