Domestic Content
Sollega's FastRack FR510 is engineered and manufactured in the United States. For developers chasing the federal Domestic Content Bonus or meeting Buy American and domestic-sourcing requirements, our racking is the simplest way to add verified U.S. content to your project.
The opportunity
Why domestic content matters
Federal incentives reward solar projects built with American-made steel, iron, and manufactured products. Meeting the Domestic Cost Percentage can unlock a meaningful bonus on top of the Investment or Production Tax Credit, and many public-sector owners now require domestic sourcing outright. Because racking is a sizable, fully manufactured part of any array, choosing a U.S.-made mounting system is one of the most direct ways to move your project toward the threshold.

Questions
Frequently asked questions
What is the Domestic Content Bonus?
It is a federal tax-credit adder for clean-energy projects that use a qualifying percentage of U.S.-made steel, iron, and manufactured products. Solar projects must meet an escalating Domestic Cost Percentage — roughly 45% for projects beginning construction in 2025, 50% in 2026, and 55% thereafter — alongside a 100% requirement for structural steel and iron. Eligibility and current thresholds change frequently; always confirm with your tax advisor.
Does Sollega racking qualify as domestic content?
The FastRack FR510-6dg is manufactured 100% in the U.S.A. As a manufactured product, its domestic cost can be included in your project's Domestic Cost Percentage calculation. Sollega cannot certify your overall project — that depends on every component — but our racking strengthens the domestic side of the ledger.
What documentation do you provide?
A Made in USA Certificate of Compliance and a FEOC Compliance Certification are available for download above, and we can supply project-specific cost and sourcing letters on request.
Is the FR510 recyclable?
Yes. The FR510 is molded from glass-reinforced nylon 6/6 and is recyclable at the end of its useful life — domestic sourcing with a lower lifecycle footprint.
