Cover panel for capturing solar energy

Abstract

Solar energy collector roofing panel, includes a metal sheet ( 1 ), a series of metal ducts ( 2 ) fixed to the sheet, and a layer of insulating material ( 4 ) covering the ducts. The set of ducts defines a continuous circuit connectable to the circuit of another adjacent panel or to ducts of an external circuit.

1 . Solar energy collector roofing panel, comprising: a metal sheet, a series of parallel metal ducts fixed to one surface of the metal sheet; and a layer of insulating material arranged on the metal ducts; the ducts being consecutively connected by their adjacent mouths, defining a continuous circuit which is open at a free mouth of the end ducts, for connection to the circuit of another adjacent panel or to ducts of an external circuit, wherein the metal sheet has, in a direction perpendicular to the metal tubes, a stepped profile coinciding with the one a profile formed by slate covering pieces which are coupled on said metal sheet, the slate covering pieces being in contact with the metal sheet and fixed to an outer surface of the metal sheet by a high thermal transmission material. 
     
     
         2 . (canceled) 
     
     
         3 . Panel according to  claim 1 , further comprising a water proofing sheet inserted between the metal sheet and the insulating material layer, from at least one of the edges of the panel parallel to steps of the stepped profile of the metal sheet, which protrudes from said edge in an overlapping strip. 
     
     
         4 . Panel according to  claim 1 , wherein the metal sheet protrudes, with respect to the insulating material layer and tubes, from at least one of the edges perpendicular to the stepped profile. 
     
     
         5 . Panel according to  claim 1 , wherein the insulating material layer has, on a free surface, a finish coating fixed thereto. 
     
     
         6 . (canceled) 
     
     
         7 . Panel according to  claim 1 , further comprising along at least one of the edges perpendicular to the stepped profile of the metal sheet a gutter which rests on a lower support. 
     
     
         8 . Panel according to  claim 7 , wherein the lower support on which the gutter rests is formed by an extension of the finish coating of the panel which constitutes the inner visible surface thereof. 
     
     
         9 . Panel according to  claim 7 , wherein the gutter extends beyond one end of the support on which the gutter is mounted in a section for the overlapping with the gutter of the panel located on a next adjacent panel.
