Texas has cheap electricity and cheap solar installs — a combination that sounds ideal but actually creates a challenging ROI environment. At $0.131/kWh average (EIA, 2025), there's simply less money to save each month, which stretches payback timelines. That said, Texas's property tax exemption, zero income tax, strong sun in most of the state, and a handful of utility rebate programs make solar viable — you just need to run the numbers honestly.
Disclaimer: Cost estimates are based on Lawrence Berkeley National Laboratory's Tracking the Sun 2024 report and NREL PVWatts data. Electricity rates from EIA Electric Power Monthly.

Key Takeaways
- Texas installs average ~$2.50/watt (LBNL 2024) — a 9 kW system runs ~$22,500 before incentives, with no federal 25D credit
- At $0.131/kWh, low Texas electricity rates extend payback to 11–15 years without utility incentives
- 100% property tax exemption for solar added value is a real benefit — adds $20,000+ in untaxed home equity on a typical system
- Austin Energy and CPS Energy (San Antonio) offer rebates of $2,500–$3,000 that meaningfully improve the math in those cities
- Many Texas utilities offer no net metering or only avoided-cost credits (~$0.04–$0.08/kWh) — check before sizing up
What Does Solar Cost in Texas in 2026?
Texas benefits from a competitive installer market, lower permitting fees than coastal states, and relatively low electrician labor costs. The statewide average sits at approximately $2.50/watt installed according to Lawrence Berkeley National Laboratory — about $0.25/watt below the national median.
| System Size | Gross Cost at $2.50/W | Annual Production (est.) | Notes |
|---|---|---|---|
| 6 kW | $15,000 | ~12,100 kWh/year | Smaller home, low usage |
| 8 kW | $20,000 | ~16,100 kWh/year | Average Texas single-family home |
| 9 kW | $22,500 | ~18,150 kWh/year | Higher usage or EV charging |
| 12 kW | $30,000 | ~24,200 kWh/year | Large home, pool, or multi-EV household |
Production estimates assume 5.5 peak sun hours per day (central Texas average). West Texas (El Paso, Midland) averages 6.0–6.5 peak sun hours, which improves output. East Texas and the Gulf Coast average 5.0–5.5. Use NREL's PVWatts Calculator to get an estimate specific to your ZIP code.
The Texas Net Metering Problem
This is the most important nuance in the Texas solar picture. Unlike states with retail-rate net metering, Texas has no statewide net metering law. Each utility sets its own export policy — and many offer poor terms.
| Utility / Market | Export Policy | Export Rate (approx.) |
|---|---|---|
| ERCOT deregulated (most of Texas) | Retail Provider dependent — varies widely | $0.03–$0.08/kWh avoided cost |
| Austin Energy | Value of Solar Tariff | ~$0.097/kWh (2025–2026) |
| CPS Energy (San Antonio) | Net Metering at avoided cost | ~$0.04–$0.06/kWh |
| Oncor territory (Dallas) | Depends on retail provider | $0.04–$0.07/kWh |
| Entergy Texas (Southeast TX) | Avoided cost | ~$0.04–$0.05/kWh |
The practical implication: in most of Texas, exporting solar to the grid earns very little. A system that produces 20% more than you consume won't earn meaningful export credits — that excess is essentially wasted. This means right-sizing your system to your consumption matters even more in Texas than in states with full retail net metering.
Texas Solar Incentives in 2026
Texas has no state income tax and no state-level solar credit. But it does have meaningful incentive programs through the property tax code and select utilities.
Property Tax Exemption (Section 11.27, Texas Tax Code)
Texas provides a 100% exemption on the added property value from solar under Texas Tax Code Section 11.27. A solar system that adds $20,000–$25,000 to your home's appraised value generates zero additional property tax. At a Texas average effective property tax rate of ~1.6%, that's $320–$400/year in avoided taxes — permanently.
Sales Tax Exemption
Solar equipment in Texas qualifies for a sales and use tax exemption under the Texas Comptroller's rules for pollution control equipment. On a $22,500 system, avoiding the 8.25% sales tax saves approximately $1,856 — a real upfront cost reduction.
