Is solar worth it in Texas? (2026)

Solar in Texas still pencils out over a 25-year horizon — but not for everyone, and not as easily as it did in 2025. With the federal residential tax credit gone, the simple payback on a typical Texas system is now 10–12 years, up from roughly 7–8 years. Whether that works depends on four things: your electricity rate, how your utility handles solar exports, your roof’s sun exposure, and which local incentives you can still claim.

The four factors that determine your payback

Electricity rate: 15.3¢/kWh

Texas sits right around the national average — not the cheapest, not the most expensive. At 15.3 cents per kilowatt-hour, every unit of solar power you consume instead of buying from the grid saves you that amount. Homeowners in states paying 25–30¢/kWh see payback in five years or less; Texas homeowners need strong sun and well-sized systems to compensate for a middling rate.

Sun hours: 5.3 per day

With an average of 5.3 peak sun hours per day, Texas generates substantially more power per watt of panel than homeowners in the Midwest or Pacific Northwest. An 8-kilowatt system here produces roughly 15,500 kWh per year — enough to cover the average Texas home’s annual load and then some.

Net metering: the biggest wildcard

There is no statewide net-metering mandate in Texas. What you get paid — if anything — for power you send back to the grid is entirely up to your utility or retail electricity provider. Austin Energy and CPS Energy offer structured buyback programs at rates that make solar genuinely attractive. Many competitive ERCOT retail providers pay flat bill credits or wholesale prices as low as 3–4¢/kWh — a fraction of the 15.3¢ you pay to buy power. In that situation, every kilowatt-hour you export is worth far less than one you consume yourself. Sizing matters enormously here.

Local incentives: real, but limited

Texas has no state income tax, so there’s no state solar income-tax credit to miss. What does exist is a 100% property-tax exemption on the value that solar adds to your home — a durable, ongoing benefit. Local utility rebates are available through Austin Energy (a $2,500 residential rebate) and a handful of co-ops, but funding is capped and often exhausted early in the year. (CPS Energy’s residential rebate ended in 2022.) See the full current picture at Texas solar incentives.

What losing the federal credit actually costs you

The federal residential solar tax credit (IRC §25D) expired December 31, 2025, under the One Big Beautiful Bill Act. If you installed before that deadline, you claimed 30% back on your federal return. If you’re buying in 2026, your federal credit is $0 — not a technicality, but the law as currently written for homeowners who own their systems.

At $2.60 per watt installed, an 8 kW system costs roughly $20,800 before incentives — get itemized quotes rather than treating this figure as exact. Under the old rules, a 30% credit would have returned approximately $6,240, bringing your net cost to about $14,560. That $6,240 is simply gone. Divided by annual savings of around $2,370, losing the credit adds two to three years to simple payback for a system of this size. Across larger installations or households with lower self-consumption, the impact stretches to three to five years.

If you’re weighing ownership against a solar lease or power purchase agreement, the company that owns the panels under a PPA may still access the commercial clean energy credit (§48E). Competitive providers sometimes pass part of those savings through as a lower rate. Ask about it when comparing options — it’s not a free lunch, but it changes the comparison.

A worked example: 8 kW system in Houston

• System cost: 8,000 W × $2.60/W = $20,800 (estimate)
• Federal credit (2026): $0
• Annual production: 8 kW × 5.3 h/day × 365 days × 0.80 derate = ~12,400 kWh (the 0.80 factor reflects the ~20% real-world loss from heat, wiring, and inverter inefficiency)
• Estimated annual savings at 15.3¢/kWh: ~$1,900 (assumes most power is self-consumed)
• Simple payback: $20,800 ÷ $1,900 = ~11 years
• 25-year net gain (flat rate assumed): ~$26,700 (estimate)

Apply even a 2% annual electricity rate increase — consistent with Texas’s historical trend — and payback shortens by roughly a year. Add the property-tax exemption benefit, which varies by your home’s assessed value and local tax rate, and the 25-year figure improves further.

Net metering in Texas: your utility matters more than your panels

Austin Energy’s Value-of-Solar buyback (~9.9¢/kWh) makes reasonable system sizing — even slight over-sizing — financially viable. CPS Energy credits exports far lower (~2¢/kWh), so San Antonio homeowners should size closer to their own daytime use rather than over-build for export. If you’re on a competitive ERCOT retailer, call them before you buy a single panel. Ask what they pay per kWh for solar exports and whether that rate is guaranteed or subject to change.

If the export rate is poor, a battery changes the calculus. Instead of sending surplus solar to the grid for pennies, a battery stores it for your evening consumption at full retail value. That adds cost — typically $10,000–$15,000 for whole-home storage — but it also protects you during Texas’s notoriously unreliable grid events. In a state where winter storm outages have cost homeowners thousands, resilience has real monetary value beyond the payback spreadsheet.

Who solar is worth it for — and who should wait

Situation	Verdict
High bill ($200+/month), own your roof	Go solar — payback around 10 years, strong 25-year return
Austin Energy customer	Go solar — strong ~9.9¢/kWh Value-of-Solar buyback
Competitive ERCOT retailer, no battery budget	Size to self-consumption only — avoid over-generating
Selling your home in 2–3 years	Wait — you likely won’t recoup upfront cost that quickly
Renting, shaded roof, or short-term owner	Wait or consider a PPA — ownership economics don’t apply
Want resilience from grid outages	Solar + battery — resilience value supplements the financial case
Cash-constrained with high-interest financing only	Wait — interest charges can erase the long-term return

The 25-year picture

Solar panels carry 25-year production warranties for good reason: the long horizon is where the investment pays. At an estimated $1,900/year in savings from an 8 kW system, cumulative savings over 25 years total roughly $47,500 against a $20,800 upfront cost — an estimated net gain of around $26,700 at flat rates. Rates rarely stay flat. At 2% annual escalation, 25-year savings rise to roughly $60,000 and payback shortens to closer to nine years.

Texas’s combination of strong sun and a meaningful property-tax exemption puts it among the better long-term solar markets in the country, even without the federal credit. The jump-start available in 2025 is gone. The fundamentals — sun, rising rates, and a long panel lifespan — remain. Detailed cost breakdowns are at solar panel cost in Texas.

How to move forward

Get at least three itemized quotes — not just a price per watt, but a line-by-line breakdown covering panels, inverter, racking, labor, and permit fees. Ask each installer what your specific utility pays for solar exports and whether they’ve installed for other customers on your exact rate plan. Verify current local rebate availability before signing anything; utility program funding changes without notice, and availability differs by zip code.

Run the solar savings calculator with your last 12 months of electricity bills, your zip code, and your available roof space. The estimate won’t replace a site survey, but it will quickly show whether the numbers are worth pursuing. In Texas in 2026, for the right homeowner on the right utility, they still are.
