Are Solar Panels Worth It in North Dakota? 2026 Cost & Payback
A typical North Dakota household uses about 1,100 kWh a month and pays 11.92¢ per kWh — roughly $131 a month. Covering that takes a 9.0 kW system costing about $27,011, which pays for itself in about 14 yr 11 mo.

Net metering in North Dakota
North Dakota credits every exported kilowatt-hour at the full retail rate, so the grid effectively acts as a free battery. This is the most favourable arrangement and shortens payback considerably.
Common questions
How much do solar panels cost in North Dakota?
At around $3.00 per watt installed, the 9.0 kW system a typical North Dakota home needs works out to roughly $27,011 before any incentives. The 30% federal residential credit no longer applies to systems purchased after 31 December 2025, so that is also the net price.
How long do solar panels take to pay for themselves in North Dakota?
About 14 yr 11 mo. That accounts for panel output falling roughly 0.5% a year and utility rates rising around 2.5% a year, which pull the answer in opposite directions.
Does North Dakota have net metering?
North Dakota credits every exported kilowatt-hour at the full retail rate, so the grid effectively acts as a free battery. This is the most favourable arrangement and shortens payback considerably.
How much will I save over 25 years in North Dakota?
Roughly $23,306 after the system has paid for itself — about 86% return on the up-front cost. Savings are larger if electricity prices rise faster than 2.5% a year.
Is North Dakota sunny enough for solar?
North Dakota averages about 4.92 peak sun hours a day, and a well-oriented array there yields roughly 1,464 kWh per kW installed each year. Sunlight matters less than most people assume — electricity price is the bigger driver, which is why cloudy, expensive states often beat sunny, cheap ones.
How we calculate this
We model 25 years one year at a time rather than dividing cost by first-year savings. Panel output falls 0.5% each year and electricity prices rise 2.5% each year, so the payback figure reflects both.
Production uses the modelled AC yield for North Dakota rather than a flat efficiency factor. A peak-sun-hours approximation runs about 9% high, which is enough to make payback look a year faster than it is.
We assume 40% of generation is used in the home as it is produced, with the rest exported and credited according to the state's net metering rules.
