1. A method implemented in a solar module, the method comprising:
generating, by a photovoltaic panel, an output;
receiving, in a local management unit connected to the photovoltaic panel, the output as input,
the local management unit having a controller and a communication module coupled to the controller to receive communications from a remote unit, the communications configured to cause the solar module to change from a first mode of outputting power to a second mode of being shut down from outputting power;
providing power using a first circuit path from the output of the photovoltaic panel to the controller in the first mode, wherein in the first mode a switch connecting the output of the photovoltaic panel to the controller is open;
providing power using a second circuit path from the output of the photovoltaic panel to the controller in the second mode; and
causing, by the controller in the second mode, the local management unit to shut down outputting power from the solar module.
