Mississippi solar estimate

Solar Panel Cost in Mississippi (2026)

Installed solar in Mississippi runs about $2.55 per watt — roughly 1% below the national average of $2.58/W. With the federal residential tax credit (25D) gone as of 2026, payback here rests on a $0.15/kWh power price and 4.9 daily peak sun hours.

Worked example: a typical $150/month home in Mississippi

A $150/month electric bill in Mississippi works out to about 12,245 kWh a year. Sizing a cash-purchase system to cover 100% of that:

$/W: industry pricing surveys · electricity: U.S. EIA, 12-month average through April 2026 · sun hours: NREL.

Local context: Mississippi added a modest net-metering adder but still values exports below retail.

Mississippi credits exported power at about 90% of the retail rate (NEM 3.0-style), so a battery to store and self-use your generation usually improves the return here.
