The phrase "solar incentives" generally refers to financial incentives put in place by solar companies and the government to encourage the adoption and use renewable energy by making solar panels more affordable. Incentives might include things like discounts, cash back or monthly utility bill credits. Some incentives are offered federally, while others are offered by the state of California or your specific utility company, county or municipality. Types of solar incentives might include:

  • Tax Exemptions: Your solar panel system may qualify for exemptions on both sales and property tax. Sales tax exemptions are applied at the time of purchase. Property tax exemptions allow you to exclude the value added by your solar panels when calculating property taxes on your house.
  • Solar Renewable Energy Certificate (SREC): SRECs can be sold to your utility company (or other buyers) for cash that typically becomes part of your taxable income. Generally, there is a small threshold of energy production to meet before your solar system can earn SRECs or similar performance-based incentives. Incentives like these are normally handled by your state government.
  • Tax Credits: Tax credits are dollar-for-dollar reductions (not deductions) in how much in taxes you owe the federal government.
  • Net Metering: Don't forget to talk to your Castro Valley utility company about signing a net metering contract. This allows you to receive credit towards your monthly utility bill for the value of excess energy generated by your solar panels. You may receive either a dollar-for-dollar credit or a percentage of the value.
  • Rebates: Some solar companies will help you claim a rebate, or partial refund after purchase, for your solar system. States or counties will also offer limited-time rebates at various times. The value of a rebate will usually be deducted from the total price before any tax credits are calculated.

Federal Solar Incentives

Federal incentives are the type of incentives that you are most likely to have some knowledge of. One of the incentives that most people are likely familiar with is the Federal Solar Investment Tax Credit (ITC). This incentive is a tax credit for a specified percentage of the cost of your solar system.

The ITC applies towards solar systems installed after January 1, 2006, and under this program you can deduct from your taxes a percentage of the total cost of solar panels, accessories, equipment and labor. You can receive this credit for solar panels installed on a primary or secondary residence in the United States that you own. The original claim amount was 30% of the total cost, although the amount you can claim may range between 26-30%. There is no maximum amount you can claim.

Your local Castro Valley solar panel installer can offer more information about the ITC and how it applies to your situation.

The ITC was renewed and increased in scope after the passage of the Inflation Reduction Act in August 2022. It's also 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. The amount will then decrease slightly each year until the current program ends. The expansion to the program also makes claiming credit for energy storage systems easier than ever before, beginning in 2023.

More information about the new Inflation Reduction Act can be found here. The best way to understand how the new Clean Energy Credit will apply to you is to speak with your local Castro Valley solar panel installation expert directly.

State & Local Solar Incentives

There are more than just federal solar incentives; tax credits, rebates and more might also be offered at the state and local level. Incentives may be given by your county or municipality, or by the state of California. Some incentives are available for only a limited time, while others are ongoing.
