How much will solar panels produce in Valencia?

A 5 kWp system facing south at 35° tilt in Valencia produces about 8,465 kWh a year. In a weak year that is 7,082 kWh, in a good one 9,849 kWh — 1,693 kWh per kWp.

That’s about 257% of a typical home’s yearly use (3,300 kWh).

Common questions

How much do solar panels produce in winter in Valencia?

From November to February the system produces about 2,264 kWh, which is 27% of the year. The weakest month (November) gives roughly 536 kWh.

Is an east-west roof worth it in Valencia?

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 Valencia?

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.
