A self-cooling solar forced air heating collector module, and method of constructing a plurality of the same in modularized array from standarized components, for a solar heating system. The collector has an inner heating compartment beneath an inner glazing, and an outer heating compartment between the inner glazing and an outer glazing. A forced air inlet duct enters the collector bottom surface and communicates directly only with the outer compartment at a given location longitudinally of the collector. An always-open passage effects air flow communication from the outer to the inner compartment, at one longitudinal end thereof remote from the inlet duct. A sole outlet duct extends through the bottom surface and communicates directly only with said inner compartment in the vicinity of the inlet duct. A black body absorber comprising an air-permeable single layer screen extends within the inner compartment such that the forced air flows along and in the same direction on both sides of the screen. The collector is oriented in operation for solar incidence transverse to the glazings with its lengthwise dimension horizontal and its width dimension tilted at an angle between 10°through 90°from horizontal. Upon cessation of forced air flow via the ducts, whereupon a stagnation condition occurs in the collector, the air trapped therein automatically circulates within the collector and to and from the compartments via the always-open passage in response to solar-incidence-induced convection currents, thereby producing a self-cooling action.

A solar collector construction adapted to be mounted to a supporting surface inclined at any angle from vertical to horizontal comprising a sill beam adapted to extend horizontally along the supporting surface and at least a head beam adapted to extend parallel to said sill beam and adapted for mounting to said supporting surface so as to form an opposite side wall of said solar collector, an end jamb extending perpendicularly to said head and sill beams to define one end wall of said solar collector, a manifold turnaround jamb extending perpendicularly between said sill and head beams and spaced longitudinally of the collector from said end jamb to define an opposite end wall of said collector, said beams and jambs each comprising an aluminum extrusion having a generally I-shaped cross-sectional configuration defined by a bottom flange adapted for mounting against said supporting surface by fasteners, a top flange protruding laterally from the opposite sides of a center web of the cross section, the portion of the top flange protruding internally within the collector towards one another providing a shelf for mounting of an outer glazing light array on said collector, the portion of said top flange protruding laterally outwardly externally of said collector providing a mounting surface for surrounding weather-proof flashing, a plurality of cap strips secured to the upper edges of said beams and jambs in superimposed relation to said outer glazing and surrounding flashing to clamp the same against the top flanges of said beams and jambs, said beams and said end jamb each having an intermediate flange protruding laterally from the center web thereof interiorly of said collector to form a shelf intermediate said top and bottom flanges of said beams and jamb for supporting an inner glazing lite array thereon, said beams and end jamb each further having a pair of longitudinally extending hook flanges spaced laterally from one another and protruding from the interior side of said center web in the space between said intermediate flange and the interior portion of said top flange, a plurality of retainer channels of generally C-shaped cross-sectional configuration having a pair of free end edges engaged respectively with said hook flanges and surmounting the adjacent edges of said inner glazing lite array to clamp the same against said intermediate flanges of said beams and end jamb, and a black body mounted in the space between said inner glazing lite array and said bottom flanges of said beams and jambs.
