    [0002] ELECTROLUMINESCENCE IN PHOTOVOLTAIC PLANTS AND THEIR SYSTEM OF
    [0004] OBJECT OF THE INVENTION
    [0005] The present invention refers to a guiding system for a mechanical equipment for carrying out electroluminescence measurements in photovoltaic plants that facilitates and speeds up the realization of electroluminescence averages for the solar panels that make up photovoltaic plants; thus managing to increase productivity. The invention thus allows the characterization of each of the solar cells present in the solar panels that make up the photovoltaic plants; where the objective of the invention is to be able to carry out processes to control the state of solar cells in a precise, efficient and fast way.
    [0007] TECHNICAL SECTOR
    [0008] The present invention can be encompassed in the renewable energy sector, specifically in the field of inspection and quality control of photovoltaic modules.
    [0010] BACKGROUND OF THE INVENTION
    [0011] To date, the electroluminescence characterization process of solar panels is carried out with a tripod, a suitable photographic camera, a power supply and a computer.
    [0013] This structure presents a series of limitations when it comes to being able to adequately characterize all the panels present in photovoltaic plants.
    [0015] When making images of the different panels in a plant, all the equipment must be moved to position it in front of each of the panels where the measurement is made. As it is a device with several components, it implies investing a certain amount of time in this transfer, at the same time that the sensor must be focused each time the camera is moved, since its position will not be the same as in the previous measurement . This poses a problem when characterizing the modules, since it limits the productivity (modules / hour) of the inspection.
    [0016] Due to the position of the tripod, the camera cannot be positioned in the center of the panel and so that the detector is parallel to the module. Because of this, two things happen: on the one hand, the images of the most distant solar cells have a lower resolution than the closest ones. On the other hand, solar cells present a certain deformation, from the furthest to the closest, which implies that, when determining the state of solar cells, it can be laborious to determine which faults they may present. To avoid this, a pole attached to a higher tripod should be used. However, this solution gives rise to vibrations that in many cases prevent the correct taking of the images.
    [0018] Another method of electroluminescence measurement that currently exists is based on a large structure, made up of a large number of bars, which makes it a difficult structure to handle and transfer to the place where the measurements are to be made.
    [0020] This type of structure is very complex and is made up of a large number of bars, which makes the structure have a greater weight, which can be harmful to the surface of the solar cells, since as this structure slides on the solar panels , if it is too heavy, it can even damage its condition. In turn, due to its large dimensions, it is difficult to handle and move to the measurement site, and it cannot be adapted to the different types of photovoltaic plants that exist on the market.
    [0022] On the other hand, since the panels of a solar plant are placed in independent structures called tables, it is necessary once the measurement of the panels of a table is finished, to lift the structure and position it on the next table.
    [0024] This situation is complicated due to the high weight of the structure and the fact that the spaces between the different tables are often limited, making maneuvering considerably more difficult. All of this carries significant risks of damaging the panels during installation as well as penalizing the frequency of the measurement.
    [0026] On the other hand, this system has a large surface area increasing the effective section exposed to the wind, which limits its use to atmospheric conditions in which the air velocity is very small.
    [0028] This structure does not make it possible to measure panels found on roofs or on floors where the position of the modules is difficult to access and makes it impossible to take electroluminescence measurements with the large structures mentioned above.
    [0030] Another of the most innovative processes that have emerged as a result of the increasingly widespread use of UAVs (unmanned aerial vehicles) is the use of drones, which are incorporated with cameras capable of capturing the surface state of the solar panels.
    [0032] One of their disadvantages is that they are very sensitive to effects such as the wind, causing that, in the face of a gust of air, it can be displaced, not making the measurement process possible due to that movement, and in turn, if it is pushed by the wind against the panels you are measuring, it can impact against them, damaging their surface.
    [0034] Another drawback of the UAV measurement system is that because it is a system that is flying, it is not stable, so the measurement process can give bad results, since the capture of the surface state of the solar cells must be done without vibrations or movements that could affect the results of the measurements and, in turn, the objective of the photographic camera would need to be focused every time it changed position or height with reference to the modules.
    [0036] DESCRIPTION OF THE INVENTION
    [0037] In order to achieve the objectives and avoid the drawbacks mentioned in the previous sections, the invention proposes mechanical equipment for carrying out electroluminescence measurements in photovoltaic plants and its guidance system.
    [0039] The mechanical equipment comprises a lower frame that includes at least one rectangular base frame, a gantry fixed at its ends to the rectangular base frame, a photographic camera coupled to the gantry, first wheels and second omni-directional wheels that are configured to facilitate movement. of the mechanical equipment on solar panels of photovoltaic plants that are arranged on an inclined plane.
