RELATED APPLICATIONS 
     The present application is the national phase of International Application No. PCT/EP2020/062752, filed on May 7, 2020 which claims priority to and the benefit of German Patent Application No. 10 2019 111 888.3, filed on May 7, 2020, and the disclosures of which are hereby incorporated herein by reference in their entireties. 
    
    
     ADVANTAGES OF THE INVENTION 
     A floating carrier device is proposed that is configured to support at least one solar element floating on a water body, in particular an inland water body, with at least one floating body and with a carrier structure which is coupled with the floating body and is configured to transfer a support force of the at least one solar element to the at least one floating body. 
     By a “floating body” is herein in particular a body to be understood that generates a buoyancy force. In particular, by a floating body is a hollow body to be understood with one hollow space or a plurality of hollow spaces, preferably with one single contiguous hollow space. 
     The carrier structure is preferentially configured to transfer away support forces, in particular to a floating body. Preferably the carrier structure is embodied at least largely of metal. Particularly preferably the carrier structure is embodied at least largely of steel. The phrasing “at least largely” or “at least to a large extent” is here in particular to mean by at least 55%, advantageously at least 65%, preferentially at least 75%, particularly preferably at least 85% and especially advantageously at least 95%. 
     By an implementation according to the invention it is possible to achieve a solar device which is particularly flexibly implementable. Furthermore an implementation according to the invention provides an easy assembly with favorable production costs and with a compact construction. 
     It is further proposed that the floating body comprises on at least one side wall a receiving region for the carrier structure, as a result of which the support forces are particularly advantageously introducible. 
     A “side wall” is preferably a wall of the floating body whose envelope section faces toward a reference side face of a smallest imaginary reference rectangular cuboid, the reference rectangular cuboid just still completely enclosing the floating body. 
     An “envelope” is preferentially an, in particular geometrically smallest, preferably free geometry enveloping a body, the geometry being in particular free of inflection points. 
     The, in particular smallest imaginary, reference rectangular cuboid preferentially comprises, preferably in an assembled operation state of the floating body, a reference upper side and a reference underside. The reference upper side and the reference underside are in particular arranged at least substantially parallel to a preferably ideal water surface. The reference rectangular cuboid comprises reference side faces. In particular, preferably in an assembled operation state, the reference side faces are arranged perpendicularly to the ideal water surface. “Facing toward” is in particular to mean, in this context, that a surface faces towards a reference surface if a surface normal of the surface, in particular of an envelope section of the floating body, comprises relative to a reference surface normal of the reference surface, in particular of a reference rectangular cuboid, a parallel component having an absolute value that is greater than/equal to 50% of the absolute value of the surface normal. In particular, the side wall is configured to connect an upper side and an underside of the floating body to each other. 
     The ideal water surface preferably extends in a horizontal plane and is in particular free of waves and flows and other perturbations. Preferentially an earth curvature is neglected in particular for an illustration of the ideal water surface. 
     The term “substantially perpendicularly” is here in particular intended to define an orientation of a direction relative to a reference direction wherein, in particular viewed in a plane, the direction and the reference direction include an angle of 90 degrees. and the angle has a maximum deviation that is in particular smaller than 8 degrees, advantageously smaller than 5 degrees and especially advantageously smaller than 2 degrees. Furthermore a “main extension plane” is preferably to be understood as a plane of a body, in particular of a floating body, that extends parallel to a largest side face of a smallest imaginary reference rectangular cuboid just still completely enclosing the body, in particular the floating body, said plane in particular extending through the center point of the reference rectangular cuboid. In particular, in an assembled operation state the main extension plane extends at least substantially perpendicularly to the ideal water surface. 
     By a “receiving region” is in particular a region to be understood that forms a support surface for a support of support forces. The receiving region in particular comprises a receiving contour. Preferably the support surface is formed by the receiving contour. The receiving contour is preferentially configured for a delimitation of the receiving region. By a receiving region being arranged on at least one side wall of the floating body is in particular to be understood that in a region of the side wall a receiving region is arranged, which is preferably embodied as an elevation and/or deepening. Particularly preferably the receiving region is embodied as a deepening in a region of the side wall. Beyond this it would be conceivable that the receiving contour, in particular the receiving region, may preferably be implemented in an L-shape and/or U-shape and/or T-shape and/or C-shape and/or Omega-shape and/or V-shape and/or O-shape and/or as a combined shape or as a multiple combination. 
     Furthermore it is proposed that the floating body comprises a receiving region for the carrier structure at least on an upper side, thus allowing an especially advantageous introduction of the support forces Preferentially an upper side of the floating body is a wall of the floating body whose envelope section faces towards the reference upper side of the, in particular smallest, imaginary rectangular cuboid enclosing the floating body, which preferably just still completely encloses the floating body. Furthermore an underside is a wall of the floating body whose envelope section faces towards the reference underside of the, in particular smallest, imaginary rectangular cuboid enclosing the floating body. The upper side is preferably arranged above the water surface, in particular in a space. Especially preferentially the upper side of the floating body has in an assembled operation state a distance to the, in particular ideal, water surface. It is moreover proposed that the floating body comprises the receiving region for the carrier structure at least on the side wall and/or on the upper side. 
     It is also proposed that the receiving region is implemented integrally with the floating body, resulting in a particularly advantageous reduction of production costs and/or assembly costs being achievable. “Integrally” is in particular to mean at least connected by substance-to-substance bond, for example by a welding process, a gluing process, an injection-molding process and/or any other process that is deemed expedient by someone skilled in the art, and/or advantageously formed in one piece, for example by a production from a cast and/or by a blow procedure, in particular an extrusion blow procedure, and/or by a production in a one-component or multi-component injection-molding procedure, and/or especially advantageously from a single blank. The receiving region is in particular integrally molded with the floating body. In particular, the receiving region is implemented by an extrusion blow procedure in such a way that it is integrally molded with the floating body. 
     Furthermore it is proposed that the receiving region is configured for a form-fit accommodation of the carrier structure, as a result of which an advantageously time-efficient and/or non-destructive assembly is achievable at low material costs. The term “form-fit” is in particular to mean that surfaces, which are situated opposite each other in an assembled operation state, exert a holding force onto each other that acts in a normal direction of the surfaces. In particular, the structural components are in a geometrical engagement with each other. In particular, the surfaces are configured to preferably transfer support forces from the form-fit accommodation to the carrier structure. It is preferentially possible for the surfaces to have a spacing between each other in an assembled operation state. 
     It is moreover proposed that the floating body is produced at least substantially via an extrusion blow procedure, as a result of which an advantageously precise outer surface can be defined and/or structured in one work step and an advantageously cost-efficient production process can be made available. 
     The floating body is preferably embodied of a thermoplastic material. In particular, the floating body is embodied of a food-safe material. Particularly preferably the floating body is made of an HDPE plastic material. In particular, the extrusion blow procedure is configured for forming the floating body from a flexible-tube-like pre-form. In the extrusion blow procedure preferentially a negative tool, in particular of the floating body, is utilized. In particular, the negative tool has on its inner side structural features of an end product, in particular an intended shape of the floating body. 
     A hollow-body production by means of a “stretch-blow molding procedure” is also conceivable, as well as any other production method deemed expedient by someone skilled in the art. 
     Beyond this it is proposed that the floating body comprises at least two stack elements, which are implemented and/or arranged correlating with each other and which are configured to bring at least two floating bodies to a laterally form-fit engagement with each other. This allows achieving an advantageous space efficiency and/or transport efficiency. It is thus particularly advantageously possible to achieve a reduction of logistics costs. 
     “Implemented correlating with each other” is in particular to mean, in this context, that at least one first element, in particular stack element, and at least one further element, in particular stack element, are configured to be brought to an engagement with each other. Furthermore, in particular two elements, in particular stack elements, which are preferably implemented correlating with each other, are preferably embodied in a form-fit manner for a lateral force transfer. A lateral force transfer is preferentially effected in a direction that is at least substantially perpendicular to an earth acceleration. In particular, a smallest cross section measurement of the at least one first element, in particular stack element, is larger than a largest cross section measurement of the at least one further element, in particular stack element, that is embodied correlating with the at least one first element. Especially preferentially the stack elements are implemented such that they are correlating with each other, in particular geometrically. Moreover, preferably an inner contour of a first element, in particular stack element, is implemented in such a way that it is structurally identical and reduced in size relative to an outer contour of a further element, which is in particular implemented correlating thereto. The inner contour is preferably implemented as an enlargement of the outer contour. Preferably the outer contour, in particular the outer contour of the at least one first element, is configured to receive the inner contour, in particular the inner contour of the at least one further element. 
     The stack elements are preferably configured to prevent a slippage and/or sliding off of a floating body, in particular of a floating body that is arranged above a further floating body. A lateral form-fit is preferably configured for a delimitation of a horizontal movement, in particular at least substantially perpendicularly to the earth acceleration. Preferentially at least two floating bodies are configured to be stacked onto each other in a stacking direction on a stack axis. The stack elements are preferably configured to delimit, in particular in a form-fit manner, a movement perpendicularly to the stacking direction. 
     In particular, at least one first stack element is arranged on the underside of the floating body. Furthermore, in particular at least one further stack element is arranged on the upper side of the floating body. Preferably the at least one first stack element is arranged in a manner correlating with the at least one further stack element. In particular, the at least one first stack element and the at least one further stack element are preferably arranged on the floating body such that in particular at least two, preferably structurally identical floating bodies, which are in particular brought to an engagement with each other by means of stack elements, comprise reference side faces of the reference rectangular cuboid which are arranged at least substantially without offset and parallel. In particular, main extension planes of at least two floating bodies that are stacked together preferably lie in a shared plane, preferably at least substantially without offset. “At least substantially without offset” is in particular to mean, in this context, a lateral deviation, preferably perpendicularly to a stacking direction, that is in particular smaller than 20 mm, preferentially smaller than 15 mm, preferably smaller than 10 mm and particularly preferably smaller than 5 mm, as well as an angle deviation that is in particular smaller than 10 degrees, preferentially smaller than 8 degrees, preferably smaller than 5 degrees and particularly preferably smaller than 3 degrees. Preferentially the two stack elements which are implemented correlating with each other are arranged on an upper side and an underside of the floating body, preferably in a manner correlating with each other. In particular, the two stack elements which are preferably arranged correlating with each other comprise surfaces which are in particular implemented geometrically correlating with each other. Preferably the stack elements which are implemented correlating with each other, in particular on a floating body, are arranged at least substantially parallel to each other. The stack elements are furthermore preferably implemented integrally with the floating body. Further the stack elements in particular have a rectangle shape and/or spheric shape and/or conic shape and/or elliptic shape and/or parabolic shape and/or wave shape and/or saw-tooth shape and/or pyramidal shape and/or furrowed shape and/or a combination at least of the above-mentioned shapes. Particularly preferably the stack elements are embodied on a surface of the floating body as a macroscopic structure. By a “macroscopic structure” is here in particular an implementation to be understood that forms an elevation and/or deepening that goes beyond a plane spanned by a surface, that in particular goes beyond a mere and/or increased roughness of a material. In this context the macroscopic structure preferentially comprises an elevation and/or deepening perpendicularly to the plane of the spanned surface by in particular more than 1 mm, preferably more than 3 mm, preferentially more than 5 mm and particularly preferably more than 10 mm. The macroscopic structure further comprises, in this context, preferably an elevation or deepening perpendicularly to the plane of the spanned surface by in particular less than 65 mm, preferentially less than 55 mm, preferably less than 45 mm and particularly preferably less than 35 mm. 
     It is further proposed that at least one of the stack elements is implemented as a deepening and at least one further stack element of the stack elements is implemented as an elevation that is realized correlating with the deepening. In this way an advantageously high level of efficiency of the stackability of the floating bodies is achievable in an advantageously simple manner, at high cost-efficiency and low production effort. Preferably, perpendicularly to the spanned plane of the surface, preferentially in a parallel and/or in an anti-parallel direction of a surface normal of the reference upper side and/or of the reference underside, the elevation and/or the deepening are/is greater than 4 mm, preferably greater than 15 mm and very particularly preferably greater than 200 mm. 
     Moreover it is proposed that the floating body is implemented at least partly with an anti-skid implementation. An outer surface of the floating body preferably has, relative to a smooth surface of a floating body material, an increased friction, in particular static friction and/or kinetic friction. Furthermore, at least one outer surface of the floating body at least partly comprises an increased anti-skid implementation regarding a slide-enhancing substance, in particular water. In particular, the anti-skid implementation is embodied integrally with the floating body. Preferably the anti-skid implementation is embodied as an anti-skid covering. In particular, the anti-skid implementation is embodied as a mat, in particular a rubber mat, and/or as a textured structure and/or as a foil and/or as a granulate and/or as a foam. Especially preferentially the anti-skid implementation is embodied as a macroscopic structure. Preferably, the macroscopic structure has, in this context, an elevation and/or deepening perpendicularly to the plane of the spanned surface by in particular more than 0.3 mm, preferentially more than 0.8 mm, preferably more than 1 mm and particularly preferably more than 1.5 mm. Preferentially the macroscopic structure furthermore has, in this context, an elevation and/or deepening perpendicularly to the plane of the spanned surface by in particular less than 35 mm, preferably less than 20 mm, preferentially less than 10 mm and particularly preferentially less than 5 mm. The macroscopic structure, in particular macroscopic anti-skid structure, is in particular implemented as a planar arrangement of elevations and/or deepenings. Preferably the macroscopic structure is in particular realized as a lattice structure and/or nub structure and/or furrowed structure and/or serrated structure and/or cross-wise structure and/or textured structure and/or fiber structure and/or pyramidal structure and/or circular structure and/or honeycomb structure and/or triangle structure and/or of structures which are at least partially superimposed with each other. 
     Advantageously by way of an anti-skid implementation a slippage risk is reduced and an operational safety is augmented. Furthermore, an implementation is conceivable of the, in particular anti-skid, macroscopic structure as at least one stack element. 
     Furthermore it is proposed that in an assembled operation state the floating body at least partly has a decreasing maximum transverse extension perpendicularly to the ideal water surface, along a direction from the upper side to the underside of the floating body. 
     In particular, the floating body has a decreasing maximum transverse extension in a direction of a surface normal of the reference underside of the floating body. In an assembled operation state the floating body is preferably arranged at least partly above a water surface. In an assembled operation state the floating body is preferentially arranged below the ideal water surface, in particular over more than 20%, preferably over more than 40% and particularly preferably over more than 50% of the maximum extension of the floating body along the vertical axis. 
