Federal Residential Renewable Energy Tax Credit

The phrase "solar incentives" broadly refers to financial incentives implemented by the government and by solar companies to encourage the use of renewable energy by making installing and using solar panels more affordable. These incentives can include cash back, upfront discounts or credit towards your monthly utility bill. Some incentives are provided by the federal government, some by the Colorado government and some by your utility company, county or municipality. Some solar incentives you might qualify for are:
- Net Metering: You can sign a net metering contract with your Centennial utility company, that may apply to all or a percentage of the excess electricity your solar panels generate. Your utility company will then subtract this value from your monthly utility bill.
- Tax Credits: Unlike tax deductions, tax credits reduce, dollar-for-dollar, the amount of income tax that you owe the federal government.
- Tax Exemptions: Tax exemptions may come in two forms. First, there is sales tax exemption, 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 house.
- Rebates: Solar rebates may be offered by your local utility company, or by your state or county. These rebates are essentially partial refunds that are applied after your purchase of a solar system and before tax credits are calculated.
Federal Solar Incentives
Federal solar incentives are likely to be the first thing that comes to mind when thinking about solar incentives. The solar incentive that you're most likely to have heard of is the Federal Solar Investment Tax Credit (ITC), which provides a credit on your taxes equal to a specified percentage of your solar system's cost.
The ITC originally covered 30% of the total cost of solar panel installation, and has fluctuated slightly over time between 26-30%. The percentage you qualify for will depend on when your solar system was installed. The total cost of installation includes the panels themselves as well as the cost of labor, accessories and equipment. There is no maximum claim amount. The ITC can be applied to solar panels installed after January 1, 2006, on your primary or secondary residence. The residence must be owned by you and in the United States.
To best understand how the ITC may apply to your situation, contact your local Centennial solar panel installer and request more information.
In August 2022, the ITC (now called 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, it will also be easier to qualify for credits for energy storage systems under this new program.

State & Local Solar Incentives
Some solar incentives are often also provided by state and local governments. Similar to federal incentives, these might include tax credits, rebates and more. Certain incentives are ongoing, while others may only be available for a limited time. These incentives may be given by the Colorado government, or by your county or municipality.

EcoWatch's Centennial, CO Solar Incentives FAQs
I already have solar panels installed. Do I qualify for any incentives?
Your best bet is to talk to a representative from the company that installed your solar system – or get in touch with a local Centennial solar installer — to better understand which incentives you may 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 add solar panels to my house in Centennial?
Generally, Centennial homeowners who install solar panels save approximately $1,057.22 per year, or approximately $20,087.17 over 20 years after they make the switch.
How long until the federal solar tax credit ends?
The federal solar tax credit, formerly known as the ITC and now named the Clean Energy Credit, is scheduled 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 apply for incentives both towards the initial cost of solar panels, and later as reimbursement?
Yes, you can receive both tax credits and rebates towards the cost of your solar panels. Depending on precisely which incentives you are receiving, they may apply in a different order. Make sure that you talk to your solar installer or a local tax professional to ensure that you are claiming incentives correctly and getting the most money possible.
What if I add a solar system to a rental property, vacation home or commercial property? Will I still qualify for incentives?
While we recommend talking to your local solar installer and/or tax professional to best understand what solar incentives apply to you, many incentives will apply to a second home, so long as that home is in the United States and owned by you. There may be other incentives available specifically for commercial properties, depending on the details.
