How much will solar panels produce in Catania?

A 6 kWp system facing south at 35° tilt in Catania produces about 9,807 kWh a year. In a weak year that is 8,215 kWh, in a good one 11,400 kWh — 1,635 kWh per kWp.

Common questions

How much do solar panels produce in winter in Catania?

From November to February the system produces about 2,584 kWh, which is 26% of the year. The weakest month (November) gives roughly 611 kWh.

Is an east-west roof worth it in Catania?

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 Catania?

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.
