Solar panel element

Abstract

The purpose of this invention is to indicate a solar panel element, wherein the solar panel element may constitute an integrated and aesthetically attractive covering element for covering a building envelope, where the solar panel element can be mounted without changing possibly existing underlying structures and follow the architecture in the surrounding covering of the building. Moreover, it is aimed at mounting a solar panel element which is completely or partially produced under quality-assuring conditions. This purpose is achieved by a solar panel element consisting of a transmission plate, an absorber housing and an absorber member. The solar panel element according to the invention is peculiar in that the transmission plate has greater extension than the absorber housing, and that the transmission plate, compared with the absorber housing, has a protruding part, preferably for overlapping on a roof or façade element.

         12 . A solar panel element for installation in relation to a surrounding covering, for thermal utilisation of solar radiation, the solar panel element constituting a roof or facade element for covering a building, the solar panel element including a transmission sheet or plate, an absorber member and an absorber housing, where the transmission plate is adapted for passage of solar radiation, where the absorber member includes means for transforming solar radiation to heat radiation/heat conduction and for transmitting the heat radiation/heat conduction to at least one tube which is connected with the absorber member, and which is intended for containing a heat absorbing liquid medium, where the absorber housing includes connecting means for the transmission sheet or plate, where the solar panel element is provided with projecting means along one or more edges, where these means form direct or indirect transition to the surrounding covering and at the same time are an extension of the transmission plate, said surrounding covering forming lines in a longitudinally, crosswise and/or obliquely direction, said lines being foamed by the profile and/or edge of individual covering elements, wherein the transmission plate or plates are provided with arrange able means for indicating lines having a longitudinally, crosswise and/or obliquely direction. 
     
     
         13 . Solar panel element according to  claim 12 , wherein the transmission plate is composed of a number of transmission elements, e.g. of the same size as diagonal slate or tile elements. 
     
     
         14 . Solar panel element according to  claim 12 , wherein the solar panel element is designed corrugated, e.g. as corrugated fibre-cement board or roof tiles, and that the projecting means are adapted to, or designed to be adapted to, surrounding covering elements. 
     
     
         15 . Solar panel element according to  claim 12 , wherein the solar panel element at least at one side and preferably at several sides includes a flashing, where the flashing as well as the solar panel element is designed such that the flashing is hidden by the surrounding covering elements, alternatively by the projecting means. 
     
     
         16 . Solar panel element according to  claim 12 , wherein the absorber member is spaced apart from the transmission plate, and that the spacing between the absorber member and the transmission plate is constituted by at least one cavity, wherein the at least one cavity preferably contains a gas which is heavier than atmospheric air or provided with a pressure which is less that atmospheric pressure. 
     
     
         17 . Solar panel element according to  claim 12 , wherein the spacing between the absorber member and the transmission plate is constituted by a number of cavities with limited mutual communication. 
     
     
         18 . Solar panel element according to  claim 17 , wherein the limited mutual communication between the cavities is constituted by one or more secondary transmission plates which preferably lie substantially in parallel with the absorber member. 
     
     
         19 . Solar panel element according to  claim 17 , wherein the limited mutual communication between the cavities is constituted by one or more barrier members connected with the transmission plate or with the absorber member. 
     
     
         20 . Solar panel element according to  claim 16 , wherein the limited mutual communication between the cavities is constituted by barrier members which constitute a barrier element, such as a rib element, wherein the cavities between the ribs may assume any geometric shape, e.g. rectangular, triangular, hexagonal, circular, oval or combinations of several geometrical shapes. 
     
     
         21 . Solar panel element according to  claim 12 , wherein the transmission plate as well as the absorber member, and alternatively also the bottom surface of the absorber housing, are provided with corresponding or substantially uniform corrugations.
