Abstract: A web control system for solar tracking includes one or more trackers, a communication port management unit, a status processing unit, a tracker control unit, a back tracking unit, a web server unit, and the memory unit. The trackers operate in compliance with driving commands and change the position of a solar cell panel in response to the tracking of the location of a sun. The communication port management unit is responsible for data transmission and reception. The status processing unit scans the status of the trackers. The tracker control unit directly controls the trackers. The back tracking unit analyzes the status information, and controls the tracker control unit. The local GUI interface unit displays a local or remote user screen. The web server unit provides the GUI data to a user. The memory unit stores the information.
