Is solar worth it in Austin in 2026?
A roof in Austin produces about 1,499 kWh a year per kW of panels. For a home with a $150 monthly bill, a 7.5 kW system costs about $29,908 at Texas's median price and pays for itself in roughly 28.6 years, with no federal tax credit. That is 4% more sun than Houston, the city on our Texas page.

How Austin homes get paid for solar
Export rules are set at the state and utility level, not by the city. Austin is under Texas's rules set by each utility: Texas has no statewide net metering rule for homes; export pay is set by your retail electric provider's buyback plan or by your city utility (Austin Energy, CPS Energy). The full rules, incentives and sources are on theTexas page.
Austin: your utility, incentives and permits
Main utility: Austin Energy (city-owned). Checked 2026-10-27 against the sources below.
Austin Energy, a department of the City of Austin, is the city’s own electric utility. Its service area includes the City of Austin and all or portions of Bee Cave, Lakeway, Rollingwood, Westlake Hills, Sunset Valley, Pflugerville, Cedar Park and other nearby communities. About half of that area lies inside the city limits, so check your bill to confirm your utility.
What Austin Energy pays for solar
Austin Energy pays through a Value of Solar rate: it meters your solar production and credits 100% of that production at the Value of Solar rate. For systems under 1 MW-AC the rate is 12.89 cents per kWh, effective October 1, 2026 and subject to change. The rate is updated every three years.
Because you are credited for everything the panels produce, not only the exports, you are still charged for all the energy your home consumes, whether it comes from your panels or the grid. The credit then reduces your electric charges. Excess credit carries over month to month, cannot be cashed out, and does not apply to water, trash or other services. Austin Energy recommends sizing the system to your annual energy use.
Incentives in 2026
- Austin Energy rebate. The utility offers a $4,000 rebate for eligible home solar projects. The system must be 3 kW (DC) or larger and mostly free of shading, installed by an Austin Energy participating contractor, and you must receive a Solar Rebate Confirmation Letter before installation.
- Property tax exemption. Texas lets owners claim an exemption on the added appraised value of a solar device used mainly for on-site energy, using Form 50-123 filed with the county appraisal district between January 1 and April 30 of the year you want it.
- No federal credit. The 30% credit is not available for property placed in service after December 31, 2025; see what ended with the federal credit.
Permits and connection
Every solar system in Austin Energy territory needs an Auxiliary Power electrical permit from Austin Development Services. Applications go through the Austin Build + Connect portal, and the contractor must be registered as a City of Austin vendor. Residential ground-mounted or solar shingle systems also need a residential plan review and a building permit. After approval, the permit’s fees are billed automatically and the contractor pays them. The manual does not list the fee amounts.
Residential interconnection requires an Interconnection Agreement form, whether or not you take the rebate. After the contractor schedules the final inspection and the system passes, Austin Energy installs the solar meter and you have Permission to Operate. The wider Texas rules are on the state page.

Why the city matters
Two things change from one city to another in the same state: the sun, which sets how many panels you need, and the utility, which sets what exported power is worth. Austin gets 1,499 kWh per kW a year on a south-facing roof at a 20° tilt, so covering a year of use for a $150 bill at 16.1¢ takes about 7.5 kW, roughly 19 panels of 400 W. Electricity prices in the calculator are the Texas residential average; your utility's rate can be higher or lower, so put your own bill in.
