The term "solar incentives" generally refers to financial incentives designed to encourage the adoption and use renewable energy by making installing and using solar panels more affordable. These incentives can include cash back, upfront discounts or monthly credits towards your utility bill. Some incentives are handled by the federal government, some by the Colorado government and some by your utility company, county or municipality. Some solar incentives you might qualify for are:

  • Tax Exemptions: Your solar panel system may qualify for exemptions on both sales and property tax. Sales tax exemptions come into effect at the time of purchase. Property tax exemptions let you exclude the added value of the solar panels when calculating property taxes on your house.
  • Rebates: Some solar companies will help you claim a rebate, or partial refund of your purchase, for your solar panels. Counties or states will also sometimes offer limited-time rebates. Any rebates you receive will usually be deducted from the total price before any tax credits are calculated.
  • Net Metering: Don't forget to talk with your Louisville utility company about signing a net metering contract. This allows you to get a credit towards your utility bill every month for the value of excess energy generated by your solar panels. You might receive either a dollar-for-dollar credit or a percentage of the value.
  • Tax Credits: Tax credits decrease, dollar-for-dollar, the amount of income tax you owe the government. Tax credits differ from tax deductions.

Federal Solar Incentives

Federal incentives are the type of incentives that you are most likely to have some knowledge of. The solar incentive that you're most likely to have heard of is the Federal Solar Investment Tax Credit (ITC), which provides a credit on your taxes equal to a certain percentage of the cost of your solar system.

The ITC applies to a solar system installed on your primary or secondary residence in the United States. The solar panels must have been installed on a property you own after January 1, 2006, for you to claim the credit. The ITC initially covered 30% of all system installation costs (panels, accessories, labor and equipment), although the covered amount has fluctuated slightly over the last few years between 26-30%. The installation date of your solar system will determine what percentage you are eligible for. There is no cap on the amount you can claim.

Your local Louisville solar panel installer can offer more information about the ITC and how it applies to your situation.

In August 2022, the ITC (now referred to as the Clean Energy Credit) was expanded and extended by the passing of the Inflation Reduction Act. The Clean Energy Credit is valid until 2035. Solar installation projects started after January 1, 2022, and completed by the end of 2032 may qualify for a 30% tax credit; the amount will decrease slightly on a yearly basis until the current program ends. Starting in 2023, it will also be easier to get credits for energy storage systems under this new program.

State & Local Solar Incentives

Federal solar incentives are not your only option; rebates, tax credits and more might also be offered at the local or state level. Some incentives are offered for only a limited time, while others are ongoing. Local solar incentives could come from the Colorado government, or from your specific county or municipality.

Next Steps for Installing Solar in Louisville

You can apply for and receive solar incentives from the federal government and the Colorado government, as well as from your local utility company. This increase in availability of solar initiatives over the last 15 years has helped greatly increase nationwide adoption of solar energy. It is a good idea to talk to your local Louisville solar installation expert for more information about these incentives and to be sure that you're getting the largest number possible for your solar panels.

EcoWatch's Louisville, CO Solar Incentives FAQs

How do I know if I qualify for solar incentives?

It's a good idea to talk to your local Louisville solar installer for a better understanding of which incentives your project will qualify for. In most cases, solar incentives apply to new solar systems installed on property you own (in the U.S.) between the dates specified by the incentive. Some incentives, like those given by the state of Colorado, may have other requirements.

What are the environmental benefits of switching to solar energy?

You can lower your carbon footprint by 500 pounds of CO2 annually when you switch to solar panels. This adds up to around 11,000 pounds over 20 years. Solar is also a renewable energy source, meaning that making the switch lessens the drain on our planet's resources.

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

With the passage of the new Inflation Reduction Act, there are several new financial incentives that are available when you make eco-friendly improvements to your home. More details about these incentives, including information about incentives for purchasing new appliances, can be found here.
