Solar Repairs Sydney

If your solar system is underperforming, throwing inverter errors or has stopped exporting, Sydney Power Group can find the fault and fix it. Our licensed electricians diagnose the whole system — panels, wiring, isolators, inverter and metering — rather than guessing at one component.

We service systems across Greater Sydney, whether we installed them or not, and repair to Australian standards so your system stays safe and compliant.

Common solar faults we fix

Underperformance can come from a failing inverter, degraded panels, string dropouts, dirty or shaded arrays, or a wiring and connector fault. Rooftop isolators are a frequent culprit — they weather badly and can cause intermittent faults or complete shutdowns.

We also see metering problems where a system produces power but isn't crediting export correctly, which often traces back to how the meter is configured — something we can correct as a solar meter upgrade.

Diagnosis, not guesswork

We test methodically: checking inverter logs and error codes, measuring string voltages and currents, and inspecting isolators and terminations. That tells us whether you need a component replaced, a repair, or a wider solar installation review.

Where an inverter is beyond economic repair, we'll explain your replacement options honestly, including battery-ready and hybrid inverters if you're considering adding a battery.

Safe, compliant repairs

Rooftop DC systems carry real hazards, so all work is done by licensed electricians following correct isolation and safety procedures, with faulty parts brought back to standard.
