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

The short answer: yes, home solar is still worth it in 2026 for many US homeowners — but the answer is now "it depends on your state." The 30% federal tax credit is gone for people who buy with cash or a loan, which makes payback meaningfully longer. At the same time, rising electricity rates and strong state net-metering keep solar penciling out in plenty of places — and clearly not worth it (yet) in a few low-rate, weak-incentive states. Below is exactly how to tell which camp you're in.

What actually changed in 2026

The federal Residential Clean Energy Credit (Section 25D) — the 30% credit homeowners have leaned on for years — is not available for any property placed in service after December 31, 2025. If you buy a home solar system with cash or a loan in 2026, your federal residential credit is $0, down from 30%.

The statute is explicit: the credit "shall not apply with respect to any expenditures made after December 31, 2025" (26 U.S. Code § 25D(h)). And the timing rule matters — under Section 25D(e)(8)(A), the IRS treats an expenditure as made when the original installation is completed, not when you sign a contract or pay a deposit. So an installation finished in 2026 does not qualify, even if you paid in 2025. As the IRS puts it, simply paying for the property on or before December 31, 2025 is not sufficient if installation is completed after that date (IRS OBBB FAQs).

One caution about the IRS site itself. The live IRS Residential Clean Energy Credit page still carries outdated boilerplate saying you can claim the credit "every year that you install eligible property until the credit begins to phase out in 2033." That line is stale. The same page also states the operative rule: the credit "is not available for any property placed in service after December 31, 2025." That after-2025 cutoff is what's true now.

So does that kill the deal? No — here's why the math still works in many states

Losing a 30% discount obviously hurts. But the credit was a one-time reduction on what you paid. It doesn't change the thing solar does every month for 25 years: offset a power bill that keeps going up.

And that bill is going up. The U.S. average residential electricity price is forecast at 18.2 cents/kWh in 2026, up nearly 5% from the 2025 average of 17.3 cents/kWh, with a further increase forecast for 2027 (EIA Short-Term Energy Outlook, June 9, 2026). That's a forecast of the national average — your own rate may be higher or lower — but the direction matters: every cent your utility rate climbs makes each solar kilowatt-hour more valuable.

So there are two competing forces in 2026. The lost credit raises your net cost. Rising rates raise your annual savings. Whether solar still wins comes down to where you live and how those two forces net out for you.

How solar payback actually works (the math, in plain English)

You don't need a spreadsheet to understand the core idea. Payback is just:

Payback (years) ≈ net system cost ÷ annual bill savings

• Net system cost = what you pay for the installed system. In 2026, with no 25D credit for cash/loan buyers, this number is higher than it would have been in 2025.
• Annual bill savings = (kWh your system produces × your electricity rate), adjusted for how your utility credits the power you export to the grid (your net-metering rule).

So the credit going away pushes payback up, and rising rates push it down. The net effect, across the market, is that payback has gotten meaningfully longer.

How much longer? A market modeling estimate from EnergySage puts it at roughly 43% longer without the credit — on the order of about 11 years with the old credit versus about 15.5 years without (EnergySage). Treat that as a modeled national average, not a universal rule: EnergySage's own state-by-state numbers run from roughly 5–7 years in a high-rate, sunny state to well over 20 years in a low-rate one, so your own figure could land far above or below the average. The only way to get your number is to run your state, rate, and usage — which is what our residential calculator does with 2026 (no-credit) rules baked in.

What moves your payback

Here's how each lever pushes the math — qualitatively, because real dollar figures depend entirely on your state and quotes.

The takeaway: no single number describes "solar payback" anymore. It's the combination of these levers in your specific location.

Why your state is the whole ballgame

Two homeowners can buy the identical system and get very different answers — because the two biggest levers, your electricity rate and your net-metering rule, both vary enormously by state.

The policy spread is real. DSIRE, the national database operated by the N.C. Clean Energy Technology Center at NC State, tracks more than 2,600 incentive and policy entries for renewables and energy efficiency across all 50 states. Export-credit value alone runs from roughly full retail rate in some states down to a few cents per kWh in others — a spread wide enough to swing payback by years.

California is the clearest illustration that policy, not just sunshine, drives the math. Under NEM 3.0 (net billing, effective April 2023), export credits are based on avoided-cost rates that vary by time of day and season and sit far below the old full-retail rate. That lengthens solar-only payback and makes adding a battery much more valuable (EnergySage on NEM 3.0). California still gets plenty of sun — but its net-metering rule changed the answer.

This is why per-state data matters more than one national verdict. See our best states for solar ranking and the full state-by-state index to find where your state sits.

When NOT to buy

Here's when buying solar in 2026 may not be the move:

• You're in a low-rate state with weak net metering and no state incentive. Without the federal credit, your payback may now run longer than you plan to own the home. Waiting, or a lease/PPA, may beat buying outright.
• You're planning to move in the next 5–7 years. A long payback period only pays off if you stay long enough to collect the savings.
• Your roof needs replacement first. Don't mount a 25-year asset on a roof that won't last 10 — handle the roof, then revisit.
• You're in a net-billing state (like CA) and won't add a battery. Solar-only economics there have stretched; a battery often changes the picture, but it adds upfront cost.

None of this means solar is dead. It means the right answer is household- and state-specific — and sometimes that answer is "wait."

The assumptions behind any payback estimate

So you can judge the numbers for yourself, here's what a reasonable model assumes — these are assumptions, not guarantees:

• Panel degradation of about 0.5% per year. That's the median crystalline-silicon degradation rate across roughly 2,000 reported rates in NREL's analytical review, and it lines up with the warranty norm, where module makers commonly warrant that output won't decline more than about 0.5%/year (NREL, Jordan & Kurtz).
• A ~25-year horizon, since production warranties commonly run 25 years.
• Your local electricity rate and your utility's net-metering rule — the two levers that move the answer most.

Your real result depends on your roof, your usage, and the actual quotes you get. Models get you in the ballpark; quotes get you the truth.

How to get YOUR real answer in 2 minutes

Stop reading averages and run your own number. Our residential solar calculator lets you plug in your state, your electricity rate, and your usage, and see your own payback with 2026 rules baked in — meaning no federal credit for cash/loan buyers, your state's incentives, and your net-metering reality.

Be wary of any 2026 offer that promises a 30% federal residential credit: for cash or loan buyers, that credit ended for systems placed in service after December 31, 2025, so it can't be delivered on a 2026 install. (Worth noting: the credit ending is a residential story. The commercial credit under Section 48E survived — a 6% base rate that rises to 30% when a project meets prevailing-wage and apprenticeship rules, which smaller projects under about 1 MW generally get without those steps — and USDA REAP grants are paused in 2026 while guaranteed loans stay open. Relevant if you're a farm or business, which is why we run separate farm and commercial tracks.)

The bottom line

Home solar is still worth it in 2026 for many homeowners — just not all, and no longer everywhere. The 30% credit is gone, payback is longer, and the answer now hinges on your state's rates and net-metering rules more than on federal policy. The fastest way to know your verdict is to run your own numbers.
