Solar incentives are intended to encourage people to make the switch to renewable energy by providing financial incentives that lower the burden of solar panel installation and use. Incentives could include things like discounts, cash back or credit on your utility bill each month. Some incentives are offered federally, while others are offered by the state of Washington or your utility company, county or municipality. Categories of solar incentives include:

  • Tax Credits: Tax credits are dollar-for-dollar reductions that lower the amount of income tax you owe the government. (A tax credit is different from a tax deduction.)
  • Net Metering: Net metering factors in after your solar system is up and running. If you've signed a net metering agreement with your DuPont utility company, it will subtract the value of the excess energy your solar system produces from your monthly utility bill. In some locations, this credit is dollar-for-dollar, while in other areas you may receive a refund equivalent to a percentage of the value.
  • Rebates: A rebate is a partial refund after the purchase of your solar panels. These might be offered by your local utility company, your county or your state. The cash back that you get from the rebates is normally applied before calculating tax credits.
  • Tax Exemptions: Sales tax exemptions are applied at the time of purchase for your solar system. Property tax exemptions allow you to exclude the added value of your solar system when calculating the amount of property tax you need to pay on your home.

Federal Solar Incentives

Federal incentives are the kind of incentives that you are most likely to have heard of. The solar incentive that you may be most familiar with is the Federal Solar Investment Tax Credit (ITC), which gives you a credit on your taxes equal to a predetermined percentage of your solar system's cost.

The ITC can be applied to solar systems installed after January 1, 2006, and allows you to deduct from your taxes a percentage of the total cost of solar panels, equipment, accessories and labor. You can receive this credit for a solar panel system installed on a primary or secondary residence in the United States that you own. Originally, you could claim 30% of the total cost, although certain projects may qualify for only 26%, depending on the details. There is no maximum amount you can claim.

Contacting your local DuPont solar panel installer is the best way to learn more about how the ITC may apply to you.

In August 2022, the Inflation Reduction Act made revisions to the ITC, now titled the Clean Energy Credit. The Clean Energy Credit runs until 2035. Solar installation projects started after January 1, 2022, and completed by the end of 2032 may qualify for a 30% tax credit; the amount will decrease slightly on a yearly basis until the current program ends. Starting in 2023, it will also be easier to qualify for credits for energy storage systems with the new act.

More information about the new Inflation Reduction Act can be found here. Your local DuPont solar panel company can answer any questions you have and explain how the new Clean Energy Credit applies to you.

State & Local Solar Incentives

Some solar incentives are often also provided at the state and local level. Similar to federal incentives, these could include tax credits, rebates and more. Incentives might be provided by the state of Washington, or by your county or municipality. Certain incentives are available for only a limited time, while others are ongoing.

Next Steps for Installing Solar in DuPont

You can apply for and receive solar incentives from the federal government and the Washington government, as well as from your local utility company. This increase in availability of solar initiatives in the past 15 years has helped increase solar adoption nationwide. Your local DuPont solar panel installation expert can help you learn more about which incentives you might qualify for, and get you started on the path to switching to renewable energy today.

EcoWatch's DuPont, WA Solar Incentives FAQs

How do I know if I qualify for certain solar incentives?

Generally, solar incentives apply to:

  1. a new solar system
  2. installed on a property that you own
  3. within the U.S.
  4. between the dates specified by a particular incentive.

Specific incentives, including those given out by the Washington government or by your county/municipality, may have additional qualifications. Get in touch with your local DuPont solar installer to discover what incentives your project will qualify for.

If my house already has solar panels, can I still claim incentives?

You should plan to talk to a representative from the company that installed your solar panels – or speak to a local DuPont solar installer — to clarify which incentives you may qualify for. If your system was installed after January 1, 2022, you likely qualify for the recently increased 30% tax credit under the Inflation Reduction Act. Solar systems installed between 2006 and 2021 may qualify for a tax credit of 26-30%.

What are some of the environmental benefits of switching to solar?

You can lower your carbon footprint by 50 pounds of CO2 annually by switching to solar panels. This adds up to roughly 1,000 pounds over 20 years. In addition, solar power is a renewable energy source, meaning that switching your home over lessens the drain on our planet's resources.

When does the federal solar tax credit end?

The federal solar tax credit, previously called the ITC and now named the Clean Energy Credit, is set to end January 1, 2035. The current 30% credit will end in 2032, replaced by a 26% credit in 2033 and a 22% credit in 2034.

Can I use a combination of solar and another type of renewable energy to power my home?

Yes, you can use multiple types of renewable energy to power your home, such as a combination of solar and wind power. You can also use both renewable energy sources and a backup source of non-renewable energy. You should discuss the details of your plan with your local DuPont solar installation expert, to make sure you know what you'll need and what incentives you might or might not qualify for.
