Net metering, tax credits and incentives in 2026
Texas pays less than retail for exported solar power. Under Retail provider solar buyback plans, power you send to the grid earns about 6.0¢/kWh, against 16.1¢ for power you buy. We assume 40% of a no-battery system's output is used at home as it's produced (worth the full price) and the rest is exported, so each solar kWh is worth about 10.0¢. Using more of your solar yourself, by running appliances midday or adding a battery, raises that.
Texas has no statewide net metering. In competitive areas the export credit depends on your retail plan: most buyback plans pay about 3-9¢, a few match retail. Austin Energy pays a 9.9¢ value-of-solar rate; CPS Energy about 3-4¢. Source.
There is no federal tax credit for buying home solar installed in 2026. The 30% Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025, so the costs and paybacks on this page include no federal credit.
Texas and local utilities may still offer rebates, performance payments, property-tax or sales-tax exemptions. Search the DSIRE incentives database for Texas and ask installers which programs they apply for you.