     In particular, in an assembled operation state the floating body is accommodated in the carrier structure of the floating carrier device, which is in particular arranged floating on and/or in a water body having a water surface. By a “vertical axis” is in particular, in this context, an axis to be understood which in particular extends perpendicularly to a water surface. In particular, a vertical axis extends along the direction of the surface normal of the reference upper side and/or of the reference underside, preferably of the smallest imaginary rectangular cuboid of the floating body. Preferentially the upper side of the floating body is implemented in particular in a curved manner, preferably at least partly in a convexly and/or concavely curved manner. It is further conceivable that the upper side of the floating body is at least largely embodied in a planar fashion. Preferentially the underside of the floating body is embodied in a curved manner, preferably at least partly in a convexly and/or concavely curved manner. Moreover it is conceivable that the underside of the floating body may be embodied in a planar fashion, at least to a large extent. Preferentially, the, in particular entire, decreasing maximum transverse extension has a value, in particular a difference value between a maximum transverse extension and a minimum transverse extension, namely in particular a transverse extension of the underside of the floating body, perpendicularly to the vertical axis, that is preferably greater than 5 cm, preferentially greater than 10 cm and particularly preferably greater than 15 cm. Furthermore the, in particular entire, decreasing maximum transverse extension preferably has a value, in particular a difference value between a maximum transverse extension and a minimum transverse extension, namely in particular a transverse extension of the underside of the floating body, perpendicularly to the vertical axis, that is preferentially smaller than 45 cm, preferably smaller than 35 cm and particularly preferably smaller than 25 cm. Preferentially the underside of the floating body has the smallest transverse extension. Preferably the transverse extension decreases over at least a substantial portion of a maximum extension of the floating body along the vertical axis, in particular towards the underside of the floating body, i.e. in particular over more than 20%, preferentially over more than 40% and especially preferentially over more than 50% of the maximum extension of the floating body along the vertical axis. 
     An at least partially decreasing maximum transverse extension of the floating body along a vertical axis, in particular from the upper side of the floating body and/or from the water surface to the underside of the floating body, may contribute to a particularly advantageous flexible applicability of the floating body and/or of the floating carrier device. It is advantageously possible to utilize the floating body and/or the floating carrier device in freeze-risk water bodies. Especially advantageously a robustness is enhanced with respect to external conditions, in particular with respect to an ice pressure. Due to an implementation of the floating body according to the invention, an ice pressure will push at least the floating body out of a water body that is freezing over, and the ice pressure will thus be avoided. Advantageously an ice pressure is avoided and a lifetime as well as usability and efficiency are augmented. 
     Beyond this it is proposed that at least two side walls of the floating body are embodied at least partially as slant surfaces. Moreover it is possible for the underside of the floating body to be implemented as a slant surface. Preferably the slant surfaces are implemented at least partly in a curved manner. It is also conceivable that the slant surfaces are implemented at least partly in a planar fashion. Particularly preferably a main extension plane of a smallest imaginary rectangular cuboid which encloses the at least one side wall of the floating body includes an angle with a slant surface, in particular relative to the reference underside and/or the reference upper side of the floating body, that is in particular smaller than 88 degrees, preferably smaller than 85 degrees, preferably smaller than 82 degrees and especially preferentially smaller than 80 degrees. In particular, a main extension plane of a smallest imaginary rectangular cuboid enclosing the at least one side wall of the floating body includes an angle with a slant surface of in particular more than 45 degrees, preferentially more than 55 degrees, preferably more than 65 degrees and particularly preferably more than 70 degrees, in particular relative to the reference underside and/or the reference upper side of the floating body. It is possible for the slant surface, in particular side wall, to be implemented as a planar and/or curved and/or polygonal surface and/or as a combination thereof. Furthermore the slant surface, in particular side wall, could preferably be implemented of any number of sub-surfaces having any angles and/or curvatures relative to one another. In particular, the main extension plane of at least one side wall includes an angle of in particular less than 40 degrees, preferentially less than 30 degrees, preferably less than 20 degrees and especially preferentially less than 15 degrees with the reference side face of the floating body. The main extension plane of at least one side wall preferably includes an angle of in particular more than 1 degree, preferably more than 3 degrees, preferentially more than 4 degrees and particularly preferably more than 5 degrees with the reference side face of the floating body. This allows achieving a particularly advantageously flexible implementation of the invention, which is in particular usable independently from a frost risk. Furthermore in this way an efficiency and a lifetime of the invention are significantly augmentable as a destruction by ice, in particular ice pressure, is advantageously avoidable. 
     It is further proposed that at least two side walls of the floating body are arranged at least substantially in a wedge shape relative to one another. Preferably the side walls are implemented at least partially curved. The side walls could also be embodied in particular in a planar fashion. In particular, a first main extension plane of a smallest imaginary rectangular cuboid enclosing a first one of the side walls has an angle offset of in particular at least 4 degrees, preferably at least 16 degrees, preferentially at least 30 degrees, advantageously at least 45 degrees and particularly preferably at least 60 degrees relative to a second main extension plane of a smallest imaginary rectangular cuboid enclosing a second one of the side walls. 
     It is also proposed that at least one side wall of the floating body comprises at least one crimp profile, which is configured to augment a stability of the floating body. The crimp profile is in particular implemented integrally with the floating body. Preferentially the crimp profile is embodied as an elevation and/or deepening. Preferably the crimp profile is embodied as a groove-shaped and/or circle-shaped and/or ellipse-shaped deepening and/or elevation. Especially preferentially the crimp profile is arranged for a reinforcement and/or stiffening of at least one side wall of the floating body. It is in this way possible to save production costs by way of an advantageous shaping. In particular, there is an advantageous reduction of weight and/or of material costs due to shape-giving stiffening and/or design-based stability. 
     Beyond this it is proposed that the floating body comprises at least on an upper side and/or on an underside at least one crimp profile, which is configured to augment a stability of the floating body. The crimp profile is preferably arranged for a reinforcement and/or stiffening of the upper side and/or of the underside of the floating body. It is in this way possible to save production costs by way of an advantageous shaping. In particular, there is an advantageous reduction of weight and/or of material costs due to shape-giving stiffening and/or design-based stability. 
     It is furthermore proposed that the floating body comprises at least one closure element with a pressure compensation unit. The closure element is preferably configured for a checking and/or filling and/or emptying of the floating body. The pressure compensation unit is preferably configured to balance an inner pressure of the floating body with an ambient pressure, in particular in a bidirectional manner. Preferentially the pressure compensation unit is embodied as a pressure compensation valve. The pressure compensation unit may also be implemented as a breathable and/or flexible membrane. 
     Especially preferentially the pressure compensation unit is implemented to be water-impermeable, in particular impermeable for liquid water. This advantageously allows a flexible usage of the invention in a wide range of application areas, in particular with high temperature change rates. In this way a reduction of further tensions and/or forces is advantageously possible. Especially advantageously an efficiency regarding lifetime and production costs is thus increasable. 
     Furthermore it is proposed that the carrier structure comprises at least one carrier element that is embodied as a cable guiding unit, as a result of which a flexibly implementable installation can be made available. In particular, an advantageously secure and assembly-friendly cable guidance can be made available. Moreover, especially advantageously an assembly effort and/or installation efforts are/is reducible. The cable guiding unit is preferably implemented as a carrier element that is delimited at least on three sides. The cable guiding unit is furthermore in particular embodied as an empty conduit. 
     Preferentially the cable guiding unit may be implemented as a profiled semi-finished product. The cable guiding unit could also be implemented in particular as a cable guiding unit that is at least substantially closed, in particular along a circumference. The cable guiding unit is preferably implemented as an at least partially open cable guiding unit. 
     Preferentially the cable guiding unit comprises at least one edge protection element. For an accommodation of cables the cable guiding unit is in particular embodied as a U-profile and/or Z-profile and/or T-profile and/or L-profile and/or C-profile and/or is embodied of any profile combination. 
     It is also proposed that the carrier structure comprises at least one carrier element that is implemented by a hollow profile, as a result of which it is possible to provide an advantageously lightweight and stable carrier structure. In particular, an advantageously large lie-upon surface can be made available with a low weight. Preferentially the hollow profile is embodied as a tube-shaped rod profile. Preferably the hollow profile is embodied as a semi-finished product. Particularly preferably the hollow profile has a rectangular cross section. A polygonal and/or circular and/or square and/or elliptic and/or undulate cross section and/or a combination thereof are/is also conceivable. 
     It is also proposed that the carrier element is implemented at least partially open along a longitudinal axis, as a result of which a weight reduction is advantageously achievable. Preferably the carrier element is implemented at least substantially completely open along a longitudinal axis. The term “at least substantially completely” is here in particular to mean at least 55%, advantageously at least 65%, preferentially at least 75%, particularly preferably at least 85% and especially advantageously at least 95%. Preferably the carrier element is implemented to be at least substantially continuously open along a longitudinal axis. Particularly preferably the opening is implemented water-permeable. It is further conceivable that the opening may in particular be embodied as a membrane and/or as a lattice. 
     Furthermore it is proposed that in an assembled operation state the carrier element comprises at least one opening in a deepest point, which advantageously allows providing a drainage for water. In particular, the carrier element comprises, preferably in an assembled operation state, in a deepest point an opening towards the preferably ideal water surface and/or parallel to a reference surface normal of the reference underside of the floating body. It is also conceivable that in an assembled operation state the carrier element comprises, in particular in a deepest point, an opening in a horizontal direction. In particular, preferably in an assembled operation state, the carrier element comprises an opening that is oriented downwards, in particular in a direction that is parallel to a reference surface normal of the reference underside of the floating body. It is advantageously possible to prevent moisture retention and in particular an accompanying potential corrosive impact on the carrier element. 
     In an assembled operation state the carrier element is preferably arranged above the water surface. The opening of the carrier element is preferably oriented towards the water surface. Particularly preferably the opening is oriented in the direction of earth acceleration, in particular to allow a water exit out of the carrier element. Preferentially the opening is arranged in a deepest point of the carrier element, in particular towards the preferably ideal water surface. It is moreover conceivable that the opening is oriented at least substantially parallel to the water surface. 
     It is further proposed that the carrier element is implemented as a C-profile, which allows providing a high-grade production efficiency with low production costs. The C-profile is preferably implemented as a profiled semi-finished product. The C-profile is preferentially implemented as a rectangle profile. Particularly preferably the C-profile is enclosed at least on two sides and in particular comprises at least partially an opening on at least one side. 
     Beyond this it is proposed that in an assembled operation state, viewed in a direction from an upper side of the carrier element towards a water surface, the carrier element comprises at least one downwards-extending slant surface, as a result of which it is advantageously possible to improve a force flow and/or a force transmission. This advantageously results in an increased lifetime and/or in an advantageously broad flexible applicability of the invention. 
     The slant surface preferably has an angle offset relative to a surface of the carrier element that is implemented parallel to the, in particular ideal, water surface. In particular, the angle offset preferably has a value that is greater than 1 degree, preferentially greater than 2 degrees or particularly preferably greater than 5 degrees. The angle offset furthermore preferentially has a value that is smaller than 45 degrees, preferably smaller than 30 degrees or particularly preferably smaller than 15 degrees. Moreover the slant surface may in particular be implemented in a curved and/or planar fashion, and/or may be implemented as a combination of a curved and planar surface. Preferentially the slant surface of the carrier element is implemented to be at least partially correlating with the support surface of the floating body, in particular with the receiving contour. In particular, the slant surface of the carrier element, which is implemented correlating with the support surface, has an angle deviation of in particular less than 15 degrees, preferably less than 10 degrees, preferably less than 8 degrees and particularly preferably more than 2 degrees, preferably in a region that is provided for contacting. 
     It is also proposed that for a form-fit accommodation of the at least one floating body, the carrier structure comprises at least two carrier elements which are implemented as longitudinal carrier elements and at least one carrier element which is implemented as a transverse carrier element, as a result of which a flexible incorporation of the floating body in the installation according to the invention is achievable. Furthermore, especially advantageously an assembly time is reducible. Especially advantageously this allows dispensing with a usage of fixation means entering the floating body. Preferably, in an assembled operation state, the at least one carrier element implemented as a longitudinal carrier element is arranged along a longitudinal side of the floating body. The carrier elements implemented as longitudinal carrier elements are in particular arranged in the receiving regions of the side walls. Preferably the at least one carrier element implemented as a transverse carrier element is arranged on an upper side of the floating body. The at least one carrier element implemented as a transverse carrier element is in particular arranged in the receiving region of the upper side of the floating body. Preferentially the at least one carrier element implemented as a longitudinal carrier element and the at least one carrier element implemented as a transverse carrier element are arranged in such a way that in an assembled operation state, in particular on the water surface, a holding force can be exerted counter to a relative movement of the floating body and of the carrier structure in a horizontal and/or in a vertical direction. Preferably the at least one carrier element implemented as a longitudinal carrier element is in particular configured to exert a holding force counter to a vertical movement of the floating body relative to the carrier structure. 
     Beyond this it is proposed that the carrier structure is configured to receive at least one floating body such that it is supported floating, which allows an advantageous compensation of an, in particular temperature-induced, expansion and/or contraction of the floating body. 
     A floating support is preferably configured for receiving a unit and/or an element at least substantially without tension. In particular, a floating support preferably allows a movement range and/or expansion range of the received unit and/or element. 
     Preferentially the floating support provides a movement range and/or expansion range along at least one length that is greater than 1 mm, preferably greater than 2 mm and particularly preferably greater than 9 mm. Preferably the floating support furthermore provides a movement range and/or expansion range along at least one length that is smaller than 15 mm, preferentially smaller than 7 mm and especially preferentially smaller than 4 mm. A floating support is in particular configured for receiving and/or supporting a supported unit in at least one direction by way of a clearance fit. 
     It is thus particularly preferably possible to achieve a high level of flexibility regarding a location of use of the installation according to the invention, in particular a location of use with a great range of temperature fluctuations. 
     Moreover it is proposed that the carrier structure has a maximum longitudinal extension of at least 4 m, preferably at least 6 m, preferentially at least 8 m and particularly preferably at least 9 m. An advantageously large energy conversion area can be facilitated. An advantageously stable and robust implementation of the floating carrier device is achievable. The maximum longitudinal extension of the carrier structure is preferably oriented at least substantially parallel to the main extension plane of the floating carrier device, in particular of the carrier structure, and/or is oriented, in particular in a floating state of the floating carrier device, at least substantially parallel to the ideal water surface. Preferentially, viewed in at least one plane, in particular a plane that is oriented at least substantially parallel to the main extension plane of the floating carrier device, in particular the carrier structure, and/or is oriented, in particular in a floating state of the floating carrier device, at least substantially parallel to the ideal water surface, the floating carrier device, in particular the carrier structure, has an at least substantially rectangular basic shape, wherein in particular the maximum longitudinal extension of the carrier structure extends along a longest side of the basic shape.

