Most homeowners shopping for solar right now are operating on outdated information. They assume some version of the 30% federal tax credit is still out there, maybe reduced, maybe with an income cap, but still available if they jump through the right hoops. I’ll be honest: I spent the better part of three weeks talking to installers, reading the fine print of Public Law 119-21, and going through the Q2 2026 market data before I fully understood how abrupt and complete the break actually was. The federal residential solar tax credit did not phase down. It did not sunset gracefully. On January 1, 2026, it went from 30% to zero. Full stop.
The One Big Beautiful Bill Act, signed on July 4, 2025, repealed Section 25D roughly seven years ahead of the schedule the Inflation Reduction Act had set. No transition year. No grandfathering for systems under contract. If your panels weren’t “placed in service” by December 31, 2025, you get nothing from the federal government on a direct purchase. On a $25,000 system, that’s $7,500 gone. That’s real money, and it’s changing how a lot of people think about the lease vs. buy decision in ways that would have seemed bizarre just 18 months ago.
What surprised me was how little chaos this created in installation numbers, at least on the surface. The residential segment installed 1,179 MWdc in Q1 2026, a 6% year-over-year increase, according to SEIA’s Q2 2026 Solar Market Insight Report. But dig into that number and it’s partly an echo of the 2025 rush. Installers were finishing systems contracted before the deadline. The real demand picture for Q3 and Q4 2026 will be telling.
- The 30% federal residential solar tax credit (Section 25D) expired December 31, 2025, with no phase-down.
- Cash and loan buyers get $0 in federal credits in 2026; there is no workaround for direct purchases.
- Leases and PPAs still benefit indirectly from the 30% Section 48E commercial credit through end of 2027.
- Nearly 50% of new residential solar installs in Q1 2026 were paired with batteries, a record attach rate.
- State incentives, utility rebates, and net metering rules now matter far more than they did a year ago.
The Lease/PPA Loophole Is Real (With Caveats)
Here’s the part that genuinely surprised me when I went looking. Third-party-owned systems, meaning solar leases and power purchase agreements, still qualify for a 30% tax credit in 2026. It’s just a different credit. Section 48E is a commercial investment tax credit, and because the installer or leasing company owns the equipment, they claim it. The savings theoretically flow to you through lower monthly lease rates or PPA pricing. NuWatt’s analysis from June 2026 lays this out clearly: the 48E credit remains available through at least end of 2027, and companies marketing leases are already using it as a selling point.
The catch, and there are a few, is that you don’t own the system. You can’t claim depreciation. You may face complications when you sell your house. And the “savings passed to you” claim deserves serious scrutiny. Get a quote in writing that shows you exactly what rate you’re locking in, what escalator clauses apply year over year, and what happens at lease end. I’ve seen 20-year agreements with 2.9% annual escalators that look fine on day one and ugly by year 12.
That said, for renters-turned-homeowners with no federal tax liability, or anyone who simply can’t absorb a $20,000+ upfront cost, the lease/PPA structure is now genuinely more competitive relative to ownership than it’s been in years.
The Buy vs. Lease Math Has Shifted

Before December 31, 2025, the standard advice was almost always: buy if you can, because the 30% credit made ownership the clear financial winner for anyone with sufficient tax appetite. That calculus is more complicated now.
| Factor | Cash/Loan Purchase (2026) | Lease / PPA (2026) |
|---|---|---|
| Federal tax credit | $0 | 30% (claimed by installer, passed through pricing) |
| System ownership | Yes | No |
| Maintenance responsibility | Yours | Installer’s |
| Home sale complication | Minimal | Can complicate transfer |
| Long-term savings potential | Higher (if system performs) | Lower, but more predictable |
| Upfront cost | $18,000-$30,000+ typical | $0 to low |
| State/utility incentives | You keep them | May be split or retained by installer |
The honest answer is that the right choice depends heavily on your state, your utility, and your tax situation. In states with strong net metering, solid state credits, or both, ownership can still pencil out well even without the federal credit. In states where net metering has been gutted, the math gets harder.
State Incentives Are Now Carrying More Weight

This is where the research gets genuinely uneven, because state programs are a patchwork and they change constantly. But a few worth knowing about as of mid-2026: New York’s 25% state credit (capped at $5,000) survived the federal changes untouched. California’s SGIP battery storage rebate program has been refunded repeatedly and is still active for storage-paired systems. Massachusetts still has its Solar Tax Credit (15%, capped at $1,000, which is modest but real) plus the SMART program for production-based incentives. Texas has no state income tax, so no state solar credit, but some utilities offer rebates and property tax exemptions on added home value from solar remain strong.
The GreenLancer analysis from July 2026 makes the point that savvy shoppers in 2026 need to layer their incentives: state credits, utility rebates, net metering value, and property tax exemptions, because the federal piece is simply gone for buyers. That layering approach is something I’d have called belt-and-suspenders advice before. Now it’s the strategy.
The Battery Story Is Quietly Becoming the Real Story
What surprised me most in the Q1 2026 data wasn’t the credit expiration fallout. It was the battery numbers. Nearly half of all new residential solar systems installed in Q1 2026 included battery storage, a record attach rate. That’s not coincidence. Utility rates have climbed enough in enough markets that the payback math on storage is tightening, and grid reliability concerns are real in places like Texas, California, and the Southeast.
The broader storage market reflects this. Wood Mackenzie and the American Clean Power Association reported 3.3 GW and 8.4 GWh of total energy storage deployed in Q1 2026 alone, with all three segments setting quarterly records, per Utility Dive’s June 2026 coverage. Residential was part of that record sweep.
If you’re buying solar in 2026, the battery question deserves a real answer, not a sales pitch. Get quotes with and without storage. Run the numbers on your specific utility’s time-of-use rates.
What to Actually Do Right Now
Don’t let the absence of the federal credit be the reason you either rush into solar or abandon it. The credit was never the whole story; it was a subsidy that made a good deal better. In some markets, solar still makes strong financial sense without it. In others, the numbers were always marginal and the credit was covering a lot of sins.
Find an installer who’ll give you a quote broken down without assuming any federal credit. Ask specifically what state and utility incentives apply to your address. If they can’t tell you, find someone who can. And if a lease or PPA company is leading with “you still get the 30% credit,” make them show you exactly how that flows through to your actual monthly rate. The credit exists. Whether it benefits you specifically, in a specific contract, is a different question entirely.
