Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a connector, installation mechanism, and photovoltaic system for a photovoltaic module. Background Technology

[0002] In photovoltaic power plants, photovoltaic modules are usually arranged in an array, and connectors are set between adjacent photovoltaic modules to fix the photovoltaic modules to the photovoltaic support.

[0003] like Figure 1 The diagram shows a structural schematic of a photovoltaic module connector in the prior art. The connector includes a U-shaped fixing plate 1′ and pressure plates 2′ connected to both ends of the U-shaped fixing plate 1′. The two pressure plates 2′ extend in a direction away from each other. The U-shaped fixing plate 1′ is placed between two adjacent photovoltaic modules and can be connected to the photovoltaic bracket by fasteners. The pressure plates 2′ press and fix the photovoltaic modules on the photovoltaic bracket.

[0004] The existing technology has the following drawbacks: the connectors only serve to fix the photovoltaic modules to the photovoltaic bracket. Due to the presence of the connectors, there are large gaps between adjacent photovoltaic modules. Solar energy cannot be absorbed and converted into electricity in these gaps, resulting in wasted solar energy. In the entire photovoltaic array, the total area of ​​these gaps is considerable, and their inability to capture light leads to significant energy loss in the photovoltaic power station, which is detrimental to improving the power generation efficiency and output of the photovoltaic power station.

[0005] Therefore, there is an urgent need for a photovoltaic module connector, installation mechanism, and photovoltaic system to solve the aforementioned problems in the existing technology. Utility Model Content

[0020] As an optional solution for the connector of the photovoltaic module provided by this utility model, the first end of the fixing plate is connected to the second end of the first reflective part, and the second end of the fixing plate is connected to the second end of the second reflective part;

[0021] Alternatively, the fixing structure may further include a connecting plate, which is connected to the first end of the first reflective part and the first end of the second reflective part through the connecting plate, and there is a gap between the fixing plate and the second end of the first reflective part, and between the fixing plate and the second end of the second reflective part.

[0030] The beneficial effects of this utility model are:

[0031] This invention provides a connector, mounting mechanism, and photovoltaic system for photovoltaic modules. In the photovoltaic system, adjacent photovoltaic modules are fixed to a photovoltaic bracket via connectors. By setting a first reflective surface and a second reflective surface on the connector, with both surfaces forming an angle with the surface of the corresponding photovoltaic module, when light shines on the first and second reflective surfaces, the light can be effectively reflected onto the light-receiving surface of the photovoltaic module. This redirects light that might otherwise have been directed to non-light-receiving areas or lost to the photovoltaic module's cells. Through this optical reflection gain, the amount of light captured per unit area of ​​the entire photovoltaic system can be significantly increased, thereby effectively improving the photoelectric conversion efficiency of the photovoltaic module. Furthermore, this connector design, without increasing the overall area of ​​the photovoltaic system or the area of ​​the photovoltaic module's cells, fully utilizes the light energy resources at the gaps between photovoltaic modules, reduces energy loss, and further improves the overall power generation efficiency and output of the system, maximizing power output within a limited installation area.

[0032] In addition, since the first and second reflective surfaces are connected at the end furthest from the photovoltaic module, the overall strength of the connector is increased, preventing deformation and damage. Furthermore, the seamless connection between the first and second reflective surfaces ensures that the gaps between adjacent photovoltaic modules are sealed, providing protection against water and dust accumulation, extending the lifespan of the connector, and ensuring the long-term stable and reliable power generation of the photovoltaic system.

[0056] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0057] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0058] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0059] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0060] In this embodiment, the term "and / or" is merely a description of the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this invention, the character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0061] In the embodiments of this utility model, the same reference numerals denote the same parts, and for the sake of brevity, detailed descriptions of the same parts are omitted in different embodiments.

