Theft of solar modules is not uncommon these days. Reports of burglaries in solar parks and photovoltaic plants indicate that organized gangs are at work here. But high replacement costs and the failure of an entire plant because of minor defects or faults are a major problem for the operator. Critical mobile phone and power grid connections of the isolated solar parks are an additional risk factor. Alarm.direct, a service provider for security solutions, has specialized in solar park security in various European countries, Canada and the Dominican Republic, and has developed comprehensive concepts to protect against the theft of plant components such as copper cables, solar panels, inverters, against vandalism and the consequent operational failures.
