Description

Title of the invention: Photovoltaic panel structure comprising a photovoltaic panel orientation adjustment device. technical field

[0001] The present invention relates to the field of photovoltaic panels or solar panels, and more particularly to a photovoltaic panel support structure that allows the tilt of the photovoltaic panel to be adjusted in order to make the best use of sunlight at various times of the year, for example, throughout the four seasons, and / or to be installed on various supports with different tilt angles, such as on a wall, on the ground, or on a roof. The present invention also relates to a photovoltaic installation comprising this type of support structure and a photovoltaic panel. Technological background

[0002] A photovoltaic panel is used to convert solar energy into electricity. It is composed of photovoltaic cells that capture photons from sunlight and generate an electric current through the photovoltaic effect. This electricity can then be used to power electrical appliances, stored in batteries for later use, or fed into the electrical grid. Photovoltaic panels are a sustainable and renewable solution for producing energy, thus reducing dependence on fossil fuels and greenhouse gas emissions.

[0003] The orientation of photovoltaic panels is crucial for maximizing their efficiency. To capture the maximum amount of sunlight throughout the day, the panels must be optimally oriented with respect to the sun's path. In the Northern Hemisphere, this generally means a southward orientation, as this allows the panels to receive the most direct sunlight possible. The tilt of the panels, which depends on the latitude, must also be adjusted to optimize the angle of incidence of the sun's rays, thus maximizing electricity production.

[0004] The importance of this orientation is linked to the fact that the amount of solar energy captured varies with the angle and position of the sun in the sky. Poor orientation or tilt of the panels can significantly reduce their energy yield, as they will not receive enough direct sunlight. By optimizing the orientation and tilt of the photovoltaic panel, maximum absorption of solar energy is ensured throughout the year, including during seasons when the sun is stronger. low in the sky. This ensures stable and efficient electricity production, making the installation of photovoltaic panels more efficient and profitable.

[0005] Photovoltaic panels can be installed on different types of surfaces, each with its own characteristics in terms of tilt. Therefore, different installation scenarios must be considered for a photovoltaic panel depending on the type of surface on which it is installed.

[0006] A photovoltaic panel is, for example, installed on one of the mounting surfaces listed below, the mounting surface having a specific angle relative to the ground:

[0007] • A pitched roof, this type of installation being common in residential buildings and often Well-suited for photovoltaic installations. The roof pitch largely determines the panel orientation. Generally, pitched roofs have a slope of 15 to 45 degrees. The optimal angle for the panels is close to the roof pitch, often adjusted slightly to optimize production according to latitude.

[0008] • A flat roof, used for example for commercial, industrial and for residential buildings. On these flat roofs, the panels are usually mounted on structures that tilt them at approximately 10 to 15 degrees.

[0009] • Directly on the ground, for example for photovoltaic power plants, generally installed in undeveloped areas, industrial wastelands or on agricultural land. The panels are mounted on inclined structures generally between 20 and 30 degrees, depending on the latitude and local conditions.

[0010] • On building facades, the panels being, for example, directly integrated in building facades. The surface area is then often vertical or close to vertical (90 degrees). This configuration is less optimal in terms of energy production compared to roofs, but it can be useful in high-density urban areas.

[0011] • On transport infrastructure such as bridges, tunnels, subway stations or train. The inclination of the landing surface varies depending on the specific structure.

[0012] The optimal tilt of a photovoltaic panel relative to a horizontal plane also depends on the latitude at which the photovoltaic panel is installed. Therefore, the optimal orientation of a photovoltaic panel according to its latitude follows these recommendations: • a tilt angle of the photovoltaic panel of 10 to 20° for a low latitude, i.e. between 0 and 23.5°; • an angle of inclination of the photovoltaic panel close to the inclination of the latitude of the installation site for a latitude between 23.5 and 50°; • a tilt angle of the photovoltaic panel greater than the tilt of the latitude of the installation site for a latitude greater than 50°, so as to maximize the exposure of the photovoltaic panel during the winter months when the sun is low on the horizon.

[0013] It is therefore essential to follow these recommended tilt angles to optimize the efficiency of a photovoltaic panel, regardless of the surface area. Additionally, the orientation of the photovoltaic panel should be adjusted according to the seasons.

[0014] Photovoltaic panel support structures described in the following documents are known: FR3112912; US9166525; CN214315144; CN209389991; US2024 / 0007043; CN113595486; CN112046326; FR3079090; US8176693; FR3056363; US9553544; and CN115913077. These photovoltaic panel support structures comprise a base that is fixed to a receiving surface, for example one of those mentioned above, and a movable frame that pivots relative to the base, and an adjustment device for fixing the movable frame relative to the base in two or more angular positions. Summary of the present invention

[0015] The present invention overcomes the technological background problems described above by designing a photovoltaic panel support structure that allows a photovoltaic panel to be mounted on different types of supports with varying orientations, while also allowing optimal adjustment of the photovoltaic panel's tilt relative to the vertical, thus enabling optimal use of the photovoltaic panel. Compared to existing solutions described in the aforementioned prior art documents, the photovoltaic panel support structure is intended to be simple in design, easy to use, and easily adaptable to allow modification of the angular position between the base and the mobile frame in more than two positions.

