The subject of the invention relates to a solar collection surface device with multiple integrated thermal acceleration foci. It consists in the coating of drops of water 3, 4, 5 between two transparent synthetic resin films 1, 2, such that the volume and the shape of these coatings approximate as closely as possible to the section of a converging lens with small focal distance. It is intended greatly to enhance the heating effect by multiple point concentrations of overheating foci and to be applied to any transparent screen affording the possibility of trapping solar heat. <IMAGE>
