Roof-mounted solar panel safety hazards must not be overlooked!

In early July, a sudden fire at the HalfMoon Industrial Park in Wilton sparked widespread concern. Upon receiving the alarm, the fire department swiftly responded to the scene, where they found a row of solar panels on the roof engulfed in flames, with thick black smoke billowing into the air. This caused anxiety among employees at nearby factories and residents in the surrounding area. Although the fire was brought under control within 45 minutes, the solar panels and portions of the roof sustained damage.

Fire Chief Kevin Himmerick stated after the incident: ‘The fire originated from the solar panel area, and the cause of the fire remains unclear.’ He noted that since the solar panels continued to generate electricity, cutting off the power supply at the site required assistance from the factory’s technical staff, resulting in some delay in response. Fortunately, the fire did not spread to the interior of the factory; otherwise, the consequences would have been unimaginable.

This incident once again highlights the safety hazards associated with rooftop photovoltaic systems. As the installed capacity of photovoltaic systems grows rapidly, safety issues are becoming increasingly evident: electrical faults, component ageing, inverter overheating, lack of isolation control in the system, and improper coordination between energy storage systems and photovoltaic systems can all become ‘hidden dangers.’

Against this backdrop, an increasing number of companies are beginning to prioritise the coordinated safety of photovoltaic systems and energy storage systems. Introducing professional energy storage solutions not only improves energy efficiency but also serves as a ‘safety valve’ during system operation, preventing accidents from occurring or escalating.

Huijue Group’s integrated residential and commercial energy storage solutions provide robust safeguards for the safe operation of photovoltaic systems. Huijue’s energy storage products utilise high-safety lithium iron phosphate battery cells, featuring multiple electrical protection designs, including automatic protection mechanisms for overvoltage, overcurrent, and overtemperature, to prevent system overheating or short circuits from causing safety incidents. Additionally, its Battery Management System (BMS) and Energy Management System (EMS) work in tandem to significantly enhance the overall safety and stability of photovoltaic systems.

Especially in rooftop photovoltaic applications, Huijue’s energy storage system offers advantages such as compact size, strong heat dissipation, IP54 protection rating, and robust wind and corrosion resistance, making it highly adaptable. Whether in high-temperature summers or thunderstorm weather, the equipment can operate stably, effectively mitigating electrical risks caused by extreme environments. Additionally, the Huijue energy storage system supports DC/AC dual-coupling solutions, enabling flexible integration with photovoltaic systems while also being applicable for power peak shaving, emergency backup power, and other scenarios, thereby enhancing overall economic efficiency.

In terms of intelligent control, Huijue energy storage equipment supports remote operation and maintenance and real-time data monitoring. In the event of an anomaly, it can immediately trigger an alarm or automatically shut down the power supply, ensuring dual safety for both the system and the building. Compared to traditional distributed photovoltaic systems, Hui Jue’s solution represents a leap from ‘power generation equipment’ to an ‘intelligent energy safety system.’

In the future, Huijue Group will continue to focus on the research and development of safe, efficient, and intelligent energy storage solutions, actively participating in the safety optimisation of various photovoltaic projects, and using technology to safeguard the development of green energy. For rooftop photovoltaic projects on industrial buildings, parks, and public buildings, only by prioritising the safety protection of energy storage systems can we truly ensure that green energy is ‘affordable,’ ‘effective,’ and ‘safer.’
