Why this number
Las Vegas produces 1,689 kWh per kW, one of the highest figures in the country and slightly below Nevada’s 1,705 state band. Reno, 450 miles north, manages 1,596 — only 5.5% less. Both of them pay back slowly: 17.9 years here and 22.1 in Reno, because power is cheap — Nevada Power bills 15.33¢/kWh in Las Vegas — and exports are credited well below that.
An 8 kW system in Las Vegas, priced out

| Annual value of that output | ~$901 | ~$909 |
| Rough payback (your utility) | 17.9 years | 20.8 years (state-average model) |
| 25-year net position | $4,014 | — |
Only the first two rows differ. Everything financial — rate, tariff, price per watt — is inherited from Nevada 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 Las Vegas array would produce, with rates rising at 2.5% a year, comes to roughly $53,047.
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.
Las Vegas against the rest of Nevada
Two Nevada cities have their own modeled figures, and they are only 5.8% apart — Reno at 1,596 kWh per kW against Las Vegas at 1,689, which is a remarkably narrow gap by the standards of this dataset. The rate, the export rule and the $2.38/W installed cost are identical for both; only production moves.
| Location | kWh per kW per year | 8 kW output | Annual value | Payback |
|---|---|---|---|---|
| Las Vegas (this page) | 1,689 | 12,161 kWh | $901 | 21.0 yrs |
| Reno | 1,596 | 11,491 kWh | $851 | 22.1 yrs |
| Nevada state average | 1,705 | 12,276 kWh | $909 | 20.8 yrs |
Against the state figure, Las Vegas runs 0.9% below Nevada’s 1,705 kWh per kW — a payback 2.9 years shorter than the statewide 20.8-year estimate on the same hardware at the same price.
The Mojave delivers exactly what you would expect
Clear skies, minimal cloud, low humidity and a very high direct-beam fraction. There is little to say about Las Vegas irradiance except that it is excellent and stable — the year-to-year variation here is smaller than almost anywhere else in this dataset, which makes production modeling unusually reliable.
Summer heat is the one deduction. Rooftop cell temperatures in July regularly exceed 150°F, and the resulting derate is already inside the 1,689 figure. Mounting height and airflow under the array measurably affect this, and it is a fair question to ask an installer about.
Your utility, officially
Nevada’s average residential rate is 12.8¢/kWh, but the bill in Las Vegas comes from Nevada Power Co at 15.33¢ — 20% above the state figure. These are the residential figures Las Vegas’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) |
|---|---|---|---|---|
| Nevada Power Co | 13407 | 15.33¢/kWh | 916,385 | 117049 customers / 907.301 MW |
How exports are treated matters as much as the headline price: Nevada Power Co is modeled here under the state’s net billing rules, and that treatment is baked into every payback figure on this page.
One in eight. That is the residential solar penetration Nevada Power reported to EIA for 2024 — 117,049 net-metering homes out of 916,385 residential customers, backed by 907.301 MW of capacity — and it is the highest uptake of any utility in this site’s dataset outside California and Hawaii. Whatever you conclude about Las Vegas solar, start from the fact that a hundred thousand of your neighbors already ran the numbers and signed.
The company doing the billing is Nevada Power, the southern half of NV Energy. NV Energy operates Nevada as two separate investor-owned utilities with separate books: Nevada Power around Las Vegas at a 2024 EIA-861 average of 15.33¢/kWh, and Sierra Pacific Power around Reno at 14.52¢. Same parent, same regulator — the Public Utilities Commission of Nevada — but distinct rate cases and distinct prices, which is why this site carries Las Vegas and Reno as different markets rather than one Nevada number.
Exports here run under AB 405, the 2017 law that ended Nevada’s net-metering whiplash — the state briefly gutted net metering in 2016, watched the rooftop industry leave, and legislated it back. The design that emerged is a tiered excess-energy credit: exports earn a percentage of the retail rate rather than the full rate, with the percentage stepping down through capacity tiers as more solar interconnects statewide. Which tier is open now, and what your system locks in, is exactly the kind of moving detail we refuse to quote from memory — NV Energy’s site would not respond to our verification checks, so confirm the current tier and its terms on nvenergy.com before you model anything. Our Nevada page describes the regime’s mechanics.
On rate structure, NV Energy’s standard residential service is straightforward volumetric pricing with optional time-of-use plans alongside; which plan pairs best with solar depends on your cooling profile, and the current lineup is another thing to confirm on the utility’s own site. The load profile is the local angle worth naming: Las Vegas summer demand is a near-perfect solar client, with air conditioning running hardest exactly when panels produce most, so self-consumption — the part of the value that no tier reduction touches — does unusually heavy lifting here. The average reported system runs about 7.8 kW. In this town the utility data says solar is not a bet; it is the default.

Why the best sun in the country does not produce the best payback
This is the clearest case on the site of sunshine losing to price. A kilowatt of panels in Las Vegas produces about 3% more than one in Riverside, California — and earns about 55% less per year, because Nevada charges 12.8¢/kWh against California’s 34.7¢.
Nevada also uses net billing. Under AB 405 the excess-energy credit is tiered and steps down as statewide solar capacity grows, so exported power earns a fraction of retail. That combination — cheap power, discounted exports — is what puts payback around 17.9 years despite 1,689 kWh per kW. Self-consumption is the only lever with real leverage here: daytime cooling load, a battery, an EV charged in the afternoon.
What Nevada pays Las Vegas for exported power
Nevada does not credit exports at the retail rate, and that rule reaches Las Vegas unchanged. The program is AB 405 tiered excess energy credit , in force since 2017-06-15, crediting surplus power at an assumed 3.8¢/kWh, about 30% of retail, because no per-kWh figure is published against a retail rate of 12.8¢.
Because a typical home uses only about 40% of its generation as it is produced, most of what a Las Vegas array makes is sold at that lower rate. That is why the payback above is 17.9 years and not the 12.0 years the same hardware would return under full-retail net metering. Raising self-consumption is the lever that closes the gap.
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 1,689 kWh per kW figure for Las Vegas is a modeled location point, not an interpolation from the Nevada 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 Nevada’s residential average; EIA does not publish a Las Vegas figure, so the state rate is used and labeled as such.
- Export rules: AB 405 tiered excess energy credit , from our Nevada 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 Las Vegas in 2026?
About $19,040 for a typical 8 kW system at $2.38 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 Nevada 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 Las Vegas?
Roughly 17.9 years on this model, using Las Vegas’s own production figure of 1,689 kWh per kW and its own utility tariff (15.33¢/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 Las Vegas better or worse for solar than the rest of Nevada?
Against the state figure, Las Vegas runs 0.9% below Nevada’s 1,705 kWh per kW — a payback 2.9 years shorter than the statewide 20.8-year estimate on the same hardware at the same price.
Is solar worth it in Las Vegas in 2026?
Las Vegas has among the best solar resources in the country at 1,689 kWh per kW, and a payback near 17.9 years anyway. At 15.33¢/kWh with tiered net billing, cheap electricity is the binding constraint, not sun.
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.
