How much will solar panels produce in Praha?

A 6 kWp system facing south at 35° tilt in Praha produces about 6,711 kWh a year. In a weak year that is 5,590 kWh, in a good one 7,832 kWh — 1,119 kWh per kWp.

That’s about 224% of a typical home’s yearly use (3,000 kWh).

Common questions

How much do solar panels produce in winter in Praha?

From November to February the system produces about 997 kWh, which is 15% of the year. The weakest month (December) gives roughly 185 kWh.

Is an east-west roof worth it in Praha?

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 Praha?

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.
