How much will solar panels produce in Amsterdam?

A 4 kWp system facing south at 35° tilt in Amsterdam produces about 4,193 kWh a year. In a weak year that is 3,481 kWh, in a good one 4,906 kWh — 1,048 kWh per kWp.

That’s about 150% of a typical home’s yearly use (2,800 kWh).

Common questions

How much do solar panels produce in winter in Amsterdam?

From November to February the system produces about 606 kWh, which is 14% of the year. The weakest month (December) gives roughly 99 kWh.

Is an east-west roof worth it in Amsterdam?

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 Amsterdam?

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.
