Solar Investment Tax Credit (ITC)


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% - creating hundreds of thousands of jobs and investing billions of dollars in the U.S. economy in the process.

SEIA has successfully advocated for multiple extensions of this critical tax credit, including the most recent delay of the credit phasedown in December 2020. SEIA also supports legislation that would extend benefits of the Investment Tax Credit to energy storage. Click here to learn more. Quick facts
