How much will solar panels produce in Kiel?

A 8 kWp system facing south at 35° tilt in Kiel produces about 8,037 kWh a year. In a weak year that is 6,677 kWh, in a good one 9,398 kWh — 1,005 kWh per kWp.

That’s about 230% of a typical home’s yearly use (3,500 kWh).

Common questions

How much do solar panels produce in winter in Kiel?

From November to February the system produces about 909 kWh, which is 11% of the year. The weakest month (December) gives roughly 130 kWh.

Is an east-west roof worth it in Kiel?

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 Kiel?

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.
