Solar in North Dakota
What a typical 8 kW rooftop system generates and saves in North Dakota, from NREL sun data and the local power rate. A planning estimate, not a quote.
Based on 1350 kWh per kW per year of sun in North Dakota, a 12¢ per kWh rate, and $3.00 per watt installed.
In North Dakota, the payback is on the long side. North Dakota has fair sun but the lowest rate in the country, so dollar savings are small and the payback is among the longest.

Sun from NREL PVWatts, rate from the US Energy Information Administration, cost from 2026 US cost benchmarks. Last reviewed 2026-06-30. This is a planning estimate, not a quote. It uses a state-level representative figure for sun and electricity price; your roof, shading, tilt, exact utility rate, net-metering rules, financing, and incentives will change the result. The payback shown is before incentives; the 30 percent federal solar tax credit and any state or utility programs shorten it. Run PVWatts for your address and get two or three local quotes before deciding. Figures last reviewed on the verified date.
