What a typical New Bedford solar system costs
A 25-panel system (10 kW) is about right for an average New Bedford home using 10,800 kWh a year. It would produce roughly 11,178 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 3,577 | $6,384 | $1,077 | 5.9 yrs |
| 12 panels | 4.8 kW | 5,365 | $9,576 | $1,615 | 5.9 yrs |
| 16 panels | 6.4 kW | 7,154 | $12,768 | $2,153 | 5.9 yrs |
| 20 panels | 8 kW | 8,942 | $15,960 | $2,692 | 5.9 yrs |
| 26 panels | 10.4 kW | 11,625 | $20,748 | $3,313 | 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 New Bedford gets 1,315 sun hours
That figure comes from Google's analysis of real rooftops across New Bedford — 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 New Bedford reaches about 1,596 hours, roughly 21% better than typical.
