How much will solar panels produce in Natal?

A 5 kWp system facing north at 35° tilt in Natal produces about 8,294 kWh a year. In a weak year that is 6,958 kWh, in a good one 9,630 kWh — 1,659 kWh per kWp.

That’s about 415% of a typical home’s yearly use (2,000 kWh).

Common questions

How much do solar panels produce in winter in Natal?

From May to August the system produces about 3,093 kWh, which is 37% of the year. The weakest month (December) gives roughly 556 kWh.

Is an east-west roof worth it in Natal?

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 Natal?

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.
