Solar incentives are meant to help mitigate the cost of installing solar panels on your home. This category of financial incentives is intended to encourage more people to make the switch to renewable energy. Various types of incentives, such as cash back, discounts or credit towards your monthly utility bill, might be available to you. Certain incentives may be offered by the state of Colorado, by your utility company or by county or municipality, while other incentives are federal. Types of solar incentives might include:

  • Net Metering: Don't forget to talk to your Longmont utility company about signing a net metering contract. This will allow you to get a credit towards your monthly utility bill for the value of excess energy your solar panels generate. You may receive either a dollar-for-dollar credit or a percentage of the value.
  • Rebates: A rebate is a partial refund credited to your account after you've paid for your solar system. These might be offered by your local utility company, your county or your state. The rebates are usually applied before calculating tax credits.
  • 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 ignore the value that solar panels add when you are calculating property taxes on your house.
  • Tax Credits: Unlike tax deductions, tax credits reduce, dollar-for-dollar, the amount of income tax that you owe the federal government.

Federal Solar Incentives

Federal solar incentives are probably the first thing that comes to mind when thinking about solar incentives. An incentive that most people are likely to be familiar with is the Federal Solar Investment Tax Credit (ITC). This incentive is a tax credit for a certain percentage of your solar system's cost.

The ITC can be credited towards the value of solar panels installed on your primary or secondary residence in the United States. The solar panels must have been installed after January 1, 2006 on a property you own for you to claim the credit. Originally, the ITC covered 30% of all costs (panels, equipment, accessories and labor), although the amount has fluctuated 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.

To better understand exactly how much the ITC could save you, get in touch with your local Longmont solar panel installer.

In August 2022, the ITC (now called the Clean Energy Credit) was bolstered by the passing of the Inflation Reduction Act. Homeowners can now receive a credit equal to 30% of the total solar system installation costs for projects that began after January 1, 2022 and will be finished by the end of 2032. The credit percentage will then decrease annually until the Clean Energy Credit expires in 2035. Beginning in 2023, it will also be easier to get credits for energy storage systems with the new act.

More information about the new Inflation Reduction Act can be found here. To fully understand how the new Clean Energy Credit applies to you, reach out to your local Longmont solar installation expert.

State & Local Solar Incentives

There are more than just federal solar incentives; tax credits, rebates and more may be offered at the local or state level. Incentives may be given by your county or municipality, or by the state of Colorado. Some incentives might only be available for a limited time, while others are ongoing.

Next Steps for Installing Solar in Longmont

The large number of available solar incentives has enormously increased the adoption of solar energy nationwide over the past 15 years. You might qualify for solar incentives from the Colorado government, the federal government or your local utility company. Speaking with your local Longmont solar panel installation expert is an excellent first step towards making sure you get all the incentives you qualify for when you switch to solar energy.

EcoWatch's Longmont, CO Solar Incentives FAQs

If I already have a solar system installed on my house, can I still claim incentives?

If your solar panels were installed after January 1, 2022, you may qualify for the newly increased 30% tax credit under the Inflation Reduction Act. If your system was installed between 2006 and 2021, you might qualify for a tax credit between 26% and 30%, depending on the date of installation. Talking to the company that installed your solar system, or any local Longmont solar installer, can help you understand what incentives you might want to apply for.

How much can I save annually on my electric bill if I install solar panels on my Longmont home?

On average, homeowners in Longmont who install solar panels save approximately $976.62 per year, or approximately $18,555.71 over 20 years after they make the switch.

How long until the federal solar tax credit ends?

The Clean Energy Credit (previously called the federal solar tax credit, or ITC), is scheduled 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 apply for incentives both towards the up-front cost of solar panels, and later as reimbursement?

The order your incentives will be applied in might vary depending on which incentives you receive but in most cases yes, you can receive multiple types of incentives for your solar project. Check with your solar installer or a local tax professional to confirm you are claiming all of the incentives you qualify for and applying them in the correct order.
