DETAILED DESCRIPTION

[0019] 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.

[0020] 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.

[0021] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit 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.

[0022] 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.

[0023] like Figure 1 As shown, an embodiment of the present application provides a photovoltaic component, including a clamp 1, a fixing member 2 and a pressing assembly, wherein the fixing member 2 is connected to one side of the clamp 1 along a first direction Z, the fixing member 2 includes a first end 21 and a second end 22 along a second direction X, the first end 21 and the second end 22 are connected to corresponding photovoltaic components 3, and the pressing assembly is connected to a side of the fixing member 2 away from the clamp 1 along the first direction Z, wherein the pressing assembly includes a first pressing block 4 and a second pressing block 5 arranged along a third direction Y, the first pressing block 4 extends toward the first end 21, and the first pressing block 4 is used to limit the position of the photovoltaic component 3 connected to the first end 21 in the second direction X, and the second pressing block 5 extends toward the second end 22, and the second pressing block 5 is used to limit the position of the photovoltaic component 3 connected to the second end 22 in the second direction X.

[0024] The photovoltaic module 3 is used to convert solar energy into electrical energy. The fixing member 2 is fixedly connected to one side of the clamp 1 along the first direction Z. The first end 21 and the second end 22 of the fixing member 2 can both extend toward the outside of the clamp 1 along the second direction X and be connected to the corresponding photovoltaic module 3. That is, in the second direction X, a fixing member 2 can 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. The pressing assembly can abut against the fixing member 2 along the first direction Z. The first pressing block 4 can extend toward the first end 21 along the second direction X. The end of the first pressing block 4 can abut against the photovoltaic module 3 connected to the first end 21, thereby limiting the position of the photovoltaic module 3 in the second direction X. The second pressing block 5 can extend toward the second end 22 along the second direction X. The end of the second pressing block 5 can abut against the photovoltaic module 3 connected to the second end 22, thereby limiting the position of the photovoltaic module 3 in the second direction X. Wherein, the first direction Z is orthogonal to the second direction X.

[0025] The pressing assembly presses the fixing member 2 and the clamp 1, reducing the possibility of the fixing member 2 shaking on the clamp 1 or falling off the clamp 1, thereby improving the stability of the connection between the fixing member 2 and the clamp 1. The photovoltaic module 3 is connected to the clamp 1 through the fixing member 2, and under the action of the pressing assembly, the photovoltaic module 3 is stably and reliably connected to the clamp 1. Among them, the first pressing block 4 and the second pressing block 5 respectively limit the corresponding photovoltaic module 3, reducing the possibility of the photovoltaic module 3 sliding in the second direction X, thereby reducing the possibility of the photovoltaic module 3 being disconnected from the fixing member 2, improving the reliability of the connection between the photovoltaic module 3 and the fixing member 2, that is, improving the reliability of the installation of the photovoltaic module 3, so that the photovoltaic module 3 is more resistant to wind and trampling, etc., thereby improving the overall reliability of the photovoltaic component and extending the service life of the photovoltaic component. At the same time, since the two photovoltaic components 3 connected to the clamp 1 are limited by different pressure blocks respectively, the installation and disassembly of the photovoltaic components 3 are more convenient. For example, when a photovoltaic component 3 needs to be repaired or replaced, it is only necessary to remove the pressure block corresponding to the photovoltaic component 3 from the clamp 1 to release the limiting effect of the pressure block on the photovoltaic component 3, thereby facilitating the separation of the photovoltaic component 3 from the fixing part 2 and reducing the possibility of affecting other photovoltaic components 3.

[0026] like Figure 1 and Figure 2 As shown, in a possible embodiment, the photovoltaic component 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, and the first end 21 and the second end 22 are respectively connected to the frame 32 of the corresponding photovoltaic component 3.

[0027] Along the first direction Z, the laminate 31 has a light-receiving surface 31b and a backlight surface 31a, wherein 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 arranged at the edge of the backlight surface 31a. The provision of the frame 32 can improve the structural strength of the photovoltaic module 3, and reduce the possibility of damage to the photovoltaic module 3 caused by 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.

[0028] The first pressing block 4 and the second pressing block 5 can abut against the frame 32 of the corresponding photovoltaic assembly 3, thereby limiting the photovoltaic assembly 3. Figure 2 As shown, taking the first pressing block 4 as an example, the first pressing block 4 can abut against the outer side wall of the frame 32 along the second direction X, thereby limiting the position of the photovoltaic component 3 in the second direction X.

