Federal Residential Renewable Energy Tax Credit
Source: https://www.dsireusa.org/
Solar incentives encourage people to switch to renewable energy by offering incentives meant to lower the financial burden of solar panel installation and use. You may be eligible for various types of incentives, including discounts, cash back or monthly utility bill credits, depending on your situation. Some incentives come from your specific utility company, county or municipality, some from the Colorado government and others from the federal government. Some solar incentives you might qualify for are:
- Net Metering: Net metering factors in once your solar panels are up and running. If you've signed a net metering agreement with your Castle Rock utility company, it will subtract the value of the excess energy produced by your solar system from your monthly utility bill. In some areas, this credit is dollar-for-dollar, while in others you may receive a refund equivalent to a percentage of the value.
- Rebates: A rebate is a partial refund after the purchase of your solar system. Rebates may be offered by your local utility company, your county or your state. The cash back that you get from the rebates is normally applied before tax credits are calculated.
- Tax Credits: These credits are dollar-for-dollar reductions (not deductions) in how much in taxes you owe the government.
- Tax Exemptions: Your solar system may qualify for both sales tax and property tax exemptions. Sales tax exemptions are applied at the time of purchase. Property tax exemptions let you exclude the value added by your solar panels when calculating property taxes on your home.

Federal Solar Incentives
When thinking about solar incentives, you likely think of federal incentives first. A federal incentive many people are probably familiar with is the Federal Solar Investment Tax Credit (ITC). This incentive is a tax credit for a predetermined percentage of your solar system's cost.
The ITC originally covered 30% of the cost of installing a solar system, 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 cost of installation includes the panels themselves as well as the cost of accessories, labor and equipment. There is no maximum claim amount. The ITC applies 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 find out exactly how much money the ITC could save you, get in touch with your local Castle Rock solar panel installer.
The ITC was both renewed and expanded by the passage of the Inflation Reduction Act in August 2022. It's also now called the Clean Energy Credit. For solar systems installed between January 1, 2022 and December 31, 2032, homeowners may be eligible for a credit for 30% of the total cost. This percentage will decrease annually after 2032 until the Clean Energy Credit ends in 2035. The program expansion also makes claiming credit for energy storage systems easier than ever before, beginning in 2023.
More information about the new Inflation Reduction Act can be found here. Your local Castle Rock solar panel installation expert is the best person to answer your questions regarding the new Clean Energy Credit and how it may apply to you.
State & Local Solar Incentives
Some solar incentives may be provided by state and local governments. As with federal incentives, these might include rebates, tax credits and more. Certain incentives are ongoing, while others might only be available for a limited time. These incentives may be offered by your county or municipality, or by the Colorado government.

EcoWatch's Castle Rock, CO Solar Incentives FAQs
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 better understand what solar incentives apply to you, many incentives can be claimed on a second home, as long as it is in the United States and owned by you. There may be additional incentives available for commercial properties specifically, depending on the details.
If I already have a solar system installed on my house, can I still claim incentives?
Your best bet is to talk to a representative from the company that installed your solar system — or call a local Castle Rock solar installer — to clarify which incentives you may 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. Systems installed between 2006 and 2021 may qualify for a tax credit of 26-30%.

What are some environmental benefits of installing solar panels on my house?
Solar energy is a renewable energy source — by switching where you get your energy, you help lessen the strain on our planet's resources. A solar system can also lower your home's CO2 emissions by 500 pounds annually, or roughly 11,000 pounds over 20 years.
Can I use a combination of multiple types of renewable energy to power my home?
Yes, you can employ multiple types of renewable energy to power your home — for example, a combination of solar and wind power. You can also use both renewable energy sources and a backup source of non-renewable energy. You should discuss your proposed plan with your local Castle Rock solar panel installer, to make sure you know what you'll need and what types of incentives you may or may not qualify for.
