Description

Title of the invention: System for connecting photovoltaic panels to a structure comprising suspended cables Scope of the invention

[0001] The invention relates to a system of photovoltaic panels fixed above a support, at a determined inclination relative to the support, said system comprising support posts fixed on the support, cables suspended between the support posts and means for fixing photovoltaic panels to the cables.

[0002] More specifically, the photovoltaic panel system according to the invention is adapted to free up the space located below said photovoltaic panels, said space being able to be used, for example, for agricultural activities.

[0003] The panels are orientable in order to optimize energy production but also to provide services to agriculture in particular with regard to shading, temperature reduction and temperature ranges, allowing or not all precipitation to pass through, among other things.

[0004] The photovoltaic panel connection system according to the invention is adapted to facilitate the attachment of photovoltaic panels to suspended cables. Prior art

[0005] The use of systems comprising photovoltaic panels, arranged above a support at a predetermined angle to said support, has already been disclosed in the prior art. Several systems of this type, equipped with photovoltaic panels, are currently used in the construction of photovoltaic power plants suitable for electricity production.

[0006] Generally, to create a photovoltaic power plant, photovoltaic panels are fixed to structures positioned on the ground, with said photovoltaic panels remaining close to the ground. This type of installation allows easy access to the photovoltaic panels for maintenance and possible replacement if necessary.

[0007] In the prior art, systems equipped with photovoltaic panels are known, said photovoltaic panels being fixed to a structure at a relatively significant distance from the ground. These systems have the advantage of freeing up ground space and allowing the surface beneath said photovoltaic panels to be used for a purpose other than the production of electrical energy. For example, the practice of positioning photovoltaic panels above parking lots is already known in the prior art. This This type of installation has the advantage of allowing the space to be used for two distinct purposes: on the one hand, parking vehicles, and on the other hand, producing electrical energy through photovoltaic panels installed above the vehicles.

[0008] However, the systems disclosed in the prior art have drawbacks. Indeed, the structures required to fix the photovoltaic panels at a significant distance from the ground are relatively bulky. These systems use a large number of poles to support the installation of the photovoltaic panels, which limits the possibilities for using the space beneath them. In the case of parking lots, the presence of poles is acceptable because they also delineate individual parking spaces. On the other hand, such a large number of poles is a disadvantage if the user wishes to use the space beneath the photovoltaic panels for agricultural activities.

[0009] Furthermore, systems using photovoltaic panels known in the prior art have another drawback. Indeed, the structures supporting the photovoltaic panels, which are located at a specific distance from the ground, are often relatively expensive to produce.

[0010] Consequently, there is a need to propose new structures that allow for the optimal use of the space beneath photovoltaic panels and reduce the production costs associated with said structures. Summary of the invention

[0027] The purpose, object and features of the invention will become clearer upon reading the following description made with reference to the figures in which:

[0028] [Fig. 1] shows a schematic view of a photovoltaic panel system according to the invention, said system being installed in a field,

[0029] [Fig.2] represents a detailed view of a support post for a photovoltaic panel system according to [Fig.1],

[0030] [Fig.3] shows a part of the system according to the invention to represent the fixing of the fixing elements on carrier cables and auxiliary cables,

[0031] [Fig.4] represents the same part of the system according to the invention, as shown in [Fig.3], the photovoltaic panels being installed in a second orientation relative to the support,

[0032] [Fig.5] shows a first embodiment of a fastening element according to the invention, according to a view illustrating a first side,

[0033] [Fig.6] represents the fastening element according to [Fig.5], according to a view illustrating a side opposite to the first side,

[0034] [Fig.7] shows a second embodiment of a fastening element according to the invention, and

[0035] [Fig.8] represents a detailed view of the attachment of a fastening element on a carrier cable.

[0036] Figure 1 shows a schematic view of a photovoltaic panel system 1 according to the invention. Said photovoltaic panel system 1 is positioned on the ground 2, in a field, said ground 2 forming the support for said system of Photovoltaic panels 1. As illustrated in [Fig.1], the photovoltaic panel system 1 comprises a plurality of photovoltaic panels 3 arranged above the ground 2, at a determined inclination relative to said ground 2. The photovoltaic panels may include, for example, double-sided photovoltaic panels.

[0037] According to the example illustrated in [Fig. 1], the photovoltaic panels 3 are positioned at a specific distance from the ground 2 to allow the ground to be used for agricultural activity. In this example, the ground is used to accommodate herds of livestock 30 (also visible in [Fig. 2]) that can graze freely under said photovoltaic panels 3. According to the same example, the photovoltaic panels 3 allow the use of the ground 2 beneath the photovoltaic panels 3 because they are positioned at a specific distance from the ground 2, said distance being between 2 and 10 meters, preferably between 3 and 8 meters, and more preferably between 5 and 7.5 meters.The positioning of the photovoltaic panels 3 above ground level 2 and at such a distance from the ground allows farmers to move freely below the photovoltaic panels, to use their agricultural machinery below said photovoltaic panels 3 in order, in particular, to carry out activities related to the cultivation of agricultural land.

