Mississippi Power and Coast Electric serve Harrison County, so which rules apply depends on your address.

Solar Panel Installation in Biloxi FAQs
Is solar worth it in Biloxi?
The sun is strong (about 1,400 kWh a year per kW, our estimate), but export credits are low, so solar pays most when sized to what you use at home or paired with a battery. See the Mississippi incentives for the state credit.
Is there a federal solar tax credit in 2026?
No. The federal 25D credit ended for expenditures after December 31, 2025. Mississippi has no state solar tax credit that we could find, and its property tax exemption for renewable energy applies only to projects of $100 million or more.
Do I need a permit for solar panels in Biloxi?
Usually yes, and the utility may need to approve solar and batteries. Building Department handles permits in Biloxi; see the permit information above.
