Solar in Hopkinsville: What Homeowners Should Know
Hopkinsville sees an average of 4.6 peak sun hours per day, which is what ultimately determines how much electricity a rooftop system produces here. A standard 8 kW system (about 20 panels) generates roughly 10,746 kWh each year in Hopkinsville — and paired with Kentucky's local electricity rate of $0.102/kWh, that's where the savings come from.
At those numbers, a Hopkinsville homeowner saves about $91/month ($1,096/year). Against a $22,400 system cost, that works out to a payback of about 20.4 years, after which the system produces essentially free power for two decades — an estimated $15,039 in lifetime savings. Note: the 30% federal tax credit expired at the end of 2025 for purchased systems, though a solar lease or PPA can still pass it through. The local grid is served by Pennyrile Electric, whose net metering policy directly affects how much credit you earn for surplus power.
