Abstract

Modular collector panels are adapted for flush or recessed mounting on a pitched roof, or may be installed on a flat roof by means of a mounting frame, the panel sections being interconnected in side-by-side relation to one another by a unique form of side and end wall connector assembly which serves to interconnect the panels in sealed relation to one another to the roof or other housing as well as to support and house the component parts of the panel section including the glazing, absorber plate and insulating layer in unitary relation to one another.

an outer enclosure for each panel section including a bottom panel, opposite sidewall panels and opposite end wall panels, each sidewall panel defined by an elongated bracket extending the length of said panel section including a lower inwardly offset portion including means for connection to the roof surface and terminating in a lower edge adjoining a lateral edge of said bottom panel and an upper lateral projection forming a continuous ledge projecting inwardly toward the opposite sidewall panel, each end wall panel extending along an opposite end of each panel section having a lower edge adjoining an edge of said bottom panel and an upper removable access strip extending continuously along at least one end wall panel including an upper ledge aligned with said ledges on said sidewall panels to cooperate therewith in supporting said glazing layer in spaced relation above said absorber plate; and

interconnecting means for interconnecting adjoining sidewalls of adjacent panel sections together including a retainer plate, a cap strip overlapping upper edges of said adjoining sidewalls and fastener means extending through said cap strip to anchor said cap strip to said retainer plate.

8. In a solar collector panel assembly according to claim 7, including a first cap flashing member extending from the roof at one end of each panel section having a return portion interposed between said cap strip and the upper edge of said end wall bracket for each panel section along one end wall thereof.

9. In a solar collector panel assembly according to claim 8, including a second cap flashing member extending from the opposite end wall for attachment to the roof.

10. In a solar collector panel assembly according to claim 7, each end wall panel including a lower bracket joined to the end of said bottom panel and extending vertically upwardly therefrom, and said upper removable access strip including a straight vertical portion having a lower downwardly facing return portion at its lower edge adapted to be releasably connected to the upper edge of said lower bracket, a duct opening extending therethrough, and an upper inwardly directed edge at the upper extremity of said access strip.

11. In a solar collector panel assembly according to claim 7, each said sidewall panel being in the form of a unitary bracket in which said glazing layer supporting ledge is slotted to receive said retainer plate.

12. In a solar collector panel assembly according to claim 7, wherein said lower offset portion is defined by an inwardly stepped shoulder portion.

13. In a solar collector panel assembly adapted for mounting on a pitched roof, said assembly having a plurality of generally rectangular, modular panel sections, each section including an absorber plate, thermal fluid conducting means associated with said absorber plate and communicating with supply and return lines at opposite ends of each said panel section, an insulating layer beneath said absorber plate and an upper glazing layer disposed above said plate, the improvement comprising:

an outer enclosure for each panel section including a bottom panel, opposite sidewall panels and opposite end wall panels, each sidewall panel defined by an elongated bracket extending the length of said panel section including a lower panel portion including means for connection to the roof surface and terminating in a lower edge adjoining a lateral edge of said bottom panel and an upper laterally projecting return forming a continuous ledge projecting inwardly toward the opposite sidewall panel, each end wall panel extending along an opposite end of each panel section having a lower bracket adjoining an edge of said bottom panel, and an upper removable access strip extending continuously along each end wall panel including an upper ledge aligned with said ledges on said sidewall panels to cooperate therewith in supporting said glazing layer in spaced relation above said absorber plate; and
