The term "solar incentives" generally refers to financial incentives put in place by solar companies and the government to encourage increased use of renewable energy by making installing and using solar panels more affordable. Incentives could include things like discounts, cash back or credit towards your monthly utility bill. Some incentives are offered federally, while others are offered by the state of New York or your utility company, county or municipality. Categories of solar incentives include:

  • Net Metering: You may be able to sign a net metering agreement with your Washington utility company, that may apply to all or a percentage of the excess electricity your solar panels generate. Your utility company will then subtract this value from your monthly utility bill.
  • Rebates: A solar rebate is a partial refund given after you've purchased your solar system. Rebates could be offered by your local utility company, your state or your county. The rebates are usually applied before calculating tax credits.
  • Tax Credits: Tax credits are dollar-for-dollar reductions in the amount of income tax that you owe the government. (This is different from a tax deduction.)
  • Tax Exemptions: Tax exemptions can come in one of two forms. The first is sales tax exemption, applied at the time you purchase your solar panels. The second is property tax exemption, which allows you to exclude the added value of your solar system when paying property tax on your home.

Federal Solar Incentives

When thinking about solar incentives, federal incentives may be the first thing that comes to mind. The Federal Solar Investment Tax Credit, or ITC, is likely the most well-known federal solar incentive. The ITC provides you with a tax credit for a set percentage of the cost of your solar system.

The ITC can be applied to the total cost of solar panel installation, including the panels themselves as well as accessories, labor and equipment. You can claim this credit for panels installed after January 1, 2006 on a primary or secondary residence that you own and that 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 claim amount.

To better understand exactly how much money the ITC could save you, talk to your local Washington solar panel installer.

In August 2022, the ITC (now called the Clean Energy Credit) was expanded and extended by the passing of the Inflation Reduction Act. The new Clean Energy Credit now runs until 2035. American homeowners can now apply for a 30% credit for solar systems that began installation on or after January 1, 2022 and will be done by December 31, 2032. This credit will then be decreased by a few percentage points every year until the date of expiration. Starting in 2023, it will also be easier to get credits for energy storage systems with the new act.

State & Local Solar Incentives

In addition to federal solar incentives, there are often also state ones. Tax credits, rebates and more might be available at a more local level. Certain incentives are ongoing, while others are offered for only a limited time. Your local solar incentives might come from your county or municipality, or from the New York government.

Next Steps for Installing Solar in Washington

Solar energy use nationwide has increased enormously in the past 15 years, in part due to the increase in availability of solar incentives. You might receive these incentives from the New York government, the federal government or your local utility company. Talking to your local Washington solar panel installer is a great first step towards getting all the incentives you qualify for when you switch to solar energy.
