The phrase "solar incentives" covers a range of financial incentives designed to make installing and using solar panels more affordable. This is done to encourage people to switch to renewable energy. Incentives can include things like discounts, cash back or credit towards your monthly utility bill. Some incentives are provided by the federal government, while others are handled by the California government or by your utility company, county or municipality. Categories of solar incentives include:

  • Solar Renewable Energy Certificate (SREC): SRECs can be sold to your utility company (or other buyers) for cash that typically becomes part of your taxable income. In most cases, there is a small threshold of energy production to meet before your solar system qualifies for SRECs or other performance-based incentives. SRECs and similar incentives are typically handled by your state government.
  • Net Metering: Net metering becomes relevant after your solar panels are up and running. If you have in place a net metering agreement with your Costa Mesa utility company, it will subtract the value of the excess energy produced by your solar system from your monthly utility bill. In some areas, this is a dollar-for-dollar credit, while in other areas you might get refunded a percentage of the value.
  • Tax Exemptions: Sales tax exemptions are applied at the time of purchase for your solar system. Property tax exemptions allow you to ignore the added value of your solar system when you're calculating the amount of property tax you need to pay.
  • Tax Credits: Tax credits are dollar-for-dollar reductions in the amount of income tax that you owe the federal government. (This is different from a tax deduction.)
  • 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. If you receive a rebate, that amount will usually be deducted from the total price before any tax credits are calculated.

Federal Solar Incentives

Federal incentives are the kind of incentives that you are most likely to have some familiarity with. You've likely heard of the Federal Solar Investment Tax Credit, or ITC. The ITC is a tax credit equal to a specified percentage of the money you spend on your solar system.

The ITC applies to solar panels installed after January 1, 2006, on a primary or secondary residence that you own in the United States. Initially, the credit applied to 30% of the total cost – for panels, equipment, accessories and labor – although the percentage may range from 26-30%, depending on when your solar project was undertaken. There is no cap on the claim amount.

To best understand how the ITC will apply to you, call your local Costa Mesa solar panel installation expert and ask for more information.

The ITC has been renewed and expanded following the passage of the Inflation Reduction Act in August 2022. It's also now called the Clean Energy Credit. Now, 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 end of the current Clean Energy Credit in 2035. Beginning in 2023, it will also be easier to obtain credits for energy storage systems under this new program.

State & Local Solar Incentives

Federal solar incentives are not your only option; rebates, tax credits and more are often offered at the local or state level. These incentives — which might be handled by the state of California, or by your county or municipality — could be offered for only a limited time, or on an ongoing basis.

Next Steps for Installing Solar in Costa Mesa

You can qualify for solar incentives from the California government and the federal government, as well as from your local utility company. The increased availability of solar initiatives over the last 15 years has helped greatly increase nationwide adoption of solar energy. We recommend talking to your local Costa Mesa solar installation company for more information about these incentives and to ensure that you're getting all the money you can for your solar system.

EcoWatch's Costa Mesa, CA Solar Incentives FAQs

How can I learn if I qualify for solar incentives?

In most cases, solar incentives apply to:

  1. a new solar panel 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 ones handled by the California government or by your county/municipality, might have additional qualifications. Get in touch with your local Costa Mesa solar installer to learn more about what incentives your project may qualify for.

How long until the federal solar tax credit ends?

The federal solar tax credit, previously called the ITC and now named 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.

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

The recently passed Inflation Reduction Act introduces multiple incentives that reward homeowners who make eco-friendly upgrades. Some of these incentives include tax credits and rebates for installing new electric appliances. You can find more details about these incentives here.

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

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