Enphase Secures $52M Safe Harbor Deal with U.S. Solar Financier

Event summary

  • Enphase signed a $52M safe harbor agreement on April 28, 2026 with a U.S. solar financier for IQ9 Microinverters.
  • Total PWT backlog with TPO providers now stands at $873.7M, including $67.7M from Q4 2025 and $754M from earlier 2026.
  • Revenue from this backlog expected between 2027-2030, subject to project timing and demand.
  • Deal covers only IQ9 Microinverters, with additional revenue potential from cables, accessories, and IQ Batteries.

The big picture

This agreement reflects growing demand for safe harboring as solar developers seek to lock in tax credit eligibility amid evolving policy. The $873.7M backlog positions Enphase as a key supplier in the TPO market, though revenue recognition remains dependent on project execution over the next several years. The deal underscores the strategic importance of U.S.-manufactured equipment in qualifying for domestic content incentives.
