As sensing technologies continue to improve, Paceco Corp. and ASU see an opportunity to gather high-quality granular data from photovoltaic (PV) arrays, with the goal of improving array efficiency and availability. Students of the SenSIP center have developed sophisticated algorithms for automated fault detection in PV arrays using information from such a monitoring system. A procedure has also been developed for dynamic optimization of a PV array’s electrical topology in order to mitigate the effects of faults and maximize power output under non-fault conditions.
