The term "solar incentives" generally refers to financial incentives put in place by solar companies and the government to encourage increased use of renewable energy by making installing and using solar panels more affordable. Incentives might include things like discounts, cash back or credit towards your monthly utility bill. Some incentives are offered by the federal government, while others are provided by the state of Wisconsin or your specific utility company, county or municipality. Types of solar incentives might include:

  • Rebates: Solar rebates might be offered by your local utility company, or by your state or county. These rebates work as partial refunds that are applied after your purchase of solar panels and before tax credits are calculated.
  • Tax Exemptions: These may come in the form of property tax exemptions, which let you exclude the value of your solar system when calculating the taxes you pay on your home. They may also include exemptions on sales tax at the time of purchase.
  • Tax Credits: Unlike tax deductions, tax credits are dollar-for-dollar reductions in the amount of income tax that you owe the government.
  • Net Metering: Net metering becomes relevant after your solar system is up and running. If you have a net metering agreement with your Summit utility company, it will subtract the value of the excess energy produced by your solar system from your monthly utility bill. In some places, this credit is dollar-for-dollar, while in others you might make back a percentage of the value.

Federal Solar Incentives

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

The ITC applies to the value of 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. Initially, the ITC applied to 30% of all system costs (panels, accessories, equipment and labor), although this amount has fluctuated slightly over the last few years between 26-30%. The amount you qualify for will depend on when your solar system was installed. There is no cap on the claim amount.

Talking to your local Summit solar panel installation expert is the best way to learn more about how the ITC applies to you.

In August 2022, the ITC (now titled the Clean Energy Credit) was expanded and extended by the passing of the Inflation Reduction Act. Homeowners can now receive a credit of 30% of the total costs of solar system installation for projects started after January 1, 2022 and completed before the end of 2032. This percentage will then decrease annually until the Clean Energy Credit ends in 2035. Starting in 2023, it will also be easier to claim credits for energy storage systems under the new laws.

More information about the new Inflation Reduction Act can be found here. The easiest way to learn more about how the new Clean Energy Credit might apply to you is to speak with your local Summit solar panel installation expert directly.

State & Local Solar Incentives

In addition to those provided at the federal level, there are often also state solar incentives. Tax credits, rebates and more can be offered at a more local level. Incentives may be handled by the state of Wisconsin, or by your county or municipality. Some incentives might only be available for a limited time, while others are ongoing.

Next Steps for Installing Solar in Summit

There are many types of solar incentives: those provided by local utility companies, those provided by the federal government and those provided by the Wisconsin government, to name a few. The use of solar energy has grown enormously in the last 15 years, partially thanks to these incentives. Getting in touch with your local Summit solar panel installation company is a great first step towards getting all the incentives you qualify for when you switch to solar energy.

EcoWatch's Summit, WI Solar Incentives FAQs

What are some of the environmental benefits of switching to solar energy?

Solar energy is a renewable energy source — by changing where you get your energy, you can help lessen the strain on our planet's resources. A solar system can also reduce your home's CO2 emissions by 450 pounds yearly, or around 9,000 pounds in 20 years.

When does the federal solar tax credit end?

The Clean Energy Credit (previously called the federal solar tax credit, or ITC), currently ends on January 1, 2035. Currently set at 30%, the credit will drop to 26% in 2033 and to 22% in 2034.

If I switch my appliances out for ones that can utilize solar energy, are there any incentives that I can claim?

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

Can I receive incentives both towards the up-front cost of solar panels, and later as reimbursement?

Yes, you can claim both tax credits and rebates towards the cost of your solar panels. Depending on which incentives you are eligible for, they may apply in a different order. Be sure to speak with your solar installer or a local tax professional to verify that you are claiming the correct incentives and getting the most money possible.

Can I use solar and another type of renewable energy in combination to power my home?

Yes, you can utilize multiple types of renewable energy to power your home, such as a combination of solar and geothermal. You can also combine renewable energy generation with a backup source of non-renewable energy. Make sure that you discuss the details of your plan with your local Summit solar installation expert, to get an understanding of what will be needed and what types of incentives you may or may not qualify for.
