Solar incentives encourage people to make the switch to renewable energy by offering financial incentives that lower the burden of solar panel installation and use. You might be eligible for several types of incentives, including cash back, discounts or credit towards your monthly utility bill, depending on your situation. Some incentives come from your specific utility company, county or municipality, some from the state of Washington and others from the federal government. Some broad categories of solar incentives include:

  • Tax Exemptions: Sales tax exemptions go into effect at the time of purchase for your solar system. Property tax exemptions allow you to ignore the value that your solar panels add when you calculate how much property tax you need to pay on your house.
  • Tax Credits: Different from tax deductions, tax credits are dollar-for-dollar reductions in the amount of income tax that you owe the federal government.
  • Rebates: Solar rebates might be offered by your state or county, or by your local utility company. These rebates are essentially partial refunds that are applied after you pay for a solar system and before tax credits are calculated.
  • Net Metering: You can sign a net metering contract with your Longview utility company. This agreement 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 utility bill each month.

Federal Solar Incentives

Federal solar incentives are likely to be the first thing that you think of when thinking about solar incentives. 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 certain percentage of the money you spend installing solar panels.

The ITC can be credited towards the value of a solar system 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 you own for you to claim the credit. The ITC originally paid out 30% of all costs (panels, accessories, labor and equipment), although this 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 amount you can claim.

To better understand exactly how much money the ITC could save you, contact your local Longview solar panel installer.

The Inflation Reduction Act, passed in August 2022, made some changes to the ITC (as well as retitling it 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; this amount will be decreased slightly on a yearly basis until the current program ends. The expansion to the program also makes it easier to get credit for energy storage systems, beginning in 2023.

State & Local Solar Incentives

Rebates, tax credits and more can be claimed at multiple levels. Along with federal solar incentives, there are often state and local ones, too. Incentives might be provided by the state of Washington, or by your county or municipality. Some incentives may be available for only a limited time, while others are ongoing.

Next Steps for Installing Solar in Longview

There are a variety of solar incentives: those offered by local utility companies, those provided by the Washington government and those provided by the federal government, to name a few. The use of solar energy has increased enormously in the last 15 years, partially thanks to these incentives. We recommend talking to your local Longview solar installer to learn more about these incentives and to ensure that you're getting the most money possible for your solar system.