The connection element is in particular fixated to the anchoring element on one end of the connection element and is fixated to the floating body and/or to the carrier structure with another end of the connection element that is situated opposite the end. Particularly preferably the anchoring unit, in particular the connection element, is arranged and/or implemented in such a way that the floating carrier device is movable relative to an anchoring position on the ground of the water body, in which in particular the anchoring element is arranged, by at least 1 m, preferably by at least 3 m and preferentially by at least 5 m, preferably without a full tensioning of the connection element, in particular for the purpose of following a swell and/or wind waves. Preferably the connection element is fixated to the floating body and/or to the carrier structure in an at least substantially non-releasable manner, by substance-to-substance bond and/or by a screw or clamp connection. A “substantially non-releasable manner” is in particular meant to describe a connection of at least two components, in particular the connection element and the floating body and/or the carrier structure, which are only separable from each other by using separating tools, like for example a saw, in particular a mechanical saw, etc, and/or by using chemical separation means, like for example solvents etc. 
     Furthermore a floating body, in particular the above-mentioned floating body, of a floating carrier device according to the invention, in particular the above-mentioned floating carrier device, is proposed, as a result of which a solar device can be made available that is implementable in a particularly advantageous manner.

     Furthermore a carrier structure is proposed that has a roof structure which is configured to provide assembly surfaces for receiving at least one solar element, as a result of which a solar device can be made available that is implementable in a particularly advantageous manner. Preferably the roof structure may be implemented as a saddle roof structure. Preferentially the roof structure may be implemented as a single-pitch roof structure and/or as a flat roof structure. Preferably the saddle roof structure may also be configured for an east-west orientation, in particular of the assembly surfaces. Furthermore the single-pitch roof structure may preferably be implemented for an orientation to the south, in particular of the assembly surfaces. 
     Furthermore a solar device is proposed, with a floating carrier device, in particular the above-mentioned floating carrier device, and with at least one solar element, as a result of which a solar device can be made available that is implementable in a particularly advantageous manner. Preferably, by a “solar element” an element may be understood that is implemented for a conversion of a solar radiation energy. The solar element is preferably embodied as a conversion unit for a conversion of a solar radiation energy into thermal energy, in particular for heating a heat exchanger medium. Particularly preferably the solar element is embodied as a photovoltaic cell and/or as a photovoltaic module, which is configured for a conversion of a solar radiation energy into electrical energy. 
     It is further proposed that the solar device comprises a roof structure that is implemented to accommodate at least two solar elements such that they are directly adjacent to each other, wherein in an assembled operation state the solar elements form an air circulation opening in a highest point. In this way, a passive cooling effect, in particular a chimney effect, is particularly advantageously achievable. Furthermore this allows providing an installation which is advantageously flexibly usable and which is especially advantageously capable of providing a cooling effect that is independent from environmental influences. Preferably a point that is the highest in a vertical direction, in particular a point that is the farthest away from the water surface, is realized as the highest point. 
     The air circulation opening is in particular arranged in a roof ridge region of the roof structure. The roof ridge region is preferably implemented as an interruption-free opening, preferentially as a continuous opening. It is further conceivable that the air circulation opening is in particular formed of at least two or of a plurality of openings. Preferably the air circulation opening is implemented in the roof ridge region as a spacing between directly adjacent solar elements, which in particular face away from each other, and is implemented larger than 5 mm, advantageously larger than 10 mm, preferably larger than 15 mm, particularly preferably larger than 20 mm and especially advantageously larger than 25 mm.

