Is Solar Still Worth It in 2026 Without the 30% Tax Credit?

The biggest change to home solar in over a decade happened quietly on December 31, 2025 — the day the 30% federal residential solar tax credit (Section 25D) expired under the One Big Beautiful Bill Act. For roughly fifteen years that credit was the single most-quoted number in every solar pitch: "Get 30% back from the government." In 2026, for any system you own yourself — cash, loan, or any other self-owned structure — that money is gone.

So homeowners are rightly asking the obvious question: without the tax credit, is solar still worth it?

The honest answer is that for many homes it still is — but the smart way to go solar has changed. Here is the real 2026 math, with no spin.

What actually expired (and what didn't)

Two different tax credits get lumped together as "the solar tax credit," and only one of them ended:

• Section 25D — the residential credit. This is the one you claimed on your own tax return when you owned the system yourself — cash, loan, or any other self-owned structure. Congress terminated it for expenditures made after December 31, 2025 (26 U.S.C. §25D(h), as amended by P.L. 119-21 §70506(a)), and an expenditure counts as made when the original installation is completed — so paying in 2025 for a system finished in 2026 does not preserve it. If you own your system in 2026, there is no 30% personal credit. One thing that did survive: if your install was completed in 2025 and the credit was larger than your tax bill, the unused amount still carries forward to later years — a question for your CPA.
• Section 48E — the commercial credit. This still exists for businesses that own energy equipment. It matters to you because a solar lease or power-purchase agreement (PPA) is a third-party-owned system — the financing company owns the panels and is the taxpayer, not you. Whether a provider actually qualifies for that credit on a residential roof is an unsettled question (§50(b)(2) denies the investment credit for property used predominantly to furnish lodging, and how far the "energy property" carve-out reaches into §48E residential solar has never been resolved) — that is the provider's problem, not yours. Nothing from it lands on your tax return. Any value the provider chooses to pass along shows up only in the monthly payment it quotes you, which is a price the provider sets.

That second point is the part homeowners get sold wrong: the credit did not "move" to you. Whatever the owner of the panels does or does not get, the only number that ever reaches you is the monthly payment the provider quotes — a price it sets, not a credit you receive.

Solar savings were never really about the credit

The tax credit lowered your upfront cost. But the reason solar saves money year after year is much simpler: you stop renting electricity from a utility whose rates only go up.

Residential electricity prices have climbed roughly 4–8% a year in most markets, and faster in places like California, Hawaii, and the Northeast. When you produce your own power, you swap a bill that rises forever for an energy cost that is either fixed or eliminated. Over 25 years, that avoided-rate math is far larger than any one-time credit ever was.

The 2026 math: cash, loan, or lease

Cash purchase. You own the system outright and your electricity is essentially free after payback. Without the 25D credit, your upfront cost is higher and your payback period is longer than it was in 2025 — typically a few years longer. Still the best lifetime ROI if you have the cash and plan to stay in the home long-term.

Solar loan. $0 down, you own the system, and you swap your utility bill for a loan payment. Without the credit, loan terms are less aggressive than the old "re-amortize after your 30% check" pitch — so be skeptical of any 2026 quote that still assumes a tax-credit paydown. Honest loan math in 2026 is about whether the payment beats your (rising) utility bill.

Lease / PPA — what you are actually buying in 2026. With a $0-down lease or PPA, the provider owns the system, handles maintenance and monitoring, and sells you the power at a rate it sets — often below what your utility charges today. You get no federal tax credit and nothing goes on your return; whether the provider can claim one is the provider's issue, not a benefit you receive. And the rate is only "locked" if the contract carries a 0% escalator — many step up 2–3% every year, and that single line decides whether you are still saving in year 15 and year 25. Read it before you read anything else on the page.

When solar still makes sense in 2026

• Your monthly electric bill is $120+ and climbing.
• Your utility raises rates most years (almost all of them do).
• You have a reasonably sun-exposed roof and plan to stay a few years or more.
• You want predictable energy costs and, ideally, backup power.

When it might pay to wait

• Your bill is very small (under ~$60/mo).
• You are moving within a year or two.
• Heavy, unavoidable shade over most of your roof.

The bottom line

The end of the 30% residential credit did not kill home solar — it changed the winning move. In 2026, plenty of homeowners still come out ahead going $0-down with a lease or PPA — but only when the quoted rate genuinely beats their utility and the escalator is low or zero. That payment is a price the provider sets, not a tax credit passed down to you.
