Solar incentives are meant to help mitigate the cost of installing a solar panel system on your home. This category of financial incentives is designed to encourage more Americans to switch their home over to renewable energy. Incentives might include things like discounts, cash back or monthly utility bill credits. Some incentives are offered federally, while others are offered by the state of California or by your utility company, county or municipality. Types of solar incentives might include:

  • Tax Exemptions: Sales tax exemptions are effective at the point of sale for your solar panels. Property tax exemptions let you exclude the value that your solar panels add when calculating the amount of property tax you need to pay.
  • Solar Renewable Energy Certificate (SREC): SRECs and similar performance-based incentives are usually handled at the state level. Once your solar panel 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 receive is generally considered part of your taxable income.
  • Tax Credits: Tax credits reduce, dollar-for-dollar, the amount of income tax you owe the federal government. These are different from tax deductions.
  • Net Metering: You can sign a net metering contract with your Castro Valley utility company, that may apply to all or a percentage of the excess electricity that is generated by your solar panels. Your utility company will then subtract this value from your monthly utility bill.
  • Rebates: Solar companies may help you claim a rebate, or partial refund of your purchase, for your solar panels. States or counties will also offer limited-time rebates at various times. Any rebates you receive will usually be deducted from the total price before any tax credits are calculated.

Federal Solar Incentives

Federal incentives are the type of incentives that you are most likely to have some knowledge of. One of the incentives that most people are likely familiar with is the Federal Solar Investment Tax Credit (ITC). This incentive is a tax credit for a specified percentage of the cost of your solar system.

The ITC applies towards solar systems installed after January 1, 2006, and under this program you can deduct from your taxes a percentage of the total cost of solar panels, accessories, equipment and labor. This credit can apply towards 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 claim amount.

Talking to your local Castro Valley solar panel installation expert is the best way to learn more about how the ITC applies to you.

The Inflation Reduction Act, passed in August 2022, made some changes to the ITC (as well as renaming it to the Clean Energy Credit). Now, solar installation projects that are completed between 2022 and 2032, might qualify for a 30% tax credit. This percentage will then decrease slightly each year until the current Clean Energy Credit expires in 2035. The expansion to the program also makes it easier to get credit for energy storage systems, beginning in 2023.

More information about the new Inflation Reduction Act can be found here. Your local Castro Valley solar panel installation expert is the best person to answer your questions regarding the new Clean Energy Credit and how it will apply to you.

State & Local Solar Incentives

Rebates, tax credits and more might be claimed at multiple levels. In addition to federal solar incentives, there are often state and local ones as well. Incentives might be offered by the state of California, or by your county or municipality. Some incentives are available for only a limited time, while others are ongoing.

EcoWatch's Castro Valley, CA Solar Incentives FAQs

How can I learn if I qualify for solar incentives?

It's a good idea to talk to your local Castro Valley solar installer to get an understanding of which incentives your project will qualify for. In most cases, solar incentives apply to new solar panel systems installed on a property you own (in the U.S.) between the dates specified by the incentive. Some incentives, such as those provided by the California government, may have additional requirements.

I already have solar panels installed. Are there any incentives that I qualify for?

If your solar system was installed after January 1, 2022, you may qualify for the recently increased 30% tax credit under the Inflation Reduction Act. If you installed your system between 2006 and 2021, you may qualify for a tax credit between 26% and 30%, depending on the exact installation date. Talking to the company that installed your solar system, or any local Castro Valley solar installer, can help you understand what incentives you qualify for.

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

On average, homeowners in Castro Valley who install solar panels save around $1,749.02 per year, or around $33,231.29 over 20 years after they make the switch.

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

You can reduce your carbon footprint by 250 pounds of CO2 annually when you switch to solar panels. This adds up to approximately 5,000 pounds over 20 years. Solar is also a renewable energy source, meaning that switching your home over lessens the drain on our planet's resources.

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 use both renewable energy sources and a non-renewable backup source of energy. Be sure to discuss your plan with your local Castro Valley solar installation expert, so that you understand what you'll need and what kinds of incentives you might or might not qualify for.
