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.

Incentives & Rebates
Federal Residential Credit Caveat
The Section 25D expiration (residential solar ITC ended Dec 31, 2025) can reduce a $21,000 Texas solar project by about $6,300 if the homeowner qualifies.
Property Tax Exemption and Local Utility Programs
Texas excludes the added value of qualifying solar systems from property tax. Austin Energy, CPS Energy, and some co-ops may offer rebates or value-of-solar programs, but there is no statewide cash rebate.
Net Metering
Texas export credit rules depend on the retail electric provider, municipal utility, or co-op. Some REPs offer solar buyback plans, some cap credits, and some compensate exports near wholesale value. Verify import rate, export rate, monthly caps, and credit expiration.

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
Data Sources
Electricity rates
EIA Electric Power Monthly
Texas residential electricity benchmark used for avoided-cost savings.
Solar production
NREL PVWatts
Production assumptions for high-sun Texas metros such as Dallas, Austin, San Antonio, and Houston.
Federal incentive
IRS Residential Clean Energy Credit
Supports 2026 Section 25D expiration (residential ITC no longer available by default).
State and utility policy
DSIRE, Public Utility Commission of Texas, Austin Energy, CPS Energy
Supports property tax exemption, local rebate, and buyback-plan caveats.
Result Summary
Net cost before federal credit
$19,600-$23,200
Estimated for an 8 kW system at $2.45-$2.90/W before any federal residential credit.
Annual bill offset
$1,300-$2,600
Range reflects daytime air-conditioning load and REP export-credit differences.
Policy risk
Utility-specific
Changing retail plans can change solar economics even if the panels produce as expected.
