Solar panels in Sydney: All you need to know
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:
| 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.
Solar panel prices in Sydney
Sydney is arguably Australia’s most competitive location for solar panel installations, and prices reflect this. Prices in Sydney are on the whole cheaper than they are in Brisbane.

Government solar rebate
All New South Wales residents can get a solar rebate when they buy solar panels, providing the components are approved by the Clean Energy Council and the installation is carried out by a CEC accredited installer. The federal rebate can reduce the cost of your solar panels by as much as $1,920 for a 5kW system, or $2,520 for a 6.6kW unit. There is currently no state rebate on offer for New South Wales residents.
New South Wales feed-in tariffs
New South Wales feed-in tariffs vary by retailer. Expect to receive anywhere between 5 – 12c depending on your retailer and the electricity plan you are on. Some retailers offer a maximum feed-in tariff that can be as high as 15 – 20c per kWh, but they normally have special conditions.
Cheap solar in Sydney
The Sydney market is particularly competitive; beware of companies that are taking shortcuts and quoting prices that seem too low. We strongly recommend that you do not select your system based on price alone. If you do experience any issues when installing solar panels, you can contact the Energy & Water Ombudsman NSW and lodge a complaint.
