Description

Title of the invention: Installation method, in particular for solar panels, and installation device for implementing said method Technical field

[0001] The present invention relates to a method of installing solar panels on a receiving surface, and a method of installing solar panels on a receiving surface. Prior art

[0002] The installation of solar panels requires the intervention of qualified professionals to equip a receiving surface with a supporting structure in order to fix said panels there in compliance with the regulations in force, and in a position and orientation according to the sunshine. The term "solar panels" means both photovoltaic panels capable of providing electrical energy and thermal panels capable of providing thermal energy from solar energy. The term "receiving surface" means any flat surface on a roof of a building, a frame or on the ground to create solar fields, or the like, the receiving surface being able to be smooth, corrugated or structured, horizontal or inclined relative to the horizontal, provided on a fixed or adjustable frame capable of following the sun.Solar panels are typically positioned side by side in parallel rows, and in either a portrait or landscape layout. Rows of solar panels are also placed side by side or spaced as close together as possible to maximize the number of solar panels per unit area.

[0003] Supporting structures generally form grid structures. They are traditionally made from aluminum profiles forming rails, crosspieces, feet, etc. assembled by screwed fasteners, or similar. Aluminum is an expensive and heavy material which overloads the receiving surfaces. The assembly of the profiles requires specific tools. And, the assembly of these supporting structures is tedious, complex and time-consuming, because it requires first carrying out precise measurements, followed by equally precise tracing to precisely position and fix the rails and crosspieces, according to the dimensions of the solar panels to be installed. This work can only be carried out by qualified professionals.

[0004] Manufacturers have therefore sought solutions to simplify the installation of solar panels. They have developed modular supporting structures which are assembled in a "Meccano" manner and are partly assembled using quick-release fasteners. Examples are described in publications WO 2015 / 100474 A1 and US 10171027 B2. These load-bearing structures made of metal and / or thermoplastic are, however, expensive to manufacture, require ballast, use connecting pieces forming spacers, which consume raw material unnecessarily, and do not completely eliminate the need for prior measurements and marking out. In addition, some parts can be bulky and heavy to handle. Statement of the invention

[0005] The present invention aims to overcome these drawbacks by proposing a simplified installation method thanks to an installation device that is easy to handle by a single person, simple to implement without requiring specific qualification, said installation device being arranged to constitute an installation template allowing precise positioning of the solar panels without prior measurement or tracing, said installation device being at least partly eco-designed using recycled, lightweight, economical materials.

[0006] For this purpose, the invention relates to a laying method in which, consisting at least in the following steps: - using a laying device wound on itself around a winding axis to form a roll, said laying device being arranged to constitute a laying template, and comprising at least one longitudinal holding strip corresponding in whole or in part to a row of solar panels to be installed, and transverse support bars fixed at regular intervals on said holding strip, said interval corresponding to the mounting pitch of said solar panels to be installed, - fixing a first end of said retaining strip on said receiving surface, - unrolling said laying device, in which step said holding strip is arranged to unroll perpendicular to said winding axis, and positioning said support bars parallel to each other while respecting said assembly pitch, - fixing said retaining strip and / or said support bars on said receiving surface as said laying device is unrolled, and - fix said solar panels on said support bars.

[0007] The installation method further comprises unrolling said installation device over a length corresponding to the length of a row of solar panels to be installed. If its length is greater than the length of the row of solar panels to be installed, then the installation method comprises cutting said installation device. Conversely, if the length of the previous installation device is less than the length of said row, then the installation method comprises adding another installation device to continue said row of solar panels to be installed.

[0008] The installation method also consists of equipping the support bars of said installation device with fixing lugs projecting from said holding strip for fixing said solar panels, said fixing lugs being able to be of identical length or not, and attached or integrated into said support bars.

[0009] For this purpose also, the invention relates to a laying device, characterized in that it constitutes a laying template and comprises at least one longitudinal holding strip corresponding in whole or in part to a row of solar panels to be installed, and transverse support bars fixed at regular intervals on said holding strip, said interval corresponding to the mounting pitch of said solar panels to be installed, and in that said holding strip is flexible and arranged to be rollable on itself, so that said laying device can adopt at least one storage position in which it is rolled on itself around a winding axis to form a roll, and a use position in which it is at least partly deployed on said receiving surface.

[0010] Said holding strip may consist of a strip of material of width substantially equal to the length of said support bars or of at least two strips of material of equal length, said strips of material being arranged parallel to each other to form at least the two edges of said holding strip, so that the width of said holding strip is substantially equal to the length of said support bars.

