Solar cost in Mississippi by system size
Same assumptions as the typical home above; only the system size changes. Prices are the state median before incentives and include the incentives our calculator applies by default in Mississippi.

|---|---|---|---|---|---|
| 4 kW | $14,400 | $14,400 | 5,660 | $600 | 21 |
| 6 kW | $21,600 | $21,600 | 8,480 | $900 | 21 |

Incentives that lower the price in Mississippi
Business credit for leased and PPA systems (48E)
Claimed by the system owner, not the homeowner; solar must begin construction by July 4, 2026 or be in service by December 31, 2027[6]
If a company owns the panels on your roof (a lease or power purchase agreement), that company may claim the business clean electricity investment credit and can reflect it in your price. You cannot claim it yourself.
- Who
- Third-party-owned systems (leases and PPAs). Ask the provider whether the price assumes this credit.
- Deadline
- December 31, 2027
- Checked

How Mississippi utilities credit your solar
Customers of investor-owned utilities buy all grid power at retail and get a bill credit for each exported kWh at the utility's avoided cost plus a 2.5 cents/kWh distributed generation adder (Entergy Mississippi: 6.1 cents/kWh in 2026; 8.1 cents for low-to-moderate income households). Leftover credits carry forward monthly.[5]
We have not added every Mississippi utility yet, so the estimates on this page use the state-level rule: Entergy Mississippi credits exports from new solar customers at about 6.10¢ per kWh; we use it for Mississippi. Other utilities differ.[5]

How much do solar panels cost in Mississippi?
How long does solar take to pay for itself in Mississippi?
Is there still a federal solar tax credit?
Not for homeowners who buy. The Federal Residential Clean Energy Credit (25D)[7] does not apply to systems whose installation is completed after December 31, 2025. Leased and PPA systems are different: the company that owns the system may still claim a business credit.
