How much will solar panels produce in Davos?

A 8 kWp system facing south at 35° tilt in Davos produces about 8,429 kWh a year. In a weak year that is 7,012 kWh, in a good one 9,846 kWh — 1,054 kWh per kWp.

That’s about 187% of a typical home’s yearly use (4,500 kWh).

Common questions

How much do solar panels produce in winter in Davos?

From November to February the system produces about 887 kWh, which is 11% of the year. The weakest month (December) gives roughly 98 kWh.

Is an east-west roof worth it in Davos?

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 Davos?

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.
