How much will solar panels produce in Alice Springs?

A 6.6 kWp system facing north at 35° tilt in Alice Springs produces about 12,586 kWh a year. In a weak year that is 10,516 kWh, in a good one 14,656 kWh — 1,907 kWh per kWp.

Common questions

How much do solar panels produce in winter in Alice Springs?

From May to August the system produces about 4,297 kWh, which is 34% of the year. The weakest month (January) gives roughly 951 kWh.

Is an east-west roof worth it in Alice Springs?

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 Alice Springs?

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.