[0016] To this end, the invention relates firstly to a photovoltaic panel support structure, which comprises: - a base defining a reference plane, the base being configured to be mounted on a receiving surface; - a mobile frame defining an assembly plan, the mobile frame being configured to accommodate the photovoltaic panel; - a first pivot joint arranged between the mobile frame and the base to mount the mobile frame in rotation around a first axis on the base, the first axis being parallel to the reference and mounting planes; and - a locking device arranged between the mobile frame and the base, the locking device being configured to stabilize the mobile frame relative to the base according to at least two defined angular positions between the reference plane and the mounting plane. Furthermore, according to the invention, the locking device comprises: - a stabilizing system including a first interface for connection with the mobile frame and a second interface for connection with the base, the first and second interfaces being separated by a length defining one of at least two angular positions, the stabilizing system being configured to modify said length to select one or the other of the at least two angular positions, - a first locking member attached to the base and including a second connection element distant from the first axis and configured to receive the second interface; - a second locking member, a link being arranged between the second locking member and the first locking member to move the second locking member into a locked position or into an unlocked position, the second locking member being configured to: • in the locked position, block the second interface in the second receiving connection element, and • in the unlocked position, release said second interface from the second receiving connection element.

[0017] Such a structure allows the orientation of the photovoltaic panel to be adjusted for any surface, the receiving surface defining the surface of the support to which the base is fixed. The locking device allows the structure to be secured in different adjustment positions, thus preventing any unintended change in the tilt angle of the photovoltaic panel, which is defined by the angle formed between the reference plane and the mounting plane.

[0018] According to a first advantageous embodiment of the structure, the stabilizing system comprises at least two elongated stabilizing members, the first interface comprising a pivot joint mounting of the stabilizing members on the mobile frame along second axes parallel to the first axis, each stabilizing member comprising at a distal end of the second axis associated with it a first connection element corresponding to the second interface, each distance separating a second axis from a first connection element associated with a stabilizing member being unique, the length defining one of the at least two angular positions being defined by one of the distances along the first connection element received by the second connection element.

[0019] The plurality of stabilizing organs allows a user to easily adjust the angle of inclination by selecting one of the stabilizing organs according to its length defined by the distance separating the second axis associated with this stabilizing organ from the first connection element associated with this same stabilizing organ.

[0020] According to a second advantageous embodiment of the structure, the stabilizing system comprises a stabilizing member of elongated shape and configured to vary its elongation, the first interface comprising a pivot joint mounting of the stabilizing member on the mobile frame along a second axis parallel to the first axis, the stabilizing member comprising at a distal end of the second axis a first connecting element corresponding to the second interface, the length defining one of the at least two angular positions being defined by a distance separating the second axis from the first connecting element, the distance being a function of the elongation.

[0021] A user is thus able to easily adjust the tilt by playing on the length of the stabilizing member, increasing the tilt for example when increasing the length of the stabilizing member or lengthening it and conversely, decreasing the tilt when decreasing the length of the stabilizing member or shortening it.

[0022] According to an advantageous embodiment, the mobile frame comprises a third connecting element, which is configured to insert into the second connecting element when the reference and mounting planes form a minimal angle, the third connecting element being locked in the second connecting element when the second locking member is in the locked position and free to be removed from the second connecting element when the second locking member is in the unlocked position.

[0023] The third connection element thus allows for an additional orientation of the photovoltaic panel in which the reference and mounting planes are as close as possible, or even parallel. This configuration makes it easier to transport the structure, as it is then in a folded position, while maintaining it in this position, preventing any risk of opening the angle formed between the reference plane and the mounting plane, as well as any risk of collision between different elements of the structure. Furthermore, such a construction allows for the sharing of a structural element, in this case the second connection element, which can receive either the first or the third connection element.

[0024] According to an advantageous embodiment, the second locking member includes a pull tab configured to allow manipulation of the second locking member by a user. The pull tab thus allows the user to easily move the second locking member in order to lock or release the first and / or third connecting element during an operation to adjust the tilt of the photovoltaic panel.

[0025] According to a preferred embodiment of the structure that is the object of the invention, the first locking member defines a third axis not parallel to the first axis. Furthermore, the connection between the second locking member and the first locking member is a sliding joint configured to translate said second locking member along the third axis into the locked or unlocked position. An alternative embodiment remains possible, however, with a pivot joint configured to pivot said second locking member, about a pivot axis, into the locked or unlocked position.

[0026] Preferably, according to this preferred embodiment, the third axis is parallel to the reference plane and normal to the first axis.

