Is Solar Worth It in Texas in 2026? An Honest Cost Reality Check
Last updated: October 18, 2026 · 6 min read
Rooftop solar can still pencil out for some Texas homes in 2026 — but the math changed in a big way this year, and much of the advice online hasn't caught up. Before you put money down, it helps to know what moved, what still works in your favor, and how to run the numbers honestly for your own roof.
The short answer
It depends — and more than it used to. The 30% federal tax credit for a system you buy expired at the end of 2025, so an owned system in 2026 costs roughly 30% more out of pocket, which stretches the payback. Texas also has no net metering, so exported surplus earns less than it would in many states. Solar can still make sense with heavy summer AC use and good sun — but the case is tighter now, so run your own numbers rather than a calculator built for the credit era.
The Big 2026 Change: The Federal Tax Credit Is Gone
For years, the biggest reason rooftop solar penciled out was the federal residential solar tax credit — Section 25D — worth 30% off the cost of a system you bought. As of 2026, that credit is gone: it expired at the end of 2025, and homeowners who buy and own a system this year or later generally cannot claim any federal tax credit on it. Losing that 30% effectively raises the net cost of an owned system by about 30% versus a 2025 purchase, which means a longer payback. It also means much of the "solar math" online still quietly subtracts 30% and is now out of date.
Beware solar math that still assumes the 30% credit
Many online calculators and installer worksheets still auto-subtract the 30% federal credit. For a system you buy and own in 2026, that credit is gone, so anything that still applies it overstates your savings. Ask every installer to show the price and payback with no federal tax credit included.
What About $0-Down Leases and PPAs?
One nuance worth knowing: the expiration applies to systems you buy. Third-party-owned systems — solar leases and power purchase agreements (PPAs) — fall under a different part of the tax code (Section 48E) and stay eligible for a credit through 2027. The catch is that the leasing company, not you, claims it. That's why some "$0-down" offers still look attractive: a credit is baked into their pricing. But with a lease or PPA you don't own the panels, you're locked into a long-term contract, and the lifetime economics differ from owning.
Texas Has No Net Metering — So Exports Are Worth Less Here
Texas is different from the states where solar shines brightest, because it has no statewide net metering. In net-metering states, every kilowatt-hour you export spins the meter backward at full retail value. Here, you're paid for surplus through a retail provider's "solar buyback" plan at a rate usually below what you pay for power. So the power your panels make while you're home is worth your full retail rate, while surplus sent to the grid is worth less. Those plan details matter — see our guide on how Texas solar buyback plans work for the full picture.
What Still Works in Solar's Favor in Texas
None of this makes solar a bad idea in Texas — the case just rests on different strengths. The state has strong, consistent sun and brutal summer cooling loads, and a system sized to your daytime and air-conditioning usage can offset a lot of your most expensive summer power. Because that self-used power is worth your full retail rate, it's the part of solar that pays off best here.
Texas law helps in a quieter way too: it exempts the added home value from solar from property tax, so panels generally won't raise your property-tax bill even as they lift your home's value. Some municipal utilities and co-ops — think Austin Energy or CPS Energy, which aren't part of the deregulated market — also offer their own local rebates worth checking. Backup during outages is a separate draw, and a home battery deserves its own look.
The Payback Math in 2026 — Run Your Own Numbers
So what's the payback in 2026? There's no single honest number; anyone quoting one without seeing your roof and bills is guessing. With no federal credit and below-retail export rates, simple payback in Texas today is generally longer than the "7 to 10 years" common in the credit era, often into the low-to-mid teens, depending on your system price, usage, and buyback rate. To size it up yourself, estimate your yearly savings as the power you'll use directly (at full retail) plus the smaller value of what you'll export (at the buyback rate), then divide your net system cost by that figure, using real quotes and your real usage, not a national average.
How to Pencil It Out for Your Home
If you're seriously weighing it, a few steps keep you honest. Size the system to your daytime and AC usage rather than trying to zero out your whole bill. Get two or three itemized quotes and confirm none assume a federal credit for a system you own. Compare the buyback rate across providers, and decide whether backup power justifies a battery's added cost.
Finally, weigh the whole thing against a much cheaper baseline: locking a competitive fixed rate and making a few efficiency upgrades. Better insulation, a smart thermostat, or a higher-SEER AC costs a fraction of a solar array up front and starts trimming your bill right away. Solar may still win for your home — but it should have to beat that baseline, not just look good against a credit-era calculator.

Can I still get the 30% federal solar tax credit in Texas in 2026?
Generally no, not for a system you buy. The 30% federal residential solar credit (Section 25D) expired at the end of 2025, so homeowners who purchase and own a system in 2026 or later cannot claim it. One exception: third-party-owned systems — solar leases and PPAs under Section 48E — stay eligible for a credit through 2027, but the leasing company claims it, not you.
What is the payback period for solar in Texas in 2026?
There is no single honest number — it depends on your system price, your usage, and your buyback rate. But with the federal credit gone and Texas export rates below retail, simple payback today is usually longer than the 7-to-10-year figures from the credit era, often into the low-to-mid teens of years. The only reliable estimate comes from real quotes run against your own usage.
Does solar increase my property taxes in Texas?
No. Texas offers a solar property-tax exemption, so the added home value from a solar installation is exempt from property tax. Your home may be worth more with panels, but that added value generally will not raise your annual property-tax bill.
Is it better to buy solar or lease it in Texas?
They are different trade-offs, not a simple better-or-worse. Buying means you own the system and keep all the savings, but as of 2026 you get no federal credit and pay the full cost up front. A lease or PPA is usually $0 down and can still reflect a credit the company claims, but you do not own the panels and commit to a long-term contract with different lifetime economics. Compare both on equal terms.