    [0041] The rectangular frame comprises two first tubular profiles corresponding to the smaller sides of the rectangular base frame, and two first extensible structures corresponding to the larger sides of the rectangular frame.
    [0043] Instead, the gantry comprises two second vertical extensible structures and a third horizontal extensible structure that is joined by its end sections to two upper end sections of the second vertical extensible structures.
    [0045] The photographic camera is fixed on a height-adjustable shoe device, which is fixed to a skid that is coupled to a longitudinal guide of the third horizontal extensible structure of the gantry; where the camera is configured to focus downward in a direction perpendicular to a plane of the solar panels on which the first wheels rest.
    [0047] The third and the first extensible structures comprise pairs of tubular profiles aligned with each other; and anchoring devices that link the pairs of tubular profiles of the extensible structures.
    [0049] The first two tubular profiles and the first two extensible structures of the rectangular base frame are joined at their end sections by pairs of first brackets in combination with anchoring elements; where the first tubular profiles are located in an upper plane above a lower plane where the first two extensible structures meet.
    [0051] The second vertical extensible structures and the third horizontal extensible structure of the gantry are joined at their end sections by pairs of second brackets in combination with anchoring elements; where the second and third extensible structures of the gantry are located in different parallel planes.
    [0053] Some lower end sections of the second vertical extensible structures are joined to the first tubular profiles of the rectangular base frame by means of pairs of third brackets in combination with anchoring elements.
    [0054] The mechanical equipment of the invention also includes handles attached to at least one of the first two extensible structures of the rectangular base frame.
    [0056] The mechanical equipment also comprises a support box fixed to the support base frame; wherein said support box is configured to support a computer.
    [0058] The first wheels and the second wheels are coupled on first supports and on second supports that are fixed to the rectangular base frame; where the first supports are fixed to the first tubular profiles; and where the second supports are attached to the first extensible structures.
    [0060] In another embodiment of the invention, the lower frame comprises the rectangular base frame and an additional structure fixed to the rectangular base frame by means of additional brackets; where the first wheels are coupled to the rectangular base frame by means of the first supports, while the second wheels are coupled to the additional structure.
    [0062] Each one of the anchoring devices that links each pair of tubular profiles, comprises screws and stepped bars that include centered threaded holes; where said stepped bars fit into some pipes located along the entire length of the pairs of tubular profiles of the extensible structures; and where the anchoring devices are configured to fix the length of the extensible structures.
    [0064] The guiding system of the mechanical equipment comprises guiding means located along a longitudinal edge located in the highest part of the solar panels; where said longitudinal edge is configured to provide support by contact of the omni-directional wheels, while the first wheels are configured to support on a surface of the solar panels arranged in an inclined plane.
    [0066] The described invention remedies all the drawbacks in the measurement process, positioning the camera perpendicular to the modules of the solar panels and with the sensor parallel to them thanks to the structure on which it goes built-in camera. The equipment moves along the solar panels, making the entire measurement process easier and faster.
    [0068] As the camera is always in the same position and at the same distance from the solar panels, it is not necessary to focus the camera lens every time it moves along the solar panels, since said camera is always at the same distance from the solar panels. In this way the frequency of measurements is considerably increased. Once said camera lens is set for the first measurement process, it is used for the rest of the photovoltaic plant.
    [0070] The present invention allows, thanks to the type of profiles of which it is composed, that it be a versatile structure, being able to adapt to each type of photovoltaic plant, simply by regulating the position that each profile must have so that it adapts to the dimensions of the modules of solar panels and being able to place the set of wheels that most facilitates the measurement process, so that the number of first wheels and second wheels can vary.
    [0072] By having a totally modular configuration, one of the advantages of the equipment of the invention is that it can cover as many solar panels as necessary, since all that is needed is to join more profiles and achieve the dimensions of the equipment that is required. This allows the team to be able to adjust both in height, width and length, without it being necessary to focus the camera lens each time.
    [0074] The present invention aims to facilitate the processes of control of the state of the solar cells present in the photovoltaic solar panels of solar plants, significantly increasing the productivity (number of panels / hour controlled) of the measurements.
    [0076] The equipment of the invention comprises a structure made of profiles that can all be of the same type and of a material that allows it to be light, and all the equipment can be transported by a single person. Thanks to this type of profile used, it makes the mechanical equipment easy to assemble and disassemble in the place where the control process of the photovoltaic solar panels is desired.
