    or walls are further aesthetically unattractive in that they have a construction and shape that differs from that of the building.
    Because they are placed on roofs and thus can be removed, they are, if applicable, prone to theft. In addition, they tend to collect dirt, leaves and the like. Because they are exposed on the ceiling or wall, they are exposed to external damage such as hail, falling branches or the like.
    In addition, the life of such devices is limited.
    FR2499693A1 discloses a light absorbing unit for heating a liquid medium via a transparent surface layer by solar energy comprising a channel configuration in the form of hoses inside said transparent surface layer in which said liquid medium is arranged to flow for said heating, the light absorbing means forming and the hoses enclosing upper and lower plate forming thermal contact are present. The unit further comprises an inner transparent layer for thermally insulating said duct configuration of said liquid medium from the ambient air. The light-absorbing unit is intended to form an integral part of a roof construction. The light-absorbing unit is arranged to support roof tiles.
    OBJECT OF THE INVENTION An object of light absorbing unit for a liquid medium which enables simple with the present invention is to provide a and time-efficient manufacture and installation, is easy to apply and has a long service life.
    SUMMARY OF THE INVENTION This and other objects, which will become apparent from the following description, are accomplished by means of a light absorbing unit of the kind initially indicated and further having the features set forth in the characterizing part of the appended independent claims 1. Preferred embodiments of the light absorbing unit defined in the invention are claims 2-11.
    According to the invention, the objects are achieved with a light absorbing unit for heating via a transparent surface layer at least one liquid medium by solar energy comprising a channel configuration within said transparent surface layer in which said liquid medium is arranged to flow for said heating, wherein light absorbing means are substantially said channel configuration, which light-absorbing unit is intended to form an integral part of a roof construction, said transparent surface layer comprising transparently arranged roof tiles arranged to be supported by means of supporting batten, said supporting batten being arranged to form part of said light-absorbing unit in said roof construction, support battens are arranged to be fitted in said roof construction with said light absorbing unit.
    This enables simple and time-efficient installation of the light-absorbing unit during integration in roof construction in that the supporting batten is already applied to the light-absorbing unit when applied to a beam batten of the roof construction so that no supporting batten needs to be laid before the light-absorbing unit is applied. Because the batten is arranged to be fitted in the roof structure with the light-absorbing unit and consequently forms part of the light-absorbing unit, no adjustment is required due to deviations in the distance between baffles, which is the case with conventional baffles arranged on the roof, whereby for optimized effect.
    According to one embodiment, said light-absorbing unit is configured substantially parallelepipedically and said support batten is arranged to run and is supported along a longitudinal side of said light-absorbing unit, which long side is intended to run substantially horizontally in said roof construction.
    According to an embodiment of the light-absorbing unit, said support batten comprises an upper portion as a support for roof tiles arranged to protrude over a top side of said light-absorbing unit. This facilitates the application and support of roof tiles at the same time as the risk that the edge of the roof tiles at the supporting batten does not risk touching and damaging the top of the light-absorbing unit.
    According to an embodiment of the light-absorbing unit, said support batten has a substantially L-shaped cross-section transverse to its longitudinal direction and wherein a foot portion of said L-shaped cross-section is arranged to constitute spacers between two adjacent light-absorbing units. This further facilitates the installation in that adjacent light-absorbing units are easily applied in the correct position next to an already applied light-absorbing unit.
    Furthermore, optimization of the effective absorber surface which is included by the top of the light absorbing unit is enabled.
    According to an embodiment of the light-absorbing unit, said upper portion is shorter across the longitudinal direction of the support batten than said foot portion.
    This enables optimization of the effective absorber surface which is included by the upper side of the light-absorbing unit while at the same time giving space for supporting roof tiles in connection with the supporting batten.
    According to an embodiment of the light absorbing unit, said upper portion has a downwardly open substantially U-shaped configuration. This facilitates the support of roof tiles. The U-shaped configuration of the upper portion of the support batten further facilitates connection to roof tiles via a connecting member.
    According to an embodiment of the light-absorbing unit, said roof tiles are intended to be connected to said support batten by means of a connecting means arranged to act between a roof tile and the support batten.
    This enables easy connection of the support batten and roof tiles. This facilitates compliance with statutory requirements for connection of roof tiles in a roof structure. This improves the roof's tightness and walkability. Furthermore, the risk of roof tiles coming loose in the event of strong winds, for example, is reduced.
    According to an embodiment of the light absorbing unit, said connecting means comprise an upper fastening portion arranged to be attached to a roof tile and a lower fastening portion arranged to be mounted at the supporting batten, said fastening portions being arranged to hold said connecting means to said roof tile. This enables efficient connection between the roof tile and the batten.
    According to an embodiment of the light-absorbing unit, said lower fastening portion is arranged to cooperate with said upper portion of said support batten.
    In this way, an efficient connection is obtained between the roof tile and the supporting batten.
    According to an embodiment of the light-absorbing unit, said lower fastening portion has an upwardly open substantially U-shaped configuration for said interaction. This results in a good connection between roof tiles and the support batten in that the U-shaped configuration of the lower fastening portion hooks into the U-shaped configuration of the upper part of the support batten for said connection.
    According to an embodiment of the light absorbing unit, said layer for channel configuration of said liquid medium to the surrounding upper surface comprises a transparent thermally insulating said air. This improves the efficiency of the light-absorbing device.
