The phrase "solar incentives" covers 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. You may be eligible for several kinds of incentives, such as 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 California and others from the federal government. Some broad categories of solar incentives include:

  • Net Metering: You may be able to sign a net metering agreement with your Willowbrook utility company, that may apply to all or a percentage of the excess electricity that is generated by your solar panels. Your utility company will then subtract this value from your utility bill each month.
  • Rebates: Your solar installer might help you claim a rebate, or partial refund of your purchase, for your solar panels. Counties or states will also sometimes offer limited-time rebates. Any rebates you receive will usually come off the total price before tax credits are calculated.
  • Tax Exemptions: These can come in the form of property tax exemptions, which let you exclude the value added by your solar panels when paying taxes on your house. You could also look for exemptions on sales tax at the time of purchase.
  • Tax Credits: Different from tax deductions, tax credits are dollar-for-dollar reductions in the amount of income tax that you owe the government.
  • Solar Renewable Energy Certificate (SREC): Typically, solar systems that produce over a threshold (normally small) amount of electricity can qualify for SRECs or other performance-based incentives. SRECs and similar incentives are typically offered at the state level. When you receive an SREC, you can sell it to your utility company or another buyer, and generally the money you make is normally considered part of your taxable income.

Federal Solar Incentives

Federal solar incentives are probably the first thing that comes to mind when thinking about solar incentives. It's likely that you've 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 installing solar panels.

The ITC can be applied to solar panels installed after January 1, 2006 on a primary or secondary residence that you own in the United States. Originally, the tax credit was for 30% of the total cost — for panels, labor, accessories and equipment — although the percentage may range from 26-30%, depending on the installation date of your solar system. There is no cap on the claim amount.

To know exactly how much the ITC could save you, talk to your local Willowbrook solar panel installer.

The Inflation Reduction Act, passed in August 2022, expanded and extended the ITC (as well as retitling it the Clean Energy Credit). With the new provisions, solar installation projects started after January 1, 2022 and completed by the end of 2032 can qualify for a 30% tax credit. This credit amount will then decrease slightly each year until the current Clean Energy Credit expires in 2035. The expansion to the program also makes credits for energy storage systems even easier to claim, starting in 2023.

More information about the new Inflation Reduction Act can be found here. To better understand how the new Clean Energy Credit will apply to you, talk to your local Willowbrook solar installers.

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 California government.

EcoWatch's Willowbrook, CA Solar Incentives FAQs

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

If your solar system was installed after January 1, 2022, you may qualify for the newly increased 30% tax credit under the Inflation Reduction Act. If you had your system installed between 2006 and 2021, you might qualify for a tax credit between 26% and 30%, depending on the date of installation. Talking to the company that installed your solar system, or any local Willowbrook solar installer, can help you understand what incentives you qualify for.

What are some environmental benefits of adding solar panels to my home?

Solar energy is a renewable energy source — by switching where you get your energy, you help lessen the strain on our planet's resources. Solar panels can also lower your home's CO2 emissions by 250 pounds annually, or roughly 5,000 pounds over 20 years.

I want to trade in my old appliances for ones that are more energy-efficient. Are there any incentives I can apply for?

With the passage of the new Inflation Reduction Act, there are a number of new financial incentives that are available when you make eco-friendly improvements to your home. More details about these incentives, including information about incentives for purchasing new appliances, can be found here.

Can I receive incentives both towards the up-front cost of solar panels, and later as reimbursement?

The order your incentives will be applied in may vary depending on which incentives you are claiming but in most cases yes, you can claim multiple types of incentives for your solar project. Talk with your solar installer or a local tax professional to verify you are claiming all possible incentives and applying them in the correct order.

Can I use multiple types of renewable energy to power my home?

Yes, you can utilize 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 non-renewable backup source of energy. Make sure that you discuss the details of your plan with your local Willowbrook solar panel installer, to make sure you know what you'll need and what incentives you will or won't qualify for.
