Rooftop solar here makes roughly 1,070 kWh a year per kW of panels by our estimate, which is on the modest side, so price and incentives matter more.

Your utility and what it means
Public Service Co of NH is an investor-owned utility and served about 279,131 home customers in 2024; its 22.65¢ average was below the 26.6¢ statewide average for July 2026. New Hampshire Elec Coop Inc is a member-owned cooperative utility and served about 72,772 home customers in 2024; its 23.83¢ average was below the 26.6¢ statewide average for July 2026. Liberty Utilities (Granite State Electri is an investor-owned utility and served about 24,689 home customers in 2024; its 22.87¢ average was below the 26.6¢ 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, New Hampshire Elec Coop Inc reported 515 minutes per customer without major storms in 2024, more than the statewide figure of 132 (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 New Hampshire guide and then ask your utility for its current interconnection steps before you sign anything.
Backup power in Claremont
- Ice storms (relatively moderate): 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.
- Heating load: a winter outage can stop a furnace blower, boiler pump or heat pump. List what your heat needs to run before choosing a generator or battery.
- 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 Claremont
By our rough estimate each kW of panels makes about 1,070 kWh a year in Claremont (NASA sunshine data times 365 days times 0.80 for system losses). Valued at Public Service Co of NH’s 2024 average of 22.65¢, that is about $242 a year per kW if all of it offsets your own use (an estimate, not a promise). Production swings with the seasons: July is the sunniest month at 5.82 and December the dimmest at 1.24, a 4.7-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. Claremont has 8 public charging ports in the federal station list including 3 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 Claremont building or permitting department, or from Sullivan County if you live outside city limits, and often a utility interconnection approval. We have not verified a local permit page for Claremont, so check the city and county websites or ask your electrician, who will know the process. Hire only a licensed electrician or installer; the New Hampshire guide lists the state licensing rules.

Claremont energy FAQ
Who is my electric company in Claremont?
Public Service Co of NH, New Hampshire Elec Coop Inc and Liberty Utilities (Granite State Electri all serve parts of Sullivan County. Which one serves you depends on your street, so check the top of your bill. Their 2024 home price averages differ (Public Service Co of NH 22.65¢, New Hampshire Elec Coop Inc 23.83¢, Liberty Utilities (Granite State Electri 22.87¢) so it matters for solar math.
How much power will solar make in Claremont?
About 1,070 kWh a year per kW of panels by our estimate, so a 6 kW system would make roughly 6,420 kWh. Shade, roof direction and tilt change this; run your address through the solar potential tool for a better number.
Will a home battery keep my heat on in an outage?
It can keep a furnace blower, boiler pump or a heat pump running for a while, but long cold outages drain a battery fast without solar to recharge it. Pair it with a generator or wood or propane heat if outages here run for days.
Do I need a permit for solar or a generator in Claremont?
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.
