Federal solar tax credit

Indiana homeowners who invest in solar can save 30% on their solar panel installation through the federal solar tax credit.

The average solar panel system in Indiana will earn a federal solar tax credit of $6,498. However, it's important to keep in mind that this financial incentive is not an upfront payment. The tax credit reduces your federal income tax liability, so you'll see the savings when you file your taxes.

If what you owe in taxes is less than your federal tax credit, you'll owe $0 for the year. Any remaining tax credit value can be rolled over to next year. There's no income limit for the federal solar investment tax credit (ITC), so you can claim it as long as you have taxable income!

Indiana solar property tax exemption

Installing a solar energy system can potentially raise the value of your home. But raised property value can come with higher property taxes. Thankfully, Indiana offers a renewable energy property tax exemption where homes with solar power are 100% exempt from paying additional property taxes after an installation.

Experts at SolarReviews found that homes with solar sell for 6.9% more on average. Considering the median home value and the state’s average 0.75% property tax rate, those with home solar can save an estimated $124 per year in property taxes.

Indiana installation costs

A solar power system in Indiana costs $2.49 per watt, which would make the total cost of the average 8.7 kW system $21,663 before any incentives are applied. Once you factor in the federal tax credit, that amount falls to $15,164.

Federal tax credit: $21,663 x 30% = $6,498

Total savings: $6,498

Effective system cost: $21,663 - $6,498 = $15,164

These savings don’t include the additional utility bill savings from the solar buyback programs offered by your utility service provider. Those savings will vary depending on the kind of compensation rate offered to customers.

The total cost of solar panels will depend on a few factors, like how many solar panels you install, the solar company used, and the characteristics of your roof.

Do incentives and rebates make solar panels worthwhile in Indiana?

We would like to see Indiana offer more rebate programs to help lower the initial cost of photovoltaic systems. While a solar property tax exemption helps, a real game-changer will be if your utility offers a decent solar buyback program to help reduce those home energy bills. 

However, more solar programs targeting low-income households might be on the horizon. The Indiana Community Action Association Inc. (IN-CAA) is a nonprofit that serves the Indianapolis, Columbus, Fort Wayne, and Gary regions. IN-CAA is one of the many programs that received funding from the Environmental Protection Agency’s (EPA) Solar For All Initiative. So, keep an eye out for programs opening up in the near future.

In the meantime, we recommend getting at least three quotes from reputable solar installers to maximize your savings and get the best deal. Or, check out SolarReviews’s extensive directory of solar companies in Indiana to find one that could be a good fit for you.
