Perth solar panels: Prices and installer companies
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.
|3kW Solar system||13.2kWh|
|4kW Solar system||17.6kWh|
|5kW Solar system||22.0kWh|
|6.6kW Solar system||29.0kWh|
|10kW Solar system||44.0kWh|
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.
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:
A decent-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 $3,000 for a 5kW 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
