Solar panels in Charlotte, North Carolina: output, savings and payback
Solar panels in Charlotte produce about 1,417 kWh a year for each kW installed, 7% less than the average of the 400 US cities in our data (1,517 kWh). Among the 12 North Carolina cities we cover, it ranks 8th of 12 for solar output, against an average there of 1,441 kWh.
North Carolina’s average residential electricity price for January to August 2026 was 14.94¢ per kWh, 3.25¢ 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 7.6 kW system would cover a year’s use and save about $1,612 in its first year, or $54,946 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 Charlotte gets less sun, it needs 7% more capacity to cover the same use, so at any price per watt the system costs 7% more and pays for itself later.

Solar panels in Charlotte: questions
- How much electricity do solar panels produce in Charlotte, North Carolina?
- About 1,417 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 7.6 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 Charlotte, North Carolina?
- At North Carolina’s average residential price of 14.94¢ per kWh, a 7.6 kW system sized for an average US home would save about $1,612 in its first year and $54,946 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 Charlotte, North Carolina?
- 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: Charlotte’s solar output and North Carolina’s electricity price are already filled in. Every $0.10 per watt adds about $760 to the price of a 7.6 kW system.
