1. A method, comprising:
- communicating, via a central controller, with a plurality of local management units (LMUs), each of the LMUs coupled to control a respective solar module;
receiving, via the central controller, a shut-down signal from a user device selected from the group consisting of a hand-held device, a computer, and a wireless switch unit; and
in response to receiving the shut-down signal, shutting down operation of the respective solar module for each of the LMUs.

14. A local management unit, comprising:
-
memory storing software instructions; and a controller coupled to the memory, the controller configured via the software instructions to execute a method comprising; controlling, under supervision by a central controller, a first solar module of a plurality of solar modules, the central controller coupled to supervise a plurality of local management units, wherein the plurality of local management units are coupled by a power bus; and receiving a shut-down command from the central controller to shut down operation of the first solar module, wherein the central controller sends the shut-down command in response to receiving a shut-down signal from a user device selected from the group consisting of a hand-held device, a computer, and a wireless switch unit. - View Dependent Claims (15, 16, 17, 18)

19. A non-transitory computer-readable storage medium for tangibly storing thereon computer readable instructions, the instructions causing a data processing system to perform a method, the method comprising:
-
receiving, via a local management unit, communications from a central controller; controlling, via the local management unit, a solar module; determining whether the communications include a shut-down command; and in response to receiving the shut-down command, shutting down operation of the solar module, wherein the central controller sends the shut-down command in response to receiving a shut-down signal from a user device selected from the group consisting of a hand-held device, a computer, and a wireless switch unit. - View Dependent Claims (20, 21)
