Solar panels in Ardmore, OK

Roofs in Ardmore get about 1,724 hours of usable sunlight a year — more than 71% 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.

Check your specific roof in Ardmore → City averages are a starting point; your own roof's size, pitch and shading change the answer a lot.

What a typical Ardmore solar system costs

A 19-panel system (7.6 kW) is about right for an average Ardmore home using 10,800 kWh a year. It would produce roughly 11,137 kWh annually and offset 100% of that usage.

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 Ardmore gets 1,724 sun hours

That figure comes from Google's analysis of real rooftops across Ardmore — 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 Ardmore reaches about 1,781 hours, roughly 3% better than typical.

When Ardmore actually produces

Annual totals hide the thing that catches people out: 34% of Ardmore's yearly sunlight arrives in May–July, and just 15% across November–January.

Output is unusually steady — only about 2.4× between Jun and Dec. Ardmore is close enough to the equator that seasonal variation is mild, which makes sizing a system considerably more predictable.

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

How Ardmore compares to the other 673 cities

What actually stands out about Ardmore:

• Roof space is the binding constraint. A typical Ardmore roof fits about 14 panels and a typical home needs 19 — so there is little room to oversize. If you add an EV or heat pump later, plan the array for it now.
• Small roofs. The median Ardmore roof is 98 m², smaller than 95% of cities measured — worth checking your own footprint before assuming a standard system fits.
• Cheap electricity is the headwind. Oklahoma power costs about 12.1¢/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 Ardmore's 1,724 usable sun hours from other states and provinces. Same sunlight, different electricity prices — which is usually what decides whether solar is worth it.