[0062] like Figure 2 , Figure 3 as well as Figure 4 As shown, this embodiment provides a connector 10 for fixing adjacent photovoltaic modules 100 to a photovoltaic support 20. This connector 10 can fully utilize the light rays in the gaps between adjacent photovoltaic modules 100, reduce energy loss, and improve the power generation efficiency and output of the photovoltaic system.

[0063] Among them, combined Figure 4 , Figure 5 as well as Figure 6 The connector 10 includes a reflective structure 1, which has a first reflective surface 111 and a second reflective surface 121 arranged at an angle. The first end of the first reflective surface 111 and the first end of the second reflective surface 121 are connected, and the second end of the first reflective surface 111 and the second end of the second reflective surface 121 extend toward adjacent photovoltaic modules 100, respectively. Both the first reflective surface 111 and the second reflective surface 121 are arranged at an angle to the surface of the corresponding photovoltaic module 100.

[0064] In the photovoltaic system, adjacent photovoltaic modules 100 are fixed to the photovoltaic bracket 20 via the connector 10 provided in this embodiment. By providing a first reflective surface 111 and a second reflective surface 121 on the connector 10, and setting the first reflective surface 111 and the second reflective surface 121 at an angle to the surface of the corresponding photovoltaic module 100, when light shines on the first reflective surface 111 and the second reflective surface 121, the first reflective surface 111 and the second reflective surface 121 can effectively reflect the light onto the light-receiving surface of the photovoltaic module 100, thereby redirecting the light that might have been irradiated to the non-light-receiving area or lost to the cells of the photovoltaic module 100. Through this optical reflection gain, the amount of light captured per unit area of ​​the entire photovoltaic system can be significantly improved, thereby effectively improving the photoelectric conversion efficiency of the photovoltaic module 100. Furthermore, the design of the connector 10, without increasing the overall area of ​​the photovoltaic system or the area of ​​the photovoltaic module 100's own cells, makes full use of the light energy resources at the gaps between the photovoltaic modules 100, reduces energy loss, and further improves the overall power generation efficiency and power output of the system, thereby maximizing power output within a limited installation area.

[0065] In addition, since the first reflective surface 111 and the second reflective surface 121 are connected at the end away from the photovoltaic module 100, on the one hand, the overall strength of the connector 10 is higher, avoiding deformation and damage. On the other hand, since the first reflective surface 111 and the second reflective surface 121 are connected without gaps, the gap between adjacent photovoltaic modules 100 is kept closed, which provides a certain degree of protection for the gap, prevents water and dust accumulation, extends the service life of the connector 10, and helps to ensure the long-term stable and reliable power generation of the photovoltaic system.

[0066] In two adjacent photovoltaic modules 100, the first reflective surface 111 of the connector 10 corresponds to one of the photovoltaic modules 100 and is set at an obtuse angle to the upper surface (light-receiving surface) of that photovoltaic module 100; the second reflective surface 121 corresponds to the other photovoltaic module 100 and is set at an obtuse angle to the upper surface (light-receiving surface) of that photovoltaic module 100. See details. Figure 7 The reflection path of light after it hits the second reflective surface 121 is shown by the dashed arrow. After the incident light hits the second reflective surface 121, it is reflected onto the light-receiving surface of the photovoltaic module 100 corresponding to the second reflective surface 121, so that the photovoltaic module 100 captures this part of the light energy.

[0067] In some embodiments of the connector 10, the angle between the first reflective surface 111 and the surface of the corresponding photovoltaic module 100 is 120° to 150°. This angle range limits the angle between the first reflective surface 111 and the light-receiving surface of the photovoltaic module 100 to prevent excessive shading of the light-receiving surface, and also prevents the angle from being too small to ensure proper reflection of light onto the corresponding photovoltaic module 100. For example, the angle between the first reflective surface 111 and the surface of the corresponding photovoltaic module 100 can be set to 120°, 125°, 130°, 135°, 140°, 145°, 150°, or angles between adjacent values, but is not limited to the listed values ​​and ranges.

