Abstract
A shut-down apparatus for a string of photovoltaic panels electrically connected in series wherein it comprises a plurality of control modules comprising: an initial control module operatively associated to a corresponding photovoltaic panel; one or more intermediate control modules, each operatively associated to a corresponding photovoltaic panel; a final control module operatively associated to a corresponding photovoltaic panel. Each control module is adapted to cause the shut-down of a corresponding photovoltaic panel in response to a received input shut-down signal, said control modules sequentially receiving said input shut-down signals at subsequent shut-down instants, each pair of subsequent shut-down instants being separated by a corresponding time delay.
