Utility rules and programs for Greenville
Entergy Mississippi and Delta Electric serve Washington County, so which rules apply depends on your address.
| Utility | Type | Solar export rule |
|---|---|---|
| Entergy Mississippi LLC | investor-owned | Entergy Mississippi credits exported solar power at 6.1 cents per kWh from the first billing cycle of February 2026 (3.6 cents avoided cost plus 2.5 cents; 8.1 cents for low-to-moderate income households). Credits carry forward but cannot reduce fixed customer charges. Residential systems are limited to 20 kW DC and 110 percent of prior-year use; apply for a Level 1 interconnection agreement first; a $95 or $135 one-time fee applies. |
| Delta Electric Power Assn | member-owned cooperative | This member-owned co-op sets its own solar terms. We could not confirm its export rate; ask what exported power earns and how to apply. |
Program details are from each utility’s own pages (read October 2026). See the Mississippi incentives table for statewide credits and a status for every program.

Solar Panel Installation in Greenville FAQs
Is solar worth it in Greenville?
The sun is strong (about 1,330 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 Greenville?
Usually yes, and the utility may need to approve solar and batteries. City of Greenville, Mississippi handles permits in Greenville; see the permit information above.
