PVSTOP
Solar Panel Block Out

PV Stop Water-Based Polymer agent is a revolutionary, tested and certified technology specifically designed to instantly blocking sunlight and safely shutting down solar panels during an emergency.

Solar panels generate electricity whenever exposed to light and cannot simply be ‘switched off’ in an emergency. This ‘DC Danger Zone’ creates persistent electrical hazards that exist regardless of isolator switches, rapid shutdown systems, or other electrical controls. PVSTOP addresses this fundamental problem by blocking light at source, immediately stopping power generation on contact. Even with partial coverage, it effectively breaks the electrical circuit and renders panels electrically safe.

The system allows first responders and maintenance teams to safely isolate panels in the event of a short circuit, storm damage, or at the first signs of smoke or arcing, long before a situation escalates out of control.

PVSTOP is the only solar safety solution to achieve ISO 14034:2016 Environmental Technology Verification, with independent testing confirming effectiveness. The technology has been operationally validated by major fire services worldwide, including London Fire Brigade (LFB), Fire Department New York (FDNY), and Singapore Civil Defence Force (SCDF).

PVSTOP is non-flammable, fire-retardant, weatherproof, and can be safely used on both wet and dry surfaces. Effective on all types of solar panels, the liquid coating solidifies and peels away easily without damaging solar panels. It can remain in place for up to 12 months. Water-based and non-toxic, it is safe to dispose of with general waste.
