Adelaide solar power

Adelaide suffers from the highest electricity prices in Australia. Fortunately, Adelaide also receives an abundance of sunshine, making it an ideal location to generate solar power. The combination of high electricity prices and ample sunshine mean that you can pay back the cost of your solar system within 4-5 years.

Adelaide solar power output
3kW Solar system 12.6kWh
4kW Solar system 16.8kWh
5kW Solar system 21.0kWh
6.6kW Solar system 27.7kWh
10kW Solar system 42.0kWh

Many variables affect solar panel output at your property, so we recommend using our detailed solar calculator that can generate results specifically for your rooftop, and you can weigh up whether or not solar is worth it. We explore some of the solar variables for your property below.

North facing orientation is best

The ideal scenario for generating solar in Adelaide is if your rooftop faces North, year-round, this orientation will produce the most power. You can still make significant savings if your rooftop faces east or west, particularly if you use the majority of your electricity during the early morning and late afternoon peak periods.

The image shows a compass symbol and explains that a North orientation is best in Adelaide. East and West can also produce good solar output while South is best avoided.

Roof pitch for maximum solar exposure

The tilt of your solar panels does affect output, though the difference between the ideal angle and one 25° off is typically less than 10%. In Adelaide, a roof pitch of 35° is ideal for year-long solar gain, while a higher roof pitch will mean you can generate more power in the winter months.

The image explains that a roof pitch is 35° is ideal in Adelaide, but anywhere between 10 - 45° has little impact on solar output.

Solar panels prices in Adelaide

A 6.6kW solar system in Adelaide typically costs between $5,500 – $8,500. The price range includes all components, the cost of installation, your solar rebate and GST. You will find lower prices for solar in Adelaide, and some may be good systems, but we recommend you pay extra for a reliable and longer-lasting installation. If you want the best solar panels, add another 10% onto the high range of these prices. The table below shows average prices in Adelaide for different system sizes.

Beware bargain basement deals

It is important to avoid the temptation to make select a company and solar components on price alone. Systems vary, as does the quality of installation and the length of warranties; it is not an apples vs apples comparison. To avoid the potential pitfalls that cheap systems can bring, compare and consider the following:

  • The quality of the solar panels
  • The quality of the inverter and cabling
  • The product warranties of all components
  • The accreditation levels of the solar company

South Australian battery scheme

The South Australian government’s Home Battery Scheme is now closed. If you are interested in a battery, we recommend you investigate the cost of battery storage. You can use our battery calculator if you already have solar panels.

Adelaide feed-in tariffs

In Adelaide, your electricity retailer determines the feed-in tariff you receive for the excess solar you export to the grid. Due to the higher electricity prices, retailers generally offer a feed-in tariff between 5.5 – 8.5c, which, is marginally higher than you what residents in Sydney receive.
