<p>The solar collector system has a collector (12) including a roll-bond absorber (13) with an absorber panel (14) in which channels (15) for the circulation of a heat-exchange medium are formed. The collector has input (16) and return (18) connections, and a return line leading to it. A main tube of cross section greater than that of the channels is built into the roll-bond absorber.</p> |
