How much will solar panels produce in Maastricht?

A 4 kWp system facing south at 35° tilt in Maastricht produces about 4,343 kWh a year. In a weak year that is 3,594 kWh, in a good one 5,091 kWh — 1,086 kWh per kWp.

That’s about 155% of a typical home’s yearly use (2,800 kWh).

Common questions

How much do solar panels produce in winter in Maastricht?

From November to February the system produces about 657 kWh, which is 15% of the year. The weakest month (December) gives roughly 109 kWh.

Is an east-west roof worth it in Maastricht?

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 Maastricht?

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.
