  • a water line 151 can be provided between two rows of photovoltaic panels of two successive structures, which is devoid of covers, and which thus allows part of the light to pass under water to reduce the impact of the center on underwater life.
  • a grating 152 can also be provided between two adjacent structures in the direction of the rows of photovoltaic panels, to allow easy access to the panels for maintenance, upkeep or repair operations.
  • the grating can be adapted to rigidly connect the structures 10 together while leaving an interval of the width of the grating, for the movement of operators.
  • the use of a tarpaulin made of catamaran trampoline fabric can however replace these gratings.
