Only the first two rows differ. Everything financial — rate, tariff, price per watt — is inherited from Texas without change, which is the point: a city page that quietly used a different electricity rate from its state page would be guessing, not measuring.
Doing nothing is not free either. Twenty-five years of the electricity an 8 kW Austin array would produce, with rates rising at 2.5% a year, comes to roughly $56,497.

Run it with your own bill
Shared methodology · identical on every city page
- Production figures are unshaded, south-facing, 20° PVGIS values. A real roof — its own pitch, orientation, a tree or a chimney — typically produces 10–25% less; every payback here already carries a 10% real-roof derate.
- Paybacks include $150/yr of running costs and one $2,000 inverter replacement in year 14, which is why they run longer than paybacks quoted elsewhere.
- State export rules cover investor-owned, state-regulated utilities. Municipal utilities and rural electric cooperatives are exempt in most states and set their own terms.
- Installed cost is the state-level EnergySage market figure, not a city quote; a swing of 50¢/W moves payback by roughly a year and a half either way. Get three quotes before trusting any payback — including ours.
Texas is not one solar market
Across the 7 Texas cities with their own modeled figures, production spans 28% — Houston at 1,389 kWh per kW to El Paso at 1,784. Every column except production is identical down this table: same 15.9¢/kWh retail rate, same export regime, same $2.25/W installed cost. The payback differences are caused by weather and nothing else.
| Location | kWh per kW per year | 8 kW output | Annual value | Payback |
|---|---|---|---|---|
| El Paso | 1,784 | 12,845 kWh | $2,040 | 8.8 yrs |
| Lubbock | 1,682 | 12,110 kWh | $1,923 | 9.3 yrs |
| Corpus Christi | 1,479 | 10,649 kWh | $1,691 | 10.5 yrs |
| San Antonio | 1,457 | 10,490 kWh | $1,666 | 10.7 yrs |
| Dallas | 1,455 | 10,476 kWh | $1,664 | 10.7 yrs |
| Austin (this page) | 1,447 | 10,418 kWh | $1,654 | 10.7 yrs |
| Houston | 1,389 | 10,001 kWh | $1,588 | 11.2 yrs |
| Texas state average | 1,455 | 10,476 kWh | $1,664 | 10.7 yrs |
Against the state figure, Austin runs 0.5% below Texas’s 1,455 kWh per kW — a payback 7.1 years longer than the statewide 10.7-year estimate on the same hardware at the same price.
What sets Austin apart
Effectively identical to San Antonio and Dallas — central Texas is a flat plateau for solar, with the real variation lying west.
Your utility, officially
Texas’s average residential rate is 15.9¢/kWh, but the bill in Austin comes from Austin Energy at 12.58¢ — 21% below the state figure. These are the residential figures Austin’s utility reported to the U.S. Energy Information Administration on Form EIA-861 for 2024 — computed as revenue ÷ sales from the official file, not estimated:
| Utility | EIA ID | Residential avg price | Residential customers | Net-metering (residential, self-reported) |
|---|---|---|---|---|
| Austin Energy | 1015 | 12.58¢/kWh | 507,291 | not reported |
How exports are treated matters as much as the headline price: Austin Energy is modeled here under a flat per-kWh export credit on everything the array generates, and that treatment is baked into every payback figure on this page.
Austin does not work the way the rest of urban Texas does. Homes here are billed by Austin Energy, a municipally owned utility — a department of the City of Austin, its rates set by the City Council — serving 507,291 residential customers at a 2024 average of 12.58¢/kWh per the EIA-861 file. There are no retail electricity providers to shop, no REP buyback contracts to compare, and none of the deregulated-market caution this page applies to Dallas and Houston. Austin sits inside ERCOT but outside its retail-choice regime.
Now look at the utility table above: no net-metering figures. That is not a data gap. Austin Energy reports zero residential net metering to EIA because it does not net-meter at all. It has long used a different structure entirely, the Value-of-Solar (VoS) rate — widely credited as the first of its kind in the country — and the mechanics matter. Under VoS, Austin Energy meters your solar production separately and credits 100% of it — not just the surplus you export — at the VoS rate, while billing you at retail for 100% of your consumption, including the solar electricity you use in your own house. Per Austin Energy’s official VoS page (austinenergy.com ), the credit for systems under 1 MW-AC is 9.91 cents per kilowatt-hour, effective March 1, 2023 and explicitly subject to change; unused credit rolls forward month to month, is non-transferable, and offsets only the electric portion of the city utility bill.
The consequences cut both ways. Self-consumption buys you nothing extra here — running the dishwasher at noon is pointless arbitrage, because every solar kilowatt-hour earns 9.91¢ whether you use it or export it, and every consumed kilowatt-hour costs retail either way. That makes the economics simple and battery-hostile: there is no rate spread for a battery to harvest. It also makes the payback on this page, which assumes full-retail crediting, optimistic for Austin — the working credit sits roughly 2.7 cents under Austin Energy’s 12.58¢ average retail price, applied to your entire production. Austin Energy’s own advice is to size the system to your annual consumption, since the credit cannot leave the bill.
