[0002] Photovoltaic modules can be installed on buildings such as rooftops, converting solar energy into electricity to meet the building's needs. Currently, the reliability of photovoltaic module installations is relatively low, which affects their normal operation. Summary of the Invention

[0003] In view of this, this application provides a photovoltaic component to help solve the problem of low reliability in the installation of photovoltaic modules in the prior art.

[0004] This application provides a photovoltaic component, including a clamp and a photovoltaic module. A fixing member is fixedly connected to one side of the clamp. The photovoltaic module includes a laminate and a frame. The laminate has a backlight surface along a first direction. The frame is fixedly connected to the backlight surface. The frame is movably connected to the fixing member. The fixing member can abut against the frame to limit the position of the frame in the first direction.

[0005] In one possible implementation, the frame includes a first body portion and a second body portion connected to each other, with a cavity between the first body portion and the second body portion, and the fastener includes a hook-shaped portion located within the cavity, the hook-shaped portion being movably connected to the first body portion.

[0006] In one possible implementation, the hook-shaped portion has a receiving space, a first end of the first body portion is located within the receiving space, the first end is rotatable within the receiving space so that the frame can rotate relative to the fixing member, and the first end is abutting against the inner wall of the receiving space to limit the position of the frame in the first direction.

[0007] In one possible implementation, the second body portion has a protrusion that protrudes into the cavity and abuts against the hook-shaped portion to limit the position of the frame in the second direction.

[0008] In one possible implementation, the photovoltaic component further includes a pressure block stacked on the side of the fixing member away from the clamp along the first direction. The pressure block, the fixing member, and the clamp are fixedly connected by fasteners. The end of the pressure block extends toward the frame and can abut against the outer surface of the frame to limit the position of the frame in the second direction.

[0009] In one possible implementation, the thickness of the fastener gradually decreases in the direction away from the clamp.

[0010] In one possible implementation, the fastener includes a connecting portion connected to the clamp, a hook-shaped portion connected to both ends of the connecting portion, and the hook-shaped portion being movably connected to the frame of the corresponding photovoltaic module.

[0011] In one possible implementation, the connecting portion has a first limiting protrusion and a second limiting protrusion spaced apart from each other, a limiting space between the first limiting protrusion and the second limiting protrusion, a portion of the clamp structure being located within the limiting space, and the first limiting protrusion and the second limiting protrusion respectively abutting against the clamp.

[0012] In one possible implementation, the fastener includes a first sub-fastener and a second sub-fastener stacked along the first direction, the first sub-fastener and the second sub-fastener being detachably connected, the hook-shaped portions being located at the ends of the first sub-fastener and the second sub-fastener being located at the ends of the second sub-fastener and the first sub-fastener respectively, and the hook-shaped portions being movably connected to the frame of the corresponding photovoltaic module.

[0014] This application provides a photovoltaic component, including a clamp and a photovoltaic module. A fixing member is fixedly connected to one side of the clamp. The photovoltaic module includes a laminate and a frame. The laminate has a backlight surface along a first direction. The frame is fixedly connected to the backlight surface and movably connected to the fixing member. The fixing member can abut against the frame to restrict the position of the frame in the first direction. By movably connecting the fixing member and the frame, the frame can move relative to the fixing member when the photovoltaic module is subjected to external force. This reduces the possibility of stress concentration and breakage at the connection point between the frame and the fixing member when the photovoltaic module is subjected to external force, thereby improving the reliability of photovoltaic module installation and extending the service life of the photovoltaic module. At the same time, the fixing member also limits the position of the frame, thereby restricting the position of the photovoltaic module in the first direction, reducing the possibility of large-scale shaking of the photovoltaic module in the first direction, improving the stability and reliability of photovoltaic module installation, and thus improving the overall reliability of the photovoltaic component.

