How much will solar panels produce in Pamplona?

A 5 kWp system facing south at 35° tilt in Pamplona produces about 7,002 kWh a year. In a weak year that is 5,852 kWh, in a good one 8,152 kWh — 1,400 kWh per kWp.

That’s about 212% of a typical home’s yearly use (3,300 kWh).

Common questions

How much do solar panels produce in winter in Pamplona?

From November to February the system produces about 1,456 kWh, which is 21% of the year. The weakest month (December) gives roughly 323 kWh.

Is an east-west roof worth it in Pamplona?

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 Pamplona?

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.
