Texas is emerging as one of the most important solar markets in the United States — and the numbers justify the momentum. The state averages 5.2 to 6.5 peak sun hours per day depending on location, with El Paso recording some of the highest solar irradiance of any major US city. Summer electricity bills in Texas homes regularly spike to $280 to $400 per month driven by air conditioning loads — making the financial case for solar compelling when those bills are what solar is measured against.
Texas also has no state income tax, which means there are no state solar tax credits — but it also means no state tax complexity, and the federal 30% ITC is the primary and sufficient incentive. Texas law mandates property tax exemptions for solar equipment, and the competitive ERCOT electricity market means choosing the right retail electricity provider can meaningfully impact your solar economics.
This guide gives Texas homeowners the accurate, complete picture of solar in 2026 — from Dallas and Houston to El Paso and San Antonio — with real cost data, savings by city, ERCOT’s impact on net metering, and an honest assessment of whether solar makes financial sense for your specific home.
Texas Solar 2026 — The Bottom Line:
| Texas solar is financially worthwhile for most homeowners with a monthly electricity bill above $130. An 8kW system costs $15,120 to $17,360 net after the 30% ITC, saves $1,600 to $2,200 per year, and pays back in 7 to 9 years. Property and sales tax exemptions add long-term value. El Paso leads the state with 6.5 sun hours per day; the Austin area follows with excellent solar generation potential. |

How Much Do Solar Panels Cost in Texas in 2026?
Texas has a mature, competitive solar installer market — particularly in the Dallas-Fort Worth metroplex, Houston, San Antonio, and Austin. In 2026, residential solar costs $2.70 to $3.10 per watt installed. An 8kW system costs $21,600 to $24,800 gross before the 30% federal ITC brings the net cost to $15,120 to $17,360.
| System | Gross Cost | After 30% ITC | Monthly Saving | Annual Saving | Payback |
| 5 kW | $13,500–$15,500 | $9,450–$10,850 | $100–$130/mo | $1,200–$1,560 | 9–11 yrs |
| 6 kW | $16,200–$18,600 | $11,340–$13,020 | $120–$155/mo | $1,440–$1,860 | 8–10 yrs |
| 8 kW | $21,600–$24,800 | $15,120–$17,360 | $155–$200/mo | $1,860–$2,400 | 7–9 yrs |
| 10 kW | $27,000–$31,000 | $18,900–$21,700 | $190–$245/mo | $2,280–$2,940 | 8–10 yrs |
| 12 kW | $32,400–$37,200 | $22,680–$26,040 | $225–$290/mo | $2,700–$3,480 | 9–11 yrs |

