Solar incentives are designed to make renewable energy usage more affordable via financial incentives to help people install solar panels on their homes. The incentives might include upfront discounts, cash back or monthly credits towards your utility bill. Some incentives are handled by the federal government, some by the California government and some by your specific utility company, county or municipality. Some solar incentives you might qualify for are:

  • Solar Renewable Energy Certificate (SREC): Generally, solar systems that produce over a threshold (generally small) amount of electricity can qualify for SRECs or other similar performance-based incentives. SRECs and the like are typically offered at the state level. SRECs can be sold to your utility company or another buyer, and generally the money you make is normally considered part of your taxable income.
  • Rebates: A solar rebate is a partial refund credited to your account after you've paid for your solar panels. These could be offered by your local utility company, your county or your state. The rebates are usually applied before calculating tax credits.
  • Tax Exemptions: These may come in the form of property tax exemptions, which would allow you to ignore the value added by your solar panels when paying property tax on your home. You could also look for exemptions on sales tax at the time of purchase.
  • Net Metering: Net metering factors in once your solar system is up and running. If you've signed a net metering agreement with your San Mateo utility company, they will subtract the value of the excess energy your solar system produces from your monthly utility bill. In some places, this is a dollar-for-dollar credit, while in other places you may be refunded a percentage of the value.
  • Tax Credits: Tax credits are dollar-for-dollar reductions that lower the amount of income tax you owe the government. (A tax credit is different from a tax deduction.)

Federal Solar Incentives

Federal incentives are the type 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. This is a tax credit equal to a specified percentage of the money you spend installing solar panels.

The ITC can be applied to the total cost of installing solar panels, including the panels themselves as well as equipment, labor and accessories. You can claim this credit for panels installed after January 1, 2006 on a primary or secondary residence that you own and that is located in the United States. The tax credit ranges from 26-30% of total costs depending on when your project was completed. There is no maximum amount you can claim.

Your local San Mateo solar panel installer can give you more information about the ITC and how it might 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. For solar systems installed between January 1, 2022 and December 31, 2032, homeowners may be eligible for a credit for 30% of the total cost. This percentage will decrease annually after 2032 until the Clean Energy Credit ends in 2035. Starting in 2023, it will also be easier to obtain credits for energy storage systems under the new laws.

State & Local Solar Incentives

Federal solar incentives are not your only option; tax credits, rebates and more are often offered at the state and local level. Some incentives are ongoing, while others are offered for only a limited time. These local incentives could come from your county or municipality, or from the California government.

EcoWatch's San Mateo, CA Solar Incentives FAQs

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

While we recommend getting in touch with your local solar installer and/or tax professional to best understand what solar incentives apply to you, many incentives can be claimed on a second home, so long as that home is in the United States and owned by you. There may be additional incentives available for commercial properties specifically, depending on the details.

How much can I save annually on my electric bill if I add solar panels to my San Mateo home?

On average, homeowners in San Mateo who install solar panels save about $1,716.16 per year, or about $32,606.96 over 20 years after making the switch.

How long until the federal solar tax credit ends?

The Clean Energy Credit (formerly named the federal solar tax credit, or the ITC), is slated to end on January 1, 2035. Currently set at 30%, the credit will drop to 26% in 2033 and to 22% in 2034.

I want to switch my appliances out for ones that are more energy-efficient. Are there any incentives I can claim?

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

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 discuss your plan with your local San Mateo solar installer. They can help you plan your project and also help you understand the various incentives that you might or might not qualify for.
