Pricing guide
Cost depends mainly on whether the issue is a straightforward diagnostic and minor repair or requires major component replacement. Systems with batteries, microinverters or monitoring integrations typically take longer and may need specialist parts or commissioning. After-hours attendance and any required certification or inspection can also increase the final cost.
Repair versus major replacement
A simple reset or minor repair is usually quicker than a full inverter or multi-panel replacement, which adds removal, fit and commissioning tasks.
Parts type and availability
Replacing major components like inverters or panels often expands scope and may require ordering specific parts, affecting timing.
Access and working at height
Roof access, safe ladder access and difficult rooftop conditions generally increase labour time and safety requirements.
Timing and certification requirements
After‑hours attendance typically costs more and major works often trigger certification or inspection steps that affect time and scope.
Estimated range
$627 – $2,360
Default scope: No output, tripping, or a fault light on the inverter
