Common questions

How much do solar panels produce in winter in Launceston?

From May to August the system produces about 2,185 kWh, which is 23% of the year. The weakest month (June) gives roughly 447 kWh.

Is an east-west roof worth it in Launceston?

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 Launceston?

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.
