How much will solar panels produce in Paris?
A 6 kWp system facing south at 35° tilt in Paris produces about 7,100 kWh a year. In a weak year that is 5,897 kWh, in a good one 8,303 kWh — 1,183 kWh per kWp.
That’s about 151% of a typical home’s yearly use (4,700 kWh).

Common questions
How much do solar panels produce in winter in Paris?
From November to February the system produces about 1,166 kWh, which is 16% of the year. The weakest month (December) gives roughly 216 kWh.
Is an east-west roof worth it in Paris?
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 Paris?
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.
