The phrase "solar incentives" refers to financial incentives put in place by solar companies and the government to encourage people to use renewable energy by making installing and using solar panels more affordable. Incentives may include things like discounts, cash back or credit on your utility bill each month. Some incentives are offered by the federal government, while others are provided by the Colorado government or by your specific utility company, county or municipality. Categories of solar incentives include:

  • Tax Exemptions: Tax exemptions can come in one of two forms. The first is sales tax exemption, applied when you purchase solar panels. The second is property tax exemption. This allows you to exclude the value added by your solar system when calculating property tax for your home.
  • Net Metering: Net metering factors in after your solar system is up and running. If you have in place a net metering agreement with your Castle Pines utility company, it 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 other places you may make back a percentage of the value.
  • Tax Credits: Tax credits reduce, dollar-for-dollar, the total amount of tax you owe the federal government. Tax credits are different from tax deductions.
  • Rebates: Solar rebates might be offered by your local utility company, or by your county or state. These rebates work as partial refunds that are applied after you purchase a solar system and before tax credits are calculated.

Federal Solar Incentives

Federal solar incentives are likely the first thing that comes to mind when you think about solar incentives. You may have heard of the Federal Solar Investment Tax Credit, or ITC. This is a tax credit equal to a specified percentage of the money you spend on your solar system.

The ITC can be applied to the total cost of solar system installation, including the panels themselves as well as accessories, equipment and labor. This credit can be claimed for panels installed after January 1, 2006 on a primary or secondary residence located in the United States that you own. Originally set at 30% of total costs, the credit has fluctuated over time, and you may qualify for different amounts depending on when your project was completed. There is no maximum amount you can claim.

Your local Castle Pines solar panel installation expert can give you more information about the ITC and how it may apply to your situation.

In August 2022, the ITC (now called the Clean Energy Credit) was bolstered by the passage of the Inflation Reduction Act. The new Clean Energy Credit now runs until 2035. Homeowners can now receive a 30% credit for solar systems that began installation on or after January 1, 2022 and will be done by December 31, 2032. The total credit will then see a slight annual decrease until it expires. Starting in 2023, the expansion to the program will also make claiming credit for energy storage systems easier than ever before.

More information about the new Inflation Reduction Act can be found here. Your local Castle Pines solar panel installation expert is the best person to answer your questions about the new Clean Energy Credit and how it may apply to you.

State & Local Solar Incentives

Tax credits, rebates and more can be claimed at multiple levels. In addition to federal solar incentives, there are often state and local ones, too. These incentives may be distributed by the Colorado government, or by your county or municipality. Some incentives may be ongoing, while others are available for a limited time.

Next Steps for Installing Solar in Castle Pines

There are many kinds of solar incentives: those provided by local utility companies, those provided by the Colorado government and those provided by the federal government, to name a few. Solar energy use has increased enormously in the last 15 years, partially due to these incentives. Getting in touch with your local Castle Pines solar panel installation company is an excellent first step towards making sure you get all the incentives you qualify for when you switch to solar energy.

EcoWatch's Castle Pines, CO Solar Incentives FAQs

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

Many solar incentives apply to a property located within the United States that you own; most secondary residences fall under this distinction. Other solar incentives may be available for commercial properties, depending on the specifics. We recommend getting in touch with your local solar installer and/or tax professional to best understand what incentives will apply to your specific situation.

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

It's a smart idea to get in touch with your local Castle Pines solar installer for a better understanding of which incentives your project may qualify for. Usually, solar incentives apply to new solar panel systems installed on property you own (in the U.S.) within a specified date range. Some incentives, like those offered by the government of Colorado, might have other requirements.

How long until the federal solar tax credit ends?

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.

Can I use 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 combine renewable energy generation with a backup source of non-renewable energy. Make sure that you discuss your plan with your local Castle Pines solar panel installer, to make sure you know what you'll need and what kinds of incentives you may or may not qualify for.
