The term "solar incentives" covers a wide range of financial incentives put in place to make installing and using solar panels more affordable. This is done to encourage people to switch to renewable energy. You might be eligible for different kinds of incentives, including cash back, discounts or monthly utility bill credits, 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. Categories of solar incentives include:

  • Solar Renewable Energy Certificate (SREC): SRECs and other performance-based incentives may be available to you if your solar system produces more than a specified (usually small) amount of electricity. Performance-based incentives are usually handled by the state government. You can sell the SRECs you receive to your utility company or other buyers, and the money you receive in return is generally considered part of your taxable income.
  • Tax Exemptions: These may come in the form of property tax exemptions, which allow you to exclude the value added by your solar panels when calculating the taxes you pay on your house. You may also qualify for an exemption on sales tax at the time of purchase.
  • Net Metering: Net metering factors in once your solar panels are up and running. If you have in place a net metering agreement with your Vacaville utility company, it will subtract the value of the excess energy your solar system produces from your utility bill each month. In some areas, this credit is dollar-for-dollar, while in other places you may get refunded a percentage of the value.
  • Rebates: Some solar companies will help you claim a rebate, or partial refund after purchase, for your solar system. States or counties will also offer limited-time rebates at various times. Any rebates you receive will usually be deducted from the total price before tax credits are calculated.
  • Tax Credits: Unlike tax deductions, tax credits reduce, dollar-for-dollar, the amount of income tax that you owe the federal government.

Federal Solar Incentives

Federal solar incentives are likely to be the first thing that you think of when thinking about solar incentives. The Federal Solar Investment Tax Credit, or ITC, is likely the best-known federal solar incentive. The ITC allows you to claim a tax credit for a predetermined percentage of the cost of your solar system.

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

Your local Vacaville solar panel installer can offer more information about the ITC and how it may apply to your situation.

In August 2022, the Inflation Reduction Act laid out new provisions for the ITC, now titled the Clean Energy Credit. For solar system installations that begin after January 1, 2022 and are completed by the end of 2032, homeowners can apply for a credit equal to 30% of the total cost. The percentage will then decrease annually until the Clean Energy Credit expires in 2035. Beginning in 2023, it will also be easier to obtain credits for energy storage systems under this new program.

More information about the new Inflation Reduction Act can be found here. Your local Vacaville solar panel installation experts can answer any questions you have and explain how the new Clean Energy Credit may apply to you.

State & Local Solar Incentives

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

EcoWatch's Vacaville, CA Solar Incentives FAQs

What if I add solar panels to a rental property, vacation home or commercial property? Will I still qualify for incentives?

Many solar incentives are intended to apply to a property located within the United States that you own; most secondary residences will fall into this category. Other solar incentives may be available for commercial properties, depending on the specifics. We recommend getting in touch with your local solar installer and/or tax professional to better understand what incentives may apply to your specific situation.

How can I find out if I qualify for specific solar incentives?

Generally, solar incentives apply to:

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

Specific incentives, including those run by the California government or by your county/municipality, might have additional qualifications. Talk to your local Vacaville solar installer to discover what incentives your project may qualify for.

I already have solar panels installed. Are there any incentives that I qualify for?

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

How long until the federal solar tax credit ends?

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