[0030] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0031] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0032] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0033] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related 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, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0034] like Figure 1 As shown, this application embodiment provides a photovoltaic component, including a clamp 1 and a photovoltaic module 3. A fixing member 2 is fixedly connected to one side of the clamp 1. The photovoltaic module 3 includes a laminate 31 and a frame 32. The laminate 31 has a backlight surface 31a along the first direction Z. The frame 32 is fixedly connected to the backlight surface 31a. The frame 32 is movably connected to the fixing member 2. The fixing member 2 can abut against the frame 32 to limit the position of the frame 32 in the first direction Z.

[0035] The fixing member 2 is fixedly connected to one side of the clamp 1 along the first direction Z, and the fixing member 2 can extend outward along the second direction X towards the clamp 1. Both ends of the fixing member 2 along the second direction X can be movably connected to the frame 32 of the photovoltaic module 3. That is, in the second direction X, two adjacent photovoltaic modules 3 can be connected by the fixing member 2, and these two adjacent photovoltaic modules 3 are connected to the clamp 1 through the fixing member 2. The photovoltaic module 3 can convert solar energy into electrical energy. Along the first direction Z, the laminate 31 has a light-receiving surface 31b and a back-lighting surface 31a. The light-receiving surface 31b is the surface of the laminate 31 that receives sunlight, and the back-lighting surface 31a is the surface of the laminate 31 that is away from sunlight. The frame 32 is fixed to the back-lighting surface 31a, and the frame 32 can be set at the edge of the back-lighting surface 31a. The frame 32 improves the structural strength of the photovoltaic module 3, reducing the possibility of damage caused by external forces during transportation, installation, and use, thus extending the lifespan and improving the reliability of the photovoltaic module 3. Simultaneously, placing the frame 32 on the backlight surface 31a of the laminate 31 reduces the possibility of the frame 32 obstructing the light-receiving surface 31b of the laminate 31, thereby reducing the shading area and improving the efficiency of the photovoltaic module 3.

[0036] During the use of photovoltaic components, the photovoltaic module 3 will deform under external forces (such as wind). For example, under external forces, the middle area of ​​the photovoltaic module 3 will bulge relative to the edge area in the direction of the external force. At this time, the frame 32 set at the edge of the photovoltaic module 3 will tend to rotate relative to the fixing member 2. If the frame 32 is fixedly connected to the fixing member 2, even if the frame 32 cannot move, stress concentration is likely to occur in the edge area of ​​the photovoltaic module 3, which will lead to the photovoltaic module 3 breaking and being damaged, affecting the normal use of the entire photovoltaic component. Based on this, the embodiment of this application connects the fixing member 2 and the frame 32 movably, so that the frame 32 can move relative to the fixing member 2 when the photovoltaic module 3 is subjected to external forces. This reduces the possibility of stress concentration and breakage of the photovoltaic module 3 at the connection point between the frame 32 and the fixing member 2 when the photovoltaic module 3 is subjected to external forces, thereby improving the reliability of the photovoltaic module 3 installation and extending the service life of the photovoltaic module 3. At the same time, the fastener 2 also limits the frame 32. Specifically, the fastener 2 can abut against the frame 32 along the first direction Z to limit the position of the frame 32 in the first direction Z, reduce the possibility of the frame 32 disengaging from the fastener 2, and improve the stability and reliability of the connection between the frame 32 and the fastener 2. Since the position of the photovoltaic module 3 in the first direction Z is limited, the possibility of the photovoltaic module 3 shaking significantly in the first direction Z is reduced, thereby improving the stability of the photovoltaic module 3 installation and improving the overall reliability of the photovoltaic component.

[0037] The laminate 31 contains solar cells, including but not limited to the following types: Passivated Emitter Rear Cell (PERC), Tunnel Oxide Passivated Contact (TOPCon), Heterojunction with Intrinsic Thin-film (HJT), Interdigitated Back Contact (IBC), and perovskite solar cells.

