Texas Solar Guide 2026
Everything Texas homeowners need to know: costs, incentives, net metering policy, and what makes this state unique for solar.
Quick answer
Texas solar economics depend mainly on 5.5 average peak sun hours, an estimated $2.6/W installed cost, 13.0¢/kWh electricity, and the state's current net-metering rules.

Key fact about Texas solar
Texas leads the US in new solar installations in 2024–2025. The deregulated ERCOT grid means electricity rates vary — shop your energy plan to maximize solar value.

Texas Net Metering Policy
No statewide net metering law
Texas has no statewide net metering mandate. Some utilities (Austin Energy, CPS Energy) offer buyback programs. Most large utilities offer minimal export value — self-consumption maximization is key.
Texas Solar Incentives
Available in addition to any utility rebates. Federal 25D credit is $0 for homeowner-owned systems from 2026.
- ✓Property tax exemption on added home value from solar
- ✓Various municipal utility rebates (Austin Energy: $2,500)

State-specific decision guide
What to verify before signing a Texas solar quote
In Texas, the financial result depends on more than sunshine or the headline installation price. Confirm the export rule, program eligibility date, and interconnection timeline for your exact utility before treating a payback estimate as a promise.
Export value
This page models no statewide net metering law. Ask which tariff and export credit apply to your account, not only which program name appears in the proposal.
Incentive eligibility
Check equipment, income, installer, application, and placed-in-service rules before subtracting an incentive from the quote. Programs can close or change terms.
Interconnection
Budget for the published 2–8 weeks depending on utility and confirm who pays for a required meter, service upgrade, or engineering review.
Source trail: production assumptions use NREL PVWatts; incentive discovery should be checked against DSIRE; electricity-market context is available from the EIA. Confirm final tax treatment with the IRS and your utility.
