Solar panels in Las Vegas, Nevada: output, savings and payback
Solar panels in Las Vegas produce about 1,799 kWh a year for each kW installed, 19% more than the average of the 400 US cities in our data (1,517 kWh). Among the 5 Nevada cities we cover, it ranks 3rd of 5 for solar output, against an average there of 1,776 kWh.
Nevada’s average residential electricity price for January to August 2026 was 13.36¢ per kWh, 4.83¢ below the US average of 18.19¢, according to the Energy Information Administration.
For a home using the US average of 899 kWh a month, a 6.0 kW system would cover a year’s use and save about $1,441 in its first year, or $49,135 over 25 years. With the average sunshine of the 400 US cities in our data, the same home would need a 7.1 kW system. Because Las Vegas gets more sun, it needs 16% less capacity to cover the same use, so at any price per watt the system costs 16% less and pays for itself sooner.

Solar panels in Las Vegas: questions
- How much electricity do solar panels produce in Las Vegas, Nevada?
- About 1,799 kWh a year for each kW of panels, for a roof-mounted, south-facing array at a 30° tilt with 14% system losses (PVWatts). A 6.0 kW system would make about 10,788 kWh in its first year. Shade, a different roof angle or an east or west-facing roof will change this.
- How much could solar panels save in Las Vegas, Nevada?
- At Nevada’s average residential price of 13.36¢ per kWh, a 6.0 kW system sized for an average US home would save about $1,441 in its first year and $49,135 over 25 years. That assumes the home uses all the power the panels make, electricity prices rise 3% a year and panel output falls 0.5% a year. Power sent to the grid is counted at zero. At the US average price of 18.19¢, the first-year figure would be $1,962.
- How long do solar panels take to pay back in Las Vegas, Nevada?
- It depends on the installed price on your quote, which varies by installer and system, and we do not have a verified US average to use. Enter your quote in the calculator on this page: Las Vegas’s solar output and Nevada’s electricity price are already filled in. Every $0.10 per watt adds about $600 to the price of a 6.0 kW system.
