Indiana solar estimate

Solar Panel Cost in Indiana (2026)

Installed solar in Indiana runs about $2.65 per watt — roughly 3% above the national average of $2.58/W. With the federal residential tax credit (25D) gone as of 2026, payback here rests on a $0.17/kWh power price and 4.3 daily peak sun hours.

Worked example: a typical $150/month home in Indiana

A $150/month electric bill in Indiana works out to about 10,714 kWh a year. Sizing a cash-purchase system to cover 100% of that:

Local context: Indiana phased out full net metering; new systems get instantaneous netting at a lower export value.

Indiana credits exported power at about 80% of the retail rate (NEM 3.0-style), so a battery to store and self-use your generation usually improves the return here.