Solar Savings by Texas City — Where the Sun Delivers Most
| City | Avg. Rate | Peak Sun Hrs | Monthly Saving (8kW) | Annual Saving | Payback |
| El Paso | 12¢/kWh | 6.5 hrs | $145–$185/mo | $1,740–$2,220 | 7–8 yrs |
| Lubbock | 11¢/kWh | 6.2 hrs | $135–$170/mo | $1,620–$2,040 | 7–9 yrs |
| Dallas-Fort Worth | 13¢/kWh | 5.5 hrs | $145–$185/mo | $1,740–$2,220 | 7–9 yrs |
| San Antonio (CPS) | 12¢/kWh | 5.5 hrs | $130–$165/mo | $1,560–$1,980 | 8–9 yrs |
| Houston | 13¢/kWh | 5.3 hrs | $140–$180/mo | $1,680–$2,160 | 8–9 yrs |
| Austin (Austin Energy) | 10¢/kWh | 5.5 hrs | $110–$140/mo | $1,320–$1,680 | 9–11 yrs |
El Paso’s exceptional solar resource — 6.5 peak sun hours, the highest of any major Texas city — produces strong generation even with a moderate electricity rate. The panhandle and West Texas regions are particularly strong solar markets. Austin Energy customers see lower savings due to the utility’s below-average electricity rate, though Austin still achieves positive ROI on any reasonable time horizon.
ERCOT and Texas Net Metering — What You Must Know
Texas’s unique ERCOT grid — which covers approximately 90% of the state and operates independently of the eastern and western US interconnections — has an important consequence for solar homeowners: there is no state-mandated net metering policy. What you receive for surplus solar generation depends entirely on your specific retail electricity provider.
In the competitive ERCOT retail market, most providers offer some form of buyback or credit for solar exports, but rates and terms vary significantly:
- AEP Texas and Oncor distribution territories: several retail providers offer solar buyback programmes. Compare providers specifically for solar terms before switching — the difference between providers can be 3 to 8¢/kWh on exports.
- CPS Energy (San Antonio, municipal): offers the Save for Tomorrow Energy Plan (STEP) with solar export compensation. Check current rates at cpsenergy.com.
- Austin Energy (Austin, municipal): Green Choice programme and net metering with credit at retail rate for systems installed before certain thresholds. Verify current terms directly.
- New providers entering the ERCOT market regularly update solar terms — always request solar-specific rate plan information when comparing providers.
The practical takeaway: research your retail electricity provider’s solar export terms before installation. For homeowners who primarily self-consume (60%+ of generation used in home), the export rate matters less — but for larger systems that generate significant surplus, provider selection can add $100 to $400 per year to your effective savings.
Texas Solar Incentives in 2026
Texas homeowners qualify for the federal 30% ITC — the most powerful residential solar incentive in the US. Texas also provides meaningful automatic incentives:
- Property Tax Exemption: Texas Property Tax Code Section 11.27 exempts solar and wind energy devices from local property tax assessment. A system that adds $18,000 to your home’s value saves $360 to $900 per year in property tax at typical Texas rates (2 to 5% millage).
- Sales Tax Exemption: Solar devices used to produce electricity in Texas are exempt from state sales tax, saving approximately $1,700 to $2,200 on a typical 8kW installation.
- No State Income Tax: Texas has no state income tax — no state tax credit, but also no state return complexity and a simpler ITC claim process.
- Some municipal utility rebates: Austin Energy and CPS Energy periodically offer additional rebates or incentive programmes. Check directly with your utility for current offerings.

Is Solar Worth It in Texas in 2026?
For most Texas homeowners with a monthly electricity bill above $130 and a home tenure of 10+ years, solar delivers a solid financial return in 2026. The key factors: excellent sun hours across most of the state, the 30% federal ITC, property and sales tax exemptions, and electricity bills that spike significantly in summer due to air conditioning.
The main caveat is your electricity rate. In ERCOT’s competitive retail market, rates range from under 9¢/kWh on some promotional plans to 15¢/kWh+ on standard fixed-rate plans. At below 9¢/kWh, solar payback extends to 12 to 15 years. At 13 to 15¢/kWh standard market rates, payback of 7 to 9 years is achievable. Always calculate payback based on your actual current rate, not promotional rates that may expire.
Frequently Asked Questions — Texas Solar 2026
Does Texas have state solar incentives beyond the federal ITC?
Texas has no state income tax credit for solar in 2026. However, the property tax exemption and sales tax exemption are automatic and meaningful — worth $2,500 to $4,500 in combined benefit over a typical system’s life. Some municipal utilities (Austin Energy, CPS Energy) offer additional utility rebates or favourable solar rate programmes. Always check directly with your utility before installation.
Can Texas solar panels power my home during a grid outage?
Standard grid-tied solar systems shut off automatically during grid outages for safety — this is a regulatory requirement. To have power during an outage (including ERCOT weather-related failures), you need battery storage or a hybrid inverter system with islanding capability. Given ERCOT’s history of extreme weather disruptions, battery backup is a particularly relevant consideration for Texas homeowners. The 30% ITC applies to battery storage, reducing a $12,000 Powerwall to $8,400 net.
Is solar worth it in Texas despite moderate electricity rates?
Yes — for most Texas homeowners. While Texas average rates of 11 to 13¢/kWh are moderate compared to California or Massachusetts, Texas households consume significantly more electricity due to heavy summer air conditioning. A 2,500 sq ft Texas home often uses 1,400 to 1,800 kWh in July. This high seasonal consumption makes solar particularly valuable. Annual savings of $1,700 to $2,200 with a 7 to 9 year payback is achievable for most Texas homeowners.
What size solar system does a Texas home need?
The average Texas home consumes 1,100 to 1,400 kWh per month annually — significantly above the US average due to air conditioning. A 3-bedroom Texas home typically needs 8 to 12kW to achieve 90%+ coverage. Homes with pools, multiple AC units, or an EV charger should size for 12 to 16kW.