One last caution: the VoS rate is recalculated by the utility and has moved over time. Verify the current figure on the page linked above before modeling anything; the 9.91¢ printed here was checked against Austin Energy’s site in September 2026 and will not update itself.

Austin against the rest of Texas
Same rate, same export rule, same installed price per watt — only the sunshine changes:
| City | kWh per kW | Payback |
|---|---|---|
| El Paso | 1,784 | 8.8 years |
| Lubbock | 1,682 | 9.3 years |
| Corpus Christi | 1,479 | 10.5 years |
| San Antonio | 1,457 | 10.7 years |
| Dallas | 1,455 | 10.7 years |
| Austin | 1,447 | 10.7 years |
| Houston | 1,389 | 11.2 years |
A 28% production span across one state is the reason a single statewide number is only ever a starting point.
What Texas pays Austin for exported power
Texas has no statewide export-credit requirement, and Austin is no exception. What you are paid for surplus power is set by your utility or retail provider — REP solar buyback plans — not by state law.
The headline range runs from full-retail credit (the best case) to a reduced credit of 3.0¢/kWh with 40% of generation used on site — roughly 21.2 years against the full-retail figure — because the export rule is not verified with your utility. That single contract term outweighs the entire production gap between El Paso and Houston — get the buyback terms in writing.
No statewide mandate. Terms are set by your retail electricity provider and differ between plans from the same provider.
Sources and method
- Production: modeled with PVGIS v5.2 PVcalc (European Commission JRC) using the PVGIS-NSRDB radiation database — the same NREL satellite dataset PVWatts draws on for the Americas. Assumptions: 4 kWp, standard c-Si, 14% system loss, roof mounting, 20-degree tilt, due south, horizon shading on. The 1,447 kWh per kW figure for Austin is a modeled location point, not an interpolation from the Texas average. PVGIS is free to use with JRC attribution requested; the underlying NSRDB is public domain (NREL/DOE).
- Real-roof derate: a separate 10% deduction for azimuth, pitch and shading, applied in the shared model rather than folded into the production data — so you can adjust it if your roof is genuinely unobstructed.
- Electricity rate: U.S. Energy Information Administration, average price by state . This is Texas’s residential average; EIA does not publish a Austin figure, so the state rate is used and labeled as such.
- Export rules: REP solar buyback plans, from our Texas state page and the shared export-rules dataset behind it.
- State average rate: EIA Table 5.6.A, July 2026 data (released Sep 2026), used for every state-average comparison on this page.
- Payback model: shared with the solar savings calculator and the state pages — 2.5%/yr utility inflation, 0.5%/yr degradation, $150/yr running costs, one $2,000 inverter replacement in year 14, federal credit $0. The rest of the toolset — battery, sizing, financing — is under all calculators .
- Incentives: DSIRE . City and utility programs change more often than state ones — check yours directly.
Electricity rate, export regime, production figure and installed cost on this page were last verified on 30 August 2026. Export credits reset on annual tariff cycles and incentive budgets run out mid-year, so treat every figure as a snapshot at that date and confirm current terms before acting. Nothing here is tax or financial advice.
Frequently asked questions
How much do solar panels cost in Austin in 2026?
About $18,000 for a typical 8 kW system at $2.25 per watt, before any incentive. With the federal credit at $0 in 2026 that is close to your net cost. Note that the price per watt is a Texas market average — there is no reliable city-level cost data, so treat it as a starting point and get three quotes.
What is the solar payback in Austin?
Roughly 17.8 years on this model, using Austin’s own production figure of 1,447 kWh per kW and its own utility tariff (12.58¢/kWh) with each utility’s real export treatment. That includes $150 a year of running costs and one inverter replacement, which many published paybacks leave out.
Is Austin better or worse for solar than the rest of Texas?
Against the state figure, Austin runs 0.5% below Texas’s 1,455 kWh per kW — a payback 7.1 years longer than the statewide 10.7-year estimate on the same hardware at the same price.
Is solar worth it in Austin in 2026?
At 15.88¢/kWh and 1,447 kWh per kW, an 8 kW system in Austin pays back in about 10.7 years on this model. Treat that as a starting point for reading real quotes rather than as a quote: your roof’s orientation, its shading and the price you are actually offered will move it more than your city does.
How we calculated this
Year-1 saving = production (kW × the city’s modeled kWh per kW) × the blended kWh value (retail rate for self-use, the state export rule for exports). Payback = net cost ÷ year-1 saving, with the federal credit at $0 for 2026 purchases and cost per watt from the state’s installed-price band. Production is modeled from PVGIS/NSRDB irradiance for the city.Sources: U.S. Energy Information Administration (EIA) electricity rates · DSIRE incentive records · public IRS/OBBBA guidance.
