Solar site surveys in Nevada

A technician on the roof, in the attic and at the service panel, with the survey read against the code editions, AHJs and utilities that apply in Nevada.

Short answer

Nevada has no statewide electrical or residential code for private homes, so each city and county adopts its own; Clark County, Las Vegas and Henderson moved to the 2024 I-Codes and 2023 NEC with shared Southern Nevada amendments in January 2026. NV Energy credits new rooftop solar exports at 75% of the retail rate, and since October 2025 new Northern Nevada customers are netted in 15-minute intervals. Surveys should plan for extreme summer heat, concrete tile roofs and NV Energy's rules on where the meter and disconnect sit.

What changes in Nevada

The capture spec is the same everywhere. What the engineer and the plan reviewer read it against is not.

NV · METROSLas Vegas
Code stack
LOCALNEC 2023 · Clark CountyNational Electrical Code · effective Jan 11, 2026. Nevada leaves NEC adoption to local governments. Unincorporated Clark County adopted the 2023 NEC with Southern Nevada amendments effective January 11, 2026, the City of Las Vegas on January 5, 2026 and Henderson for submittals from January 2, 2026, while Washoe County adopted it effective July 1, 2025, so confirm the edition with the AHJ.1,2,3,4
LOCALIRC 2024 · Clark CountyThe Southern Nevada amendments to the 2024 IRC were written by a regional building officials' committee and then adopted separately by each jurisdiction; Clark County's version took effect January 11, 2026. Northern Nevada jurisdictions use their own regional amendments, and Washoe County has required the 2024 editions for all submittals since January 1, 2026.5,4,6
LOCALIFC 2024 · Clark CountyClark County adopted the 2024 IFC with county amendments by ordinance in December 2025, effective January 2026. The State Fire Marshal began enforcing the 2024 codes on January 1, 2026 where it is the fire authority, while cities such as Las Vegas and Henderson adopt their own fire code amendments.7,8,2,3
Rooftop fire access. In unincorporated Clark County, plan review checks rooftop PV clearances under the 2024 IFC Section 1205 and IRC R329 instead of a separate fire permit: at least two 36-inch eave-to-ridge pathways on separate roof planes (one on the street or driveway side), a pathway on every plane with modules, and 18- or 36-inch ridge setbacks depending on whether the array covers more than 33% of the roof. Roofs at 2:12 slope or less are exempt for IRC homes, and other AHJs may differ.9

Climate and site factors

Heat

Las Vegas hit 120°F on July 7, 2024, its highest temperature on record. Nevada OSHA's heat illness regulation (R131-24) has been enforced since April 29, 2025 and requires employers with more than 10 employees to complete a job hazard analysis for heat exposure, so plan roof time and crew precautions accordingly.10,11,12,13

Roof types

Concrete tile is a common roofing material on Las Vegas-area homes, which affects mounting hardware and makes tile breakage and underlayment condition worth recording. In Clark County, a prescriptive path waives detailed structural engineering for flush, roof-parallel arrays of 4 psf or less with attachments no more than 48 inches apart.14,9

Wind / snow

Clark County's amended 2024 IRC design table lists a 98 mph design wind speed and ground snow loads that rise with elevation, from 5 psf below 1,600 feet to 20 psf below 3,900 feet; above 3,900 feet the IBC criteria apply, so record the site elevation.5

Meter and disconnect

NV Energy's net metering standard requires a visible-break, lockable disconnect within 10 feet of the service entrance disconnect, with a clear line of sight between them, and generation meter sockets generally within 10 feet of the service equipment. Survey the service entrance area with these distances in mind.15

HOAs

Nevada HOAs and deed restrictions cannot prohibit solar or cut its performance by more than 10% without a comparable alternative, and rules banning black solar glazing count as unreasonable. Record any HOA placement request because it may affect which roof planes are used.16,17

Permitting in Nevada

Who reviews the plan set, and what the state layers on top.

Utilities and interconnection

NV Energy's two operating companies serve most Nevadans, while rural cooperatives and public power districts serve other areas, such as Overton Power District No. 5 (Mesquite and northeast Clark County), Valley Electric Association (Pahrump) and Boulder City's municipal utility. These smaller utilities set their own solar terms.22,23,24

NV Energy (Nevada Power Company) NV Energy

Serves Las Vegas and the surrounding parts of Southern Nevada; installers apply through the NV Energy net metering PowerClerk portal, with a $189 application fee in the south, and the account moves to the net metering rate after permission to operate.21,25

Interconnection page ↗

NV Energy (Sierra Pacific Power Company) NV Energy North

Serves Northern Nevada, including the Reno area; uses the same PowerClerk process ($184 application fee), and new customers approved since October 1, 2025 are billed with 15-minute netting.21,25

Interconnection page ↗

City of Boulder City Utilities Boulder City

City-owned utility: net metered systems need a city building permit and inspection, a signed interconnection agreement and a city-witnessed interconnection test, and are capped at 80% of the customer's average yearly use.24

Interconnection page ↗
Export compensation. Under AB 405 (2017), NV Energy's net metering credit stepped down through three 80 MW tiers, and the last one closed in June 2020, so new systems of 25 kW or less get Tier 4: 75% of the retail rate, kept for 20 years at that location. Southern Nevada still nets monthly, but in Northern Nevada, customers approved on or after October 1, 2025 are netted every 15 minutes, with excess in each interval valued at 75% of retail. The PUCN also approved a daily demand charge for Southern Nevada residential customers, now scheduled for January 1, 2027, and these changes face legal challenges.26,21,27,28,29

Nevada solar survey FAQ

Which NEC edition applies to solar in Nevada?

There is no statewide edition for private homes; each city and county adopts its own. As of September 2026, the Southern Nevada jurisdictions and Washoe County enforce the 2023 NEC (Clark County since January 11, 2026, Las Vegas since January 5, 2026), but confirm the edition with the AHJ.30,2,4

How does NV Energy credit rooftop solar exports?

New systems of 25 kW or less go on the Tier 4 net metering rate, which values excess energy at 75% of the retail rate and is kept for 20 years. In Northern Nevada, customers approved since October 1, 2025 are netted in 15-minute intervals rather than monthly.26,21

Can a Nevada HOA stop a homeowner from installing solar?

No. NRS 111.239 and NRS 278.0208 void covenants that prohibit or unreasonably restrict solar, including rules that cut performance by more than 10% without a comparable alternative. Homeowners can ask the Governor's Office of Energy for a determination.16,17

How big can a net-metered system be in Nevada?

NV Energy will not approve a system sized to produce more than 100% of the customer's annual energy use, based on the highest 12 consecutive months in the last 24. Systems over 25 kW and up to 1 MW go on the NMR-B rate instead of Tier 4.21

Do all Nevada utilities follow NV Energy's net metering rules?

No. Cooperatives and municipal utilities set their own terms. Boulder City, for example, caps systems at 80% of average yearly use and credits monthly excess at its average wholesale energy cost, with credits expiring after 12 months.24,22
