Transitioning to solar power can help homeowners save loads of money, especially in the long run. Over time, monthly savings on utility bills really add up, making solar panels a financially savvy investment. In the short term, though, the initial price can be pretty steep.

Thankfully, there are a number of tax incentives available to help you offset the starting cost of solar panels — and to provide additional monetary benefits down the road. The most notable of these incentives is the federal solar tax credit, which defrays 26% of the total startup installation cost. What's more, many states offer their own benefits to homeowners who wish to invest in solar power, and many of those benefits are quite significant.

So, what are the top states for solar tax incentives? Let's dive in.

Federal Tax Incentives for Solar Energy

No matter which state you live in, all American homeowners can claim a federal tax incentive for installing solar panels. This credit can be claimed on your federal income tax return and is worth 26% of the total cost of your solar purchase. The incentive is meant to make solar installations more affordable and more accessible to a wider range of homeowners.

The Solar Investment Tax Credit (ITC) was first developed through the Energy Policy Act of 2005. Initially, it was set to last for just two years, but it has been extended for residential solar installations through at least 2023. (Note that the specific terms of the credit have changed over the years and may continue to shift.)

To be eligible for the federal credit, homeowners must meet the following criteria:

  • You have installed a residential solar system at any point from 2006 through the end of 2022.
  • You have placed the solar system in a residential location. It does not have to be your primary residence.
  • You own the solar system (as opposed to leasing it), meaning you paid for it in cash or are financing it.

Is Home Solar Right for You?

We've noted some of the top states for solar tax incentives, but it's worth noting that there are plenty of other states that offer net metering, rebates and other financial incentives. Additionally, we recommend checking for financial incentives from your city/municipality or your local utility company.

While solar installation can cost a lot of money on the front end, these incentives can make it worthwhile — especially if you live somewhere with ample sun exposure, where you can really take advantage of your system's energy-producing abilities.
