Solar incentives are designed to mitigate the cost of installing solar panels on your home. Financial incentives like these are in place to encourage more people to make the switch to renewable energy. The incentives could include upfront discounts, cash back or monthly credits towards your utility bill. Some incentives are offered by the federal government, some by the state of California and some by your specific utility company, county or municipality. Categories of solar incentives include:

  • Rebates: Some solar companies will help you claim a rebate, or partial refund after purchase, for your solar panels. States or counties will also sometimes offer limited-time rebates. Any rebates you receive will usually come off the total price before tax credits are calculated.
  • Tax Credits: Different from tax deductions, tax credits are dollar-for-dollar reductions in the amount of income tax that you owe the government.
  • Tax Exemptions: Sales tax exemptions are applied at the time of purchase for your solar panels. Property tax exemptions allow you to exclude the added value of your solar system when calculating the amount of property tax you need to pay on your house.
  • Net Metering: Net metering becomes relevant once your solar panels are up and running. If you've signed a net metering agreement with your Fullerton utility company, they will subtract the value of the excess energy produced by your solar system from your monthly utility bill. In some places, this is a dollar-for-dollar credit, while in other places you may make back a percentage of the value.
  • Solar Renewable Energy Certificate (SREC): SRECs can be sold to your utility company (or other buyers) for money that is generally considered part of your taxable income. In most cases, a certain (small) threshold of energy production must be met before your solar system is eligible for SRECs or similar performance-based incentives. Incentives like these are typically handled by your state government.

Federal Solar Incentives

Federal incentives are the type of incentives that you are most likely to have heard of. You may have heard of the Federal Solar Investment Tax Credit, or ITC. This incentive is a tax credit that reduces your taxes by a certain percentage of the money you spend on your solar system.

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

Contacting your local Fullerton solar panel installer is the best way to understand how the ITC could apply to you.

In August 2022, the Inflation Reduction Act laid out new provisions for the ITC, now titled the Clean Energy Credit. The Clean Energy Credit re-raises the credit up to 30% for solar systems installed between 2022 and 2032. After 2032, the percentage will decrease slightly each year until the program expires in 2035. Starting in 2023, the expansion to the program will also make claiming credit for energy storage systems easier than ever before.

More information about the new Inflation Reduction Act can be found here. Your local Fullerton solar panel company is the best resource for answering your questions about the new Clean Energy Credit and how it may apply to you.

State & Local Solar Incentives

Not all solar incentives are federal; tax credits, rebates and more might also be offered at the state and local level. Some incentives are ongoing, while others are available for a limited time. They may be offered by the California government, or by your county or municipality.

Next Steps for Installing Solar in Fullerton

The expanding number of solar incentives available has enormously increased the adoption of solar energy nationwide over the last 15 years. You might qualify for solar incentives from your local utility company, the federal government or the California government. If you're ready to make the change to solar energy, talking to your local Fullerton solar panel installation expert is an excellent place to start.

EcoWatch's Fullerton, CA Solar Incentives FAQs

What are some environmental benefits of installing solar panels on my home?

Solar energy is a renewable energy source — by changing where you get your energy, you can help lessen the strain on our planet's resources. Solar panels can also lower your home's CO2 emissions by 250 pounds a year, or around 5,000 pounds in 20 years.

When does the federal solar tax credit end?

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

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

With the passage of the new Inflation Reduction Act, there are a variety of new financial incentives that are available when you make eco-friendly improvements to your home. More details regarding these incentives, including information about incentives for purchasing new appliances, can be found here.

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

Yes, you can receive both rebates and tax credits towards the cost of solar panels. Depending on precisely which incentives you are applying for, they may apply in a different order. Be sure to talk to your solar installer or a local tax professional to confirm that you are claiming the correct incentives and getting the most money you can.

Can I use multiple types of renewable energy to power my home?

Yes, you can employ multiple types of renewable energy to power your home, such as a combination of wind and solar. You can also combine renewable energy generation with a non-renewable backup source of energy. Make sure that you discuss your proposed plan with your local Fullerton solar panel installer, to make sure you know what you'll need and what kinds of incentives you will or won't qualify for.
