TECHNOLOGY FOCUS - ELECTRONICS - Preferred Tracking Photovoltaic Plant: The plant comprises second movement means (15) mounted on the support frame (11), operatively associated with each photovoltaic panel (12), and able to determine a second movement of the photovoltaic panel (12) with respect to a second axis of movement (''Z''), different from the first axis of movement (''A''). The plant comprises at least two reflective elements (21) for each photovoltaic panel (12), of which at least one is linearly mobile by sliding, where the two reflective elements (21) are disposed opposite each other with respect to the first axis of movement (''A''). The plant also comprises at least a command and control unit (26) connected to the first movement means (13, 113), to the other movement means (22, 23, 25), and/or to the second movement means (15), in order to coordinate the reciprocal actuation. The plant also comprises sensor means (27) electronically connected to the command and control unit (26) and able to condition, depending on determinate parameters and detected data, the actuation of the first movement means (13,113), of the other movement means (22, 23, 25) and/or of the second movement means (15), where the sensor means (27) comprise one or more position, meteorological and/or temperature sensors. The first movement means (13) comprise at least a screw type actuator (16) able to move a movement bar (17) constrained to each photovoltaic panel (12) of the same line or battery. The first movement means (113) comprise at least an actuator (116) able to move respective movement cables (117) connected by means of relative movement levers (119) to each photovoltaic panel (12) of the same line or battery. The second movement means (15) comprise at least a pantograph actuator (20). The angle of incidence between the photovoltaic panel (12) and the relative reflective element or elements (21) is fixed and predetermined. Each photovoltaic panel (12) comprises cleaning means (30) provided in correspondence with the sides with respect to which the reflective elements (21) slide linearly and disposed in contact with the reflective surface of the relative reflective element (21), so as to carry out the cleaning of the reflective surface during the linear sliding movement of the reflective element (21) with respect to the photovoltaic panel (12) between the first operating position and the second inactive position. The plant comprises a single frame (31) on which the photovoltaic panels (12) are mounted, which frame (31) is moved at least by the first movement means (13) so as to determine the simultaneous movement of all the photovoltaic panels (12) with respect to the first axis of movement (''A''). Preferred Method: The movement method for a tracking photovoltaic plant comprises a second movement of the photovoltaic panel (12) with respect to a second axis of movement (''Z''), different from the first axis of movement (''A''), by means of second movement means (15) mounted on the support frame (11) and operatively associated with each photovoltaic panel (12).
