Solar power in Sydney

Conditions in Sydney are well suited to generating solar power. A typical 5kW system can generate around 19.6kWh per day, more than is possible in Melbourne. The table below shows the average output of different size solar systems in Sydney:

Solar power output in Sydney
3kW Solar system: 12.0kWh
4kW Solar system: 16.0kWh
5kW Solar system: 20.0kWh
6.6kW Solar system: 26.4kWh
10kW Solar system: 40.0kWh

There are local variants that will affect the output of your solar panels in Sydney:

Panel angle

The best angle to install your panels in Sydney is 33.9°, which is the same angle as the latitude of the city. If you have a flat roof, you will need to mount the panels on an angle so that they clean themselves when it rains. Otherwise, a roof pitch either side of 33.9° will still generate a decent amount of solar.

Panel orientation

For all locations in Australia, including Sydney, it is best to orient your panels to the north. If you have an east/west roof orientation, your solar panels can still generate good output, particularly if your consumption habits align with the morning and late afternoon periods when your panels are generating power.

Shading of panels in Sydney

It is best to install your panels to avoid any shading issues. If it is not possible to do so, microinverters and power optimisers can mitigate the effect of shading on your panels, though both solutions add to the cost of your solar system.
