How much will solar panels produce in Alicante?

A 5 kWp system facing south at 35° tilt in Alicante produces about 8,482 kWh a year. In a weak year that is 7,109 kWh, in a good one 9,856 kWh — 1,696 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 Alicante?

From November to February the system produces about 2,212 kWh, which is 26% of the year. The weakest month (December) gives roughly 535 kWh.

Is an east-west roof worth it in Alicante?

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 Alicante?

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.
