Therefore, it was felt the need to put right a structure which could allow reducing the maintenance and production costs, in particular in terms of maintenance and assembly times, with a simplification of the construction.
  • the modular floating structure for photovoltaic installations is characterized in that it comprises raft-like floating elements which can be inter-connected in such a way to obtain uniform floating surfaces able to hold the supporting structures of the photovoltaic panels and to form a continuous surface for the passage of the maintenance staff.

  • Tubular elements are an integral part of the structure of the rafts, and they are placed on both sides of the floating means.

  • Flanged or tubular seats 102 placed on at least one side of the floating raft-like element 1 present holes 102a for the insertion of at least one supporting bar 3 for the traditional solar panel 5, not described in detail.
  • said holes 102a show an internal diameter slightly larger than the external one of the bars, to determine a friction pairing such that any unwanted vertically directed of the bar itself is avoided.
  • the bar can be moved vertically inside the holes to set the height of one side of the solar panel 5, being blocking means provided for in such a case.
  • a second bar 4 is provided for, which can be drown in the raft-like element 1 or inserted in an appropriate seat provided for on such element 1, to form the second supporting element of the solar panel 5, which can be both fixed and mobile.
  • bars 3 and 4 are preferably made of HDPE, and they are hollow, this way allowing electric wires to be passed inside, and they are conveniently threaded at both ends to be connected at the lower extremity with said floating raft-like elements 1 and with said blocking means, and to be connected at their upper extremity with coupling joint means 6 for the tilting of same panels.
  • connection between the solar panel 5 and their relative supporting bars 3 and 4 is obtained by means of at least one coupling joint 6 interposed between the bars themselves and at least one supporting structure 7 fixed to the solar panel 5.
