Solar incentives are designed to make renewable energy usage more affordable via financial incentives for individuals who install solar panels on their homes. You might qualify for several types of incentives, including cash back, discounts or credit towards your monthly utility bill, depending on your situation. Certain incentives come from your specific utility company, county or municipality, some from the Arizona government and others from the federal government. Some broad categories of solar incentives include:

  • Net Metering: Net metering factors in after your solar panels are up and running. If you've signed a net metering agreement with your Williamson utility company, they will subtract the value of the excess energy your solar system produces from your monthly utility bill. In some places, this is a dollar-for-dollar credit, while in other areas you may be refunded a percentage of the value.
  • Tax Credits: Unlike tax deductions, tax credits reduce, dollar-for-dollar, the amount of income tax that you owe the federal government.
  • Tax Exemptions: These might come in the form of property tax exemptions, which let you exclude the value of your solar system when calculating the taxes you pay on your home. They may also include exemptions on sales tax at the time of purchase.
  • Rebates: A rebate is a partial refund given after you've purchased your solar panels. Rebates might be offered by your local utility company, your state or your county. The rebates are usually applied before calculating tax credits.

Federal Solar Incentives

Federal incentives are the kind of incentives that you are most likely to have heard of. You've likely heard of the Federal Solar Investment Tax Credit, or ITC. This incentive is a tax credit that reduces your taxes by a certain percentage of the money you spend on solar panels for your home.

The ITC can be applied to the total cost of installing solar panels, including the panels themselves as well as labor, equipment and accessories. This credit can be claimed for panels installed after January 1, 2006 on a primary or secondary residence that you own, as long as it is located in the United States. Originally set at 30% of total costs, the credit has fluctuated over time, and you may qualify for different amounts depending on when your project was completed. There is no maximum amount you can claim.

To best understand how the ITC might apply to you, get in touch with your local Williamson solar panel installer and request more information.

In August 2022, the ITC (now referred to as the Clean Energy Credit) was bolstered by the passing of the Inflation Reduction Act. The new Clean Energy Credit now runs until 2035. You can now apply for a 30% credit for solar systems installed between January 1, 2022 and December 31, 2032. This credit will then see a slight annual decrease until it expires. Starting in 2023, the expansion to the program will also make it easier to get credit for energy storage systems.

State & Local Solar Incentives

Federal solar incentives are not your only option; tax credits, rebates and more may be offered at the local or state level. Incentives may be provided by your county or municipality, or by the state of Arizona. Certain incentives might only be available for a limited time, while others are ongoing.
