The term "solar incentives" includes a wide range of financial incentives designed to make installing and using solar panels more affordable. This is done to encourage people to switch to renewable energy. Different kinds of incentives, like discounts, cash back or credit towards your monthly utility bill, may be available to you. Some incentives may be provided via the California government, by your utility company or by county or municipality, while others are federal. Categories of solar incentives include:

  • Tax Exemptions: Your solar panels could qualify for both sales tax and property tax exemptions. Sales tax exemptions are applied at the time of purchase. Property tax exemptions let you exclude the value added by your solar panels when calculating property taxes on your home.
  • Solar Renewable Energy Certificate (SREC): SRECs and similar performance-based incentives are usually handled at the state level. Once your solar panel system meets the threshold (typically a small amount of energy production), you are eligible to receive SRECs that can be sold to your utility company or other buyers. The money you receive from the sale is usually considered part of your taxable income.
  • Rebates: Some solar companies will help you claim a rebate, or partial refund after purchase, for your solar panels. Counties or states will also offer limited-time rebates at various times. If you receive a rebate, that amount will usually come off the total price before tax credits are calculated.
  • Tax Credits: Unlike tax deductions, tax credits are dollar-for-dollar reductions in the amount of income tax that you owe the federal government.
  • Net Metering: Make sure you talk with your Tustin utility company about signing a net metering agreement. This will allow you to receive credit towards your utility bill every month 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.

Federal Solar Incentives

When someone says "solar incentives," you likely think of federal incentives first. You may have 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 on your solar system.

The ITC applies to solar panels installed after January 1, 2006, on a primary or secondary residence that you own in the United States. Originally, the tax credit was for 30% of the total cost – for panels, equipment, accessories and labor – although the percentage may range from 26-30%, depending on the installation date of your solar system. There is no cap on the claim amount.

Have questions about how the ITC applies to your specific situation? Contact your local Tustin solar panel installation expert to get more information.

In August 2022, the ITC (now referred to as the Clean Energy Credit) was bolstered by the passing of the Inflation Reduction Act. The new Clean Energy Credit now runs until 2035. American homeowners can now receive a 30% credit for solar systems that began installation after January 1, 2022, and are completed by the end of 2032. The total credit will then decrease annually until the date of expiration. The program expansion also makes claiming credit for energy storage systems easier than ever before, starting in 2023.

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

EcoWatch's Tustin, CA Solar Incentives FAQs

How do I know if I qualify for solar incentives?

It's a good idea to talk to your local Tustin solar installer to get an understanding of which incentives your project may qualify for. Usually, solar incentives apply to new solar systems installed on a property you own (in the U.S.) within a specified date range. Some incentives, such as those given by the state of California, may have other requirements.

What are some environmental benefits of adding solar panels to my house?

Solar energy is a renewable energy source — by switching where you get your energy, you can help reduce the strain on our planet's resources. You can also lower the CO2 emissions from your home by 250 pounds yearly, or around 5,000 pounds over 20 years.

I want to change out my appliances for ones that are more energy-efficient. Are there any credits I can apply for?

The new Inflation Reduction Act introduces a number of incentives designed to reward homeowners for making eco-friendly upgrades. Some incentives include rebates and tax credits for installing new electric appliances. You can find more details about these incentives here.

Can I apply for incentives both towards the up-front cost of solar panels, and later as reimbursement?

The order your incentives will be applied in could vary depending on which incentives you receive but in most cases yes, you can receive multiple types of incentives for your solar project. Talk with your solar installer or a local tax professional to make sure you are claiming all possible incentives and applying them in the correct order.