[0038] It is obviously possible to consider other agricultural uses. Indeed, for example, the space available under the photovoltaic panels 3 can be used for growing any kind of vegetation, for example fruit trees, vegetables or even flowers.

[0039] The presence of the photovoltaic panels 3 allows farmers to consider the use of the land 2 as a primary source of income. The system 1 equipped with photovoltaic panels 3 enables the production of electrical energy generated by said system 1, which represents a second source of income for the farmers. Indeed, for example, farmers can lease one or more plots of land to a photovoltaic shade structure operator, said plots comprising systems 1 equipped with photovoltaic panels 3 according to the invention.

[0040] An important aspect of the invention lies in the presence of the photovoltaic panels 3 located above the ground 2 to offer farmers the possibility of optimizing the use of said ground 2. For example, the presence of the photovoltaic panels 3 makes it possible to create shaded areas on the ground surface located below said photovoltaic panels, in order to protect the vegetation cultivated on this ground surface from direct solar radiation, which can sometimes be harmful to crops when said solar radiation is too strong. The presence of the photovoltaic panels also makes it possible to ensure protection for any plant or animal located below said photovoltaic panels, against heavy precipitation, in the form of hail for example.

[0041] According to the present invention, the photovoltaic panels 3 can be fixed to maintain a stationary position during use. According to the present invention, the photovoltaic panels 3 can also be fixed to allow for rotation during use.

[0042] The tilt of the photovoltaic panels 3 allows the amount of solar radiation on the cultivated vegetation below said photovoltaic panels 3 to be adjusted, which in turn regulates the level of solar protection provided by said photovoltaic panels 3.

[0043] Furthermore, the presence of a system 1 equipped with photovoltaic panels 3 according to the invention allows farmers to ensure optimal conditions for crops below said photovoltaic panels 3. Indeed, for example, an irrigation and / or misting system can be integrated within the system 1 equipped with photovoltaic panels 3, thus allowing vegetation or crops to receive appropriate irrigation and / or misting. The presence of such photovoltaic panels 3 then prevents rapid evaporation of the water supplied by the irrigation and / or misting system towards the ground 2.

[0044] In order to optimize the use of the system 1 equipped with photovoltaic panels 3 according to the invention, and for agricultural purposes, it is possible to integrate, at the ends of said system 1, a screen adapted to cover at least part of the ground surface delimited by all the posts 4 forming the support of the system 1 equipped with photovoltaic panels 3. A screen of this type (not shown in [Fig.1]), can be supplied in the form of nets. The purpose of using such a screen is to enhance the greenhouse effect obtained with system 1. Another alternative screen can be achieved by planting trees at an optimal density on a ground area located below the photovoltaic panels 3, thus closing at least part of the space between the poles 4. The perimeter of system 1 equipped with photovoltaic panels 3 according to [Fig.1] can, for example, be partially closed by means of conifer plantations.

[0045] The system 1 equipped with photovoltaic panels 3 can also be used to collect rainwater by fitting said system 1 with gutters (not shown in [Fig. 1]). These gutters are adapted to collect and convey said rainwater thus collected to collection points, such as a cistern, in order to reuse said rainwater. The rainwater thus collected and stored in said cistern can then supply irrigation systems and thus ensure the watering of vegetation or crops located under the photovoltaic panels. 3. Such a watering system can take the form of a drip irrigation system at the base of said crops.

[0046] Fig. 2 shows a detailed view of the system 1 equipped with photovoltaic panels 3 according to Fig. 1, and in particular the means of fixing said photovoltaic panels 3 at a determined distance from the ground 2.

[0047] The system 1, equipped with photovoltaic panels 3, includes support posts 4 fixed to the ground 2. These support posts 4 may be in the form of tubes, profiles, or any other suitable shape. Figure 2 shows only the portion of the support post 4 located outside the ground 2. The support post 4 is anchored in the ground 2, for example, by a deadweight such as a concrete block. The support post 4 may be made of any suitable material, such as steel, aluminum, or a composite material.

