Solar potential of Tai’an explained

Tai’an receives an average of 3.91 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 1142 kWh of electricity per year here, assuming a well-oriented system with a typical 80% performance ratio. This is a solid mid-range solar resource: production is meaningful year-round, though winter output drops noticeably.

Frequently asked questions

Is solar worth it in Tai’an?

With 3.91 kWh/m²/day of average irradiation, a 1 kWp system in Tai’an produces roughly 1142 kWh per year. That is a good solar resource; with current panel prices most systems pay back well within their lifetime.

How much electricity would a 5 kW system produce in Tai’an?

Approximately 6,000 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%.