[0038] For PERC cells, along their thickness direction, the PERC cell sequentially includes a front-surface silver electrode, a front-surface silicon nitride passivation layer, a phosphorus emitter layer, a P-type substrate silicon layer, a localized aluminum back field, a metallic aluminum back electrode, and a back passivation layer (Al2O3 / SiNx). PERC cells use a passivation film to passivate the back side, replacing the all-aluminum back field, enhancing light reflection within the silicon substrate, reducing the recombination rate on the back side, and improving the cell efficiency by 0.5%-1%.

[0039] For a TOPCon cell, along its thickness direction, it sequentially comprises a silver electrode, a front-surface silicon nitride passivation layer, a boron-doped emitter, an N-type substrate silicon layer, a diffused doped layer, an ultrathin silicon oxide layer, doped polycrystalline silicon, silicon nitride, and the silver electrode. The back of the cell consists of an ultrathin silicon oxide layer (1nm–2nm) and a phosphorus-doped microcrystalline amorphous mixed Si film, which together form a passivation contact structure. This structure blocks minority carrier recombination, increasing the cell's open-circuit voltage and short-circuit current. The ultrathin oxide layer allows majority carrier electrons to tunnel into the polycrystalline silicon layer while simultaneously blocking minority carrier recombination. The excellent passivation effect of the ultrathin silicon oxide and heavily doped silicon film causes band bending on the silicon wafer surface, creating a field passivation effect. This significantly increases the probability of electron tunneling, reduces contact resistance, and improves the cell's open-circuit voltage and short-circuit current, thereby enhancing the cell's conversion efficiency.

[0040] For an HJT cell, along its thickness direction, the HJT cell sequentially includes a front low-temperature silver electrode, a front conductive film, an N-type amorphous silicon film, an intrinsic amorphous silicon film, an N-type substrate silicon layer, an intrinsic amorphous silicon film, a P-type amorphous silicon film, a back conductive film, and a back low-temperature silver electrode.

[0041] For an IBC cell, along its thickness direction, it sequentially includes a silicon nitride inversion layer, an N+ front surface field, an N-type substrate silicon layer, a P+ emitter, an N+ back field, an aluminum oxide passivation layer, a silicon nitride antireflection layer, and a silver electrode. IBC cells utilize ion implantation technology to obtain P- and N-regions with good uniformity and precisely controllable junction depth. The absence of grid lines on the front side eliminates light-blocking current loss from the metal electrodes, maximizing the utilization of incident photons and improving short-circuit current by approximately 7% compared to conventional solar cells. Due to its back-contact structure, grid line shading is not a concern, allowing for a wider grid line ratio, thus reducing series resistance and achieving a high fill factor. Optimized design of surface passivation and light-trapping structures can be achieved, resulting in lower front surface recombination rates and surface reflection.

[0042] For a perovskite solar cell, along its thickness direction, it sequentially comprises a substrate material, a conductive thin film, an electron transport layer (titanium dioxide), a perovskite absorption layer (hole transport layer), and a metal cathode. Perovskite materials possess a high light absorption coefficient and a long carrier diffusion distance. After the photons absorbed by the perovskite material are converted into electrons, they are easily collected by the electrodes with minimal loss, thus generating high photogenerated voltage and current, resulting in high photoelectric conversion efficiency.

[0043] like Figure 2 As shown, in one possible implementation, the frame 32 includes a first body portion 321 and a second body portion 322 that are connected to each other, and a cavity 323 is provided between the first body portion 321 and the second body portion 322. The fastener 2 includes a hook-shaped portion 21, which is located in the cavity 323 and is movably connected to the first body portion 321.

[0044] The first body portion 321 and the second body portion 322 can be arranged along the first direction Z, and the first body portion 321 and the second body portion 322 can be connected to form an approximate "C" shape. The cavity 323 has a first opening 3231, the direction of the first opening 3231 being along the second direction X towards the side opposite to the clamp 1. The hook-shaped portion 21 is also approximately "C" shaped, and the hook-shaped portion 21 extends into the cavity 323 through the aforementioned first opening 3231 and is movably connected to the first body portion 321. That is, the frame 32 and the hook-shaped portion 21 are interlocked, and the frame 32 can move relative to the hook-shaped portion 21. When the first body portion 321 abuts against the top of the hook-shaped portion 21 along the first direction Z, the hook-shaped portion 21 can limit the position of the frame 32, that is, limit the position of the photovoltaic module 3 in the first direction Z.

