Federal solar incentives remain available for public sector projects, but eligibility now depends on meeting specific construction and in-service deadlines. For K-12 schools and state and local governments using Direct Pay, timing has become the most critical factor in preserving project economics. Projects that miss these windows risk losing access to the federal Investment Tax Credit (ITC) entirely.
Given these constraints, public agencies should align board approvals, procurement timelines, and construction schedules now. Early action provides flexibility, while delays reduce options and can materially impact total project cost.
Critical Solar Incentive Dates
- July 4, 2026, deadline to begin physical construction to qualify for the ITC without a strict placed-in-service cutoff.
- December 31, 2027, placed-in-service deadline for projects that begin construction after July 4, 2026.
- Four-year continuity safe harbor, projects that begin construction on or before July 4, 2026, generally have up to four years to be placed in service, subject to IRS continuity requirements 1 2.
These dates should be treated as planning guardrails for any public sector solar or solar-plus-storage project moving forward. Veregy can help you evaluate timelines, manage risk, and map a practical path to decarbonization.
