A space-saving lengthwise and widthwise movable panel system capable of being fully opened belongs to the field of smart building technology and includes a lengthwise panel moving compartment, a panel storage space and a panel control module. The movable panel system can be used as a door and/or window system. All of the panels of the system can be entirely stored in the panel storage space and when storing all of the panels entirely in the panel storage space, the panel system is fully open to allow full lengthwise access to a space. The panel storage space may be located in a wall or outside the room to hide the stacked panels. By controlling the operation of the moving system, the panels are effectively connected to one another in an aligned manner and can move automatically, so the space-saving movable panel system is convenient to use, and space-saving.