    [0077] To solve the problem of the distance that must exist between the camera and the panels, the skid that supports said camera is located in the third extensible structure of the portico, so that the skid is configured to slide along along the third extendable structure. This skid incorporates the necessary base to be able to screw the camera
    [0079] As for the profiles that make up the structure of the mechanical equipment, they are numbered to be able to carry out the assembly following these numbers in a simple plan. This is how a fully modular and scalable system is configured.
    [0081] The joints between profiles are simple and mechanical, without requiring any type of welding, since they are designed in such a way that they provide the necessary rigidity to the overall structure of the equipment of the invention.
    [0083] Likewise, the invention has the first wheels and second wheels that are of different sizes and different characteristics that allow both wheels to position, hold and move the entire equipment of the invention on the solar panels. All wheels have suitable fasteners that allow them to rotate freely.
    [0085] The second wheels are omni-directional, so that they can roll in perpendicular directions, while at the same time being positioned below the first wheels.
    [0087] In this way they allow the solar panels to initially move upwards and once the highest part of the solar panels is reached, the structure of the mechanical equipment would fall down by gravity until the second wheels settled on the corresponding longitudinal edge of the row. top of solar panels. At this time, the second wheels will serve as a stop to support the mechanical equipment, while allowing a smooth sliding by means of rotation due to their peculiar shape.
    [0089] Being a versatile structure, the wheel set can be arranged in the most comfortable way for later work. Positioning them this way It allows moving the equipment along the solar panels and in turn fulfills the function of serving as a support by supporting the weight of the equipment.
    [0091] The mechanical equipment has handles that help when placing said equipment on the solar panels and facilitate its transfer along the rows of photovoltaic panels once it is positioned on them and measurements are being made.
    [0093] The equipment also includes the support box where the computer that controls the photographic camera is located and some batteries that power the entire set. The computer has a Wi-Fi system to be able to operate remotely with it, using a Tablet or a smartphone.
    [0094] Specifically, the advantages that the invention presents with respect to existing measurement systems and that therefore provide novelty to the system and the mechanical equipment of the invention when making measurements are the following:
    [0096] -The structure is modular, compact, light, easy to move, removable and adjustable to different sizes.
    [0098] -The position of the camera responsible for capturing the surface of the cells is perpendicular to the solar panels to minimize deformation in the capture of images, thus making better assessments of the state of the solar panels. In turn, the structure provides the camera with sufficient height to be able to capture a complete module in a single image.
    [0100] - The height of the gantry where the camera is attached can be adjusted so that the camera can be brought closer to the module, increasing the resolution of the images to detect small defects.
    [0102] - Allows to measure the largest number of panels that make up the tables, allowing access to those furthest from the operator.
    [0104] - Carry out the fewest possible movements of the different parts that make up the measurement system.
    [0105] - The structure of the mechanical equipment assembly facilitates the change from one table to another in the photovoltaic plant.
    [0107] - Facilitates the movement of the camera to take the images of the panels consecutively.
    [0109] - The measurement process is carried out in short periods of time.
    [0111] - The structure of the mechanical equipment is easy to move and rolls on the solar panels, so that in this way measurements are made in the shortest possible time.
    [0113] - The structure of the mechanical equipment is robust enough and with a very small cross-section to reduce vibrations due to external factors such as wind.
    [0115] The mechanical equipment of the invention is, as already mentioned above, totally modular, counting for this with removable structural elements that allow adaptation to the different dimensions that a photovoltaic plant can present. This also allows the mechanical equipment to be easily transportable and to take up little space.
    [0117] On the other hand, it is emphasized that the photographic camera can move relatively in the three directions of space and therefore can be located at any point in space.
    [0119] Below, to facilitate a better understanding of this specification and forming an integral part thereof, some figures are attached in which the object of the invention has been represented by way of illustration and not limitation.

    [0131] PREFERRED EMBODIMENT OF THE INVENTION
    [0132] Considering the numbering adopted in the figures, the mechanical equipment 1 for carrying out electroluminescence measurements in photovoltaic plants comprises a rectangular base frame 2, a portico 3 coupled at its ends to the rectangular base frame 2, a photographic camera 4 coupled on the portico 3, first wheels 5 and second omnidirectional wheels 6; where both wheels 5, 6 are coupled on the rectangular base frame 2, respectively, by means of first rotatable supports 5a and by means of second supports 6a.
    [0134] Said wheels 5, 6 are configured to facilitate the movement and guidance of the mechanical equipment 1 on solar panels 7 supported on at least one table 8.
    [0136] Each of the solar panels 7 includes a set of solar cells 7 'on which the processes to control the surface state of said solar cells will be carried out precisely, efficiently and quickly.
