Solar incentives are designed to make renewable energy usage more affordable through financial incentives for those who install solar panels on their homes. Various types of incentives, including cash back, discounts or credit towards your monthly utility bill, might be available to you. Certain incentives may be handled by the Colorado government, by your utility company or by county or municipality, while other incentives are federal. You might qualify for any of the following types of solar incentives:

  • Rebates: Your solar installer might help you claim a rebate, or partial refund of your purchase, for your solar panels. States or counties will also offer limited-time rebates at various times. The value of a rebate will usually be deducted from your total price before any tax credits are calculated.
  • Tax Credits: Tax credits are dollar-for-dollar reductions in the amount of income tax that you owe the federal government. (This is different from a tax deduction.)
  • Net Metering: Make sure you speak with your Windsor utility company about signing a net metering agreement. This will allow you to receive credit towards your utility bill every month for the value of excess energy your solar panels generate. You could receive either a dollar-for-dollar credit or a percentage of the value.
  • Tax Exemptions: These may come in the form of property tax exemptions, which can let you exclude the value added by your solar panels when paying property tax on your house. You may also qualify for an exemption on sales tax at the time of purchase.

Federal Solar Incentives

Federal incentives are the kind of incentives that you are most likely to have some knowledge of. An incentive many people are probably familiar with is the Federal Solar Investment Tax Credit (ITC). This incentive is a tax credit for a specific percentage of the cost of your solar system.

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

Contacting your local Windsor solar panel installer is the best way to understand how the ITC applies to your situation.

The Inflation Reduction Act, passed in August 2022, expanded and extended the ITC (as well as retitling it the Clean Energy Credit). The new Clean Energy Credit extends until 2035. American homeowners are now eligible for a 30% credit for solar systems installed between January 1, 2022, and December 31, 2032. The credit will then decrease annually until its expiration. Starting in 2023, the expansion to the program will also make claiming credit for energy storage systems easier than ever before.

State & Local Solar Incentives

In addition to federal solar incentives, there are often also state ones. Rebates, tax credits and more might be available at a more local level. These incentives might be given out by the Colorado government, or by your county or municipality. Some are available for a limited time, while others are ongoing.

Next Steps for Installing Solar in Windsor

You can qualify for 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 solar adoption nationwide. When you're ready to switch over to solar energy, calling your local Windsor solar panel installation expert is a great first step.

EcoWatch's Windsor, CO Solar Incentives FAQs

How can I find out if I qualify for specific solar incentives?

It's a good idea to talk to your local Windsor solar installer to get an understanding of which incentives your project may qualify for. Typically, solar incentives apply to new solar systems installed on 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.

If I installed solar panels on my house a few years ago, can I still claim incentives?

An excellent idea would be to talk to a representative from the company that installed your solar system – or call a local Windsor solar installer — to learn about which incentives you may qualify for. If your solar panels were installed after January 1, 2022, you likely qualify for the recently increased 30% tax credit under the Inflation Reduction Act. Solar panels installed between 2006 and 2021 may qualify for a tax credit of 26-30%.

If I change out my appliances for ones that utilize solar energy, are there incentives that I can claim?
