A photoelectric sensor (15) is arranged to receive light (in)directly from the same radiation source as the solar generator (11). The current flowing from the latter to the inverter (14), or a magniture representing the current, is picked-up by a measuring appts. (16). The output signals of The sensor and measuring appts. are coupled to a fault detecting stage (17) which transmits a fault signal, when the sensor output signal (E) exceeds a preset threshold (Eo), and the current (I), measured by the appts. is below a preset threshold (Io). Independent claims are included for detecting a fault in the generator.
