Abstract:
1. A solar energy system, comprising: a plurality of photovoltaic panels; a plurality of local management units, each respective local management unit of the plurality of local management units connected to a respective photovoltaic panel of the plurality of photovoltaic panels and configured to receive power from the respective photovoltaic panel, wherein when the respective local management unit is turned on, the respective local management unit provides power output based on the power received from the respective photovoltaic panel, and wherein when the respective local management unit is turned off, the respective local management unit disconnects the respective photovoltaic panel from the solar energy system; one or more arc detectors configured to detect an arc in the solar energy system; and a system management unit coupled with the one or more arc detectors and configured to be in communication with the plurality of local management units; wherein if the one or more arc detectors detect the arc, the system management unit is configured to identify, via communicating with the plurality of local management units to turn on and off the plurality of local management units, a location of the arc in the solar energy system.
