Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic modules, and particularly to a high light transmittance photovoltaic module. Background Art

[0002] A high light transmittance photovoltaic module is a photovoltaic module manufactured using advanced materials and processes, with excellent light transmission performance and high power generation efficiency. High light transmittance means that more sunlight can penetrate the surface of the module and be absorbed and utilized by the solar panels, thereby improving the light energy utilization efficiency.

[0003] In the Chinese patent with the patent publication number CN115763600A, a high light transmittance photovoltaic module is disclosed, which includes a back plate having a docking surface and a mounting surface, a first notch provided on the docking surface, positioning grooves arranged side by side at the bottom of the first notch, a first adhesive film layer provided with side-by-side strip-shaped through holes and even rows of positioning notches, with the positioning notches in adjacent rows being offset, a photovoltaic power generation layer including solar cells adapted to the positioning notches and connected in series in sequence, a second adhesive film layer provided on the first adhesive film layer, and a cover plate hermetically bonded to the docking surface. The high light transmittance photovoltaic module facilitates the positioning of the first adhesive film layer by providing the first notch on the back plate, and then facilitates the positioning of the solar cells through the positioning notches. The adjacent solar cells are connected in series by conductive strips in the positioning space, which is convenient for assembly and avoids the offset of the solar cells. At the same time, the overall thickness of the module is reduced, the light transmittance is increased, and the staggered distribution of the solar cells is ensured by the offset positioning notches, thereby ensuring the light transmission amount.

[0004] However, the device in the above-cited document still has the following defects during specific use: 1. Compared with the device in the above-cited document, the solar cells are staggered by the offset positioning notches, which means that the connection stability between the positions with solar cells and without solar cells and their support structures is inconsistent. In actual applications, especially when facing external forces such as strong winds and snow, the overall mechanical stability of the photovoltaic module will be affected. Moreover, the staggered distribution of the solar cells makes the internal spacer layer areas of the module inconsistent, with a small spacing at the positions where the solar cells are installed and a large spacing at the positions where no solar cells are installed, making it difficult to ensure good sealing.

[0005] 2. Meanwhile, although the staggered distribution reduces the direct light blocking by the solar cells to a certain extent, due to the height difference between the solar cells and the adjacent vacant positions, new shadow areas will be generated at different lighting angles. These shadows prevent some solar cells from fully receiving light, not only affecting the light transmittance, but also causing current imbalance between the solar cells, reducing the power generation performance of the photovoltaic module. Moreover, the staggered distribution of the solar cells makes the light propagation path inside the module complex, with different light scattering and reflection conditions at different positions, resulting in uneven spatial distribution of the light passing through the photovoltaic module, showing an alternating pattern of light and dark, which affects the daylighting effect and visual comfort inside the building.

[0006] 3. Compared with the prior art, when installing the overall device, bolts and other stabilizing components are generally used. When using bolts and other fasteners for installation, it is necessary to accurately place and adjust the position of the photovoltaic module, and then pass the bolts through the pressing block and the bracket for fixation. This process is relatively complex and requires certain professional skills and experience to ensure the correct installation process and avoid unnecessary damage to the module. In addition, during the installation process, if the operation is improper, such as hitting the module or stepping on the module, it will also cause hidden cracks inside the module, thus affecting its power generation performance and service life.

[0007] Therefore, in view of this, the present invention proposes a high light transmittance photovoltaic module to make up for and improve the deficiencies of the prior art. Summary of the Invention

[0008] To solve the above technical problems, the present invention provides a high light transmittance photovoltaic module to solve the technical problems proposed in the above background art.

[0009] To achieve the above objectives, the technical solution adopted by the present invention is: a high light transmittance photovoltaic module, including a metal frame, a glass sheet is installed inside the metal frame, and a light effect optimization mechanism is arranged inside the metal frame. The light effect optimization mechanism is used to reduce the covering layer inside the metal frame and thus improve the overall light transmittance.

[0010] Further, the light effect optimization mechanism includes a photovoltaic panel installed inside the metal frame. Elastic plate clips are evenly installed below the photovoltaic panel, solar cells are installed inside the elastic plate clips, and a backplane is installed below the solar cells.

[0011] Further, the photovoltaic panel is in a grid shape as a whole, and installation grooves are opened at positions corresponding to the solar cells below the photovoltaic panel. The photovoltaic panel and the elastic plate clips are movably connected through the installation grooves.

