Description

Assembly, Substructure and Photovoltaic System {ASSEMBLY, SUB-STRUCTURE AND PHOTOVOLTAIC SYSTEM}

The present invention relates to an assembly for receiving a photovoltaic module, a substructure having at least two such assemblies and a photovoltaic system.

Solar radiation can be converted into electrical energy by a photovoltaic module. Photovoltaic modules are generally mounted on an undercarriage, which is attached to a substrate, such as a roof. Conventionally, photovoltaic modules have been mounted on a mounting tripod on a facility known as a flat roof or outdoor array. In this case, one single photovoltaic module is mounted on each mounting tripod. These mounting tripods must additionally have weight or be screwed to the substrate to ensure the required stability, for example, against buoyancy when the wind blows into the installation. Thus, the flat roof must be sufficiently stable to withstand a considerable amount of additional weight and / or lead holes must be formed through the roof surface and reliably waterproof.

It is required to specify an assembly containing the photovoltaic module, a substructure having at least two such assemblies, and a photovoltaic system for mounting the photovoltaic module in various ways.

In one embodiment of the invention, the assembly comprises first and second devices, each receiving at least one photovoltaic module. The first device has one second end coupled to the first end of the second device, such that the second end of the first device located opposite the first end and the second end of the second device located opposite the first end The ends are arranged spaced apart from each other on the surface. The surface is located spaced from the joined first ends.

In one exemplary embodiment, one receiving area of the first and second devices for the at least one photovoltaic module each extends from the first end to the second end of the first non-second device.

Is arranged between the second end of the second end and the second end of the second device.

The first end arranged between the second ends has the advantage that when the photovoltaic module is coupled to the assembly, the main surfaces of the photovoltaic module with respect to the incident light beams face in opposite directions to each other. Additionally, the first and second devices can each form an angle of less than 90 °, in particular an angle of less than 20 °, between the second side and the at least one base member. In particular, the device may form an angle of about 18 ° with the base member, which corresponds to the minimum sun angle in winter in Germany. Different angles may be formed at different locations, which may be determined as a function of the minimum sun position. The angle of the first device and the angle of the second device may be of the same size; They may be formed at different angles.

In one exemplary embodiment, the assembly includes a coupling device coupling the first end of the first device to the first end of the second device, the coupling device having a first element and a second element. The long rods of the first device and the long rods of the second device are respectively coupled at opposite sides of the first element to couple the first device to the second device. The second element is designed to be coupled to the first element such that at least one particular photovoltaic module is fixed in the correct position at the particular first end by the coupling device.

Due to this coupling device, the assembly is stabilized such that the long rods of the first and second devices are held against each other, forming an essentially arch-like self-support. In addition, two photovoltaic modules can be easily coupled to the device using the same coupling device. In addition, fewer assembly steps are required in this way.

In one embodiment, the assembly comprises first and second base members, each of which is arranged to traverse in the longitudinal direction of the long rod apart from one another on the surface, wherein the two long rods of the first device are It is coupled to the first base member at the second end, and the two elongate rods of the second device are coupled to the second base member at the second end of the second device. Using such base members, the assembly can be mounted on a surface, such as a flat roof, an inclined roof or an outdoor area.

The elongate rods can each be insertably connected to the base member. The base members may each be designed to receive one attachment member for mounting at least one particular photovoltaic module. For example, a second end of the photovoltaic module can be coupled to the device.

At least one elongate rod of the base member may be coupled to the first base member and the second base member to couple the first base member to the second base member. This will essentially prevent the base members from moving relative to each other.

In another exemplary embodiment, the assembly includes at least two triangularly shaped side members, each side member being joined to another triangular member at the edge of the triangle so that three sides are surrounded. Both sides are designed to be coupled to at least one photovoltaic module. The third side is designed to be arranged on the surface.

However, the present invention provides many applicable novel concepts that can be implemented with a wide variety of specific details. The specific embodiments discussed are merely illustrative of specific methods for the manufacture and use of the invention, which do not limit the scope of the invention.

1 shows an assembly 100 containing two photovoltaic modules 148, 149 (FIG. 3). Assembly 100 is arranged on surface 101. The assembly 100 includes two triangularly shaped side members 140 and 141. The triangular shaped side members 140 and 141 are arranged on the surface spaced apart from one another, essentially one side arranged along the surface 101, in particular parallel to the surface 101. The two side members 140 and 141 are joined together. The first side member 140 has three edges 142, 144 and 146. The second side member 141 has three edges 143, 145 and 147. The two side members 140 and 141 are joined together at corresponding corners 142 and 143, 144 and 145, 146 and 147 to accommodate any of the photovoltaic modules 148 and / or 149. Two receiving regions 113 and 123 are formed, respectively.

