Aside from being the biggest city in Western Australia (WA) and the fourth-largest city in the whole country, Perth is the sunniest capital in the whole world! It is known as the “City of Lights” when Perth residents turned on their lights when John Glenn, the astronaut, passed over the area. In fact, residents experience an average of eight hours of sunlight every day, all year long. 

That said, it’s no wonder that Perth residents are taking advantage of that much sunlight by switching to solar.

The costs of solar panels in Perth have reduced significantly over the years. When determining the number of solar panels you should install for your Perth property, consider your roof and the amount your local electricity network will let you install. 

For most homes in WA, the ideal solar system size is 6.6 kW or PV panels with a 5 kW inverter. Additionally, you can install up to 33 per cent more panels than the inverter is rated at. 

Suppose you consume a lot of energy, or you are planning to add an electric vehicle or solar battery to your home in Perth, then you can install a bigger solar system. With this, we recommend you size up where possible. This is considering the increase in electrification, which will impact your future electricity needs. When you size up now, you can save a lot more money by installing a bigger system initially. 

Solar rebates and incentives in Perth, WA

Small-scale Technology Certificates (STC)

Perth homeowners with solar panels installed are entitled to rebates and incentives, including STC. If you have solar panels or a solar hot water system, you are eligible for STCs that you can trade on an open market or give to a solar installer in Perth to get a big discount on your solar system. 

The amount of STCs you get will depend on the supply and demand. Additionally, the number of STCs you get will also depend on the size of your solar system and location. 

Feed-in Tariff (FiT)

The FiT providers homeowners in Perth credit for every kWh of energy their solar system exports back into the grid. Your energy retailer will apply it and it will show as a discount off your electricity bills. Some energy retailers offer higher FiTs. With this in mind, it’s a good move to compare energy retailers.

The right solar system in Perth

When choosing a solar system in Perth, you need to ensure that you are getting the right one. To do this, you need to consider the following factors: 

  • Roof condition: Make sure your roof is in good condition before you have solar panels in Perth installed.
  • Roof angle: How your roof is angled is crucial when it comes to solar panel efficiency. Ideally, your roof should be tilted at the same angle as the latitude of your home’s location.
  • Energy consumption: Get an idea of your average energy consumption by checking your monthly energy bills. Doing so will help you determine the size of a good solar system in Perth. 
  • Surrounding shade: Trees on your property or in your neighbor’s yard may impact the efficiency of your solar system in Perth. Trim the trees as much as you can.

Do you need a solar storage battery in Perth?

A home solar battery storage system will let you store energy generated by your solar panels during the day. You can use this stored solar energy throughout the night or on cloudy days. Whilst a solar storage battery doesn’t come cheap, it brings a lot of benefits that outweigh its cost, such as: 


  • Energy independence: The electric grid isn’t that stable anymore, plus there is an increase in electricity rates. You can ride the waves with a solar battery storage that will reduce your dependency on the grid, which will make your home fully self-sufficient.
  • Blackout protection: Blackouts rarely happen in Perth, but when it does, it is a huge inconvenience. Many batteries, like the Tesla Powerwall, can power your home in Perth whilst your street doesn’t have power. Your solar panels will continue to charge your battery throughout the day; therefore, you have power during blackouts and throughout the night.
  • Cost savings: Participating in a Virtual Power Plant (VPP) can see you saving even more money because you will get credits for sharing the power stored in your solar battery in Perth back to the grid. 


Even better, there are many brands and types of solar batteries you have access to in Perth. 

Electric Vehicles (EVs) in Perth

Western Australia has subsidies in the form of a $59.1 million package, which includes $3,500 rebates for up to 10,000 buyers of new Battery-Electric Vehicle (BEV) and Fuel-Cell Electric Vehicles (FCEV). Additionally, there is a $22.6 million investment in infrastructure to support EV. 


Under this new package, the first 10,000 West Australians to buy a sub-$70,000 BEV or FCEV will get a $3,500 rebate from the WA government. The WA government also nominated a yearly fuel saving of $1,400 for the average motorist who switches from combustion power to a zero-emissions vehicle. 


There is also a $4 million fund for Public Transport Authority to trial the installation of EV charging infrastructure, that will provide up to 20 bays per car park with commuter charging access at four key stations. The remainder $2.9 million will be used to install eight new charging stations along National Highway 1. By 2027, WA will introduce a new distance-based road user charge of 2.5c per kilometre for BEV and FCEV. 


Finally, as part of the WA’s Home Plan incentive, the government offers a $200 rebate for home-charging an EV or plug-in hybrid. 


With the WA Government’s continuous efforts to reach net-zero, there will be more EV models to be launched. Here are the benefits of EVs: 


  • Lower costs: EVs are easier and more affordable to run and maintain.
  • Help meet the country’s emissions target: Australia is on a mission reach net-zero by 2050. You can be a part of this when you switch to an EV today.
  • More economic opportunities: Australia is the biggest exporter of lithium in the world, and EV batteries are mainly made of lithium. Your EV can help maintain the lithium industry.
