Abstract: A photovoltaic solar installation includes solar trackers, respective fixed support structures, and a mobile frame assembled on each support structure. The mobile frame bears a solar panel for rotation in relation to the fixed structure to orient the solar panel to follow the movement of the sun to obtain impingement of sunlight on the solar panels. A connection element attaches to all the mobile frames and to drive means. Control means controls the drive means in order to move the connection element in both directions to make all the mobile frames rotate simultaneously. A circular structure concentric to the axis of rotation of each mobile frame provides a support track for the connection element so that the connection element runs over at least part of a peripheral contour of the circular structures of the mobile frames, being fixed at a point of the peripheral contour of each circular structure.
