Federal and State Tax Credits and Rebates for Residential Renewable Energy Installations

There is a 30% Federal Tax Credit with no upper $ limit available until 2016 for the following in principal and second homes, in both new construction and remodeling (no rentals):

  • Solar hot water heaters. Typical systems provide 70% of a home’s hot water. Pool heating systems are not eligible. Grants from the CT Clean Energy Finance and Investment Authority can pay on average 30% of a system’s cost.
  • Solar electric (photovoltaic) systems up to 10 kW. Roof should be in good shape and not obstructed by trees. State CEFIA grants available up to $12,250 for systems up to 5 kW and up to $18,500 for systems up to 10kW. Systems can be leased instead of purchased, with monthly costs lower than existing electric bills.
  • Geothermal heat pumps use loops of piping carrying an antifreeze solution buried underground or in bodies of water to both heat and cool homes. Highly efficient, they can also provide domestic hot water.
  • Small wind turbines
    (under 100 kW)
  • Residential fuel cells at least 30% efficient and with a capacity of at least 0.5 kW.

State rebate programs are also available for non-residential installations.

Connecticut law exempts residential renewable energy systems from both property and sales taxes.
