Solar incentives are intended to make renewable energy usage more affordable via financial incentives for individuals who install solar panels on their homes. These incentives can include upfront discounts, cash back or monthly credits towards your utility bill. Some incentives are given by the federal government, some by the state of California and some by your specific utility company, county or municipality. Categories of solar incentives include:

  • Rebates: Rebates, or partial refunds after a purchase, are typically applied before any solar tax credits are calculated. Solar rebates may be provided by your local utility company, by your county or by your state.
  • Solar Renewable Energy Certificate (SREC): SRECs and similar other performance-based incentives may be available to you if you have a solar system that produces over a specified (generally small) amount of electricity. Performance-based incentives are normally handled by the state government. You can sell the SRECs you receive to your utility company or other buyers, and the money you make is generally considered part of your taxable income.
  • Tax Credits: Tax credits are dollar-for-dollar reductions in the amount of income tax that you owe the federal government. (A tax credit is different from a tax deduction.)
  • Net Metering: Net metering is an incentive you can get after your solar system is up and running. If you have a net metering agreement in place with your Walnut utility company, they will subtract the value of the excess energy produced by your solar system from your utility bill each month. In some areas, this credit is dollar-for-dollar, while in other areas you may receive a refund equivalent to a percentage of the value.
  • Tax Exemptions: These may come in the form of property tax exemptions, which can let you exclude the value of your solar system when calculating the taxes you pay on your home. They may also include exemptions on sales tax at the time of purchase.

Federal Solar Incentives

When you hear the term "solar incentives," federal incentives are likely the first thing that comes to mind. A federal incentive many people are likely to be familiar with is the Federal Solar Investment Tax Credit (ITC). The ITC is a tax credit for a given percentage of your solar system's cost.

The ITC originally covered 30% of the total cost of installing a solar system, although it has fluctuated slightly over time between 26-30%. The percentage you qualify for will depend on when your solar system was installed. The total cost of installation includes the panels themselves as well as the cost of accessories, equipment and labor. There is no maximum amount you can claim. The ITC can be applied to solar systems installed after January 1, 2006, on your primary or secondary residence. The residence must be owned by you and in the United States.

Your local Walnut solar panel installation expert can give you more information about the ITC and how it might apply to your situation.

In August 2022, the ITC (now titled the Clean Energy Credit) was expanded and extended by the passing of the Inflation Reduction Act. The new Clean Energy Credit extends until 2035. You can now receive a 30% credit for solar systems installed between January 1, 2022, and December 31, 2032. The total credit will then see a slight annual decrease until the date of expiration. The expansion to the program also makes credits for energy storage systems even easier to claim, beginning in 2023.

More information about the new Inflation Reduction Act can be found here. To best understand how the new Clean Energy Credit will apply to you, reach out to your local Walnut solar installation expert.

State & Local Solar Incentives

In addition to federal solar incentives, there are often also state ones. Rebates, tax credits and more might be available at a more local level. Some incentives are ongoing, while others may only be available for a limited time. These incentives may be provided by your county or municipality, or by the California government.

Next Steps for Installing Solar in Walnut

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

You can use multiple types of renewable energy, or a combination of renewable and non-renewable energy, to power your home. Be sure to talk through your plan with your local Walnut solar installer. They can help you plan your project and educate you on the various incentives that you may or may not qualify for.

Can I claim incentives for adding solar panels to a rental property, vacation home or commercial property?

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