A composite insulating panel comprises an external sheet 2, an internal sheet 4, and an insulating body 5 between the sheets 2, 4. The external sheet 2 has a first longitudinally extending raised side underlap projection 30 at one side and a side overlap projection 31 on the opposite side of the panel with a substantially flat portion 32 extending between the projections 30, 31. A photovoltaic solar collector 10 is mounted to the flat portion 32 of external sheet 2. 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 21, 22 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 flat portion 32 of the upper sheet 2 of the insulated panel. Using a pressure laminating process the various layers are heated and pressed to adhere to the flat portion 32 of the outer sheet 2 of the insulated panel. |
