A solar energy collecting assembly consisting of a rectangular supporting frame with a plurality of vane structures mounted in parallel relationship therein. Each vane structure consists of a generally Z-shaped bar member of extruded aluminum with an integral conduit at the corner between the lower flange and the web of the bar member. The conduit has extended end portions pivotally engaged through the front and rear supporting frame elements and these end portions are clampingly communicatively connected to respective inlet and outlet liquid manifolds located outwardly adjacent the front and rear frame elements. Each vane structure has a top flange provided with a blackened surface acting as a radiation absorber which generates heat, this heat being conducted to the associated conduit via the adjacent web portion of the bar member. The lower flange has an array of photovoltaic cells mounted thereon which can receive solar radiation either directly or via a plane mirror surface provided on the adjacent web portion of the vane structure. The coupling means connecting the conduit end portions to the manifolds includes coupling sleeves with surrounding clamps having tightening screws. The screws are employed for locking the vane structures in pivotally adjusted positions relative to the supporting frame, so that the vane structures can be set for optimum orientation. Each vane structure includes a block of heat-insulating material surrounding its conduit and covering the bottom surfaces of its web and flanges, to minimize heat loss.

In a solar energy collection system, a supporting frame, at least one vane structure transversely mounted in said supporting frame, said vane structure comprising a generally Z-shaped bar member of heat-conducting material having oppositely extending top and bottom longitudinal flanges and a longitudinal web portion connecting said flanges, said bar member being formed with a longitudinal tubular conduit having extended opposite end portions supportingly engaged with said frame, one of said flanges having a darkened top surface, whereby to absorb solar radiant energy to convert it into heat which is conducted to said conduit, and photovoltaic means mounted on the top surface of the other flange in a position to receive solar radiation and thereby generate electrical current.
