Solar Panel Fire Extinguishers – PVSTOP Solar PV Block Out Spray (4.5L & 9L) – Instant DC Isolation
At HSE Store we supply the UK’s leading solar panel fire extinguishers – the revolutionary PVSTOP Solar Panel Block Out system. As solar PV installations continue to grow rapidly across homes, commercial rooftops and solar farms, the unique “DC Danger Zone” hazard has become a critical safety issue: solar panels keep generating high-voltage DC electricity even during fires, floods, storms or maintenance. PVSTOP is the only proven solution that instantly “switches off” solar panels by creating a light-blocking polymer film, making them electrically safe within seconds.
Our dedicated solar panel range includes:
- PVSTOP Solar Panel Block Out – 4.5 Litre – ideal for residential systems, smaller commercial arrays and rapid response on rooftops.
- PVSTOP Solar Panel Block Out – 9 Litre – perfect for larger commercial installations, solar farms and extended coverage requirements.
PVSTOP is a patented, water-based, non-flammable, non-conductive, anti-arcing and fire-retardant formula that dries quickly into a peelable, protective film. It is environmentally friendly, leaves no permanent damage to panels and provides up to 12 months of weather-resistant protection if left in place. British manufactured and globally accredited, it is the essential safety tool for fire & rescue services, solar installers, facilities managers and property owners.
Why solar professionals and safety teams choose PVSTOP:
- Instantly isolates DC power – the only solution that truly “switches off” live solar panels
- Non-conductive and anti-arcing – eliminates electrocution risk in emergencies
- Fast coverage with long spray duration (up to 70 seconds on 9L model)
