Solar incentives are intended to make renewable energy usage more affordable through financial incentives to help people install solar panels on their homes. The incentives may include cash back, upfront discounts or monthly credits towards your utility bill. Some incentives are offered by the federal government, some by the Indiana government and some by your specific utility company, county or municipality. Types of solar incentives might include:

  • Tax Exemptions: Tax exemptions can 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 added value of your solar system when calculating property tax for your house.
  • Rebates: Some solar companies will help you claim a rebate, or partial refund after purchase, for your solar panels. Counties or states will also sometimes offer limited-time rebates. Any rebates you receive will usually come off the total price before tax credits are calculated.
  • Tax Credits: Tax credits are dollar-for-dollar reductions in the amount of income tax that you owe the federal government. (This is different from a tax deduction.)
  • Net Metering: Be sure to speak with your Indianapolis 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 your solar panels generate. You may receive either a dollar-for-dollar credit or a percentage of the value.

Federal Solar Incentives

When thinking about solar incentives, you likely think of federal incentives first. The Federal Solar Investment Tax Credit, or ITC, is likely the most well-known federal solar incentive. The ITC provides a tax credit for a specific percentage of your solar system's cost.

The ITC originally covered 30% of the cost of installing solar panels, although that number has fluctuated slightly over time between 26-30%. The percentage you qualify for will depend on when your solar system was installed. The total installation cost includes the panels themselves as well as the cost of equipment, labor and accessories. There is no maximum amount you can claim. The ITC can be applied to solar systems installed after January 1, 2006 on your primary or secondary residence. The residence must be in the United States and owned by you.

Have questions about how the ITC applies to your specific situation? Get in touch with your local Indianapolis solar panel installation expert to get more information.

In August 2022, the ITC (now called the Clean Energy Credit) was bolstered by the passing of the Inflation Reduction Act. The new Clean Energy Credit now runs until 2035. You can now receive a 30% credit for solar systems installed between 2022 and 2032. The total credit will then see a slight annual decrease until it expires. The program expansion also makes it easier to get credit for energy storage systems, starting in 2023.

State & Local Solar Incentives

Federal solar incentives are not your only option; rebates, tax credits and more might also be offered at the local or state level. These incentives — which may be given by your county or municipality, or by the state of Indiana — might be offered on an ongoing basis, or for only a limited time.

EcoWatch's Indianapolis, IN Solar Incentives FAQs

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

Typically, solar incentives apply to:

  1. a new solar panel 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 given out by the Indiana government or by your county/municipality, sometimes have additional qualifications. Speak with your local Indianapolis solar installer to find out what incentives your project will qualify for.

If I installed solar panels on my house a few years ago, can I still claim incentives?

Your best bet is to talk to a representative from the company that installed your solar system — or reach out to a local Indianapolis solar installer — to clarify which incentives you might qualify for. If your solar panels were installed after January 1, 2022, you likely qualify for the recently increased 30% tax credit under the Inflation Reduction Act. Solar systems installed between 2006 and 2021 may qualify for a tax credit of 26-30%.

What are the environmental benefits of switching to solar energy?

Solar energy is renewable — by switching where you get your energy, you can help reduce the strain on our planet's resources. You can also lower the CO2 emissions from your home by 450 pounds annually, or roughly 9,000 pounds over 20 years.

Can I apply for incentives both towards the initial cost of solar panels, and later as reimbursement?

Yes, you can receive both rebates and tax credits towards the cost of your solar panels. Depending on precisely which incentives you are applying for, they may apply in a different order. Make sure that you speak with your solar installer or a local tax professional to ensure 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 employ multiple types of renewable energy to power your home — for example, a combination of wind and solar. You can also combine renewable energy generation with a non-renewable backup source of energy. Make sure that you discuss the details of your plan with your local Indianapolis solar installation expert, to make sure you know what you'll need and what types of incentives you may or may not qualify for.
