Enphase Secures $52M Safe Harbor Deal, PWT Backlog Hits $873.7M
Enphase Energy signed a safe harbor agreement on April 28, 2026 with a U.S. TPO provider for IQ9 Microinverters, expecting about $52 million in revenue. This deal boosts its PWT order backlog to approximately $873.7 million, with revenues slated for recognition between 2027 and 2030.
1. New Safe Harbor Agreement
Enphase Energy entered into a safe harbor agreement on April 28, 2026 with a U.S. solar and battery financing company that offers third-party ownership leases and PPAs. The deal covers IQ9 Microinverters for residential and commercial projects, expected to generate approximately $52 million in revenue.
2. PWT Order Backlog Growth
The new agreement raises Enphase’s physical work test (PWT) order backlog with TPO providers to about $873.7 million. This total includes $67.7 million booked in Q4 2025, $754 million signed earlier in 2026, and the recent $52 million addition.
3. Revenue Recognition Timeline and Additional Opportunities
Enphase expects to recognize revenue from the PWT backlog between 2027 and 2030, subject to project timing and demand. Cables, accessories and IQ Batteries represent potential additional revenue streams attached to the microinverter systems over the same period.
4. Tax Credit and Strategic Significance
By safe harboring equipment now, project developers can preserve eligibility for the base investment tax credit and the domestic content bonus credit. This approach reduces uncertainty around future project economics and supports long-term solar deployment planning.
