[0044] By way of alternative, the number of reinforcing bars or beams and the arrangement of the reinforcing bars and beams may differ from that described above. In one example, reinforcing beams 54 and 56 may not be present. In another example, bars 50 and 52 may not be present. In yet another example, bar 36 may not be present.

[0045] As an alternative, the position of the lifting rings 64 may differ from that described above. In one example, the lifting rings 64 are mounted movable relative to the bars 30 and 32. In another example, each lifting ring 64 is mounted movable relative to one of the feet 26.

[0046] According to one embodiment, the support 20 can receive first and second photovoltaic panels 10, the first photovoltaic panel 10 resting on the second frame 42 and the second photovoltaic panel 10 resting on the third frame 48. According to one embodiment, the support 20 includes locking means, not shown, for example clamps, of the first photovoltaic panel 10 on the second frame 42 and of the second photovoltaic panel 10 on the third frame 48. As an alternative, the first photovoltaic panel 10 is mounted tightly in the second frame 42 and the second photovoltaic panel 10 is mounted tightly in the third frame 48.

[0047] The assembly comprising the third bar 30, the fifth bar 38, and the seventh bar 44 forms a triangle, preferably isosceles. Similarly, the assembly comprising the fourth bar 32, the sixth bar 40, and the eighth bar 46 forms a triangle, preferably isosceles. Generally, the angle between the third bar 30 and the fifth bar 38 depends on the intended application. In one embodiment, the angle between the third bar 30 and the fifth bar 38 is between 5° and 10°. However, for certain applications, the angle between the third bar 30 and the fifth bar 38 may be greater than 10°, for example, when it is desired to maximize electricity production in an east-west orientation.

[0048] The photovoltaic structure 5 may further include other electronic devices, for example an inverter and / or a battery of electrical accumulators and / or electrical cables and / or a protective box allowing the photovoltaic panels to be connected to the electrical distribution network.

[0049] According to one embodiment, each bar 22, 24, 30, 32, 36, 38, 40, 44, 46, 50, 52, 54, 56 has a circular, square, or rectangular cross-section. According to one embodiment, each bar 22, 24, 30, 32, 36, 38, 40, 44, 46, 50, 52, 54, 56 corresponds to a hollow or solid tube. According to one embodiment, each bar 22, 24, 30, 32, 36, 38, 40, 44, 46, 50, 52, 54, 56 is made of steel or aluminum.

[0050] According to one embodiment, the height of a photovoltaic structure 10, measured along a direction orthogonal to the plane on which the first frame 42 rests, is between 80 mm and 180 mm, for example less than 150 mm. According to one embodiment, the length of the first and second bars 22, 24 is between 800 mm and 2500 mm, for example approximately 2050 mm. According to one embodiment, the width of the first and second openings 61, 63, measured along the direction of the third bar 30, is between 500 mm and 1000 mm, for example approximately 800 mm.

[0051] According to one embodiment, the weight of the support is between 25 kg and 40 kg.

[0052] According to one embodiment, each bar 22, 24, 30, 32, 36, 38, 40, 44, 46, 50, 52, 54, 56 is fixed to other bars by rigid connections, made for example by welding or riveting. Preferably, the support 20 has a unit structure. According to another embodiment, each of the connections between the fifth bar 38 and the The third bar 30, between the seventh bar 44 and the third bar 30, between the sixth bar 40 and the fourth bar 32, and between the eighth bar 46 and the fourth bar 32 can be a movable link, the fifth bar 38 not being connected to the seventh bar 44 and the sixth bar 40 not being connected to the eighth bar 46. This advantageously allows the tilt of the photovoltaic panels to be modified relative to a horizontal plane.

[0053] The number of mechanical parts composing the support 20 is advantageously reduced to the bare minimum, the vast majority of the parts being welded together. The support 20 thus forms a unit structure, that is to say, not composed of a set of components assembled together by screws, but composed of bars, feet, lifting rings, and transport guides, all assembled by welding at the factory. This advantageously reduces the manufacturing cost and the installation cost of the photovoltaic structures. Furthermore, this advantageously increases the speed of installation and removal of the photovoltaic structures 5.

