How much will solar panels produce in Kielce?
A 6 kWp system facing south at 35° tilt in Kielce produces about 6,470 kWh a year. In a weak year that is 5,367 kWh, in a good one 7,573 kWh — 1,078 kWh per kWp.

Common questions
How much do solar panels produce in winter in Kielce?
From November to February the system produces about 854 kWh, which is 13% of the year. The weakest month (December) gives roughly 148 kWh.
Is an east-west roof worth it in Kielce?
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 Kielce?
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.