In particular, the air circulation opening between the spaced-apart solar elements is at least largely free of structural components. Preferentially the air circulation opening between the spaced-apart solar elements is completely free of structural components. Preferably the air circulation opening is configured to permit an exit of an ascending air flow, which in particular ascends due to heating up, preferably an exit out of the roof structure. The air circulation opening is in particular configured for an outward conveyance of a vertical airflow, which is in particular due to convection, preferably a conveyance out of the roof structure. 
     Preferentially the two directly adjacent solar elements are arranged facing away from each other. Particularly preferably the two directly adjacent solar elements are arranged on differing saddle roof side faces. 
     It is also proposed that the solar device comprises a plurality of solar elements, in particular more than twelve solar elements, which, in particular in an arrangement on the floating carrier device, together have a maximum longitudinal extension of at least 4 m, preferably at least 6 m, preferentially at least 8 m and especially preferentially at least 9 m. It is possible to facilitate an advantageously large energy conversion area of the solar device. An advantageously high energy efficiency and/or an advantageously high generated power output of the solar device are/is achievable. Advantageously low assembly and maintenance costs can be made possible, in particular as on average an advantageously low number of solar devices can be used for producing a given power output that is to be generated. It is in particular conceivable that the solar device comprises only one solar element having a maximum longitudinal extension of at least 4 m, preferably at least 6 m, preferentially at least 8 m and particularly preferably at least 9 m. In an assembled state of the solar device and/or in a state of the solar elements being arranged on the carrier structure, the maximum longitudinal extension of the solar elements is preferably oriented at least substantially parallel to the maximum longitudinal extension of the carrier structure, in particular the bracing element, and/or of the floating carrier device, in particular the main extension plane of the floating carrier device. Preferably the solar elements, in a state when arranged on the carrier structure, are arranged along the maximum longitudinal extension of the solar elements in two rows, which are in particular arranged at least substantially parallel to each other. Especially preferentially the maximum longitudinal extension of the solar elements is to mean the maximum longitudinal extension of all solar elements in a state when arranged on the carrier structure, and is in particular realized differently from a maximum longitudinal extension of the individual solar elements. Preferably, in the assembled state of the solar device and/or in the state of the solar elements being arranged on the carrier structure, the carrier structure, in particular the at least one bracing element, extends at least to a major part, in particular at least substantially completely, over the maximum longitudinal extension of the solar elements, in particular with the solar elements, in particular a row of the solar elements, being arranged, in particular fixated, on the bracing element.

The floating carrier device  8  comprises four floating bodies  12 . Furthermore the floating carrier device  8  comprises the carrier structure  14  that is coupled with the floating bodies  12 . It is further conceivable for the floating carrier device  8  to comprise a greater or a smaller number of floating bodies  12 . For example, the floating carrier device  8  could comprise two or three or five floating bodies  12 . It is also conceivable that the floating carrier device  8  accommodates a greater or a smaller number of solar elements  10 . For example, the floating carrier device  8  could accommodate two or eight or fourteen solar elements  10 . 
     The floating carrier device  8  is configured to support an energy conversion unit  52  floating on a water body, the energy conversion unit  52  comprising twelve photovoltaic modules that are embodied as solar elements  10 . Principally the energy conversion unit  52  preferably comprises eighteen photovoltaic modules that are embodied as solar elements  10 . The solar elements  10  are realized as photovoltaic modules. The photovoltaic modules are configured for a conversion of solar radiation energy into electrical current. The floating carrier device  8  implements a floating unit  48   a  with four floating bodies  12 . 
     Furthermore, the floating carrier device  8  with the carrier structure  14  is configured to transfer a support force of the twelve solar elements  10  to the four floating bodies  12 . 
     Moreover, a carrier structure  14   a  is configured to transfer a support force from a power converter device  50  to two floating bodies  14  (see  FIG. 3 ). The power converter device  50  is embodied as a power inverter. The power inverter is configured to change a direct current generated by the solar elements  10  of several floating units  48   b  into an alternating current. The power inverter is realized with a power output of 40 VA. A maximum input voltage of the power inverter is 1100 V DC. An output voltage of the power inverter is 400 V AC. 
     The floating carrier device  8 ,  9 , in particular the floating carrier device  8 ,  9  shown in  FIG. 2  and/or a floating carrier device  8 ,  9  shown in  FIG. 3 , preferably comprises a plurality of bottom elements  96 , which are arranged on the carrier structure  14 . The bottom elements  96  are configured, in particular together with the floating bodies  12 , to form a walkable surface of the floating carrier device  8 ,  9 . The bottom elements  96  are in particular embodied as step plates. Other implementations of the bottom elements  96  are also conceivable. Preferentially the bottom elements  96  are configured to be arranged between the floating bodies  12 . Preferably the bottom elements  96  are fixated on the carrier structure  14 . For example, the bottom elements  96  each comprise, on at least two sides facing away from each other, respective receptacles which are configured for a fixation on a carrier element  36  and/or on a bracing element  108  of the carrier structure  14 . In particular, the bottom elements  96  lie upon the carrier structure  14  via the receptacles. 
     The bottom elements  96  are preferably embodied at least substantially in the shape of panels. Preferably the bottom elements  96  delimit a plurality of pass-throughs, in particular such that they are distributed over a main extension plane of the bottom elements  96  (not shown in  FIG. 2 ; see  FIGS. 3, 13 and 14 ). In a state when the bottom elements  96  are fixated, in particular mounted, on the carrier structure  14 , the pass-throughs extend from an upper side of the bottom elements  96  over an entire height of the bottom elements  96  to an underside of the bottom elements  96 . The pass-throughs are preferably configured for conveying water through the bottom elements  96  from the upper side of the bottom elements  96  in a perpendicular direction. The pass-throughs are preferentially configured to at least substantially prevent a retention of water on the bottom elements  96 . The bottom elements  96  are preferably embodied at least partly in an anti-skid fashion, in particular on an upper side of the bottom elements  96 . In a preferred implementation the bottom elements  96  form edgings delimiting the pass-throughs (not shown in the figures) and having an anti-skid effect. For example, the pass-throughs are embodied in a round or in an angular manner.

     Each floating body  12  comprises on two side walls  16  a receiving region  20  for the carrier structure  14 ,  14   a . The side wall  16 ,  18  of the floating body  12  is a wall of the floating body  12  whose envelope section faces toward a reference side face  62 ,  64  of a smallest imaginary reference rectangular cuboid  54 , the reference rectangular cuboid  54  just still completely enclosing the floating body  12  (see  FIG. 5 a , 5 b   ). Preferably an envelope  56  is a geometrically smallest free geometry enveloping a body. The envelope  56  is free of inflection points.

The receiving contour is configured for a delimitation of the receiving region  20 . The receiving region  20  is furthermore implemented as a deepening. The deepening is implemented as a combination of a U-shape and a V-shape, the flanks of the U-shape being formed in a V-shape. The receiving region  20  on the side wall  16  has a cross section increasing in the direction of the reference surface normal of the allocated reference side face  62 . The receiving region  20  has a smallest cross section in a deepest point in the floating body  12 . Starting from the deepest point of the receiving region  20  in the floating body  12 , the cross section of the receiving region  20  increases in the direction of a reference surface normal. 
     The floating body  12  further comprises on its upper side  24  a further receiving region  22  for the carrier structure  14 ,  14   a , which is also shown in  FIG. 4 . The upper side  24  has a curved surface. The curved upper side  24  of the floating body  12  is implemented in a convex fashion. As a result of this, in particular a stability of the floating body  12  is advantageously augmented. In an assembled operation state the upper side  24  of the floating body  12  is arranged above the ideal water surface  82  and is furthermore spaced apart from the ideal water surface  82 . 
     The further receiving region  22  is arranged on the upper side  24  of the floating body  12 . The further receiving region  22  provides for the carrier structure  14 ,  14   a  a support surface for a support of support forces. The further receiving region  22  comprises a receiving contour. The receiving contour is configured for a delimitation of the further receiving region  22 . The further receiving region  22  is furthermore implemented as a deepening. The deepening is implemented as a combination of a U-shape and a V-shape, the flanks of the U-shape being formed in a V-shape.

Starting from the deepest point of the further receiving region  22  in the floating body  12 , the cross section of the further receiving region  22  increases parallel to a direction of the reference surface normal. In a valley bottom of the further receiving region  22  a contour is realized for receiving a carrier element  44  that is embodied as a transverse carrier element. The contour is realized to be correlating with a contour of the hollow profile of the carrier element  44  embodied as a transverse carrier element. The contour is implemented for a centering of the carrier element  44  embodied as a transverse carrier element in the further receiving region  22  (see  FIG. 4 ). 
     Furthermore the receiving region  20  and the further receiving region  22  are embodied integrally with the floating body  12 .

The receiving region  20  and the further receiving region  22  have a material thickness of up to 10 mm. Other regions have a minimum material thickness of up to 2 mm. Due to the increased material thickness in the receiving region  20  and the further receiving region  22 , a temperature-dependent expansion or contraction of the floating body  12  is advantageously realized rather in regions having a comparably smaller material thickness. The floating body  12  has a deepening that implements the receiving region  20  and the further receiving region  22 . The receiving region  20  and the further receiving region  22  and the floating body  12  are formed from one piece.

The support surfaces of the receiving region  20  and of the further receiving region  22  are configured to transfer support forces from the carrier structure  14 ,  14   a  to the floating body  12  via the form-fit accommodation. In an assembled operation state the support surfaces are partially spaced apart from the carrier structure  14 ,  14   a . The form-fit accommodation of the carrier structure  14 ,  14   a  permits, in an assembled operation state, a movement range to the floating body  12 .

A middle axis through center points of the reference upper side  58  and the reference underside  60  is perpendicular both to the reference upper side  58  and to the reference underside  60 . 
     The stack elements  26 , with respect to the center point of the reference upper side  58 , are arranged to be correlating with the stack elements  28 , with respect to the center point of the reference underside  60 . 
     In a projection of the arrangement of the stack elements  26  onto the reference upper side  58  and a projection of the arrangement of the stack elements  28  onto the reference underside  60 , the stack elements  26 ,  28  are arranged to be correlating relative to the shared middle axis of the reference upper side  58  and the reference underside  60 .