[0048] As shown in Figures 1 and 2, the system 1 also includes carrier cables 5 suspended between two opposing support poles 4. The carrier cables 5 are used to secure photovoltaic panels 3. The system 1, equipped with photovoltaic panels 3, also includes auxiliary cables 6, extending essentially parallel to and at a vertical distance from the carrier cables 5. To stiffen the installation, the system 1 includes anchor cables 15, 16 fixed in line with the carrier cables 5 and the auxiliary cables 6, respectively. The anchor cables 15, 16 are adapted to connect the upper part of the support poles 4 to the ground 2, thus preventing deformation of the support poles 4 that could be caused by the weight of the photovoltaic panels 3 during the use of the system 1. Alternatively, a single anchor cable may be used.The single anchor cable can be fixed to the support posts 4, near the top end of the support posts 4, for example in continuity with the carrier cables 5. Alternatively, the single anchor cable can be fixed to the support posts 4, at a distance from the top end of the support posts 4, in an area between the two ends of the carrier cables 5 and the auxiliary cables 6 fixed to the support posts 4.

[0049] As illustrated in [Fig. 2], the photovoltaic panels 3 are fixed by means of support elements 7, which are themselves fixed to the set of support cables 5 and auxiliary cables 6. Each support element 7 comprises a square cross-section at one end and at the other. Each support element 7 is in the form of beams or tubes. The photovoltaic panels 3 are fixed to the support elements 7 to form rows of photovoltaic panels 3. According to the example illustrated in [Fig. 2], a row of photovoltaic panels 3 comprises 10 photovoltaic panels 3. Generally, the row of photovoltaic panels can comprise any quantity of Photovoltaic panels 3, in order to adapt to all types of needs. The ratio R between the length L of two adjacent rows of photovoltaic panels and the distance E between the two adjacent rows is between 2 and 3, preferably between 2 and 2.5, more preferably between 2.15 and 2.25.

[0050] The support elements 7 are fixed to the carrier cables 5 using fastening elements 8. An embodiment of the fastening elements 8 is shown in more detail in figures 3 to 8.

[0051] As shown in [Fig. 2], the fastening element 8 is essentially H-shaped and comprises a first leg 81, a second leg 82, and a connecting element 83. The legs 81 and 82 extend vertically in their operating position. The legs 81 and 82 are fixed at their upper ends to a support cable 5 and at their lower ends to an auxiliary cable 6. In the operating position shown in [Fig. 2], the connecting element 83 extends essentially horizontally. As explained in detail below, the support elements 7 are fixed to the connecting elements 83 by means of pivoting connections, such as bearings, to allow the support elements 7 to rotate relative to the fastening elements 8.

[0052] Part of system 1 according to the invention is shown in figures 3 and 4, in order to explain in detail the operation of system 1.

[0053] Fig. 3 shows that the distance between the carrier cable 5 and the auxiliary cable 6 is not identical at all points of the carrier cable 5 and the auxiliary cable 6.

[0054] As illustrated in [Fig. 3], the distance between the main cable 5 and the auxiliary cable 6 is minimal when considering a median area located near the midpoint of the respective lengths of the main cable 5 and the auxiliary cable 6. The distance between the main cable 5 and the auxiliary cable 6 is large when considering an end area located near the respective ends of the main cable 5 and the auxiliary cable 6. The existence of this difference in distance between the main cable 5 and the auxiliary cable 6 implies that the fasteners 8, which secure the photovoltaic panels 3, have a different shape depending on where they are fixed, between the main cable 5 and the auxiliary cable 6. Furthermore, [Fig.[3] shows that the fastening elements 8 have minimum dimensions when located in a mid-zone, i.e. near the mid-length of the carrier cable 5 and the auxiliary cable 6. The fastening elements 8 have maximum dimensions when located in an end zone, i.e. near the ends of the carrier cable 5 and the auxiliary cable 6.

[0055] The dimensions of the fastening elements 8, and more particularly the length of the first leg 81 and second leg 82 of said fastening elements 8, are such that the respective connecting elements 83 are essentially parallel to each other. in relation to the others. Details of the fixing elements 8 are shown in figures 5 to 8.

[0056] Figure 3 shows the photovoltaic panels 3 at a first inclination relative to the ground 2. Figure 4 shows the photovoltaic panels 3 at a second inclination relative to the ground 2. Figures 3 and 4 show that the photovoltaic panels are mobile in rotation relative to the support cable 5 and the auxiliary cable 6, thanks to the fixing means comprising the support elements 7 and the fixing elements 8.

[0057] The use of the "H" shaped fixing elements 8 allows the photovoltaic panels to be fixed to the carrier cable 5 and the auxiliary cables 6, which makes it possible to stiffen the structure of the system 1 according to the invention.

[0058] Figure 5 shows a detailed view of a first embodiment of a fastening element 8, along a first side of said fastening element 8. As shown in Figure 5, the fastening element 8 comprises the first leg 81 positioned in a substantially vertical direction between the main cable 5 and the auxiliary cable 6. The details of the fastening to the main cable 5 and the auxiliary cables 6 are shown in more detail in Figure 8. The fastening element 8 also has the second leg 82. The first leg 81 and the second leg 82 are essentially parallel. The connecting element 83 is fixed between the first leg 81 and the second leg 82. The assembly consisting of the first leg 81, the second leg 82, and the connecting element 83 essentially forms an "H".

