Net Metering Policy — Mississippi
How Mississippi compensates your excess solar production
Reduced export credits or net billing — you earn less than retail for excess solar. Moderate impact on payback.
Mississippi mandates net metering but credits are at the utility's avoided cost, below full retail rate.
