Are Solar Panels Worth It in Mississippi?

Last updated July 1, 2026 · based on Mississippi energy prices

Short answer: A typical 7 kW solar system in Mississippi produces about 9,800 kWh/year, saves roughly $1,078/year, and pays for itself in about 19.5 years in 2026 — with no federal tax credit, which expired December 31, 2025.

In Mississippi, where residential electricity averages about 13¢/kWh and rooftop solar yields roughly 1,400 kWh per kW per year, solar has a longer payback here (about 19.5 years) because electricity is relatively cheap — it makes the most sense if your rate is rising or you value energy independence.

Figures use Mississippi average prices, a 7 kW system at $3.00/watt, 50% self-consumption at retail plus a conservative 9¢/kWh net-metering credit, and ~0.5%/yr panel degradation. Sources: EIA electricity prices and NREL PVWatts production modeling.

What this means for Mississippi homeowners in 2026

The 30% federal residential solar tax credit (Section 25D) expired December 31, 2025, so a 2026 installation in Mississippi carries the full upfront cost unless a state or utility incentive applies. Because Mississippi electricity costs relatively little, the payback case is more marginal — strongest for high electricity users, south-facing roofs, and homeowners who plan to stay long term.
