Do Not Get Burnt By Solar

Solar Safety: How Fires Happen. Protect Your Investment

As temperatures rise across Australia, rooftop solar systems face extreme conditions that can lead to serious hazards if left unchecked. Regular solar maintenance and inspections aren’t just about efficiency, they’re about safety and protecting your home from fire risks.

Why Warmer Weather Puts Your Solar System at Risk

• Rooftop temperatures can exceed 60°C, placing enormous strain on panels, wiring, and isolators.
• Electrical components exposed to heat and debris can melt insulation, creating a fire hazard.
• Older systems without modern monitoring often go unnoticed until a major fault occurs.

Common Solar Hazards

1. Debris Build-Up and Spot Fires

Gum leaves, dust, and nesting materials can accumulate under panels. Real example: A recent inspection in Morphettville uncovered a tiny spot fire caused by leaf build-up, damaging panels and wiring. Prevention:

• Schedule professional cleaning and inspections before summer.
• Keep roof areas clear of vegetation.

2. Heat Stress on Electrical Components

• Panels and isolators can reach 70°C or more in peak summer.
• Melted cabling or cracked insulation increases the risk of electrical arcing and fire. Tip: Ensure your system complies with AS/NZS 5033 standards and has proper heat-resistant cabling.

3. Poor Original Installations

• Faulty wiring and loose connections are leading causes of solar fires.
• DC isolators, especially older rooftop models, are prone to water ingress and corrosion, creating hot joints that ignite under load. Action:
• Book a licensed solar electrician for a compliance check.
• Replace outdated isolators with safer alternatives.

Benefits of Regular Solar Health Checks

Regular solar health checks offer multiple benefits. They help maximize energy output, ensuring your system runs efficiently and keeps your electricity bills low. Routine inspections also prevent costly repairs by identifying faults early before they escalate into major issues. Beyond performance, these checks are essential for electrical safety and maintaining insurance compliance, giving you peace of mind.

Finally, consistent maintenance extends the lifespan of your solar system, protecting your investment for years to come.

Quick Solar Safety Checklist

1. Clear debris from panels and roof areas.
2. Inspect isolators and wiring for heat damage or corrosion.
3. Test inverter performance and monitor error logs.
4. Schedule a professional solar health check before peak summer.

Don’t Get Burnt by Solar This Summer

Whether you’re buying a home or maintaining your own, check the state of the solar system. A simple inspection can prevent fires, protect your investment, and keep your energy bills low.