[0012] By adopting the above technical solution, the solar cells can be installed and disassembled individually without affecting the structure of the entire photovoltaic module, thus greatly shortening the maintenance time.

[0013] Furthermore, cables are arranged inside the solid frame parts of the spring plate clips, and the battery cells are all installed at the positions of the lower frame entities of the photovoltaic panels. The photovoltaic panels and the battery cells are connected by flexible circuits, so as to make full use of space and increase the light penetration path while ensuring the power generation area.

[0014] By adopting the above technical solution, the part of the traditional backplane located below the battery cells is removed, so that more light can penetrate the component and directly irradiate the room.

[0015] Furthermore, the photovoltaic panels and the battery cells are vertically installed, and inclined panels are installed between every two adjacent battery cells. The inclined panels are fixedly connected to the photovoltaic panels, and the tip positions of the inclined panels face downwards.

[0016] By adopting the above technical solution, the interval area between them can be increased through the vertical installation method, so that the heat dissipation channel between the battery cells and the light plate can be smoother.

[0017] Furthermore, limiting interlayers are symmetrically and fixedly connected to the side walls of the metal frame. Buffer pads are uniformly installed inside the limiting interlayers corresponding to the side walls of the photovoltaic panels. The buffer pads are in a corrugated shape as a whole, and both ends of the buffer pads are fixedly connected to the metal frame and the side walls of the photovoltaic panels respectively.

[0018] By adopting the above technical solution, the buffer pads are arranged in a corrugated shape as a whole, which can increase the contact area between them and the metal frame and the side walls of the photovoltaic panels, thereby improving the firmness of the connection.

[0019] Furthermore, arc-shaped protrusions are uniformly installed above the backplane, and the arc-shaped protrusions are all located between adjacent battery cells.

[0020] By adopting the above technical solution, the light is reflected to the battery cells, thereby making up for the light quantity received by the vertically installed battery cells and realizing the light energy conversion efficiency.

[0021] Furthermore, a quick assembly mechanism is arranged outside the metal frame. The quick assembly mechanism is used to quickly adjust the installation positions between different metal frames and quickly install different metal frames. The quick assembly mechanism includes a lower splicing block and an upper splicing block installed on the side wall of the metal frame. A through groove is opened inside the upper splicing block, and a sliding shaft is slidably connected inside the through groove. A magnetic sheet cap is installed at the end of the sliding shaft.

[0022] Furthermore, protrusions and grooves are alternately arranged on the sides of the lower splicing block and the upper splicing block close to each other. Guide grooves are opened on the side walls of the protrusions in the lower splicing block, and guide posts are installed on the side walls of the protrusions in the upper splicing block.

[0023] By adopting the above technical solution, it plays an accurate guiding role during the splicing process, ensuring that adjacent frames can be accurately aligned and spliced.

[0024] Furthermore, the bump parts in the lower splicing block and the upper splicing block are both provided in a hollowed-out shape, and support frames are installed inside the bumps in the lower splicing block and the upper splicing block.

[0025] By adopting the above technical solution, the angular support frame provides the necessary stability for the structure. As one of the most stable geometric shapes, the triangle can effectively resist external pressure and deformation.

[0026] Furthermore, the inner diameter size of the magnetic sheet cap is equal to that of the through groove. The sliding shaft is threadedly connected to the magnetic sheet cap, and the magnetic sheet cap is entirely made of magnet material.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The present device designs the photovoltaic panel into a grid shape, and evenly installs the battery cells at the solid frame part on the back of the grid shape. Then, by reducing the battery blocking surface, that is, removing the part of the traditional backplane located below the battery cells, more light can penetrate the component and directly irradiate into the room. The grid shape design reduces the hindrance that light encounters during the penetration process, thereby improving the overall light transmittance. The characteristic of high light transmittance enables this kind of photovoltaic component to better integrate with the building appearance, meeting both the lighting requirements of the building and realizing the function of photovoltaic power generation. It is applicable to buildings with high requirements for lighting and aesthetics, such as glass curtain wall buildings, sunrooms, etc., and has high practical value.