Receiving regions 113 and 123 are arranged obliquely to surface 101, respectively. When photovoltaic modules 148, 149 are mounted to assembly 100 (FIG. 3), photovoltaic modules 148, 149 are inclined relative to surface 101. The receiving area 113 forms an angle 103 with the surface. Receiving region 123 forms an angle 104 with the surface. The angles 103 and 104, in particular the magnitude of the angles, are essentially the same. In another exemplary embodiment, the angles 103 and 104 may be different from one another, for example, the angles 103 and 104 may be different from one another by 33% or less, in particular 20% or less. The angles 103 and 104 may differ from each other by greater than 33%, for example by 40% or more. In particular, angles 103 and 104 are each acute, that is to say less than 90 °. In the exemplary embodiment shown, the angle 103 is embossed and the angle 104 is engraved (with respect to the X axis), so that the receiving regions 113 and 123 are inclined to face each other with respect to the surface 101. Are arranged. The vertices of angle 103 are located at edges 142 and 143. The vertices of angle 104 are located at edges 146 and 147.

The assembly 100 includes a first device 110 having a receiving area 113. The assembly includes a second device 120 that includes a receiving area 123. The devices 110 and 120 are arranged inclined relative to the surface 101. Device 110 has a first end 121 arranged at edges 144 and 145. The device 110 has a second end 112 arranged opposite the first end 111 at the corners 142 and 143. The second device 120 has a second end 122 arranged at the edges 146 and 147 opposite the first end 121. The device 110 extends between the first and second ends 111 and 112 to form a receiving area 113. The second device 120 extends between the first and second ends 121 and 122 to form a receiving area 123.

The first and second devices 110 and 120 are joined together at the first ends 111 and 112 by the coupling device 130. The device 110 is coupled to the base member 107 at the second end 112. The second device is coupled to the base member 108 at the second end 122. The device 110 is additionally coupled to the base member 102 at the second end 112. The second device 120 is coupled to the base member 102 at the second end 122. Base member 107 and base member 108 are each coupled to base member 102.

The device 110 includes two elongated rods 114 and 115 in the longitudinal direction formed between the first end 111 and the second end 112. The elongated rods 114 and 115 are arranged transversely in the longitudinal direction and spaced apart by a separation distance 106. The separation distance 106 approximately corresponds to the width of the photovoltaic module 149 to be coupled to the device 110. Devices 110 and 120 are designed to receive photovoltaic modules 148 and 149 vertically or across. Thus, longer sides of the photovoltaic module may be arranged along the long rods 114 and 115, or shorter sides of the photovoltaic module may be arranged along the long rods 114 and 115.

The second device 120, whose structural design is essentially the same as the first device 110, has two long elongated rods 124 and 125 formed longitudinally between the first end 121 and the second end 122. ).

For example, for a vertical assembly of a photovoltaic module, if the photovoltaic module has a width of about 110 cm, the separation distance 106 to a particular point of the long rods 114 and 115 and / or 124 and 125. Has an error of ± 2% at about 110 cm. For smaller modules, the separation distance may be less than 110 cm, for example with an error of ± 2% at 80 cm. For larger modules, the separation distance may be greater than 110 cm, for example with an error of ± 2% at 150 cm. The separation distance 106 for a particular portion of the elongated rod 114 corresponds approximately to the width of the photovoltaic module used.

For example, for the transverse assembly of a photovoltaic module, if the photovoltaic module has a width of about 160 cm, the separation distance 106 for a particular point of the long rods 114 and 115 is ± ± 160 cm. Error of 2%. For smaller modules, the separation distance may be less than 160 cm, for example with an error of ± 2% at 130 cm. For larger modules, the separation distance may be greater than 160 cm, for example with an error of ± 2% at 200 cm. The separation distance 106 for a particular point of the elongated rod 114 corresponds roughly to the width of the photovoltaic module used.

Each of the elongated rods 114, 115, 124 and 125 has a T-shaped cross section, for example, which will be described in more detail with reference to FIG. 7. The elongated rods 114, 115, 124, and 125 may have different shapes designed to support at least one photovoltaic module. The long rods 114, 115, 124 and 125 may be aluminum, galvanized steel or other materials, such as plastic or synthetic, that are stable enough to reliably support the photovoltaic module over a long period of time, for example 20 years. have.