[0045] As mentioned above, the photovoltaic module 3 will deform under external force (such as wind), causing the frame 32 to tend to rotate relative to the fixing member 2. In this embodiment, the fixing member 2 is movably connected to the frame 32 through the hook-shaped part 21. Since the shape of the hook-shaped part 21 is approximately "C", it is convenient for the frame 32 to rotate relative to the fixing member 2, which facilitates the movable connection between the fixing member 2 and the frame 32. This reduces the possibility of stress concentration and breakage of the photovoltaic module 3 at the connection point between the frame 32 and the fixing member 2 when the photovoltaic module 3 is subjected to external force. At the same time, the hook-shaped part 21 limits the frame 32 to restrict the position of the photovoltaic module 3 in the first direction Z, reducing the possibility of large-scale shaking of the photovoltaic module 3 in the first direction Z, improving the stability of the photovoltaic module 3 installation, and thus improving the overall reliability of the photovoltaic component.

[0046] like Figure 2 As shown, in one possible implementation, the hook-shaped portion 21 has a receiving space 211, the first end portion 3211 of the first body portion 321 is located in the receiving space 211, the first end portion 3211 is rotatable in the receiving space 211 so that the frame 32 can rotate relative to the fixing member 2, and the first end portion 3211 can abut against the inner wall of the receiving space 211 to limit the position of the frame 32 in the first direction Z.

[0047] The receiving space 211 has a second opening 2111, the orientation of which is opposite to the orientation of the first opening 3231 of the cavity 323 of the frame 32. The first end portion 3211 of the first body portion 321 extends into the receiving space 211 through the second opening 2111. Along the first direction Z, the size of the receiving space 211 is larger than the size of the first end portion 3211, thereby providing space for the first end portion 3211 to move, so as to realize the rotational connection between the first body portion 321 and the hook portion 21. As mentioned above, the shape of the hook portion 21 is approximately "C" shaped, that is, the inner wall of the receiving space 211 has an arc-shaped surface. When the first end portion 3211 abuts against the inner wall of the receiving space 211, the hook portion 21 can limit the frame 32.

[0048] The hook-shaped part 21 provides space for the frame 32 to rotate, thereby realizing the rotational connection between the hook-shaped part 21 and the frame 32. Therefore, when the photovoltaic module 3 is deformed by external force, the frame 32 can rotate relative to the fixing member 2, thereby reducing the possibility of stress concentration and breakage of the photovoltaic module 3 at the connection position between the frame 32 and the fixing member 2, thus extending the service life of the photovoltaic module 3 and improving the overall reliability of the photovoltaic component. At the same time, the first end 3211 of the frame 32 can abut against the inner wall of the accommodating space 211, so that the hook-shaped part 21 plays a limiting role on the frame 32, reducing the possibility of the frame 32 disengaging from the fixing member 2, and reducing the possibility of the photovoltaic module 3 swaying significantly in the first direction Z, thereby improving the installation stability of the photovoltaic module 3.

[0049] In some embodiments, the first end 3211 has an arc structure 3211a, the shape of which can correspond to the shape of the hook portion 21, so as to facilitate the rotation of the first end 3211 in the receiving space 211 of the hook portion 21 and reduce the possibility of the first end 3211 getting stuck in the receiving space 211.

[0050] like Figure 2 As shown, in one possible implementation, the second body portion 322 has a protrusion 3221 that protrudes into the cavity 323, and the protrusion 3221 abuts against the hook-shaped portion 21 to limit the position of the frame 32 in the second direction X.