[0011] Preferably, said retaining strip is made of a dimensionally stable material, at least in the direction of its length, in order to be able to perform its function as a laying template. It can be made from a solid, mesh or openwork canvas, and / or from a membrane stabilized or not by a reinforcing sheet, and in that it is obtained by a weaving, non-woven, extrusion and / or coating process, from textile, synthetic and / or composite materials.

[0012] Said retaining strip may further comprise an adhesive material based on tar, bitumen, mortar, glue, resin, or a composite based on natural and / or synthetic raw materials.

[0013] According to the embodiments, said retaining strip may comprise squaring members arranged in a cross between said strips of material and said support bars. In this case, said squaring members are also made of a dimensionally stable material, at least in the direction of their length, in order to be able to ensure their squaring function. They may be chosen from the group comprising ropes, cables, straps, obtained from textile, synthetic, composite and / or metallic materials.

[0014] Advantageously, the installation device comprises fixing lugs for fix said solar panels, said fixing brackets being able to be attached or integrated into said support bars, of identical length or not.

[0015] If said fixing lugs are integrated into said support bars, then they can be articulated on said support bars to adopt at least one passive position in which they are folded down and retracted into said support bars, and one active position in which they are deployed and protrude from said support bars to receive said solar panels.

[0016] Said support bars can be made from extruded, injected or pressed profiles, comprising a reinforced internal structure, in a material chosen from the group comprising a thermoplastic material reinforced or not by mineral and / or vegetable fillers, a composite material comprising or not fillers from recycled waste.

[0017] In addition, said installation device may advantageously comprise at least one electrical conductor added and / or integrated into said holding strip, said support bars and / or said squaring members to facilitate the earthing of the solar panels. Brief description of the drawings

[0025] [Fig.7] is a perspective view of a mounting module of the installation device [Fig.l], equipped with added fixing lugs. Description of the embodiments

[0026] In the illustrated embodiments, identical elements or parts bear the same reference numbers. Furthermore, terms that have a relative meaning, such as vertical, horizontal, right, left, front, back, above, below, etc., must be interpreted under normal conditions of use of the invention, and as shown in the figures. The X, Y and Z axes are defined by an orthonormal reference frame illustrated in [Fig.l]. Furthermore, the geometric positions indicated in the description and the claims, such as “perpendicular”, “parallel”, “symmetrical” are not limited to the strict sense defined in geometry, but extend to geometric positions that are close, that is to say which accept a certain tolerance in the technical field considered, without influence on the result obtained. This tolerance is notably introduced by the adverb “substantially”, without this term necessarily being repeated before each adjective.

[0027] With reference to the figures, and more particularly to [Fig.4], the installation device 1 according to the invention comprises a longitudinal holding strip 2 along the X axis and transverse support bars 3 along the Y axis, fixed perpendicularly and at regular intervals on the holding strip 2. The installation device 1 is designed as a rope ladder, in which the holding strip 2 defines a rectilinear row along the X axis for the installation of the solar panels 4 side by side, and the support bars 3 define the mounting pitch P of the solar panels 4 in said rectilinear row. The mounting pitch P corresponds at least to the width or the length of a solar panel 4 depending on its mounting position (portrait or landscape). Thus, the installation device 1 constitutes an installation template, which is sufficient in itself and makes it possible to dispense with the measurements and tracing prior to its installation.Therefore, the holding strip 2 has a total length substantially equal to a multiple of the width or length of the solar panels 4, and a width substantially equal to the length or width of the solar panels 4, depending on whether they are mounted in portrait or landscape orientation. Similarly, the support bars 3 have a length substantially equal to the length or width of the solar panels 4, depending on whether they are mounted in portrait or landscape orientation.

[0028] The holding strip 2 is advantageously made of a flexible material which can be wound on itself. Thus, the laying device 1 can adopt a storage position in which it is wound on itself around a winding axis E, parallel to the support bars 3 and therefore to the axis Y, to form a roll 5 ([Fig.l]), and a use position in which it is deployed in the axis X in whole or in part on a receiving surface S (figures 2 to 4).

