[0030] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0031] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0033] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0034] like Figure 1 As shown, an embodiment of the present application 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 a 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, and 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 toward the outside of the clamp 1 along the second direction X. 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, 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. The photovoltaic module 3 can convert solar energy into electrical energy, wherein, along the first direction Z, the laminate 31 has a light-receiving surface 31b and a backlight surface 31a, the light-receiving surface 31b is the surface of the laminate 31 that receives sunlight, and the backlight surface 31a is the surface of the laminate 31 that faces away from sunlight. The frame 32 is fixed on the backlight surface 31a, and the frame 32 can be set at the edge of the backlight surface 31a. The frame 32 can improve the structural strength of the photovoltaic module 3 and reduce the possibility of damage to the photovoltaic module 3 due to external forces during transportation, installation and use, so as to extend the life of the photovoltaic module 3 and improve the reliability of the photovoltaic module 3. At the same time, the frame 32 is arranged on the backlight surface 31a of the laminate 31, which reduces the possibility of the frame 32 blocking the light-receiving surface 31b of the laminate 31, that is, reduces the shading area, which is conducive to improving the efficiency of the photovoltaic module 3.

[0036] During the use of the photovoltaic component, the photovoltaic component 3 will be deformed under the action of external force (such as wind). For example, under the action of external force, the middle area of ​​the photovoltaic component 3 will bulge in the direction of the external force relative to the edge area. At this time, the frame 32 set at the edge of the photovoltaic component 3 will have a tendency to rotate relative to the fixing member 2. If the frame 32 is fixedly connected to the fixing member 2, that is, the frame 32 cannot move, then the edge area of ​​the photovoltaic component 3 is prone to stress concentration, which will cause the photovoltaic component 3 to break and be damaged, affecting the normal use of the entire photovoltaic component. Based on this, the embodiment of the present 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 component 3 is subjected to external force, thereby reducing the possibility of stress concentration and breakage of the photovoltaic component 3 at the connection position between the frame 32 and the fixing member 2 when the photovoltaic component 3 is subjected to external force, thereby improving the reliability of the installation of the photovoltaic component 3 and extending the service life of the photovoltaic component 3. At the same time, the fixing member 2 also plays a limiting role on the frame 32. Specifically, the fixing member 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 and the fixing member 2 being disconnected, and improve the stability and reliability of the connection between the frame 32 and the fixing member 2. Since the position of the photovoltaic component 3 in the first direction Z is limited, the possibility of the photovoltaic component 3 shaking significantly in the first direction Z is reduced, thereby improving the stability of the installation of the photovoltaic component 3, and the overall reliability of the photovoltaic component is improved.

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

[0038] For PERC cells, along the thickness direction, PERC cells include front surface metal silver electrode, front surface silicon nitride passivation layer, phosphorus layer emitter, P-type base silicon layer, local aluminum back field, metal aluminum back electrode, back passivation layer (Al2O3 / SiNx). PERC cells use a passivation film to passivate the back, replacing the full aluminum back field, enhancing the internal back reflection of light in the silicon base, reducing the recombination rate on the back, and increasing the efficiency of the cell by 0.5%-1%.

[0039] For TOPCon cells, along the thickness direction, TOPCon cells include metal silver electrodes, front surface silicon nitride passivation layers, boron-doped emitters, N-type base silicon layers, diffused doping layers, ultra-thin silicon oxide, doped polysilicon, silicon nitride, and metal silver electrodes. The back of the cell is composed of a layer of ultra-thin silicon oxide (1nm to 2nm) and a layer of phosphorus-doped microcrystalline amorphous mixed Si film, which together form a passivation contact structure. This structure can block the recombination of minority carrier holes and increase the open circuit voltage and short circuit current of the cell. The ultra-thin oxide layer allows majority electrons to tunnel into the polysilicon layer while blocking the recombination of minority carrier holes. The good passivation effect of ultra-thin silicon oxide and heavily doped silicon film causes the energy band on the silicon wafer surface to bend, thereby forming a field passivation effect, greatly increasing the probability of electron tunneling, reducing contact resistance, and increasing the open circuit voltage and short circuit current of the cell, thereby improving the cell conversion efficiency.

