Choosing a residential solar supplier in Perth
A residential solar system is more than a set of panels on the roof. The supplier designs the array around your roof and usage, supplies the panels and inverter, handles the grid connection application with Western Power, and installs and commissions the system. Many also offer battery storage, either at install or as a later add-on.
Perth's sunshine suits solar, but quality still varies a lot across the businesses listed here. Look for Clean Energy Council accredited installers, named panel and inverter brands with clear product and performance warranties, and a written quote that states system size in kW and expected output. Check how the roof layout (north, east or west facing) affects yield, and whether the inverter is sized for a future battery or EV charger. A local office matters too, since you will want someone nearby when warranty work comes up.

Common questions about residential solar panel systems
- How much does a home solar system cost in Perth?
- As a rough guide, a 6.6 kW system with a 5 kW inverter typically costs around $4,000 to $7,000 after the federal small-scale technology certificates discount, depending on panel and inverter brand. Batteries add several thousand dollars more. Always compare itemised quotes.
- How long does a solar system last?
- Panels commonly carry 25-year performance warranties and often keep working beyond that, with gradual output decline. Inverters usually need replacing after about 10 to 15 years, so check the inverter warranty length.
- What happens on installation day?
- Expect a site check first, then one to two days of work for a typical home: mounting rails, panels, inverter, and wiring to your switchboard. The installer lodges the grid connection paperwork, and the system is switched on once the network operator approves it.
- How can I tell if an installer is good quality?
- Confirm Clean Energy Council accreditation, ask for the specific brands and warranty terms in writing, and check recent reviews for after-sales service. Be cautious of pressure tactics or quotes far below others.
