Indiana offers a property tax exemption for the assessed value of most renewable energy systems, typically based on the actual cost of components and labor. Effectively this means that you can increase the value of your home without paying tax on the increased value. Commercial and industrial property owners may also claim this exemption.
The few home sales to date that have involved rooftop solar in Indiana do show it to be an advantage, not only in commanding a higher price but also resulting in less time on the market. A national study found that home buyers are willing to pay more for houses with rooftop solar systems. Data on properties with other renewable technologies is scattered, but suggestive of the same advantage.