[0051] When the protrusion 3221 abuts against the hook-shaped portion 21, there can be a gap between the first end 3211 and the inner wall of the receiving space 211 along the second direction X, that is, the first end 3211 is not abutting against the inner wall of the receiving space 211 along the second direction X. During the installation of the frame 32 and the fastener 2, when the protrusion 3221 abuts against the hook-shaped portion 21, the frame 32 can no longer move towards the side closer to the hook-shaped portion 21 along the second direction X, so that the first end 3211 can maintain a certain distance from the inner wall of the receiving space 211, thereby providing space for the first end 3211 to rotate, so as to realize the rotational connection between the frame 32 and the hook-shaped portion 21. On the other hand, under the restriction of the protrusion 3221, the possibility of the frame 32 sliding off in the second direction X is reduced, thereby improving the stability and reliability of the photovoltaic module 3 installation.

[0052] In some embodiments, a protruding first abutting portion 27 is provided on the outer surface of the hook-shaped portion 21. The first abutting portion 27 can abut against the protrusion 3221 to limit the frame 32.

[0053] In some embodiments, the receiving space 211 of the hook-shaped portion 21 has a protruding second abutment portion 28, which can abut against the first end portion 3211 to limit the position of the first end portion 3211 in the receiving space 211. When the first end portion 3211 abuts against the second abutment portion 28, a certain distance is maintained between the first end portion 3211 and the inner wall of the receiving space 211, thereby providing a certain rotation space for the first end portion 3211 to realize the rotational connection between the frame 32 and the hook-shaped portion 21.

[0054] like Figure 1 and Figure 2 As shown, in one possible embodiment, the photovoltaic component further includes a pressure block 4, which is stacked on the side of the fixing member 2 away from the clamp 1 along the first direction Z. The pressure block 4, the fixing member 2 and the clamp 1 are fixedly connected by fasteners 5. The end of the pressure block 4 extends toward the frame 32 and can abut against the outer surface of the frame 32 to limit the position of the frame 32 in the second direction X.

[0055] When the pressure block 4 abuts against the outer surface of the frame 32, the pressure block 4 limits the frame 32, preventing the frame 32 from moving towards the side closer to the clamp 1 along the second direction X, thereby reducing the possibility of the frame 32 disengaging from the hook-shaped part 21 and improving the stability and reliability of the photovoltaic module 3 installation. As mentioned above, the second body part 322 may have a protrusion 3221. The protrusion 3221 and the pressure block 4 can respectively limit the position of the frame 32 on the inner and outer sides of the frame 32 to further improve the stability of the connection between the frame 32 and the fastener 2. The fastener 5 mentioned above may include a bolt 51 and a nut 52. The bolt 51 and the nut 52 cooperate to fix the pressure block 4, the fastener 2, and the clamp 1 together.

[0056] As mentioned above, both ends of the fastener 2 along the second direction X can be movably connected to the frame 32 of the corresponding photovoltaic module 3. Both ends of the pressure block 4 along the second direction X can extend toward the frame 32 of the corresponding photovoltaic module 3 to limit the position of the corresponding frame 32.

[0057] like Figure 1 and Figure 3As shown, in one possible implementation, the thickness of the fastener 2 gradually decreases in the direction away from the clamp 1. Specifically, the fastener 2 may include a connecting portion 22 and the aforementioned hook-shaped portion 21. Along the second direction X, the hook-shaped portion 21 is connected to at least one end of the connecting portion 22, and the thickness of the connecting portion 22 is greater than the thickness of the hook-shaped portion 21. By increasing the thickness of the connecting portion 22, the stability and reliability of the connection between the fastener 2 and the clamp 1 are improved, thereby facilitating a stable connection between the photovoltaic module 3 and the clamp 1. The hook-shaped portion 21 is located on the outside of the clamp 1 and can be considered as a cantilever structure. Therefore, by appropriately thinning the thickness of the hook-shaped portion 21, the overall structural strength of the fastener 2 can be improved, reducing the possibility of breakage and damage to the fastener 2, and further improving the reliability of the connection between the photovoltaic module 3 and the clamp 1.

