How much will solar panels produce in Queenstown?

A 5 kWp system facing north at 35° tilt in Queenstown produces about 6,405 kWh a year. In a weak year that is 5,364 kWh, in a good one 7,445 kWh — 1,281 kWh per kWp.

That’s about 91% of a typical home’s yearly use (7,000 kWh).

Common questions

How much do solar panels produce in winter in Queenstown?

From May to August the system produces about 1,209 kWh, which is 19% of the year. The weakest month (June) gives roughly 233 kWh.

Is an east-west roof worth it in Queenstown?

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 Queenstown?

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.