Austin Energy Rebate
Austin Energy offers a $2,500 rebate for residential solar systems (as of 2026) through their Austin Energy Solar Rebate Program. This is available to Austin Energy customers only and is paid after inspection and interconnection approval.
CPS Energy (San Antonio) Rebate
CPS Energy has offered residential solar rebates of $2,500–$3,000 for qualifying installations. Check CPS Energy's solar program page for current rebate availability, as funding is limited.
ONCOR and Other ERCOT Utilities
Most ERCOT-territory utilities outside Austin and San Antonio don't offer direct cash rebates. Some retail electricity providers in the deregulated market offer solar buyback plans at better-than-avoided-cost rates — worth shopping around if you're in Oncor, AEP Texas, or Luminant territory.
Where Solar Makes the Most Sense in Texas
Given the combination of low electricity rates and weak net metering in most of the state, solar ROI in Texas depends heavily on where you live and who your utility is.
| City / Utility | Rate (est.) | Export Policy | 8 kW Payback Est. |
|---|---|---|---|
| Austin (Austin Energy) | ~$0.12/kWh | $0.097/kWh Value of Solar | 9–11 years |
| San Antonio (CPS Energy) | ~$0.115/kWh | ~$0.05/kWh avoided cost | 11–14 years |
| Dallas / Fort Worth (ERCOT) | ~$0.135/kWh | ~$0.04–$0.07/kWh | 12–16 years |
| Houston (ERCOT) | ~$0.130/kWh | ~$0.04–$0.06/kWh | 12–15 years |
| El Paso (EPE) | ~$0.125/kWh | Retail net metering | 9–12 years |
El Paso Electric is notable — it's not part of the ERCOT grid and offers retail-rate net metering. Combined with 6.0+ peak sun hours, El Paso is one of the stronger solar markets in the state.
Does Solar Make Financial Sense in Texas Without the Federal Credit?
Honestly, the math is tighter in Texas than most solar marketing materials suggest — especially in the deregulated ERCOT market with low rates and poor net metering terms.
Solar is a good fit in Texas if:
- You're in Austin Energy or El Paso Electric territory with better export terms
- You drive an EV and charge at home — displacing $0.13/kWh grid electricity with free solar has a clear ROI
- You plan to stay in the home 12+ years and value energy independence
- Your electricity usage is high (above 1,500 kWh/month) — more solar production means more self-consumption
Solar is harder to justify in Texas if:
- You're in an ERCOT territory with $0.04/kWh export rates and below-average electricity costs
- You have significant shading on your roof
- Your payback horizon is under 8 years
Use the Solar ROI Calculator to run your specific numbers — input your current electricity rate, annual usage, and your utility's export rate to get a realistic payback estimate. If you're considering pairing solar with an EV charger, the EV Charger Cost Calculator can help you plan the full system.
What's Not Included in a Texas Solar Quote
Texas installers sometimes offer unusually low per-watt prices — but watch for missing line items:
- Panel upgrades required for hurricane windspeed ratings — particularly in coastal areas (Corpus Christi, Houston, Galveston). IBC-rated racking can add $500–$1,500.
- Electrical panel upgrades — common in older Texas homes; adds $1,500–$3,500
- Interconnection fees — vary by utility; ERCOT utilities may charge $100–$500
- Monitoring system — some budget installers charge separately

Bottom Line
Texas solar costs are among the lowest in the nation, but the value proposition is more nuanced than in states with high electricity rates or strong export credits. For Austin and El Paso homeowners, the math is genuinely compelling. For most of the deregulated ERCOT market, payback periods of 12–16 years are realistic — not terrible over a 25-year panel lifespan, but not the slam-dunk you'll see in California or New York.
The property tax exemption is a real, underappreciated benefit — it adds substantial untaxed equity to your home. Combined with low install costs and strong sun, Texas solar can work. Run the numbers for your specific utility and usage with the Solar ROI Calculator before making a decision.
