A composite insulating panel

摘要

A photovoltaic solar collector (10) is mounted to a profiled external sheet (2) of an underlying composite insulating panel. The solar collector (10) comprises a photovoltaic sheet (20) and a protective translucent cover (21) for the photovoltaic sheet (20). A first adhesive layer (22) is provided between the photovoltaic sheet (20) and the translucent cover (21). A second adhesive layer (23) is provided between the underside of the photovoltaic sheet (20) and the external surface of the composite panel upper or external sheet (2). The adhesive layers (22), (23) may be of the same hot melt adhesive. In the invention sheets of the photovoltaic (20), the adhesive (22), (23), and the cover (21) are drawn from supply reels, are cut to length, and then laid on top of the upper sheet (2) of the insulated panel. Using a pressure laminating process the various layers are heated and pressed to adhere to and conform to the outer sheet 2 of the insulated panel.