[0028] Secondly, the introduction of the arc-shaped transparent reflector can reflect light to the battery cells without affecting the light transmittance, thereby making up for the light amount received by the vertically installed battery cells and realizing the light energy conversion efficiency. Moreover, the transparent reflector can not only reflect light to the battery cells, but also, through its special reflection characteristics, redirect the originally scattered or lost light to the battery cells, thereby improving the utilization rate of light. Through the above design, the component can maintain a high light energy conversion efficiency at different lighting angles.

[0029] Among them, the fixed connection between the limiting interlayer and the buffer pad can ensure the stable position of the photovoltaic panel within the metal frame, preventing it from shifting or shaking during installation or use, thereby improving the structural stability of the entire photovoltaic component. Secondly, the overall wavy shape design of the buffer pad can increase its contact area with the metal frame and the side wall of the photovoltaic panel, thereby improving the firmness of the connection. At the same time, the wavy buffer pad also has good elasticity and buffering performance, and can absorb and disperse external impact forces to a certain extent, protecting the photovoltaic panel from damage, and thus effectively improving the impact resistance of the photovoltaic panel.

[0030] Embodiment of practical effect: Among them, since the structures of the photovoltaic panel and the solar cell only have appearance differences from the prior art, and the structures in this device have consistent regularity and modularity, therefore, it is easy to be manufactured standardly during the production process, reducing costs. Moreover, the grid-shaped photovoltaic panel has good mechanical stability and is suitable for installation on various building surfaces. Whether it is a flat wall or a special-shaped building structure such as a dome with a certain curvature, it can be installed in a fitting manner by flexibly combining units, greatly expanding the application scope of photovoltaic modules in the building field.

[0031] Among them, the uniform and perpendicular installation method between the solar cell and the photovoltaic panel helps to achieve uniform stress distribution. In a photovoltaic module, the connection between the solar cell and the photovoltaic panel often bears relatively large stress. Through uniform and perpendicular installation, it thus avoids the damage of the solar cell or the deformation of the photovoltaic panel caused by stress concentration. This uniform stress distribution improves the mechanical stability and durability of the photovoltaic module.

[0032] Among them, the uniform and perpendicular installation method is also beneficial to improving the heat dissipation performance of the photovoltaic module. During the operation of the photovoltaic panel, the solar cell will generate a certain amount of heat. By increasing the interval area between the two through the perpendicular installation method, the heat dissipation channel between the solar cell and the photovoltaic panel can be made more unobstructed, which is conducive to the timely dissipation of heat, thereby reducing the working temperature of the solar cell and improving the power generation efficiency and stability of the photovoltaic module.

[0033] Among them, through the modular design of the installation groove between the solar cell and the photovoltaic panel, the solar cell can be installed and disassembled separately without affecting the structure of the entire photovoltaic module, thus greatly shortening the maintenance time and improving the maintenance efficiency. In addition, the modular design also makes the upgrade and expansion of the photovoltaic module more flexible. With the progress of technology, if it is necessary to replace a higher-efficiency solar cell, there is no need to carry out large-scale transformation of the entire system.

[0034] (2) This device uses a splicable tooth-shaped frame design, enabling the lower splicing block and the upper splicing block to be interlocked through bumps and grooves. During installation, only by bringing adjacent frames closer and aligning them can the preliminary splicing and positioning be quickly completed, greatly simplifying the installation steps. Secondly, after the preliminary splicing is completed, by exhausting the air between the frames, a closer fit is formed between the frames. After the air is exhausted, the external atmospheric pressure will further press the frames tightly, enhancing the connection stability between the frames by using atmospheric pressure and reducing the risk of component shaking or displacement caused by frame loosening, thus improving the stability of the installation structure of the entire photovoltaic module.

[0035] Compared with the prior art, this device does not require fine position adjustment and tightening operations like using bolts, reducing the installation difficulty. Even inexperienced installers can complete the installation work relatively easily, saving installation time and labor costs. Moreover, there is no need to perform operations such as knocking on the components that may cause damage. The installation can be completed only through the splicing and cooperation of the frames, greatly reducing the possibility of damage to the components caused by installation operations, better protecting the integrity of the photovoltaic modules, and ensuring their long-term stable power generation performance and long service life.

[0036] Among them, the guiding grooves opened on the side walls of the bumps of the lower splicing block cooperate with the guiding columns installed on the side walls of the bumps of the upper splicing block, playing an accurate guiding role during the splicing process to ensure that adjacent frames can be accurately aligned and spliced. This guiding structure makes the installation process more standardized and accurate, avoiding problems such as loose frame connection or uneven component installation caused by installation deviation, and ensuring the installation quality and overall aesthetics of the photovoltaic modules.

