Abstract: Floating element (1) for realizing floating structures for supporting photovoltaic panels and method for producing said floating element (1). The floating element (1) comprises: a first element (2) which can be obtained by injection moulding, which configures a first coupling portion (3); a second element (4) which can be obtained by injection moulding, which configures a second coupling portion (5). The first element (2) and the second element (4) are mutually configured so that the first coupling portion (3) and the second coupling portion (5) can be seal-coupled with respect to each other so that they define a sealed chamber, when coupled.
