The term "solar incentives" generally refers to financial incentives that are in place to encourage people to use renewable energy by making solar panels more affordable. Different kinds of incentives, such as cash back, discounts or monthly utility bill credits, may be available to you. Certain incentives may be offered by the state of Colorado, by your utility company or by county or municipality, while others are federal. Types of solar incentives might include:

  • Net Metering: Don't forget to speak with your Boulder utility company about signing a net metering agreement. This allows you to get a credit towards your monthly utility bill for the value of excess energy generated by your solar panels. You might receive either a dollar-for-dollar credit or a percentage of the value.
  • Tax Credits: Tax credits reduce, dollar-for-dollar, the amount of income tax you owe the federal government. Tax credits are different from tax deductions.
  • Tax Exemptions: These might come in the form of property tax exemptions, which can let you ignore the value of your solar system when paying taxes on your house. You could also look for exemptions on sales tax at the time of purchase.
  • Rebates: Your solar installer might help you claim a rebate, or partial refund after purchase, for your solar panels. States or counties will also sometimes offer limited-time rebates. The value of a rebate will usually come off your total price before tax credits are calculated.

Federal Solar Incentives

Federal incentives are the type of incentives that you are most likely to have some knowledge of. It's likely that you've heard of the Federal Solar Investment Tax Credit, or ITC. This incentive is a tax credit equal to a predetermined percentage of the money you spend on solar panels for your home.

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, labor, equipment and accessories. You can receive this credit for a solar panel system installed on a primary or secondary residence that you own in the United States. The original amount you could claim was 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.

Reaching out to your local Boulder solar panel installer is the best way to understand how the ITC could apply to you.

The ITC was renewed and increased in scope after the passage of the Inflation Reduction Act in August 2022. It's also now called the Clean Energy Credit. The new Clean Energy Credit is valid until 2035. American homeowners can now receive a 30% credit for solar systems installed between January 1, 2022, and December 31, 2032. The total credit will then see a slight annual decrease until the date of expiration. Starting in 2023, the expansion 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. The best way to learn more about how the new Clean Energy Credit might apply to you is to reach out to your local Boulder solar panel company with your questions.

State & Local Solar Incentives

Tax credits, rebates and more can be provided at multiple levels. On top of federal solar incentives, there are often state and local ones as well. Some incentives are ongoing, while others are only available for a limited time. They might be given by the Colorado government, or by your county or municipality.

Next Steps for Installing Solar in Boulder

The variety of solar incentives available has contributed greatly to the increase in the use of solar power nationwide over the past 15 years. You may receive solar incentives from your local utility company, the Colorado government or the federal government. It is a good idea to talk to your local Boulder solar installation company for more information about these incentives and to make sure that you're getting the most money possible for your solar panels.

EcoWatch's Boulder, CO Solar Incentives FAQs

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

Generally, solar incentives apply to:

  1. a new solar panel system
  2. installed on property that you own
  3. within the U.S.
  4. between the dates specified by a particular incentive.

Specific incentives, including those given out by the Colorado government or by your county/municipality, could have additional qualifications. Talk to your local Boulder solar installer to find out what incentives your project may qualify for.

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

You can decrease your carbon footprint by 500 pounds of CO2 annually when you install solar panels. This adds up to approximately 11,000 pounds over 20 years. Solar is also a renewable energy source, which means that switching your home over reduces the drain on our planet's resources.

When does the federal solar tax credit end?

The federal solar tax credit, previously called the ITC and now titled the Clean Energy Credit, is set to end on January 1, 2035. The current 30% credit will end in 2032, replaced by a 26% credit in 2033 and a 22% credit in 2034.

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

You can power your home with multiple types of renewable energy, or a combination of renewable and non-renewable energy. Be sure to discuss your plan with your local Boulder solar installation expert. They can help you as you plan for your project and educate you on the various incentives that you may or may not qualify for.

What if I want to add solar panels to a vacation home, rental property or commercial property? Will I still qualify for incentives?

Many solar incentives are intended to apply to a property located within the United States that you own; most secondary residences will fall under this distinction. There may be other solar incentives available for commercial properties, depending on the specifics. We recommend getting in touch with your local solar installer and/or tax professional to best understand what incentives may apply to your specific situation.