[0029] 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.

[0030] For PERC cells, along the thickness direction, PERC cells include the front surface metal silver electrode, the front surface silicon nitride passivation layer, the phosphorus layer emitter, the P-type base silicon layer, the local aluminum back field, the metal aluminum back electrode, and the 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%.

[0031] 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 an ultra-thin silicon oxide layer (1nm~2nm) and a 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, and reducing the contact resistance, which increases the open circuit voltage and short circuit current of the cell, thereby improving the cell conversion efficiency.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] like Figure 1 and Figure 2As shown, in some embodiments, the frame 32 includes a first body portion 321 and a second body portion 322 connected to each other, the first body portion 321 and the second body portion 322 can be arranged along the first direction Z, the first body portion 321 and the second body portion 322 can be connected to form a structure similar to a "C" shape, and a cavity 323 is provided between the first body portion 321 and the second body portion 322. The cavity 323 has a first opening 324, and the direction of the first opening 324 is toward the side away from the clamp 1 along the second direction X. The first end 21 and the second end 22 of the fixing member 2 have a hook-shaped portion 26, and the shape of the hook-shaped portion 26 is also similar to a "C" shape. The hook-shaped portion 26 extends into the cavity 323 through the above-mentioned first opening 324, and the hook-shaped portion 26 is movably connected to the first body portion 321. The frame 32 and the hook-shaped portion 26 can be interlocked together, and the frame 32 can move relative to the hook-shaped portion 26, that is, the photovoltaic component 3 and the fixing member 2 are movably connected.

[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, by movably connecting the fixing member 2 with the frame 32, 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.

[0037] The hook-shaped portion 26 provides a rotation space for the frame 32, thereby realizing the rotation connection between the hook-shaped portion 26 and the frame 32. At the same time, the hook-shaped portion 26 can abut against the first body portion 321 along the first direction Z, so that the hook-shaped portion 26 plays a limiting role on the frame 32, limiting the position of the photovoltaic component 3 in the first direction Z, thereby improving the stability of the installation of the photovoltaic component 3 and reducing the possibility of the photovoltaic component 3 falling off the clamp 1. 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, so that the overall reliability of the photovoltaic component is improved.

[0038] like Figure 3As shown, in a possible implementation manner, the first pressing block 4 , the fixing member 2 , and the clamp 1 are connected via a first bolt 61 , and the second pressing block 5 , the fixing member 2 , and the clamp 1 are connected via a second bolt 71 .

[0039] The first pressing block 4 and the second pressing block 5 are connected to the clamp 1 by different bolts respectively. Figure 1 As shown, specifically, during the installation of the photovoltaic component, the first end 21 of the fixing member 2 can be connected to the photovoltaic module 3 first, and then the first pressing block 4 can be pressed onto the fixing member 2, and then the first pressing block 4, the fixing member 2 and the clamp 1 can be fixed together by the first bolt 61. After that, the second end 22 of the fixing member 2 can be connected to the photovoltaic module 3, and then the second pressing block 5 can be pressed onto the fixing member 2, and then the second pressing block 5, the fixing member 2 and the clamp 1 can be fixed together by the second bolt 71. This design allows the first pressing block 4 and the second pressing block 5 to be installed and disassembled separately, thereby facilitating the separate installation and disassembly of the photovoltaic module 3, and then facilitating the maintenance and replacement of the photovoltaic module 3, thereby extending the service life of the photovoltaic component.

[0040] like Figure 3 and Figure 4 As shown, in a possible embodiment, the first pressing block 4 is provided with a first mounting hole 41, and the first pressing block 4 is connected to the first bolt 61 through the first mounting hole 41. The second pressing block 5 is provided with a second mounting hole 51, and the second pressing block 5 is connected to the second bolt 71 through the second mounting hole 51. The first mounting hole 41 and the second mounting hole 51 are both waist-shaped holes arranged along the second direction X.

[0041] After the first pressing block 4 is connected to the first bolt 61, since the first mounting hole 41 is a waist-shaped hole, before the first bolt 61 is fastened with the first nut 62, the first pressing block 4 can move relative to the first bolt 61 along the second direction X. Similarly, after the second pressing block 5 is connected to the second bolt 71, since the second mounting hole 51 is a waist-shaped hole, before the second bolt 71 is fastened with the second nut 72, the second pressing block 5 can move relative to the second bolt 71 along the second direction X.

