‘Buy American’ Shifts to ‘Don’t Buy Chinese’ for Government Solar Projects

Why It Matters

The shift intensifies supply‑chain scrutiny and creates immediate market opportunities for domestic and allied manufacturers while reshaping federal renewable‑energy spending.

Key Takeaways

• BABA Act mandates 55% domestic content for federal solar.
• Waivers granted when U.S.-made panels unavailable.
• NDAA FY2026 adds FEOC ban on Chinese equipment.
• Congress demands policy; Treasury guidance still pending.
• Non‑Chinese alternatives like SMA already in use.

Pulse Analysis

The recent policy realignment reflects growing geopolitical anxiety over supply‑chain security. While the Build America, Buy America Act continues to push for American‑made components, its 55% cost threshold proves difficult for solar panels, inverters and batteries, prompting frequent waivers. This tension underscores a broader strategic shift: rather than insisting on wholly domestic products, the government now emphasizes eliminating Chinese‑origin hardware, a move codified in the FY2026 National Defense Authorization Act’s FEOC provisions. The legislation targets the Department of War, mandating that any solar hardware sourced directly by the department avoid entities of concern, including China, Iran, North Korea and Russia.

Implementation, however, remains in flux. The Department of the Treasury has yet to issue detailed FEOC guidance, and the Department of War has not clarified compliance pathways, prompting a bipartisan letter from ten House Republicans urging immediate policy action. Meanwhile, the Department of Energy’s recent investigations found no conclusive evidence of malicious code in Chinese inverters, tempering some of the alarm but not easing congressional pressure. The uncertainty forces project engineers to balance security mandates with practical availability, often turning to proven non‑Chinese alternatives such as German‑made SMA inverters, which already meet performance and safety standards.

For the solar industry, the evolving rules generate both risk and opportunity. Domestic manufacturers like First Solar and emerging U.S. panel assemblers stand to benefit from heightened demand, yet they must scale quickly to meet the 55% cost share and avoid future waivers. International players not tied to China—European and Taiwanese firms—are positioned to capture federal contracts, accelerating diversification of the U.S. solar supply chain. As agencies await formal FEOC guidance, the market is likely to see a surge in procurement of non‑Chinese components, reshaping vendor relationships and potentially driving down costs through increased competition.
