What a typical Hartford solar system costs
A 23-panel system (9.2 kW) is about right for an average Hartford home using 10,800 kWh a year. It would produce roughly 11,011 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 3,830 | $6,384 | $1,118 | 5.7 yrs |
| 12 panels | 4.8 kW | 5,745 | $9,576 | $1,677 | 5.7 yrs |
| 16 panels | 6.4 kW | 7,660 | $12,768 | $2,237 | 5.7 yrs |
| 20 panels | 8 kW | 9,574 | $15,960 | $2,796 | 5.7 yrs |
| 26 panels | 10.4 kW | 12,447 | $20,748 | $3,274 | 6.3 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 Hartford gets 1,408 sun hours
That figure comes from Google's analysis of real rooftops across Hartford — 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 Hartford reaches about 1,529 hours, roughly 9% better than typical.
