Solar incentives are meant to help mitigate the cost of installing solar panels on your home. These financial incentives are designed to encourage more Americans to convert their home partially or fully to renewable energy. Different types of incentives, like discounts, cash back or credit towards your monthly utility bill, may be available to you. Certain incentives may be handled by the state of Idaho, by your utility company or by county or municipality, while other incentives are federal. You might qualify for any of the following types of solar incentives:

  • Tax Credits: Tax credits are dollar-for-dollar reductions (not deductions) in the amount of tax that you owe the federal government.
  • Net Metering: Make sure you talk with your Caldwell utility company about signing a net metering agreement. This will allow you to get a credit towards your monthly utility bill for the value of excess energy your solar panels generate. You might receive either a dollar-for-dollar credit or a percentage of the value.
  • Tax Exemptions: Tax exemptions may come in one of two forms. First, there is sales tax exemption, applied at the time you purchase your 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.
  • Rebates: A rebate is a partial refund given after you've purchased your solar panels. These might be offered by your local utility company, your county or your state. The discount that rebates offer is normally applied to the price of solar panels before tax credits are calculated.

Federal Solar Incentives

When you hear the term "solar incentives," federal incentives may be the first thing that comes to mind. The solar incentive that you're most familiar with is probably the Federal Solar Investment Tax Credit (ITC), which provides a credit on your taxes equal to a percentage of your solar system's cost.

The ITC can be applied to solar panels 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 originally paid out 30% of all costs (panels, labor, equipment and accessories), although the 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.

Wondering how the ITC applies to your specific situation? Get in touch with your local Caldwell solar panel installation expert to get more information.

In August 2022, the ITC (now titled the Clean Energy Credit) was expanded and extended by the passage of the Inflation Reduction Act. The Clean Energy Credit bolsters the current credit, increasing it up to 30% for solar installation projects started after January 1, 2022, and completed by the end of 2032. After 2032, the percentage will see a slight decrease annually until the program expires in 2035. Beginning in 2023, it will also be easier to qualify for credits for energy storage systems under the new laws.

More information about the new Inflation Reduction Act can be found here. To best understand how the new Clean Energy Credit applies to you, talk to your local Caldwell solar installers.

State & Local Solar Incentives

Some solar incentives may be offered at the local or state level. Like with federal incentives, these can include rebates, tax credits and more. Incentives might be provided by the state of Idaho, or by your county or municipality. Certain incentives might only be available for a limited time, while others are ongoing.

Next Steps for Installing Solar in Caldwell

Solar incentives can be provided by your local utility company, the Idaho government or the federal government. The variety of solar incentives available has helped nationwide use of solar energy increase greatly in the last 15 years. Speaking with your local Caldwell solar panel installation company is a great first step towards getting all the incentives you qualify for when you switch to solar energy.

  1. a new solar system
  2. installed on a property that you own
  3. within the U.S.

I already have solar panels installed. Does my system qualify for any 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 may qualify for a tax credit between 26% and 30%, depending on the year it was installed. Talking to the company that installed your solar system, or any local Caldwell solar installer, can help you learn more about what incentives you can apply for.

How much can I save annually on my electric bill if I add solar panels to my Caldwell home?

Once you add solar panels to your home in Caldwell, you can expect to save approximately $846.41 per year, or approximately $16,928.12 over the next 20 years.

How long until the federal solar tax credit ends?

The federal solar tax credit, formerly known as the ITC and now named the Clean Energy Credit, is set to end on January 1, 2035. The current 30% credit will end in 2032, replaced by a 26% credit in 2033 and a 22% credit in 2034.
