energy absorber 10 may be connected in a parallel arrangement such that individual inlet passageways 31 are connected to a common inlet manifold 37 and their individual outlet passageways are connected to a common outlet manifold 46 alternatively fig4 several solar energy absorbers 10 may be connected in a series arrangement such that the outlet passageway of one collector is connected to the inlet passageway of another collector to form a joint passageway 49 such arrangements as shown in fig3 and fig4 may be ued depending on the intended use of this invention other similar arrangements will be obvious to those skilled in the art fig5 illustrates the employment of the invention to heat the interior of a structure or building several solar energy collectors 10 are mounted on the roof of a structure 55 and are positioned so as to intercept the rays of the sun 58 it is not necessary for the practice of the invention that the collectors be roof mounted they may be mounted in the wall of the structure or mounted independently from the structure the mounting may be of a fixed orientation or may be adjustable so as to intercept the optimum amount of solar energy throughout the day or throughout the year connecting the solar energy collectors 10 and the interior space of the structure are inlet manifold 37 and outlet manifold 46 in operation diffuse or direct sunlight strikes the transparent top wall 22 of the solar energy collecting device 10 and is transmitted to the interior chamber 13 where it strikes the surface of the solar energy absorbing material 52 thereby raising its temperature.
