Abstract
An evacuatable solar collector, comprising a collector tub, a radiotransparent pane sealingly covering the tub, an absorber arranged below the pane, and support members passing through the absorber and having a limited cross-section whereby, in the evacuated state of the absorber, said support members support the pane in punctiform manner from the inside in places distributed over the surface area thereof, against the action of the external atmospheric pressure, wherein the support members in turn are supported against means engaging with the bottom of the collector tub and which bring about a distribution of the forces exerted by the support members on the tub bottom counteracting marking of the latter.