[0027] Preferably, according to this preferred embodiment, the first locking member comprises a profile extending longitudinally along the third axis, the second connecting element comprising a notch, the first connecting element comprising a rod configured to engage in the notch, the second locking member comprising a latch extending along the third axis and mounted as a slide along the third axis relative to the profile, the latch comprising a finger configured to lock the rod in the notch in the locked position. Such elements can thus be made using various components such as sheet metal and / or profiles, thereby enabling high-volume, industrialized production of elements that are both reproducible and cost-effective.

[0028] According to an advantageous embodiment, the structure includes a return element configured to bring the second locking member to the locked position. Thus, when the user has finished adjusting the tilt of the photovoltaic panel by adjusting the angle between the base and the mobile frame, the lock is again effective without any further operation, the second locking member automatically returning to the locked position.

[0029] According to an advantageous embodiment, the stabilizing element(s) are each formed from a rod with a circular cross-section. Such a rod is particularly easy to manufacture and economical.

[0030] According to an advantageous embodiment, the base comprises openings leading to a bearing surface, the bearing surface being parallel to the reference plane, the openings being configured to allow the passage of fastening elements. The base can thus be fixed securely to the receiving surface, for example by means of screws or bolts.

[0031] According to an advantageous embodiment, the structure includes a ballast element configured to be attached to the base. The ballast element then allows the structure to be placed on the ground without the use of any fasteners that could damage the surface. The structure is thus easily movable.

[0032] According to an advantageous embodiment, the structure comprises at least one retaining element arranged on a rear face of the photovoltaic panel, this at least one retaining element being configured to hold a stabilizing member in a plane parallel to the foreground by receiving a first connection element not received in the second connection element. Thus, the unused stabilizing member(s) are held in a predetermined position, facilitating both the transport of the structure and the handling of one of the stabilizing members, the other stabilizing members being held, where applicable, outside the handling area of ​​the stabilizing member received in the second connection element.

[0033] According to an advantageous embodiment, the base comprises at least one fourth connecting element and the mobile frame comprises at least one fifth connecting element, the at least fourth and fifth connecting elements being complementary and configured to removably mount and lock the mobile frame onto the base, thus constituting the first pivot joint along the first axis during said mounting. Such a construction allows the structure to be assembled by the user and disassembled to facilitate transport. Other embodiments could be envisaged with a permanent pivot joint along the first axis between the mobile frame and the base, in which case the mobile frame and the base would remain connected to each other at the first pivot joint.

[0034] The invention also relates to a photovoltaic installation comprising the structure according to any one of the embodiments previously stated and a photovoltaic panel fixed to the mobile frame.

[0035] According to an advantageous embodiment, the photovoltaic installation includes an inverter electrically connected to the photovoltaic panel. The inverter is then sized according to, in particular, the electrical characteristics of the photovoltaic panel.

[0036] Thus, thanks to all the functional and structural technical characteristics of the present invention, we have a photovoltaic panel support structure, or even a photovoltaic installation, which is solid, suitable for installation on different surfaces with varying inclinations and easy to handle, allowing the inclination of the photovoltaic panel to be adjusted optimally regardless of the season.

Description of examples of achievements

[0038] Examples of photovoltaic installations will now be described with reference to Figures 1 to 9. Figures 1 to 9 present a photovoltaic installation according to a first embodiment, which is defined by a number of stabilizing elements greater than or equal to two, while Figures 10 to 12 present a photovoltaic installation according to a second embodiment, which is defined by a stabilizing element with variable or extensible geometry.

[0039] Figures 1 and 2 represent perspective views of a photovoltaic installation comprising a photovoltaic panel support structure according to the present invention in an open configuration and according to a first embodiment.

[0040] The photovoltaic panel support structure 1 comprises a base 10 defining a reference plane PO, the base 10 being configured to be mounted on a mounting surface (not shown) whose inclination with respect to a vertical axis can be varied, the mounting surface being a support such as the ground, a terrace, a vertical wall, a sloping wall, a sloping roof or a flat roof. To this end, the base 10 comprises, as illustrated in [Fig. 1], openings 104 leading to a bearing surface 103 allowing the passage of fasteners such as screws or bolts for fixing to the support, the bearing surface 103 under the base 10 bearing against the mounting surface. The reference plane PO is then defined by the support surface 103. It should be noted that other means of fixing are also conceivable such as, for example, flanges allowing the base 10 to be pressed against the support.The base 10 can consist of several pieces, assembled together or not and fixed to the receiving surface, or of a single piece fixed to the receiving surface.