[0040] For HJT cells, along the thickness direction, the HJT cells include a front low-temperature silver electrode, a front conductive film, an N-type amorphous silicon film, an intrinsic amorphous silicon film, an N-type base 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 IBC cells, along the thickness direction, IBC cells include silicon nitride anti-layer, N+ front surface field, N-type base silicon layer, P+ emitter, N+ back field, aluminum oxide passivation layer, silicon nitride anti-reflection layer, and metal silver electrode. IBC cells use ion implantation technology to obtain P and N regions with good uniformity and precisely controllable junction depth. There is no grid line blocking on the front of the cell, which can eliminate the shading current loss of the metal electrode and achieve the maximum utilization of incident photons. The short-circuit current can be increased by about 7% compared with conventional solar cells; due to the back contact structure, there is no need to consider the grid line blocking problem, and the grid line ratio can be appropriately widened, thereby reducing the series resistance and having a high fill factor; the surface passivation and surface light trapping structure can be optimized to obtain a lower front surface recombination rate and surface reflection.

[0042] For perovskite cells, along the thickness direction, the perovskite cell includes substrate material, conductive film, electron transport layer (titanium dioxide), perovskite absorption layer (hole transport layer), and metal cathode. Perovskite materials have 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 electrode with low loss, so they can generate higher photoelectric voltage and current, making perovskite show higher photoelectric conversion efficiency.

[0043] like Figure 2 As shown, in a possible embodiment, the frame 32 includes a first main body portion 321 and a second main body portion 322 that are connected to each other, a cavity 323 is provided between the first main body portion 321 and the second main body portion 322, and the fixing member 2 includes a hook-shaped portion 21, the hook-shaped portion 21 is located in the cavity 323, and the hook-shaped portion 21 is movably connected to the first main 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 a structure that is approximately in the shape of a "C". The cavity 323 has a first opening 3231, and the direction of the first opening 3231 is along the second direction X toward the side away from the clamp 1. The shape of the hook-shaped portion 21 is also approximately in the shape of a "C". The hook-shaped portion 21 extends into the cavity 323 through the above-mentioned 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 together, 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 frame 32, that is, limit the position of the photovoltaic component 3 in the first direction Z.

[0045] As mentioned above, the photovoltaic module 3 will deform under the action of external force (such as wind), so that the frame 32 will tend to rotate relative to the fixing member 2. In the embodiment of the present application, the fixing member 2 is movably connected to the frame 32 through the hook-shaped portion 21. Since the shape of the hook-shaped portion 21 is similar to a "C" shape, it is convenient for the frame 32 to rotate relative to the fixing member 2, that is, it is conducive to the movable connection between the fixing member 2 and the frame 32, and reduces 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 when the photovoltaic module 3 is subjected to external force. At the same time, the hook-shaped portion 21 has a limiting effect on the frame 32 to limit the position of the photovoltaic module 3 in the first direction Z, reduce the possibility of the photovoltaic module 3 shaking significantly in the first direction Z, improve the stability of the installation of the photovoltaic module 3, and thus improve the overall reliability of the photovoltaic component.

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

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

[0048] The hook-shaped portion 21 provides a space for the frame 32 to rotate, thereby realizing the rotational connection between the hook-shaped portion 21 and the frame 32. Therefore, when the photovoltaic module 3 is deformed by an 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, thereby 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 portion 21 limits the frame 32, reduces the possibility of the frame 32 being disconnected from the fixing member 2, and reduces the possibility of the photovoltaic module 3 shaking significantly in the first direction Z, thereby improving the stability of the installation of the photovoltaic module 3.

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

[0050] like Figure 2 As shown, in a possible implementation, the second body portion 322 has a protruding portion 3221 protruding into the cavity 323 , and the protruding portion 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 may be a gap between the first end portion 3211 and the inner wall of the accommodating space 211 along the second direction X, that is, the first end portion 3211 does not abut against the inner wall of the accommodating space 211 along the second direction X. During the installation of the frame 32 and the fixing member 2, when the protrusion 3221 abuts against the hook-shaped portion 21, the frame 32 can no longer continue to move toward the side close to the hook-shaped portion 21 along the second direction X, so that the first end portion 3211 can maintain a certain distance from the inner wall of the accommodating space 211, thereby providing a space for the first end portion 3211 to rotate, so as to realize the rotation connection between the frame 32 and the hook-shaped portion 21. On the other hand, under the limiting effect of the protrusion 3221, the possibility of sliding and deflecting the frame 32 in the second direction X is reduced, so as to improve the stability and reliability of the installation of the photovoltaic module 3.

