Solar Panels in Austin, TX: 2026 Cost, Austin Energy Net Metering & Savings

Austin and the bill

Austin Energy is the municipal utility. Customers do not shop retail providers the way Houston does. Austin Energy's solar tariff is the document that matters, and it is not Oncor's and not CPS Energy's. Austin is the cleanest Texas example of why 'ERCOT' is not a utility. You buy from the city. The value of exports is whatever Austin Energy's current tariff says. The resource is solid. Hail and a fast-growing set of new roofs west and north of the city are the construction issues. Infill houses in older central neighborhoods have shade and small planes. A tariff change at the city utility will move the savings more than a tenth of a sun hour will. The 2025 EIA residential average for Texas was 15.40 cents per kWh. That statewide figure is what our calculator uses. It is not the Austin Energy tariff. A rounded solar resource for this metro is about 5.1 peak sun hours a day.

Export credits and any SREC or REC

Austin is on a municipal utility, Austin Energy, not on a competitive retail plan. Austin Energy and CPS Energy publish their own solar tariffs. Most of the rest of ERCOT separates delivery (Oncor, CenterPoint, or AEP Texas) from a retail electric provider, and any buyback lives in the retail contract, which can expire. Do not use a Houston retail-plan screenshot on an Austin or San Antonio bill. This page does not quote the municipal credit.

Roofs, climate, permits, and HOAs

Expect a mix of 1950s bungalows, 1980s subdivisions, and new three-story infill with small roofs. The infill roofs are the ones that disappoint people who sized a system from the bill alone. If the roof cannot hold the kilowatts, the bill offset in our estimate is a ceiling you may not reach. A Austin permit comes from the local building department, not from Austin Energy. An HOA can add its own review. This page does not quote a TX permit fee or an approval, because both depend on the address. Read Austin Energy's current solar tariff before you compare bids. Ask the installer to use that tariff in the savings chart. Hail history on the roof belongs in the contract conversation, including who pays to remove the array for a future replacement.

Estimated cost range

Estimated cost range for Austin, labeled as an estimate and not a local quote: Berkeley Lab's August 2026 update put 2025 host-owned residential systems at about $3.60 per watt before incentives, about $3.00 per watt in the cash subset, and about $4.50 per watt in the loan subset. The median size in that set was 7.7 kW. Austin is about 5.1 peak sun hours a day, against about 5.3 statewide. The federal residential credit under 26 U.S.C. § 25D ended for systems placed in service after December 31, 2025. The IRS treats that expenditure as made when the original installation is completed.