[0029] [Fig.l] illustrates the installation device 1 in the storage position, rolled up on itself to form a roll 5 which can be transported and handled by a single person. The length of the holding strip 2 is chosen according to the number of solar panels 4 to be fixed in a row, but also taking into account the total weight of the laying device 1, which must remain within the acceptable load-bearing limit of an employee defined by the regulations in force. In this storage position, the laying device 1 is compact and has a reduced footprint. It can be easily stored, packaged, transported, brought to the site. If the site is at height, it can be transported by a simple lifting device in the same way as the rolls of bitumen used to waterproof roofs. It can be wrapped in a protective cover, filmed or simply strapped to prevent accidental unrolling. The presence of the support bars 3 gives the roll 5 a substantially square section, without this shape being limiting.The support bars 3 are further fixed to the retaining strip 2 by any suitable fixing means, such as screws, staples, rivets, adhesive and / or welding, depending on the materials from which the retaining strip 2 and the support bars 3 are made. The preparation of the installation device 1 is of course carried out in the factory to reduce the intervention time on the site.

[0030] The holding strip 2 is made of a dimensionally stable material, at least in the direction of its length along the X axis, and this whatever the climatic conditions. It must be non-extensible, that is to say have a zero or almost zero elongation, for example at most equal to 1 mm per linear meter, without this value being limiting, and insensitive to variations in temperature, to be able to perform its function as a laying template. It must in fact guarantee a deployment of the laying device 1 parallel to its winding axis E, so that it can extend longitudinally and perpendicular to its winding axis E, and form a rectilinearly deployed laying device 1. It must also guarantee a precise, regular and parallel positioning of the support bars 3, all along the laying device 1, to form several consecutive, rectangular and calibrated mounting modules 6.The parallelism of the retaining strip 2 and the interval between the support bars 3 must ensure that the solar panels 4 are installed within the permissible assembly tolerances.

[0031] The retaining strip 2 may consist of a strip of material (not shown) of width substantially equal to the length of the support bars 3. The strip of material may be made from a solid, meshed, openwork canvas, a membrane stabilized or not by a reinforcing sheet, or similar, obtained by a weaving, non-woven, extrusion, coating or similar process, from textile, synthetic or composite materials.

[0032] The holding strip 2 may also be made up of parallel strips of material 7, the width of the strips of material 7 being identical or not, and the number of strips of material 7 being greater than or equal to two. In the examples shown, the holding strip 2 is made up of two strips of material 7, of the same width, arranged to form the edges of the retaining strip 2, which has a total width substantially equal to the length of the support bars 3. The strips of material 7 can be made from a strap, a strip of material cut lengthwise and as defined above, or similar, obtained by a weaving, non-woven, extrusion, coating or similar process, from textile, synthetic or composite materials.

[0033] In this embodiment, the central part of the retaining strip 2 located between the two strips of material 7 can remain empty or include squaring members 8 (figures 3 and 5). In this case, the squaring members 8 are arranged in a cross between the two strips of material 7 and the support bars 3. They are also made of a dimensionally stable material, at least in the direction of their length, and this whatever the climatic conditions. They must be non-extensible, that is to say have a zero or almost zero elongation, for example at most equal to 1 mm per linear meter, without this value being limiting, be insensitive to temperature variations, to be able to ensure a squaring or parallelism function. They can be chosen from the group comprising at least ropes, cables, straps or the like, made from textile, synthetic, composite or metallic materials.

[0034] The holding strip 2 is designed to be fixed to a receiving surface S, preferably flat, smooth, corrugated or structured. For this purpose, a fixing system (not shown) is provided which can be integrated and / or attached to the laying device 1 depending on the nature and type of the receiving surface S. The fixing system can comprise screws, staples, rivets, and / or an adhesive. The fixing system can be provided punctually along the length of the holding strip 2, for example at the intersections between the holding strip 2 and the support bars 3, or continuously along the entire length of the holding strip 2 and / or along the entire length of the support bars 3. In the case of fixing members, such as screws, staples, rivets or the like, corresponding holes can be provided in the holding strip 2 and / or the support bars 3.In the case of an adhesive, this may consist of any bonding substance, such as a tarred product, a bituminous product, a mortar, a glue, a resin, a composite based on natural and / or synthetic raw materials, or the like, making it possible to intimately bond the installation device 1 to the receiving surface S. The receiving surface S may itself include a seal made by tarred or bituminous membranes. The adhesive may be added at least to the lower face of the retaining strip 2 and / or the support bars 3, by coating, impregnation or the like, or be an integral part of the retaining strip 2 and / or the support bars 3 by manufacturing. The different fixing systems may be combined depending on the nature of the surface. reception S.

[0035] The installation device 1 further comprises fixing lugs 9, 10 for solar panels 4 integrated or attached to the support bars 3. The fixing lugs 9, 10 can be equipped at their free end with notches 11, fixing clips 12 or the like, to receive the corresponding edge or angle of the solar panel frames 4 by simple fitting, self-locking fitting or the like.