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

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

[0054] like Figure 1 and Figure 2 As shown, in a possible embodiment, the photovoltaic component also includes a pressing block 4, which is stacked on a side of the fixing member 2 away from the clamp 1 along the first direction Z. The pressing block 4, the fixing member 2 and the clamp 1 are fixedly connected by fasteners 5. The end of the pressing block 4 extends toward the direction close to 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 pressing block 4 abuts against the outer surface of the frame 32, the pressing block 4 limits the frame 32, preventing the frame 32 from moving along the second direction X toward the side close to the clamp 1, thereby reducing the possibility of the frame 32 being disconnected from the hook-shaped portion 21, so as to improve the stability and reliability of the installation of the photovoltaic module 3. As mentioned above, the second body portion 322 can have a protrusion 3221, and the protrusion 3221 and the pressing block 4 can limit the position of the frame 32 on the inner and outer sides of the frame 32, respectively, so as to further improve the stability of the connection between the frame 32 and the fixing member 2. The above-mentioned fastener 5 can include a bolt 51 and a nut 52, and the bolt 51 cooperates with the nut 52 to fix the pressing block 4, the fixing member 2 and the clamp 1 together.

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

[0057] like Figure 1 and Figure 3As shown, in a possible embodiment, the thickness of the fixing member 2 gradually decreases in the direction away from the clamp 1. Specifically, the fixing member 2 may include a connecting portion 22 and the above-mentioned hook-shaped portion 21, and 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 fixing member 2 and the clamp 1 are improved, which is conducive to achieving 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, which can be regarded as a cantilever structure. Therefore, by appropriately reducing the thickness of the hook-shaped portion 21, the overall structural strength of the fixing member 2 can be improved, the possibility of fracture and damage of the fixing member 2 can be reduced, and the reliability of the connection between the photovoltaic module 3 and the clamp 1 can be further improved.

[0058] like Figure 3 As shown, in a possible implementation, the fixing member 2 includes a connecting portion 22 connected to the clamp 1 , a hook-shaped portion 21 connected to both ends of the connecting portion 22 , and the hook-shaped portion 21 is movably connected to the frame 32 of the corresponding photovoltaic component 3 .

[0059] Along the second direction X, the hook-shaped portion 21 can be connected to both ends of the connecting portion 22, and the two hook-shaped portions 21 are symmetrically arranged and respectively connected to the corresponding frames 32 of the photovoltaic module 3, wherein the hook-shaped portion 21 and the connecting portion 22 can be integrally formed. The fixing member 2 can have an integral structure, so as to facilitate the processing and forming of the fixing member, and at the same time, it is beneficial to improve the stability and reliability of the connection between the fixing member 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 be provided with a corresponding mounting hole, and the connecting portion 22 protrudes in a direction away from the clamp 1. The fixing member 2 may be connected to the above-mentioned fastener 5 through the mounting hole. When tightening the fastener 5, 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 be stably connected to 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 conducive to improving the stability of the entire photovoltaic component.

[0061] In some embodiments, the fixing member 2 , the pressing block 4 and the clamp 1 may all be made of metal materials such as aluminum.

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

[0063] like Figure 1 and Figure 3 As shown, in a possible embodiment, the connecting portion 22 has a first limiting protrusion 23 and a second limiting protrusion 24 that are spaced apart, and there is a limiting space between the first limiting protrusion 23 and the second limiting protrusion 24. 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 are respectively abutted 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 in the direction close to the clamp 1 along the first direction Z. The end of the clamp 1 can be located in the limiting space, and the first limiting protrusion 23 and the second limiting protrusion 24 are respectively 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 offsetting 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 role of pre-fixing during the installation process of the fixing member 2, that is, the fixing member 2 can be pre-fixed with the clamp 1 through the first limiting protrusion 23 and the second limiting protrusion 24, and then the fixing member 2 and the clamp 1 are 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 a possible embodiment, the fixing member 2 includes a first sub-fixing member 25 and a second sub-fixing member 26 stacked along a first direction Z, the first sub-fixing member 25 and the second sub-fixing member 26 are detachably connected, and the hook-shaped portion 21 is respectively located at one end of the first sub-fixing member 25 away from the second sub-fixing member 26 and one end of the second sub-fixing member 26 away from the first sub-fixing member 25, and the hook-shaped portion 21 is movably connected to the frame 32 of the corresponding photovoltaic component 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, and the first sub-fixing member 25 and the second sub-fixing member 26 are respectively provided with mounting holes connected to the fastener 5, so that the first sub-fixing member 25 and the second sub-fixing member 26 are connected together through the fastener 5. The first sub-fixing member 25 and the second sub-fixing member 26 both have the above-mentioned hook-shaped portion 21, 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 to achieve 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 set on the clamp 1.

