Solar Panel Cost in Mississippi (2026)

A typical Mississippi rooftop system costs around $2.75/W cash, installed, before incentives — with most quotes landing between $2.5/W and $3/W. The federal residential tax credit is $0 for 2026 installations (it ended 12/31/2025).

The federal residential solar tax credit (30% §25D) ended December 31, 2025.

Under the One Big Beautiful Bill Act, systems placed in service on or after January 1, 2026 do not qualify for the residential credit. Systems installed and operational by December 31, 2025 can still be claimed at 30% on the 2025 return. Commercial and third-party-owned (lease/PPA) projects may qualify under §48E — see the federal incentives page.

Solar resource & economics

Production factor (est.): 1589 kWh/kW/yr
10 kW annual production (est.): 13,665 kWh
Year-1 savings for 10 kW at avg rate, 35% self-use: $1,849
Simple payback (net cost ÷ Yr-1 savings, rough): ≈ 25 yrs

These are rough planning numbers. Model your exact scenario in the price calculator — assumptions are visible and adjustable.

Export policy detail

No statewide net-metering statute; utility terms vary and are often limited.

Why it matters: if exports are credited at the retail rate (1:1 net metering), every kWh counts the same. Under net billing or avoided-cost export, storing daytime power (battery) or shifting use matters far more. Your utility’s tariff — not the state average — decides this. Utility records

Incentives in Mississippi (status-aware)

No curated incentive records yet for Mississippi. This does not mean none exist — check the DSIRE database and your state energy office before budgeting. We add verified records over time.

Tax exemptions: Property tax exemption not confirmed for this state.

Federal residential credit (§25D): expired 12/31/2025 — $0 for 2026 installations. Commercial/third-party-owned projects: see federal incentives.

Local considerations

High cooling load; limited export value at many utilities.
No major state incentive program.

Battery note: batteries add roughly $1,000–$2,000/kWh installed and rarely pay for themselves on energy savings alone. In Mississippi, storage value depends on your export policy (limited), TOU rates and outage risk — model it in the battery calculator.
