The solar collector comprises a plurality of chambers connected to one another through interconnecting ducts, said chambers being defined, on the upper side of the collector, that is the side facing to the sun-by transparent outwardly- convex surfaces, hile the pipes of the piping system enclosed within the housing extend through the chambers and the interconnecting ducts. On the lower side of the collector, the chambers and interconnecting ducts are defined by inwardly-reflecting surfaces which have an outwardly-convex configuration.
