Solar Panel Repair near you

Heat is the dominant factor. An inverter mounted on a west-facing wall in full afternoon sun, or in an unventilated garage, runs hot for years and its electronics age accordingly. The same heat cycles the connectors and enclosures on the roof, and it is the repeated expansion and contraction rather than any single event that works a poorly seated connector loose.

Water and wildlife come next. Enclosures and conduit on an Australian roof take driving rain, hail and ultraviolet for a decade, and the seals that were adequate at installation stop being adequate. Birds nest under arrays, possums and rodents chew cable, and the mess accumulates out of sight because nobody looks at a roof they are not on.

Shading and soiling are the slow causes. A tree that was small at installation is not small now, a new building next door casts a shadow that did not exist, and dust, salt or bird droppings build on the modules. Each of these reduces output gradually enough that nobody notices until the year-on-year comparison is made, which is the argument for actually looking at the monitoring data occasionally.

A photovoltaic array generates whenever daylight falls on it. Switching the system off, or turning off the main switch at the board, stops the alternating-current side; the direct-current conductors between the modules and the isolation point remain live. That is the single fact that makes solar repair different from other electrical repair, and it is why the work is done by people trained specifically for it.

It is also why nothing about a solar system is a homeowner task, including the things that look harmless. Do not open an inverter, an isolator or any enclosure. Do not attempt to clean modules from a roof: it is a work-at-height activity on a slippery surface with live equipment on it, and the injuries from falls here are not minor. If a module is cracked, if an enclosure is damaged or if there is any sign of heat or burning, isolate what you can from the ground or at the switchboard and call an accredited professional.

After a storm, keep everyone off the roof entirely, including to look. Damaged modules and damaged cabling in a wet environment are exactly the combination that makes a rooftop dangerous, and the assessment is a job for someone with fall protection and test equipment.

The decision usually turns on the inverter, because it is the component with the shortest service life and the one whose failure stops everything. Replacing an inverter on an otherwise healthy array is a common and sensible repair, but it is not always a straight swap: a newer inverter must suit the array as it is configured, and it may have to satisfy current requirements for grid-connected equipment, which older systems did not have to meet.

Panel replacement is harder than it sounds for a different reason. Modules that match a decade-old array are often no longer made, and mixing dissimilar modules in a string can cost more output than the damaged module did. Where several modules have failed on an old array, partial replacement can be the more expensive answer over time.

The third factor is the roof itself. If the roof is due for replacement in the next few years, removing and refitting an array is a significant cost that is much cheaper done once. Where an old system is failing and the roof is tired, the honest advice is often to plan the two together rather than repair now and dismantle later.

Working on a grid-connected solar installation is licensed electrical work, and it is the kind most often offered by somebody not entitled to do it, because a roof looks like a place nobody is checking. Energy Safe Victoria's position is that unqualified electrical work is illegal as well as extremely dangerous, and an array that cannot be switched off while the sun is on it is the least forgiving place in a house to test that proposition.

Beyond the licence, grid-connected solar carries its own accreditation expectations, which is why service companies quote an accreditation number alongside a licence number. Ask for both, and ask which individual attending holds them, not just which company does.

A repair that alters the installation is not a neutral event administratively. Replacing an inverter with a different model, changing the array configuration or adding capacity can require the compliance paperwork for altered work, and can require the local distribution network business to be notified or to approve the change, because the connection agreement describes the system that was approved. Ask the repairer who is handling that notification before the work is booked, not after the system is back on.

Solar is a market where companies come and go, and many owners discover at the point of failure that the business named on their warranty no longer exists. That is frustrating but not fatal to your rights: the ACCC says a manufacturer's warranty is an extra promise that applies in addition to your consumer rights and cannot replace, change or take them away, so a failed component may still be a consumer guarantee claim against the manufacturer or importer even when the installer has gone.

The guarantees that matter are acceptable quality and durability for the equipment, and care and skill for the installation. Durability is the relevant concept for solar, because the expectation a reasonable consumer would hold for equipment sold as a long-life rooftop system is not the same as for a kettle. Keep the original quote, the installation paperwork, the certificates and the monitoring history, because a claim is much stronger with production data behind it.

On LokalMatch you describe the system, its age, what the monitoring shows and your postcode in one request, and solar service companies covering that postcode contact you; the requests they receive are what they pay for. LokalMatch does not carry out repairs, does not set prices and does not vet, rank or recommend anyone who responds, so checking the licence and the accreditation remains your job.
