Thermal insulating sheet metal panel with photovoltaic element for a roof covering or wall cladding

Abstract

The invention relates to a sheet metal panel for a roof covering or wall cladding, having two cover sheets ( 1, 2 ) and an intermediate layer ( 11 ) of thermal insulating material. Applied to the cover plate ( 2 ) of the panels forming the outside is a plane photovoltaic element ( 17, 18 ) which has electric connecting cables ( 21, 22 ) and which takes the form of a flexible laminate having a cold-bonding adhesive ( 19, 20 ) on its rear side and whose electric connecting cables ( 21, 22 ) extend through bores ( 23 ) in the sheet metal panel, which are sealed with respect to physical constructional demands.

1 . A sheet metal panel (P, P*) for a roof covering or wall cladding, having two cover sheets ( 1 ,  2 ) and an intermediate layer ( 11 ) of thermal insulating material, characterised in that applied to the cover plate ( 2 ) of the panels forming the outside is a plane photovoltaic element ( 17 ,  18 ) which has electric connecting cables ( 21 ,  22 ) and which takes the form of a flexible laminate having a cold-bonding adhesive ( 19 ,  20 ) on its rear side and whose electric connecting cables ( 21 ,  22 ) extend through bores ( 23 ) in the sheet metal panel (P P*), which are sealed with respect to physical constructional demands.  
     
     
         2 . A sheet metal panel according to  claim 1 , characterised in that the photovoltaic element ( 17 ,  18 ) is built up from amorphous silicon cells.  
     
     
         3 . A sheet metal panel according to claims  1  or  2 , characterised in that the adhesive ( 19 ,  20 ) is a layer of bituminous material.  
     
     
         4 . A sheet metal panel according to one of  claims 1  to  3 , characterised in that the bores ( 23 ) in the cover sheet ( 1 ) forming the underside are provided with a closure ( 26 ) acting as a vapour barrier.
