NOVELTY - Tracking photovoltaic plant (10) comprises a support frame (11), photovoltaic panels (12), at least first movement means (13, 113), other movement means (22, 23, 25), and reflective element (21).    USE - The tracking photovoltaic plant is used for solar tracking photovoltaic technology (claimed).    ADVANTAGE - The present invention provides a tracking photovoltaic plant which, keeping the limited bulk and the versatile installation of plants with a light structure, has the greater photovoltaic efficiency of plants with a heavy structure.    DETAILED DESCRIPTION - Tracking photovoltaic plant (10) comprises a support frame (11), photovoltaic panels (12) mounted in lines or batteries, on the support frame (11), and at least first movement means (13, 113) mounted on the support frame (11), operatively associated with the photovoltaic panels (12), and able to determine a first movement of the photovoltaic panels (12) with respect to a first axis of movement (''A''), characterized in that at least one of the photovoltaic panels (12) comprises, in correspondence with at least one of its sides, at least a reflective element (21) mounted sliding with respect to the photovoltaic panel (12) and able to convey other solar rays toward the photovoltaic panel (12), and other movement means (22, 23, 25) operatively associated with the reflective element (21), in order to determine the linear sliding movement of the reflective element (21) with respect to the photovoltaic panel (12) between a first operating position, in which it protrudes laterally from the bulk of the photovoltaic panel (12), and a second inactive position, translated by sliding with respect to the first operating position, in which it is included in the bulk of the photovoltaic panel (12). An INDEPENDENT CLAIM is a movement method for a tracking photovoltaic plant comprising a support frame (11) which extends mainly horizontally, photovoltaic panels (12) mounted in lines or batteries on the support frame (11), the method comprising at least a first movement of the photovoltaic panel (12) with respect to a first axis of movement (''A''), by means of first movement means (13, 113) mounted on the support frame (11) and operatively associated with each photovoltaic panel (12), where at least during the first movement it provides a movement of at least one reflective element (21) provided in correspondence with at least one side of at least one of the photovoltaic panels (12), between a first operating position, in which it protrudes laterally from the bulk of the photovoltaic panel (12), in order to convey other solar rays toward the photovoltaic panel (12), and a second inactive position, in which it is included in the bulk of the photovoltaic panel (12), by means of third movement means (22, 23, 25) operatively associated with the reflective element (21).
