What a typical Ann Arbor solar system costs
A 23-panel system (9.2 kW) is about right for an average Ann Arbor home using 10,800 kWh a year. It would produce roughly 10,964 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 3,813 | $6,384 | $728 | 8.8 yrs |
| 12 panels | 4.8 kW | 5,720 | $9,576 | $1,093 | 8.8 yrs |
| 16 panels | 6.4 kW | 7,627 | $12,768 | $1,457 | 8.8 yrs |
| 20 panels | 8 kW | 9,534 | $15,960 | $1,821 | 8.8 yrs |
| 26 panels | 10.4 kW | 12,394 | $20,748 | $2,139 | 9.7 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 Ann Arbor gets 1,402 sun hours
That figure comes from Google's analysis of real rooftops across Ann Arbor — 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 Ann Arbor reaches about 1,500 hours, roughly 7% better than typical.
