    摘要： The invention relates to a photovoltaic module (1) having at least one bypass network (2) with a data processing unit (36), which allows for at least an entire module string in conjunction with a string monitoring server a simple and cost-effective detection of faults in the circuit even in PV modules which are non-illuminated at night. The bypass network (2) comprises a parallel circuit of a component (31) limiting the negative voltage in the bypass, an additional power switch (30) and an input of a DC-DC converter (33). Provided that the current flowing through the bypass network (2) is below the trigger current, the bypass network (2) can permanently assume in the active region a first active state, in which the additional power switch (30) is not switched on and in which a significant current flows via the bypass network (2). The DC-DC converter (33) is capable of supplying energy to the data processing unit (36) which is associated with the bypass network (2) and, if necessary, actuates the additional power switch (30), provided that the voltage at the bypass network (2) becomes more negative than a start-up voltage (U
    start ) of the DC-DC converter (33).
