How much will solar panels produce in Opole?
A 6 kWp system facing south at 35° tilt in Opole produces about 6,794 kWh a year. In a weak year that is 5,632 kWh, in a good one 7,955 kWh — 1,132 kWh per kWp.
That’s about 272% of a typical home’s yearly use (2,500 kWh).

Common questions
How much do solar panels produce in winter in Opole?
From November to February the system produces about 980 kWh, which is 15% of the year. The weakest month (December) gives roughly 163 kWh.
Is an east-west roof worth it in Opole?
An east-west system typically produces 10–25% less per kWp than one facing south, but spreads production more evenly through the day. The exact difference depends on tilt and shading.
Ground mount or roof in Opole?
A ground mount can be tilted and aimed freely, which can add some yield, but it costs more and needs space. Compare both for your own plot.
