The phrase "solar incentives" refers broadly to financial incentives that are in place to encourage the adoption and use renewable energy by making solar panels more affordable. Different types of incentives, like discounts, cash back or monthly utility bill credits, might be available to you. Certain incentives may be handled by the California government, by your utility company or by county or municipality, while others are federal. Types of solar incentives might include:

  • Solar Renewable Energy Certificate (SREC): SRECs and similar performance-based incentives are generally handled by your state government. Once your solar panel system meets a predetermined threshold (typically a small amount of energy production), you are eligible to receive SRECs that you can then sell to your utility company or other buyers. The money you receive from the sale is usually considered part of your taxable income.
  • Net Metering: Be sure to speak to your Walnut utility company about signing a net metering contract. This allows you to get a credit towards your monthly utility bill for the value of excess energy your solar panels generate. You could receive either a dollar-for-dollar credit or a percentage of the value.
  • Tax Exemptions: Tax exemptions may come in one of two forms. The first is sales tax exemption, applied when you purchase solar panels. The second is property tax exemption. This allows you to ignore the added value of your solar system when calculating property tax for your house.
  • Tax Credits: Tax credits reduce, dollar-for-dollar, the total amount of tax you owe the federal government. These are different from tax deductions.
  • Rebates: Solar rebates might be offered by your county or state, or by your local utility company. These rebates are essentially cash back that is applied after you purchase solar panels and before tax credits are calculated.

Federal Solar Incentives

When thinking about solar incentives, federal incentives may 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 specific percentage of the cost of your solar system.

The ITC initially applied to 30% of the cost of installing a solar system, although that number has fluctuated slightly over the last few years between 26-30%. The installation date of your solar system will determine what percentage you qualify for. The total installation cost includes the panels themselves as well as the cost of labor, equipment and accessories. There is no maximum claim amount. The ITC applies to solar panels installed after January 1, 2006 on your primary or secondary residence. The residence must be owned by you and in the United States.

To better understand how the ITC may apply to you, call your local Walnut solar panel installer and request more information.

In August 2022, the ITC (now called the Clean Energy Credit) was expanded and extended by the passage of the Inflation Reduction Act. For solar system installations that begin after January 1, 2022 and are completed by the end of 2032, homeowners can receive a credit for 30% of the total cost. After 2033, the percentage will decrease annually until the Clean Energy Credit ends in 2035. Beginning in 2023, it will also be easier to claim credits for energy storage systems under the new laws.

State & Local Solar Incentives

Some solar incentives may be offered at the local or state level. Like with federal incentives, these may include tax credits, rebates and more. The incentives — which might be handled by your county or municipality, or by the state of California — could be offered on an ongoing basis, or for only a limited time.

Next Steps for Installing Solar in Walnut
