How much will solar panels produce in Dresden?

A 8 kWp system facing south at 35° tilt in Dresden produces about 8,665 kWh a year. In a weak year that is 7,187 kWh, in a good one 10,144 kWh — 1,083 kWh per kWp.

That’s about 248% of a typical home’s yearly use (3,500 kWh).

Common questions

How much do solar panels produce in winter in Dresden?

From November to February the system produces about 1,304 kWh, which is 15% of the year. The weakest month (December) gives roughly 228 kWh.

Is an east-west roof worth it in Dresden?

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 Dresden?

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.
