In Short : An important step for developers looking for complete domestic content tax credits is the fact that a number of solar tracker manufacturers in the United States are now providing systems that satisfy 100% domestic content standards, which are approved by IRS safe harbor guidelines under the Inflation Reduction Act (IRA). OMCO Solar, Terrasmart, Nextracker, ARRAY Technologies, FTC Solar, and GameChange Solar are among the companies that are stepping forward to fill supply chain gaps and streamline credit eligibility.
Forecasts and Market Trends
With the support of a strong local production footprint in Arizona and elsewhere, OMCO Solar is now exporting solar trackers that are entirely made in the United States in collaboration with Kinematics.
Terrasmart is expanding its capacity to accommodate around 500 MW of new PV projects by bringing ground screw manufacture in-house at its Cincinnati location.
Nextracker has grown to more than 25 U.S. factories with a combined capacity of over 30 GW annually, and has announced its first tracker deliveries with entirely American content in late 2024.
ENGIE’s 200 MW Emerald Green Solar project in Indiana will get OmniTrack trackers from ARRAY Technologies that are 100% domestically compliant, guaranteeing complete tax credit eligibility.
Module-agnostic safe harbor solutions are being promoted by FTC Solar and GameChange Solar; in Q4 2025, FTC Solar’s entirely domestic trackers will be available for purchase.
Effect on Tax Law and Clean Energy
Thanks to IRS “safe harbor” tables that ease documentation requirements, these capabilities expedite the process for solar projects to obtain the Domestic Content Bonus Tax benefit, an additional 10% benefit under the IRA.
The focus on entirely domestic components boosts the resiliency of the American economy, lessens reliance on imports, and speeds up the expansion of domestic clean-energy production.
The Significance of It
Tracker manufacturers who meet the entire U.S. content requirements provide developers with financial benefits, transparency, and a decrease in risk under the new tax credit regulations that prioritize domestic supply chains.
The solar industry’s shift toward supply chain localization, which aligns industry structure with long-term sustainability and competitiveness, is highlighted by these advances.
The bottom line
Manufacturers of solar trackers in the United States have successfully matched their production capacities and supply plans with IRA tax credit schemes. They are supporting American leadership in clean energy by facilitating more efficient and economical project development through the provision of safe harbor provisions and the delivery of fully compliant, 100% domestic-content solutions.
