Solar panel service and safety checks in Traralgon
Solar panel service in Traralgon: what a licensed electrician checks every two years, why older systems carry most fire risk, and what to ask for.
A solar panel service in Traralgon is an electrical safety check of a system that still works, carried out by a licensed A Grade electrician who is employed by a Registered Electrical Contractor. Energy Safe Victoria and Solar Victoria recommend one at least every two years. The service covers wiring, switches, isolators, the inverter’s fault history and the condition of the whole installation, which a panel wash does not.
This page covers routine servicing only. If your system has already stopped producing, shows an error or has visible damage, the solar repairs page is the better starting point.
Why does a solar system need a service if it still produces power?
Most of the parts that fail on a rooftop system fail quietly. A DC isolator can let water in for years before it trips or overheats. A cable rubbing on a tile edge or a rail loses its insulation slowly. Connectors loosen with daily heating and cooling. The inverter can log the same fault hundreds of times while the display still shows a reasonable daily total.
Energy Safe Victoria’s records give the strongest reason to book a check. In the Be solar safe reminder published on 29 September 2026, Energy Safe and Solar Victoria said that systems four years or older make up about one in five rooftop systems, yet account for almost two thirds of the solar-related house fires Energy Safe has recorded since July 2021. Most of those fires happened in the warmer months, so spring is a sensible time to have an older system looked at before summer. The full reminder is on the Solar Victoria website.
Warning signs that should move a service forward rather than wait for the two-year mark:
- output lower than the same month last year, with similar weather
- a burning or hot plastic smell near the inverter, isolator or meter box
- buzzing, crackling or clicking that was not there before
- an inverter that restarts or drops off during the day
- discoloured or cracked isolator covers on the roof or wall
If you notice smoke or crackling, stay clear of the equipment and call emergency services rather than sending an enquiry.
What does a licensed electrician check during a solar service?
Energy Safe Victoria publishes the items a licensed electrician should look at. The list below follows its solar safety guidance, with notes on what each check involves in practice.
| Energy Safe check | What it means on a Traralgon roof or wall |
|---|---|
| No parts deteriorated or corroded | Rails, clamps, earthing and isolator housings inspected for rust, cracking and UV damage |
| Switches have no defects | AC and DC isolators operated and inspected, covers opened where the design allows |
| Wiring not damaged or deteriorated | Cable runs on the roof and in the roof space checked for chafing, sagging and animal damage |
| Electrical checks of all components | Tests that the array and inverter are operating as intended, with readings recorded |
| Fittings and cables securely attached | Conduit, glands and cable ties checked so nothing lies loose on the roof sheet or tiles |
| Inverter display reviewed for recorded faults | Fault log read and the history explained to you before anything is cleared |
| Access to isolator switches not impeded | Shrubs, stored items and later building work cleared away from switches |
| Shutdown and isolation procedure clearly displayed | Signage at the switchboard and inverter present and readable |
| Panels, vents, inverter and battery free of leaf litter and debris | Leaves and nesting material removed from around equipment and vents |
Ask the provider to give you a written record of what was checked, the test readings and anything found. If a component needs replacing, that becomes a separate quote. Inverters at the end of their life are covered on the inverter replacement page.
Is panel cleaning the same as a solar service?
No. Some businesses advertise solar servicing when the work is a panel wash. Energy Safe Victoria describes these as nothing more than a cleaning service, and its guidance says a service must be done by a licensed electrician. Solar Victoria adds that panel cleaning alone is not an electrical safety check, and that cleaning done the wrong way can let water into components that have already deteriorated, which raises the risk of a fault.
| Panel clean | Electrical service | |
|---|---|---|
| Who does it | Anyone, including a cleaning business | Licensed A Grade electrician employed by a Registered Electrical Contractor |
| What it covers | Glass surface of the panels | Wiring, isolators, inverter, fittings, signage, tests and debris |
| Finds a failing isolator | No | Yes, that is part of the inspection |
| Paperwork | Usually none | Written findings, and a Certificate of Electrical Safety if electrical work is done |
When a quote says “service”, ask who will be on the roof and check that person’s licence. Energy Safe keeps its public registers for Registered Electrical Contractors and licensed electrical workers. The about page explains how enquiries from this site reach an independent business, which then quotes and carries out any service itself.
