In short: Greensboro has about 307,400 people and sits in Guilford County. Duke Energy Carolinas, LLC, Duke Energy Progress and EnergyUnited Elec Member Corp serves different parts of Guilford County, so your utility depends on your address; their 2024 home averages range from 11.54¢ to 15.54¢ per kWh (EIA). FEMA rates Guilford County ice storms “very high”. Rooftop solar here makes roughly 1,270 kWh a year per kW of panels by our estimate, which is good for solar.
This page covers what is local to Greensboro: its utility, outage records, sunshine, weather risks and charging. Statewide rules such as net metering, incentives and electrician licensing are in our North Carolina energy guide and the wider area is covered in the Greensboro-Winston-Salem guide.

Your utility and what it means
Duke Energy Carolinas, LLC is an investor-owned utility and served about 1,919,372 home customers in 2024; its 13.94¢ average was below the 15.16¢ statewide average for July 2026. Duke Energy Progress is an investor-owned utility and served about 1,356,079 home customers in 2024; its 15.54¢ average was close to the 15.16¢ statewide average for July 2026. EnergyUnited Elec Member Corp is a member-owned cooperative utility and served about 121,995 home customers in 2024; its 11.54¢ average was below the 15.16¢ statewide average for July 2026. Those are utility-wide averages, not a quote for your address; your own bill is the real number.
For reliability, Duke Energy Carolinas, LLC reported 168 minutes per customer without major storms in 2024, more than the statewide figure of 141 (EIA-861). Utility-wide numbers hide a lot: a home at the end of a long rural line usually has more outages than the average.
Net metering, export rates and incentives are set at state level and by each utility. Start with the North Carolina guide and then ask your utility for its current interconnection steps before you sign anything.
Backup power in Greensboro
- Ice storms (very high): Ice storms bring down lines for days. A standby generator with a transfer switch, or a battery sized for the fridge, furnace blower and well pump, matters more than a small power station.
- River and heavy-rain flooding (relatively high): Heavy rain can flood basements and take out power. Put sump pumps on backup power and keep equipment above the flood line.
- Short outages: a portable power station covers phones, Wi-Fi, a CPAP and lights; a home battery switches over automatically.
Size your setup with the generator sizing tool and the battery backup calculator, and compare options in backup power. Generator safety (CPSC): outdoors only, at least 20 feet from the house, exhaust away from doors and windows, never in a garage, and battery-powered carbon monoxide alarms inside. A licensed electrician should install any transfer switch, with a permit; see generator installation.
Solar in Greensboro
By our rough estimate each kW of panels makes about 1,270 kWh a year in Greensboro (NASA sunshine data times 365 days times 0.80 for system losses). Valued at Duke Energy Carolinas, LLC’s 2024 average of 13.94¢, that is about $177 a year per kW if all of it offsets your own use (an estimate, not a promise). Production swings with the seasons: June is the sunniest month at 6.34 and December the dimmest at 2.17, a 2.9-to-1 gap.
Check your own roof with the solar potential tool, see solar costs and net metering vs net billing, and read the steps in solar installation.
Batteries and EV charging
A home battery earns its place when outages are frequent, when your utility pays little for exported solar, or when evening prices are high; compare in home batteries and battery costs. Greensboro has 196 public charging ports in the federal station list including 72 DC fast, but home charging is cheaper and easier: see the EV charging cost calculator and EV charger installation.

Permits and inspections
Solar, generator transfer switches and EV chargers normally need an electrical permit from the Greensboro building or permitting department, or from Guilford County if you live outside city limits, and often a utility interconnection approval. We have not verified a local permit page for Greensboro, so check the city and county websites or ask your electrician, who will know the process. Hire only a licensed electrician or installer; the North Carolina guide lists the state licensing rules.

Greensboro energy FAQ
Who is my electric company in Greensboro?
Duke Energy Carolinas, LLC, Duke Energy Progress and EnergyUnited Elec Member Corp all serve parts of Guilford County. Which one serves you depends on your street, so check the top of your bill. Their 2024 home price averages differ (Duke Energy Carolinas, LLC 13.94¢, Duke Energy Progress 15.54¢, EnergyUnited Elec Member Corp 11.54¢) so it matters for solar math.
How much power will solar make in Greensboro?
About 1,270 kWh a year per kW of panels by our estimate, so a 6 kW system would make roughly 7,620 kWh. Shade, roof direction and tilt change this; run your address through the solar potential tool for a better number.
Is a generator or a battery better for ice storms in Guilford County?
It depends how long the outage lasts. A battery is quiet, automatic and good for short outages and for pairing with solar; a standby generator keeps going as long as it has fuel, which suits multi-day events. Many homes use a battery for everyday outages and add a generator for the rare long one.
Do I need a permit for solar or a generator in Greensboro?
Almost always an electrical permit for a transfer switch, solar or an EV charger, issued by the city or county where you live. Your licensed electrician or installer normally pulls it. Never connect a generator to your house wiring without a transfer switch.
