The phrase "solar incentives" refers to a range of financial incentives implemented to make installing and using solar panels more affordable. This is done to encourage people to switch to renewable energy. Solar incentives can include cash back, upfront discounts or monthly credits towards your utility bill. Some incentives are handled by the federal government, some by the state of California and some by your specific utility company, county or municipality. You might qualify for any of the following types of solar incentives:

  • Tax Credits: Tax credits decrease, dollar-for-dollar, the amount of income tax you owe the government. These differ from tax deductions.
  • Rebates: Solar rebates may be provided by your state or county, or by your local utility company. These rebates work as partial refunds that are applied after your purchase of a solar system and before tax credits are calculated.
  • Tax Exemptions: These can come in the form of property tax exemptions, which would allow you to exclude the value added by your solar panels when paying property tax on your home. You could also look for exemptions on sales tax at the time of purchase.
  • Net Metering: Make sure you speak to your Mill Valley utility company about signing a net metering contract. This will allow you to get a credit towards your monthly utility bill 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.
  • Solar Renewable Energy Certificate (SREC): In most cases, solar systems that produce over a threshold (generally small) amount of electricity qualify for SRECs or other performance-based incentives. SRECs and the like are typically provided by your state government. When you receive an SREC, you can sell it to your utility company or another buyer, and generally the money you make is normally considered part of your taxable income.

Federal Solar Incentives

When people think of solar incentives, federal incentives are likely the first thing that comes to mind. You've likely heard of the Federal Solar Investment Tax Credit, or ITC. This incentive is a tax credit that reduces your taxes by a predetermined percentage of the money you spend installing solar panels.

The ITC covers 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. You can claim this credit for a solar panel system installed on a primary or secondary residence that you own in the United States. The original claim amount was 30% of the total cost, although the amount you can claim may range between 26-30%. There is no maximum amount you can claim.

Curious how the ITC might apply to your specific situation? Reach out to your local Mill Valley solar panel installer to get 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. The Clean Energy Credit lasts until 2035. Your solar installation project undertaken between 2022 and 2032 may qualify for a 30% tax credit; this amount will decrease slightly on a yearly basis until the end of the current program. Beginning in 2023, it will also be easier to qualify for credits for energy storage systems under the new laws.

State & Local Solar Incentives

Some solar incentives are often also provided at the state and local level. Similar to federal incentives, these might include rebates, tax credits and more. Some incentives are offered for only a limited time, while others are ongoing. These local incentives may come from the California government, or from your specific county or municipality.

EcoWatch's Mill Valley, CA Solar Incentives FAQs

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

It's a good idea to talk to your local Mill Valley solar installer for a better understanding of which incentives your project may qualify for. In most cases, solar incentives apply to new solar panel systems installed on a property you own (in the U.S.) within a specified date range. Some incentives, such as those provided at the level of the California government, might have other requirements.

If I already have a solar system installed on my house, can I still claim incentives?

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

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

You can reduce your carbon footprint by 250 pounds of CO2 annually by switching to solar panels. This adds up to roughly 5,000 pounds in 20 years. In addition, solar power is a renewable energy source, meaning that switching your home over reduces the drain on our planet's resources.

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

The new Inflation Reduction Act creates a number 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.

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

Yes, you can claim both tax credits and rebates towards the cost of solar panels. Depending on precisely which incentives you are receiving, they may apply in a different order. Be sure to speak with your solar installer or a local tax professional to verify that you are claiming the correct incentives and getting the most money possible.
