Utility rules and programs for Greenville
Duke Energy Carolinas and Blue Ridge Electric Coop serve Greenville County, so which rules apply depends on your address.
| Utility | Type | Solar export rule |
|---|---|---|
| Duke Energy Carolinas, LLC | investor-owned | Duke’s residential solar time-of-use plan nets exports within the same billing month and price period, pays leftovers at about 3.8 to 4 cents per kWh, and has a $30 minimum bill and an extra fee on systems over 15 kW (installer guide; Duke’s tariff was not read). |
| Blue Ridge Electric Coop Inc | member-owned cooperative | We could not read Blue Ridge Electric Cooperative’s solar terms. A 2014 state law requires every distribution co-op to adopt its own net metering policy, so ask for the written export rate and any cap. |
Program details are from each utility’s own pages (read October 2026). See the South Carolina 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 1,340 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 South Carolina 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. South Carolina allows an income tax credit of 25 percent of a solar system’s cost, up to $3,500 a year, with unused credit carried forward up to 10 years (SC Code 12-6-3587).
Do I need a permit for solar panels in Greenville?
Usually yes, and the utility may need to approve solar and batteries. Planning and Development, Building Permits, City of Greenville handles permits in Greenville; see the permit information above.
