Generating solar power in Perth

Perth is the sunniest capital city in Australia. It receives an average of 5.34 hours of sunlight per square metre, per day (Bureau of Meteorology). The large amount of sunshine hours, together with competitive solar panel prices, make Perth one of the best cities in Australia to install a solar power system.

Perth solar panel output

System sizeSolar output
3kW13.2 kWh
4kW17.6 kWh
5kW22.0 kWh
6.6kW29.0 kWh
10kW44.0 kWh

Perth just outshines Brisbane as the best capital city in Australia to install and generate solar power. A 5kW system typically produces, on average, 22kWh of electricity per day and can payback in five years. The vast number of sunshine hours in Perth also means you receive a larger solar rebate than Melbourne residents.

Best angle for solar panels in Perth

If you can position your solar panels on an angle of 32°, you will maximise your system’s potential to generate solar energy. If your roof is tilt is not near to 32° you need not fret, unless you have a flat roof, your system’s output will still be adequate. If your roof is flat, you will need to mount your panels on at least 10° pitch so that they clean themselves.

The vector image shows an outline of a house with the sun shining on the angled roof. Text below explains that the ideal panel angle in Perth is 32° and anything between 10° to 45° is also fine for generating solar power.

Panel orientation

If you can do so, it is best to orient your panels to the North in Perth. A north-facing solar installation will maximise your solar panel output. Your system is still likely to be effective if your panels face the east or the west, particularly if your household consumes a large percentage of your electricity during the morning and evening peak periods.

Perth solar panel prices

The table below shows solar panel prices in Perth for different system sizes:

Perth solar prices

System sizeAverage prices
3kW$3,990
5kW$5,225
6.6kW$6,270
10kW$9,500

A good-quality 6.6kW system will cost you between $6,000 – $8,500 in Perth. There are advantages to selecting the best quality solar panels, even though they cost more. If not the best, then try to avoid buying cheap solar panels that come with shorter warranties without a premium placed on the installation.

Federal government solar rebate

All Perth residents can receive the Australian solar panel rebate, so long as you install components that the Clean Energy Council has approved; and an accredited installer installs them. Your rebate can be as much as $2,520 for a 6.6kW system. Often the rebate is already factored into the price that you get quoted.

Perth residents also receive feed-in tariffs for exporting their excess solar energy back to the grid.

The risks of buying low-cost solar in Perth

Selecting a system and solar company to perform the installation is not just a matter of comparing prices. The WA Commissioner for Consumer Protection, David Hillyard, reported more than 200 complaints from consumers in the past 12 months.

Hillyard recommends, “Get quotes from several reputable companies that have proven experience and a good track record. Read online reviews and feedback about suppliers before signing a contract. Cheaper systems may not last as long so you need to take that into consideration.

We list some of the risks typically associated with cheap systems:

  • System may not last as long as it should
  • The installer company may go out of business
  • The solar system may not perform as expected

Perth solar companies

When buying solar panels for your house, you need to avoid the temptation to make a decision purely based on price. Selecting the right company to install your system and advise you on suitable components is essential. We list some of the key points to look out for in a good solar company:

  • Ensure they use CEC accredited installers
  • Ask and compare the solar panel warranties
  • Do they provide a full system warranty?
