Quick answer
North Dakota solar economics depend on your roof, utility and quote. This page uses illustrative assumptions of 4.8 peak sun hours, $2.95/W and 10.0 cents/kWh; these are not verified current market averages or account rates.
Notes updated 2026-07-24
- Best for
- North Dakota homeowners comparing solar costs, incentives, and payback assumptions.
- Inputs needed
- annual kWh usage, utility rate, installed $/W, net-metering policy
- Formula used
- Planning production = system kW x peak sun hours x 365 x (1 - 14.08% losses). Retail-value ceiling = production x assumed retail price; actual export value can be lower.
- Method references
- state incentive data, utility tariff checks, Wattcrunch price benchmarks
Key fact about North Dakota solar
North Dakota's 15% state tax credit (up to $3,000) helps but doesn't fully overcome low electricity rates and cold winters. Fargo and Bismarck have the most installer presence.

Illustrative 8 kW system in North Dakota
Annual production
12,043 kWh
Retail-value ceiling, not savings
$1,204
System cost (est.)
$23,600
Includes 14.08% planning losses. Valuing all production at retail is a ceiling, not a net-billing savings estimate; actual self-use, export rates and ownership costs change the result. No new Section 25D homeowner credit in 2026.
Worked example
North Dakota: a transparent 8 kW planning example
This example shows how the published North Dakota assumptions flow through a simple first-pass calculation.
Example household usage
10,800 kWh/year
Estimated production
12,043 kWh/year
Rate used in the example
10.0 cents/kWh
Retail-value ceiling, not bill savings
$1,204/year before ownership costs
North Dakota Net Metering Policy
Full retail net metering (PSC rules)
North Dakota requires full retail net metering for IOUs under PSC rules. MDU and Xcel Energy ND must credit excess at retail rate. Annual settlement with unused credits at avoided cost.
North Dakota Solar Incentives
Programs require eligibility checks and cannot always be combined. Federal 25D credit is $0 for new homeowner-owned systems in 2026.
- ✓State income tax credit: 15% of cost (up to $3,000)
- ✓Property tax exemption on added value

State-specific decision guide
What to verify before signing a North Dakota solar quote
In North Dakota, the financial result depends on more than sunshine or the headline installation price. Confirm the export rule, program eligibility date, and interconnection timeline for your exact utility before treating a payback estimate as a promise.
Export value
This page models full retail net metering (psc rules). Ask which tariff and export credit apply to your account, not only which program name appears in the proposal.
Incentive eligibility
Check equipment, income, installer, application, and placed-in-service rules before subtracting an incentive from the quote. Programs can close or change terms.
Interconnection
Budget for the published 4–8 weeks and confirm who pays for a required meter, service upgrade, or engineering review.
Source trail: production assumptions use NREL PVWatts; incentive discovery should be checked against DSIRE; electricity-market context is available from the EIA. Confirm final tax treatment with the IRS and your utility.
