In a solar energy collector having a solar window portion and a thermally cyclical solar energy receiver element located therewithin, a support for the receiver element adapted to locate same in spaced relation with respect to the window and to accommodate linear expansion and contraction of the receiver element relative to the window due to thermal cycles thereof, the support comprising; a bearing adapted to engage opposed surfaces of the receiver element and the window including a plurality of roller bearings being selectively located between the opposed surfaces of said window and said receiver for spacing one from the other and being free to rollably carry the receiver element as it expands and contracts during thermal cycles, and a frame member located between said opposed surfaces of said window and said receiver including retainer means for associatively accommodating one each of the roller bearings therein and securing each to a limited path of rotation relative to the window and the receiver element during each thermal cycle.
