Entergy Mississippi solar

Mississippi has the cheapest solar installs in the South and one of the longest paybacks in the country, and both facts come from the same place: the state’s power is cheap and its export credit is thin. Panels run $2.29-$2.59 a watt, a typical 9.12 kW system costs about $23,621 before incentives, and the Magnolia State gets strong sun — about 1,426 kilowatt-hours a year from every installed kilowatt. What the panels earn is governed by a Public Service Commission rule that pays exports at avoided cost plus a fixed 2.5-cent adder: 6.1 cents a kilowatt-hour at Entergy Mississippi, 5.89-6.40 cents at Mississippi Power, 4.5 cents at the co-ops, and just 3.112 cents in TVA territory in the north. There is no state tax credit, no sales-tax break, and no confirmed utility rebate, and the 30% federal credit is $0 for a homeowner-owned system installed in 2026. Payback lands near 21 years on Entergy and around 18 years statewide on the larger marketplace average, with low-income households doing better through a 2-cent export adder. Every size gets priced here, five cities get compared, the four different export prices get explained utility by utility, and the guide finishes by naming the households that still come out ahead in Mississippi — and the ones that should wait.