[0037] Among them, after the installation of the guiding grooves and guiding columns, it can ensure the longitudinal limit between the lower splicing block and the upper splicing block, and the splicing and installation between different metal frames can achieve the transverse limit between the two. Longitudinally, the cooperative installation of the guiding grooves and guiding columns can ensure the precise docking between the lower splicing block and the upper splicing block, preventing them from displacing or shaking in the vertical direction. This limiting mechanism helps to maintain the overall structural stability of the photovoltaic module, ensuring that it can work properly under various environmental conditions. Transversely, the splicing and installation between different metal frames achieve their tight connection. This connection method not only enhances the connection strength between the frames but also prevents the frames from moving relative to each other in the horizontal direction. This transverse limit helps to maintain the flatness and overall rigidity of the photovoltaic module, further improving its wind resistance, snow load resistance and other capabilities.

[0038] Among them, the hollow design makes the main parts of the lower splicing block and the upper splicing block lighter. This can not only reduce the material usage and production costs but also help to reduce the weight during transportation and installation, improve the operation efficiency, and reduce the consumption of human and material resources. Secondly, the internal triangular support frame provides the necessary stability for the structure. As one of the most stable geometric shapes, the triangle can effectively resist external pressure and deformation, ensuring that the lower splicing block and the upper splicing block can maintain a tight connection state after splicing. Through this design, the entire structure can maintain stable performance in harsh environments, is not easily affected by external factors, and thus extends the service life.

[0052] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0053] It should be noted that the structures and working principles of devices such as the above-mentioned metal frame 1 and glass sheet 11 belong to the prior art and will not be elaborated here.

[0054] Embodiment 1: Please refer to Figures 1 to 3 As shown in the figure, a high light transmittance photovoltaic module includes a metal frame 1. A glass sheet 11 is installed inside the metal frame 1. An optical efficiency optimization mechanism 2 is arranged inside the metal frame 1. The optical efficiency optimization mechanism 2 is used to reduce the covering layer inside the metal frame 1 so as to improve the overall light transmittance.

[0055] Please refer to Figures 3 to 7 As shown in the figure, the optical efficiency optimization mechanism 2 includes a photovoltaic panel 21 installed inside the metal frame 1. Elastic plate clips 22 are evenly installed below the photovoltaic panel 21. Battery cells 23 are installed inside the elastic plate clips 22. A backplane 26 is installed below the battery cells 23.

[0056] It should be noted that the photovoltaic panel 21 is integrally in a grid shape. Installation grooves are formed at positions corresponding to the battery cells 23 below the photovoltaic panel 21. The photovoltaic panel 21 and the elastic plate clips 22 are movably connected through the installation grooves. Wires are arranged inside the solid frame parts of the elastic plate clips 22. The battery cells 23 are all installed at the positions of the solid frame of the lower frame of the photovoltaic panel 21. The photovoltaic panel 21 and the battery cells 23 are connected by flexible circuits, so as to make full use of the space, increase the light penetration path while ensuring the power generation area. The photovoltaic panel 21 and the battery cells 23 are all installed vertically. An inclined panel 24 is installed between every two adjacent battery cells 23. The inclined panel 24 is fixedly connected to the photovoltaic panel 21, and the tip of the inclined panel 24 faces downward. Limiting interlayers 28 are symmetrically and fixedly connected to the side walls of the metal frame 1. Buffer pads 25 are evenly installed inside the limiting interlayers 28 corresponding to the side walls of the photovoltaic panel 21. The buffer pads 25 are integrally in a corrugated shape, and both ends of the buffer pads 25 are fixedly connected to the side walls of the metal frame 1 and the photovoltaic panel 21 respectively. Arc-shaped protrusions 27 are evenly installed above the backplane 26, and the arc-shaped protrusions 27 are all located between adjacent battery cells 23.

[0057] Specifically, since installation grooves are formed below the photovoltaic panel 21, when installing the battery cells 23, the individual battery cells 23 can be installed in correspondence with the installation grooves and limited by the elastic plate clips 22. Through this installation method, after the installation is completed, the photovoltaic panel 21 and the multiple battery cells 23 are all in a vertical state, ensuring that more light can penetrate the module and directly irradiate indoors.

