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

If you've been sitting on the fence about going solar, you've probably heard the news: the federal residential solar tax credit — that juicy 30% discount that knocked thousands off the cost of a new system — expired on December 31, 2025. Gone. Done. Not coming back anytime soon.

And the phone calls we've been getting at Hartbeat Energy since January? A lot of them start with some version of "Well, I guess I missed the boat."

Here's the honest answer: you didn't miss the boat. The math changed, yes. The payback period got a bit longer. But for most Houston homeowners, solar still makes strong financial sense in 2026 — and in some ways, the conversation has actually gotten cleaner now that one big variable is off the table.

Let me walk you through the real numbers, what incentives are still available right here in Texas, and how to figure out if solar makes sense for your specific situation.

So the Federal Solar Tax Credit Is Really Gone?

Yes. The Section 25D residential clean energy credit — which let homeowners deduct 30% of their entire solar installation cost directly from their federal income tax bill — expired at the end of 2025. Congress did not renew it. If you install a solar system on your home starting January 1, 2026, you get zero federal tax credit for it.

To put that in dollar terms: a typical 10 kW system in the Houston area cost around $21,600 installed before incentives. That 30% credit would have been worth $6,480. That's real money — about what a lot of Houstonians put in savings in a year. Its absence matters.

But before you close the browser, here's the thing most people don't realize: the 30% credit was a federal subsidy layered on top of an already-solid economic case for solar in Houston. The fundamentals that make Houston one of the best solar markets in the country haven't changed at all.

Houston's Solar Math Still Works — Here's Why

Houston gets approximately 5.5 peak sun hours per day on average — some of the best solar production potential in the entire country. Compare that to Boston at 3.8 hours or Seattle at 3.5 hours. Every kilowatt of panel you install here generates significantly more electricity than the same panel installed up north.

We have over 200 days of sunshine a year. Even in January, Houston averages 4.8 peak sun hours. The sun isn't going anywhere, and it still doesn't send a monthly bill.

What Does a System Actually Produce Here?

A well-designed 10 kW system on a south-facing Houston roof will generate roughly 16,000–17,500 kWh per year. The average Houston household uses about 18,888 kWh annually — one of the highest in the country, largely thanks to our summers. A 10 kW system offsets roughly 85–90% of that usage, meaning you're buying very little electricity from CenterPoint's grid.

CenterPoint Electricity Rates in 2026

This is where it gets real. If you're in CenterPoint Energy's delivery territory — which covers most of Houston and Harris County — your actual electricity cost isn't just the energy charge. It's the energy charge plus CenterPoint's delivery charge, which has steadily climbed over the past few years.

That all-in rate is what solar actually offsets — and it's meaningfully higher than the raw energy rate. When your solar panels generate a kWh, you're not just saving the commodity price of electricity. You're saving delivery charges too. That math matters a lot for calculating real payback.

What Texas Incentives Are Still Available in 2026?

Even without the federal residential credit, Texas homeowners have access to genuine financial incentives that most other states don't offer. Here's what's still on the table.

1. Texas Property Tax Exemption (This One Is Huge)

Under Texas Tax Code Section 11.27, the added value that solar panels add to your home is 100% exempt from property taxes. This is a permanent state exemption, and it's one of the most underappreciated solar benefits in Texas.

Solar typically increases Houston home values by $15,000–$20,000. Without the exemption, you'd owe property taxes on that added value every single year. In Harris County, where the effective property tax rate hovers around 2.2–2.4%, that's $330–$480 per year in property tax you'd never owe — for as long as you own the home.

Over 25 years, that exemption alone is worth $8,250–$12,000 in after-tax savings. It's real money, and it goes away if you sell to someone who doesn't apply for it.

2. Texas Sales Tax Exemption

Solar equipment and installation in Texas is exempt from the state sales tax (currently 8.25% in most of Harris County). On a $21,600 system, that's roughly $1,780 in tax you simply don't pay at purchase. This is baked into the installer's price — you don't have to do anything to claim it.

3. Solar Buyback Plans Through ERCOT Retail Providers

Texas doesn't mandate net metering — CenterPoint is under no obligation to buy your excess solar power. But because Houston operates in the deregulated ERCOT electricity market, you have the freedom to shop for a retail electricity provider that does offer solar buyback plans.

Several retail electric providers (REPs) operating in Houston's CenterPoint territory offer plans that credit your account — at varying rates — for every kWh your panels send back to the grid. The credit rates and structures vary widely, so it pays to compare plans when you go solar. We help our customers with this analysis as part of every installation.

Buying vs. Leasing Solar in 2026 — Which Makes More Sense Now?

The expiration of the residential ITC has actually shifted the lease vs. buy calculation in an interesting way.

If you're planning to stay in your Houston home for 10+ years and you can handle either a cash purchase or a solar loan, buying still delivers significantly more lifetime value. A purchased system pays itself off and then runs as a free electricity source for 15–20 more years. That's $40,000–$70,000 in electricity you never buy from CenterPoint.

Leasing makes more sense if you're cash-flow constrained, unsure about your timeline, or primarily want to lower your monthly bill without a big upfront commitment. The installer passing through part of their commercial ITC savings means lease economics actually improved slightly relative to purchase economics in 2026 — an unusual situation that's worth understanding.

The Updated Numbers: Payback Period Without the Federal Credit

Let's look at an honest example for a typical Houston homeowner in Katy, Pearland, or Sugar Land — places where we install a lot of systems and where average electricity usage runs high due to larger homes and long cooling seasons.

Houston Weather: Why Durability Still Matters More Than Subsidies

Here in Houston, there's a solar factor nobody talks about enough: hurricane season. We run from June 1 through November 30, and that shapes everything about how a solar system should be designed and installed.

Modern solar panels are tested to withstand 130+ mph winds when properly mounted, and installers using IBC 2021 racking standards on Houston roofs are building systems that can handle Category 3 hurricane-force conditions. The panels themselves often survive storms far better than the roofs beneath them.

Summer in Houston also means your AC is running hard from April through October — exactly when your solar panels produce the most power. The alignment of peak solar production with peak electricity demand is one of the most underrated financial advantages of Houston solar. Your highest-value production hours overlap almost perfectly with your highest electricity usage hours.

And for homeowners who've experienced a CenterPoint outage — whether from a hurricane, a winter freeze, or a summer storm — this is also where battery backup conversations start. A solar-plus-battery system keeps your critical circuits running when the grid goes down. That's a separate conversation, but it's worth knowing that adding a battery to a solar system doesn't require the residential ITC to pencil out financially, given Houston's outage history.

What About HOA Restrictions on Solar in Houston?

If you live in a master-planned community in The Woodlands, Sugar Land, Katy, or League City — and plenty of Houston homeowners do — you may have been told your HOA can block solar panels. That's not accurate under current Texas law.

Texas Property Code Chapter 202 significantly limits what HOAs can do to restrict solar. An HOA cannot effectively prohibit solar panels, though it can impose reasonable restrictions on placement (like preferring rear-facing panels over front-facing when the roof configuration allows). They cannot require you to use materials or placements that meaningfully reduce your system's performance or add more than 10% to the cost.

In practice, the vast majority of Houston-area HOA solar issues we encounter are resolved with a simple application and a set of engineering drawings. It's paperwork, not a roadblock. We handle this process with our customers regularly in Sugar Land, Cinco Ranch, and Bridgeland subdivisions.
