Solar panels in Fort Wayne, IN

Roofs in Fort Wayne get about 1,468 hours of usable sunlight a year — less than 55% 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 Fort Wayne solar system costs

A 22-panel system (8.8 kW) is about right for an average Fort Wayne home using 10,800 kWh a year. It would produce roughly 10,981 kWh annually and offset 100% of that usage.

How we worked this out for Fort Wayne

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

Step 6 matters more than it looks. Only 34% of what a system this size produces in Fort Wayne is used the moment it is generated; the other 7,201 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 — 10.4 years against the 10.6 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, 15.3¢/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 Fort Wayne gets 1,468 sun hours

That figure comes from Google's analysis of real rooftops across Fort Wayne — 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 Fort Wayne reaches about 1,555 hours, roughly 6% better than typical.

When Fort Wayne actually produces

Annual totals hide the thing that catches people out: 36% of Fort Wayne's yearly sunlight arrives in May–July, and just 13% across November–January.

Fort Wayne produces about 3.2× as much in Jun as in Dec — a normal mid-latitude swing. Expect real winter shortfall and summer surplus rather than steady year-round output.

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

How Fort Wayne compares to the other 788 cities

What actually stands out about Fort Wayne:

• Plenty of roof to work with. Typical roofs here fit around 91 panels — roughly 4× what an average home needs. Roof size will not be what limits your system in Fort Wayne.
• Every kWh counts more here. The grid serving Fort Wayne emits 883 kg CO₂ per MWh, among the highest of the 788 cities measured — so the same panels displace more emissions than they would elsewhere.
