How much will solar panels produce in Madrid?

A 5 kWp system facing south at 35° tilt in Madrid produces about 8,180 kWh a year. In a weak year that is 6,838 kWh, in a good one 9,522 kWh — 1,636 kWh per kWp.

That’s about 248% of a typical home’s yearly use (3,300 kWh).

Common questions

How much do solar panels produce in winter in Madrid?

From November to February the system produces about 2,020 kWh, which is 24% of the year. The weakest month (November) gives roughly 466 kWh.

Is an east-west roof worth it in Madrid?

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 Madrid?

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.
