The Energy Policy Act of 2008 establishes a flat 30% tax credit for the purchase and installation of residential photovoltaic (solar electric) and solar water heating property. An individual can take BOTH a 30% credit for a photovoltaic system and a 30% credit for a solar water heating system. See DSIRE for more information or contact us.
