Connecticut’s residential electricity rates are some of the highest in the country.1 Still, taking control over electric bills isn’t the only reason why Connecticut residents are switching to solar. By installing a new photovoltaic (PV) system, you can also get outage protection and reduce your carbon emissions while enjoying the state’s excellent solar incentives.

Sunrun is the country’s leading residential solar and storage company.4 We work to ensure you can gain energy independence and make the most out of Connecticut’s solar tax credit, tax incentives, and rebate programs.