[0036] The fixing clips 12 shown schematically by a stud in [Fig.7], may be fixing clips known for this type of application, and are not described in detail in the present application, because they do not form part as such of the invention. The notches 11, the fixing clips 12 or the like allow the mounting of the solar panels 4 by a quick fixing system thus avoiding the use of tools, without this example being limiting. In addition, each fixing lug 9, 10 may be provided to accommodate the corresponding angles of two adjacent solar panels 4. In all cases, each solar panel 4 is blocked in the three axes X, Y and Z between four fixing lugs 9, 10.

[0037] Depending on the geographical position of the receiving surface S and the possible inclination to be given to the solar panels 4 relative to the horizontal to maximize the capture of solar energy, the two fixing lugs 9, 10 provided on each support bar 3 may have an identical length or not. The orientation and inclination of the solar panels 4 are variable depending on the hemispheres, latitudes and longitudes of the installation location. In the Northern hemisphere, an orientation of the solar panels 4 to the South will be preferred, and at the latitude of France, for this South orientation, an inclination of between 30° and 35° will be preferred, as an example only.

[0038] With reference to [Fig. 5], the angle of inclination A of the solar panels 4 relative to the horizontal can be between 10° and 30°, without these values ​​being limiting. Depending on whether the receiving surface S is horizontal or inclined but not sufficiently, the prescribed angle of inclination A is then obtained by fixing lugs 9, 10 of different lengths ([Fig. 5]).

[0039] [Fig. 6] illustrates an example of a laying device 1 equipped with support bars 3 incorporating two fixing lugs 9 of different lengths. The length of the rear fixing lug 9 (on the left of the figure) is determined as a function of the angle of inclination A to be given to the solar panel 4. In this embodiment, the fixing lugs 9 are mounted on the support bars 3 by means of a joint 13 to be able to adopt a passive position (on the right of [Fig. 6]) in which they are folded down and housed in a recess 14 provided in said support bars 3, and an active position ([Fig. 5] and on the left of [Fig. 6]) in which they are deployed and protrude from said support bars 3 to receive the solar panels 4. The joint 13 may include a non-return member (not shown) for locking the fixing lugs 9 in the active position. In addition, the support bars 3 are hollowed out or perforated and include two recesses 14 of a length adapted to the length of the fixing lugs 9, in which the fixing lugs 9 retract without creating excess thickness in the passive position. Thus, the fixing lugs 9 do not hinder the rolling up of the installation device 1 on itself in the storage position.

[0040] [Fig. 7] illustrates another example of a laying device 1 equipped with support bars 3' on which fixing lugs 10 of different lengths are attached. In this example, the fixing lugs 10 are secured to the fixing bars 3' by any suitable fixing means, whether permanent or not, such as by clipping, gluing, screwing, magnetic fixing, or the like.

[0041] The support bars 3, 3', as well as the fixing lugs 9, 10, can be made of any suitable material offering good properties of mechanical strength, dimensional stability, resistance to climatic conditions (UV, temperature, humidity), for a relatively low density, for example less than 1. Profiles obtained by extrusion, injection, pressing or the like will preferably be chosen, which may include an internal structure reinforced by ribs, honeycombs or the like. Depending on the manufacturing method chosen, the profiles can then be cut to the required length and machined to integrate the recesses 14 and the hinge 13.We will preferably choose a thermoplastic material reinforced with mineral and / or vegetable fillers, or advantageously a composite material of the WPC (Wood Plastic Composite) type allowing the recycling and recovery of cardboard-based waste such as food packaging, beverage cartons, or similar, without these examples being limiting.

[0042] The advantage of this choice of material from recycled waste makes it possible to meet the specifications, to offer a product that is much lighter than aluminum, less expensive than aluminum or any other thermoplastic solutions, and to enter into a circular economy. In this example of composite material, the support bars 3, 3' and / or the fixing lugs 9, 10 may, if necessary, include metal inserts making it possible to provide a fixing and / or locking function, for example in the form of notches 11, fixing clips 12 or the like, at the ends of the fixing lugs 9, 10 to fix the frames of the solar panels 4. Thus, it is possible to combine different materials adapted to the functions to be fulfilled, making it possible to reduce the total weight of the installation device 1, to save on noble raw materials, to reduce the total cost of the installation device 1 and to propose an eco-responsible solution.

