How much will solar panels produce in Montpellier?

A 6 kWp system facing south at 35° tilt in Montpellier produces about 9,195 kWh a year. In a weak year that is 7,693 kWh, in a good one 10,698 kWh — 1,533 kWh per kWp.

That’s about 196% of a typical home’s yearly use (4,700 kWh).

Common questions

How much do solar panels produce in winter in Montpellier?

From November to February the system produces about 2,138 kWh, which is 23% of the year. The weakest month (December) gives roughly 451 kWh.

Is an east-west roof worth it in Montpellier?

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 Montpellier?

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.
