Solar in Mississippi: the three numbers that decide it
Sun hours. Mississippi averages 5.3 peak sun hours a day (NREL), rank 13 of 51. After typical system losses that is about 1,533 kWh per installed kilowatt per year.
Electricity price. Residential power costs about 16.3¢/kWh (EIA, 2026), rank 27 of 51 — the higher the rate, the more each solar kilowatt-hour is worth.
Installed cost. Around $2.70 per watt before incentives (EnergySage marketplace data, 2026). With no federal credit for 2026 installs, this is the price you actually pay for an owned system.
Put together, a household with a $150 monthly bill would size a ~7.2 kW array, pay about $19,449, save roughly $1,800 in the first year and reach payback in about 10.8 yrs. Use the calculator above with your own bill.
