Recent fire incidents in Pakistan have brought an uncomfortable but necessary topic into public focus: safety. The January 2026 mall fire in Karachi and the hotel fire in Lahore served as stark reminders of how quickly fire hazards can escalate in dense urban environments. While neither incident was linked to solar systems, both have heightened awareness around building safety, electrical risks, and the importance of preventive design.
As rooftop solar adoption accelerates across Pakistan, particularly in commercial buildings, malls, hotels, and industrial facilities, the discussion must extend beyond energy generation and cost savings. Fire safety, especially at the solar module level, deserves equal attention. This is where advanced anti-fire solar technologies, such as the Hi-MO X10, become increasingly relevant.
Shading: A Hidden but Serious Fire Risk
One of the most underestimated causes of photovoltaic (PV) fire risk is partial shading. In real-world installations, shading is often unavoidable. Rooftop equipment, nearby structures, dust accumulation, bird droppings, scale buildup, and uneven cleaning can all obstruct sunlight from portions of a solar module.
In conventional solar modules, shading disrupts current flow. When electricity cannot pass evenly through shaded cells, it concentrates in specific areas, leading to localized overheating, commonly known as hot spots. Over time, these hot spots become one of the leading triggers of PV-related fires, especially in long-term rooftop installations exposed to continuous thermal stress.
Advanced Anti-Shading Design
The Hi-MO X10 addresses this challenge through an advanced anti-shading design that fundamentally improves how modules respond to partial shading. In conventional systems, shading can cause energy losses of up to 35%, significantly increasing heat buildup. By contrast, Hi-MO X10 limits energy loss to approximately 8% under similar conditions.
More notably, when a single cell is shaded, Hi-MO X10 reduces power loss by around 70% compared to standard TOPCon modules. This improved current management allows electricity to flow more smoothly, substantially lowering heat accumulation and reducing the likelihood of hot spot formation.
Soft Breakdown Technology
A key differentiator of the Hi-MO X10 is its innovative soft breakdown technology. Traditional module designs often trap blocked current within shaded areas, intensifying heat concentration. Hi-MO X10, however, enables excess current to bypass shaded zones in a controlled manner.
By preventing excessive heat buildup at the cell level, this proactive approach stops hot spots before they form, marking a critical advancement in module-level fire prevention.
Proven Heat-Reduction Performance
Independent testing confirms that Hi-MO X10 reduces localized cell temperatures by more than 28% compared to regular cells. Lower operating temperatures directly reduce fire risk while also enhancing module longevity and overall system reliability. In high-temperature climates like Pakistan’s, this heat-reduction capability is particularly important for rooftop safety.
Fire Prevention as Asset Protection
Although PV fire incidents are relatively rare, their consequences can be severe, ranging from financial losses and insurance disputes to reputational damage and prolonged operational shutdowns. Hi-MO X10’s anti-fire mechanism effectively acts as a “30-year fire insurance” for rooftop solar systems by integrating safety directly at the module level.
Lessons from Global Incidents
Global PV fire cases reinforce this need for built-in safety, including incidents in Australia, China, the UK, and Europe, as well as the Walmart vs. Tesla (SolarCity) case and the Shanghai Hongmei South Road PV fire in 2025. Each highlights a clear lesson: fire prevention cannot be an afterthought; it must be engineered into the module itself.
A Safer Path Forward
As Pakistan’s solar market continues to grow, recent urban fire incidents should serve as a timely reminder that safety and sustainability must go hand in hand. Technologies like the Hi-MO X10 demonstrate how innovation can directly mitigate real-world risks while delivering reliable clean energy for decades to come.
