Solar potential of Bydgoszcz explained
Bydgoszcz receives an average of 2.94 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 858 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 Bydgoszcz?
With 2.94 kWh/m²/day of average irradiation, a 1 kWp system in Bydgoszcz produces roughly 858 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 Bydgoszcz?
Approximately 4,000 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%.
