Is Your Solar System Storm-Ready?
Extreme winds and “La Niña” style storms across Adelaide are putting immense strain on rooftop solar systems. While these systems are designed to be outdoors, the combination of torrential rain and gale-force winds can create hidden faults that compromise both safety and efficiency.
At Sharpe Trade Services, our trusted and experienced in-house technicians are seeing a rise in weather-related issues. Since 1970, we have been serving generations of the same household families, and we know that “detective work” after a storm is the only way to ensure your investment is still making you money.
Common Storm-Related Solar Faults
Our techs are currently identifying several issues caused by the recent “topsy-turvy” weather:
- Loose Cabling: High winds can snap aged plastic clips, leaving high-voltage DC cables to rub against your roof or gutters.
- Water Ingress: Heavy rain can find its way into electrical connections or the DC isolator switch, leading to “Isolation Faults” that shut your system down.
- Storm Grime: Dust, leaves, and debris can stick to wet panels, creating “hotspots” that reduce total energy generation.
The Isolator Solution
The rooftop DC isolator is a vital safety component, but it is also the most vulnerable to water damage. As part of our comprehensive solar service, Sharpe techs can install a weatherproof cover for your isolator. This simple addition is the best way to shield the switch from driving rain and UV degradation, ensuring it lasts as long as possible.
How to Monitor Your System
You don’t need to climb a ladder to check your system’s basic health:
- Check the Inverter: Look for a green light. If you see a red light or an error code (like “Relay Check” or “Isolation Fault”), your system has shut down for safety.
- Review Wi-Fi Data: Use your monitoring app to compare your current daily production with similar days from last year. A slow decline often goes unnoticed on a power bill but is easily seen in the data.
FAQ
A red light indicates a fault. Do not attempt to fix it yourself, as solar systems carry high-voltage DC current. Switch the system off following the “Shutdown Procedure” (usually located on the inverter) and call a licensed technician for an inspection.
No. High-pressure water can damage the seals around the glass or force moisture into the internal circuitry. A professional clean with the right equipment is the only safe way to restore efficiency.
In South Australia, rooftop isolators are exposed to extreme sun and rain. A cover prevents the plastic housing from cracking and keeps moisture out of the internal electrical contacts, which is a leading cause of solar-related fires.
We recommend a full service every 12 to 24 months, especially for older systems, to ensure all mounting and electrical connections remain compliant with current standards.
