Kentucky solar estimate

Solar Panel Cost in Kentucky (2026)

Installed solar in Kentucky runs about $2.55 per watt — roughly 1% below the national average of $2.58/W. With the federal residential tax credit (25D) gone as of 2026, payback here rests on a $0.13/kWh power price and 4.4 daily peak sun hours.

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

A $150/month electric bill in Kentucky works out to about 13,846 kWh a year. Sizing a cash-purchase system to cover 100% of that:

Local context: Kentucky moved to net billing below retail, trimming the value of exported solar.

Kentucky credits exported power at about 75% of the retail rate (NEM 3.0-style), so a battery to store and self-use your generation usually improves the return here.
