PVStop is a fire retardant solution that acts as a liquid blanket to make solar panels safe in the event of a short circuit or an emergency (such as a fire or flood). Solar panels continue to produce potentially lethal amounts of DC voltage.
How Does it Work? 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.
Quick The PVStop spray delivery system allows users to cover solar panels in a matter of seconds. The fire retardant solution blocks light to the PV cells upon contact. The neutralisation process takes less than three seconds; to completely disable the solar panel can take as little as six seconds. Portable PVStop is designed to operate in a similar fashion to a fire extinguisher and comes in a variety of sizes for flexibility and portability. These delivery systems range from small hand-held vessels to large pump & hose extinguishers. PVStop can be sprayed at a safe distance ranging from 5-30m, which allows the coating to be applied either directly from the roof for installation and maintenance or from the ground in an emergency or fire situation.
Sticky The polymer film is designed to stick to solar panels during all weather conditions. Even if the PV modules are wet the coating will stick to the glass panel unlike something like fire fighting foam that has a tendency to slide off smooth surfaces.
Peels Off Once the coating has dried, PVStop can be easily peeled off by hand. The coating does not contain any adhesives and does not damage solar panels in any way. The coating can be peeled off up to 12 months after being applied even when exposed to UV and other weather elements.
Fire retardant solution 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.
Easy to Dispose Once it has served its purpose PVStop can be peeled off the solar panel by hand, condensed into a small ball and disposed of safely in domestic waste.
Reactive Solution Current solutions for reducing solar panel hazards are all preventative which means that that they need to be installed before a disaster or a hazard occurs for them to be effective. PVStop empowers solar panel owners, fire fighters and emergency personnel with a reactive tool that will render solar panels electrically safe when required.