    [0138] The rectangular frame 2 comprises two first tubular profiles 9 corresponding with the smaller sides of the rectangular base frame 2, and two first extensible structures corresponding to the larger sides of the rectangular frame 2; wherein each of the first extensible structures 10 comprises two aligned tubular profiles 10a, 10b, and an anchoring device (span connector) shown in Figure 6. Said anchoring device links each pair of tubular profiles 10a, 10b to each other; so that the anchoring device allows the length of each of said first extensible structures 10 to be varied; all this to be able to vary the dimensions of said rectangular base frame 2 in parallel to its longer sides.
    [0140] The pair of first tubular profiles 9 and the pair of first extensible structures 10 of the rectangular base frame 2 are joined at their end sections by pairs of first brackets 11 in combination with anchoring elements such as screws; where the first tubular profiles 9 are located in an upper plane above a lower plane where the first two extensible structures are located 10. At least one of the first extensible structures 10 includes handles 12 to be able to comfortably manipulate the entire equipment mechanical while moving over the solar panels 7.
    [0142] On the rectangular base frame 2 is fixed a support box 13 that supports a computer 14 to be able to control the electroluminescence values.
    [0144] The gantry 3 comprises two second vertical extensible structures 15 and a third horizontal extensible structure 16 that is joined at its end sections to two upper end sections of the second vertical extensible structures 15 by means of second pairs of brackets 17 in combination with screws.
    [0146] The second and third extensible structures 15 and 16 of the gantry 3 are located in different parallel planes that are perpendicular to the parallel planes in which the first tubular profiles 9 and first extensible structures 10 of the rectangular base frame 2 are located.
    [0148] Some lower end sections of the second vertical extensible structures 15 of the gantry 3 are joined to the first tubular profiles 9 of the rectangular base frame 2 by means of third pairs of brackets 18 in combination with other anchoring elements.
    [0149] Each of the second vertical extensible structures 15 comprises telescopic coupling. In this way the third horizontal extensible structure 16 can be positioned at different heights.
    [0151] Instead, the third horizontal extensible structure 16 comprises two aligned tubular profiles 16a, 16b, and an anchoring device (as described above that is included in the rectangular base frame 2) that links the two tubular profiles 16a, 16b to each other; so that the anchoring device allows the length of said third horizontal extensible structure 16 to be varied; where during the variation of the dimension of the rectangular base frame 2 the length of the third horizontal extensible structure 16 of the gantry 3 is also varied in parallel.
    [0153] The photographic camera 4 is fixed on a conventional shoe device 25, which is in turn fixed on a skid 19 that is coupled on a longitudinal guide 20 of the third horizontal extensible structure 16 of the gantry 3, so that the assembly of skate 19 and chamber 4 can be moved along said longitudinal guide 20.
    [0155] The shoe device 25 allows the height of the photographic camera 4 to be adjusted to be able to adjust and fine-tune the focus of said photographic camera 4 with respect to the solar cells 7 'of the solar panels 7.
    [0157] The first wheels 5 are linked to the first two tubular profiles 9 of the rectangular base frame by means of the first supports 5a, while the second wheels 6 are linked to one of the two pairs of first extensible structures 10 of the rectangular base frame 2.
    [0159] In one embodiment of the invention, the profiles that make up the reinforcement of the mechanical equipment of the invention are aluminum profiles, with the possibility that they all have basically the same dimensions.
    [0161] Each of the anchoring devices that link the pairs of tubular profiles of the first and third extensible structures 10, 16, comprises stepped bars 26 that include centered threaded holes 26a; where said stepped bars 26 fit into pipes 27 located along the entire length the pairs of tubular profiles 10a, 10b, 16a, 16b of the extensible structures 10, 16, so that once the desired length of the respective extensible structure has been determined, the pair of tubular profiles is immobilized by means of the anchoring device, which includes in addition, for this purpose, screws 28 are threaded into the centered threaded holes 26a and abut, at their ends, on a bottom of the pipes 27.
    [0163] The union of the four sides of the rectangular base frame 2 is done by means of the first pairs of metal brackets 11, thus forming the base of the mechanical equipment that will roll over the photovoltaic solar panels 7, thanks to the first and second wheels 5, 6 located at the bottom below the rectangular base frame 2.
    [0165] The different profiles of the equipment of the invention are numbered by silkscreen printing to facilitate their assembly according to the ascending order of numbering.
    [0167] The different brackets 11, 17 and 18 help to stiffen the armor of the equipment of the invention, preventing vibrations and displacement in the face of adverse weather conditions.
    [0169] The invention has a versatile arrangement of its construction elements, thus being able to position the supports 5a, 6a of the wheels 5, 6 in the most comfortable way that allows a more efficient work when rolling the mechanical equipment 1 about solar panels 7.
