Solar potential of Aomori explained

Aomori receives an average of 3.28 kilowatt-hours of solar energy per square metre per day, measured over four decades of satellite observation. In practical terms, every kilowatt-peak of installed PV capacity yields about 958 kWh of electricity per year here, assuming a well-oriented system with a typical 80% performance ratio. While winters are dark, modern panel prices mean solar can still be economical — self-consumption value matters more than raw sunshine here.

Frequently asked questions

Is solar worth it in Aomori?

With 3.28 kWh/m²/day of average irradiation, a 1 kWp system in Aomori produces roughly 958 kWh per year. That is a moderate solar resource; economics depend more on local electricity prices and incentives, which our AI planner can research for you.

How much electricity would a 5 kW system produce in Aomori?

Approximately 5,000 kWh per year — enough to cover a large share of a typical household's consumption.

What data is this based on?

Long-term satellite observations from NASA POWER (1981–present) and the PVGIS SARAH3 database, assuming a performance ratio of 80%.
