The panel includes two V-corrugated sheets secured together with their corrugations in parallel alignment to form parallel channels, and two sidewalls closing the ends of the channels. The sheets are secured together along their edges and between channels. The outer surface of one sheet forms two sets of parallel absorbtive faces which, with the panel inclined, are positionable parallel to the longitudinal axis of solar travel over the panel during each solar day, and perpendicular to the direction of incident solar radiation at summer solstice and winter solstice, respectively. Adjacent channels are connected intermediate their ends at one or more locations by transverse flow passages through which a heat exchange fluid may be transferred in a direction transverse to the lengths of the channels. The heat exchange fluid is introduced into the channel adjacent the upper edge of the panel and flows downward by gravity through the channels in sequence toward the channel adjacent the lower edge of the panel, from which it is discharged.
