The Solar Investment Tax Credit (ITC) is a federal tax credit in the United States that incentivizes homeowners and businesses to install solar energy systems on their properties. The ITC allows for a credit of up to 26% of the total cost of a solar system installation.

The good news is that there is no limit to how many times you can claim the solar tax credit. However, there are some restrictions and caveats to keep in mind.

First, the solar tax credit is a one-time credit per solar installation. In other words, if you install multiple solar systems on different properties, you can claim the credit for each one. But if you install multiple solar systems on the same property, you can only claim the credit once.

Additionally, the solar tax credit is a non-refundable credit, meaning that it can only be used to offset your tax liability for the year in which it is claimed. If your tax liability is less than the credit amount, you can carry over the remaining credit to future tax years for up to five years.

It’s also worth noting that the solar tax credit will begin to phase out after 2021. For solar systems installed in 2022, the credit will drop to 22%, and it will drop to 0% for residential systems and 10% for commercial systems installed after 2023.
