Solar Energy Company in Perth Metropolitan
A guide to choosing a solar energy company in Perth Metropolitan, with 193 installers compared on licensing, panel and inverter quality, and workmanship.
What solar installers actually do
A solar energy company designs and installs rooftop (or ground-mount) solar systems, and often battery storage alongside them. That covers a site assessment of your roof orientation, shading and switchboard, a system design sized to your household or business usage, supply of panels and an inverter, the physical install and electrical connection, and paperwork such as Small-scale Technology Certificate (STC) rebate claims and grid connection approval with Western Power. Many also handle ongoing monitoring, fault callouts and warranty claims once the system is running.
With 193 companies operating across Perth Metropolitan, quality varies a lot even though the underlying products (panels, inverters, mounting rails) come from a fairly small pool of manufacturers. The difference between a good job and a poor one usually comes down to the installer, not the brand on the panel.
What to check before you sign
- Clean Energy Council (CEC) accreditation for the installer, since this is required for STC rebate eligibility
- An electrical contractor's licence and public liability insurance
- A written quote that names the exact panel and inverter model, not just wattage and brand
- Product and workmanship warranty terms, and whether the installer is still likely to be trading in 10 years to honour them
- Reviews that mention post-install service, not just installation day

Common questions about solar energy company
- How much does a solar system cost in Perth Metropolitan?
- A typical residential system after the federal STC rebate is applied often lands somewhere between roughly $3,500 and $8,000 depending on system size (a common range is 6.6kW to 10kW), panel and inverter brand, and roof complexity. Battery storage adds several thousand dollars more. Always get at least three itemised quotes, since the same size system can vary significantly in price between installers.
- How often does a solar system need servicing?
- Most manufacturers and installers recommend a visual check and panel clean every 1-2 years, plus a proper electrical inspection every 2-4 years to check connections, mounting and inverter performance. Systems near the coast or under trees may need more frequent cleaning due to salt spray or debris buildup.
- What should I expect on installation day?
- A typical residential install takes one day for the crew to mount panels, run cabling, fit the inverter and connect to the switchboard, followed by testing and a walkthrough of the monitoring app. Grid connection approval from Western Power can take anywhere from a few days to a few weeks after that before the system is fully switched on.
- How can I judge the quality of a solar installer?
- Look for CEC accreditation, ask how long they've been trading locally, and check whether their warranty is backed by an Australian office or distributor rather than an overseas manufacturer only. Neat cable runs, proper roof penetration sealing and a clear handover of documentation are good signs of a careful installer.
