Is solar worth it in Texas in 2026? The real debate

There’s a real argument on both sides of Texas solar, and it’s worth having honestly instead of glossing over it. Grid power here isn’t cheap the way it is in the Pacific Northwest, but it’s not the 25–35¢/kWh you’d pay in California or Massachusetts either — Texas sits at 16.99 cents per kWh, right around the national average. Installs, on the other hand, are genuinely inexpensive: $2.60 per watt, among the lower prices in the country. Whichever side of that trade-off wins for you depends on two things nobody can answer from a national average: your specific retail electricity plan, and how much of your own production you’ll actually use versus export.

The case for staying on the grid

Sixteen ninety-nine cents a kilowatt-hour is a middling rate. Homeowners in high-cost states break even on solar in five years or less because every kWh they stop buying is worth 25–35¢. In Texas, that same kWh is worth roughly half as much, so the savings side of the equation grows more slowly. Layer on the fact that Texas has no statewide net-metering mandate — what you’re paid for exported power depends entirely on your utility or retail provider — and it’s easy to end up on a plan that pays wholesale-level rates of 3–4¢/kWh for anything you send back. If that’s your situation and you oversize your system, a meaningful share of your production is worth almost nothing. That’s the strongest argument for waiting or, at minimum, sizing conservatively.

The case for buying anyway

Now the other side. At 5.3 peak sun hours per day, Texas panels produce substantially more power per watt than an identical system in the Midwest or Pacific Northwest — an 8 kW array here generates roughly 15,500 kWh a year, more than enough to cover a typical Texas home’s load. And installs are cheap: at $2.60/W, an 8 kW system runs roughly $20,800 before incentives (get itemized quotes rather than treating that as exact). A 100% property-tax exemption on the added home value is durable and ongoing — no funding cap, no expiration. Austin Energy pays a strong ~9.9¢/kWh Value-of-Solar buyback and still offers a $2,500 residential rebate. Put cheap installs, strong sun, and a fair buyback utility together, and the numbers work even without help from Washington. Full detail on what’s currently available is at Texas solar incentives.

What losing the federal credit changed

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

On that $20,800 system, a 30% credit would have returned approximately $6,240, bringing net cost to about $14,560. That $6,240 is simply gone. Divided against annual savings of around $2,630, losing the credit adds two to three years to simple payback for a system this size — and stretches to three to five years on larger installations or for households with lower self-consumption. If you’re weighing a lease or PPA instead of ownership, the company that owns the panels can still access the commercial §48E credit, and some competitive providers pass part of that through as a lower rate. Worth asking about when you’re comparing quotes.

Running the numbers: an 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, reduced roughly a fifth for real-world losses from heat, wiring, and inverter inefficiency (a 0.80 factor) = ~12,400 kWh
• Estimated annual savings at 16.99¢/kWh: ~$2,100 (assumes most power is self-consumed)
• Simple payback: $20,800 ÷ $2,100 = ~10 years
• 25-year net gain at a flat rate: ~$31,700 (estimate)

A 2% annual electricity rate increase — roughly in line with Texas’s historical trend — shortens that payback by about a year. Add the ongoing property-tax exemption, and the 25-year figure improves further. Run your own address and usage through the solar savings calculator rather than leaning on this single example.

Your utility is the tiebreaker

This is where the debate actually resolves for most homeowners. Austin Energy’s Value-of-Solar buyback (~9.9¢/kWh) makes even a slightly oversized system financially sound — you’re not punished much for overproducing. CPS Energy credits exports far lower, around ~2¢/kWh, so San Antonio homeowners should size close to their own daytime usage instead of building for export. (CPS Energy’s own residential rebate ended in 2022, so don’t count on it in a quote.) If you’re on a competitive ERCOT retailer, call before you commit to a system size — ask what they pay per kWh for solar exports and whether that rate is locked or floating.

Where the export rate is poor, a battery flips the calculus: instead of sending surplus power to the grid for a few cents, you store it and use it in the evening at full retail value. That adds $10,000–$15,000 for whole-home storage, but it also buys real protection during Texas’s grid events — winter storm outages have cost homeowners thousands in the past, and that resilience has value the payback spreadsheet doesn’t fully capture.

Weighing it: ownership pros and cons for 2026

In favor of buying now: a high bill ($200+/month) on your own roof, an Austin Energy account with its strong buyback rate, a genuine want for outage resilience, and a plan to stay put for the long haul — all of these tilt toward solar paying off around the 10-year mark with a strong 25-year return.

In favor of waiting or renting/leasing instead: selling within 2–3 years (you likely won’t recoup the upfront cost that fast), a shaded roof or short ownership horizon, only high-interest financing available (the interest can erase the long-term gain), or a competitive ERCOT plan with a poor export rate and no budget for a battery — in that last case, at minimum size the system to your own consumption rather than for export.

The 25-year picture

At an estimated $2,100 a year in savings, a Texas 8 kW system produces roughly $52,500 in cumulative savings over 25 years against $20,800 upfront — a flat-rate net gain around $31,700. Rates rarely stay flat: at 2% annual escalation, 25-year savings climb to roughly $66,500 and payback shortens to closer to eight years. Combined with the property-tax exemption, that puts Texas among the better long-term solar markets in the country even without federal help — the fast start from 2025 is gone, but the fundamentals of sun, rising rates, and a 25-year panel lifespan haven’t moved. Detailed cost breakdowns live at solar panel cost in Texas.

How to settle the debate for your own roof

Start with the question that decides everything in Texas: what does your retail plan actually pay for exported power? Get that figure in writing from your provider before you talk to a single installer, because it determines whether the pro-solar or pro-grid side of the debate wins at your address. When you do collect bids, insist that each one separates equipment, labor, and permitting costs — a single bottom-line price makes competing offers impossible to compare — and ask whether the company has built systems for customers on your exact retail plan. Rebate funding at the utility level comes and goes without notice, so confirm availability the same week you sign, not the week you first got the quote. The solar payback calculator can referee the debate in a few minutes once you feed it a year of real bills.
