Kentucky solar notes
Kentucky replaced 1:1 net metering in 2021 with utility-set export rates well below retail, reducing the value of exported solar.
Heads up: the 30% federal tax credit for purchased home solar ended Dec 31, 2025. Leased/PPA systems may still qualify through 2027, and Kentucky may offer its own incentives — check locally.
