In short: Sitka has about 8,400 people and sits in Sitka County. Which company supplies power depends on the street address, so check your bill first. FEMA rates Sitka County landslides “relatively high”. Rooftop solar here makes roughly 670 kWh a year per kW of panels by our estimate, which is on the modest side, so price and incentives matter more.
This page covers what is local to Sitka: its utility, outage records, sunshine, weather risks and charging. Statewide rules such as net metering, incentives and electrician licensing are in our Alaska energy guide.
Sitka at a glance
- Place: Sitka, Sitka County, Alaska; about 8,355 residents (Census Bureau estimate, July 2024).
- Sun: 2.30 kWh per square meter per day on average, from 0.25 in December to 4.50 in June (NASA POWER). Our rough estimate: about 670 kWh a year per kW of panels.
- Climate: about 0 cooling degree-days and 7,410 heating degree-days a year (base 65°F, NASA POWER), so heating is the big load.
- Top hazards in Sitka County: landslides “relatively high”, volcanic activity “relatively moderate” and avalanches “relatively moderate” (FEMA National Risk Index; overall county risk rated “very low”).
Your utility and what it means
We could not match a utility in the federal data for Sitka County. Look at the top of your electric bill for the company name, then check its page for solar, battery and EV-charger programs.
Net metering, export rates and incentives are set at state level and by each utility. Start with the Alaska guide and then ask your utility for its current interconnection steps before you sign anything.
Backup power in Sitka
- 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 Sitka
By our rough estimate each kW of panels makes about 670 kWh a year in Sitka (NASA sunshine data times 365 days times 0.80 for system losses). Production swings with the seasons: June is the sunniest month at 4.50 and December the dimmest at 0.25, a 17.9-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. The federal station list shows few or no public chargers listed under Sitka, so a home charger matters more here: see the EV charging cost calculator and EV charger installation.
Drive on another fuel? See every alternative fuel station in Sitka: hydrogen, propane, natural gas, E85 ethanol, biodiesel and renewable diesel.
Permits and inspections
Solar, generator transfer switches and EV chargers normally need an electrical permit from the Sitka building or permitting department, or from Sitka County if you live outside city limits, and often a utility interconnection approval. We have not verified a local permit page for Sitka, so check the city and county websites or ask your electrician, who will know the process. Hire only a licensed electrician or installer; the Alaska guide lists the state licensing rules.

Sitka energy FAQ
How much power will solar make in Sitka?
About 670 kWh a year per kW of panels by our estimate, so a 6 kW system would make roughly 4,020 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 Sitka?
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.
