How much will solar panels produce in Antwerpen?

A 5 kWp system facing south at 35° tilt in Antwerpen produces about 5,303 kWh a year. In a weak year that is 4,398 kWh, in a good one 6,208 kWh — 1,061 kWh per kWp.

That’s about 152% of a typical home’s yearly use (3,500 kWh).

Common questions

How much do solar panels produce in winter in Antwerpen?

From November to February the system produces about 810 kWh, which is 15% of the year. The weakest month (December) gives roughly 133 kWh.

Is an east-west roof worth it in Antwerpen?

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 Antwerpen?

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.
