The phrase "solar incentives" refers to a range of financial incentives designed to make installing and using solar panels more affordable. This is done to encourage people to switch to renewable energy. These incentives can include upfront discounts, cash back or credit towards your monthly utility bill. Some incentives are provided by the federal government, some by the Washington government and some by your specific utility company, county or municipality. Types of solar incentives might include:

  • Rebates: Solar rebates might be provided by your local utility company, or by your county or state. These rebates are essentially partial refunds that are applied after your purchase of solar panels and before tax credits are calculated.
  • Tax Exemptions: These might come in the form of property tax exemptions, which let you ignore the value added by your solar panels when paying taxes on your home. You may also qualify for an exemption on sales tax at the time of purchase.
  • Tax Credits: Tax credits are dollar-for-dollar reductions (not deductions) in the amount of tax that you owe the federal government.
  • Net Metering: Net metering becomes relevant once your solar system is up and running. If you have in place a net metering agreement with your Mill Creek utility company, the company will subtract the value of the excess energy your solar system produces from your monthly utility bill. In some areas, this credit is dollar-for-dollar, while in other places you may receive a refund equivalent to a percentage of the value.

Federal Solar Incentives

When thinking about solar incentives, you likely think of federal incentives first. You may have heard of the Federal Solar Investment Tax Credit, or ITC. This is a tax credit that reduces your taxes by a certain percentage of the money you spend on your solar system.

The ITC can be applied to a solar system installed on your primary or secondary residence in the United States. The solar system must have been installed after January 1, 2006, on a property you own for you to claim the credit. The ITC initially covered 30% of all installation costs (panels, accessories, equipment and labor), although the total amount has fluctuated over time between 26-30%. The installation date of your solar system will determine what percentage you are eligible for. There is no cap on the claim amount.

Curious how the ITC might apply to your specific situation? Get in touch with your local Mill Creek solar panel installation expert to get more information.

In August 2022, the Inflation Reduction Act made revisions to the ITC, now titled the Clean Energy Credit. Homeowners are now eligible for a credit equal to 30% of the total solar system installation costs for projects that began after January 1, 2022, and will be finished by the end of 2032. The credit percentage will then begin to decrease annually until the Clean Energy Credit expires in 2035. The program expansion also makes claiming credit for energy storage systems easier than ever before, starting in 2023.

State & Local Solar Incentives

Some solar incentives are often also offered at the local or state level. Like with federal incentives, these may include rebates, tax credits and more. These incentives — which might be provided by your county or municipality, or by the state of Washington — may be offered on an ongoing basis, or for only a limited time.

How long until the federal solar tax credit ends?
