Common questions

How much do solar panels produce in winter in Fribourg?

From November to February the system produces about 1,798 kWh, which is 18% of the year. The weakest month (December) gives roughly 330 kWh.

Is an east-west roof worth it in Fribourg?

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 Fribourg?

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.
