Solar panels in Raleigh, North Carolina: output, savings and payback

Solar panels in Raleigh produce about 1,395 kWh a year for each kW installed, 8% 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 11th 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 7.7 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 Raleigh gets less sun, it needs 9% more capacity to cover the same use, so at any price per watt the system costs 9% more and pays for itself later.

There is no verified US installed-price figure yet, so add the price per watt from your installer’s quote in the calculator below to see the payback period for Raleigh.

%

Share of the panels’ output your home uses as it is made. 100% assumes all of it offsets power you would otherwise buy, up to your annual use.

A battery only adds savings when you use less than 100% of your solar power directly. Lower “Used directly at home” under assumptions to model that.

Solar panels in Raleigh: questions

How much electricity do solar panels produce in Raleigh, North Carolina?
About 1,395 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 7.7 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 Raleigh, North Carolina?
At North Carolina’s average residential price of 14.94¢ per kWh, a 7.7 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 Raleigh, 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: Raleigh’s solar output and North Carolina’s electricity price are already filled in. Every $0.10 per watt adds about $770 to the price of a 7.7 kW system.
What do homes in Raleigh, North Carolina pay for electricity?
North Carolina’s average residential price for January to August 2026 was 14.94¢ per kWh, against 18.19¢ for the US as a whole (EIA Electric Power Monthly, Table 5.6.B). Your own rate depends on your utility and plan, so use the figure from your bill in the calculator if you can.
