Solar in Horn Lake: What Homeowners Should Know
Horn Lake sees an average of 4.9 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 11,446 kWh each year in Horn Lake — and paired with Mississippi's local electricity rate of $0.095/kWh, that's where the savings come from.
At those numbers, a Horn Lake homeowner saves about $91/month ($1,087/year). Against a $22,000 system cost, that works out to a payback of about 20.2 years, after which the system produces essentially free power for two decades — an estimated $15,143 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 Entergy Mississippi, whose net metering policy directly affects how much credit you earn for surplus power.
