Solar incentives are designed to make renewable energy usage more affordable via financial incentives for those who install solar panels on their homes. Incentives may include things like discounts, cash back or credit towards your monthly utility bill. Some incentives are offered by the federal government, while others are handled by the state of Colorado or your utility company, county or municipality. You might qualify for any of the following types of solar incentives:

  • Net Metering: Net metering factors in after your solar panels are up and running. If you've signed a net metering agreement with your Centennial utility company, the company will subtract the value of the excess energy produced by your solar system from your utility bill each month. In some locations, this credit is dollar-for-dollar, while in other places you may make back a percentage of the value.
  • Tax Credits: Tax credits decrease, dollar-for-dollar, the total amount of tax you owe the federal government. These differ from tax deductions.
  • Tax Exemptions: Tax exemptions may come in one of two forms. The first is sales tax exemption, which is applied when you purchase 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 home.
  • Rebates: Rebates, or cash back after a purchase, are typically given prior to any solar tax credits being calculated. Rebates might be offered by your local utility company, by your state or by your county.

Federal Solar Incentives

Federal solar incentives are likely the first thing that you think of when thinking about solar incentives. One of the incentives that most people are likely familiar with is the Federal Solar Investment Tax Credit (ITC). The ITC is a tax credit for a predetermined percentage of the cost of your solar system.

The ITC applies to the total cost of installing solar panels, including the panels themselves as well as labor, equipment and accessories. This credit can be claimed for panels installed after January 1, 2006, on a primary or secondary residence located in the United States that you own. From its original value of 30% of the total cost, the credit has fluctuated slightly between 26-30%, and you may qualify for varying percentages depending on when your project was completed. There is no maximum claim amount.

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

In August 2022, the ITC (now referred to as the Clean Energy Credit) was expanded and extended by the passage of the Inflation Reduction Act. The Clean Energy Credit is valid until 2035. Solar installation projects started after January 1, 2022, and completed by the end of 2032 may qualify for a 30% tax credit. The amount will then decrease slightly on a yearly basis until the current program ends. Starting in 2023, the expansion to the program will also make it easier to get credit for energy storage systems.

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 applies to you is to reach out to your local Centennial solar panel installers with your questions.

State & Local Solar Incentives

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

Next Steps for Installing Solar in Centennial

You can apply for and receive solar incentives from the Colorado government and the federal government, as well as from your local utility company. Growing availability of solar initiatives in the past 15 years has helped increase nationwide solar energy use enormously. It is a good idea to talk to your local Centennial solar installation expert to learn more about these incentives and to make sure that you're getting all the money you can for your solar panels.

EcoWatch's Centennial, CO Solar Incentives FAQs

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

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

How much will solar panels save me on my electric bill in Centennial annually?

On average, Centennial homeowners who install solar panels save around $1,057.22 per year, or about $20,087.17 over 20 years after they make the switch.

When does the federal solar tax credit end?

The federal solar tax credit, formerly called the ITC and now named the Clean Energy Credit, is set to end 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 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 generally yes, you can claim multiple types of incentives for your solar project. Get in touch with your solar installer or a local tax professional to verify you are claiming all the incentives you qualify for and applying them in the correct order.

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

Many solar incentives apply to a property you own that is located within the United States; most secondary residences fall into this category. Other solar incentives may be available for commercial properties, depending on the details. We recommend speaking with your local solar installer and/or tax professional to better understand what incentives may apply to your specific situation.
