The federal residential solar tax credit was killed a decade early, forcing homeowners into leases as the only way to get a subsidy

On July 4, 2025, the One Big Beautiful Bill Act terminated Section 25D -- the 30% federal tax credit for homeowner-purchased solar systems -- nearly a decade ahead of its original 2034 expiration. For a typical $30,000 installation, this eliminated $9,000 in direct tax savings overnight. However, the commercial tax credit (Section 48E) was preserved for third-party-owned systems through 2027, meaning solar leases and PPAs can still capture the credit -- but homeowner-purchased systems cannot. This matters because the tax credit asymmetry creates a perverse incentive structure. Homeowners who want to own their solar system outright -- which gives them the most long-term financial benefit, equity in their home, and control over their energy -- now pay full price. But if they lease or sign a PPA, the solar company captures the 30% credit and passes some (but not all) of the savings through in lower monthly payments, while retaining ownership of the equipment on the homeowner's roof for 20-25 years. This shifts the entire residential market toward the third-party ownership model that has historically generated the most consumer complaints: aggressive sales tactics, misleading savings projections, inflexible lease terms, and the house-selling complications described above. The homeowner who would be best served by buying outright is now financially penalized for doing so. This problem persists because the tax credit termination was a political decision embedded in a massive budget reconciliation bill, not a deliberate energy policy choice. The residential credit was an easy target for deficit reduction because the solar industry's lobbying power is concentrated in commercial and utility-scale developers, not in residential installers. The result is a structurally tilted market: commercial solar interests preserved their credit while individual homeowners lost theirs. SEIA projects a 19% decline in residential installations in 2026, and the shift to leases means more homeowners will be locked into long-term contracts with companies that may not survive the next industry downturn.
