Why North Dakota lands where it does
Electricity in North Dakota is cheap at 11.3 cents a kilowatt-hour, and that is the problem. Solar competes with what you already pay, so when grid power is inexpensive the savings are small however much sun there is. This is the single biggest reason payback here is long.
At 4.4 peak sun hours a day, production is close to the national average.
Local and utility incentives are not included above, because they change too often for any published list to stay right. If North Dakota offers a rebate, enter it in the calculator and the payback will shorten accordingly.
