Abstract: An absorber for a solar heating panel, designed to contain heat-bearing liquid, and including first and second metal plates fixed to each other in a sealed manner, a matrix of geometrical shapes applied in relief on each of the first and second plates, with the matrices being staggered so as to trace a path for the circulation of heat-bearing liquid in the absorber, and first and second end-pieces placed at the ends of either of the plates so as to provide for circulation of heat-bearing liquid in the absorber, wherein the metal plates are copper plates, and in that non-traversing mechanical connecting means are used to attach the two copper plates together.
