How Connecticut compares to the rest of the US
Two numbers drive solar economics: your electricity rate and how much sun your roof gets. Here's where Connecticut stands against the national average.
| Electricity rate | $0.30/kWh (80% higher than the $0.17 US avg) |
| Daily peak sun hours | 3.9 (13% less than the 4.5 US avg) |
| Net metering | Broadly available |
Connecticut has above-average electricity prices but below-average sun. The high rates are exactly what make solar pay off here — every kWh you generate offsets expensive grid power, even if your panels produce a little less than they would in a sunnier state.