[0068] In some embodiments of the connector 10, the angle between the second reflective surface 121 and the surface of the corresponding photovoltaic module 100 is 120° to 150°. This angle range limits the angle between the second reflective surface 121 and the light-receiving surface of the photovoltaic module 100 to prevent excessive shading of the light-receiving surface, and also prevents the angle from being too small to ensure proper reflection of light onto the corresponding photovoltaic module 100. For example, the angle between the second reflective surface 121 and the surface of the corresponding photovoltaic module 100 can be set to 120°, 125°, 130°, 135°, 140°, 145°, 150°, or angles between adjacent values, but is not limited to the listed values ​​and ranges.

[0069] Optionally, the first reflective surface 111 and the second reflective surface 121 are arranged in a mirror symmetry, and the angle between the first reflective surface 111 and the second reflective surface 121 and the surface of the corresponding photovoltaic module 100 is the same.

[0070] In some embodiments, a reflective film layer may be added to the first reflective surface 111 and the second reflective surface 121 to reflect more light that is irradiated between adjacent photovoltaic modules 100 onto the surface of the photovoltaic module 100, thereby further increasing the amount of light captured by the photovoltaic module 100 and improving the power generation efficiency.

[0071] For example, the reflective film layer can be a transparent PET reflective film, a white EVA film with high reflectivity, etc., without specific limitations.

[0072] In some embodiments, the connector 10 of the photovoltaic module 100 is a hollow structure, which can reduce the weight of the connector 10 while ensuring its strength, reduce the material used in the connector 10, and reduce costs.

[0073] Specifically, such as Figure 4 , Figure 5 as well as Figure 6 As shown, the reflective structure 1 includes a first reflective portion 11 and a second reflective portion 12. Along the direction away from the photovoltaic module 100, the first reflective portion 11 and the second reflective portion 12 are gradually inclined towards each other, so that both the first reflective surface 111 and the second reflective surface 121 form an obtuse angle with the corresponding light-receiving surface of the photovoltaic module 100, thereby effectively reflecting light onto the photovoltaic module 100. The first end of the first reflective portion 11 and the first end of the second reflective portion 12 are connected, and the second end of the first reflective portion 11 and the second end of the second reflective portion 12 are pressed against the photovoltaic module 100. The first reflective surface 111 is located on the first reflective portion 11, and the second reflective surface 121 is located on the second reflective portion 12. Because the first ends of the first reflective portion 11 and the first ends of the second reflective portion 12 are connected to each other, the overall strength of the connector 10 is ensured, and the gap between adjacent photovoltaic modules 100 is covered, providing good sealing and protection for that gap.

[0074] Of course, in other embodiments, the connector 10 of the photovoltaic module 100 can also be a solid structure, as long as a first reflective surface 111 and a second reflective surface 121 are provided on both sides.

[0075] Continue reading Figure 4 , Figure 5 as well as Figure 6 In some embodiments, the reflective structure 1 further includes a connecting portion 13, through which the first reflective portion 11 and the second reflective portion 12 are connected; the connecting portion 13 is provided with a connecting surface 131, through which the first reflective surface 111 is connected to the second reflective surface 121. Connecting the first reflective portion 11 and the second reflective portion 12 via the connecting portion 13 avoids the formation of sharp corners at the intersection of the first reflective portion 11 and the second reflective portion 12.

[0076] For example, the connecting part 13 is parallel to the surface of the photovoltaic module 100, so that the side of the connector 10 facing away from the photovoltaic module 100 (connecting surface 131) is flat, which facilitates the storage and transportation of the connector 10 and also provides higher safety during installation.

[0077] In some other embodiments, the connecting part 13 may be omitted, and the first end of the first reflective part 11 and the first end of the second reflective part 12 may be directly connected. The first reflective surface 111 and the second reflective surface 121 may be directly connected to form a sharp corner, which can also reflect light to the light-receiving surface of the photovoltaic module 100.

