The Incident

The LFB received the first of 14 calls reporting the fire at around 12:20 pm. The solar panel was located on the roof of the building, necessitating the use of one of the brigade’s 32m ladders. Firefighters quickly applied PVStop to the solar panel, a product stored in an extinguisher and sprayed onto the panels during such emergencies. PVStop works by blocking sunlight from reaching the solar panels, effectively stopping the conversion of light into electricity. This allows firefighters to safely address the fire without the risk of electric shock or further electrical fires.

Thanks to the swift application of PVStop, the fire was under control by around 1:10 pm, with no reported injuries. Firefighters from Lewisham, Greenwich, Lee Green, and surrounding stations attended the scene, showcasing a coordinated and effective response.

The Importance of PVStop in Firefighting

PVStop has proven to be an invaluable tool for fire brigades dealing with solar panel fires. Its ability to safely and effectively de-energize solar panels ensures that firefighters can operate without the added danger of live electricity. In this incident, PVStop allowed the LFB to quickly and safely extinguish the fire, protecting both lives and property.

Public Awareness and Safety

The incident was captured by a nearby resident and posted on TikTok, highlighting the community’s role in early detection and response. Although the footage did not capture the moment PVStop was applied, it serves as a testament to the product’s effectiveness and the professionalism of the London Fire Brigade.

The quick response and use of PVStop not only controlled the fire but also ensured that the building remained safe for residents until the solar panel system could be properly inspected and repaired. PVStop can stay on the PV modules for up to a year, providing ongoing protection. When it is time to recommission the system, the polymer coating can simply be peeled off and disposed of as normal waste.

Conclusion

The recent solar panel fire in Lewisham underscores the critical importance of having effective tools like PVStop available for first responders. This incident is a perfect example of how early detection, combined with professional and well-equipped fire services, can prevent potential disasters.

By embracing innovative solutions like PVStop, fire brigades can enhance their ability to manage the growing risks associated with solar panel installations, ensuring safer communities and better protection for all.

As a life safety solution provider, our mission is to equip emergency responders, particularly firefighters, with the tools and knowledge to manage the unique risks posed by solar PV systems. The primary hazard in such systems is electrical, which, if not promptly mitigated, can escalate into fire incidents.

The challenge is multi-faceted: there is a lack of enforceable regulation on solar PV installations, these systems are typically located out of sight on rooftops, and there is a diverse array of solar systems currently installed, in progress, or planned for the future.

The Need for Accurate Data Capture

PVStop International extensive conversations with UK Fire Brigades and global Fire Services have led us to believe that the data captured on solar PV incidents is significantly underreported. Publicly available data reports, such as the 2017 BRE Global report, acknowledge that the total number and nature of incidents are not being adequately captured by current systems.

PVStop International propose that the National Incident Reporting System and the National Fire Investigation Reporting System harmonize data capture for solar PV electrical and fire incidents. This would not only improve the quality and consistency of data but also enhance the operational protocols used by firefighters to manage these incidents.

The Proposed Solution

PVStop proposed a simple, effective method for incident reporting, focusing on solar PV systems. This involves two main steps:

1. Incident Reporting System:
   • Confirm the option to select solar PV systems.
   • Introduce two primary options:
     • PVIR1: Solar PV as Direct Ignition Source.
     • PVIR2: Solar PV Indirectly Involved (Other ignition sources).
   • These options address the direct and indirect risks posed by solar PV systems, ensuring firefighters can report incidents without needing extensive technical knowledge.
2. Fire Investigation Reporting:
   • Under PVIR1, we propose seven specific categories to capture the source of ignition:
     • PVFIS01: Ignition caused by PV module.
     • PVFIS02: Ignition caused by isolator.
     • PVFIS03: Ignition caused by inverter.
     • PVFIS04: Ignition caused by combiner box and fuse.
     • PVFIS05: Ignition caused by cable.
     • PVFIS06: Ignition caused by connector.
     • PVFIS07: Ignition caused by Solar PV system (Inconclusive Source).

These categories will significantly improve the quality and consistency of data reporting on solar PV incidents. The solution ensures that firefighters can de-energize solar systems safely and effectively by blocking light to the panels, using our PVStop product. Additionally, we provide solar safety training to firefighters and those involved in the installation, operation, and maintenance of solar PV systems.

Call to Action

To further enhance the safety of emergency responders and the general public, we urge the relevant authorities to adopt our proposed incident reporting method. Accurate data capture and analysis will provide a clearer picture of the risks associated with solar PV systems, enabling the development of robust operational protocols and safety measures.

By implementing this standardized reporting system, we can ensure that the growing risks posed by solar installations are managed effectively, thereby protecting both firefighters and the communities they serve.

As solar PV installations continue to increase, it is imperative that we have accurate data capture and reporting mechanisms in place. These proposed method offers a straightforward and effective solution to improve the safety and response strategies of firefighters dealing with solar PV incidents. We look forward to collaborating with fire services and regulatory bodies to bring this initiative to fruition, ultimately enhancing safety and operational efficiency across the board.

In the realm of building safety, particularly concerning fire protection, adhering to established regulations is paramount.
