Solar incentives are designed to make renewable energy usage more affordable through financial incentives for those who install solar panels on their homes. Incentives might include things like discounts, cash back or credit towards your monthly utility bill. Some incentives are handled federally, while others are offered by the state of California or your specific utility company, county or municipality. Some broad categories of solar incentives include:

  • Tax Credits: Unlike tax deductions, tax credits are dollar-for-dollar reductions in the amount of income tax that you owe the federal government.
  • Tax Exemptions: Sales tax exemptions are applied at the time of purchase for your solar panels. Property tax exemptions allow you to ignore the value that your solar panels add when you're calculating how much property tax you need to pay on your home.
  • Rebates: Rebates, or cash back after a purchase, are usually given prior to any solar tax credits being calculated. Solar rebates may be provided by your local utility company, by your state or by your county.
  • Solar Renewable Energy Certificate (SREC): SRECs are credits that can be sold to your utility company (or other buyers) for cash that normally counts as part of your taxable income. Typically, a certain (small) threshold of energy production must be met before your solar system is eligible for SRECs or similar performance-based incentives. These kinds of incentives are typically handled at the state level.
  • Net Metering: Net metering factors in after your solar system is up and running. If you have a net metering agreement in place with your Portola Valley utility company, they will subtract the value of the excess energy your solar system produces from your monthly utility bill. In some areas, this is a dollar-for-dollar credit, while in others you might be refunded a percentage of the value.

Federal Solar Incentives

Federal solar incentives are likely to be the first thing that you think of when thinking about solar incentives. The solar incentive that you're most familiar with is probably the Federal Solar Investment Tax Credit (ITC), which provides a credit on your taxes equal to a predetermined percentage of your solar system's cost.

The ITC can be applied to the total cost of installing a solar system, including the panels themselves as well as equipment, labor and accessories. This credit can be claimed for panels installed after January 1, 2006 on a primary or secondary residence that you own and that is located in the United States. Originally set at 30% of total costs, the credit has fluctuated over time, and you may qualify for different amounts depending on when your project was completed. There is no maximum claim amount.

Have questions about how the ITC applies to your specific situation? Contact your local Portola Valley solar panel installation expert to get 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. With the new provisions, solar installation projects begun after January 1, 2022 and finished by December 31, 2032 might qualify for a 30% tax credit. This credit amount 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.

State & Local Solar Incentives

Some solar incentives may be offered at the local or state level. Like with federal incentives, these can include tax credits, rebates and more. These incentives might be offered by the California government, or by your county or municipality. Some are available for a limited time, while others are ongoing.

Next Steps for Installing Solar in Portola Valley
