Federal Tax Credits, Residential:

Small Wind Tubines:

A wind turbine collects kinetic energy from the wind and converts it to electricity that is compatible with a home's electrical system.

Requirements: Must have a nameplate capacity of no more than 100 kilowatts.Tax Credit includes installation costs.

Tax Credit: 30% of cost with no upper limit
Expires: December 31, 2016
Details: Existing homes & new construction qualify. Both principal residences and second homes qualify. Rentals do not qualify

Solar Panels (Photovoltaic Systems):

Solar Panels or Photovoltaic Systems are solar cells that capture light energy from the sun and convert it directly into electricity.

Requirements: Photovoltaic systems must provide electricity for the residence, and must meet applicable fire and electrical code requirement.

Tax Credit: 30% of cost with no upper limit
Expires: December 31, 2016
Details: Existing homes & new construction qualify. Both principal residences and second homes qualify. Rentals do not qualify

Solar Water Heaters:

Solar water heaters come in a wide variety of designs, all including a collector and storage tank, and all using the sun's thermal energy to heat water. Solar water heaters are typically described according to the type of collector and the circulation system.

Requirements: At least half of the energy generated by the "qualifying property" must come from the sun. The system must be certified by the Solar Rating and Certification Corporation (SRCC) or a comparable entity endorsed by the government of the state in which the property is installed.

Tax Credit includes installation costs.

Tax Credit: 30% of cost with no upper limit
Expires: December 31, 2016
Details: Existing homes & new construction qualify. Both principal residences and second homes qualify. Rentals do not qualify

Geothermal Heat Pumps:

Geothermal heat pumps are similar to ordinary heat pumps, but use the ground instead of outside air to provide heating, air conditioning and, in most cases, hot water. Because they use the earth's natural heat, they are among the most efficient and comfortable heating and cooling technologies currently available.

Tax Credit includes installation costs.

Tax Credit: 30% of cost with no upper limit
Expires: December 31, 2016
Details: Existing homes & new construction qualify. Both principal residences and second homes qualify. Rentals do not qualify
