A real cost breakdown for a typical 6kW system in North Dakota, not just a national $/watt figure.
North Dakota has one of the lower electricity rates in the country at approximately $0.11/kWh, and a solid, average solar resource at 4.6 peak sun hours a day. Combined with a regional installed-cost estimate of $2.80/watt, a standard 6kW residential system runs approximately $14,630 before any incentives.
| Line item | Estimated cost | Share of total |
|---|---|---|
| Equipment (panels, inverter, racking) | $9,240 | 63% |
| Labor / installation | $5,040 | 34% |
| Permitting & inspection | $350 | 2% |
| Total (before incentives) | $14,630 | 100% |
A 6kW system in North Dakota costs 16% less than the average across the 25 states we track ($17,372), and the electricity rate it offsets is 32% lower than the 0.16 USD/kWh average across those same states. That combination is what actually determines whether North Dakota is a faster- or slower-than-average place to go solar — a lower system cost alone doesn't help if the rate you're offsetting is also low, and vice versa.

At $887 in estimated annual value from 8,059 kWh of yearly production, this system pays back in roughly 17 years — a longer payback period than the national average. North Dakota: Statewide net metering at retail rate. On incentives specifically: North Dakota has no state solar tax credit; net metering at retail rate is the primary ongoing benefit. The federal residential tax credit (Section 25D) expired for owned systems after December 31, 2025 — see our 2026 tax credit guide for what that means for your net price.
A typical 6kW residential solar system in North Dakota costs approximately $14,630 installed in 2026, based on a regional estimate of $2.44/watt — equipment usually makes up about 55% of that, labor about 30%, with the rest in permitting.
