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 - Portal 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 Portal homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
If a salesperson in Portal 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.
Leased and PPA systems deserve extra scrutiny in 2026: the sales pitch often bundles 'tax savings' that now accrue to the leasing company under separate commercial rules - not to you. Get every claimed saving in writing, attributed to a specific law, before signing a 20-25 year contract.

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 Portal roofs
Beware of any 2026 payback estimate that looks as good as the 2025 ones: with the federal credit gone, a third of the old subsidy math vanished. If a sales projection has not gotten noticeably worse since 2025, it is hiding something - usually an inflated utility-rate escalation assumption.

Getting Portal quotes
Same-day contracts are a red flag in this industry. Legitimate ND installers expect you to compare bids, check licenses, and read the interconnection terms. Anyone pressuring you to sign at the kitchen table is pricing in your haste.

Common questions
Should I lease, get a PPA, or buy?
Buying keeps all savings and any incentives with you. Leases and PPAs put a company's equipment on your roof for 20-25 years, complicate a home sale, and in 2026 any tax benefits they advertise belong to the company under commercial rules - not to you. Read escalator clauses carefully.
What is net metering and why does it decide everything?
It is the rule for how your utility credits electricity you export. Full retail net metering credits exports at the same rate you pay - the grid works like a free battery. Net billing or avoided-cost rules pay far less per exported kWh, which lengthens payback and strengthens the case for a home battery.
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.
