What North Dakota still offers after the federal credit ended
Every incentive on this page is verified against North Dakota government sources - and the expired ones salespeople still quote are called out.
The 30% federal solar tax credit ended for installations finished after December 31, 2025 - Mandan systems completed in 2026 get $0 from it.
Under North Dakota's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.
Installed home solar for Mandan homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
The federal Residential Clean Energy Credit - the 30% one every solar ad still quotes - was repealed by the One Big Beautiful Bill Act signed July 4, 2025. Per the IRS, it is not available for any system placed in service after December 31, 2025, and 'placed in service' means the installation completion date, not the contract date.
If a salesperson in Mandan tells you a 30% federal tax credit applies to your 2026 installation, they are quoting a dead law. What may still exist: North Dakota's own incentives and tax treatment, listed below, and lease/PPA arrangements where a company claims commercial credits - in which case the credit belongs to them, not you.

North Dakota rules that decide your payback
| Rule | North Dakota status |
|---|---|
| Export compensation (net metering) | North Dakota rule entitles customer generators with a design capacity of 100 kilowatts or less — which covers every residential rooftop system — to net energy billing in which the system's output reverses the utility's sales meter, while the general standard for a utility's purchases from qualifying facilities is the utility's avoided cost rather than the retail rate. |
| State incentive | No state-level incentive; utility rebates may apply |
| Property tax on added home value | Excluded |
The net energy billing entitlement binds only investor-owned 'electric public utilities' as defined in N.D.C.C. 49-03-01.5 — rural electric cooperatives, which serve much of North Dakota, are not covered, a gap underscored by a 1991 Legislative Council committee objection noting the legislature had defeated a bill that would have extended net energy billing to cooperatives.

What this means for Mandan roofs
The honest 2026 answer for Mandan: solar pays back slower without the 30% credit - paybacks that ran 7-10 years often now run 10-14 - but electricity rates keep rising and hardware is the cheapest it has ever been. The deciding factor is North Dakota's export compensation, covered in the net metering section.

Getting Mandan quotes
The spread between the highest and lowest bid for the same roof routinely hits 30-50%, because solar quotes carry very different sales overheads. Two or three independent bids collected against the same system size is the single highest-value hour in the whole project.

Common questions
How long do solar panels actually last?
Panels are typically warrantied for 25 years of production and commonly outlive it, losing about 0.5% output per year. Inverters are the component that usually needs replacement - typically once, around year 12-15, at a few thousand dollars.
Is solar still worth it without the federal credit?
It depends mostly on your state's export rules and your daytime usage. Paybacks lengthened by roughly a third when the credit ended, but rising electricity rates and record-cheap hardware keep the math workable in states with decent export compensation - and marginal where exports pay avoided cost only.
Does solar raise my property taxes?
It depends on the state - many exempt solar's added home value from property tax, others do not, and some exemptions have expiration dates. This guide's state page lists the verified rule and source for your state.
How much does home solar cost in 2026?
The U.S. marketplace average is about $2.58 per watt installed - roughly $15,500 for a 6 kW system and $31,000 for 12 kW, before any state incentives. Quotes meaningfully above that level deserve a written explanation of what justifies the premium.
What happens if my installer goes out of business?
Panel and inverter warranties come from the manufacturers and survive, but the workmanship warranty usually dies with the company. That is a real risk in the post-credit shakeout - prefer installers with years of local history, and get manufacturer-backed workmanship coverage where offered.