    [0171] To carry out the movement of the equipment of the invention on the surface of the solar panels 7, it is enough to grasp the handles 12 (handles) arranged on the profiles that are part of the rectangular base frame 2. If it is considered necessary, for example, to In order to increase the length of the longer sides of the rectangular base frame 2, it is possible to add another pair of wheels that will make the assembly more rigid.
    [0173] By means of the photographic camera 4 installed in the shoe device 25 fixed to the skid 19, data collection works can be carried out by means of the electroluminescence technique. Said installation will be made by thread.
    [0174] As mentioned above, the height of the photographic camera 4 is adjustable thanks to the telescopic coupling of the two second vertical extensible structures 15, thus having the possibility of working at different distances from the solar panels 7 obtaining images that cover a smaller surface, but with a better resolution.
    [0176] Once the mechanical equipment of the present invention has been placed on the photovoltaic solar panels 7, the computer 14 must be placed in the corresponding box 13 for the corresponding data collection and processing. From there, the mechanical equipment 1 will move by rolling along each of the rows 21, 21 'of solar panels 7 of the photovoltaic plant with the help of the handles 12 arranged on one of the larger sides of the base frame. rectangular 2.
    [0178] The connecting cables between the photographic camera 13 and the computer 14 go through channels. To facilitate assembly and disassembly of the equipment of the invention, each cove has its own section of cable that is connected to that of the next by means of a male-female connector.
    [0180] On the rectangular base frame 2, the support box 13 for the computer 14 is fixed together with the power batteries, which allows the corresponding electroluminescence measurements to be carried out.
    [0182] Normally, the solar panels 7 are placed in inclined planes on the table 8, so that it can be seen how once the mechanical equipment 1 is located on the top of the solar panels 7 in correspondence with the upper row 21 of solar panels plus raised, the second omni-directional wheels 6 prevent the mechanical equipment 1 from sliding downward. It is also noted how the rolling of the second wheels 6 facilitates and allows the guided movement of the equipment between the different modules of separate solar panels 7 supported by adjacent tables 8.
    [0184] Figure 4 shows two rows 21, 21 'of solar panels 7, as well as the relative arrangement of the two types of wheels 5, 6 to illustrate how is the movement of movement from the bottom row 21' of modules of solar panels 7 located in a lower part to the upper row 21 of the upper part. This movement is made on the second omnidirectional wheels 6 and on the first wheels 5 placed in the lowest part of the mechanical equipment 1; so that the other pair of first wheels 5 are located in a non-contact raised position on the solar panels 7.
    [0186] Once the upper part of the solar panels 7 of the upper row 21 is reached, the second omnidirectional wheels 6 would be in the position seen in figure 2, resting on a longitudinal edge 22 of the upper row 21 of solar panels 7; where in this situation the set of mechanical equipment 1 can be moved along the upper row 21 of solar panels 7; and where the mechanical equipment will rest on the solar panels 7 through the first wheels 5 and will be guided through the second wheels 6 along the longitudinal edge 22 of the upper row 21 of solar panels 7.
    [0188] Figure 5 shows a plan view showing pairs of rows 21, 21 'of solar panels 7 supported on respective tables 8, so that between the solar panels 7 of one table and another 8 there is a transverse space 23 that separates 8 adjacent tables of solar panel groups 7.
    [0190] Both the rectangular base frame (2) and the gantry (3) can be provided with movement so that it can move autonomously.
    [0192] Different materials that increase the lightness of the assembly of the mechanical equipment 1 can be used to increase the rigidity.
    [0194] The movement of the mechanical equipment 1 could be motorized so that it moves without human intervention on the tables.
    [0196] The combination of the different profiles of the mechanical equipment 1 allows a modular and scalable configuration, allowing it to be adapted to any size of photovoltaic solar panel.
    [0198] It should be noted that the second wheels 6 are bidirectional allowing movements in perpendicular directions and also allow the attachment of the entire equipment mechanical 1 on one of the rows 21,21 'of the solar panels 7, without penalizing their displacement.
    [0200] On the other hand, figure 1b shows the mechanical equipment 1 of the invention that includes an additional structure 29 fixed to the rectangular base frame 2 by means of additional brackets 24. In this embodiment of the invention, the assembly of the second wheels 6 and second supports 6a are coupled to the additional structure 29 in order to be able to control the electroluminescence measurements in the lower row 21 'of solar panels 7, and even in other rows different from the upper row 21 when more than two rows are included in the photovoltaic plant; all this supporting the second wheels 6 on the longitudinal edge 22 of the solar panels 7 of the upper row 21.
