System monitoring

WithHeinrich Haeberlin

Monitoring a PV system permits examination of its behaviour under real operating conditions, which may be quite different from the assumptions and simulations made during design. Monitoring clearly shows if the PV system is operating according to the design goals, if it is over- or undersized and if there are potential problems that do not yet affect the operation, but may cause problems in the future and therefore demand preventative countermeasures. Monitored data provides designers with valuable information on how to improve future PV systems. It is also useful when assessing the potential and reliability of PV technology for a given application at a certain location.
