Enphase Energy Secures Second Safe Harbor Agreement to Strengthen U.S. Residential Solar Growth

Enphase Energy announced the signing of a new safe harbor agreement with a major solar and battery financing company offering third-party ownership (TPO) solutions, including leases and power purchase agreements (PPAs). This marks Enphase’s second safe harbor agreement since the passage of the U.S. federal budget bill in July 2025.

Signed earlier this month, the agreement is expected to generate approximately $50 million in revenue for Enphase. It highlights the company’s growing role in the TPO segment, one of the most important growth channels for U.S. residential solar and energy storage. “Safe harbor agreements are a critical tool for keeping solar projects on track despite changing policy landscapes,” said Ken Fong, senior vice president and general manager of the Americas and APAC at Enphase Energy. “These agreements allow developers and financiers to move forward with confidence, safeguard project economics, and accelerate clean energy deployment. Enphase is committed to supporting every segment of the market, including TPO, as it expands access to affordable, reliable home energy systems.”

The agreement covers Enphase’s U.S.-manufactured IQ8HC™ Microinverters (with “DOM” SKUs), allowing projects to preserve eligibility for both the base Investment Tax Credit (ITC) and the domestic content bonus credit. By safe harboring equipment in advance, solar companies can lock in current tax credit benefits while mitigating risks from potential future policy changes.