Base member 102 includes two elongated rods 105. Each of the long rods 105 has a T-shaped cross section, for example. The elongated rod 105 may have different shapes designed to prevent the base members 107 and 108 from being moved relative to each other when coupled to the base members 107 and 108, respectively. The elongated rod 105 may be aluminum, galvanized steel or other material, such as plastic or synthetic material, which is sufficiently stable to support the base members 107 and 108 reliably over a long period of time, for example 20 years.

Base members 107 and 108 are designed to be coupled to opposite ends of elongate rod 105, respectively. Base member 107 is designed to be coupled to elongated rods 114 and 115. Base member 108 is designed to couple to elongated rods 124 and 125. Base members 107 and 108 are each designed to be coupled to an elongated rod (not shown), which will be described in more detail in conjunction with FIG. In addition, base members 107 and 108 are designed to receive one or a plurality of weight members 150, respectively. By the weighting member 150, the mounting of the assembly 100 to the surface 101 can be improved.

Surface 101 includes a flat roof, a flat sloped roof, or an outdoor area independent of any structure. The sloped roof is inclined, for example by about 10 degrees or even about 5 degrees. In particular, flat roofs include roofs sealed with thin films, for example roofs sealed with ethylene-propylene-diene-rubber thin films. The thin film may comprise other materials, for example different rubbers or bitumen.

Coupling of the long rods 114 and 124 and 115 and 125 at the first ends 111 and 121 and the engagement member 130 and the long rods 114 and 124 and 115 and 125 at the second ends 112 and 122. ) And the combination of the base members 107 and 108 and the base member 102 form structural support for the two photovoltaic modules. Since the long rods of the first device form an angle 103 with the base member, and the long rods of the second device form an angle 104 with the base member, the receiving regions for the photovoltaic module are each relative to the substrate. Are arranged obliquely. Thus, the receiving regions are arranged in different directions from each other. Thus, the long rods 114 and 124 and 115 and 125 are coupled in a self-supporting manner, so that additional reinforcement in the direction of the surface 101 can be omitted.

2 shows an undercarriage comprising a plurality of assemblies 100 designed to receive 6x8 photovoltaic modules. The undercarriage includes devices 110 and 120 and additional devices 170, 180 and 190. The device is designed as described for devices 110 and 120, respectively.

The device 190 is arranged next to the device 120 in the X-axis direction. The device 190 and / or the elongated rod of the device are coupled to the base member 108 at the second end of the device 190 to which the device 120 is coupled. Device 120 and devices arranged next to device 120 in the X-axis direction, such as device 190, have a common base member 108. The base member 108 extends in the X-axis direction across a number of devices, for example four devices. The base member may extend across more devices, such as six or more devices, or may extend across fewer devices, such as three or fewer devices.

Devices 120 and 190, which are directly attached to each other, have a common elongated rod 125. The two devices, each arranged side by side, have a common elongated rod through the portion where the receiving area is formed for the two photovoltaic modules. The receiving region for the photovoltaic module is formed by the elongated rod 125; This area is provided on the device 120, and the receiving area for the photovoltaic module is formed by the elongated rod 125; This area is provided on the device 190. Thus, in the X-axis direction, with three long rods, two devices 120 and 190 are formed to accommodate two photovoltaic modules.

Devices 180 and 170 are arranged next to the device 110 in the Y-axis direction. Device 110 and device 180 are coupled to a common base member 107. Opposite the base member 107, the device 170 is coupled to an additional base member 160. Structurally equivalent base members 107, 108 and 160 are designed to be coupled to one or more devices on two opposing sides of the base member, respectively. Due to this modular substructure, a large number of different substructures can be formed using a limited number of different structural members.

FIG. 3 shows a photovoltaic system having a portion of the substructure described with reference to FIG. 2 and three rows of 3 × 8 photovoltaic modules coupled to the substructure. Photovoltaic module 148 is coupled to device 120. Photovoltaic module 149 is coupled to device 120. Photovoltaic module 156 is coupled to device 180. Photovoltaic module 157 is coupled to device 170. Photovoltaic module 158 is coupled to device 120. The photovoltaic modules are each coupled to a particular device at a first end by a coupling device 130. One, two or more photovoltaic modules may be coupled to one, two or more devices by a single common coupling device 130. The coupling device extends across the corresponding number of photovoltaic modules. Each photovoltaic module is seated on an elongated rod of the corresponding device.

