A solar collecting apparatus for collecting solar energy in a heat transfer fluid includes an upper header member, a lower header member, and a plurality of collector tubes, each collector tube connected at an upper end thereof to the upper header member and connected at a lower end thereof to the lower header member. The collector tubes are arranged such that axes of the collector tubes form an array wherein no three adjacent axes are on the same plane, typically in a cylindrical or like array.
