The term "solar incentives" refers to a wide range of financial incentives implemented to make installing and using solar panels more affordable. This is done to encourage people to switch to renewable energy. The incentives could include upfront discounts, cash back or monthly credits towards your 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. Some broad categories of solar incentives include:

  • Net Metering: Be sure to speak with your Vashon utility company about signing a net metering contract. This allows you to receive credit towards your utility bill every month for the value of excess energy generated by your solar panels. You could receive either a dollar-for-dollar credit or a percentage of the value.
  • Tax Exemptions: These might come in the form of property tax exemptions, which allow you to exclude the value of your solar system when paying property tax on your home. They may also include exemptions on sales tax at the time of purchase.
  • Tax Credits: Tax credits are dollar-for-dollar reductions that lower the amount of income tax you owe the government. (This is different from a tax deduction.)
  • Rebates: A rebate is a partial refund credited to your account after you've paid for your solar panels. Rebates may be offered by your local utility company, your state or your county. The cash back that you get from the rebates is normally applied before calculating tax credits.

Federal Solar Incentives

When someone says "solar incentives," you likely think of federal incentives first. The solar incentive that you may be most familiar with is the Federal Solar Investment Tax Credit (ITC), which provides a credit on your taxes equal to a percentage of the cost of your solar system.

The ITC can be credited towards the value of solar panels installed on your primary or secondary residence in the United States. The solar panels have to have been installed after January 1, 2006, on a property owned by you for you to be eligible for the credit. Originally, the ITC covered 30% of all installation costs (panels, labor, equipment and accessories), although the total amount has fluctuated over time between 26-30%. The amount you qualify for will depend 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 Vashon solar panel installation expert to get more information.

The ITC was both renewed and expanded by the passage of the Inflation Reduction Act in August 2022. It's also now called the Clean Energy Credit. The Clean Energy Credit runs until 2035. Any solar installation project that is completed between January 1, 2022, and December 31, 2032, may qualify for a 30% tax credit; this amount will then decrease slightly on a yearly basis until the end of the current program. 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. Your local Vashon solar panel installer can answer your questions and explain how the new Clean Energy Credit will apply to you.

State & Local Solar Incentives

There are more than just federal solar incentives; tax credits, rebates and more are often offered at the local or state level. Some incentives are ongoing, while others are offered for only a limited time. Your local incentives may come from the Washington government, or from your specific county or municipality.