[0058] like Figure 3 As shown, in one possible implementation, the fastener 2 includes a connecting part 22, which is connected to the clamp 1, and a hook-shaped part 21 is connected to both ends of the connecting part 22. The hook-shaped part 21 is movably connected to the frame 32 of the corresponding photovoltaic module 3.

[0059] Along the second direction X, the hook-shaped portion 21 can be connected to both ends of the connecting portion 22. The two hook-shaped portions 21 are symmetrically arranged and are respectively connected to the frame 32 of the corresponding photovoltaic module 3. The hook-shaped portion 21 and the connecting portion 22 can be integrally formed. The fastener 2 can have an integral structure, which facilitates the processing and forming of the fastener and helps to improve the stability and reliability of the connection between the fastener 2 and the photovoltaic module 3.

[0060] Combination Figure 1 As shown, in some embodiments, there is a gap between the connecting portion 22 and the clamp 1 along the first direction Z. The connecting portion 22 may have a corresponding mounting hole, and the connecting portion 22 protrudes away from the clamp 1. The fixing member 2 can be connected to the fastener 5 through the mounting hole. When the fastener 5 is tightened, since there is a certain gap between the connecting portion 22 and the clamp 1, a certain space is provided for the elastic deformation of the connecting portion 22, so that the connecting portion 22 can achieve a stable connection with the clamp 1 under the action of the fastener 5, that is, the stability of the connection between the fixing member 2 and the clamp 1 is improved, which is beneficial to improving the stability of the entire photovoltaic component.

[0061] In some embodiments, the fastener 2, the pressure block 4, and the clamp 1 can all be made of metal materials such as aluminum.

[0062] like Figure 3As shown, in some embodiments, the hook-shaped part 21 is connected to both ends of the connecting part 22. Along the first direction Z, there is a certain height difference between the hook-shaped part 21 and the connecting part 22, and the connecting part 22 is located above the hook-shaped part 21, so that the hook-shaped part 21 and the connecting part 22 can be connected to form an approximately "S" shaped structure, which is beneficial to improving the structural strength of the fastener 2 itself, and further beneficial to improving the stability of the connection between the fastener 2 and the photovoltaic module 3 and the stability of the connection between the fastener 2 and the clamp 1.

[0063] like Figure 1 and Figure 3 As shown, in one possible embodiment, the connecting part 22 has a first limiting protrusion 23 and a second limiting protrusion 24 spaced apart, with a limiting space between the first limiting protrusion 23 and the second limiting protrusion 24, and a portion of the structure of the clamp 1 is located within the limiting space, with the first limiting protrusion 23 and the second limiting protrusion 24 respectively abutting against the clamp 1.

[0064] The first limiting protrusion 23 and the second limiting protrusion 24 can be arranged at intervals along the second direction X, and the first limiting protrusion 23 and the second limiting protrusion 24 can extend along the first direction Z toward the clamp 1. The end of the clamp 1 can be located within the limiting space. The first limiting protrusion 23 and the second limiting protrusion 24 are located on both sides of the clamp 1 and abut against the clamp 1, thereby limiting the relative position of the fixing member 2 and the clamp 1, reducing the possibility of the fixing member 2 shifting and sliding on the clamp 1, and thus improving the stability of the connection between the fixing member 2 and the clamp 1. At the same time, the first limiting protrusion 23 and the second limiting protrusion 24 also play a pre-fixing role in the installation process of the fixing member 2. That is to say, the fixing member 2 can be pre-fixed to the clamp 1 by the first limiting protrusion 23 and the second limiting protrusion 24, and then the fixing member 2 and the clamp 1 can be fixed by the fastener 5. The first limiting protrusion 23 and the second limiting protrusion 24 realize the mutual positioning between the fixing member 2 and the clamp 1, so as to facilitate the installation of the fastener 5.

