The term "solar incentives" refers broadly to financial incentives designed to encourage the use of renewable energy by making solar panels more affordable. Incentives can include things like discounts, cash back or credit towards your monthly utility bill. Some incentives are handled federally, while others are provided by the state of Utah or your specific utility company, county or municipality. Some broad categories of solar incentives include:

  • Net Metering: Net metering factors in once your solar panels are up and running. If you have in place a net metering agreement with your Washington utility company, it will subtract the value of the excess energy your solar system produces from your utility bill each month. In some places, this credit is dollar-for-dollar, while in others you might receive a refund equivalent to a percentage of the value.
  • Rebates: Some solar companies will help you claim a rebate, or partial refund after purchase, for your solar panels. Counties or states will also offer limited-time rebates at various times. If you receive a rebate, that amount will usually be deducted from the total price before any tax credits are calculated.
  • Tax Credits: Tax credits are dollar-for-dollar reductions (not deductions) in the amount of tax that you owe the federal government.
  • Tax Exemptions: Sales tax exemptions are applied at the point of sale for your solar panels. Property tax exemptions let you exclude the added value of your solar system when you calculate the amount of property tax you need to pay on your house.

Federal Solar Incentives

When people think of solar incentives, federal incentives might be the first thing that comes to mind. You've likely heard of the Federal Solar Investment Tax Credit, or ITC. The ITC is a tax credit that reduces your taxes by a predetermined percentage of the money you spend on solar panels for your home.

The ITC can be applied to solar systems installed after January 1, 2006, on a primary or secondary residence that you own in the United States. The credit initially covered 30% of the total cost – for panels, accessories, labor and equipment – although the percentage may range from 26-30%, depending on when your solar system was installed. There is no cap on the amount you can claim.

Curious how the ITC might apply to your specific situation? Reach out to your local Washington solar panel installation expert to get more information.

In August 2022, the ITC (now referred to as the Clean Energy Credit) was expanded and extended by the passage of the Inflation Reduction Act. For solar systems installed between January 1, 2022, and December 31, 2032, homeowners may be eligible for a credit for 30% of the total cost. The percentage will then decrease annually until the Clean Energy Credit ends in 2035. The expansion also makes it easier to get credit for energy storage systems, beginning in 2023.

More information about the new Inflation Reduction Act can be found here. The easiest way to fully understand how the new Clean Energy Credit might apply to you is to reach out to your local Washington solar panel installation expert with your questions.

State & Local Solar Incentives

There are often state solar incentives available in addition to federal ones. Rebates, tax credits and more can be offered at a more local level. Certain incentives are offered for only a limited time, while others are ongoing. These local incentives may come from your county or municipality, or from the Utah government.

Next Steps for Installing Solar in Washington

You can apply for and receive solar incentives from the Utah government and the federal government, as well as from your local utility company. Growing availability of solar initiatives over the last 15 years has helped increase solar adoption nationwide. Contact your local solar panel installer today to find out more information and to save the most money possible on solar panels for your Washington home.
