The Federal Tax Credit for Solar

The ITC, or the federal income tax credit for solar, is calculated to cover 30% of your installation cost. This amount is uncapped, and is a pure credit. There are no requirements or restrictions in qualifying for this credit. It applies to all grid-tied solar electric systems.  You fill out the appropriate form on your federal tax return, and you’ll get your money as a refund. If you do not owe enough taxes to cover the full tax refund amount, you can roll over your credit to the following year and for the next 5 years.
