Net Metering Policies
Kentucky: retail rate net metering active. Ohio: retail rate net metering active.
Net metering is often the most economically significant solar policy because it determines how excess production is valued. Retail-rate states (where you receive full retail price for exported energy) have substantially better solar economics than avoided-cost or no-net-metering states.
Average 25-Year Savings
Kentucky: $25,400 over 25 years (avg payback 10.4 yrs). Ohio: $32,800 over 25 years (avg payback 8.7 yrs).
Verdict: Which State Wins on Solar?
Ohio delivers stronger lifetime solar economics than Kentucky due to more favorable net metering rules.
