Solar incentives are intended to make renewable energy usage more affordable through financial incentives for those who install solar panels on their homes. You may be eligible for several types of incentives, including discounts, cash back or credit towards your monthly utility bill, depending on your situation. Certain 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:

  • Tax Credits: Tax credits reduce, dollar-for-dollar, how much income tax you owe the federal government. Tax credits are different from tax deductions.
  • Rebates: A solar rebate is a partial refund given after you've purchased your solar system. These might be offered by your local utility company, your county or your state. The discount that rebates offer is normally applied to the price of solar panels before calculating tax credits.
  • Net Metering: Net metering factors in once your solar panels are up and running. If you have a net metering agreement in place with your San Diego utility company, the company will subtract the value of the excess energy your solar system produces from your utility bill each month. In some places, this is a dollar-for-dollar credit, while in others you might make back a percentage of the value.
  • Tax Exemptions: Sales tax exemptions are applied at the time of purchase for your solar system. Property tax exemptions let you ignore the value added by your solar system when you calculate how much property tax you need to pay on your home.
  • Solar Renewable Energy Certificate (SREC): SRECs and other performance-based incentives are usually handled by your state government. Once your solar panel system meets a predetermined threshold (generally a small amount of energy production), you are eligible to receive SRECs that can then be sold to your utility company or other buyers. The money you receive from the sale is generally considered part of your taxable income.

Federal Solar Incentives

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

The ITC applies to the value of a solar system installed on your primary or secondary residence in the United States. The solar system has to have been installed on a property you own after January 1, 2006, for you to claim the credit. Initially, the ITC applied to 30% of all system installation costs (panels, accessories, equipment and labor), although the covered amount has fluctuated over time between 26-30%. The amount you qualify for will depend on when your solar system was installed. There is no cap on the amount you can claim.

To understand exactly how much the ITC could save you, talk to your local San Diego solar panel installation expert.

In August 2022, the Inflation Reduction Act expanded and extended the ITC, now called the Clean Energy Credit. The Clean Energy Credit runs until 2035. Any solar installation project that is completed between January 1, 2022, and December 31, 2032, may qualify for a 30% tax credit. This amount will then decrease slightly on a yearly basis until the end of the current program. Starting in 2023, the expansion will also make it easier to get credit for energy storage systems.

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

State & Local Solar Incentives

Some solar incentives are often also provided by state and local governments. Similar to federal incentives, these may include tax credits, rebates and more. These incentives may be given out by your county or municipality, or by the California government. Some incentives may be available for a limited time, while others are ongoing.

Talk with your solar installer or a local tax professional to confirm you are claiming all the incentives you're eligible for and applying them in the correct order.
