Learn how PVSTOP stopped a dangerous solar panel fire at a London school protecting students and facilities.
When a fire broke out on the roof of a London school, what could have become a serious incident was swiftly contained thanks to quick-thinking firefighters and an innovative solar safety product — PVSTOP.
According to the London Fire Brigade, crews were called to reports of smoke coming from solar panels at a South London school. Upon arrival, they discovered a solar panel fire spreading across the array. Because solar panels continue to generate electricity even when disconnected, tackling such fires can be dangerous for firefighters, posing the risk of electrocution.
Firefighters turn to science
To make the area safe, the attending crews used PVSTOP — a specially designed, non-conductive spray-on polymer that isolates and suppresses the electrical output of solar panels. When applied, PVSTOP forms a temporary protective coating that blocks light and immediately stops energy production from the panels, allowing firefighters to work without risk of electric shock.
In this case, the product allowed the London Fire Brigade to extinguish the flames quickly and prevent further damage to the building. The Brigade later described the outcome as an example of “sticky science” saving the day.
The growing challenge of solar panel fires
Solar energy systems are becoming increasingly common on schools, homes, and businesses across the UK and Australia. However, as installations rise, so does the potential for electrical faults and fire hazards. A solar panel fire can spread rapidly if not isolated — and because PV systems continue to produce live voltage when exposed to light, traditional firefighting methods aren’t always effective.
PVSTOP’s role in fire safety
PVSTOP — developed and manufactured in Australia — is the only liquid solution designed specifically to make solar panels electrically safe in an emergency. It can be applied manually, via a hose line, or through portable pressure vessels for rapid deployment.
Once the incident is under control, the polymer can be safely peeled or washed away, leaving the panels intact. The product has been independently tested and approved by international fire authorities and is increasingly being adopted by emergency services and facility managers worldwide.
For organisations looking to enhance their solar safety protocols, PVSTOP offers a simple, effective way to manage the risk of a solar panel fire. More information on how the system works and its applications in both emergency response and preventative maintenance can be found on the PVSTOP Products page or in the FAQ section.
A lesson in prevention
The London school fire serves as a powerful reminder of how science and innovation can protect lives and property. What might have been a costly and dangerous event was contained without injury — thanks to the right tools and informed decision-making.
As the use of solar energy continues to expand globally, so too must awareness of fire safety in photovoltaic systems. PVSTOP’s success in London demonstrates that preparation and technology can work hand-in-hand to prevent disaster — and ensure that clean energy remains both sustainable and safe.
