Federal Residential Renewable Energy Tax Credit

The phrase "solar incentives" covers a wide range of financial incentives put in place to make installing and using solar panels more affordable. This is done to encourage people to switch to renewable energy. You may qualify for several kinds of incentives, such as discounts, cash back or credit towards your monthly utility bill, 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:
- Tax Credits: These credits are dollar-for-dollar reductions (not deductions) in how much in taxes you owe the federal government.
- Tax Exemptions: These might 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 home. They may also include exemptions on sales tax at the time of purchase.
- Net Metering: Net metering factors in after your solar panels are up and running. If you've signed a net metering agreement with your Longmont 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 places, this credit is dollar-for-dollar, while in other places you might receive a refund equivalent to a percentage of the value.
- Rebates: A solar rebate is a partial refund credited to your account after you've paid for your solar panels. Rebates may be offered by your local utility company, your state or your county. The discount that rebates offer is normally applied to the price of solar panels before tax credits are calculated.
Federal Solar Incentives
When thinking about solar incentives, federal incentives may be the first thing that comes to mind. The solar incentive that you may be most familiar with is the Federal Solar Investment Tax Credit (ITC), which gives you a credit on your taxes equal to a predetermined percentage of your solar system's cost.
The ITC originally covered 30% of the cost of installing solar panels, and has fluctuated slightly over the years 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 in the United States and owned by you.
Contacting your local Longmont solar panel installer is the best way to understand how the ITC could apply to your situation.
The Inflation Reduction Act, passed in August 2022, added more provisions to the ITC (as well as renaming it to the Clean Energy Credit). The new Clean Energy Credit extends until 2035. Homeowners are now eligible for a 30% credit for solar systems that began installation after January 1, 2022, and are completed by the end of 2032. This new credit will then see a slight annual decrease until the date of expiration. The expansion also makes claiming credit for energy storage systems easier than ever before, beginning in 2023.
Click here to learn more about the new Inflation Reduction Act. The best way to learn more about how the new Clean Energy Credit will apply to you is to talk with your local Longmont solar panel company.
State & Local Solar Incentives
Some solar incentives are often also provided at the state and local level. Similar to federal incentives, these can include rebates, tax credits and more. Certain incentives are ongoing, while others are offered for only a limited time. Your local incentives might come from your county or municipality, or from the Colorado government.
Next Steps for Installing Solar in Longmont

EcoWatch's Longmont, CO Solar Incentives FAQs
If I already have a solar system installed on my house, can I still claim incentives?
An excellent idea would be to talk to someone from the company that installed your solar system – or call a local Longmont solar installer — to learn about which incentives you might qualify for. If your solar panels were installed after January 1, 2022, you likely qualify for the newly 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%.

How long until the federal solar tax credit ends?
The federal solar tax credit, formerly called the ITC and now named the Clean Energy Credit, is scheduled 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.
If I trade in my appliances for ones that can utilize solar energy, are there credits that 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.
