In December 2015, the generous federal tax credit for solar energy were renewed by wide margins in the US House and Senate. The extended credit program will continue to provide 30% of the value of an installed solar system as a credit against tax owed for both homeowners and businesses. The credit applies to solar electric or solar water heating systems installed on single-family or multifamily dwellings. The credit applies to taxes owed, so in order to take the credit, a home or business owner must pay income tax through direct or indirect means.
Note that a tax credit is different than a deduction and has a 100% cash value for offsetting taxes to be paid. Normally the credit is realized by an increase in the amount of IRS refund in the year it is taken.