     Furthermore, in an operation state when floating and assembled, the floating body  12  is arranged at least partially above the water surface  82 . In a state when floating and assembled, the floating body  12  receives the carrier structure  14 ,  14   a  of the floating carrier device. In a state when floating and assembled, the upper side  24  of the floating body  12  is situated above the water surface  82 .

The floating body  12  has a decreasing maximum transverse extension in the direction of the reference surface normal of the reference underside  60 . The maximum transverse extension of the floating body  12  decreases by approximately 19 cm relative to the maximum transverse extension of the underside  32  of the floating body  12 . 
     The floating body  12  further comprises four side walls  16 ,  18 , which are embodied at least partially as slant surfaces. The side walls  16 ,  18  of the floating body  12  are embodied differently than the upper side  24  and the underside  32  of the floating body  12 . The side walls  16 ,  18  connect the upper side  24  and the underside  32  of the floating body  12  to one another. The side walls  16 ,  18  have a curved surface. The side walls  16 ,  18  furthermore have a surface that is at least partially convexly curved. Main extension planes of the side wall  16 ,  18  form an angle of approximately 10 degrees relative to an allocated reference side face  62 ,  64  of the floating body  12 . In an assembled operation state, the main extension planes of the side walls  16 ,  18  furthermore have an angle of approximately 80 degrees relative to the ideal water surface  82 . 
     The four side walls  16 ,  18  of the floating body  12  are arranged at least substantially in a wedge-shaped fashion to each other. The side walls  16 ,  18  are embodied to be at least partially curved. Moreover a first main extension plane of a smallest imaginary rectangular cuboid enclosing a first one of the side walls  16 ,  18  has an angle offset of approximately 20 degrees relative to a second main extension plane of a smallest imaginary rectangular cuboid enclosing a second one of the side walls  16 ,  18 . It is principally also conceivable for the angle offset to be realized smaller or greater. The angle offset may in particular be realized to be greater than 4 degrees and preferably smaller than 40 degrees.

The two other floating bodies  12  are free of an overlap by solar elements  10 . The two other floating bodies  12  are furthermore implemented as a walkway. In a region between the two other floating bodies  12  and between the carrier elements  42  that are embodied as longitudinal carrier elements, two panels are arranged. The panels are configured to form a walkway. The panels are mounted above the carrier elements  42  that are embodied as longitudinal carrier elements. 
     The carrier structure  14   a , which is configured to accommodate the power converter device  50 , comprises four carrier elements  42  embodied as longitudinal carrier elements, wherein respectively two of the carrier elements  42  embodied as longitudinal carrier elements are configured to accommodate respectively one of the floating bodies  12  in a form-fit, floating fashion. The carrier elements  42  that are embodied as longitudinal carrier elements and are arranged in pairs are connected by means of three carrier elements  44  embodied as transverse carrier elements. Two U profiles are arranged parallel to the carrier elements  42  that are embodied as longitudinal carrier elements and below the carrier elements  44  that are embodied as transverse carrier elements, and are connected to the carrier elements  44  that are embodied as transverse carrier elements. The power converter device  50  is arranged on the carrier structure  14   a , centrally between the two floating bodies  12 . On the carrier structure  14   a  separate cable guiding units for AC and DC lines are arranged next to the power converter device  50 . Furthermore gratings are arranged on the carrier structure  14   a  which form a walkway, in particular by the further alleyways  92 . 
     The carrier structure  14 ,  14   a  is also configured to receive at least one floating body  12  such that it is supported in a floating fashion (see  FIG. 8 ). The floating support of the floating body  12  in the carrier structure  14 ,  14   a  permits a movement range and/or expansion range of the floating body  12  that is delimited by the receiving region  20  and the further receiving region  22 . The floating body  12  being received in the carrier structure  14 ,  14   a  is brought about without additional connection means. This especially advantageously allows doing without making use of fixation means entering the floating body  12 . The receiving contours of the receiving region  20  and of the further receiving region  22  are configured for a centering receiving of the floating body  12 . In an assembled operation state, the carrier elements  42  embodied as longitudinal carrier elements and the carrier elements  44  embodied as transverse carrier elements delimit an at least substantially perpendicular movement of the floating body  12  relative to the ideal water surface  82 .

     The carrier structure  14  is furthermore implemented as a roof structure (see  FIGS. 2 and 7 ). The roof structure comprises mounting surfaces which are configured to receive twelve solar elements  10 . The roof structure is particularly preferably implemented for an accommodation of eighteen solar elements  10 . The roof structure is furthermore embodied as a saddle roof structure. The purlin elements span the mounting surface together with the carrier elements  36 . The solar elements  10  are arranged on an upper side of the purlin elements.

     Furthermore a solar device comprises the floating carrier device  8  with twelve solar elements  10 . The solar device has a saddle roof structure configured to receive six solar elements  10  on each side of the saddle roof structure. In an assembled operation state respectively two directly neighboring solar elements  10 , each of the two solar elements  10  being arranged on its own saddle roof side, form an air circulation opening  46  in a highest point. The air circulation opening  46  is arranged in a roof ridge region of the roof structure. The roof ridge region is implemented as an interruption-free continuous opening. The air circulation opening  46  is embodied as a spacing in the roof ridge region between directly neighboring solar elements  10  which are arranged facing away from one another. The spacing is 26 mm. The air circulation opening  46  between the spaced-apart solar elements  10  is completely free of structural components. The air circulation opening  46  is configured for conveying away a vertical air flow that is due to convection, preferably from the roof structure. 
     The energy conversion system  6  further comprises a connection device  66 . The connection device  66  connects nine floating units  48   a , which are embodied as a floating carrier device in a rigid manner to form a raft unit  68 , and connects a plurality of raft units  68  to one another in a movable manner.

     The carrier elements  42  embodied as longitudinal carrier elements and the carrier elements  44  embodied as transverse carrier elements have a connection region on both front regions. The connection region is configured for an accommodation of a connection device  66 . The connection region further comprises a fixation means receiving region for an accommodation of fixation means. The fixation means receiving region has two round openings on each front side. 
     The raft unit  68  is furthermore embodied as a 3×3 array with nine rigidly connected floating units  48   a  (see  FIGS. 1 a  and 1 b   ). It is moreover conceivable for the raft unit  68  to be implemented of more or less than nine floating units  48   a . It is also conceivable for the floating units  48   a  to be connected to one another in a partly movable manner. The floating units  48   a  are arranged in a rectangle array.

     The connection device  66  partially has a connection with the carrier structure  14 ,  14   a . In an assembled operation state the connection device  66  is arranged on the open front sides of the carrier elements  42  that are embodied as longitudinal carrier elements and of the carrier elements  44  that are embodied as transverse carrier elements. The connection device  66  is configured to be connected, partly via screw connections and partly via rivet connections, to the carrier elements  42  embodied as longitudinal carrier elements and to the carrier elements  44  embodied as transverse carrier elements. 
     In a pre-assembled state the connection device  66  comprises at least one connection unit that is embodied as a foldable connection unit. The connection device  66  is in the pre-assembled state configured to be connected, by one of two provided screw connections, to the connection region of the carrier element  42  that is embodied as a longitudinal carrier element or of the carrier element  44  that is embodied as a transverse carrier element. The carrier element  42  that is embodied as a longitudinal carrier element and the carrier element  44  that is embodied as a transverse carrier element each comprise respectively one receiving opening on their front sides, which is implemented to be correlating with a width of the connection device  66 . In this way it is possible, in a pre-assembled state, for the connection device  66  to be folded on a partial circle around an axle of the one mounted screw connection. The receiving opening is configured to receive a longitudinal axle of the connection device  66  in an at least substantially perpendicular position. The foldable connection device  66  is configured to be folded from a pre-assembled state into an assembled operation state.

     Beyond this the connection device  66  comprises at least one damper unit  70 . In an assembled operation state the damper unit  70  is realized between the connection device  66  and a connection region of one of the carrier elements  42  embodied as longitudinal carrier elements or of the carrier elements  44  embodied as transverse carrier elements. The damper unit  70  is embodied as a spring-elastic element. The damper unit  70  is furthermore embodied as a macroscopic element. The damper unit  70  has at least one extension that is elastically modifiable by 10% in an assembled operation state. The damper unit  70  furthermore generates a counterforce acting counter to the modification, which is dependent on the modification of the extension, and is preferably proportional to the modification. The damper unit  70  further comprises a rubber damper element. The damper unit  70  has a rectangle geometry. 
     The connection device  66  further comprises a movable connection unit  72  (see  FIG. 9 ). In an assembled operation state the movable connection unit  72  comprises two connection elements  74 ,  76 , which are connected with each other in a pivotable manner. The connection elements  74 ,  76  share a pivot axis. The pivot axis is implemented by a threaded bolt. The bolt is furthermore embodied as a plug bolt. The connection elements  74 ,  76  further comprise respectively two pass-through openings for connection means. The connection means is embodied as a plug bolt having a securing element. 
     Beyond this the connection device  66  comprises a hollow profile. The hollow profile of the connection device  66  has, in at least one front region, a reduced cross section, in particular relative to the cross section of the hollow profile. In a pre-assembled state of the connection device  66 , the reduced cross section in the front region is configured for folding off, without resistance, at least one portion of the connection device  66  into the corresponding receiving opening on the carrier element  42  that is embodied as a longitudinal carrier element or on the carrier element  44  that is embodied as a transverse carrier element. Starting from the front region of the hollow profile, the reduced cross section has an at least substantially wedge-shaped profile, which is implemented with a step in a longitudinal direction of the hollow profile. Furthermore end regions of the wedge-shaped profile are embodied in a rounded manner. 
     The first connection element  74  is implemented as a rectangular hollow profile with a support opening along a longitudinal axis. The hollow profile is implemented in a square shape with an edge length of 40 mm×40 mm. The support opening is configured to movably receive the second connection element  76 . The support opening is realized as a recess along a longitudinal axis of the hollow profile. The recess extends through two side faces of the hollow profile which extend at least substantially parallel to each other. The first connection element  74  and the second connection element  76  are configured to be received on the open front region of the carrier element  42  that is embodied as a longitudinal carrier element or of the carrier element  44  that is embodied as a transverse carrier element. The second connection element  76  is realized as a combination of a flat material and a hollow profile. The hollow profiles of the first and second connection elements  74 ,  76  each have respectively two pass-through openings in the connection regions, for the purpose of receiving connection means. The connection means are embodied as plug bolts respectively having a securing element. The flat material is implemented such that it is welded with the one hollow profile of the second connection element  76 . In an assembled operation state the flat material of the second connection element  76  is configured such that it is received in the receiving opening of the first connection element  74  and is movable around the shared pivot axis. The flat material of the second connection element  76  has a radius in a front region. The radius is configured such that the second connection element  76  is implemented to be pivotable without resistance in the receiving opening of the first connection element  74 . In an assembled operation state the movable connection unit  72  is configured to permit a pivot movement in a plane that is perpendicular to the ideal water surface  82 . It is furthermore possible for the movable connection unit  72  to be implemented in such a way that it is movably supported in the connection region via the connection means. 
     Further a rigid connection unit  78  is implemented by a hollow profile (see  FIG. 10 ). The hollow profile has the measurements 40 mm×40 mm. The rigid connection unit  78  comprises in total four pass-through openings for connection means. It is also conceivable that the rigid connection unit  78  comprises a plurality of pass-through openings. The connection means are embodied as plug bolts having a securing element. The hollow profile of the rigid connection unit  78  has a reduced cross section in both front regions. The reduced cross section is realized perpendicularly to the longitudinal axis of the rigid connection unit  78 . Starting from the front region of the hollow profile, the reduced cross section has an at least substantially wedge-shaped profile, which is implemented with a step in the longitudinal direction of the hollow profile. Furthermore the end regions of the hollow profile are embodied in a rounded manner. 
     Furthermore the connection device  66 , with the exception of the damper unit  70 , is embodied entirely of steel. 
     Beyond this, from a length of approximately 130 m, an array of raft units  68  is encompassed by a wave-breaker device  80  of the energy conversion system  6  (see also  FIG. 11 ). The wave-breaker device  80  is implemented as a plurality of floating bodies  12 , which are connected via longitudinal carrier elements  42  and movable connection units  72 . In an assembled operation state, as part of the wave-breaker device  80 , the floating bodies  12  have water as ballast inside their hollow spaces. The wave-breaker device  80  further comprises a movable connection with the raft units  68 . In an assembled operation state the wave-breaker device  80  is connected to the raft units  68  of the energy conversion system  6  by way of movable connection units  72  (see  FIG. 1 ). It is conceivable for the energy conversion system  6 , in particular the floating carrier devices  8 ,  9  and/or the floating units  48   a ,  48   b , to comprise at least one bird-deterrent unit that is configured to prevent birds from nesting and/or from stopping on the energy conversion system  6 .

