How much will solar panels produce in Recife?

A 5 kWp system facing north at 35° tilt in Recife produces about 8,163 kWh a year. In a weak year that is 6,848 kWh, in a good one 9,477 kWh — 1,633 kWh per kWp.

That’s about 408% of a typical home’s yearly use (2,000 kWh).

Common questions

How much do solar panels produce in winter in Recife?

From May to August the system produces about 2,937 kWh, which is 36% of the year. The weakest month (December) gives roughly 580 kWh.

Is an east-west roof worth it in Recife?

An east-west system typically produces 10–25% less per kWp than one facing north, but spreads production more evenly through the day. The exact difference depends on tilt and shading.

Ground mount or roof in Recife?

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.
