GRIDFLEX^®

GRIDFLEX^® is designed to meet domestic content safe harbor guidance requirements.

Unirac’s GRIDFLEX® racking systems are domestically produced and have all the key features that customers value. GRIDFLEX® 5D and GRIDFLEX® 10D may provide taxpayers with an option to claim the 10% Domestic Content Bonus Credit (DCBC)*!

Under the IRS’s First Updated Safe Harbor Guidance (Notice 2025-08), the GRIDFLEX® racking systems may contribute up to 19.6% of the total 50% domestic content requirement for a complete PV installation for MLPE based systems. When paired with select domestic content inverters on the market, the GRIDFLEX® 5D and GRIDFLEX® 10D racking systems can play a pivotal role in meeting the 50% domestic content threshold. Unirac has documentation for your tax professionals to help them determine if GRIDFLEX® racking systems work with your or your financer’s tax strategy.
