Solar panels in Norman, OK
Roofs in Norman get about 1,781 hours of usable sunlight a year — more than 79% 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 Norman → City averages are a starting point; your own roof's size, pitch and shading change the answer a lot.
What a typical Norman solar system costs
A 18-panel system (7.2 kW) is about right for an average Norman home using 10,800 kWh a year. It would produce roughly 10,900 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 4,844 | $6,384 | $586 | 10.9 yrs |
| 12 panels | 4.8 kW | 7,266 | $9,576 | $879 | 10.9 yrs |
| 16 panels | 6.4 kW | 9,689 | $12,768 | $1,172 | 10.9 yrs |
| 20 panels | 8 kW | 12,111 | $15,960 | $1,346 | 11.9 yrs |
| 26 panels | 10.4 kW | 15,744 | $20,748 | $1,456 | 14.2 yrs |
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 Norman gets 1,781 sun hours
That figure comes from Google's analysis of real rooftops across Norman — 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 Norman reaches about 1,813 hours, roughly 2% better than typical.
