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 Lubbock array would produce, with rates rising at 2.5% a year, comes to roughly $65,685.
If a battery is part of the plan, the battery buy vs. TPO calculator prices owning one against a lease or TPO deal.
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 (this page) | 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 | 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, Lubbock runs 16% above Texas’s 1,455 kWh per kW — a payback 1.4 years shorter than the statewide 10.7-year estimate on the same hardware at the same price.
What sets Lubbock apart
High plains, thin air and low humidity put Lubbock second only to El Paso in Texas — nearly 300 kWh/kW ahead of Houston.
No single utility rate: Lubbock is deregulated
Lubbock sits in ERCOT’s retail-choice market, so there is no one utility whose price we can quote the way we do for regulated cities. Lubbock Power & Light (moved its customers to ERCOT retail choice in 2024) owns and maintains the wires and charges a delivery fee that appears on every bill, but the energy itself — the cents per kWh you actually pay, and whether your solar exports earn anything — is set by the Retail Electric Provider (REP) contract you choose. Texas has no statewide solar-export mandate: buyback exists only as specific REP plans, and terms differ even between plans from the same provider.
Practical consequences for the numbers on this page: the payback above uses the Texas average residential rate, because that is the only honest single figure available. Before trusting any payback estimate, rerun the calculator with the rate from your own REP contract, and if you are going solar, compare REP buyback plans on two numbers — what they charge you per imported kWh and what they credit per exported kWh — not on the headline rate alone. Solar sales in these metros also lean heavily on third-party ownership — a lease or PPA layered on top of the REP choice — so be clear which of the two contracts you are actually signing.
Lubbock has the best solar resource of any deregulated Texas city we track. High-plains elevation, thin air, and low humidity push its PVGIS-modeled yield to 1,682 kWh per kW per year — second in Texas only to El Paso’s 1,784, about 6% back of that desert benchmark, roughly 16% above Dallas (1,455) and nearly 300 kWh/kW ahead of Houston (1,389). At the 16.44¢/kWh statewide average residential rate our headline model uses, each installed kW’s output is worth on the order of $275 a year if fully credited — the strongest gross production case on any of our deregulated Texas pages.
The market side is the newer story. Lubbock Power & Light, the city’s municipal utility, moved its customers into ERCOT retail choice in 2024, making this the youngest retail-choice market in Texas. LP&L still owns and operates the wires; the electricity itself is now sold by competing retail providers, exactly as in Dallas or Houston. The instructive contrast is El Paso: the other high-yield West Texas city, kept a regulated utility with a published 13.46¢/kWh average rate, while Lubbock traded that certainty for a menu of contracts. Similar sun, opposite market structures — and this page can print a real electricity price for El Paso but not for Lubbock.
Being new to retail choice cuts one specific way for solar buyers: there are only a few years of local history with buyback plans here, fewer neighbors who have lived through a full contract cycle, and less accumulated word-of-mouth about how specific plans actually settle out. So read contracts, not marketing. Our export-rules data classifies Texas as utility-dependent — no statewide mandate, buyback only through voluntary REP plans, and terms that differ even between plans from the same provider — and models a conservative 3.0¢/kWh export value. Against a 16.44¢ average rate, that is a five-to-one gap between offsetting a kilowatt-hour and selling one at the floor. Price any plan on both sides of the meter — import rate, export credit, monthly fees — using Lubbock’s roughly 1,682 kWh of annual production per kW, and expect to re-shop when the contract term ends.
Costs favor you on paper: Texas quotes average $2.25 per watt in EnergySage’s August 2026 data, though LBNL’s realized installed prices for the state run $4.04/W across 2,670 systems — an 1.8x spread that makes multiple bids essential. And for 2026, the federal residential credit is $0 on a cash or loan purchase; 30% survives only through a lease or PPA claiming the §48E credit, on the leasing company’s terms.
Lubbock 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 Lubbock for exported power
Texas has no statewide export-credit requirement, and Lubbock 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 18.6 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 1,682 kWh per kW figure for Lubbock 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 Lubbock 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 Lubbock 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 Lubbock?
Roughly 9.3 years on this model, using Lubbock’s own production figure of 1,682 kWh per kW and Texas’s 15.9¢/kWh average rate and its set by your utility or retail provider export rule. That includes $150 a year of running costs and one inverter replacement, which many published paybacks leave out.
Is Lubbock better or worse for solar than the rest of Texas?
Against the state figure, Lubbock runs 16% above Texas’s 1,455 kWh per kW — a payback 1.4 years shorter than the statewide 10.7-year estimate on the same hardware at the same price.
Is solar worth it in Lubbock in 2026?
At 15.88¢/kWh and 1,682 kWh per kW, an 8 kW system in Lubbock pays back in about 9.3 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.
