With solar power now firmly established as a mainstream energy choice for South Africans, ASP Fire, a leading fire risk consulting company, has cautioned that poorly designed or badly installed systems are increasingly giving rise to dangerous fire incidents.

CEO Michael van Niekerk notes that the rapid expansion of the solar market, coupled with the influx of new suppliers and installers, has heightened the risk of unsafe practices. A major insurance company recently reported a notable increase in property damage linked to defective workmanship and substandard solar equipment.

“Lithium battery fires are among the most challenging to contain because they are self-sustaining,” says van Niekerk. “Once a battery goes into thermal runaway, the fire can escalate rapidly and becomes very difficult to extinguish.” He stresses that only systems signed off by qualified engineers and equipped with robust battery management systems can provide adequate protection.

While solar energy continues to offer households and businesses greater independence and long-term savings, van Niekerk warns that cutting corners on installation or relying on low-quality components can have catastrophic consequences. Issues such as arc faults in DC circuits, inadequate surge protection, or faulty wiring are among the leading causes of solar-related fires.

ASP Fire highlights the importance of preventative measures such as choosing certified installers, ensuring that a Certificate of Compliance is issued, and insisting on quality components from reputable suppliers. Regular maintenance and inspections also play a vital role in safeguarding system integrity, while monitoring tools can help detect anomalies before they develop into major hazards.

“Solar energy is here to stay, but safety cannot be an afterthought,” concludes van Niekerk. “By prioritising quality, compliance, and proper oversight, South Africans can harness renewable power with confidence while reducing the risk of fire.”

ASP Fire continues to provide specialised risk assessments, consulting services, and fire safety training, supporting both homeowners and businesses in making solar power a safe and sustainable investment.