[0041] The base 10 further comprises means for receiving a movable frame 11, which is configured to receive a photovoltaic panel 100 and defines a mounting plane PI, the mounting plane PI being, for example, coincident with the functional surface of the photovoltaic panel, i.e., the surface along which photovoltaic cells are arranged, or a mean plane corresponding to this surface if the latter is not flat. According to a particular embodiment, openings 108 illustrated in Figures 4 and 5 are made in two distinct locations so as to receive respectively a first hinge 11b and a second hinge 11 arranged on the movable frame 11 to form a pivot joint between the base 10 and the movable frame 11, the relative position of the two openings 108 defining a first axis Al of rotation of the movable frame 11 around the base 10.The base 10 includes, for example, a part extending longitudinally and connecting the two openings 108, [Fig.1] representing in particular this part as a U, the openings 108 being made in the folded parts of this U. These openings 108 are preferably in the form of notches. In particular, fins 106 are arranged on the base 10 and mounted in translation on the latter by means of, for example, two pins inserted in oblong-shaped housings, so as to close the openings 108, thus allowing the first and second hinges 11b, 11c to be locked in the openings 108 once the mobile frame is assembled on the base 10. Optionally, return elements such as springs 107 are positioned between the base 10 and each fin 106 in order to return each fin 106 to its locking position, thus ensuring that the first and second hinges 11b, 11c are held securely in position.The first and second hinges 11b, 1 are here additional elements mounted on the movable frame 11, for example fixed by crimping or screwing. Thus, the base 10 comprises two. Fourth connecting elements, each comprising a fin 106, a spring 107, and an opening 108 in the base 10, and the mobile frame 11, comprise two fifth connecting elements, each comprising a hinge 11b, 11c. The fourth and fifth connecting elements are complementary and configured to removably mount and lock the mobile frame 11 onto the base 10, forming the first pivot joint along the first axis A1 during assembly. According to other embodiments, it is possible to make them as a single element, or to integrate them directly into the main body of the mobile frame 11, for example, by machining or by using a main body of the mobile frame 11 made of a thermoplastic material and obtained by molding.

[0042] Thus, the base 10 includes two fourth connection elements consisting of sub-assemblies comprising the fins 106, the springs 107 and the openings 108 and the mobile frame 11 includes two fifth connection elements respectively consisting of the first hinge 11b and the second hinge 11, these fourth and fifth connection elements being complementary and configured to mount and removably lock the mobile frame 11 onto the base 10 by constituting the first pivot connection along the first axis Al during the assembly of the structure 1.

[0043] According to this example, the mobile frame 11 includes a frame 1a, which is configured to receive a photovoltaic panel 100. In an alternative embodiment, this frame 1la can be an integral part of the photovoltaic panel 100. The frame 1la has, for example, a receiving surface suitable for supporting the rear face 1001 of the photovoltaic panel 100. It should be noted that the functional surface of the photovoltaic panel 100, i.e., the surface comprising the photovoltaic cells, is the upper face of the photovoltaic panel 100, i.e., the face opposite the rear face 1001 of the photovoltaic panel 100. The frame 1la is, for example, made from metal angle brackets, which are butted, welded, or bent at several points corresponding to the corners of the frame 1a, at right angles.

[0044] It should be noted that the first axis Al is parallel to both the datum plane PO and the mounting plane PL. The rotation of the mobile frame 11 relative to the base 10 around this first axis Al has the effect of linearly varying the angle between the datum plane PO and the mounting plane PL. In order to regulate or adjust this angle between these two planes, a locking device is arranged between the mobile frame 11 and the base 10, the locking device being configured to stabilize the mobile frame 11 relative to the base 10 in at least two defined angular positions between the datum plane PO and the mounting plane PL.

[0045] The locking device includes, in particular, a stabilizing system 120 configured to hold the movable frame 11 in different positions relative to the base 10. The stabilizing system thus includes a first interface for connection with the mobile frame 11 and a second interface for connection with the base 10, the first and second interfaces being separated by a length defining one of the at least two angular positions, the stabilizing system 120 being configured to modify the length to select one or the other of the at least two angular positions.

[0046] According to the first embodiment, the stabilizing system 120 of the locking device comprises at least two elongated stabilizing elements 12, of which there are three in this particular embodiment. It should be noted, however, that the invention is not limited to a photovoltaic panel support structure 1 comprising three stabilizing elements; the number of stabilizing elements is defined, for example, so as to offer a maximum of possible adjustments while maintaining an affordable and lightweight product. The number of stabilizing elements can thus be 2, 3, 4, 5, or more than 5 in this first embodiment. However, it is necessary to ensure technical feasibility for a large number of rods, as sufficient space must be available in the frame 1 to accommodate elements receiving these stabilizing elements 12.

[0047] To this end, the stabilizing elements 12 are connected to the frame 1la by their ends 12a, 12b, which, according to the example illustrated in [Fig. 3] representing an exploded view of the photovoltaic installation 1, are cylindrical and fit into openings 111a, 111b arranged in the frame 1la so as to create a pivot-type connection between each stabilizing element 12 and the movable frame 11, thus corresponding to the first interface. Each stabilizing element 12 is therefore mounted for rotation about a second axis A2 on the movable frame 11, each second axis A2 being associated with a stabilizing element 12.The orifices 111a, 111b arranged in the frame lia so as to obtain a pair of orifices 111a, 111b arranged at the same distance from the first axis Al, each orifice 111a, 111b of this pair of orifices receiving a distinct end 12a, 12b of the same stabilizing member 12 so as to dispose the second axis A2 associated with the stabilizing member 12 parallel to the first axis AL.