It is also conceivable that the bird-deterrent unit is arranged at least partially on the wave-breaker device  80 . 
     The arrangement of the energy conversion system  6  moreover comprises, following a sequence of twelve row-wise adjacent floating carrier devices  8  loaded with solar elements  10 , a further floating carrier device  9  with the power converter device  50 , followed by another sequence of twelve row-wise adjacent floating carrier devices  8  loaded with solar elements  10  (see  FIG. 2 ). The floating carrier devices  9  with the respectively one power converter device  50  form, in particular by the further alleyways  92 , a walkway that is perpendicular to the walkways, which are in particular formed by the alleyways  88 , of the floating carrier devices  8  with the solar elements  10 . 
       FIG. 11  shows a portion of an energy conversion system  122  with a stabilization device  116 . The stabilization device  116  is arranged on a floating unit  118  of the energy conversion system  122  below an, in particular ideal, water surface  82  of the water body. The stabilization device  116  is configured to apply, at least onto the floating unit  118 , a counterforce to a movement of the floating unit  118  relative to the water surface  82  wherein, in at least one operation state, the stabilization device  116  has a greater maximum distance  120  from the, in particular ideal, water surface  82  than the floating unit  118 , in particular than a floating body  102  of the floating unit  118 . The stabilization device  116  is fixated, in particular at least substantially non-releasably, in particular via a rivet connection, on a floating body  102  of the floating unit  118 , on the connection device  66  and/or on a carrier structure  104  of the energy conversion system  122 . It is also conceivable that the stabilization device  116  is fixated on the floating body  102  of the floating unit  118 , on the connection device  66  and/or on the carrier structure  104  via a screw connection or the like. 
     The stabilization device  116  comprises a plurality of, in particular three, stabilization elements  124  for a cooperation with a fluid of the water body, and comprises at least one bracing unit  126  for an, in particular at least substantially tolerance-free, arrangement of the stabilization elements  124 . The stabilization elements  124  are arranged on an underside of the energy conversion system  122 , in particular of the floating unit  118 . In particular in a floating state of the energy conversion system  122 , in particular of the floating unit  118 , the stabilization elements  124  are arranged below the water surface  82 . The bracing unit  126  comprises a plurality of bracing elements  128 , which connect the stabilization elements  124  with the floating body  102  of the floating unit  118 , with the connection device  66  and/or with the carrier structure  104 . The stabilization elements  124  are arranged at least substantially parallel to the, in particular ideal, water surface  82 . In particular, a main extension axis of the stabilization elements  124  extends at least substantially parallel to the, in particular ideal, water surface  82 . The stabilization device  116  comprises two further stabilization elements  130 , which are respectively arranged on the bracing elements  128 . In particular, the further stabilization elements  130  extend between two bracing elements  128  of the bracing unit  126 , which in particular extend at least substantially perpendicularly to the water surface  82 . 
     The stabilization device  116 , in particular the stabilization elements  124 , comprises/comprise force transfer areas  132  for a cooperation with a fluid of the water body which, in particular in at least one operation state, are arranged, at least to a large extent, at least substantially parallel to an ideal water surface  82 . 
     The stabilization device  116 , in particular the further stabilization elements  130 , comprises transverse force transfer areas  134  for a cooperation with a fluid of the water body which, in particular in at least one operation state, are arranged, at least to a large extent, at least substantially perpendicularly to an ideal water surface  82 . The stabilization elements  124  form the force transfer areas  132 . The further stabilization elements  130  form the transverse force transfer areas  134 . The stabilization elements  124  are each embodied at least substantially panel-shaped. The further stabilization elements  130  are each embodied at least substantially panel-shaped. The stabilization elements  124  respectively form two force transfer areas  132 , which are arranged on sides of the respective stabilization element  124  that face away from each other. The further stabilization elements  130  respectively form two transverse force transfer areas  134 , which are arranged on sides of the respective further stabilization element  130  that face away from each other. The force transfer areas  132  and/or the transverse force transfer areas  134  are respectively embodied having at least largely planar surfaces. One of the stabilization elements  124  is arranged, in particular viewed along a direction that is oriented at least substantially perpendicularly to the water surface  82 , between the two further stabilization elements  130  and/or between the bracing elements  128 . Two other stabilization elements  124  are respectively arranged on one of the further stabilization elements  130  and/or on two of the bracing elements  128 . The two other stabilization elements  124  in particular form projections respectively extending away from the bracing unit  126 , in particular the bracing elements  128 . The stabilization elements  124  are embodied as panels, which are connected to one another via a strut system. The bracing elements  128  of the bracing unit  126  are embodied as rod-shaped struts, which in particular the stabilization elements  124  and the further stabilization elements  130  are fixated to. Preferentially the stabilization elements  124  and/or the further stabilization elements  130  are fixated on the carrier structure  104  of the floating unit  118  by means of the bracing unit  126 , in particular the bracing elements  128 . The bracing unit  126  comprises, in particular four, further bracing elements  136 , which in particular support the bracing elements  128  against a movement towards each other, in a direction that is oriented at least substantially parallel to the water surface  82 . The further bracing elements  136  are arranged respectively cross-wise with another further bracing element  136 . In particular, respectively two of the bracing elements  128  are implemented integrally with one of the further stabilization elements  130 . It is however also conceivable that the bracing elements  128  and the further stabilization elements  130  are implemented separately and/or are arranged, in particular fixated, to each other. Preferably the cross-wise arranged further bracing elements  136  are fixated to each other and/or supported rotatably to each other in a contact region, in particular a middle region that is arranged around a geometrical center of the further bracing element  136 . Preferentially each of the further bracing elements  136  is arranged with one end on one of the bracing elements  128 . It is however also conceivable that the further bracing elements  136  are arranged with one end on the carrier structure  104 . It is also conceivable for the stabilization device  116 , in particular the bracing unit  126 , to be arranged, in particular fixated, on a wave-breaker device  80  of the energy conversion system  122 , which is in particular arranged on the floating unit  118  and/or on the carrier structure  104 . However, other implementations of the stabilization device  116 , in particular of the stabilization elements  124 , the further stabilization elements  130  and/or the bracing unit  126 , are also conceivable. 
     In at least one operation state the stabilization device  116  has in a perpendicular direction a maximum distance  138  from the floating unit  118  that is at least 50 cm, preferably at least 100 cm, preferentially at least 150 cm and particularly preferably at least 180 cm. In particular, the maximum distance  138  of the stabilization device  116 , in particular the stabilization elements  124 , from the floating unit  118  is maximally 400 cm, preferably no more than 300 cm and preferentially no more than 250 cm. The maximum distance  138  of the stabilization device  116 , in particular the stabilization elements  124 , from the floating unit  118  extends at least substantially perpendicularly to the ideal water surface  82 . In particular, a minimum distance  140  of the stabilization device  116 , in particular the stabilization elements  124 , from the floating unit  118 , in particular from an underside and/or a bottom of the floating unit  118 , in particular from a floating body  102  of the floating unit  118 , is at least 40 cm, preferentially at least 80 cm, preferably at least 120 cm and particularly preferably at least 160 cm. The bracing elements  128  of the bracing unit  126 , in particular at least one of the bracing elements  128  of the bracing unit  126 , preferably have/has a maximum longitudinal extension  142  of at least 150 cm, preferentially at least 170 cm and especially preferentially at least 190 cm. The bracing elements  128  of the bracing unit  126  are preferably arranged, in particular fixated, with one end on the connection device  66  and/or on the carrier structure  104 . The bracing elements  128  of the bracing unit  126  are preferably arranged, in particular fixated, with another end that faces away from the one end, on one of the stabilization elements  124 . 
     The force transfer areas  132 , in particular a total of all force transfer areas  132  of the stabilization elements  124 , are at least 2,500 cm 2 , preferably at least 5,000 cm 2 , preferentially at least 7,500 cm 2  and especially preferentially at least 10.000 cm 2 . The transverse force transfer areas  134 , in particular a total of all transverse force transfer areas  134  of the further stabilization elements  130 , are at least 1,000 cm 2 , preferentially at least 2,000 cm 2  and preferably at least 3,000 cm 2 . In particular, the force transfer areas  132 , in particular the total of all force transfer areas  132  of the stabilization elements  124 , are maximally 30,000 cm 2 , preferentially no more than 25,000 cm 2  and preferably maximally 20,000 cm 2 . Main extension planes of the individual force transfer areas  132  respectively extend at least substantially parallel to the ideal water surface  82 . In particular, the stabilization elements  124  each comprise a further force transfer area  132 , which is in particular arranged on a side of the stabilization element  124  that faces away from a force transfer area  132 . Particularly preferably the force transfer area  132  is arranged on a side of the stabilization device  116 , in particular the stabilization element  124 , that faces towards the ideal water surface  82 . Preferably the further force transfer area  132  is arranged on a side of the stabilization device  116 , in particular the stabilization element  124 , that faces away from the ideal water surface  82 . Preferentially the force transfer area  132  and the further force transfer area  132  are embodied to be congruent. It is however also conceivable that the force transfer area  132  and the further force transfer area  132  are embodied differently. A main extension plane of the further force transfer area  132  preferentially extends at least substantially parallel to the ideal water surface  82 . It is conceivable for the stabilization device  116  to comprise a plurality of stabilization elements  124 , which in particular together form a force transfer area  132  and a further force transfer area  132 . A size of the force transfer area  132  and/or the further force transfer area  132  is implemented to be adjustable, in particular by a modular removal or addition of individual stabilization elements  124 . For example, the counterforce acting onto the floating unit  118  may be adapted via the force transfer areas  132  in an application-specific and/or environment-specific manner, depending on a weight of the energy conversion system  122 , in particular of the floating unit  118 , and/or on a swell/on wind waves of the water body. 
     In  FIGS. 12 a , 12 b  and 12 c    an alternative implementation of a floating body  102  of a floating carrier device  100  and/or of a floating unit  118  is illustrated. As the floating body  102  shown in  FIGS. 12 a , 12 b  and 12 c    has an at least substantially analogous implementation to the floating bodies  12  described in the description of  FIGS. 1 to 10 , the description of  FIGS. 1 to 10  may at least substantially be referred to regarding an implementation of the floating body  102  shown in  FIGS. 12 a , 12 b  and 12 c   . Differently than the floating bodies  12  described in the description of  FIGS. 1 to 10 , the floating body  102  shown in  FIGS. 12 a , 12 b  and 12 c    preferably has a maximum longitudinal extension  144  of more than 180 cm, preferentially more than 200 cm, preferably more than 220 cm and particularly preferably at least substantially 224 cm. In particular, the maximum longitudinal extension  144  of the floating body  102  extends at least substantially parallel to a main extension axis  146  of the floating body  102 , said main extension axis  146  being oriented, in particular in a state when arranged on the water body, at least substantially parallel to the ideal water surface  82 . A maximum transverse extension  148  of the floating body  102  is preferentially implemented identically to a maximum transverse extension of the floating body  12  described in  FIGS. 1 to 10 . The maximum transverse extension  148  of the floating body  102  preferably is at least 50 cm, preferentially at least 55 cm, preferably at least 60 cm and very particularly preferably at least substantially 60 cm. In particular, the maximum transverse extension  148  of the floating body  102  is oriented at least substantially perpendicularly to the maximum longitudinal extension  144  of the floating body  102  and is, in particular in a state when arranged on the water body, oriented at least substantially parallel to the ideal water surface  82 . The floating body  102  delimits a hollow space  150 , in particular precisely one hollow space  150 , which has a maximum volume of more than 400 liters, preferably more than 500 liters, preferentially more than 700 liters, particularly preferably more than 720 liters and very preferentially at least substantially 730 liters. Preferably the maximum volume of the hollow space  150  of the floating body  102  is realized by precisely one recess that is delimited by the floating body  102 .