[0065] like Figure 4 and Figure 5 As shown, in one possible embodiment, the fastener 2 includes a first sub-fastener 25 and a second sub-fastener 26 stacked along the first direction Z. The first sub-fastener 25 and the second sub-fastener 26 are detachably connected. Hook-shaped portions 21 are located at the end of the first sub-fastener 25 away from the second sub-fastener 26 and the end of the second sub-fastener 26 away from the first sub-fastener 25, respectively. The hook-shaped portions 21 are movably connected to the frame 32 of the corresponding photovoltaic module 3.

[0066] The first sub-fixing member 25 can be stacked on the side of the second fixing member 2 facing away from the clamp 1. The first sub-fixing member 25 and the second sub-fixing member 26 are respectively provided with mounting holes for connection with the fastener 5, so that the first sub-fixing member 25 and the second sub-fixing member 26 are connected together by the fastener 5. Both the first sub-fixing member 25 and the second sub-fixing member 26 have the hook-shaped portion 21 described above, and the hook-shaped portion 21 of the first fixing member 2 and the hook-shaped portion 21 of the second sub-fixing member 26 are symmetrically arranged.

[0067] In some embodiments, the first sub-fixing member 25 may have a first positioning protrusion 251 and a first positioning recess 252, and the second sub-fixing member 26 may have a second positioning protrusion 261 and a second positioning recess 262. The first positioning protrusion 251 cooperates with the second positioning recess 262, and the second positioning protrusion 261 cooperates with the first positioning recess 252, so as to realize the mutual positioning of the first sub-fixing member 25 and the second sub-fixing member 26, and reduce the possibility of relative sliding between the first sub-fixing member 25 and the second sub-fixing member 26, thereby improving the stability of the fixing member 2 on the clamp 1.

[0068] The fixing member 2 can have a split structure. In the second direction X, one of two adjacent photovoltaic modules 3 can be movably connected to the hook-shaped part 21 of the first sub-fixing member 25, and the other can be movably connected to the hook-shaped part 21 of the second sub-fixing member 26. When a photovoltaic module 3 needs to be repaired or replaced, it is only necessary to remove the photovoltaic module 3 and the sub-fixing member 2 connected to the photovoltaic module 3 from the clamp 1. Other photovoltaic modules 3 adjacent to the photovoltaic module 3 will not be affected. At the same time, when the first sub-fixing member 25 or the second sub-fixing member 26 is damaged, it is only necessary to repair or replace the corresponding sub-fixing member 2. It is not necessary to disassemble the entire fixing member 2. This design facilitates the maintenance of photovoltaic components and extends the service life of photovoltaic components.

[0069] like Figure 4 and Figure 5 As shown, in some embodiments, along the first direction Z, the pressure block 4 is stacked on the side of the first sub-fixing member 25 facing away from the second sub-fixing member 26, and the pressure block 4 abuts against both the first sub-fixing member 25 and the second sub-fixing member 26. Along the second direction X, one end of the pressure block 4 extends toward the hook-shaped portion 21 of the first sub-fixing member 25, and the other end of the pressure block 4 extends toward the hook-shaped portion 21 of the second sub-fixing member 26. The function of the pressure block 4 has been described in detail above and will not be repeated here.

[0070] The pressure block 4 has a platform portion 41, the surface of which is flat. Along the first direction Z, the surface of the platform portion 41 abuts against the nut 52 to increase the contact area between the pressure block 4 and the nut 52, so that the fastener 5 can provide a stable and reliable fastening force, thereby achieving a solid connection between the pressure block 4, the fixing member 2 and the clamp 1, which in turn helps to improve the stability of the connection between the photovoltaic module 3 and the clamp 1.

