How much will solar panels produce in Canberra?

A 6.6 kWp system facing north at 35° tilt in Canberra produces about 10,416 kWh a year. In a weak year that is 8,631 kWh, in a good one 12,201 kWh — 1,578 kWh per kWp.

That’s about 189% of a typical home’s yearly use (5,500 kWh).

Common questions

How much do solar panels produce in winter in Canberra?

From May to August the system produces about 2,826 kWh, which is 27% of the year. The weakest month (June) gives roughly 563 kWh.

Is an east-west roof worth it in Canberra?

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 Canberra?

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.
