Louisiana Solar Guide 2026
Everything Louisiana homeowners need to know: costs, incentives, net metering policy, and what makes this state unique for solar.
Key fact about Louisiana solar
Louisiana has excellent sun hours and full retail net metering, but the lowest electricity rates in the US (~$0.10/kWh) make payback very long. Hurricane resilience (battery backup) is often as important as bill savings here.
