The main factors leading to fires of photovoltaic installations are:
When a fire of a photovoltaic installation, even if its inverter or fire-protective circuit breaker cuts the AC power off, it must be kept in mind that both the installation located on the roof, as well as its wiring connected to the aforementioned devices still remain electrified. As long as photovoltaic modules have access to sunlight they constantly generate DC electricity, with a voltage reaching even a few hundred Volts, so they pose a risk to all the people involved in the fire extinguishing action.
FIRE EXTINGUISHING DEVICE FOR PHOTOVOLTAIC INSTALLATIONS
How does Solarstop® work?
Solarstop® generates stable fire extinguishing foam which effectively blocks access of sunlight to photovoltaic modules, as a result the modules stop generating DC electricity.
SOLARSTOP® enables extinguishing photovoltaic modules and equipment such as wiring, connectors, inverters, etc. remaining under a maximum voltage of 1000V, it is also effective for extinguishing A class fires.
