Common questions

How much do solar panels produce in winter in Freiburg im Breisgau?

From November to February the system produces about 1,446 kWh, which is 16% of the year. The weakest month (December) gives roughly 287 kWh.

Is an east-west roof worth it in Freiburg im Breisgau?

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.
