Commercial Solar in Indiana in 2026
Indiana ranks among the Midwest's top manufacturing states, and for the state's manufacturing and distribution base, commercial solar has become an increasingly common operating cost reduction strategy. AES Indiana (Indianapolis metro) and Duke Energy Indiana (central and northern IN) commercial rates have increased as the state transitions from coal. Several Indiana counties — particularly in southwest Indiana near former coal plants — qualify for the 10% federal energy community ITC adder. Check the DOE energy communities mapping tool for your specific Indiana county. Our partners are active in Indianapolis, Fort Wayne, South Bend, and Evansville.
