Texas Solar in 2026: What Actually Changed

If you are researching solar in Texas right now, you need to understand one thing before anything else: the 30% federal solar tax credit is gone for systems you own. The One Big Beautiful Bill Act (OBBBA), signed July 4, 2025, repealed Section 25D for any system placed in service after December 31, 2025.

If a solar company tells you in 2026 that you can still claim the 30% federal credit on a system you own, that is incorrect or worse — a deliberately misleading sales tactic. The IRS confirmed in their official OBBBA FAQ published in 2025 that installation completion date controls eligibility. A deposit in 2025 does not save the credit if the system was not operational by December 31, 2025.

This changes the math for Texas homeowners. The good news is, Texas was never built around the federal credit the way states like California were. The Lone Star State has its own structural advantages — property tax exemption, high solar irradiance, deregulated electricity market — that keep solar economically viable, even without the 30% sweetener.

Average Solar System Cost in Texas (2026)

A typical 7-10 kW residential solar system in Texas costs:

  • Before any incentives: $23,000 to $30,000
  • After local utility rebate (if applicable): $20,500 to $27,500
  • TPO lease alternative: $0 down, with monthly payments below your current electric bill in most cases

Most Texas installers price between $2.17 and $3.00 per watt installed. Battery storage adds $10,000 to $18,000 depending on capacity. Adding a battery is often what unlocks the Oncor rebate (up to $9,000), which can offset most of the battery cost.

Texas Solar Incentives Still Available in 2026

Texas has no state income tax, so there is no state-level solar credit. What remains is structured into three categories:

1. Property Tax Exemption (Statewide)

Under Texas Tax Code Section 11.27, the added home value from a solar energy system is 100% exempt from property tax assessment. You file Form 50-123 with your county appraisal district. Given Texas has one of the highest property tax rates in the country (~1.6% average), this exemption alone is worth roughly $400-600 per year in avoided tax over the system’s lifetime.

2. Local Utility Rebates

These vary widely by service territory:

  • Austin Energy: $2,500 rebate for systems 3kW+ after completing a free solar education course
  • CPS Energy (San Antonio): Program funding status changes — check current availability
  • Oncor (DFW area): Up to $9,000, but ONLY for systems with battery storage
  • AEP Texas: SMART Source Solar PV Program, performance-based, variable
  • New Braunfels Utilities: Up to $3,000 for systems 3kW+

3. Solar Buyback Plans (REP-dependent)

Texas does not mandate net metering, but several retail electric providers offer buyback plans. Buyback rate is one of the largest variables in your long-term return. Compare these before signing up for solar:

  • Green Mountain Energy Renewable Rewards Buyback
  • Reliant Simple Solar Sell Back
  • TXU Energy Home Solar Buyback Plan
  • Chariot Energy
  • Rhythm Energy

A buyback rate of 8¢/kWh vs 3¢/kWh on a typical system can mean $400-700/year difference in savings.

4. Third-Party-Owned Leases (Federal credit still flows through)

If you lease or sign a Power Purchase Agreement (PPA), the leasing company claims the Section 48E commercial credit (30%), as long as the project begins construction before July 4, 2026. This typically results in lease pricing that is roughly 20-30% lower than what you would otherwise see. The trade-off: you do not own the system, you do not capture future utility savings the same way, and you cannot claim the Texas property tax exemption (because you do not own the equipment).

Is Solar Worth It in Texas Without the Federal Credit?

The honest answer: it depends on three things.

  1. Your monthly electric bill. Above $200/month, solar still pencils out reasonably in most Texas markets. Below $100/month, the math gets harder.
  2. Your utility and REP. Customers in Austin Energy or Oncor territory have more rebate options than those in rural CenterPoint or AEP territory. A good solar buyback plan can shorten payback by 2-3 years.
  3. Whether you can add battery storage. Batteries add cost but unlock the Oncor rebate and dramatically improve resilience during Texas grid emergencies. After 2021 winter storm Uri, battery attachment in Texas rose to 35%+ of new installs.

Typical payback periods in Texas in 2026:

  • With battery + Oncor rebate + good buyback plan: 8-10 years
  • Solar-only + Austin Energy rebate + buyback plan: 9-11 years
  • Solar-only + no local rebate + average buyback: 11-13 years

System lifetime is 25-30 years, so even at the longer payback end, lifetime savings are typically $20,000-$40,000.

Top Cities for Solar in Texas

  • Austin — best rebate program through Austin Energy, strong irradiance, mature installer market
  • San Antonio — CPS Energy programs (check current funding), large installer base
  • Houston — high cooling costs make solar especially valuable, CenterPoint territory limits rebate options
  • Dallas–Fort Worth — Oncor battery rebate is the largest in Texas, competitive installer pricing
  • El Paso — highest solar irradiance in the state
  • Corpus Christi / Rio Grande Valley — AEP Texas SMART Source program available

What to Look for in a Texas Solar Installer

Texas has thousands of solar installers and the quality range is wide. A bad installer can cost you more than the missing federal credit. Look for:

  1. Active Texas license and insurance. Verify through the Texas Department of Licensing and Regulation.
  2. NABCEP certification. The industry standard for installer competency.
  3. At least 5 years in business in Texas, not just nationally.
  4. Strong independent reviews on Google, BBB, and SolarReviews.
  5. 25-year panel warranty and 10+ year inverter warranty, with a clearly defined workmanship warranty.
  6. Local service area. They should be physically based in your region, not 200 miles away.
  7. No high-pressure sales. If they push for a same-day signature or won’t let you compare quotes, walk away.
