How much will solar panels produce in Adelaide?

A 6.6 kWp system facing north at 35° tilt in Adelaide produces about 10,835 kWh a year. In a weak year that is 9,087 kWh, in a good one 12,583 kWh — 1,642 kWh per kWp.

That’s about 197% of a typical home’s yearly use (5,500 kWh).

Common questions

How much do solar panels produce in winter in Adelaide?

From May to August the system produces about 2,720 kWh, which is 25% of the year. The weakest month (June) gives roughly 600 kWh.

Is an east-west roof worth it in Adelaide?

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 Adelaide?

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.
