Evacuated solar panel (1) comprises a frame (2) carrying spacers (3,4) crossing one another and one or two transparent walls (10, 10a) connected to said frame (2) and defining with said frame (2) an evacuated closed chamber (11). The chamber (11) contains the longitudinal and transverse spacers (3,4) and an absorber (14) comprising a plurality of absorbing panels (14a, 14b) each connected to a cooling pipe (15) welded to the frame (2) at both extremities. The longitudinal spacers (3) are in contact with the transparent wall (10) to support it against the ambient pressure, while the transverse spacers (4) support the longitudinal sides of the frame (2) against the ambient pressure and are not in contact with the transparent wall (10), so allowing the absorbers (14a, 14b) to cover the whole length of the panel (1) without interruptions.
