Texas's solar picture in 2026 is complicated by one fundamental tension: the state has excellent sun but no statewide net metering. That means what your system produces and what you actually earn from it can be very different numbers depending on which utility serves your home. The honest payback range is 12–16 years for most ERCOT customers — but there are real exceptions worth knowing.

Key Takeaways
- A typical 9 kW Texas system costs ~$22,500 at $2.50/watt (LBNL 2024) — no federal 25D credit applies
- Austin Energy's Value of Solar tariff pays $0.097/kWh for exports — far better than most ERCOT territory
- Texas averages 5.5–6.0 peak sun hours/day, producing roughly 17,600–19,200 kWh/year for an 8 kW system
- 100% property tax exemption on solar added home value (Texas Tax Code §11.27) applies statewide
Texas Solar Costs in 2026
At $2.50/watt, Texas is one of the most affordable solar markets in the country — roughly 10% below the national median. A 9 kW system for a typical Texas home costs approximately $22,500 before any incentives. With 5.5–6.0 peak sun hours per day across most of the state, that system produces roughly 17,600–19,200 kWh annually — enough to cover a significant portion of the average Texas home's 14,000+ kWh annual usage.
There is no Texas state income tax credit for solar and no statewide rebate program outside specific utility territories.
| System Size | Cost at $2.50/W | Annual Production (5.7 hrs avg) | Annual Savings at $0.131/kWh (self-use) |
|---|---|---|---|
| 7 kW | $17,500 | ~14,600 kWh | ~$1,913 |
| 9 kW | $22,500 | ~18,800 kWh | ~$2,463 |
| 11 kW | $27,500 | ~22,900 kWh | ~$2,999 |
These savings figures assume high self-consumption. In deregulated ERCOT territory where export rates are low, every kWh exported instead of consumed directly costs you real money in lost value.
The Export Rate Problem
Texas has no statewide net metering law. Each utility sets its own policy. That single fact is the biggest driver of solar economics in Texas — more than sun hours or install cost.
| Utility / Territory | Export Policy | Export Rate | Estimated Payback (9 kW) |
|---|---|---|---|
| Austin Energy | Value of Solar tariff | $0.097/kWh | ~10–12 years |
| CPS Energy (San Antonio) | Avoided cost + rebate | ~$0.05–$0.07/kWh | ~12–14 years |
| ERCOT deregulated (most of TX) | Varies by retail provider | $0.03–$0.07/kWh | ~13–16 years |
| El Paso Electric | Full retail net metering | ~$0.131/kWh | ~9–11 years |
Austin Energy's Value of Solar tariff at $0.097/kWh is a standout. It's not full retail, but it's close enough that Austin homeowners get meaningfully better economics than the typical ERCOT market.
Austin Energy: The Best Texas Solar Market
If you're in Austin Energy's service territory, you're in Texas's best solar market. Austin Energy pays $0.097/kWh for every kWh your system produces under their Value of Solar tariff — not just exported kWh, but all production. That's combined with a $2,500 rebate for qualifying systems.
According to Lawrence Berkeley National Laboratory's Tracking the Sun 2024, Texas's average install cost of $2.50/watt is one of the lowest in the nation, making Austin Energy's combination of low system cost, solid sun, and a reasonable export rate the foundation for 10–12 year payback periods.
On a 9 kW system producing 18,800 kWh/year:
- Austin Energy Value of Solar payment: 18,800 × $0.097 = $1,824/year
- Less $2,500 rebate on install
- Net system cost after rebate: $20,000
- Payback: approximately 11 years
Texas Property Tax and Sales Tax Exemptions
Texas's state-level incentives are tax-exemption-based rather than tax-credit-based — but they're real and apply statewide.
Property tax exemption (Texas Tax Code §11.27): Solar installations are 100% exempt from property tax assessment. If your system adds $20,000 to your home's value, that $20,000 is completely excluded from your tax bill permanently. At Texas's average effective property tax rate of ~1.6%, that's approximately $320/year in avoided property taxes — a meaningful ongoing benefit over a 25-year panel lifespan.
Sales tax exemption: Solar equipment is exempt from Texas state sales tax (6.25%), plus most local sales taxes. On a $22,500 system, that saves roughly $1,800–$2,000 upfront.
These two exemptions together represent approximately $1,800 upfront plus $320/year ongoing — not a replacement for a strong net metering policy, but a real reduction in true system cost.
Is Battery Storage Worth It in Texas?
For ERCOT market homeowners with poor export rates, battery storage changes the math significantly. Instead of exporting midday solar at $0.03–$0.07/kWh, you store it in a battery and use it in the evening at the full $0.131/kWh retail rate.
The gap between export value ($0.05/kWh typical) and retail value ($0.131/kWh) is $0.081/kWh. On 5,000 kWh of annual battery cycling, that's $405/year in additional value captured. Given Texas's storm vulnerability and grid instability (Winter Storm Uri, 2021), many Texas homeowners value backup power independently of the financial return.

What to Do Next
Identify your utility and its exact export rate.
In deregulated ERCOT territory, your retail electricity provider may or may not credit solar exports — and rates vary widely. Call your provider or check your plan's Electricity Facts Label (EFL) for solar buyback terms before sizing your system.
Calculate your self-consumption ratio.
Review your hourly usage data (available in your utility’s online portal or on a smart meter) to see how much of your electricity use falls during daylight hours. Higher daytime use = more self-consumption = better economics regardless of export rate.
Run your personalized ROI with your actual numbers.
Texas’s wide range of utility programs means statewide averages are almost useless for your decision. Enter your ZIP code, monthly kWh usage, and export rate to get a number that reflects your actual situation.
Get three competing quotes from Texas-based installers.
Texas has a large installer market. EnergySage and SolarReviews both show multi-quote users save 15–20% on average. At $2.50/watt, even modest negotiation saves $1,500–$3,000 on a typical system.

Adding an EV? Charging at home during solar hours substantially improves Texas solar ROI by increasing self-consumption. Our Whole-Home Bundle Calculator models the combined solar + EV economics side by side.
Bottom Line
Texas solar in 2026 is viable for the right homeowner — particularly those in Austin Energy territory, those with high daytime electricity use, and those who value grid resilience after Winter Storm Uri. For most ERCOT market customers facing 13–16 year paybacks, it requires confidence you'll stay 12+ years and that electricity rates continue rising. The excellent sun, low install costs, and solid property tax exemption build a real case; the weak export policy is the limiting factor.
