Solar incentives are meant to help mitigate the cost of installing solar panels on your home. This category of financial incentives is designed to encourage more homeowners to make the switch to renewable energy. Various types of incentives, such as discounts, cash back or monthly utility bill credits, may be available to you. Certain incentives may be provided via the Indiana government, by your utility company or by county or municipality, while others are federal. You might qualify for any of the following types of solar incentives:

  • Tax Exemptions: Your solar panel system could qualify for both sales tax and property tax exemptions. Sales tax exemptions are effective at the time of purchase. Property tax exemptions let you exclude the value added by your solar panels when calculating property taxes on your house.
  • Rebates: A solar rebate is a partial refund credited to your account after you've paid for your solar panels. Rebates could be offered by your local utility company, your state or your county. The discount that rebates offer is normally applied to the price of solar panels before tax credits are calculated.
  • Tax Credits: Unlike tax deductions, tax credits reduce, dollar-for-dollar, the amount of income tax that you owe the federal government.
  • Net Metering: Don't forget to talk with your Plainfield 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 may receive either a dollar-for-dollar credit or a percentage of the value.

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 may be most familiar with is the Federal Solar Investment Tax Credit (ITC), which gives you a credit on your taxes equal to a certain percentage of the cost of your solar system.

The ITC can be credited towards the value of solar panels installed on your primary or secondary residence in the United States. The solar system has to 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 system costs (panels, equipment, accessories and labor), although this amount has fluctuated over the 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 claim amount.

To more fully understand how the ITC could apply to your situation, reach out to your local Plainfield solar panel installation expert and ask for more information.

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. For solar systems installed between January 1, 2022, and December 31, 2032, homeowners can apply for a credit for 30% of the total cost. The percentage will then decrease annually until the Clean Energy Credit ends in 2035. Starting in 2023, the expansion to the program will also make claiming credit for energy storage systems easier than ever before.

More information about the new Inflation Reduction Act can be found here. The easiest way to understand how the new Clean Energy Credit might apply to you is to get in touch with your local Plainfield solar panel company.

State & Local Solar Incentives

There are more than just federal solar incentives; rebates, tax credits and more might also be offered at the local or state level. Certain incentives are ongoing, while others are offered for only a limited time. These local incentives might come from the Indiana government, or from your specific county or municipality.

Next Steps for Installing Solar in Plainfield

Solar energy utilization has grown tremendously in the last 15 years, partially thanks to these incentives. When you're ready to make the switch to solar energy, talking to your local Plainfield solar panel installation expert is a great first step.

EcoWatch's Plainfield, IN Solar Incentives FAQs

How do I know if I qualify for solar incentives?

In most cases, solar incentives apply to:

  1. a new solar system
  2. installed on a property that you own
  3. within the U.S.
  4. between the dates specified by a particular incentive.

Specific incentives, including those run by the Indiana government or by your county/municipality, sometimes have additional qualifications. Talk to your local Plainfield solar installer to find out what incentives your project will qualify for.

I already have solar panels installed. Do I qualify for any incentives?

You should plan to talk to a representative from the company that installed your solar panels – or speak to a local Plainfield solar installer — to learn about which incentives you might qualify for. If your system was installed after January 1, 2022, you likely qualify for the newly increased 30% tax credit under the Inflation Reduction Act. Solar panels installed between 2006 and 2021 may qualify for a tax credit of 26-30%.

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

The recently passed Inflation Reduction Act introduces several incentives that reward homeowners who make eco-friendly upgrades. Some of these incentives include tax credits and rebates for installing new electric appliances. You can find more details about these incentives here.

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

Yes, you can use multiple types of renewable energy to power your home — for example, a combination of solar and geothermal. You can also use both renewable energy sources and a non-renewable backup source of energy. You should discuss your proposed plan with your local Plainfield solar installation expert, to make sure you know what you'll need and what incentives you might or might not qualify for.
