DC electricity is significantly more dangerous than AC electricity for a number of reasons–high voltage DC power can be lethal, and is prone to ‘ arcing‘, in which electricity literally leaps through the air when there is a fault in circuitry. The cabling that runs between the inverter and the solar panel array carries DC electricity. In most solar PV systems, DC electricity is converted to AC electricity via a centralised inverter, which is usually located some distance from the panels themselves. The electricity produced by solar panels is DC (direct current) electricity, which must be converted into AC (alternating current) electricity in order to be used by most appliances and in order to be exported to the electricity grid. The Issue: Absence of panel isolation mechanisms in solar PV systems SafetyinSolar’s Solar Panel Isolation System adds an extra level of protection, especially for homes located in regions that are prone to bush-fires or flooding, by enabling an entire solar panel array to be essentially ‘switched off’ from a centralised location and rendered harmless. As with any industry, there are certain minimum standards that a solar system and its comprising components must meet in order to be installed to be considered safe.
