Solar Panel Cost in Las Vegas, NV (2026 Estimate)

BySunMetricLab Editorial Team·Independent solar research and calculators

Data last updated September 10, 2026

Las Vegas averages about 6.4 peak sun hours a day (well above the national average, matching the Nevada statewide average), and pairs with Nevada's approximate residential rate near 15¢/kWh. In the model used here, an 8 kW system produces roughly 14,950 kWh a year and trims about $2,200 off annual electricity costs, paying back its net cost in about 6.7 years . Local shading, roof, and your utility's export terms move the real figure.

Estimated system cost and payback in Las Vegas

Costs assume roughly $2.70/watt installed; the net column applies a 30% federal credit for comparison with quotes that include it. Savings use Las Vegas's sun hours and Nevada's rate.

The 30% federal Residential Clean Energy Credit ended for systems paid for after December 31, 2025 under the 2025 federal budget law. Net-after-credit figures apply only if you still qualify (for example a 2025 expenditure, or a leased system where the installer passes a credit through). Confirm with a tax professional.

Net metering and utilities around Las Vegas

Nevada restored net metering in 2017 with Assembly Bill 405 after a period in which exports had been cut to wholesale value and the residential market collapsed. The law set four tiers of export credit as a percentage of retail, stepping down from 95 percent to 75 percent as each 80 MW block filled, and new NV Energy customers have been in the final 75 percent tier for several years. Once enrolled, that percentage is guaranteed for 20 years, and unused credits roll over indefinitely rather than resetting annually.

NV Energy, operating as Nevada Power in the south and Sierra Pacific Power in the north, serves nearly 90 percent of the state, with Valley Electric Association, Overton Power, Mt. Wheeler Power and a few municipal systems covering the rest. Rates in southern Nevada are moderate, and summer cooling loads in Las Vegas are enormous, so a rooftop system displaces a large volume of expensive afternoon consumption. NV Energy's optional time-of-use plan prices late-afternoon and evening summer hours much higher than the rest of the day, which helps solar-plus-storage households and can hurt a solar-only home whose usage peaks after sunset.
