How much will solar panels produce in Darwin?

A 6.6 kWp system facing north at 35° tilt in Darwin produces about 11,117 kWh a year. In a weak year that is 9,323 kWh, in a good one 12,912 kWh — 1,684 kWh per kWp.

That’s about 202% of a typical home’s yearly use (5,500 kWh).

Common questions

How much do solar panels produce in winter in Darwin?

From May to August the system produces about 4,537 kWh, which is 41% of the year. The weakest month (January) gives roughly 639 kWh.

Is an east-west roof worth it in Darwin?

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 Darwin?

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.