[0068] The fixing member 2 can have a split structure. In the second direction X, one of the two adjacent photovoltaic components 3 can be movably connected to the hook-shaped portion 21 of the first sub-fixing member 25, and the other can be movably connected to the hook-shaped portion 21 of the second sub-fixing member 26. When a photovoltaic component 3 needs to be repaired or replaced, it is only necessary to remove the photovoltaic component 3 and the sub-fixing member 2 connected to the photovoltaic component 3 from the clamp 1, and other photovoltaic components 3 adjacent to the photovoltaic component 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 and replace the corresponding sub-fixing member 2 without disassembling the entire fixing member 2. This design facilitates the repair and maintenance of photovoltaic components to extend the service life of photovoltaic components.

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

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

[0071] In some embodiments, the size of the fixing member 2 in the third direction Y, that is, the width of the fixing member 2 can be 50mm to 120mm. For example, the width of the fixing member 2 can be 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, 90mm, 95mm, 100mm, 105mm, 110mm, 115mm or 120mm. Of course, it can also be other values ​​within the above range. If the width of the fixing member 2 is too small, for example, less than 50mm, the structural strength of the fixing member 2 itself is low, and it is difficult to achieve a stable and reliable connection with the photovoltaic component 3, resulting in the photovoltaic component 3 being easily separated from the fixing member 2 under the action of external force, thereby reducing the overall reliability of the photovoltaic component. If the width of the fixing member 2 is too large, for example, greater than 120mm, the size of the fixing member 2 is too large, and the weight is too large, which makes it difficult to meet the installation requirements of the photovoltaic component. Therefore, the width of the fixing member 2 is designed to be 50 mm to 120 mm, so that the fixing member 2 has a higher structural strength while meeting the installation requirements of the photovoltaic component, thereby improving the stability and reliability of the connection between the fixing member 2 and the clamp 1 and between the fixing member 2 and the photovoltaic component 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, 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 are respectively abutted against the clamp 1.

[0073] The first limiting protrusion 23 and the second limiting protrusion 24 may be arranged at intervals along the second direction X. The first limiting protrusion 23 and the second limiting protrusion 24 may extend along the first direction Z toward the direction close to the clamp 1, and the end of the clamp 1 may be located in the limiting space, and 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 functions of setting the first limiting protrusion 23 and the second limiting protrusion 24 have been described in detail above and will not be repeated here.

[0074] like Figure 4 and Figure 5As shown, the photovoltaic component may include a plurality of color steel tiles 6, and the color steel tiles 6 may be installed on the roof of a building, and the building may be a factory building of a production enterprise, a warehouse, etc. Male ribs and female ribs are respectively provided at both ends of the color steel tile 6, and the male ribs of one of the two adjacent color steel tiles 6 and the female ribs of the other are connected to form a locking structure 61, and the locking structure 61 extends along the second direction X, and the clamp 1 is clamped on the locking structure 61, so that the photovoltaic module 3 is installed on the color steel tile 6. As mentioned above, along the second direction X, a fixing member 2 may be connected between two adjacent photovoltaic modules 3, and the 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 may 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 fixing member 2 may include a first sub-fixing member 25 and a second sub-fixing member 26, and the first sub-fixing member 25 and the second sub-fixing member 26 are respectively located at two ends of the clamp 1 along the third direction Y, and the first sub-fixing member 25 and the second sub-fixing member 26 respectively have the above-mentioned hook-shaped portion 21, and the hook-shaped portion 21 is movably connected to the frame 32 of the corresponding photovoltaic component 3.

[0076] The first sub-fixing member 25 and the second sub-fixing member 26 are connected to the clamp 1 through respective fasteners 5 , and along the first direction Z, respective pressing blocks 4 are provided on the sides of the first sub-fixing member 25 and the second sub-fixing member 26 facing away from the clamp 1 .

[0077] The first sub-fixing member 25 and the second sub-fixing member 26 can be installed and removed by corresponding fasteners 5. When a photovoltaic module 3 is to be repaired or replaced, it is only necessary to twist the fastener 5 corresponding to the photovoltaic module 3, thereby reducing the possibility of mutual interference in the disassembly process of two adjacent photovoltaic modules 3, thereby facilitating the repair and maintenance of the photovoltaic components and extending the service life of the photovoltaic components.

[0078] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
