Solar Panel Cost in Indianapolis, IN (2026 Estimate)

BySunMetricLab Editorial Team·Independent solar research and calculators

Data last updated September 10, 2026

Indianapolis averages about 4.4 peak sun hours a day (below the national average, a little sunnier than the Indiana average of 4.2), and pairs with Indiana's approximate residential rate near 15¢/kWh. In the model used here, an 8 kW system produces roughly 10,280 kWh a year and trims about $1,500 off annual electricity costs, paying back its net cost in about 10.9 years (versus 11.4 years for Indiana as a whole). Local shading, roof, and your utility's export terms move the real figure.

Estimated system cost and payback in Indianapolis

Costs assume roughly $3.00/watt installed; the net column applies a 30% federal credit for comparison with quotes that include it. Savings use Indianapolis's sun hours and Indiana's rate.

The 30% federal Residential Clean Energy Credit ended for systems paid for after December 31, 2025 under the 2025 federal budget law. Net-after-credit figures apply only if you still qualify (for example a 2025 expenditure, or a leased system where the installer passes a credit through). Confirm with a tax professional.

Net metering and utilities around Indianapolis

Indiana ended traditional net metering for customers of its investor-owned utilities through Senate Enrolled Act 309 of 2017, with the program closing to new enrollees no later than July 1, 2022. Homes that signed up before the cutoff keep retail net metering for a grandfathering period, until 2047 for systems interconnected before 2018 and until 2032 for those interconnected after. New rooftop systems at Duke Energy Indiana, AES Indiana, NIPSCO, CenterPoint and Indiana Michigan Power instead fall under an excess distributed generation (EDG) tariff.

Duke Energy Indiana is the largest provider and covers much of central and southern Indiana, AES Indiana serves Indianapolis, NIPSCO covers the northern third of the state, CenterPoint Energy serves the Evansville area and Indiana Michigan Power serves the Fort Wayne and South Bend regions. Roughly a third of Hoosiers get power from cooperatives or municipal utilities with their own solar rules. Residential rates have risen sharply over the past decade and sit above the regional average at several IOUs, which improves the value of self-consumed solar. Most residential tariffs are flat-rate with a fixed monthly charge and no demand charge, though several utilities offer optional time-of-use plans; with low EDG export credits, the goal is to use as much of your production on site as possible.
