Warning signs

Is Your Perth Solar System Not Working Properly?

If your solar system is not producing expected output, shutting down, or behaving inconsistently, it may require structured solar fault finding.

Common issues include:

No Power Production

Solar system not producing power

Fault Codes

Inverter showing fault codes

Performance Drop

Sudden performance drop

Circuit Issues

Did you know?

Many solar faults are electrical or configuration-related rather than panel failure, meaning a targeted repair is often all that's needed to restore full performance. All fault finding and repair work is carried out by SAA accredited solar electricians.

Common questions

Frequently Asked Questions About Solar Fault Finding in Perth

Note: The federal STC solar rebate reduces each year as the scheme winds toward its 2030 end date. If you are considering a new solar system, act sooner to access the higher current rebate. See the Clean Energy Regulator for details, or call 1300 717 583 for current pricing.

Common causes include inverter faults or error codes, DC isolator failure (particularly in older Perth systems installed before 2009), tripped circuit breakers, loose or corroded connections, and in some cases panel damage. Energy Safety WA recommends that all solar electrical work be carried out by an expert electrician. A structured diagnostic inspection is required to confirm the cause. Guessing and replacing parts without diagnosis often wastes money and misses the real problem.
A significant drop in output can be caused by inverter faults, shade from new vegetation or structures, panel soiling (particularly common in Perth's dusty eastern suburbs), partial string failures, or DC isolator degradation. Compare your current output with your monitoring data from the same period last year. If the drop is sudden rather than gradual, it's more likely electrical than weather-related.
Inverter error codes indicate a fault condition that has caused the inverter to stop producing or go into safe mode. Common causes include grid voltage fluctuations on the Western Power network, insulation resistance faults, DC input issues, and internal hardware faults. The specific error code narrows down the cause. Our technicians review inverter logs and run live tests to accurately diagnose the issue.
Sudden faults are far more likely to be inverter, isolator, or wiring-related than panel failure. Panel degradation is gradual (around 0.5–1% per year under Perth's conditions), whereas inverters and isolators can fail quickly. We run diagnostic tests on both the panel strings and inverter to isolate the cause accurately, rather than assuming the more expensive component is at fault.
A standard residential solar fault finding inspection in Perth typically takes 1.5–3 hours depending on system size and fault complexity. We review inverter event logs, test electrical protection, measure string output, and assess physical components. After inspection, we provide a clear written report with findings and recommended corrective actions.
Yes. Coastal Perth suburbs, including Scarborough, Cottesloe, Fremantle, and Hillarys, experience salt-laden air that accelerates corrosion in electrical connections, mounting hardware, and DC isolator housings. We see higher rates of connection degradation and isolator failure in coastal areas, which is why regular maintenance inspections are particularly important for coastal Perth properties.
