The phrase "solar incentives" generally refers to financial incentives implemented by the government and by solar companies to encourage increased use of renewable energy by making the installation and use of solar panels more affordable. Incentives can include things like discounts, cash back or monthly utility bill credits. Some incentives are offered by the federal government, while others are provided by the state of Montana or your utility company, county or municipality. Categories of solar incentives include:

  • Net Metering: Be sure to speak with your Helena utility company about signing a net metering agreement. This allows you to receive credit towards your monthly utility bill 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 Exemptions: Tax exemptions can come in 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 ignore the added value of your solar system when paying property tax on your house.
  • Rebates: Solar rebates might be provided by your local utility company, or by your county or state. These rebates work as cash back that is applied after you purchase a solar system and before tax credits are calculated.
  • Tax Credits: Tax credits decrease, dollar-for-dollar, the amount of income tax you owe the federal government. Tax credits are different from tax deductions.

Federal Solar Incentives

When you think about solar incentives, you probably think of federal incentives first. A federal incentive many people are probably familiar with is the Federal Solar Investment Tax Credit (ITC). The ITC is a tax credit for a specified percentage of your solar system's cost.

The ITC can be applied to solar systems installed after January 1, 2006, on a primary or secondary residence that you own in the United States. Initially, the credit applied to 30% of the total cost – for panels, labor, equipment and accessories – although it may range from 26-30%, depending on when your solar system was installed. There is no cap on the amount you can claim.

To understand exactly how much money the ITC could save you, talk to your local Helena solar panel installer.

The Inflation Reduction Act, passed in August 2022, added more provisions to the ITC (as well as retitling it the Clean Energy Credit). Under the new program, solar installation projects that are completed between 2022 and 2032, may be eligible for a 30% tax credit. This credit amount will then see a slight annual decrease until the end of the current Clean Energy Credit in 2035. Starting in 2023, it will also be easier to claim credits for energy storage systems under this new program.

State & Local Solar Incentives

Some solar incentives may be provided at the state and local level. As with federal incentives, these might include tax credits, rebates and more. Certain incentives are ongoing, while others may only be available for a limited time. These incentives might be given by your county or municipality, or by the Montana government.

Next Steps for Installing Solar in Helena

There are many kinds of solar incentives: those offered by the federal government, those offered by the Montana government and those offered by local utility companies, to name a few. Solar energy use has grown tremendously in the last 15 years, partially due to these incentives. Your local Helena solar panel installer can help you learn more about which incentives you can apply for, and get you feeling good about making the change to renewable energy today.

EcoWatch's Helena, MT Solar Incentives FAQs

How do I learn if I qualify for specific solar incentives?

It's a smart idea to get in touch with your local Helena solar installer for a better understanding of which incentives your project will qualify for. Typically, 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 provided by the Montana government, might have additional requirements.

My home already has solar panels. Do I qualify for any incentives?

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

Can I use both solar and another type 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. Be sure to discuss your proposed plan with your local Helena solar installation expert, so that you understand what you'll need and what kinds of incentives you might or might not qualify for.

Can I receive any incentives when I add solar panels to a vacation home, rental property or commercial property?

While we recommend speaking with your local solar installer and/or tax professional to better understand what solar incentives apply to you, many incentives apply to a second home, provided that it is in the United States and owned by you. There may be other incentives available specifically for commercial properties, depending on the details.
