The phrase "solar incentives" generally refers to financial incentives that are in place to encourage the adoption and use renewable energy by making installing and using solar panels more affordable. Solar incentives might include upfront discounts, cash back or credit towards your monthly utility bill. Some incentives are given by the federal government, some by the state of Colorado and some by your utility company, county or municipality. You might qualify for any of the following types of solar incentives:

  • Tax Credits: Unlike tax deductions, tax credits reduce, dollar-for-dollar, the amount of income tax that you owe the federal government.
  • Rebates: Solar rebates can be offered by your state or county, or by your local utility company. These rebates work as partial refunds that are applied after your purchase of solar panels and before tax credits are calculated.
  • Net Metering: Net metering factors in after your solar panels are up and running. If you have a net metering agreement with your Denver 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 areas, this credit is dollar-for-dollar, while in others you may make back a percentage of the value.
  • Tax Exemptions: Your solar system may qualify for exemptions on both sales and property tax. Sales tax exemptions are effective at the time of purchase. Property tax exemptions let you ignore the added value of the solar panels when calculating property taxes on your house.

Federal Solar Incentives

When someone says "solar incentives," you likely think of federal incentives first. 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 specified percentage of the money you spend on solar panels for your home.

The ITC can be credited towards the value of solar panels installed on your primary or secondary residence in the United States. The solar panels must have been installed on a property you own after January 1, 2006, for you to claim the credit. The ITC initially covered 30% of all installation costs (panels, accessories, equipment and labor), although the amount has fluctuated over the last few years between 26-30%. The installation date of your solar system will determine what percentage you are eligible for. There is no cap on the amount you can claim.

Contacting your local Denver solar panel installation expert is the best way to learn more about how the ITC may apply to your situation.

The Inflation Reduction Act, passed in August 2022, made some changes to the ITC (as well as retitling it the Clean Energy Credit). The new Clean Energy Credit is valid until 2035. Homeowners can now receive a 30% credit for solar systems installed between January 1, 2022, and December 31, 2032. This new credit will then see a slight annual decrease until its expiration. Beginning in 2023, it will also be easier to get credits for energy storage systems under the new laws.

More information about the new Inflation Reduction Act can be found here. The best way to fully understand how the new Clean Energy Credit might apply to you is to talk with your local Denver solar panel company.

State & Local Solar Incentives

Some solar incentives are often also offered at the local or state level. Similar to federal incentives, these may include rebates, tax credits and more. These incentives — which may be given by the state of Colorado, or by your county or municipality — could be offered on an ongoing basis, or for only a limited time.

Next Steps for Installing Solar in Denver

You can apply for solar incentives from the Colorado government and the federal government, as well as from your local utility company. The growing availability of solar initiatives over the last 15 years has helped increase nationwide solar energy use enormously. Speaking with your local Denver solar panel installer is the best first step towards getting all the incentives you qualify for when you switch to solar energy.

EcoWatch's Denver, CO Solar Incentives FAQs

My home already has solar panels. Are there any incentives that I qualify for?

Your best bet is to talk to the company that installed your solar panels – or reach out to a local Denver 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 recently increased 30% tax credit under the Inflation Reduction Act. Solar systems installed between 2006 and 2021 may qualify for a tax credit of 26-30%.

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

Once you add solar panels to your house in Denver, you can expect to save around $998.12 per year, or around $18,964.25 over the next 20 years.

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 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 receive any incentives when I add solar panels to a vacation home, rental property or commercial property?

While we recommend getting in touch with your local solar installer and/or tax professional to fully understand what solar incentives apply to you, many apply to a second home, as long as it is in the United States and owned by you. There may be other incentives available specifically for commercial properties, depending on the specifics.