[0059] Depending on their position of use, the first and second legs 81, 82 are positioned in an essentially vertical direction, the connecting element 83 is positioned in an essentially horizontal direction.

[0060] Figure 5 illustrates the connecting element 83 on which a pivot joint 9 is shown. The pivot joint 9 includes actuating means comprising a first element 91 fixed to the connecting element 83. The actuating means also include a second element 92 located at the center of the first element 91, said second element 92 being rotatable relative to said first element 91. The actuating means also include an actuating element 93 in the form, for example, of an electric motor, for driving the rotation of the second element 92 relative to the first element 91. The actuating means also include a control device for controlling the pivoting of the second element 92 relative to the first element 91 within the pivot joint 9.The control device is connected to the actuation element 93 and includes, for example, a meteorological module comprising at least one sensor for collecting meteorological parameters. In this way, . The position of the support element 7, connected to the second element 92, as well as the tilt of the photovoltaic panels 3 fixed to said support element 7, can be controlled. As illustrated in Figures 5, 6, and 7, the second element 92 is provided with an opening or receiving element having an essentially square shape. This square shape allows one end of a first support element 7, which has a square cross-section, to be received. Thus, when the end of the first support element 7 is positioned in the square opening of the second element 92, the rotation of said second element 92 causes the rotation of the first support element 7, while preventing relative movement between said first support element 7 and said second element 92 of the pivot joint 9.

[0061] Fig. 5 shows a freely rotating element 10 fixed on the connecting element 83, said freely rotating element 10 being shown in more detail in Fig. 6.

[0062] Figure 6 shows a view of the fastening element 8, from a side opposite to that shown in Figure 5. As shown in Figure 6, the freely rotating element 10 comprises a first element 11 fixed to the connecting element 83. The center of the freely rotating element 10 is provided with an element 12 adapted to rotate freely relative to the first element 11. The freely rotating element 10 receives one end of a second support element 7. By referring to Figures 3 and 4, it can be understood that, thanks to the presence of the fastening element 8, the end of the first support element 7 is received inside the pivot joint 9, thus allowing said first support element 7 to be oriented relative to the ground by means of said pivot joint 9.Furthermore, the end of said second support element 7 is received inside the freely rotating element 10, thus allowing the end of the second support element 7 to follow the movement of the first support element 7, the latter being driven in motion by means of the pivot joint 9. As shown in [Fig. 6], the element 12 of the freely rotating element 10 is provided with an essentially square opening or receiving element. This means that an end of a support element 7, having a square cross-section, can be received inside the element 12 of the freely rotating element 10.

[0063] Thus, the fastening element 8, as shown in Figures 5 and 6, can be used in the system 1 according to the invention as an intermediate element for connecting two support elements 7 together. As shown in [Fig. 5], along a first side of the fastening element 8, the second element 92 can receive one end of a first support element 7 in order to actuate said first end of said first support element 7 by means of the actuating element 93. As shown in [Fig. 6], along a side opposite to the first side of the fastening element 8, the freely rotating element 10 can receive one end of a second support element 7.

[0064] Therefore, within the fixing element 8, the swivel joint 9 and the free-rotating element 10 each include an opening adapted to receive one end of a support element 7.

[0065] Figure 7 shows a second embodiment of a fastening element 8, on which only a freely rotating element 10 is fixed, between the first leg 81 and the second leg 82. Such a fastening element 8 can be used at the end of a system 1 according to the invention. According to this embodiment of the fastening element 8, a swivel joint 9 can optionally be fixed instead of said freely rotating element 10 on the connecting element 83.

[0066] Figure 8 shows a detailed view of the attachment of the fastening element 8 to a support cable 5. Figure 8 shows the support cable 5 to which the upper end of a first leg 81 is attached. This upper end of the first leg 81 comprises a first element 181 and a second element 182. A first block 30 is fixed between the two ends of the first element 181 and the second element 182 by means of a fastening assembly 40 consisting, for example, of a screw and a bolt. The blocks 30 and 31 are each provided with a substantially semi-circular recess. The recess in blocks 30 and 31 can receive the section of the carrier cable 5, thus allowing the fixing of said blocks 30 and 31 on the outside of said carrier cable 5. The second block 31 is fixed to the first block 30 with bolts in order to secure the position of the carrier cable 5 between the first and second blocks 30, 31.The lower end of leg 81 can be fixed, in the same way, to an auxiliary cable 6.

[0067] The system 1 according to the invention may also include a coating adapted to cover the support above which the system is fixed, said coating being adapted to increase the reflection of solar radiation on said support.

[0068] The present invention also relates to a photovoltaic shade structure comprising system 1 according to the invention.

[0069] The embodiments described above are given as examples only.