[0042] Combination Figure 1As shown, when the photovoltaic component is installed, the clamp 1, the fixing member 2, the first pressing block 4 and the second pressing block 5 can be pre-fixed first. Specifically, the first pressing block 4 is pre-fixed with the fixing member 2 and the clamp 1 through the first bolt 61, and the second pressing block 5 is pre-fixed with the fixing member 2 and the clamp 1 through the second bolt 71. Since the first bolt 61 is not fastened with the first nut 62, and the second bolt 71 is not fastened with the second nut 72, the first pressing block 4 can move relative to the first bolt 61, and the second pressing block 5 can move relative to the second bolt 71, that is, at this time, the clamp 1, the fixing member 2, the first pressing block 4 and the second pressing block 5 are in a pre-fixed state. When the first end 21 of the fixing member 2 is connected to the photovoltaic component 3, the first pressing block 4 can be moved in a direction away from the first end 21, so as to leave space for the installation of the photovoltaic component 3, so as to facilitate the connection of the photovoltaic component 3 with the first end 21. After the photovoltaic module 3 is connected to the first end 21, the first pressing block 4 is moved to a preset position in a direction close to the first end 21, so that the first pressing block 4 can limit the photovoltaic module 3. At this time, the first nut 62 and the first bolt 61 are tightened to fix the first pressing block 4, the fixing member 2 and the clamp 1 together. The connection process between the second end 22 of the fixing member 2 and the photovoltaic module 3 is the same as the connection process between the first end 21 of the fixing member 2 and the photovoltaic module 3, which will not be repeated here.

[0043] When it is necessary to disassemble a photovoltaic module 3 on the clamp 1, the corresponding nut can be removed to make the pressing block corresponding to the photovoltaic module 3 movable, and then the pressing block is moved away from the photovoltaic module 3 to release the limiting effect of the pressing block on the photovoltaic module 3, thereby providing space for the disassembly of the photovoltaic module 3, so that the photovoltaic module 3 is separated from the clamp 1, so as to facilitate the maintenance and replacement of the photovoltaic module 3. Since there is no need to disassemble the pressing block from the clamp 1, the disassembly process of the photovoltaic module 3 is simplified and more convenient to operate.

[0044] It can be seen from the above that by designing the first mounting hole 41 and the second mounting hole 51 as waist-shaped holes, the first pressing block 4 and the second pressing block 5 can have a pre-fixed state, that is, the first pressing block 4 and the second pressing block 5 have a movable state, thereby facilitating the adjustment of the position of the first pressing block 4 and the second pressing block 5 on the fixing member 2, thereby facilitating the installation and disassembly of the photovoltaic module 3.

[0045] like Figures 4 to 6 As shown, in a possible embodiment, the first pressure block 4 includes a first protrusion 42, the first bolt 61 is connected to the first nut 62, and the first nut 62 can abut against the first protrusion 42 along the second direction X, and the second pressure block 5 includes a second protrusion 52, the second bolt 71 is connected to the second nut 72, and the second nut 72 can abut against the second protrusion 52 along the second direction X.

[0046] The first protrusion 42 may be formed by the end of the first pressing block 4 protruding in a direction away from the clamp 1, and the second protrusion 52 may be formed by the end of the second pressing block 5 protruding in a direction away from the clamp 1. The first protrusion 42 limits the first nut 62 to limit the relative position of the first nut 62 and the first pressing block 4, thereby improving the stability of the first pressing block 4. Similarly, the second protrusion 52 limits the second nut 72 to limit the relative position of the second nut 72 and the second pressing block 5, thereby improving the stability of the second pressing block 5.

[0047] like Figures 4 to 6 As shown, in a possible embodiment, the fixing member 2 includes a connecting portion 23, and the connecting portion 23 has a gap with the clamp 1 along the first direction Z. The first pressure block 4 includes a first abutting portion 43, and along the first direction Z, one end of the first abutting portion 43 abuts against the first nut 62, and the other end of the first abutting portion 43 abuts against the connecting portion 23. The second pressure block 5 includes a second abutting portion 53, and along the first direction Z, one end of the second abutting portion 53 abuts against the second nut 72, and the other end of the second abutting portion 53 abuts against the connecting portion 23.

[0048] Along the first direction Z, the connection part 23 protrudes in the direction away from the clamp 1, so that there is a certain distance between the connection part 23 and the clamp 1. The connection part 23 may be provided with a mounting hole corresponding to the first bolt 61 and a mounting hole corresponding to the second bolt 71. When tightening the nut, since there is a certain distance between the connection part 23 and the clamp 1, a certain space is provided for the elastic deformation of the connection part 23, so that the connection part 23 can be stably connected with the clamp 1 under the action of each bolt and nut, 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.

