Federal credit status (2026): the 30% residential clean-energy credit (Section 25D) was repealed for systems purchased and placed in service after Dec 31, 2025 — cash and financed buyers can no longer claim it. A leased or PPA system can still access the commercial credit (Section 48E), which its owner can claim through 2027 and may pass on as a lower price. That makes Delaware's state and utility incentives, not the federal credit, the main lever on your 2026 payback.
