How Much Do Solar Panels Cost in Texas in 2026? (TDU Audit Edition)

Texas is one of the few states where solar pricing has held flat — sometimes even dipped — through 2026. Labor is cheaper, permitting is faster, and competition is fierce. But the installer-quoted "savings" numbers almost universally ignore the part of your bill that solar actually does not touch.

The 2026 Texas number: $2.20–$2.80 per watt installed

A 10 kW system in Texas runs $22,000–$28,000 turnkey before incentives. With a 13.5 kWh battery (essential post-Uri — see below), you are at $34,000–$43,000.

This is among the lowest pricing in the country. Texas has more residential solar installers per capita than any state except California, and they fight on price.

The TDU audit: where your real savings are hiding

Look at your CenterPoint or Oncor electricity bill. Three line items add up to your total:

• Energy charges — what your retail electric provider charges per kWh consumed. Solar offsets this.
• TDU delivery charges — what CenterPoint/Oncor charges to deliver electricity to your meter. Solar offsets almost none of this.
• Base/admin fees — fixed monthly charges. Solar does not touch these.

TDU charges in Texas typically run $0.04–$0.06 per kWh consumed, plus $5–$15/month base. For an average household, that is $400–$800/year that solar will NOT eliminate. Many installer proposals quote bill-elimination math that ignores this.

Before you sign any Texas solar contract, demand the installer show you the bill assuming your solar covers 100% of consumption — including the TDU charges that remain. That is the real payback math.

25D's death changes the Texas equation

The 30% federal credit (25D) terminated December 31, 2025. Cash and loan buyers in Texas in 2026 get zero federal credit. The pass-through 48E credit still exists for TPO/PPA — installer must begin construction by July 4, 2026 and certify FEOC compliance.

The local incentive picture in Texas is also thin. Austin Energy has a rebate (~$2,500). CPS Energy in San Antonio has a smaller one. Outside the municipal utilities, there is no state-level Texas solar incentive in 2026.

ERCOT and the case for battery in Texas

February 2021's Uri freeze killed 246+ Texans and proved ERCOT cannot be trusted in extreme weather. A 13.5 kWh battery on an average Texas home will keep a fridge, well pump, internet, and a couple of LED lights running for 24–48 hours during an outage. That is the difference between safety and a hospital visit.

Post-Uri, Texas insurance commissioners began factoring resilience into homeowner policy pricing. Some insurers offer 1–3% premium reductions for documented backup power. Get that documentation written into your install contract.

Honest broker take: Texas pricing is fair, but the TDU charge dodge is the biggest unspoken trick in the state. Audit your bill before signing anything. Free contract review at reviewingsolar.com.