[0054] As described in more detail below, the photovoltaic structures 5 are stackable. This advantageously allows for a dense and stable stacking of the photovoltaic structures 5, thus enabling safe and inexpensive transport of the photovoltaic structures 5.

[0055] Advantageously, the support 20 exhibits significant rigidity and strength, particularly due to the fact that its components are welded together. Furthermore, the support 20 advantageously provides good electrical continuity, such that there is only one ground point for each support 20. In addition, good electrical contacts can be achieved between the photovoltaic panels 10 and the support 20. Moreover, good electrical contacts can be achieved between interconnected photovoltaic structures 5.

[0056] Figure 3 is an exploded view of an example of a photovoltaic panel 10.

[0057] The photovoltaic panel 10 comprises a stack of a backing sheet 11, for example made of polymer or glass, a backing film 12, a layer of solar cells 13, a fronting film 14, and a glass plate 15. The solar cells 13 are connected to each other, in series or in a series-parallel arrangement, between a positive terminal and a negative terminal. The photovoltaic panel 10 further includes a junction box 16 comprising the positive and negative terminals as well as cables for interconnecting the photovoltaic panels. Such a photovoltaic panel 10, called a frameless photovoltaic panel, has a thickness of between 4 mm and 8 mm or more. The photovoltaic panel 10 may further include a frame 17 holding the stack of the backing sheet 11, the backing film 12, the layer of solar cells 13, the fronting film 14, and the glass plate. 15. This is why such a photovoltaic panel 10 is also called a framed photovoltaic panel. According to one embodiment, the framed photovoltaic panel has a thickness of between 30 mm and 50 mm, a longer side of approximately 2000 mm and a shorter side of 1130 mm.

[0058] According to one embodiment, when used for the support of framed photovoltaic panels 10, the support 20 may not include the tenth and eleventh bars 50 and 52 and the reinforcing beams 54 and 56.

[0059] Each foot 26 of the photovoltaic structure 5 is configured to cooperate with the foot 26 of another photovoltaic structure 5. This advantageously allows the photovoltaic structures 5 to be stacked on top of each other, in particular to transport several photovoltaic structures 5 simultaneously. As an example, a stack can include from two to twenty photovoltaic structures 5 on top of each other.

[0060] Fig. 4 is a partial and schematic perspective view of one embodiment of foot 26.

[0061] The foot 26 comprises an upper portion 65 and a lower portion 66. In the embodiment illustrated in [Fig. 4], the upper portion 65 has a hollow tubular shape with axis D and a circular cross-section, and the lower portion 66 has a tubular shape with axis D and a circular cross-section. The diameter of the lower portion 66 is smaller than the internal diameter of the hollow tubular upper portion 65.

[0062] Fig. 5 is a partial, schematic side view of a stack of two photovoltaic structures 5 as shown in Figures 1 and 2 and for which the feet 26 are as shown in Fig. 4.

[0063] The lower portion 66 of each leg 26 of the photovoltaic structure 5 in the upper position in [Fig. 5] penetrates the upper portion 65 of one of the legs 26 of the photovoltaic structure 5 in the lower position in [Fig. 5]. As a result, the photovoltaic structure 5 in the upper position in [Fig. 5] cannot move in a horizontal direction relative to the photovoltaic structure 5 in the lower position in [Fig. 5].

[0064] Fig. 6 is a partial and schematic perspective view of another embodiment of foot 26.

[0065] As with the foot 26 shown in [Fig. 4], the foot 26 illustrated in [Fig. 6] comprises the upper portion 65 and the lower portion 66. In the embodiment illustrated in [Fig. 6], the upper portion 65 has a tubular shape with axis D and a circular cross-section, and the lower portion 66 has a hollow frustoconical shape with axis D, the apex of which is located on the side of the upper portion 65. The internal diameter of the base of the lower portion 66 is greater than the diameter of the tubular upper portion 65, so that, in a stack of two photovoltaic structures 5, the upper cylindrical portion 65 of each foot 26 of the photovoltaic structure 5 in lower position penetrates the lower frustoconical portion 66 of one of the feet 26 of the photovoltaic structure 5 in upper position.

