Solar incentives are designed to mitigate the cost of installing solar panels on your home. These financial incentives are designed to encourage more people to switch to renewable energy. Different kinds of incentives, like cash back, discounts or credit towards your monthly utility bill, may be available to you. Some incentives may be handled by the California government, by your utility company or by county or municipality, while others are federal. You might qualify for any of the following types of solar incentives:

  • Net Metering: Net metering is an incentive you can get after your solar panels are up and running. If you've signed a net metering agreement with your Vacaville utility company, the company will subtract the value of the excess energy produced by your solar system from your monthly utility bill. In some areas, this credit is dollar-for-dollar, while in other areas you might receive a refund equivalent to a percentage of the value.
  • Tax Credits: Unlike tax deductions, tax credits reduce, dollar-for-dollar, the amount of income tax that you owe the government.
  • Rebates: A solar rebate is a partial refund credited to your account after you've paid for your solar system. These may be offered by your local utility company, your state or your county. The rebates are usually applied before tax credits are calculated.
  • Tax Exemptions: These could come in the form of property tax exemptions, which can let you exclude the value of your solar system when calculating the taxes you pay on your home. You could also look for exemptions on sales tax at the time of purchase.
  • Solar Renewable Energy Certificate (SREC): SRECs are credits that can be sold to your utility company (or other buyers) for cash that is generally considered part of your taxable income. In most cases, there is a small threshold of energy production to meet before your solar system qualifies for SRECs or other performance-based incentives. These kinds of incentives are generally handled by your state government.

Federal Solar Incentives

Federal incentives are the type of incentives that you are most likely to have some knowledge of. You've likely heard of the Federal Solar Investment Tax Credit, or ITC. This is a tax credit that reduces your taxes by a specified percentage of the money you spend on solar panels for your home.

The ITC applies towards solar systems installed after January 1, 2006, and allows you to deduct from your taxes a percentage of the total cost of solar panels, accessories, labor and equipment. This credit can be claimed on solar panels installed on a primary or secondary residence that you own in the United States. Originally, you could claim 30% of the total cost, although depending on when the project was completed, your credit may range from 26-30%. There is no maximum amount you can claim.

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

The Inflation Reduction Act, passed in August 2022, made some changes to the ITC (as well as retitling it the Clean Energy Credit). Homeowners are now eligible for a credit equal to 30% of the total costs of solar system installation for projects that began after January 1, 2022, and will be finished by the end of 2032. The percentage will then begin to decrease on a yearly basis until the Clean Energy Credit expires in 2035. 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. Your local Vacaville solar panel company can answer your questions and explain how the new Clean Energy Credit may apply to you.

State & Local Solar Incentives

There are more than just federal solar incentives; rebates, tax credits and more are often offered at the state and local level. Certain incentives are ongoing, while others are available for a limited time. Solar incentives might be offered by the California government, or by your county or municipality.

Next Steps for Installing Solar in Vacaville

EcoWatch's Vacaville, CA Solar Incentives FAQs

How do I learn if I qualify for certain solar incentives?

It's best to speak with your local Vacaville solar installer to get an understanding of which incentives your project will qualify for. In most cases, solar incentives apply to new solar systems installed on property you own (in the U.S.) within a specified date range. Some incentives, such as those provided by the California government, may have additional requirements.

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

Solar energy is a renewable energy source — by changing where you get your energy, you help reduce the strain on our planet's resources. You can also lower the CO2 emissions from your home by 250 pounds annually, 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 benefits I can claim?

The recently passed Inflation Reduction Act introduces a number of incentives that reward homeowners who make eco-friendly upgrades. Some of these 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 that incentives will be applied in may vary depending on which incentives you are eligible for but in most cases yes, you can claim multiple types of incentives for your solar project. Talk with your solar installer or a local tax professional to confirm you are claiming all the incentives you qualify for and applying them in the correct order.
