How much will solar panels produce in Nice?

A 6 kWp system facing south at 35° tilt in Nice produces about 9,401 kWh a year. In a weak year that is 7,867 kWh, in a good one 10,936 kWh — 1,567 kWh per kWp.

That’s about 200% of a typical home’s yearly use (4,700 kWh).

Common questions

How much do solar panels produce in winter in Nice?

From November to February the system produces about 2,123 kWh, which is 23% of the year. The weakest month (December) gives roughly 486 kWh.

Is an east-west roof worth it in Nice?

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 Nice?

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.