[0058] The arc-shaped protrusion 27 has a specific radius of curvature and can focus the incident light onto a specific area. According to the law of reflection of light, the angle of incidence is equal to the angle of reflection. This enables the arc-shaped protrusion 27 to reflect the light that is not directly absorbed by the solar cell 23 to the surface of the solar cell 23, thereby making up for the light absorption of the vertically installed solar cell 23. Moreover, the arc-shaped protrusion 27 made of a transparent mirror material uses an optical material with a high light transmittance, namely, polycarbonate optical material of optical grade PC material, to ensure that the loss of light during reflection is minimized. This allows only a small amount of energy to be absorbed or scattered when the light passes through the arc-shaped protrusion 27, and most of the light is effectively reflected to the solar cell 23.

[0059] The limiting interlayer 28 tightly fixes the photovoltaic panel 21 to the metal frame 1, preventing the photovoltaic panel 21 from shifting or shaking during installation or use. Then, by using the corrugated cushion 25, it contacts the side walls of the metal frame 1 and the photovoltaic panel 21, thereby reducing loosening or deformation caused by local stress concentration. Therefore, when the metal frame 1 is subjected to an external impact, the cushion 25 can absorb and disperse the impact energy through deformation, reducing the direct impact of the external force on the photovoltaic panel 21.

[0060] Embodiment 2: On the basis of Embodiment 1, please refer to Figures 8 to 12 As shown, a quick assembly mechanism 3 is provided outside the metal frame 1. The quick assembly mechanism 3 is used to quickly adjust the installation positions between different metal frames 1 and quickly install different metal frames 1. The quick assembly mechanism 3 includes a lower fitting block 31 and an upper fitting block 33 installed on the side wall of the metal frame 1. A through groove 35 is formed inside the upper fitting block 33, and a sliding shaft 36 is slidably connected inside the through groove 35. A magnetic piece cap 37 is installed at the end of the sliding shaft 36.

[0061] It should be noted that both the side of the lower fitting block 31 and the side of the upper fitting block 33 facing each other are alternately provided with protrusions and grooves. Guide grooves 32 are formed on the side walls of the protrusions in the lower fitting block 31, and guide posts 34 are installed on the side walls of the protrusions in the upper fitting block 33. The protrusion parts in the lower fitting block 31 and the upper fitting block 33 are both designed in a hollow shape. Support frames 38 are installed inside the protrusions in the lower fitting block 31 and the upper fitting block 33. The magnetic piece cap 37 has the same inner diameter size as the through groove 35. The sliding shaft 36 is threadedly connected to the magnetic piece cap 37, and the magnetic piece cap 37 is entirely made of a magnet material.

[0062] Specifically, since the lower fitting blocks 31 and the upper fitting blocks 33 are installed on the side walls of different metal frames 1, and the grooves and protrusions in the lower fitting blocks 31 and the upper fitting blocks 33 are designed in an alternating form, when assembling the metal frames 1, only by aligning and moving the guide grooves 32 on the side wall of the lower fitting block 31 with the guide posts 34 on the side wall of the upper fitting block 33 can the quick preliminary installation between different metal frames 1 be achieved.

[0063] After the initial installation is completed, the staff manually moves the sliding shaft 36 inside the through groove 35 outwards. Since a simple piston structure is formed between the through groove 35 and the sliding shaft 36, when the sliding shaft 36 is moved outwards, the space between the magnetic disc cap 37 and the through groove 35 will gradually increase. At this time, the air pressure inside the through groove 35 is less than the air pressure outside the through groove 35, thereby generating a suction force between the magnetic disc cap 37 and the through groove 35. Through this suction force, the air in the gap between the lower splicing block 31 and the upper splicing block 33 can be guided out, thereby enhancing the connection stability between the frames by using atmospheric pressure and reducing the risk of component shaking or displacement caused by frame loosening.

[0064] Since the sliding shaft 36 is threadedly connected to the arc protrusion 27 and the magnetic disc cap 37 is entirely made of a magnet material, after the sliding shaft 36 is completely removed from the inside of the through groove 35, the sliding shaft 36 is rotated to separate it from the magnetic disc cap 37, and the separated magnetic disc cap 37 will be adsorbed inside the upper splicing block 33 to cover the through groove 35 to ensure tightness.

[0065] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
