NOVELTY - Floating photovoltaic system (1) comprises: a floating structure (2) with a series of floating modular blocks (3) movably connected to form a basically flat floating grid with a float height (4), a strengthening structure (5) with a series of strengthening beams (6), a supporting structure (8) including one or more rigid supporting frames (9) movably connected to these strengthening beams (6), and one or more photovoltaic panels (7) fixed on these supporting frames (9).    USE - The floating photovoltaic system is useful for transforming solar energy into electrical energy.    ADVANTAGE - The floating photovoltaic system can be installed in water and more specifically in internal waters, e.g. lakes, ponds, mountain lakes, plains or lagoons. The system has characteristics which facilitate changes in its shape and area and to fit harmoniously in the landscape of the installation place.    DETAILED DESCRIPTION - Floating photovoltaic system (1) comprises: a floating structure (2) with a series of floating modular blocks (3) movably connected to form a basically flat floating grid with a float height (4), a strengthening structure (5) with a series of strengthening beams (6), in which each one of these strengthening beams (6) is movably connected to at least two floating blocks (3), a supporting structure (8) including one or more rigid supporting frames (9) movably connected to these strengthening beams (6), one or more photovoltaic panels (7) fixed on these supporting frames (9), in which the strengthening structure (5) is parallel to the floating grid structure (3) level (P) and is arranged within the float height (4).
