Solar Tax Credits After 2025: The Complete Transition Guide

If you've heard that solar tax credits are "gone," you're only hearing half the story. The federal tax credit for owning a solar system — Section 25D — did expire under the One Big Beautiful Bill Act (OBBBA). But a separate 30% credit, Section 48E, is still available for projects that begin construction before July 4, 2026, and it's what keeps solar affordable for millions of homeowners today. The difference is that 48E flows through leases and Power Purchase Agreements (PPAs) instead of your personal tax return. This guide explains exactly what changed, what survived, and what it means for your wallet.

The Big Question: Did Solar Tax Credits Expire?

Search for "solar tax credits 2026" and you'll find conflicting answers. Some sources say the 30% credit is dead; others say it's alive and well. Both are technically correct, because there were always two separate 30% federal solar credits operating in parallel:

• Section 25D — the Residential Clean Energy Credit, a personal tax credit for homeowners who owned their system.
• Section 48E — the Clean Electricity Investment Credit, a business/investment credit claimed by the system owner.

The OBBBA killed 25D. It did not kill 48E. The result is that the path to a 30% incentive shifted from ownership to leasing. If you're willing to use a lease or PPA, the economics of solar in 2026 are remarkably close to what they were before — sometimes better, because you no longer need a large tax bill to benefit. This is the core of the post-2025 transition, and the source of most of the confusion online.

Why Section 25D Expired

Section 25D was the Residential Clean Energy Credit. For years it returned 30% of a homeowner's solar system cost as a non-refundable personal income tax credit. On a $30,000 system, that was $9,000 back at tax time. It was the single biggest driver of residential solar adoption in the United States.

The One Big Beautiful Bill Act (OBBBA), signed in 2025, terminated 25D for systems placed in service after the law's cutoff date. The policy rationale was twofold: budgetary cost (25D was one of the more expensive individual tax expenditures) and a philosophical shift toward technology-neutral, emitter-based incentives rather than consumer-facing credits. Whatever the politics, the practical effect is clear: if you buy and own a residential solar system today, there is no longer a federal income tax credit available to you personally.

It's important to understand what 25D's end does not mean. It does not make solar illegal. It does not affect state incentives, net metering, or local rebates. It does not touch the 48E credit. And it does not retroactively take away credits from systems that were already placed in service before the cutoff. It simply removes the ownership-based federal tax credit going forward — which is why the lease and PPA market has stepped in to fill the gap.

Section 48E: The Credit That's Still Alive

Section 48E — the Clean Electricity Investment Credit — is a 30% federal tax credit for qualifying clean electricity facilities, and it remains available for projects that begin construction before July 4, 2026 (after that date, new projects no longer qualify). Critically, 48E is a technology-neutral credit: any zero-emission electricity generator that meets the requirements qualifies, including residential-scale solar installed under a lease or PPA.

Here's the key structural difference from 25D: 48E goes to the owner of the system, not the occupant of the home. In a lease or PPA, the solar company (or its financier) owns the equipment on your roof. That company is a commercial entity that can fully use a 30% investment credit against its tax liability — something many individual homeowners struggled to do with 25D, since 25D was non-refundable and capped at your tax liability.

So the 30% incentive didn't disappear; it migrated. Under the old 25D world, you claimed it yourself. Under the 48E world, the financier claims it and you capture the value indirectly through lower monthly payments. In practice, competitive pressure in the solar industry means most of that 30% gets passed through to the customer — because the company that offers the lowest monthly payment wins the deal.

How Leases and PPAs Pass the Savings to You

When a solar financier claims the 48E credit on your system, it lowers their effective cost of installing that system by roughly 30%. To win your business, they pass most of that saving through in the form of lower payments. Two structures dominate the market:

• Solar lease: You pay a fixed monthly amount to rent the system, typically $0 down. The financier owns and maintains the panels. Your monthly payment is set well below what you'd otherwise pay the utility.
• Power Purchase Agreement (PPA): You pay only for the kilowatt-hours the system produces, at a per-kWh rate below your utility rate. Again, $0 down, and the financier owns the equipment.

The result in both cases is immediate positive cash flow: from day one, your combined solar + utility bill is lower than your old utility-only bill. You also get the benefit of the 48E credit without needing any tax liability of your own — a major advantage over the old 25D, which left lower-income and retired homeowners unable to use the full credit. Industry data shows typical lease and PPA customers pay 20-40% less per month than their previous utility bills, with no maintenance costs and full warranty coverage for the lease term.

Lease vs. PPA: Which Structure Fits You?

The choice between a lease and a PPA usually comes down to predictability versus production risk. A lease locks in a fixed monthly payment regardless of how much sun your roof gets, which is appealing in cloudy regions or if you value budget certainty. A PPA ties your bill directly to output, so in a high-production month you pay a bit more (but still at a steep discount to the utility), and in a low-production month you pay less. Both typically run 20-25 years, both are $0 down, and both let you purchase the system at the end of the term or roll it into a home sale.

One detail to scrutinize in either contract is the escalator — a built-in annual rate increase, often 2-3.9% per year. A lower escalator saves you more over the life of the agreement. The 48E credit the financier receives is already baked into your starting rate, so competitive quotes from multiple installers are the best way to ensure you're capturing the full value of that 30% incentive rather than leaving it with the financier.

Real Dollar Comparison

Let's put real numbers on a typical $30,000 residential solar system, before and after the transition:

Scenario	Credit Path	Out-of-Pocket	Monthly Cost	Status
Owned system (25D)	$9,000 personal tax credit	$21,000 net	Loan ~$180/mo (after credit)	Expired
Lease (48E)	Financier claims 30%	$0 down	~$150/mo	Available
PPA (48E)	Financier claims 30%	$0 down	~$0.16/kWh vs ~$0.26 utility	Available

Compared against a typical utility bill of around $200/month, both the lease and PPA deliver roughly $50/month in immediate savings with no upfront cost. The owned-system path used to deliver a larger long-term return (because you eventually owned the asset outright), but that path no longer carries a federal credit — making the $0-down lease/PPA route the most accessible way to capture the remaining 30% incentive after 2025.

What Homeowners Should Do Now

If you're considering solar in 2026 or beyond, the smart move is to shop the lease and PPA market seriously rather than assuming ownership is the only option. Three concrete steps:

1. Get multiple quotes from installers that offer both leases and PPAs — pricing and terms vary widely, and the 48E pass-through differs by company.
2. Compare your financing options side by side using real numbers. Our financing comparison tool does exactly this.
3. Read the fine print on escalator clauses (annual rate increases), system purchase options, and what happens at the end of the term — these matter more than the headline monthly payment.