     The floating body  102  comprises on an upper side of the floating body  102  three receiving regions  22 ,  158  for the carrier structure  104 , in particular for the purpose of receiving the carrier structure  104  at least partly. The three receiving regions  22 ,  158  extend at least substantially completely over the maximum transverse extension  148  of the floating body  102 . Viewed along the maximum longitudinal extension  144  and/or the main extension axis  146  of the floating body  102 , one receiving region  22  of the three receiving regions  22 ,  158  is arranged centrally on the floating body  102 . The receiving region  22  of the three receiving regions  22 ,  158  is shown in particular in  FIG. 12 c    in a cross section. In particular, the receiving region  22  is configured to receive at least one carrier element  36  and/or a bracing element  108  of the carrier structure  104  at least in a form-fit manner, wherein in particular the carrier element  36  and/or the bracing element  108  of the carrier structure  104  adjoins the floating body  102 , in particular in an assembled state. The floating body  102  preferentially forms a projection  156  within the receiving region  22  of the three receiving regions  22 ,  158 , wherein in particular the carrier element  36  and/or the bracing element  108  of the carrier structure  104  are/is configured, when the carrier structure  104  is supported on the floating body  102 , to receive the projection  156  at least partly, in particular at least to a large extent.

Viewed along the maximum longitudinal extension  144  and/or the main extension axis  146  of the floating body  102 , two receiving regions  158  of the three receiving regions  22 ,  158  are arranged each on one end of the floating body  102  respectively. In particular, the two receiving regions  158  of the three receiving regions  22 ,  158  are arranged on two ends of the floating body  102  that face away from each other. The two receiving regions  158  of the three receiving regions  22 ,  158  are in particular configured to receive two carrier elements  36  and/or two bracing elements  108  of the carrier structure  104 . The two receiving regions  108  of the three receiving regions  22 ,  158  and/or the two carrier elements  36  and/or the two bracing elements  108  of the carrier structure  104  are preferably configured for tensioning the floating body  102  on the carrier structure  104  in a direction that is oriented at least substantially parallel to the maximum longitudinal extension  144  and/or to the main extension axis  146  of the floating body  102 , and/or for securing and/or holding the floating body  102  against a movement relative to the carrier structure  104  in the direction that is oriented at least substantially parallel to the maximum longitudinal extension  144  and/or to the main extension axis  146  of the floating body  102 . The floating body  102  comprises two further receiving regions  20 , which are respectively arranged on a side wall  16 ,  18  of the floating body  102 . The two further receiving regions  20  extend at least substantially parallel to the maximum longitudinal extension  144  and/or the main extension axis  146  of the floating body  102 . The two further receiving regions  20  are configured to at least partly receive the carrier structure  104 , in particular a carrier element  36  and/or a bracing element  108  of the carrier structure  104 . Preferentially a minimum distance  160  of the two further receiving regions  20  from an underside  32  of the floating body  102  extends by at least 30 cm, preferably at least 35 cm and particularly preferably at least 40 cm. The two further receiving regions  20  are preferably configured, by way of a cooperation with the carrier structure  104 , for a holding and/or securing of the floating body  102  against a movement relative to the carrier structure  104  in a direction that is oriented at least substantially perpendicularly to the maximum longitudinal extension  144  and/or to the main extension axis  146  of the floating body  102 .

     However, implementations of the floating body  102 , having on the upper side  24  a number of receiving regions  22 ,  158  that differs from three, are also conceivable, for example only having a receiving region  22  that is arranged centrally on the upper side  24  of the floating body  24 . 
       FIG. 13  shows an alternative implementation of a solar device  98 , comprising a floating carrier device  100  and a plurality of, in particular eighteen, solar elements  10 . The floating carrier device  100  comprises four floating bodies  102 , which in particular respectively correspond to the floating body  102  described regarding  FIGS. 12 a , 12 b  and 12 c   . The floating carrier device  100  comprises a carrier structure  104 , which is coupled with the floating bodies  102  and which is in particular configured for a support of the solar elements  10  on the floating bodies  102 . Alternatively it is conceivable that the floating carrier device  100  comprises a number of floating bodies  102  that differs from four, preferably at least three. Alternatively or additionally it is conceivable that the floating carrier device  100  is configured to receive a number of solar elements  10  differing from eighteen. The floating carrier device  100  depicted in  FIG. 13  has an implementation that is at least substantially analogous to the floating carrier device  8  described in the description of  FIGS. 1 to 10 , and therefore the description of  FIGS. 1 to 10  may at least substantially be referred to in regard to an implementation of the floating carrier device  100  shown in  FIG. 13 . Differently than the floating carrier device  8  described in the description of  FIGS. 1 to 10 , the floating carrier device  100 , in particular the carrier structure  104 , shown in  FIG. 13  preferably has a greater maximum longitudinal extension  162 . In particular, the maximum longitudinal extension  162  of the floating carrier device  100 , in particular of the carrier structure  104 , is oriented at least substantially parallel to a main extension axis  164  of the floating carrier device  100 , in particular the carrier structure  104 , which is in particular oriented at least substantially parallel to an ideal water surface  82 .

