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. These incentives may include upfront discounts, cash back or credit towards your monthly utility bill. Some incentives are handled by the federal government, some by the state of California and some by your specific utility company, county or municipality. Some solar incentives you might qualify for are:

  • Rebates: Solar companies may help you claim a rebate, or partial refund of your purchase, for your solar system. States or counties will also sometimes offer limited-time rebates. If you receive a rebate, that amount will usually be deducted from the total price before tax credits are calculated.
  • Solar Renewable Energy Certificate (SREC): SRECs and similar performance-based incentives might be available to you if the solar system on your home produces over a specified (usually small) amount of electricity. These types of incentives are usually handled at the state level. You can sell SRECs to your utility company or other buyers, and the money you make is typically considered part of your taxable income.
  • Net Metering: You can sign a net metering agreement with your Altadena utility company that will apply to all or a percentage of the excess electricity your solar panels generate. Your utility company will then deduct this value from your utility bill each month.
  • Tax Exemptions: Sales tax exemptions are effective at the time of purchase for your solar system. Property tax exemptions allow you to exclude the value added by your solar system when you calculate how much property tax you need to pay on your house.
  • Tax Credits: These credits are dollar-for-dollar reductions (not deductions) in how much in taxes you owe the federal government.

Federal Solar Incentives

When people think of solar incentives, federal incentives are likely the first thing that comes to mind. The Federal Solar Investment Tax Credit, or ITC, is the most well-known federal solar incentive. The ITC allows you to claim a tax credit for a predetermined percentage of your solar system's cost.

The ITC can be applied to solar systems 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 it may range from 26-30%, depending on when your solar project was undertaken. There is no cap on the amount you can claim.

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

The ITC was both renewed and expanded by the passage of the Inflation Reduction Act in August 2022. It's also now called the Clean Energy Credit. Now, solar installation projects that are completed between 2022 and 2032, can qualify for a 30% tax credit. The amount of the credit will then see a slight annual decrease until the current Clean Energy Credit expires in 2035. Starting in 2023, it will also be easier to obtain credits for energy storage systems under this new program.

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