Solar incentives are designed to encourage people to switch their home over to renewable energy by offering financial incentives that lower the burden of solar panel installation and use. You might qualify for several types of incentives, including cash back, discounts or credit towards your monthly utility bill, depending on your situation. Some incentives come from your specific utility company, county or municipality, some from the state of California and others from the federal government. Types of solar incentives might include:

  • Net Metering: Net metering is an incentive you can get once your solar panels are up and running. If you have a net metering agreement with your Napa utility company, the company will subtract the value of the excess energy your solar system produces from your monthly utility bill. In some places, this credit is dollar-for-dollar, while in other areas you might receive a refund equivalent to a percentage of the value.
  • Tax Credits: Tax credits are dollar-for-dollar reductions (not deductions) in how much income tax you owe the government.
  • Solar Renewable Energy Certificate (SREC): SRECs and other performance-based incentives are usually handled by your state government. Once your solar system meets a predetermined threshold (usually 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 make is generally considered part of your taxable income.
  • Rebates: Rebates, or partial refunds after a purchase, are usually applied prior to any solar tax credits being calculated. Rebates might be provided by your local utility company, by your state or by your county.
  • Tax Exemptions: Tax exemptions may come in two forms. First, there is sales tax exemption, applied at the time you purchase your solar panels. The second is property tax exemption. This allows you to ignore the value added by your solar system when paying property tax on your house.

Federal Solar Incentives

When you think about solar incentives, you likely think of federal incentives first. The Federal Solar Investment Tax Credit, or ITC, is probably the most commonly known federal solar incentive. The ITC offers a tax credit for a predetermined percentage of the cost of your solar system.

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

To more fully understand how the ITC will apply to you, call your local Napa solar panel installer and ask for more information.

The ITC was both renewed and expanded by the passage of the Inflation Reduction Act in August 2022. It's also now called the Clean Energy Credit. Under the new program, solar installation projects that are completed between 2022 and 2032, can qualify for a 30% tax credit. This credit amount will then see a slight annual decrease until the current Clean Energy Credit expires in 2035. Beginning in 2023, it will also be easier to qualify for credits for energy storage systems under the new laws.

More information about the new Inflation Reduction Act can be found here. To understand how the new Clean Energy Credit will apply to you, talk to your local Napa solar installers.

State & Local Solar Incentives

There are often state solar incentives available in addition to federal ones. Rebates, tax credits and more might be available at a more local level. Certain incentives are ongoing, while others are offered for only a limited time. Local solar incentives might come from your county or municipality, or from the California government.

Next Steps for Installing Solar in Napa

There are many kinds of solar incentives: those offered by the federal government, those given by the California government and those given by local utility companies, to name a few. The use of solar energy has increased enormously in the last 15 years, partially due to these incentives. Getting in touch with your local Napa solar panel installation expert is a great first step towards making sure you get all the incentives you qualify for when you switch to solar energy.

EcoWatch's Napa, CA Solar Incentives FAQs

If my house already has solar panels, can I still claim incentives?

An excellent idea would be to talk to someone from the company that installed your solar system – or get in touch with a local Napa solar installer — to better understand which incentives you might qualify for. If your system was installed after January 1, 2022, you likely qualify for the newly increased 30% tax credit under the Inflation Reduction Act. Systems installed between 2006 and 2021 may qualify for a tax credit of 26-30%.

How much can I save annually on my electric bill if I install solar panels on my Napa home?

Once you add solar panels to your house in Napa, you can anticipate savings of approximately $1,723.39 per year, or approximately $32,744.48 over the next 20 years.

What are some of the environmental benefits of switching to solar energy?

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

How long until the federal solar tax credit ends?

The Clean Energy Credit (previously referred to as the federal solar tax credit, or ITC), is scheduled to end on January 1, 2035. Currently set at 30%, the credit will drop to 26% in 2033 and to 22% in 2034.

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

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