[0048] According to other embodiments, the connection between a stabilizing member 12 and the mobile frame 11 is made using additional parts, for example using shoes, hinges or bearings.

[0049] The orifices 111a, 111b are distant from the first axis A1 and, preferably, as far away from the first axis A1 as possible in order to obtain a large distance separating a second axis A2 from the first axis A1. Thus, according to the illustrated example, the orifices 111a, 111b are positioned on a part of the distal frame A1 of the first axis A1. These orifices are, in particular, aligned and regularly spaced so as to define the second axes A2 parallel and coplanar, with a constant distance separating two consecutive second axes A2.

[0050] Each stabilizing member 12 describes a V-shape whose extremities correspond to the previously presented extremities 12a, 12b and whose distal central portion of these extremities, and therefore of the second axis A2, defines a first connecting element 121 corresponding to the second interface. Each stabilizing member 12 is of a different size and, according to the example illustrated in Figures 1 to 3, the width of a stabilizing member, i.e. the distance separating its two extremities 12a, 12b, is equal for assembly reasons with the frame 1a, which has flat and parallel parts on which are arranged the openings 111a, 111b receiving the extremities 12a, 12b of the stabilizing member.The height of each stabilizing element 12 is different; that is, the distance between the second axis A2 associated with a stabilizing element 12 and the first connecting element 121 of that stabilizing element 12 varies from one stabilizing element 12 to another. By assembling the stabilizing elements 12 from largest to smallest, moving away from the first axis A1, we obtain stabilizing elements 12 mounted in series from smallest to largest, which can rotate freely around their axis of rotation, the second axis A2. Indeed, by arranging them in this way, the stabilizing elements 12 do not collide with each other.

[0051] According to another particular embodiment not shown, the stabilizing members 12 have different widths and are, for example, mounted for rotation about the same second axis A2. In other words, the second axes A2 associated with the different stabilizing members coincide. The connection between the stabilizing members 12 and the movable frame 11 is then achieved using additional elements, for example, a single shaft having the second axis A2 as its axis and on which hollow cylinders connected to the ends of the stabilizing members 12 are mounted. In other words, the stabilizing members 12 are connected to the movable frame 11 via coaxial bearings arranged along the second axis A2.

[0052] The positions of the ports 111a, 111b, as well as the heights of the stabilizing elements 12, are important. Indeed, the main constraint is to obtain parallel axes A1 and A2 and to allow adjustment of the angle of inclination of the mounting plane PI relative to the reference plane PO. As illustrated in [Fig. 2], this angle, denoted a, varies according to: • the relative position of the hinges 11b, 1 on the base 10, therefore the position of the first axis Al, • the relative position of the holes 111a, 111b on the upright of the movable frame 11, therefore the position of the second axis A2 with respect to the first axis Al, a first length Li separating the first axis Al from the second axis A2, a plurality of positions being defined by the plurality of stabilizing organs 12, that is to say that the first length Li is different for each stabilizing organ 12 considered, • of a height of the stabilizing organ 12 considered, this second length being denoted L2, and corresponding to the distance separating the second axis A2 from a fourth axis A4 associated with the first connecting element 121 of the stabilizing organ 12 considered, this distance being unique and different according to each stabilizing organ 12, and • of a position of the first connection element 121 of the stabilizer organ 12 considered, the distance between this position corresponding to the position of the fourth axis A4 and that of the first axis Al, this third length being noted L3.

[0053] Thus, to define the angle of inclination a of the mounting plane PI with respect to the reference plane PO, it is necessary to select a stabilizing member 12, which defines the first and second lengths Li and L2, and then to know the third length L3.

[0054] To this end, the distal end of the stabilizing member 12 of the second axis A2, here constituted by the middle part of the stabilizing member 12, includes a first connecting element 121. In order to position this end relative to the base 10 and thus to define the angle α between the reference planes PO and mounting plane PI associated with this stabilizing member 12, a first locking member 101 integral with the base 10 includes a second connecting element 102, complementary to the first connecting elements 121, arranged at a distance from the axis Al, this distance corresponding to the third length L3, and configured to receive a first connecting element 121 from among the set of the first connecting elements 121 associated with the stabilizing members 12. The third length L3 is in particular defined along a third axis A3 normal to the first axis Al and parallel to the reference plane PO.

[0055] In other words, the first locking member 101 attached to the base 10 extends along the third axis A3 not parallel to the first axis Al and includes a second connection element 102 complementary to the first connection elements 121 and configured to receive either of the first connection elements 121.