[0078] like Figure 2 As shown, for ease of description, a first direction, a second direction, and a third direction are defined and explained. The first and second directions are the extension directions of adjacent sides of the photovoltaic module 100, respectively. The third direction is the thickness direction of the photovoltaic module 100. The arrangement direction of adjacent photovoltaic modules 100 is the first direction. The first, second, and third directions are perpendicular to each other.

[0079] like Figure 7 As shown, the maximum dimension of the connecting portion 13 along the first direction is L1, and the maximum distance between the first reflecting portion 11 and the second reflecting portion 12 along the first direction is L2. L1 is less than L2, and the ratio of L1 to L2 is greater than or equal to 1 / 6 and less than or equal to 1 / 2. When the tilt angles of the first reflecting surface 111 and the second reflecting surface 121 are constant, this limited range of ratios prevents the dimension L1 of the connecting portion 13 from becoming too large, resulting in a reduction in the area of ​​the first reflecting surface 111 and the area of ​​the second reflecting surface 121, ensuring that the connector 10 has sufficient reflective area to reflect light. Simultaneously, this limited range of ratios prevents the dimension L1 of the connecting portion 13 from becoming too small, resulting in a larger dimension of the connector 10 along the third direction, saving space occupied by the connector 10 and facilitating storage and transportation.

[0080] like Figure 4 , Figure 5 as well as Figure 6 As shown, the connector 10 also includes a fixing structure 2, which is connected to the reflective structure 1. The fixing structure 2 is used to connect to the photovoltaic bracket 20 via fasteners 30, so that the connector 10 presses the photovoltaic module 100 onto the photovoltaic bracket 20. The fixing structure 2 provides a connection base for the fasteners 30, enabling the installation of the photovoltaic module 100 on the photovoltaic bracket 20.

[0081] For example, fastener 30 includes screws or bolts for threaded connection to fix structure 2 and photovoltaic bracket 20.

[0082] Optionally, the fixing structure 2 includes a fixing plate 21, which is used to connect with fasteners 30 and press against the photovoltaic module 100. The fasteners 30 pass through the fixing plate 21 and connect to the photovoltaic bracket 20, clamping the photovoltaic module 100 between the fixing plate 21 and the photovoltaic bracket 20. The fixing plate 21 has a large contact area with the photovoltaic module 100, which improves the installation stability of the photovoltaic module 100.

[0083] In some embodiments, such as Figure 6 As shown, the first end of the fixing plate 21 is connected to the second end of the first reflective part 11, and the second end of the fixing plate 21 is connected to the second end of the second reflective part 12, thereby realizing the connection between the fixing structure 2 and the reflective structure 1, and ensuring the strength and stability of the fixing plate 21, and avoiding large deformation when fasteners 30 are inserted.

[0084] In other embodiments, such as Figure 8 , Figure 9 as well as Figure 10 As shown, in this embodiment, the fixing structure 2 of the connector 10 further includes a connecting plate 22. The fixing plate 21 is connected to the first end of the first reflective part 11 and the first end of the second reflective part 12 through the connecting plate 22. There is a gap between the fixing plate 21 and the second end of the first reflective part 11, and between the fixing plate 21 and the second end of the second reflective part 12. More specifically, the upper end of the connecting plate 22 is connected to the connecting part 13, realizing the connection with the first ends of both the first reflective part 11 and the second reflective part 12. The lower end of the connecting plate 22 is connected to the upper surface of the fixing plate 21, which can also realize a stable connection between the fixing structure 2 and the reflective structure 1.

[0085] exist Figure 6 and Figure 10 In the embodiment shown, a limiting part 23 is protruding on the fixing plate 21. The limiting part 23 is engaged between adjacent photovoltaic modules 100, which can limit the spacing between adjacent photovoltaic modules 100 and improve the installation stability of photovoltaic modules 100.

[0086] In some embodiments, such as Figure 5 and Figure 6 As shown, a groove 24 is recessed on the side of the fixing plate 21 facing away from the limiting part 23. While the groove 24 is formed on one side of the fixing plate 21, the limiting part 23 can be formed protruding on the other side of the fixing plate 21. For example, the connector 10 can be integrally formed by processes such as rolling and extrusion.