The module is supported by a long rod and mechanically stable. Two photovoltaic modules that are directly attached to each other in the X-axis direction are seated on a common long rod. Only one photovoltaic module is seated on the elongated rod at the outer edge of the string in the X and / or X axis direction. For example, photovoltaic module 158 and photovoltaic module 148 are seated together on elongated rod 124 at the center between two photovoltaic modules. The elongated rod 114 supports the photovoltaic module 149 and the directly adjacent photovoltaic module 159.

Photovoltaic modules are each arranged on the major face of incident solar light, for example, to convert sunlight into electrical energy. The main plane of incident light is the plane where most of the sunlight arrives during operation. The major surface of the incident light beam faces away from the surface 101. For this conversion, the photovoltaic module comprises a semiconductor stack composed of, for example, silicon or gallium arsenide. Other materials, for example organic solar cells, are also suitable for the corresponding conversion of energy. In particular, the thin film photovoltaic module is introduced such that the semiconductor stack is disposed on the substrate. Such thin-film photovoltaic modules can be used without frames, that is, without using any additional reinforcement frames. Such photovoltaic modules are also called thin film photovoltaic modules. Thin film type photovoltaic modules have better efficiency of scattered radiation than conventional crystal photovoltaic modules.

In the photovoltaic system according to FIG. 3, a thin film type photovoltaic module is preferably used. For example, the Y-axis direction is approximately south. As a result, the photovoltaic modules 149, 159 and 157 are arranged northward. Nevertheless, photovoltaic modules 149, 159, and 157 still efficiently convert radiant energy to electrical energy, because relatively large amounts of scattered radiation are converted by thin film photovoltaic modules. However, the arrangement of photovoltaic systems different from the north-south direction may also be used efficiently, for example, an east-west arrangement or an intermediate arrangement may be used. Due to the assembly with photovoltaic modules on both sides, the efficiency of the photovoltaic system is increased compared to conventional photovoltaic modules with only one side. This is achieved through the use of thin film photovoltaic modules, which may be advantageously operated even if the main face of the incident light beam is arranged northward. However, the crystal photovoltaic module may also be introduced on one side arranged approximately southward, and the thin film photovoltaic module may be used on the opposite side arranged approximately northward. Inverted arrangements are also available. In a further embodiment, crystalline photovoltaic modules are used on both sides.

Since the two rectangular shaped photovoltaic modules are arranged to face each other in the photovoltaic system, the photovoltaic system should be provided with fewer weighting members 150 as a whole than conventional photovoltaic systems. Conventional photovoltaic systems, in which one single photovoltaic module is mounted on a support triangle, should have a weight below since wind can pass through the photovoltaic module and cause buoyancy in the photovoltaic system. To counteract this force, conventional photovoltaic systems have a weight of about 180 to 200 kilograms per square meter of mounted photovoltaic module surface area. Therefore, the substrate must be designed to support a load of this size. This is not always possible, especially with flat roofs.

In the case of a photovoltaic system, for example a photovoltaic system as described in conjunction with FIG. 3, the surface of the photovoltaic module with about 30 kilograms of weighting members 150 per square meter is mounted to the substrate. It is enough to keep it fixed. Since less wind can pass under the photovoltaic module as compared to conventional photovoltaic systems, the weight can be reduced and preferably any additional weight can be omitted entirely. In addition, for two opposing photovoltaic modules, opposing forces are applied which at least partially cancel each other when the photovoltaic module is exposed to wind. For example, under any one of the photovoltaic modules, a vacuum pressure is created to press the photovoltaic system toward the surface 101. Thus, it may be sufficient to apply a load to the photovoltaic system on the edge, namely the base member 108 and the base member located at the opposite end, while there is little or no load on the base members 107 and 160 arranged between them. It may not be. In addition, it may be unnecessary to secure the photovoltaic system with screws to the substrate and / or the number of screw connections may be reduced. Thus, in the case of a flat roof, the screw holes passing through the roof membrane need not be sealed again.

The angles 103 and 104 are formed large, respectively, by the lowest solar altitude in terms of the photovoltaic system so that shadows are not cast by the photovoltaic module positioned in front of the lower photovoltaic module located in the direction of the sun's rays. For example, when the sun's rays are approximately in the Y-axis direction, the photovoltaic modules 157 and 156 are installed inclined relative to the surface 101 so that the shadows of the photovoltaic modules 157 and 156 are at the lowest solar altitude. Does not even extend into the photovoltaic module 149. If the lowest solar altitude is about 18 °, the photovoltaic module may be installed at an angle of less than 18 °, such as about 15 °, relative to the surface 101. In one exemplary embodiment, the angle is greater by about 6 ° such that the photovoltaic module is self-cleaning, for example in case of rain. Due to the mounting of photovoltaic modules of this kind, photovoltaic systems can be provided with a larger surface area photovoltaic module for a given base surface area as a whole compared to conventional photovoltaic systems.

