PVStop – Fire Retardant Solution
- Duration: ---
- CPD Points: ---
PVStop is nonconductive and the fire retardant solution allows it to be used in emergency fire situations. An electrical arc at the panel can be difficult to extinguish during daylight. PVStop will disable the panel, stop the arc and extinguish any flames.
The primary function of PVStop is to render panels to be electrically safe while acting as a fire retardant solution. The PV module does not need to be entirely covered for the panel to be deactivated. Spraying a line down the middle of the panel, for example, and covering only as much as 25% is enough to interrupt solar power production. However, covering the entire panel will continue to reduce DC voltage to zero.
