How much will solar panels produce in Innsbruck?

A 6 kWp system facing south at 35° tilt in Innsbruck produces about 6,800 kWh a year. In a weak year that is 5,640 kWh, in a good one 7,960 kWh — 1,133 kWh per kWp.

That’s about 170% of a typical home’s yearly use (4,000 kWh).

Common questions

How much do solar panels produce in winter in Innsbruck?

From November to February the system produces about 919 kWh, which is 13% of the year. The weakest month (December) gives roughly 55 kWh.

Is an east-west roof worth it in Innsbruck?

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 Innsbruck?

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.
