Connecticut's solar advantage is simple: Some of the highest electricity rates in the nation (23¢/kWh average) make solar compelling despite limited sun hours. Eversource territory dominates the state with good net metering policies.

For Hartford and New Haven area homeowners, solar delivers strong returns thanks to high electric rates. The state's renewable energy rebates help offset higher install costs in the Northeast.
