Solar tracker manufacturer Soltec has confirmed that its domestically produced SFOne and SF7 series single-axis trackers now carry certification demonstrating compliance with U.S. Treasury guidance on prohibited foreign entities, a designation increasingly critical for utility-scale solar developers navigating domestic content requirements.

PFE Certification and What It Covers

The certification applies to both the SFOne and SF7 tracker lines, available in one-in-portrait and two-in-portrait configurations. Compliance with prohibited foreign entity, or PFE, rules has become a central concern for project developers seeking to qualify for federal incentives tied to domestic content standards. Soltec's announcement positions the company to provide formal documentation of that compliance directly to project owners, removing a potential administrative hurdle in the qualification process.

The certification aligns with Treasury Department guidance governing which entities and supply chains are considered permissible under current law — guidance that has grown more consequential as incentive structures under recent federal energy legislation have taken shape.

Domestic Content Timeline

According to one source, Soltec has been capable of offering tracker solutions with 100% U.S. domestic content since the end of last year. The newly announced PFE-compliant certification represents a formalization of that capability, giving project developers the documented proof of compliance that lenders, tax equity partners, and federal programs typically require.

The SFOne and SF7 product families cover a range of utility-scale deployment scenarios, and the availability of both 1P and 2P variants under this certification gives developers flexibility depending on site conditions and project design.

Broader Market Context

The announcement comes as the U.S. solar industry faces heightened scrutiny over supply chain origins, particularly regarding components tied to foreign entities of concern, commonly referred to as FEOCs. Federal policy has increasingly tied incentive eligibility to verifiable domestic content and supply chain transparency, prompting manufacturers and suppliers across the solar value chain to pursue formal certifications.

For tracker suppliers specifically, the ability to provide certification — rather than simply claiming compliance — has become a competitive differentiator as project developers work to satisfy due diligence requirements from investors and federal program administrators. Soltec's move reflects a broader industry pattern of companies formalizing and documenting supply chain compliance as regulatory and market conditions continue to evolve in the U.S. utility-scale sector.
