In short: Clayton has about 4,511 people and sits in Kent County. Delmarva Power, Delaware Electric Cooperative and City of Dover serves different parts of Kent County, so your utility depends on your address; their 2024 home averages range from 14.22¢ to 17.23¢ per kWh (EIA). FEMA rates Kent County cold waves “relatively high”. Rooftop solar here makes roughly 1,190 kWh a year per kW of panels by our estimate, which is about average for the U.S..
This page covers what is local to Clayton: its utility, outage records, sunshine, weather risks and charging. Statewide rules such as net metering, incentives and electrician licensing are in our Delaware energy guide and the wider area is covered in the Dover, DE guide.

Your utility and what it means
Delmarva Power is an investor-owned utility and served about 275,018 home customers in 2024; its 17.23¢ average was below the 18.48¢ statewide average for July 2026. Delaware Electric Cooperative is a member-owned cooperative utility and served about 104,839 home customers in 2024; its 14.22¢ average was below the 18.48¢ statewide average for July 2026. City of Dover is a city-owned utility and served about 21,601 home customers in 2024; its 15.52¢ average was below the 18.48¢ 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, Delmarva Power reported 68 minutes per customer without major storms in 2024, more than the statewide figure of 66 (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 Delaware guide and then ask your utility for its current interconnection steps before you sign anything.
Backup power in Clayton
- Cold waves (relatively high): Cold waves raise demand and can cause both outages and frozen pipes. Keep at least one room warm with a battery-run heater circuit or a generator.
- Winter weather (relatively high): Winter storms and cold snaps combine outages with heating demand. Plan for the furnace blower or heat pump, not just lights, and keep a fuel supply you can reach in snow.
- 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 Clayton
By our rough estimate each kW of panels makes about 1,190 kWh a year in Clayton (NASA sunshine data times 365 days times 0.80 for system losses). Valued at Delmarva Power’s 2024 average of 17.23¢, that is about $205 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 6.17 and December the dimmest at 1.75, a 3.5-to-1 gap, so a battery or a bigger system helps in winter.
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. Clayton has 6 public charging ports in the federal station list (none of them 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 Clayton building or permitting department, or from Kent County if you live outside city limits, and often a utility interconnection approval. We have not verified a local permit page for Clayton, so check the city and county websites or ask your electrician, who will know the process. Hire only a licensed electrician or installer; the Delaware guide lists the state licensing rules.

Clayton energy FAQ
Who is my electric company in Clayton?
Delmarva Power, Delaware Electric Cooperative and City of Dover all serve parts of Kent County. Which one serves you depends on your street, so check the top of your bill. Their 2024 home price averages differ (Delmarva Power 17.23¢, Delaware Electric Cooperative 14.22¢, City of Dover 15.52¢) so it matters for solar math.
How much power will solar make in Clayton?
About 1,190 kWh a year per kW of panels by our estimate, so a 6 kW system would make roughly 7,140 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 cold waves in Kent 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 Clayton?
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.