[0056] Depending on the stabilizing member 12 used, i.e., depending on the first connecting element 121 positioned within the second connecting element 102, the angle α between the reference plane PO and the mounting plane PI varies. For each stabilizing member 12 used, a configuration is defined, each configuration having a different angle α. According to this particular embodiment, the value of the angle α is, for example, equal to: • 0° when none of the stabilizing elements 12 are used, i.e. when the reference planes PO and mounting plane PI are parallel, this position corresponding to a “folded configuration”, • 30° when the shortest stabilizing member 12 is used, • 45° when the intermediate-sized stabilizing member 12 is used, • 60° when the longest stabilizing member 12 is used. Obviously, other angle values ​​are conceivable by adjusting one of the three lengths L1, L2, L3 and the number of these values ​​is adjustable by changing the number of stabilizing organs 12. The positions for which the value of angle a is non-zero correspond to "open configurations".

[0057] Thus, according to the particular embodiment illustrated in [Fig.1] representative of the first embodiment, the photovoltaic installation has four possible tilt settings, three of which are defined according to the stabilizing element 12 used, i.e. according to the first connection element 121 selected from the plurality of first connection elements 121 and engaged in the second connection element 102.

[0058] Figures 10 to 12 illustrate a second embodiment, in which the photovoltaic panel support structure 1 includes a single stabilizing element 12, still elongated in shape, configured to vary its elongation.

[0059] The first interface then comprises a pivot joint mounting of the stabilizing member 12 on the movable frame 11 along a single second axis A2 parallel to the first axis A1, while the stabilizing member 12 comprises, at a distal end of the second axis A2, a first connecting element 121 corresponding to the second interface. It should be noted that the first connecting element 121 is similar to a first connecting element presented according to the first embodiment. The length defining one of the at least two angular positions is then defined by a distance separating the second axis A2 from the first connecting element 121, this distance being a function of the elongation of the stabilizing member 12, which has a variable geometry.

[0060] According to the particular embodiment illustrated in Figures 10 to 12, the stabilizing member 12 comprises a V-shaped rod, its middle portion corresponding to the first connecting element 121 extending along a fourth axis A4 parallel to the first and second axes A1 and A2, and flanked on either side by the ends 122a extending symmetrically in different directions from the fourth axis A4. The two ends 122a are inserted into tubes 122b, thus forming a sliding joint or a sliding pivot joint when the rod and the tubes 122b have a circular cross-section. Indeed, the outer diameter of the rod, and therefore of the ends 122a is notably smaller than the inner diameter of the tubes 122b so as to allow the ends 122a to slide freely within the tubes 122b. The subassemblies comprising an end 122a and a tube 122b thus form jacks of variable length. Each tube is assembled onto the frame 1la of the mobile frame 11 by means of pivots 123 or ball joints and shoes 124 fixed to the frame 1la. Note that the rod is relatively flexible between the first connecting element 121 and each end 122a when the ends 122a do not extend along an axis normal to the fourth axis A4, so as to accommodate deformation of the rod during the sliding of the ends 122a within the tubes 122b. Indeed, when a user changes the tilt angle of the photovoltaic panel 100 relative to the base 10, the angle between the ends 122a opens and closes as illustrated.It would also be possible to consider a first connection element 121 of variable width in order to compensate for the lengthening or narrowing of the stabilizing member 12, when the two ends 122a of the rod slide relative to the tubes 122b. .

[0061] In order to lock the angular position between the base 10 and the movable frame 11, i.e. the relative position of the mounting plane PI with respect to the reference plane PO, the relative movement of the ends 122a with respect to the tubes 122b corresponding to the sliding of the ends 122a in the tubes 122b is stopped by any means known to those skilled in the art, for example by: - a locking mechanism achieved by rotating the tube 122b or the rod 122a around its axis, using appropriate joints of the moving part, one or more cams positioned between the tube 122b and the end 122a of the rod clamping the two elements together, or - a compression element for the tube 122b such as a clamping lever or a mandrel, or - the insertion of pins passing through open orifices arranged opposite each other in the ends 122a and the tubes 122b, each tube 122b or each end 122a then comprising several orifices allowing to define several elongations of the stabilizing system 120, - a spring-loaded strip associated with a push button arranged on each tube 122b, or - a valve or safety valve allowing the air to be trapped in the chamber of the cylinder thus formed, a sealing gasket being arranged for example at the inlet of each tube 122b so as to fit the external surface of the end 122a of the rod to make the chamber of the cylinder airtight, the sliding of the rod in the tube 122b drawing in or expelling the air contained in this chamber when the valve is open and this same sliding being impossible when the valve maintains a constant volume of air in the chamber.

[0062] According to the specific embodiments illustrated in Figures 1 to 3 and in Figures 10 and 11, the first locking member 101 consists of a profile Partially U-shaped, open at the top and extending longitudinally along the third axis A3, the second connecting element 102 consists of notches arranged on the two vertical surfaces of the U at the same distance from the first axis A1; that is, the notches are identical in shape and are arranged to face each other, thus precisely defining the fourth axis A4 passing through them. Each stabilizing member 12 is a rod with a circular cross-section, consisting of a rod with a more or less V-shaped profile and a flattened apex in its middle section. This middle section constitutes the first connecting element 121 and is configured to engage in the notches of the second connecting element 102.

