Missouri Solar Guide 2026
Everything Missouri homeowners need to know: costs, incentives, net metering policy, and what makes this state unique for solar.
Key fact about Missouri solar
Missouri has decent sun hours (4.8/day) and full retail net metering, but very low electricity rates (~$0.11/kWh) push payback to ~13 years. Solar is a long-term investment here rather than a quick-payback proposition.
