Solar cell roofing structure and the solar cell panels used therein

Abstract

Title of the invention is Solar Cell Roofing Structure And The Solar Cell Panels Used Therein. As a roofing material, the solar cell panels are supported on a fireproof, non-inflammable material in such a way as to secure cooling air flow channels under the panels. Such a technology is aimed at guaranteeing durable and effective weathering and achieving cost reduction. These aims can be accomplished by the following means: The solar cell panel (19) which comprises a solar cell (1) disposed under tempered glass plate (8), an extension for lap roofing at the lower edge of said panel, and a metal sheet (20) integrated with said panel and having the bottom extended from the upper edge of said panel for the overlapping with the metal sheet of the upper panel, wherein said metal sheet is folded to give a projection (20a) for support at the center of panel width and to give embankments (20b) for support and hold on both the longitudinal sides of said panel. With this panel as a roofing module, the panels (19) are laid on the roof adjacently to one another in the slope direction as well as in the direction perpendicular to the slope. In laying the panels on the roof, the upper panel is laid so that its extension will settle on the upper edge of the lower panel, and in turn the metal sheet (20) of the upper panel is overlapped with the extended metal sheet bottom of the lower panel. The two embankments (20b) sitting face to face on the same rafter (27) are covered with a groove-like bending member (28) in the shape of a glass presser foot, and are fixed by the bead (30), wherein said bead (30) is also overlapped with upper bead (30) in the lap-roofed area where the upper panel (19) settles on the upper edge of the lower panel (19). FIG. 11 is designated for the understanding of this invention.