[0063] It should be noted that the notches of the second connecting element 102 are, according to these examples, made directly in the main body of the first locking member 101. However, it is possible, according to other embodiments, to provide a second connecting element 102 added to the main body of the first locking member 101, this second connecting element 102 being, for example, fixed to the main body of the first locking member 101 by screwing or crimping, thus saving material during the manufacture of the base 10 while allowing great flexibility in the realization of different variants of the photovoltaic installation.

[0064] In order to hold a first connecting element 121 within the second connecting element 102, the locking device includes a second locking member 13 positioned relative to the first locking member 101 to form a sliding connection between the second locking member 13 and the first locking member 101. The second locking member 13 then translates along the third axis A3, its stroke being defined between a locked position and an unlocked position. The second locking member 13 is thus configured to: • in the locked position, lock the first connecting element 121 into the second connecting element 102 receiving it, and • in the unlocked position, release the first connection element 121 from the second connection element 102 receiving it.

[0065] As illustrated in Figures 6 and 7, the second locking member 13 comprises A latch or lock extending along the third axis A3 and mounted in a slide along the third axis A3 relative to the profile, the latch comprising two fingers 132 (only one of which is visible in the cross-sectional view) configured to lock the rod in the notch in the locked position at the level of the first connecting element 121 extending along the fourth axis A4. Thanks to the second locking member in the locked position, it is not possible to disengage the first connecting element 121 from the second connecting element 102 in which it is engaged, even by applying force. traction force on the first connecting element 121, for example directly via the stabilizing member 12 or indirectly by moving the mobile frame 11 away from the first locking member 101. Thus, neither gravity nor wind, for example, are able to disengage the first connecting element 121 from the second connecting element 102 and thus change the tilt angle of the photovoltaic panel 100 mounted on the mobile frame 11.

[0066] The sliding connection is made by axes 131 attached to the second locking member 13 moving in oblong openings 105 made in the first locking member 101 and extending along the third axis A3.

[0067] In order to slide or translate the second locking member 13 along the third axis A3, the second locking member includes a pull tab 133 configured to allow manipulation of the second locking member 13 by a user.

[0068] To prevent any unwanted movement of the second locking member 13 relative to the first locking member 101, a return element 14 is optionally added. This return element 14 serves to maintain the second locking member 13 in the locked position and to move the second locking member 13 towards the locked position. The return element 14 consists of a tension spring attached on one side to a first rod 109 fixed to the first locking member 101 and on the other side to a second rod corresponding to one of the axes 131 fixed to the second locking member 13. The transition of the second locking member 13 from the unlocked to the locked position occurs automatically without user intervention.

[0069] As illustrated in Figures 1 to 3, 11 and 12, the structure 1 includes retaining elements 1002 arranged on the rear face 1001 of the mobile frame 11 or the photovoltaic panel 100. These retaining elements 1002 are configured to hold stabilizing members 12 in a plane parallel to the mounting plane PI by receiving the first connection elements 121 not received in the second connection element 102. In other words, the structure 1 includes as many supports 1002 as stabilizing members 12, these retaining elements 1002 each receiving an unused stabilizing member 12, i.e. not used to orient the mounting plane PI with respect to the reference plane PO. These retaining elements 1002, in the form of elastic hooks, thus receive a first connecting element 121 inserted by force into a retaining element 1002 when this first connecting element 121 is not received by the second connecting element 102.A stabilizing member 12 whose first connecting element 121 is inserted into or received by a retaining element 1002 is then subjected to the movable frame 11, the stabilizing member being anchored on one side. within the framework of the mobile frame 11 and on the other side immobilized in relation to the photovoltaic panel 100 also fixed to the mobile frame 11.

[0070] Thanks to these retaining elements 1002, the stabilizing members 12 are kept away from the photovoltaic panel 100 so as to avoid any collision between the stabilizing member 12 and the photovoltaic panel 100.

[0071] Figures 6 and 7 represent part of the locking device of a photovoltaic installation according to the present invention in a folded configuration, according to a particular embodiment, which is representative of the first embodiment but whose principle is also applicable to the second embodiment.

[0072] The mobile frame 11 includes a third connecting element 112, which is configured to insert into the second connecting element 102 when the reference planes PO and PI form a minimal angle α, i.e., when the second connecting element 102 receives the third connecting element 112 in the previously described folded configuration. The third connecting element 112 is then locked into the second connecting element 102 when the second locking member 13 is in the locked position and free to be removed from the second connecting element 102 when the second locking member 13 is in the unlocked position.

