The structure disclosed includes an air supported transparent membrane which encloses a solar collector unit. The solar unit includes a solar collector element and two angled walls that support and position the element. The solar collector element receives and absorbs solar radiation and provides heat to a circulating fluid. The support walls extend forwardly and outwardly from the collector element and have reflecting facing surfaces to increase the amount of radiation falling on the element. The walls extend rearwardly of the element to define a chamber in which small rocks are stored to provide heat storage. The transparent membrane creates a greenhouse effect within the chamber defined by the membrane, increasing the operating temperature and thus the conversion efficiency of the solar collector element. Furthermore, the air supported membrane protects the solar collector unit from wind loading. Thus the unit can be lighter than otherwise might be the case and can be pivoted to have an optimum attitude as a function of the time of year. In addition, protection of the solar collector element from wind and rain means that a thin transparent plastic glazing can be and is used in the element.
