The 30% federal residential solar tax credit (Section 25D) expired December 31, 2025, ended early by the One Big Beautiful Bill Act. Homeowners who buy a system with cash or a loan in 2026 receive $0 in federal credit — a major shift from the prior decade of solar marketing. The commercial credit (Section 48/48E) is still active for business-owned systems and for lease/PPA providers, which is why some leased or PPA offers can still reflect a lower effective rate even without a direct homeowner credit. State tax credits, utility rebates, property tax exemptions and SRECs remain available in many areas and are where the real 2026 savings now come from — check a database like DSIRE for your specific state.