Preferably, in an assembled state of the solar device  98  and/or in a state of the solar elements  10  being arranged on the carrier structure  104 , the maximum longitudinal extension  166  of the solar elements  10  is oriented at least substantially parallel to the maximum longitudinal extension  170  of the carrier structure  104 , in particular of a bracing element  136  of the carrier structure  104 , and/or oriented parallel to the floating carrier device  100 , in particular to the main extension axis  164  of the floating carrier device  100 . In a state when arranged on the carrier structure  104 , the solar elements  10  are preferably arranged along the maximum longitudinal extension  166  of the solar elements  10  in two rows  168 , which are in particular arranged at least substantially parallel to one another. Especially preferentially the maximum longitudinal extension  166  of the solar elements  10  is to be understood as a maximum longitudinal extension  166  of all solar elements  10  of the solar device  98  in a state when arranged on the carrier structure  104 , and is in particular realized differently from a maximum longitudinal extension of the individual solar elements  10 . Preferably, in the assembled state of the solar device  98  and/or in the state when the solar elements  10  are arranged on the carrier structure  104 , the carrier structure  104 , in particular the at least one bracing element  136 , extends over the maximum longitudinal extension  166  of the solar elements  10  at least to a large extent, in particular at least substantially completely, wherein in particular the solar elements  10 , in particular a row  168  of the solar elements  10 , are/is arranged, in particular fixated, on the bracing element  136 . 
     The carrier structure  104  has a maximum longitudinal extension  170  of at least 4 m, preferentially at least 6 m, preferably at least 8 m and particularly preferably at least 9 m. 
     Preferably the maximum longitudinal extension  170  of the carrier structure  104  is at least substantially parallel to the main extension axis  164  of the floating carrier device  100 , in particular of the carrier structure  104 , and/or the maximum longitudinal extension  170  of the carrier structure  104  is oriented at least substantially parallel to the ideal water surface  82 , in particular in a floating state of the floating carrier device  100 . Preferably, viewed in at least one plane, in particular a plane that is oriented at least substantially parallel to a main extension plane of the floating carrier device  100 , in particular of the carrier structure  104 , and/or oriented, in particular in a floating state of the floating carrier device  100 , at least substantially parallel to the ideal water surface  82 , the floating carrier device  100 , in particular the carrier structure  104 , has an at least substantially rectangular basic shape, wherein in particular the maximum longitudinal extension  170  of the carrier structure  104  extends along a longest side of the basic shape. In particular, the maximum longitudinal extension  170  of the carrier structure  104  is maximally 20 m, preferentially maximally 15 m and preferably no more than 10 m. The maximum longitudinal extension  170  of the carrier structure  104  preferentially extends at least to a large extent, in particular at least substantially completely, over a maximum longitudinal extension  162  of the floating carrier device  100 . The carrier structure  104  has a maximum transverse extension  172  of at least 3 m, preferably at least 4 m and preferentially at least 4.5 m. The maximum transverse extension  172  of the carrier structure  104  is preferably oriented at least substantially parallel to the main extension plane of the floating carrier device  100 , in particular of the carrier structure  104 , and/or is oriented at least substantially parallel to the ideal water surface  82 , in particular in a floating state of the floating carrier device  100 . In particular, the maximum transverse extension  172  of the carrier structure  104  is oriented at least substantially perpendicularly to the maximum longitudinal extension  170  of the carrier structure  104 . Preferentially, viewed in at least one plane, in particular in a plane that is oriented at least substantially parallel to the main extension plane of the floating carrier device  100 , in particular of the carrier structure  104 , and/or is oriented, in particular in a floating state of the floating carrier device  100 , at least substantially parallel to the ideal water surface  82 , the floating carrier device  100 , in particular the carrier structure  104 , has an at least substantially rectangular basic shape, wherein in particular the maximum transverse extension  172  of the carrier structure  104  extends along a side of the basis shape that is in particular implemented differently from the longest side of the basic shape. In particular, the maximum transverse extension  172  of the carrier structure  104  is maximally 20 m, preferably maximally 15 m and preferentially maximally 10 m. Preferably the maximum transverse extension  172  of the carrier structure  104  extends at least to a large extent, in particular at least substantially completely, over a maximum transverse extension of the floating carrier device  100 . 
     The carrier structure  104  comprises four bracing elements  136 , which are configured for a support of the plurality of solar elements  10  along the maximum longitudinal extension  170  of the carrier structure  104 , wherein the bracing elements  136  each have a maximum longitudinal extension  174  of at least 4 m, preferably at least 6 m, preferentially at least 8 m and particularly preferably at least 9 m. Preferably the bracing elements  136 , in particular the maximum longitudinal extension  174  of the bracing elements  136 , extend at least substantially parallel to the maximum longitudinal extension  170  of the carrier structure  104 . In particular, the bracing elements  136  are respectively embodied as a strut with a hollow profile and with an opening that extends along the maximum longitudinal extension  174  of the bracing elements  136  and is in particular located on an underside of the respective bracing element  136 . However, other implementations of the bracing elements  136  are also conceivable, for example as rails, as beams, as bars, or the like. It is conceivable that, in particular viewed in a section plane that is oriented at least substantially perpendicularly to the maximum longitudinal extension  174  of the bracing elements  136 , the bracing elements  136  are embodied structurally identical and/or identical to a carrier element  36 , in particular to the carrier elements  36  of the carrier structure  14  shown in  FIGS. 1 to 10 . It is in particular conceivable that the bracing elements  136  are respectively embodied as a C profile, that they are embodied at least partially open when viewed along the maximum longitudinal extension  174  of the bracing elements  136 , and/or that in an assembled operation state, when viewed in a direction from an upper side of the bracing elements  136  towards the water surface  82 , they have at least one downwards-extending slant surface. In particular, the bracing elements  136 , in particular the maximum longitudinal extension  174  of the bracing elements  136 , extend/extends at least largely, in particular at least substantially completely, over the maximum longitudinal extension(s)  170 ,  162  of the carrier structure  104  and/or of the floating carrier device  100 . In particular, for the purpose of supporting the solar elements  10  over a large portion of the maximum longitudinal extension  170 ,  174  of the carrier structure  104  and/or of the bracing elements  136 , in particular over the at least substantially complete maximum longitudinal extension  170 ,  174  of the carrier structure  104  and/or of the bracing elements  136 , the carrier structure  104 , in particular the bracing elements  136 , is/are configured to receive solar elements  10 . Other implementations of the carrier structure  104  are also conceivable, for example with a number of bracing elements  136  differing from four. The bracing elements  136  are preferably each embodied to be hollow and/or they delimit at least one recess, preferentially along their maximum longitudinal extension  174 . In particular, the bracing elements  136  are configured for guiding cables to the solar elements  10  and/or away from the solar elements  10 , in particular within or in the recess. Preferentially cables of the solar elements  10 , of a power converter device  50  and/or of an external unit are arranged at least partially along the maximum longitudinal extension  174  of the bracing elements  136  on and/or within at least one of the bracing elements  136 . It is conceivable that the cables are fixated on the bracing element(s)  136  via at least one fixation means, e.g. a clamp, a loop, a screw connection or the like. 
       FIG. 14  shows a further alternative implementation of a floating carrier device  106 . A carrier structure  176  of the floating carrier device  106  is configured to transfer a support force of a power converter device  50  to two floating bodies  102  of the floating carrier device  106 . It is also conceivable that the carrier structure  176  is configured to transfer a support force of a functional device that is implemented differently than the power converter device  50  to the floating bodies  102 , the functional device being embodied, for example, as a connection hub for a bundling of a plurality of solar devices and/or solar boats, in particular of supply and/or transmission cables of a plurality of solar devices and/or solar boats, and/or being embodied as a monitoring device for a monitoring of solar boats and/or solar devices which are connected with the functional device and/or surround the functional device (see  FIG. 1 ). The floating carrier device  106  illustrated in  FIG. 14  has an implementation at least substantially analogous to the floating carrier device  9  described in the description of  FIG. 3 , and therefore the description of  FIG. 3  may be at least substantially referred to as regards an implementation of the floating carrier device  106  shown in  FIG. 14 . Differently than the floating carrier device  9  described in the description of  FIG. 3 , the floating carrier device  106  illustrated in  FIG. 14  is preferably configured to realize the power converter device  50  in such a way that it is at least substantially completely walkable in a circulating fashion. The floating carrier device  106  comprises six bottom elements  178 , which are arranged at least substantially parallel to a maximum longitudinal extension  180  of the floating carrier device  106  and which lie upon the carrier structure  176 . In particular, a respective longitudinal axis of the bottom elements  178  is arranged at least substantially parallel to the maximum longitudinal extension  180  of the floating carrier device  106 . Respectively three bottom elements  178  of the six bottom elements  178  form a further alleyway  92 , which extends at least substantially parallel to a maximum longitudinal extension  180  of the floating carrier device  106 . The two further alleyways  92  are respectively arranged on the carrier structure  176  on sides of the power converter device  50  that face away from each other. It is however also conceivable that the floating carrier device  106  comprises a number of bottom elements  178  that differs from six, the bottom elements  178  being in particular arranged at least substantially perpendicularly to the maximum longitudinal extension  180  of the floating carrier device  106 . The floating carrier device  106  comprises two cable channel elements  182 , which are arranged at least substantially parallel to the bottom elements  178  and/or to the maximum longitudinal extension  180  of the floating carrier device  106 . In particular, a respective longitudinal axis of the cable channel elements  182  is arranged at least substantially parallel to the maximum longitudinal extension  180  of the floating carrier device  106  and/or to the bottom elements  178 . In particular, the cable channel elements  182  are respectively embodied as an at least substantially panel-shaped bottom element delimiting at least one recess (not shown in the figures) for a guiding of cables. Other implementations of the cable channel elements  182  are also conceivable. In particular, the cable channel elements  182  are embodied, on a respective upper side  184  of the cable channel elements  182 , in an anti-skid fashion. Preferentially the cable channel elements  182  are configured for guiding cables of a solar device from at least one solar element  10  to the power converter device  50  and/or from the power converter device  50  to an external unit (not shown in the figures), for example a transformer. The bottom elements  178  and the cable channel elements  182  together form a walkable surface, which is in particular realized at least substantially completely around the power converter device  50 . In particular, the power converter device  50  is implemented in such a way that it is completely walkable in a circulating fashion via the bottom elements  178  and the cable channel elements  182 . However, other implementations of the floating carrier device  106  are conceivable, for example with a number of cable channel elements  182  that differs from two. The bottom elements  178  and/or the cable channel elements  182  cover the floating bodies  102  of the floating carrier device  106 , in particular upper sides of the floating bodies  102  of the floating carrier device  106 , at least to a large extent, in particular at least substantially completely. The power converter device  50  is preferentially arranged between the two cable channel elements  182  and/or between the two further alleyways  92 . In particular, the two further alleyways  92  have a maximum transverse extension  94  of at least 80 cm, preferably at least 90 cm and preferentially at least 100 cm. Preferably the two further alleyways  92 , in particular a maximum longitudinal extension of the two further alleyways  92  on the floating carrier device  106 , respectively extend at least substantially completely over a maximum longitudinal extension  180  of the floating carrier device  106 . The bottom elements  178  and/or the cable channel elements  182  preferentially lie upon the carrier structure  176 , in particular upon carrier elements  186  of the carrier structure  176 . Preferably the bottom elements  178  and/or the cable channel elements  182  are fixated on the carrier structure  176 , in particular on the carrier elements  186 . 
     Preferentially the bottom elements  178  delimit a plurality of pass-throughs, in particular in a manner distributed over a main extension plane of the bottom elements  178 . In a state when the bottom elements  178  are fixated, in particular mounted, on the carrier structure  176 , the pass-throughs extend from an upper side of the bottom elements  178  over an entire height of the bottom elements  178  to an underside of the bottom elements  178 . The pass-throughs are preferably configured for conveying water from the upper side of the bottom elements  178  through the bottom elements  178  in a perpendicular direction. Preferentially the pass-throughs are configured to at least substantially prevent a retention of water on the bottom elements  178 . Preferably the bottom elements  178  are embodied, in particular on an upper side of the bottom elements  178 , at least partly in an anti-skid fashion. In a preferred implementation the bottom elements  178  form edgings delimiting the pass-throughs (not shown in the figures), which have an anti-skid effect. For example, the pass-throughs are embodied to be round or angular. Preferentially the pass-throughs and/or the edgings of one bottom element  178  feature several different implementations. The bottom elements  178  are preferably embodied of aluminum or of, in particular furrowed or perforated, sheet metal. However, other implementations of the bottom elements  178  are also conceivable. 
     The carrier structure  176  comprises two fixation elements  190  for a support of the power converter device  50  and/or of a functional device. The two fixation elements  190  are respectively arranged between the two further alleyways  92  and/or between the two cable channel elements  182 , and extend, in particular at least substantially perpendicularly to the ideal water surface  82  and/or to the main extension plane of the floating carrier device  106 , from the carrier elements  186  of the carrier structure  176  which support the bottom elements  178  and/or the cable channel elements  182 , from below the further alleyways  92  and/or the cable channel elements  182 , up to above the further alleyways  92  and/or the cable channel elements  182 . In particular, the fixation elements  190  are embodied as hollow profiles. The fixation elements  190  delimit a plurality of openings for a modular fixation of the power converter device  50  and/or of the functional device. However, other implementations of the carrier structure  176 , in particular of the fixation elements  190 , are also conceivable.
