How much will solar panels produce in Faro?

A 5 kWp system facing south at 35° tilt in Faro produces about 8,847 kWh a year. In a weak year that is 7,417 kWh, in a good one 10,276 kWh — 1,769 kWh per kWp.

That’s about 295% of a typical home’s yearly use (3,000 kWh).

Common questions

How much do solar panels produce in winter in Faro?

From November to February the system produces about 2,351 kWh, which is 26% of the year. The weakest month (December) gives roughly 549 kWh.

Is an east-west roof worth it in Faro?

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 Faro?

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.
