Common Solar Questions
How long does a solar installation take from enquiry to switch-on?
Most home installs follow a similar path: an initial enquiry and quote, a site visit or remote roof assessment, Western Power approval, then the physical install (often completed in a day for a standard system), followed by inspection and grid activation. The physical work is usually the quickest part; approvals and scheduling make up much of the timeline. For a full breakdown of each stage, see our guide on how long a solar installation takes from enquiry to activation.
How many panels does my Perth household actually need?
System size depends on your daily electricity use, roof space, orientation and budget, not a one-size-fits-all number. A good starting point is reviewing 12 months of your power bills to understand daily consumption and when you use it. We assess this alongside your roof during the quote.

Which areas of Perth do you cover?
We work with homeowners right across the Perth metro area, from northern and southern suburbs through to coastal and eastern areas. Coastal homes sometimes need extra consideration for salt air and corrosion-resistant hardware, which we factor in during assessment. If you’re unsure whether we reach your suburb, contact us and we’ll confirm availability for your location.
How far in advance should I book an installation?
Booking a couple of weeks ahead usually gives you a good choice of dates, though this varies with demand and the time of year. Part of the timeline is outside anyone’s direct control, since Western Power connection approval must be in place before activation. Getting your quote sorted early helps keep things moving. Reach out to Perth Solar Power Installations to check current lead times.
Do I need to be home on installation day?
It helps to have someone available at the start and end of the day so the team can access the switchboard, discuss inverter placement and confirm Wi-Fi monitoring setup. There may be a short power interruption while the system is connected. You don’t need to hover throughout, but being contactable is ideal. We’ll explain exactly what to expect and how to prepare when your install is scheduled.
What's the difference between grid-connected, hybrid and off-grid setups?
A grid-connected system feeds excess power back to the grid and has no battery. A hybrid system adds battery storage so you can store daytime solar for evening use, while staying connected to the grid. Off-grid systems rely entirely on solar and batteries with no grid link, and suit specific situations. The right choice depends on your goals and usage. Learn more about which solar setup suits a Perth home.
How does the upfront solar rebate work in Perth?
Eligible home solar systems can access Small-scale Technology Certificates (STCs), a federal incentive typically applied as an upfront discount on your system price rather than a separate payment you chase later. The value depends on system size, location and the year of install. It’s usually handled on your behalf as part of the process. For a fuller explanation, see our guide on how Perth’s upfront solar rebate works.
Is a home battery worth adding in Perth?
It depends on your evening energy use, whether you want backup during outages, and how current rebates and buyback rates affect the numbers. Batteries store daytime solar for use after dark, reducing reliance on the grid during peak periods. With WA rebate schemes changing the maths, it’s worth running the figures for your household. Read more about whether a home battery is worth it in Perth.
How do you price a solar system, and how do I get a quote?
Pricing depends on factors like system size, panel and inverter choice, roof type, single or double-storey access, and whether you’re adding battery storage. Because every home is different, we assess your roof and electricity usage before providing a figure. Applicable rebates are usually factored in upfront. To get started, get in touch with your recent power bill handy and we’ll discuss options suited to your home.
How do I know if my older solar system needs upgrading?
Common signs include falling generation for the time of year, an ageing inverter showing fault codes, a system too small for your current usage, or wanting to add battery storage or EV charging. Many early-2010s Perth installs are now reaching the point where upgrading makes sense. We can review your existing setup and advise the right path. Learn more about telling if your older solar system is ready for an upgrade.
