Perth is one of Australia’s sunniest cities: Perth Airport averages 8.8 hours of sunshine a day (Bureau of Meteorology, 1993 to 2025). A system sized to your daytime usage lets you run more of your home on your own power instead of buying it from the grid. Whether it pays off for you depends on your usage, roof and bills, which your quote works through.

A common Perth home system pairs about 6.6kW of solar panels with a 5kVA inverter, which the WA Government treats as 5kW of generating capacity under the buyback scheme. The right size for your home depends on your electricity usage, roof space, single or three phase supply and Western Power’s connection rules.

Most residential installs are completed in a single day. Before installation, an Embedded Generation Connection application goes to Western Power for any new inverter system, and your installer can lodge it on your behalf. Grid approval typically takes a few weeks.

North-facing panels generally produce the most energy over a day in Perth. West-facing panels produce more in the afternoon, which suits the 3pm to 9pm buyback window and evening household use. Many Perth homes split panels across roof faces, and your design should show the expected output for each.
Service life, warranty and degradation are different things. Good quality modern panels should last at least 20 years, and many keep generating well beyond that.
The product warranty covers faults and is often 10 to 15 years, with some manufacturers offering 25 years or more. A separate performance warranty, usually 25 years, sets the minimum output the panels should keep. Output declines gradually over time rather than stopping, and your quote lists the warranty terms for the panels proposed.
New solar panel systems earn small-scale technology certificates (STCs) under the federal Small-scale Renewable Energy Scheme, which installers normally take off the upfront price. The number of certificates falls each year until the scheme ends in 2030. Home batteries can also qualify for the WA Residential Battery Scheme and the federal Cheaper Home Batteries Program.

Two programs may apply: the WA Residential Battery Scheme and the federal Cheaper Home Batteries Program. Eligibility depends on the current scheme rules, your electricity retailer and the battery and installation proposed, and we confirm what applies in your quote.
Under the WA Government’s Distributed Energy Buyback Scheme (DEBS), Synergy customers earn 10 cents per kWh for solar exported between 3pm and 9pm and a lower rate at other times. You or your installer apply to Synergy for the buyback rate when a system is installed or upgraded.

Solar panels only generate while the sun is up, so on their own they cannot run your home in the evening or overnight. How much of your electricity a system covers depends on its size, your roof and when you use power. A battery can store daytime surplus for the evening, and the grid supplies the rest.
A standard grid-connected solar system also switches off during a blackout for safety, so it does not provide uninterrupted power by itself.
Usually, yes. A battery is normally added to an existing system through AC coupling, which works alongside your current solar inverter. Whether it suits your home depends on your inverter, switchboard and network connection requirements, so we check your existing equipment before quoting.
If your system is old or small, we may recommend upgrading the solar at the same time.
Not automatically. Not every battery system supplies power during an outage. Backup needs a battery and inverter with that capability, installed and configured for it, and it may cover selected circuits rather than the whole home.
If backup power matters to you, tell us and we will quote a setup that includes it and explain what it will run.

To make solar panels more affordable, the government offers several rebates and incentives. Our team is extremely helpful in guiding you through the process of applying for these rebates, including the solar rebate offered in Western Australia.
The amount of power your solar system will produce depends on several factors, including the system size, the tilt angle and orientation of your panels, and the amount of sunlight your location receives.
