A solar energy collector expansion assembly including means for reducing having axial thermal expansion in the riser tube is described in which each riser tube has a pair of solar collecting panels attached thereto by a removable elongated "C"-shaped connection member. The "C"-shaped connection member is deliberately made from a material having a higher coefficient of thermal expansion than does the material from which the solar collecting panel and the riser tube are formed thereby influencing the dimensional thermal expansion of the riser tube-connection member assembly into a radial rather than axial direction thereby reducing the weakening and failure of the bonds which join the riser tube to adjoining members. Each riser tube-connection member assembly is curved slightly from linear into a cambered shape to further influence the path of thermal expansion of the assembly from a direction other than axial.

A solar water heater absorber with controllable freeze damage is described, the absorber having removable heat absorbing panels attached on opposite sides to each riser, each panel having a flat portion to receive the sun's rays and a folded curved portion to reside next to the horizontal pipe riser. An elongated "C" clamp compressing the curved portion of both panels to the riser provides efficient heat conduction. The risers are arranged in a serpentine fashion with manifolds attaching appropriate adjacent ends and vertical freeze expansion pipes attaching to the manifolds through bridge pipes, one freeze expansion pipe at each end of the risers. At one end of each freeze expansion pipe is a test cap. Water flow through the bridge pipe is restricted by an internal plug with orifice, a reduced diameter bridge pipe, or an opening formed in the manifold or into connected freeze expansion pipes encompassed by the bridge pipe. In the event of a mild freeze, water freezing in the riser will expand into the freeze expansion pipes and escape by rupturing the test cap and thereby reduce damage.