4 shows a detailed view of a photovoltaic system with coupling of long rods 114 and 124 and coupling of photovoltaic modules 148 and 149. The elongated rod 114 is coupled to the coupling device 130 and / or the first member 131 of the coupling device 130 at the first side 133. The elongate rod 124 is coupled to the coupling device 130 and / or the first member 131 of the coupling device 130 at the second side 134 located opposite the first side 133. In particular, the elongated rods 114 and 124 are inserted into recesses of the first member, respectively. Thus, long rods 114 and 124 are joined together in a self-supporting manner.

When the long rods 114 and 124 are coupled to the first member 131 during assembly of the photovoltaic system, the photovoltaic modules 148 and 149 are disposed on the long rods 114 and / or 124. In order to secure the photovoltaic modules 148 and 149 in the correct position, the second member 132 of the coupling device 130 is coupled to the first member 131. The second member 132 is fixed by, for example, frictionally acting on the first member 131 and / or fixed by applying a force, so that the photovoltaic modules 148 and 149 are connected to the first ends 111 and 121. Can be fixed at The second member 132 may include an elastic member that can be locked by the first member 131, for example. The second member 132 may be differently coupled to the first member 131 by, for example, screw connection.

The elongated rod 124 is coupled to the recess 154 (FIG. 6) of the base member. In particular, the elongated rod 124 is inserted into the recess 154 of the base member 108. The photovoltaic module 148 seated on the elongated rod 124 is fixed to the attachment member 109 by a second end 122. Attachment member 109 is coupled to base member 108 at mount 153 (FIG. 6). The attachment member 109 may be fixed by, for example, frictionally acting on the base member 108 and / or fixed by force acting on the photovoltaic module 148. Attachment member 109 may have an elastic member that may be secured to base member 108, for example. The attachment member 109 may be differently coupled to the base member 108, for example by screw connection.

The elongated rod 105 is coupled to an angled member 151 to connect to the base member 108. The angular member 151 is coupled to the base member 108, for example, the angular member 151 is coupled behind the protruding region 155 of the base member 108 (FIG. 6). In particular, the angular member 151 is inserted into the base member 108. Base member 108 is seated on surface 101.

Base member 108 is placed on surface 101. Base member 108 is in contact with surface 101. The weight member 150 is disposed on the raised portion 152 of the base member 108, such as a concrete plate. Other weighting members, such as gravel, sand and / or other materials suitable for weighting the base member 108, may also be used.

6 shows a cross-sectional view of the base member 108. The base member 108 is symmetrically designed and may be uniformly connected on either side of any of a plurality of elongated rods. The base member 108 has a recess 154 that engages the elongated rod of the device. The recess 154 is configured such that one or multiple elongated rods can be inserted therein.

The base member 102 can be coupled to the protruding region 155 of the base member 108. Additionally, the base member 108 has a mount 153 to which the attachment member for the photovoltaic module can be coupled. The base member 108 is designed to receive electrical wires necessary for operation of, for example, a photovoltaic system. In addition, the base member 108 may be used during assembly or as a passage for maintenance of the photovoltaic system.

7 shows a cross section of the elongated rod 115 on which the photovoltaic module 149 and the photovoltaic module 159 are seated. The long rod 115 having a T-shaped cross section is designed to receive the photovoltaic module 149 and the photovoltaic module 159. The long rod is wide enough so that the two photovoltaic modules 149 and 159 are seated in the area on the long rod 115, mechanically supported and reinforced, such as to prevent bending of the photovoltaic modules 149 and 159.

8 illustrates an assembly 100 according to a further exemplary embodiment. Unlike the exemplary embodiment described in conjunction with FIGS. 1-7, the long rods 105, 114, 115, 124, 125 and the base member 108 of the assembly 100 are of the same type, which is illustrated in FIG. 9. Will be described in detail with reference to FIG.

Base member 102 according to the exemplary embodiment of FIG. 8 extends across one or more assemblies, in particular a plurality of assemblies, along one major direction of the entire substructure, as shown in FIG. 9.

In order to erect the two photovoltaic modules 148 and 149, two base members 102 are preferably arranged in parallel on the surface 101, in particular on a flat roof. The separation distance 106 between the base members 102 essentially corresponds to the width of the photovoltaic modules 148, 149. In an exemplary embodiment, the separation distance 106 is built by the base member 108.