[0066] Figure 7 is a partial, schematic perspective view of another embodiment of the foot 26. As with the foot 26 shown in Figure 4, the foot 26 illustrated in Figure 6 comprises the upper portion 65 and the lower portion 66. In the embodiment illustrated in Figure 7, the lower portion 66 comprises a lateral face 68 oriented outwards from the support 20, and the upper portion 65 comprises a lateral face 68 oriented outwards from the support 20. According to one embodiment, the faces 68 and 69 are flat and inclined with respect to the plane on which the frame 34 rests.

[0067] Figure 8 is a partial, schematic side view of a stack of two photovoltaic structures 5 as shown in Figures 1 and 2, and for which the feet 26 are as shown in Figure 7. The lateral face 68 of the lower portion 66 of each foot 26 of the photovoltaic structure 5 in the upper position abuts against the lateral face 69 of the upper portion 65 of one of the feet 26 of the photovoltaic structure 5 in the lower position.

[0068] Figure 9 is a partial, schematic perspective view of another embodiment of the foot 26. As with the foot 26 shown in Figure 6, the foot 26 illustrated in Figure 9 comprises the upper portion 65 and the lower portion 66. In the embodiment illustrated in Figure 9, the foot 26 further comprises a flat support plate 91 surrounding the base of the lower portion 66. The flat support plate 90 includes a through opening, not visible, so as not to obscure the lower portion 66. The support plates 90 are coplanar. When the photovoltaic structure 5 is placed on the surface, each flat support plate 90 rests against this surface. This advantageously allows for a better distribution of the weight of the photovoltaic structure 5 on the surface. The flat support plate 90 can be extended by a rim 91. As an example, the rim 91 can correspond to a flat plate orthogonal to the support plate 90.The rim 91 may include a through opening 92 which can be used to fix two adjacent photovoltaic structures 5 to each other using fixing means passing through the openings 92.

[0069] Figure 10 is a partial, schematic side view of a stack of two photovoltaic structures 5 as shown in Figures 1 and 2, and in which the feet 26 are as shown in Figure 9. The upper cylindrical portion 65 of each foot 26 of the photovoltaic structure 5 in the lower position penetrates the lower frustoconical portion 66 of one of the feet 26 of the photovoltaic structure 5 in the upper position.

[0070] Fig. 11 is a partial and schematic perspective view of another embodiment of a photovoltaic structure support 5.

[0071] The support 5 shown in [Fig.

[11] includes all the elements of support 5 shown in [Fig. 2] except that bars 36, 50, 52 are not present, that the reinforcing beams 54 are not present, that it also includes two bars 58, 59 each connecting bars 22 and 24, that each leg 16 has the structure shown in [Fig. 9], that the legs 16 are fixed to bars 30 and 32, that the transport guide 60 is replaced by two transport guides 60A, 60B arranged side by side, that the transport guide 62 is replaced by two transport guides 62A, 62B arranged side by side and fixed to bar 58, that it also includes two transport guides 60C, 60D arranged side by side and fixed to bar 32, and that it includes, in addition, two transport guides 62C, 62D arranged side by side and fixed to the bar 59.

[0072] The support 5 shown in [Fig. 11] advantageously has a reduced weight compared to the support 5 shown in [Fig.2].

[0073] Fig. 12 is a partial and schematic perspective view of another embodiment of a photovoltaic structure support 5.

[0074] The support 5 shown in [Fig. 11] includes all the elements of the support 5 shown in [Fig.2] except that the bars 38, 40, 44, and 48 are elongated.

