Solar Energy in North Dakota: What You Need to Know
North Dakota has moderate sun hours and low electricity rates, making solar payback periods longer. Wind energy dominates the renewable landscape. Cold winters do improve panel efficiency.
Electricity Rates in North Dakota
The average residential electricity rate in North Dakota is 11.5 cents per kWh, which is below the national average of approximately 16 cents per kWh. Lower electricity rates mean the payback period is longer, but the 25-year savings are still substantial. As electricity rates continue to rise (averaging 3% per year nationally), the value of solar ownership increases over time.
Peak Sun Hours and Solar Production
North Dakota averages 4.2 peak sun hours per day, which is moderate but still viable for residential solar. Many successful solar installations operate across the Northeast and Midwest with similar sun hours. Modern panels are increasingly efficient even in diffuse light conditions. A 6 kW system in North Dakota produces approximately 7,358 kWh per year, accounting for standard system efficiency losses and typical weather patterns.
North Dakota Solar Incentives and Programs
No state tax credit. Net metering at avoided-cost rate. Property tax exemption for renewable energy systems. No sales tax exemption. Income tax credit for geothermal and wind but not specifically solar.
