ABSTRACT:
A solar collector is disclosed that enables the installation of the collector parallel to the surface plane or angle of any structure, including vertical walls and flat roofs, without affecting generating efficiency. The collector is efficient for both energy absorption and transfer to the transport fluid. The collector removes architectural constraints and is suitable for building structure applications not heretofore possible. The collector comprises an array of integral fin/tube extrusions all of which are aligned in the East-West direction. Mechanical linkage rotates the extrusions in unison, with a sun tracking device, to the solar altitude angle. The extrusions, mechanical linkage, and sun tracking device are contained within an insulated housing enclosure. The integral fluid channels likewise extend in an East-West direction, are spaced apart in the North-South direction and are directed to supply and return manifold piping extending in the North-South direction with inlet and outlet connections. The extrusions have a black anodized selective coating for high absorptance and low emittance. The housing enclosure has a glazing cover.
