A worked example: 8 kW in North Dakota
An 8 kW system — about 19 × 425-watt panels — at North Dakota's assumed installed cost of $2.50–$3.30 per watt runs roughly $20,000–$26,400 before incentives. At about 1,320 kWh of production per installed kW, it would generate around 10,560 kWh per year. Valuing self-consumed electricity at the assumed $0.11/kWh retail rate and exports conservatively, first-year savings land near $957 — a simple payback of roughly 21–28 years.
There is no federal tax credit in that math: the Section 25D residential credit ended for systems installed after December 31, 2025. State or utility incentives, where they exist, would shorten payback from here.
Average cost of solar panels in North Dakota by system size
Most North Dakota quotes land between 6 and 12 kW. At the state's assumed $2.50–$3.30 per watt, here is what each size costs to install, what it produces, and how long it takes to pay for itself on electricity savings alone — no incentives applied.
| System size | Panels | Installed cost | Annual production | Est. payback |
|---|---|---|---|---|
| 6 kW | 15 | $15,000–$19,800 | 7,920 kWh | 21–28 yrs |
| 8 kW | 19 | $20,000–$26,400 | 10,560 kWh | 21–28 yrs |
| 10 kW | 24 | $25,000–$33,000 | 13,200 kWh | 21–28 yrs |
| 12 kW | 29 | $30,000–$39,600 | 15,840 kWh | 21–28 yrs |
Size should follow your electricity usage, not a round number — these are reference points, not a recommendation. Note that cost per watt rises on smaller systems, because permitting, labor and the inverter do not shrink with the array.
What solar costs per kWh in North Dakota
Spread across a 25-year life, with 0.5%/yr panel degradation and no financing cost, solar electricity in North Dakota works out to roughly 8.0¢–10.6¢ per kilowatt-hour. The North Dakota retail rate this page assumes is 11.0¢. That gap — not the sticker price — is what determines whether solar pays here, and it is why a sunnier state with cheap electricity can be a worse investment than a cloudier one with expensive electricity. See how every state compares on cost per kWh.
Net metering and export rates in North Dakota
North Dakota requires net metering up to 100 kW for regulated utilities, with excess credited at avoided cost. Co-ops set their own policies.
Export rules are worth reading as an incentive, because they set what every kilowatt-hour you do not use on site is worth — see how North Dakota compares with every other state on net metering.
North Dakota solar incentives
North Dakota offers a property tax exemption for solar but no state tax credit or rebate.
The most valuable program is property tax exemption. With no federal credit for 2026 installs, state and utility programs are now the whole picture — see the full North Dakota incentives guide.
What changes a North Dakota solar quote?
Equipment, roof condition, electrical upgrades, permitting, labor, system size, batteries and financing can all change the installed price. Savings also depend on the specific utility rate, how much solar electricity the home uses directly, and what the utility pays for exports.
Frequently asked questions
What is the average cost of solar panels in North Dakota?
The average installed cost in North Dakota runs $2.50–$3.30 per watt before incentives, which puts a 6 kW system at $15,000–$19,800, an 8 kW at $20,000–$26,400, and a 10 kW at $25,000–$33,000. Spread over a 25-year life, that works out to about 8.0¢–10.6¢ per kilowatt-hour, against a North Dakota retail rate assumed at 11.0¢.
How much does it cost to install solar panels in North Dakota?
Installation is not priced separately — the $2.50–$3.30 per watt above is a turnkey figure covering panels, inverter, racking, labor, permitting and interconnection. What moves it most in ND is roof complexity, whether the main panel needs upgrading, and whether a battery is included. Expect a site visit to change any online estimate, including this one.
How much do solar panels cost in North Dakota?
Using an assumed installed cost of $2.50–$3.30 per watt, a typical 8 kW home system in North Dakota costs roughly $20,000–$26,400 before incentives. Smaller and larger systems scale roughly with size, though small systems cost more per watt.
Is solar worth it in North Dakota?
With North Dakota electricity around $0.11/kWh and production around 1,320 kWh per installed kW per year, an 8 kW system could save roughly $957 in year one, for a simple payback of about 21–28 years with no federal credit. Whether that is "worth it" depends on your rate plan, export compensation, roof, and how long you plan to stay in the home.
How many solar panels do I need in North Dakota?
It depends on your electricity usage, not your roof. At North Dakota's assumed 1,320 kWh per installed kW, a 6 kW system (about 15 panels at 425 watts) generates roughly 7,920 kWh a year, and a 10 kW system (about 24 panels) roughly 13,200 kWh. Compare that against your annual kWh from a utility bill — our calculator sizes it from your monthly bill in about a minute.
Does North Dakota have net metering?
North Dakota requires net metering up to 100 kW for regulated utilities, with excess credited at avoided cost. Co-ops set their own policies.
What solar incentives does North Dakota offer in 2026?
North Dakota offers a property tax exemption for solar but no state tax credit or rebate. Note that the federal Section 25D residential credit ended for systems installed after December 31, 2025, so state, local and utility programs are now the main incentives for purchased systems.
Is there still a federal solar tax credit in North Dakota?
No — the 30% federal residential clean energy credit (Section 25D) ended for systems installed after December 31, 2025 under the One Big Beautiful Bill Act. Leased or PPA systems may still benefit indirectly because the system owner can claim the commercial 48E credit through 2027.