[0043] The installation device 1 according to the invention can be manufactured in a standardized version corresponding to a type of solar panels 4 and a type of installation, but also on demand and on a case-by-case basis depending on the dimensions of the solar panels 4, the installation orientation: portrait or landscape, the type of receiving surface S, and the angle of inclination A to be given to the panels. Thus, there is not a single model of installation device 1 but a plurality of models of installation devices 1 adapted to each need. The custom or on-demand manufacture of the installation device 1 according to the invention is easy to implement, within reasonable delivery times, and at lower cost, given the simplicity of design of the device and the modularity of the parts that constitute it.

[0044] With particular reference to Figures 1 to 5, the laying method according to the invention consists of at least the following steps, a) choose or manufacture one or more installation devices 1 as described above, depending in particular on the dimensions of the solar panels 4 to be installed, the portrait or landscape orientation of the solar panels 4, the number of panels to be installed, the nature of the receiving surface S, the presence or absence of an angle of inclination A of the panels; b) bring to the site the installation devices 1 selected and delivered in storage position ([Fig.l]) allowing simplified handling both on the ground and at height on a roof; c) position the first installation device 1 at one of the ends of the receiving surface S, at the top left for example of a rectangle, orienting it perpendicular to the first row of solar panels to be installed; d) fixing the end of the first laying device 1 on the receiving surface S, for example by gluing the first end of the retaining strip 2 provided with the first support bar 3; e) unrolling the first installation device 1 so that the retaining strip 2 unrolls perpendicular to its winding axis E and the support bars 3 are positioned parallel to each other while respecting the mounting pitch P of the solar panels 4 to be installed; f) fixing the first laying device 1 on the receiving surface S as it is unrolled, for example by gluing the retaining strip 2 over its entire length or over parts of its length and / or the support bars 3; g) unroll the number of mounting modules 6 which corresponds to the number of solar panels 4 to be installed on a first row; h) if necessary, cut the first installation device 1 to the desired length of the first row or, conversely, add a second installation device 1 to add the number of mounting modules 6 missing to complete the first row; i) if the number of solar panels 4 to be installed requires additional rows, parallel to the first row, then repeat operations c) to h) by positioning a second installation device 1 at the end of the receiving surface S, at the top left of the rectangle and below the first installation device 1, orienting it perpendicular to the second row of solar panels 4 to be installed and so on until the entire receiving surface S is covered.

[0045] By the verb "to fix", we mean to intimately link two pieces together, but also to immobilize one piece in relation to another piece, by any appropriate means such as ballast.

[0046] The installation device 1 according to the invention constitutes an installation template which advantageously replaces the measurements and tracing essential for the assembly of the supporting structures of the prior art. Indeed, the design of the installation device 1 ensures the parallelism of the holding strip 2 and the regularity of the mounting pitch P of the solar panels 4. As a result, the installation of a supporting structure obtained by this installation device 1 for the installation of solar panels 4 is rapid, and its implementation simplified, accessible to building professionals, not necessarily specialized in the field of solar panels.

[0047] The installation method also consists of installing the solar panels 4 on the supporting structure obtained by one or more installation devices 1 forming a grid on the receiving surface S. This step can be carried out as the installation devices 1 are put in place, or at the end when all the installation devices 1 are put in place, depending on the accessibility between the rows. To install the solar panels 4, the installation method also consists of adding fixing lugs 10 to the support bars 3' if the installation devices 1 are not provided with them ([Fig.7]), or pivoting the fixing lugs 9 provided on the support bars 3 if the installation devices 1 are provided with them ([Fig.6]) to bring them from a passive position to an active position. It is then sufficient to mount each solar panel 4 between four fixing lugs 9, 10, distributed in the four corners of the panel.Each fixing lug 9, 10 can be arranged to accommodate the corner or edge of two adjacent solar panels 4.

[0048] In the event that the receiving surface S is the ground or any other horizontal surface on which it is difficult or even impossible to fix the installation device 1 by screwing, stapling, riveting or gluing, then it is possible to ballast the installation device 1 by any appropriate means such as sandbags or the like, placed on the retaining strip 2 and / or the support bars 3 before the solar panels 4 are put in place.

[0049] The laying device 1 may also comprise one or more electrical conductors added and / or integrated into the retaining strip 2, the bars of support 3 and / or the squaring members 8 to facilitate the connection to the earth or to a reference potential of the solar panels 4, when it comes to photovoltaic panels in particular.

[0050] The present invention is of course not limited to the embodiments described but extends to any modification and variant obvious to a person skilled in the art within the limits of the appended claims. Furthermore, the technical characteristics of the different embodiments and variants mentioned above may be, in whole or in some cases, combined with each other.
