Solar panels in Fargo, ND

Roofs in Fargo get about 1,504 hours of usable sunlight a year — more than 50% of the cities we've measured. Here's what that means in cost, savings and payback, using real rooftop data rather than a national average.

What a typical Fargo solar system costs

A 22-panel system (8.8 kW) is about right for an average Fargo home using 10,800 kWh a year. It would produce roughly 11,250 kWh annually and offset 100% of that usage.

How we worked this out for Fargo

Every number on this page comes from these seven steps. Nothing is a national average — the sunlight figure is measured from Fargo rooftops.

Step 6 matters more than it looks. Only 34% of what a system this size produces in Fargo is used the moment it is generated; the other 7,470 kWh is exported and credited one-for-one under net metering. Because exports here are credited at or near retail, that split changes the payback very little — 14.1 years against the 14.5 we show. In places where exports pay a fraction of retail the same split moves payback by years, which is why we model it explicitly rather than assuming.

Assumptions: 400W panels, 15% system losses (inverter, wiring, heat, soiling), $2.85/W installed, 10,800 kWh typical annual household use, 11.1¢/kWh electricity. Change any of those and every figure above moves — which is exactly why a single national "solar costs X" number is misleading.

Notice that payback barely improves as systems get bigger, and eventually gets worse. That's because you can only save money on electricity you were going to buy anyway. Once a system covers your usage, extra panels mostly generate exports at a much lower rate.

Why Fargo gets 1,504 sun hours

That figure comes from Google's analysis of real rooftops across Fargo — it already accounts for shading from trees, chimneys and neighbouring buildings, which is why it's lower than the raw "hours of daylight" figures you'll see elsewhere. An unusually open, unshaded roof in Fargo reaches about 1,608 hours, roughly 7% better than typical.

When Fargo actually produces

Annual totals hide the thing that catches people out: 39% of Fargo's yearly sunlight arrives in May–July, and just 11% across November–January.

That is a severe seasonal swing — Fargo produces roughly 4.4× as much in Jun as in Dec. A system sized to cover your annual usage will overproduce badly in summer and fall well short in winter, so how your utility credits exported power matters more here than in most places.

The annual total is measured from Google's rooftop imagery. Its split across months is calculated from solar geometry at Fargo's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.

How Fargo compares to the other 788 cities

What actually stands out about Fargo:

• Plenty of roof to work with. Typical roofs here fit around 108 panels — roughly 4× what an average home needs. Roof size will not be what limits your system in Fargo.
• Every kWh counts more here. The grid serving Fargo emits 832 kg CO₂ per MWh, among the highest of the 788 cities measured — so the same panels displace more emissions than they would elsewhere.
• Cheap electricity is the headwind. North Dakota power costs about 11.1¢/kWh. Low rates are good news generally, but they lengthen solar payback — there is simply less bill to displace.

Cities with almost the same sunlight

These are the closest matches to Fargo's 1,504 usable sun hours from other states and provinces. Same sunlight, different electricity prices — which is usually what decides whether solar is worth it.
