Sensor Device for Monitoring the Operation of a PV System, and PV System with Such a Sensor Device
First Claim
1. Sensor device (5) for monitoring the operation of a PV system, said PV system having at least one PV module (1) with a plurality of PV cells (3) laminated on a support plate (2), characterized by a substrate with an electronic circuitry (9) adapted to be mounted on the support plate adjacent to PV cells of the PV module, said circuitry comprising two or more input terminals (7,8) for receiving an output voltage of a series connection of one or more PV cells of a PV module, and a comparator (T1,T2;
- U2,U3) for comparing the output voltage received on the input terminals with a first reference voltage corresponding with a first operation level of the PV module, the comparator controlling a first signalling element (12;
20,21) for signalling the operation of the PV module above said first operation level.

Abstract
A sensor device (5) for monitoring the operation of a PV system is described. Such a PV system has at least, one PV module (1) with a plurality of PV cells (3) laminated on a support plate (2). The sensor device (5) comprises a substrate (6) with an electronic circuitry (9) adapted to be mounted on the support plate adjacent to PV cells of the PV module. The circuitry comprises two or more input terminals (7,8) for receiving an output voltage of a series connection of one or more PV cells of a PV module, and a comparator (T1,T2) for comparing the output voltage received on the input terminals with a first reference voltage corresponding with a first operation level of the PV module. The comparator controls a first signalling element (12) for signalling the operation of the PV module above said first operation level.
