Solar Investment Tax Credit

The solar Investment Tax Credit (ITC) is one of the most important federal policy mechanisms to support the growth of solar energy in the United States. Since the ITC was enacted in 2006, the U.S. solar industry has grown by more than 10,000%. In 2015, SEIA successfully advocated for a multi-year extension of the credit, which has provided critical stability for businesses and investors.

Quick Facts about the ITC
