BABA Compliance — Buy American Act for Solar Projects
Navigating federal procurement requirements for solar projects. The Build America, Buy America Act (BABA) requires that all iron, steel, manufactured products, and construction materials used in federally funded infrastructure projects be produced in the United States.
For solar contractors and EPCs working on federal, state, or utility-funded projects, BABA compliance is not optional — it's mandatory. PES Supply provides verified BABA-compliant products with complete documentation, ensuring your project qualifies for federal funding and the 10% domestic content bonus credit under the Inflation Reduction Act (IRA).
What is BABA Compliance?
The Build America, Buy America Act (BABA), enacted as part of the Infrastructure Investment and Jobs Act (IIJA) of 2021, establishes domestic content requirements for federally funded infrastructure projects. For solar projects, this means that solar panels, inverters, racking systems, steel, and other manufactured components must meet specific domestic content thresholds.
The most significant benefit for project owners is the 10% domestic content bonus credit available under the Inflation Reduction Act (IRA) for projects that use domestic content meeting BABA requirements. Under the IRA, projects meeting BABA domestic content requirements can qualify for a 10% additional tax credit on top of the standard 30% Investment Tax Credit (ITC) or Production Tax Credit (PTC). This means a 30% ITC becomes a 40% ITC — a massive difference on million-dollar projects.
Updated BABA Requirements (2025-2026)
The Office of Management and Budget (OMB) has issued implementing guidance under M-22-11 and subsequent updates that define the specific requirements:
| Requirement | Details |
|---|---|
| Iron & Steel | All iron and steel used in the project must be produced in the United States — from melting and pouring through manufacturing. |
| Manufactured Products | Manufactured products must be produced in the United States, meaning the final assembly of the product occurs in the U.S. and the cost of U.S.-sourced components exceeds 55% of total component costs. |
| Construction Materials | All construction materials (including non-iron/steel items like lumber, drywall, glass) must be produced in the United States. |
| De Minimis Waiver | Small quantities of non-compliant materials may be permitted if they constitute less than 5% of total material cost (capped at $2,500). |
| Public Interest Waiver | Available when domestic content requirements are not in the public interest or compliant products are not available in sufficient quantities. |
| IRA Bonus Credit | Projects meeting domestic content requirements receive an additional 10% ITC/PTC bonus (40% total ITC vs. 30% standard). |
