Solar Leases and PPAs Emerge as the Only Path to Federal Tax Savings for Homeowners
With the residential federal solar Investment Tax Credit (Section 25D) ended on January 1, 2026, third-party owned solar arrangements have emerged as the only remaining route for homeowners to access a 30% federal tax credit. Solar leases and power purchase agreements still qualify under the commercial Section 48E ITC, which remains in effect for systems where a third party owns the equipment and construction begins by July 4, 2026. TPO providers fold the credit into customer pricing, which translates into lower monthly lease and PPA rates than would otherwise be possible. Industry analysts at SEIA project TPO market share to grow from roughly 35% of residential installations to as much as 60% by year end as more homeowners look at zero-down options.
