Incentives for Rooftop Solar

What incentives are available for rooftop solar?

Federal and local incentives can have a big impact on the cost of going solar. Below, we cover a few of the most commonly available incentives.In some cases, you may qualify for additional financing options, grants, or rebates based on local and state policies.

Federal solar investment tax credit (ITC)

This tax credit provides a credit off the total cost of your solar installation. You still have to pay up front for the system, but you will receive a credit when you file your taxes. This tax credit only applies to federal income tax. The tax credit is not refundable, meaning that you can’t receive more money back than you paid. However, if you don’t owe enough in taxes to use the credit when you go solar, the IRS allows you to spread the tax credit out over several years, so you won’t lose out on your refund.

First passed in 2006, the ITC is the most impactful solar policy in U.S. history. It has led to an average of 54% annual growth in solar since it was enacted. It was designed to lower the cost of solar and jumpstart the solar industry. And it worked. Members of Congress from both major political parties voted for the ITC, and it was signed into law by President George W. Bush.

The federal solar investment tax credit (ITC) is available for residential systems through 2034. See below for how the credit declines over time.

  • 30% of system cost for systems placed in service between 2022 and 2032
  • 26% of system cost in 2033
  • 22% of system cost in 2034

State & Local Solar Incentives
