Abstract

Solar power generation plants are designed from one or more parallel strings of photovoltaic (PV) modules and feed into a low-voltage system via inverted rectifiers. According to the invention, a switching element (A) is associated with each PV module (1 to 400) at the output end, the switching element (A) being switchable by means of an enable signal (FG) in such a way that the associated PV module is dead when there is no enable signal (FG) while being activated when an enable signal (FG) is supplied.
