North Dakota solar calculator
Size a North Dakota home solar system from your electric bill — kW, panel count, roof area, true cost with no federal credit for 2026 installs, and payback.
Quick answer: At $0.134/kWh and 4.5 peak sun hours, a $200/month bill needs about 14.35 kW — 35 × 410 W panels covering ~70 m². Gross cost is ~$57,687 with no federal credit for systems installed after 2025, offsetting $2,400 a year for a ~24.0 year payback.
Your details
Ballpark, not gospel. Ballpark, not gospel. Sized at 78% real-world output with the North Dakota sun-hour average (4.5 peak sun hours) — confirm shading, roof angle and your utility’s terms with a local installer before buying, since co-ops and municipals set their own rules. North Dakota’s net energy billing rule applies only to investor-owned utilities and credits monthly surplus at avoided cost (~2–5¢/kWh), not retail. The calculator values all generation at your retail rate; exports earn far less, so real savings track self-consumption and batteries.
The 30% credit ended — what changed
The residential clean energy credit (26 U.S.C. § 25D) gave homeowners a 30% credit on solar installed from 2022 through 2025. The July 2025 tax law ended it: no credit is available for property placed in service after December 31, 2025. That is why every figure on this page is ~30% higher than pre-2026 guides show. If your system went live by the end of 2025, tick the box above to see the credit applied; leased systems may still benefit because the leasing company claims the commercial credit.

Solar in North Dakota: the details
Solar cost in North Dakota
North Dakota is the priciest install market in this batch — a thin installer market pushes costs well above the national band. The EnergySage marketplace averaged about $4.02 per watt installed in 2026, with market quotes typically landing $3.41–$4.62/W — above the $2.50–$3.50/W national band. A typical ~13 kW system grosses around $52,300, with no federal credit for 2026 homeowner installs.
What moves the number: roof complexity, panel tier, and how competitive the quote market is in your metro. Get at least three quotes — spreads of $0.50/W between installers are common.
Export rules: getting paid for surplus power
North Dakota’s net energy billing rule (N.D. Admin. Code 69-09-07) applies only to investor-owned utilities (Xcel, Otter Tail, MDU). It credits monthly surplus exports at avoided cost — roughly 2–5¢/kWh — not retail. Co-ops and municipals set their own terms, and many don’t buy back at all.
Practical takeaway: exported kWh earn only ~2–5 cents while self-consumed kWh save the full ~12–13 cents, so size strictly to daytime use. Every kWh you export is nearly worthless — self-consumption (and a battery if outages worry you) is the whole game.
North Dakota solar incentives
North Dakota offers no state solar tax credit; the only state-level financial benefit is a five-year property tax exemption on the assessed value solar adds to a home — roughly $500–$1,200 over the term depending on the county mill levy. With no federal credit for 2026 installs, there is no meaningful incentive stack to count on.
Is solar worth it in North Dakota?
Verdict: hard to justify on the numbers. The calculator puts a $200/month bill at a ~24-year payback with no federal credit — expensive installs, low rates, modest sun, and 2–5¢ avoided-cost exports make this the weakest case in the batch. Solar here is a resilience or values play, not an investment. If you proceed anyway, size strictly to daytime use and self-consume everything — exporting is nearly worthless.
Questions people actually ask
Straight answers, no fluff. Then run your own numbers above.
How many solar panels do I need in North Dakota?
It follows your bill. At the North Dakota average of $0.134/kWh and 4.5 peak sun hours, a $200/month bill needs about a 14.35 kW system — roughly 35 × 410 W panels covering ~70 m² of roof.
What is the average cost of solar panels in North Dakota in 2026?
The EnergySage marketplace averaged about $4.02 per watt installed in 2026, with market quotes typically $3.41–$4.62/W — above the national $2.50–$3.50/W band, due to a thin installer market. A typical ~13 kW system grosses around $52,300, with no federal credit for 2026 homeowner installs.
Does North Dakota have net metering?
Only in a limited form. The net energy billing rule (N.D. Admin. Code 69-09-07) applies only to investor-owned utilities (Xcel, Otter Tail, MDU) and credits monthly surplus exports at avoided cost (~2–5¢/kWh), not retail; co-ops and municipals set their own terms.
Does North Dakota offer any solar tax credit or rebate?
No state solar tax credit. The only state-level benefit is a five-year property tax exemption on the assessed value solar adds to a home (roughly $500–$1,200 over the term depending on the county mill levy).
Is the 30% federal solar tax credit still available?
Not for homeowner purchases anymore. The residential clean energy credit (26 U.S.C. § 25D) is not available for property placed in service after December 31, 2025, under the July 2025 tax law (Public Law 119-21). Systems installed by the end of 2025 can still claim 30%, and leased systems may still benefit because the leasing company claims the commercial credit instead.

Is solar worth it in North Dakota?
The calculator puts a $200/month bill at a ~24-year payback with no federal credit — expensive installs, low rates, and 2–5¢ export credits make this a hard case. If you go ahead, size strictly to daytime use and self-consume everything.
