Health monitoring of large amounts of photovoltaic systems

We describe a system for monitoring and analyzing the health of large amounts of technical systems. The focus in this multi-system setting is on systems with a lack of sensors. That is, we only have limited information of the systems. The basic idea of our application is the concept of an alarm list. Based on algorithms for fault detection and the classification of detected faults, alarms are generated and prioritized. Our work is tailored...
