Solar Companies in Kentucky

Kentucky receives moderate solar irradiance with about 4.1 peak sun hours daily, and the Bluegrass State's solar market is in early growth stages. As a historically coal-dependent state, Kentucky has been slower to adopt solar-friendly policies, but the economics are gradually improving.

In 2019, Kentucky passed legislation transitioning net metering from full retail rates to avoided-cost rates for new solar customers. Louisville Gas & Electric (LG&E) and Kentucky Utilities (KU), both subsidiaries of PPL Corporation, serve the majority of the state. The Tennessee Valley Authority (TVA) serves parts of western Kentucky with its own renewable programs.

Louisville, Lexington, and Bowling Green are the leading residential solar markets. With low electricity rates around $0.11/kWh and reduced net metering compensation, payback periods tend to be longer at 12-15 years, though the federal tax credit and declining panel costs are steadily improving the picture.
