A solar energy collector comprises two substantially parallel walls 1, 2, particularly of plastics material, connected edgewise and between which are formed at least one inlet channel 14 and one outlet channel 15, and a plurality of connection channels 16 between the inlet and outlet channels for a heat exchange fluid. At least one wall has on its side facing the other wall a plurality of projections 7, 8 and/or ribs 3-6, 17, 18 for the formation of the connection channels 16 and the other wall is connected at least regionally with the elevated surfaces of the projections 7, 8 and/or ribs 3-6, 17, 18. <IMAGE> |
