Solar in Bismarck: What Homeowners Should Know
Bismarck sees an average of 4.8 peak sun hours per day, which is what ultimately determines how much electricity a rooftop system produces here. A standard 8 kW system (about 20 panels) generates roughly 11,213 kWh each year in Bismarck — and paired with North Dakota's local electricity rate of $0.100/kWh, that's where the savings come from.
At those numbers, a Bismarck homeowner saves about $93/month ($1,121/year). Against a $23,200 system cost (about $20,200 after North Dakota state incentives), that works out to a payback of about 18 years, after which the system produces essentially free power for two decades — an estimated $18,100 in lifetime savings. Note: the 30% federal tax credit expired at the end of 2025 for purchased systems, though a solar lease or PPA can still pass it through. The local grid is served by Montana-Dakota Utilities, whose net metering policy directly affects how much credit you earn for surplus power.
