How much will solar panels produce in Strasbourg?

A 6 kWp system facing south at 35° tilt in Strasbourg produces about 7,018 kWh a year. In a weak year that is 5,847 kWh, in a good one 8,188 kWh — 1,170 kWh per kWp.

That’s about 149% of a typical home’s yearly use (4,700 kWh).

Common questions

How much do solar panels produce in winter in Strasbourg?

From November to February the system produces about 1,054 kWh, which is 15% of the year. The weakest month (December) gives roughly 184 kWh.

Is an east-west roof worth it in Strasbourg?

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 Strasbourg?

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.