[0075] Figure 13 is a cross-sectional view in a vertical plane containing the ninth bar 36 and perpendicular to the third and fourth bars 30, 32, illustrating the transport of the photovoltaic structure 5 by a transport tool, for example, a fork 70 of a forklift (not shown). The fork 70 enters the opening 61 of the first transport guide 60 and the opening 63 of the second transport guide 62, and is then actuated to lift the photovoltaic structure 5. The first transport guide 60 and the second transport guide 62 advantageously ensure proper positioning of the fork 70 relative to the support 20.

[0076] As an alternative, each transport guide 60, 62 can be replaced by two transport guides arranged side by side, as shown in Figures 11 and 12, and each intended to receive one of the arms of the fork 70.

[0077] Figure 14 is a partial, schematic perspective view illustrating the lifting of a stack of two photovoltaic structures 5 by a lifting tool 72. In one embodiment, the lifting tool 72 may include hooks 74, each hook 74 being connected to a cable or chain 76, the cables 76 being connected to the arm of a crane, not shown. In one embodiment, the lifting tool 72 includes as many hooks 74 as there are lifting rings 64 per photovoltaic structure 5. To lift the stack of two photovoltaic structures 5, the hooks 74 are inserted into the lifting rings 64 of the structure photovoltaic 5 located in the lower position in the stack and a pull is made on the cable 76. Several photovoltaic structures 5 can thus, advantageously, be lifted simultaneously.

[0078] According to one embodiment, the photovoltaic structure 5 is self-ballasted. This means that when the photovoltaic structure 5 is placed on a surface, for example a roof slab, it is not necessary to provide additional fastening means to ensure that the photovoltaic structure 5 remains fixed relative to the surface, as the weight of the photovoltaic structure 5 is sufficient to ensure that the photovoltaic structure 5 remains fixed relative to the surface under normal operating conditions. This advantageously simplifies the installation of the photovoltaic structure 5 on a surface.

[0079] According to one embodiment, when several photovoltaic structures 5 are placed on the same surface, the support 20 of a photovoltaic structure 5 can be connected to the support 20 of a neighboring photovoltaic structure 5 in order to improve the immobilization of the photovoltaic structures on the surface, for example under the effect of a strong wind.

[0080] Two embodiments will now be described in the case where the photovoltaic structure 5 is not totally self-ballasted.

[0081] Fig. 15 is a perspective view of part of the photovoltaic structure 5 of Fig. 1 and illustrates a method of fixing the photovoltaic structure 5 to a surface 80, for example a roof slab.

[0082] In this embodiment, a ballast 82 covers part of the third bar 30, the third bar 30 being interposed between the ballast 62 and the surface 80. Similarly, a ballast, not visible in [Fig. 14], can cover the fourth bar 32, the fourth bar 32 being interposed between the ballast and the surface 80. As an alternative, ballasts can be attached to each of the legs 26 or placed on each of the legs 26. In particular, when the legs 26 each have the structure shown in [Fig. 9], the ballasts can be placed on the bearing plates 90 of the legs 26.

[0083] Fig. 16 is a perspective view of part of the photovoltaic structure 5 of Fig. 1 and illustrates another way of fixing the photovoltaic structure 5 to a surface 80, for example a roof slab.

[0084] In this embodiment, the photovoltaic structure 5 is anchored to the slab 80 by fastening elements, including, for example, adhesive sheets or screwing means, for example, threaded rods 84. The bars 22 and 24 may include tabs 85 through which the threaded rods 84 pass. The slab 80 is covered with a thermally insulating layer 86, itself covered with a first waterproof layer 87, the threaded rods 84 passing completely through the thermally insulating layer 86 and the first waterproof layer 87. reach the slab 80. A second waterproof layer 88 can cover the legs 85 and the ends of the threaded rods 84.

[0085] Various embodiments and variations have been described. A person skilled in the art will understand that certain features of these various embodiments and variations could be combined, and other variations will become apparent to a person skilled in the art. In the embodiments described above,

[0086] Finally, the practical implementation of the embodiments and variants described is within the reach of a person skilled in the art, based on the functional indications given above.
