7 Years Later – We Found Problems!

 

The Background: Installation Problems From Day One

On 13 October 2026, our team from Verve Electrical and Solar Rescue attended a residential property in Chirnside Park to carry out solar maintenance. During our conversation with the homeowner, we discovered that the solar system had experienced several problems following its original installation approximately seven years earlier. Fortunately, the installation had been selected for a random compliance audit, which identified defects that the homeowner may otherwise never have known existed. The original installing electrician was subsequently required to return to the property and rectify those issues.  

What We Discovered During Our Solar Inspection

Despite the previous audit and rectification work, our electricians discovered loose electrical connections within the solar installation. These connections had remained an issue for years without the homeowner being aware of the potential danger. We identified the loose connections during our inspection and rectified them on the spot, addressing a potential electrical safety hazard.

Why Are Loose Solar Connections So Dangerous?

Unlike many household electrical appliances, solar systems generate electricity whenever sufficient sunlight is available. Loose electrical connections can create increased electrical resistance, potentially resulting in:

• Excessive heat developing around electrical terminals and connections.
• Melting or deterioration of rooftop DC isolators and other electrical components.
• Electrical arcing, which can create a serious fire hazard.
• Premature failure of equipment and interruptions to solar generation.
• Increased risk of damage to the property and surrounding roof structure.

In severe circumstances, overheating or arcing at faulty connections can ignite nearby materials and lead to a rooftop fire. Although we cannot say with certainty that this particular installation would have caught fire, identifying and rectifying these loose connections eliminated a known hazard before it could potentially develop into something much more serious. This is precisely why solar maintenance is about far more than simply checking whether your electricity bills are coming down.  

Solar Panel Cleaning Is Important, but Cleaning Alone Isn’t Enough

Many homeowners associate solar maintenance with washing dirt, dust and bird droppings from their panels. While solar panel cleaning is an important part of maintaining the system’s performance, it does not replace a professional electrical inspection. Over time, environmental contaminants can accumulate on solar panels, reducing the amount of sunlight reaching the solar cells and potentially decreasing energy production. Professional solar panel cleaning can help:

• Remove built-up dirt, grime, bird droppings and other contaminants.
• Restore energy production where soiling has reduced performance.
• Maintain the efficiency of your investment.
• Identify visible panel damage or deterioration during the cleaning process.

However, clean solar panels do not necessarily mean a safe solar system. The loose connections we discovered in Chirnside Park are a perfect example. A cleaning service alone would not necessarily have identified these faults. This is where engaging a qualified electrical contractor makes a significant difference.

How Often Should Solar Systems Be Serviced?

Energy Safe Victoria recommends that residential solar installations be professionally inspected and serviced by a licensed A-Grade electrician at least once every two years. This is particularly important for older systems, where electrical components have been exposed to years of changing temperatures, moisture, sunlight and other environmental conditions. A comprehensive solar electrical safety inspection should include appropriate checks of:

• Rooftop and inverter DC isolators.
• Electrical connections, terminations and associated wiring.
• Solar panels, connectors and mounting equipment.
• Inverter operation and recorded faults.
• Signs of overheating, corrosion, moisture ingress or physical deterioration.
• Electrical safety and system performance through relevant testing.

At Verve Electrical and Solar Rescue, we believe homeowners should also receive clear documentation of the inspection, including findings, relevant testing and photographic evidence. That way, customers understand the condition of their system and have a record of any repairs or recommendations.

Our Chirnside Park Customer Was Fortunate

What makes this case particularly concerning is that the system had already undergone a compliance audit and subsequent rectification work. Despite those earlier interventions, we were still able to identify electrical defects seven years later. It highlights an important reality: a solar system passing an inspection or having faults repaired in the past does not guarantee it will remain safe indefinitely. Electrical connections can deteriorate, equipment can age, and faults can develop without any obvious warning to the homeowner. In this instance, our team identified and corrected the loose connections before they could develop into a more serious problem. For the homeowner, this meant greater confidence in the ongoing safety of their solar installation.

Protect Your Solar Investment With Verve Electrical and Solar Rescue

Solar panels are designed to operate for decades, but that doesn’t mean they should be left without maintenance. Whether your installation is two years old or ten years old, regular solar servicing and appropriate panel cleaning are important investments in both electrical safety and system performance. At Verve Electrical and Solar Rescue, we offer professional solar electrical inspections, fault finding, maintenance and solar panel cleaning services across Melbourne’s eastern suburbs, including Chirnside Park, Mooroolbark, Lilydale, Croydon, Ringwood and surrounding areas. We don’t just clean your panels. We understand the electrical systems operating behind them. When was the last time your solar system was professionally inspected? If it has been more than two years, contact Verve Electrical and Solar Rescue to arrange a professional solar maintenance and safety inspection. Because preventing an electrical fault is always preferable to dealing with the consequences of one.