How does a solar service usually run?
- Before the visit, the provider asks for the install year, inverter brand and model, whether a battery is fitted and when the system was last serviced.
- On arrival the electrician follows the shutdown procedure and isolates the system before touching anything.
- The roof inspection covers panels, rails, cable runs and rooftop isolators. On a two storey home or steep roof this may need extra access equipment, which affects the price.
- Ground level checks cover the inverter, its fault log, the switchboard connection, any battery enclosure and the signage.
- Electrical tests are carried out and recorded.
- The system is restarted, its operation confirmed and the findings explained to you, with photos of anything that needs attention.
What should you keep clear of inverters and batteries?
Energy Safe Victoria asks households not to store anything against inverters and batteries, and names wood piles, paint and other flammable liquids. That matters in Latrobe Valley homes where the inverter is often mounted on a garage or carport wall that also holds the firewood stack, a lawn mower fuel can or leftover paint tins. Moving those items costs nothing and removes a fuel source right beside the equipment most likely to overheat. A good service visit will point out anything stored too close.
What does a solar service cost in Traralgon?
A national guide from Why Solar, published 1 March 2026, puts a full system health check and fault diagnostic at $150 to $300 per visit. A Traralgon quote will move around that band with roof height, the number of rooftop isolators, whether a battery is included and travel from the provider’s base. Parts and repair work found during the service are quoted on top. A request to book a solar health check that lists the inverter model and install year lets the provider price the visit before arriving.
Who should service a Solar Homes system?
If your panels or battery went in under the Solar Victoria Solar Homes Program, Energy Safe Victoria recommends contacting the retailer that supplied it first. Program retailers and installers had to meet set safety and quality standards, and the retailer may still be responsible for parts of the installation. If that retailer no longer trades, any licensed electrician employed by a Registered Electrical Contractor can carry out the service.
Which Valley systems are most overdue for a service?
Many Latrobe Valley homes took up rooftop solar early, and a fair share of those systems are now well past the four-year mark that Energy Safe’s figures single out. Towns with older housing, such as Churchill, often pair an ageing system with an older switchboard, and a careful electrician will look at both. If a service turns up a tired isolator or damaged cabling, the follow-up work sits under solar repairs.
Next step: send a solar service enquiry
Put four things in the enquiry so the provider can quote accurately: the year the system was installed, the inverter brand and model (a photo of the label works), the date of the last service if you know it, and whether a battery is fitted. Add your suburb and the number of storeys. Then send a solar service enquiry and an independent local electrician will contact you about the visit.
Frequently asked questions
- How often should a solar system in Traralgon be serviced?
Energy Safe Victoria and Solar Victoria recommend a service at least once every two years. Book sooner if output drops, you smell burning plastic near the inverter or isolator, or you hear new buzzing or crackling.
- Can I service my own solar panels?
No. Electrical checks on a solar system have to be done by a licensed A Grade electrician working for a Registered Electrical Contractor. Hosing dust off the glass from the ground is the only upkeep a homeowner should attempt, and even that is not a safety check.
- Does a solar service need a Certificate of Electrical Safety?
An inspection on its own does not normally produce one. If the electrician carries out electrical work during the visit, such as replacing an isolator or cable, you should receive a certificate for that work.
- What should I ask before booking a solar service?
Ask who will be on the roof, check their licence on the Energy Safe public register, and ask what the visit covers. A proper service includes the inverter fault log, isolators, wiring, fittings, signage and debris, with written findings at the end.
- My system went in under Solar Homes. Who should service it?
Energy Safe Victoria suggests contacting the retailer that supplied the system first. If that business has closed, any licensed electrician employed by a Registered Electrical Contractor can do the service.
