Abstract

The invention relates to a device for monitoring photovoltaic panels in the event of theft or damage. The aim of the invention is to provide a solution that, without a predetermined action of nominal current, furnishes a signal by a monitoring of direct current voltage in the event of damage or theft. To this end, the invention provides that a window comparator with programmed reference voltage divides the residual voltage of the photovoltaic panels, which is given at twilight or night, into three categories: outside, inside and below and, per panel, a coded signal typical for a panel is sent to a central alarm device, which is located next to the inverter and which has a decoder that sets off a panel-specific alarm in the event the signal indicates below.
