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 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. A photovoltaic solar collector (10) is mounted to the flat portion of external sheet. The solar collector comprises a photovoltaic sheet and a protective translucent cover for the photovoltaic sheet. A first adhesive layer is provided between the photovoltaic sheet and the translucent cover. A second adhesive layer is provided between the underside of the photovoltaic sheet and the external surface of the composite panel upper or external sheet. The adhesive layers may be of the same hot melt adhesive. Sheets of the photovoltaic, the adhesive and the cover are drawn from supply reels, are cut to length, and then laid on top of the flat portion of the upper sheet of the insulated panel. Using a pressure laminating process the various layers are heated and pressed to adhere to the flat portion of the outer sheet of the insulated panel. |
