Solar incentives are designed to make renewable energy usage more affordable via financial incentives for individuals who install solar panels on their homes. You may be eligible for various types of incentives, such as cash back, discounts or monthly utility bill credits, depending on your situation. Certain incentives come from your specific utility company, county or municipality, some from the Colorado government and others from the federal government. Categories of solar incentives include:

  • Rebates: A rebate is a partial refund after the purchase of your solar system. Rebates might be offered by your local utility company, your county or your state. The discount that rebates offer is normally applied to the price of solar panels before calculating tax credits.
  • Net Metering: You may be able to sign a net metering agreement with your Denver utility company. This agreement 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 Exemptions: These may come in the form of property tax exemptions, which allow you to ignore the value of your solar system when paying property tax on your house. They may also include exemptions on sales tax at the time of purchase.
  • Tax Credits: Tax credits decrease, dollar-for-dollar, the amount of income tax you owe the government. These are different from tax deductions.

Federal Solar Incentives

Federal incentives are the type of incentives that you are most likely to have heard of. The Federal Solar Investment Tax Credit, or ITC, is likely the most well-known federal solar incentive. The ITC offers a tax credit for a specific percentage of your solar system's cost.

The ITC applies towards solar systems installed after January 1, 2006 and under this program you can deduct from your taxes a percentage of the total cost of solar panels, labor, accessories and equipment. You can receive this credit for solar panels installed on a primary or secondary residence that you own in the United States. Originally, you could claim 30% of the total cost, although certain projects may qualify for only 26%, depending on the details. There is no maximum claim amount.

Wondering how the ITC applies to your specific situation? Get in touch with your local Denver solar panel installation expert to get more information.

In August 2022, the Inflation Reduction Act expanded and extended the ITC, now titled the Clean Energy Credit. The Clean Energy Credit is valid until 2035. Any solar installation project that is completed between January 1, 2022 and December 31, 2032 may qualify for a 30% tax credit. This amount will be decreased slightly each year until the current program ends. The program expansion also makes credits for energy storage systems even easier to claim, starting in 2023.

State & Local Solar Incentives

Not all solar incentives are federal; rebates, tax credits and more might also be offered at the local or state level. Some incentives are ongoing, while others are only available for a limited time. Incentives might be given by your county or municipality, or by the Colorado government.

Next Steps for Installing Solar in Denver

EcoWatch's Denver, CO Solar Incentives FAQs

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

While we recommend speaking with your local solar installer and/or tax professional to best understand what solar incentives apply to you, many will apply to a second home, provided that it is in the United States and owned by you. There may be additional incentives available specifically for commercial properties, depending on the specifics.

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

It's a good idea to talk to your local Denver solar installer to get an 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 given by the state of Colorado, may have other requirements.

When does the federal solar tax credit end?

The Clean Energy Credit (previously called the federal solar tax credit, or the ITC), is slated to end on January 1, 2035. Currently set at 30%, the credit will drop to 26% in 2033 and to 22% in 2034.

If I trade in my appliances for ones that can use solar energy, are there credits I can claim?

The new Inflation Reduction Act creates a variety of new financial incentives to encourage you to make eco-friendly improvements to your home. More details about these incentives, including information about incentives for purchasing new appliances, can be found here.

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

You can use multiple types of renewable energy, or a combination of renewable and non-renewable energy, to power your home. Be sure to go over your ideas with your local Denver solar installer. They can help you with the plan for your project and give you an understanding of various incentives that you will or won't qualify for.
