Solar in Nevada costs about $2.68 per watt, so the typical 9.29 kW system runs about $24,897 before incentives, with a best-case payback of about 11.1 years. Since October 1, 2025, the side of the state you live on changes that math: new Sierra Pacific customers around Reno net exports every 15 minutes, while Nevada Power customers around Las Vegas still net by the month.

Every 15 minutes in Reno, once a month in Las Vegas: Nevada’s two netting clocks
Both utilities pay the same 75% export rate. What differs is how often your meter settles up. A monthly ledger forgives a midday surplus. A 15-minute one does not. Court challenges to the change were denied in February 2026, so this is settled, not pending.
Sierra Pacific, northern Nevada
About 25% of households. For applications on or after October 1, 2025, any surplus in a 15-minute interval is exported at 75% of retail right away. A battery matters a lot: storing midday output keeps it at full retail value.
Nevada Power, southern Nevada
About 70% of households. A midday surplus offsets anything you import later that month at full value. A battery helps less, because the monthly ledger already does much of that work.
Existing customers on both sides keep their tier and their monthly netting.
Size and equip for your side of the stateIn the north, every kilowatt-hour your house is not using the moment it is made leaves at the Tier 4 credit instead of offsetting a full-price import later. That turns a battery in Reno from a nice-to-have into part of the financial case. In Las Vegas, the monthly ledger still absorbs the same surplus for you.

75% of retail, fixed for 20 years: what Tier 4 gives a new Nevada customer
Under AB 405, Nevada replaced one-to-one net metering with a tiered tariff. New residential customers up to 25 kW enter Tier 4. Tiers 1, 2 and 3, at 95%, 88% and 81%, closed between 2018 and 2020 and are not coming back.
Rates here have climbed among the fastest in the country. A locked share of a rising number is a genuinely useful position.
The 100% sizing capNV Energy limits net-metered home systems to 100% of your yearly use (or the class demand limit, if larger), measured on what your meter has actually recorded. You cannot size for a future pool, workshop or second EV. Size for what the meter has seen.
A demand charge is comingA new residential demand charge has been postponed to January 1, 2027. Ask about it before you finalize anything.
11.1 years if you use it all: the Nevada best-case payback
Cheap installs and strong sun work together here. Each kilowatt makes about 1,801 kWh a year in Nevada sun. Fast rate growth works in your favor too. For the national picture, see state-by-state solar pricing.

Gross cost before incentives, with the yearly output each size makes at about 1,801 kWh per kilowatt.
Gross cost at $2.68 per watt. Output uses 1,801 kWh per kW. Exports earn the Tier 4 credit, 75% of what your own utility charges.
Buying outright with no federal credit, or letting a Nevada lease carry it
For systems you own whose installation is completed after December 31, 2025, under Public Law 119-21.
IRSNevada authorizes both, so third-party ownership is a genuine route if you want someone else carrying the equipment. The incentives then follow that owner, not you.
Four Nevada buyers and quotes that call for a no
Nevada’s numbers are strong, but not for every home or every proposal.
- Northern homes with no battery and nobody in during the day. Under 15-minute netting this profile loses most, and a monthly-netting quote will model it optimistically.
- A proposal that does not say which netting rule applies. After October 1, 2025 that omission is not a detail. Ask whether the model assumes monthly or 15-minute intervals, and get the answer in writing.
- Buyers planning around future use. The 100% cap is measured against what you have actually used, not what you intend to use.
- Anyone quoted well above $2.68 per watt. Nevada is the 8th lowest-priced install market of 51. Paying mid-table prices here gives up the state’s main advantage.

More on Nevada solar costs
Frequently asked questions
How much do solar panels cost in Nevada in 2026?
About $2.68 per watt installed, the 8th lowest of 51 (EcoGen Solar Cost Index, September 2026 Edition). The typical system, the median size Nevada homeowners installed in 2025, is 9.29 kW, roughly $24,897 before incentives. Strong sunlight, about 1,801 kWh per kW a year, makes each kilowatt work hard.
Does Nevada still have net metering?
Not one-to-one. Nevada uses a tiered successor tariff under AB 405, and new residential customers up to 25 kW enter Tier 4, where excess generation is credited at 75% of the utility’s energy rate: 8.347¢ per kWh around Las Vegas and 8.055¢ around Reno from October 1, 2026. That rate is locked for 20 years at your address, which is valuable in a state where rates have risen 4.56% a year.
What is 15-minute net metering in northern Nevada?
For Sierra Pacific applications on or after October 1, 2025, exports are netted every 15 minutes rather than monthly: any surplus within an interval is sold at 75% of retail immediately, instead of offsetting a later import at full value. Nevada Power in the south remains on monthly netting. Court challenges were denied in February 2026, so the change stands.
What is the solar payback period in Nevada?
About 11.1 years in the best case, if every kWh the 9.29 kW system makes replaces power at the 13.36¢ state average. Exports earn the Tier 4 credit, 75% of retail, so most homes take longer. Strong sunlight, low installed prices and fast rate growth all work together here.
How big a solar system can I install in Nevada?
Up to 25 kW for residential customers, and no larger than 100% of your yearly use (or the class demand limit, if larger). That second limit is measured against what your meter has actually recorded, so you cannot size for a pool, workshop or additional electric vehicle you have not bought yet.
How we calculate these costs
Cost figures use Nevada’s entry in the EcoGen Solar Cost Index (September 2026 Edition), $2.68 per watt, prices as of September 25, 2026. Payback is a simple best case: the typical cost divided by the year-one value of the power the system makes at the 13.36¢ state average, with no federal residential credit for owner-purchased systems, no rate growth and no export discount. The 9.29 kW typical size is Berkeley Lab’s 2025 median for Nevada single-family installs (4,924 systems). The 15-minute interval netting applies to Sierra Pacific applications on or after October 1, 2025 and is described from the Public Utilities Commission docket record.