[0071] In some embodiments, the dimension of the fastener 2 in the third direction Y, i.e., the width of the fastener 2, can be from 50mm to 120mm. For example, the width of the fastener 2 can be 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, 90mm, 95mm, 100mm, 105mm, 110mm, 115mm, or 120mm, or other values ​​within the above range. If the width of the fastener 2 is too small, for example, less than 50mm, the structural strength of the fastener 2 itself is low, making it difficult to achieve a stable and reliable connection with the photovoltaic module 3. This causes the photovoltaic module 3 to easily detach from the fastener 2 under external force, thereby reducing the overall reliability of the photovoltaic component. If the width of the fastener 2 is too large, for example, greater than 120mm, the size and weight of the fastener 2 become too large, making it difficult to meet the installation requirements of the photovoltaic component. Therefore, the width of the fastener 2 is designed to be between 50mm and 120mm, so as to meet the installation requirements of the photovoltaic components while giving the fastener 2 high structural strength, thereby improving the stability and reliability of the connection between the fastener 2 and the clamp 1 and between the fastener 2 and the photovoltaic module 3.

[0072] like Figure 4 and Figure 5 As shown, in one possible embodiment, the first sub-fixing member 25 has a first limiting protrusion 23, the second sub-fixing member 26 has a second limiting protrusion 24, there is a limiting space between the first limiting protrusion 23 and the second limiting protrusion 24, a part of the structure of the clamp 1 is located in the limiting space, and the first limiting protrusion 23 and the second limiting protrusion 24 respectively abut against the clamp 1.

[0073] The first limiting protrusion 23 and the second limiting protrusion 24 can be arranged at intervals along the second direction X. The first limiting protrusion 23 and the second limiting protrusion 24 can extend along the first direction Z toward the clamp 1. The end of the clamp 1 can be located within the limiting space. The first limiting protrusion 23 and the second limiting protrusion 24 are respectively on both sides of the clamp 1 and abut against the clamp 1. The function of setting the first limiting protrusion 23 and the second limiting protrusion 24 has been described in detail above and will not be repeated here.

[0074] like Figure 4 and Figure 5As shown, the photovoltaic component may include multiple corrugated steel sheets 6, which can be installed on the roof of a building, such as a factory or warehouse. Each corrugated steel sheet 6 has a male rib and a female rib at both ends. The male rib of one adjacent corrugated steel sheet 6 and the female rib of the other are connected to form a locking structure 61. The locking structure 61 extends along the second direction X, and the clamp 1 is held in place on the locking structure 61, thereby installing the photovoltaic module 3 on the corrugated steel sheet 6. As mentioned above, along the second direction X, a fixing member 2 can be connected between two adjacent photovoltaic modules 3, and these two adjacent photovoltaic modules 3 are connected to the clamp 1 through the fixing member 2. That is, the extension direction of the locking structure 61 can be parallel to the arrangement direction of the two photovoltaic modules 3 connected to the same clamp 1.

[0075] like Figure 6 As shown, in some embodiments, the fastener 2 may include a first sub-fastener 25 and a second sub-fastener 26. The first sub-fastener 25 and the second sub-fastener 26 are respectively located at both ends of the clamp 1 along the third direction Y. The first sub-fastener 25 and the second sub-fastener 26 respectively have the hook-shaped portion 21 described above. The hook-shaped portion 21 is movably connected to the frame 32 of the corresponding photovoltaic module 3.

[0076] The first sub-fixing member 25 and the second sub-fixing member 26 are respectively connected to the clamp 1 by their respective fasteners 5, and along the first direction Z, the first sub-fixing member 25 and the second sub-fixing member 26 are respectively provided with their respective pressure blocks 4 on the side away from the clamp 1.

[0077] The first sub-fixing member 25 and the second sub-fixing member 26 can be installed and removed using the corresponding fasteners 5. When repairing or replacing a photovoltaic module 3, simply tighten the fastener 5 corresponding to that photovoltaic module 3, reducing the possibility of mutual interference during the disassembly process of two adjacent photovoltaic modules 3, thereby facilitating the maintenance and repair of photovoltaic components and extending their service life.

[0078] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
