1. A panel having a generally rectangular shape and of plastics material moulded by extrusion and blowing, for collecting solar energy, in which there are formed a conduit (13) arranged in a serpentine manner for the circulation of a liquid to be heated, and two tubular elements (14, 23) adjacent to two opposed edges of the panel and connected to the respective ends of the conduits for the inlet and the outlet of the liquid, one of the tubular elements constituting a header section (14) whose ends are adapted to be capable of being connected in a sealed manner to the header sections of two laterally disposed adjacent identical panels (A), characteized in that the tubular element opposed to the header section (14) constitutes a nozzle (23) which is perpendicular to the header tube in the plane of the panel of and is located in the centre of the edge of the corresponding panel (b) and this edge has, on each side of the central nozzle, means permitting a rapid assembly with the corresponding edge of an identical adjacent panel (A) disposed at the end thereof and oriented at 180 degrees relative to the first panel. |
