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.

Frequently asked questions

Do solar repairs require a licence?
Yes — solar electrical work must be carried out by a licensed installer in Australia, and licensing is mandatory. Licensed installers are usually familiar with any certification or inspection obligations associated with repair or replacement work.
How long does diagnosis and repair usually take?
Standard single-visit diagnostics and minor repairs are typically completed within one visit and often take a few hours. Systems with battery integration, monitoring issues or major component replacement can take significantly longer or may require follow-up visits.
Will a replacement require inspection or paperwork?
Major replacements often trigger certification or inspection requirements and can add time to the job. These steps are commonly arranged by the installer but may affect the overall scope and scheduling.
What information should I give before the visit?
Provide details such as inverter model, whether you have batteries or hybrid systems, any monitoring app error codes, and clear photos of the installation and access. This information usually helps installers prepare and may reduce diagnostic time.
