How much do solar panels cost in Texas in 2026?

Texas homeowners typically see $2.45-$2.90 per watt installed before incentives. An 8 kW system runs roughly $19,600-$23,200. The federal residential credit (Section 25D) expired Dec 31, 2025 and is not available by default for 2026 projects. Batteries, trenching, or main-panel upgrades will increase the final number.

Does Texas have net metering?

Texas has no statewide net metering mandate. In deregulated ERCOT areas, your retail electric provider decides whether and at what rate exported solar is credited. Some REPs offer near-retail buyback, others pay wholesale or cap monthly credits. Austin Energy and CPS Energy use their own solar credit structures, while co-ops and municipal utilities each set separate rules.

Which utilities serve Texas for solar?

Oncor Electric delivers power across much of North and West Texas, CenterPoint Energy covers the Houston area, and Texas-New Mexico Power serves parts of West Texas and the Gulf Coast. These are transmission and distribution utilities — in deregulated areas, your retail provider (REP) is a separate company you choose. Municipal utilities like Austin Energy and CPS Energy in San Antonio serve their own territories directly.

What incentives are available for Texas solar?

The federal residential credit (Section 25D) expired Dec 31, 2025. Texas offers a property tax exemption that prevents the added value of solar from increasing your property tax bill. Austin Energy, CPS Energy, and some co-ops offer local rebates or value-of-solar programs, but there is no statewide cash incentive. Check your specific utility before budgeting.

Is solar worth it in Texas if electricity rates are moderate?

It can be, but it depends heavily on your retail plan. Strong Texas sun means good production, but ROI hinges on whether that output offsets your retail import rate or is exported at a lower buyback rate. Homes with heavy summer daytime air-conditioning load tend to see the best economics because they consume solar directly.

What should I check before signing a Texas solar contract?

Confirm the REP's solar buyback rate, whether credits roll over or expire monthly, the import rate after any promotional period ends, and whether the installer sized your system around your actual interval usage data. In Texas, your electricity plan choice matters as much as your panel production — switch plans and your solar economics change with it.

Solar Panel Cost in Texas (2026)

Estimate Texas solar economics across deregulated REP plans, municipal utilities, and high-sun roof conditions.

Last updated: 2026-06-09· Source label: EIA residential electricity rates, IRS federal clean energy credit, NREL/PVWatts solar assumptions

Texas solar sits in its own world: the ERCOT grid is an electric island disconnected from the rest of the country, and the retail electricity market is deregulated — meaning you shop for a provider, not just a utility. Residential rates average around $0.16/kWh, and natural gas runs about $2.46/therm, both near national norms. But there is no statewide net metering mandate. Your solar export value depends entirely on which retail electric provider (REP) you choose and what buyback plan they offer. Some REPs credit exports near wholesale value, others near retail, and some cap credits monthly. The major transmission utilities — Oncor, CenterPoint, and Texas-New Mexico Power — deliver the power, but they don't set your solar terms. Municipal utilities like CPS Energy in San Antonio and Austin Energy offer their own rebate or value-of-solar programs. Strong Texas sun helps production, but the financial result lives or dies on the electricity plan you pick.

Calculation Method

Texas solar payback = net system cost before eligible federal credit and rebates / annual avoided electricity cost plus export credits

Key Assumptions

Policy last reviewed: 2026-06-09. Federal residential credit assumptions are project-year dependent and not applied by default for 2026+ projects.
Texas residential electricity rate around $0.14-$0.17/kWh depending on REP and utility territory
8 kW reference system before incentives
Section 25D expired Dec 31, 2025 (residential ITC no longer available by default) applied to eligible installed cost
Export-credit value depends on retail electric provider buyback plan