[0087] like Figure 2 and Figure 11 As shown, the connector 10 extends in a strip shape, specifically along the second direction, thereby pressing the entire side of the photovoltaic module 100 onto the photovoltaic bracket 20, improving the installation stability of the photovoltaic module 100.

[0088] like Figure 11 and Figure 12As shown, the fixing plate 21 has a first through hole 211, and the reflective structure 1 has a second through hole 14. The fastener 30 can pass through the second through hole 14 into the first through hole 211 and connect to the photovoltaic bracket 20. By providing the second through hole 14, space is made for the fastener 30 to pass through the first through hole 211 and connect to the photovoltaic bracket 20 by threads. Specifically, the second through hole 14 and the first through hole 211 are arranged facing each other in the third direction to facilitate the fastener 30 to pass through.

[0089] This embodiment also provides an installation mechanism for a photovoltaic module 100, including the connector 10 for the photovoltaic module 100 as described above. This installation mechanism enables the installation and fixing of the arrayed photovoltaic modules 100. Specifically, the installation mechanism further includes a fastener 30 and a photovoltaic bracket 20. The connector 10 is connected to the photovoltaic bracket 20 via the fastener 30, and the photovoltaic module 100 is pressed tightly against the photovoltaic bracket 20.

[0090] Because this mounting mechanism includes the aforementioned connector 10, when light shines on the first reflective surface 111 and the second reflective surface 121, the first reflective surface 111 and the second reflective surface 121 can effectively reflect the light onto the light-receiving surface of the photovoltaic module 100. This redirects light that might otherwise have been directed to non-light-receiving areas or lost back to the cells of the photovoltaic module 100. Through this optical reflection gain, the amount of light captured per unit area of ​​the entire photovoltaic system can be significantly increased, thereby effectively improving the photoelectric conversion efficiency of the photovoltaic module 100. Furthermore, this mounting mechanism ensures that the light energy resources at the gaps between the photovoltaic modules 100 are fully utilized without increasing the overall area of ​​the photovoltaic system or the area of ​​the photovoltaic module 100's own cells, reducing energy loss and further improving the overall power generation efficiency and output of the system, maximizing power output within a limited installation area.

[0091] This embodiment also provides a photovoltaic system, including a photovoltaic module 100 and a mounting mechanism for the photovoltaic module 100 as described above. (See reference...) Figure 2 Adjacent photovoltaic modules 100 are fixed to the photovoltaic bracket 20 by connectors 10 and fasteners 30. The connectors 10 extend in a strip shape along the edge of the photovoltaic module 100, ensuring that the entire side area of ​​the photovoltaic module 100 extending in the second direction is stably pressed, thus guaranteeing the secure installation of the photovoltaic module 100. This photovoltaic system can fully utilize the light in the gaps between adjacent photovoltaic modules 100, reduce energy loss, and improve the power generation efficiency and output of the photovoltaic system.

[0092] Photovoltaic systems can be applied in photovoltaic power plants, such as ground-mounted, rooftop, and floating power plants, as well as in equipment or devices that utilize solar energy to generate electricity, such as user solar power supplies, solar streetlights, solar cars, and solar buildings. Of course, it's understandable that the application scenarios of photovoltaic systems are not limited to these; that is, photovoltaic systems can be applied in all fields that require solar energy to generate electricity. Taking a photovoltaic power generation network as an example, a photovoltaic system can include photovoltaic arrays, combiner boxes, and inverters. A photovoltaic array can be a combination of multiple battery modules; for example, multiple battery modules can form multiple photovoltaic arrays. The photovoltaic arrays are connected to combiner boxes, which collect the current generated by the photovoltaic arrays. The collected current flows through an inverter and is converted into AC power required by the mains grid before being connected to the mains grid to achieve solar power supply.

[0093] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