[0073] This technical solution has the advantage of sharing the second locking element 102 for all configurations, the second locking element 102 being used in both the open and folded configurations. For this to work, it is necessary, for example, to make the third connecting element 112 so as to obtain the same functional surfaces as those of the first connecting element 121, for example by making a rod of the same outside diameter and of sufficient width to fit into the notches.

[0074] Thus, the folded configuration corresponds to an ideal configuration for transporting the photovoltaic installation, as it is in a compact folded configuration and its various elements are immobilized relative to each other. Keeping the stabilizing element 12 away from the photovoltaic panel 100 prevents damage to the photovoltaic panel 100 in the event of any impacts between the latter and the stabilizing element 12, which is important because the rear face 1001 of the photovoltaic panel is often very fragile, while the mobile frame 11 is immobilized relative to the base 10 by means of the second locking element 102 attached to the base 10, which receives the third connection element 112 attached to the mobile frame 11.

[0075] This folded configuration is also particularly suitable for withstanding inclement weather, especially in the event of strong winds, the 100 photovoltaic panel being thus brought as close as possible to the reception area on which structure 1 is installed in order to limit its wind resistance.

[0076] Optionally, in order to be able to place the solar installation on the ground for example, without fixing it to the support, a ballast element 17 is added to the structure 1.

[0077] Figure 8 shows a perspective view of the photovoltaic installation of the [Fig. 1] comprising such a ballast element 17. The ballast element 17 is specifically configured to conform to the shape of the base 10 of the structure 1 and enclose it. The base 10 is thus positioned between the ground or the receiving surface and the ballast element 17. The ballast element 17 is, for example, made of a high-density solid material, such as metal, concrete, or a high-density composite. In other variants, it consists of a casing filled with another material, such as water or sand, allowing a photovoltaic system installer to easily transport the empty, and therefore lightweight, ballast element 17 and then fill it with this other material once installed.

[0078] Figure 9 shows a bottom view of the ballast element 17 of Figure 8, according to An example of a particular implementation. The ballast element 17 includes pads 174 positioned on its rear face, which allow, for example, runoff water to pass under the ballast element 17 via grooves 172. The number and arrangement of the pads 174 is determined so as, for example, to avoid damaging or puncturing a second support on which the ballast element 17 is placed, for example to avoid perforating a waterproofing membrane laid on a roof terrace.

[0079] Incidentally, the grooves 172 allow the passage of an electrical cable, which allows the photovoltaic installation to be electrically connected to an electrical network.

[0080] Second grooves 173 allow the insertion of the base 10 between the pads 174, the second grooves 173 thus conforming to the external surfaces of the base 10, the depth of these second grooves 173 being defined for example so as to minimize a functional gap between the receiving surface receiving both the base 10 and the ballast element 17, corresponding in particular to the bearing surface 103, and the upper surface of the base 10 opposite the bearing surface 103, this distance corresponding according to this example to the thickness of the profile.

[0081] According to another variant not illustrated, the rear face of the ballast element 17 does not include the grooves 172 so as to maximize the bearing surface of the ballast element 17 on a support.

[0082] The ballast element 17 also includes a cavity 171, which is designed to allow the insertion of an inverter 200, which is visible in Figures 1 to 3. Indeed, according to the particular embodiment illustrated in particular in [Fig. 1], the photovoltaic installation comprises the structure 1, a photovoltaic panel 100 fixed to the mobile frame 11 of structure 1 and an inverter 200 electrically connected to the photovoltaic panel 100, for example via a junction box (not shown).

[0083] The junction box is for example glued to the rear face 1001 of the photovoltaic panel 100, is connected in input to the photovoltaic cells of the photovoltaic panel 100 and is connected in output to the inverter 200 via two electrical wires, the two electrical wires being traversed by a direct current when the photovoltaic panel receives solar radiation on its functional surface provided with photovoltaic cells.

[0084] The inverter 200 is, for example, a micro-inverter, configured to be connected to the photovoltaic panel 100 via the junction box. Optionally, the inverter 200 is also connected to other photovoltaic installations of the same type, the latter not having an inverter 200, the inverter 200 being shared for several juxtaposed photovoltaic installations, for example.

[0085] The inverter 200 is for example fixed to the base 10 by means of fixing elements, for example via holes allowing the passage of fixing screws for example, the holes being made in the base 10 (not shown).

[0086] Such a photovoltaic installation is thus easy to install on various supports with different inclinations. The inclination of the photovoltaic panel in this installation is then easily adjustable, an angle between a reference plane associated with the base of the photovoltaic panel support structure and a mounting plane of the photovoltaic panel being defined by means of a simple, intuitive, and safe adjustment mechanism. A user is thus able to place such a photovoltaic installation on a suitable support and adapt the photovoltaic panel support structure to ideally adjust the inclination of the photovoltaic panel according to the season, for example.

[0087] The invention is not limited, however, to the configurations and embodiments described above, but extends to any photovoltaic installation equipped with a photovoltaic panel support structure presented above.
