How much will solar panels produce in Kraków?

A 6 kWp system facing south at 35° tilt in Kraków produces about 6,688 kWh a year. In a weak year that is 5,575 kWh, in a good one 7,801 kWh — 1,115 kWh per kWp.

That’s about 268% of a typical home’s yearly use (2,500 kWh).

Common questions

How much do solar panels produce in winter in Kraków?

From November to February the system produces about 991 kWh, which is 15% of the year. The weakest month (December) gives roughly 185 kWh.

Is an east-west roof worth it in Kraków?

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 Kraków?

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.