[0049] The first abutment portion 43 of the first pressure block 4 abuts against the first nut 62 and the connecting portion 23, thereby improving the stability and reliability of the connection between the first pressure block 4 and the fixing member 2. The second abutment portion 53 of the second pressure block 5 abuts against the second nut 72 and the connecting portion 23, thereby improving the stability and reliability of the connection between the second pressure block 5 and the fixing member 2, thereby facilitating improving the reliability of the installation of the photovoltaic module 3, and further improving the overall reliability of the photovoltaic module 3.

[0050] like Figures 4 to 6As shown, in some embodiments, the first pressing block 4 has a first platform portion 45, and the surface of the first platform portion 45 is a plane. Along the first direction Z, the surface of the first platform portion 45 abuts against the first nut 62 to increase the contact area between the first pressing block 4 and the first nut 62, so that the first nut 62 can provide a stable and reliable fastening force, thereby achieving a stable connection between the first pressing block 4, the fixing member 2 and the clamp 1. The second pressing block 5 has a second platform portion 55, and the surface of the second platform portion 55 is a plane. Along the first direction Z, the surface of the second platform portion 55 abuts against the second nut 72 to increase the contact area between the second pressing block 5 and the second nut 72, so that the second nut 72 can provide a stable and reliable fastening force, thereby achieving a stable connection between the second pressing block 5, the fixing member 2 and the clamp 1.

[0051] like Figure 3 and Figure 4 As shown, in a possible embodiment, the first pressing block 4 is provided with a first positioning portion 44, the second pressing block 5 is provided with a second positioning portion 54, and the fixing member 2 is provided with a first matching portion and a second matching portion (not shown in the figure), the first positioning portion 44 cooperates with the first matching portion, and the second positioning portion 54 cooperates with the second matching portion to limit the relative positions of the first pressing block 4, the second pressing block 5 and the fixing member 2.

[0052] Among them, the first positioning portion 44 can be matched with the first matching portion in a concave-convex manner, and the second positioning portion 54 can be matched with the second matching portion in a concave-convex manner, so as to limit the positions of the first pressing block 4 and the second pressing block 5 on the fixing member 2, and reduce the possibility of shaking and shifting of the first pressing block 4 and the second pressing block 5 on the fixing member 2, so as to improve the stability of the setting of the first pressing block 4 and the second pressing block 5. At the same time, it is also convenient to position the first pressing block 4, the second pressing block 5 and the fixing member 2, so as to facilitate the installation of the photovoltaic component.

[0053] like Figure 7 As shown, in some embodiments, the fixing member 2 may be an integrated structure. Specifically, the fixing member 2 may include a connecting portion 23 and a hook-shaped portion 26. Figure 1 and Figure 2 As shown, the connecting portion 23 is connected to the clamp 1, and along the second direction X, the hook-shaped portion 26 can be connected to both ends of the connecting portion 23, and the two hook-shaped portions 26 are symmetrically arranged, and the two hook-shaped portions 26 are movably connected to the frame 32 of the corresponding photovoltaic module 3. Among them, the hook-shaped portion 26 and the connecting portion 23 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 2, 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.

[0054] like Figure 8As shown, in a possible embodiment, the fixing member 2 includes a first sub-fixing member 24 and a second sub-fixing member 25 stacked along a first direction Z, the first sub-fixing member 24 and the second sub-fixing member 25 are detachably connected, the end of the first sub-fixing member 24 away from the second sub-fixing member 25 is a first end 21, the end of the second sub-fixing member 25 away from the first sub-fixing member 24 is a second end 22, and the first pressing block 4 and the second pressing block 5 are connected to the side of the first sub-fixing member 24 away from the second sub-fixing member 25.

[0055] The first sub-fixing member 24 may be stacked on a side of the second fixing member 2 facing away from the clamp 1 , and the first sub-fixing member 24 and the second sub-fixing member 25 may be connected together by a first bolt 61 and a second bolt 71 .

[0056] In the second direction X, one of two adjacent photovoltaic modules (not shown in the figure) can be connected to the first end 21 of the first sub-fixing member 24, and the other can be connected to the second end 22 of the second sub-fixing member 25. The first end 21 of the first sub-fixing member 24 can have a hook-shaped portion 26, and the second end 22 of the second sub-fixing member 25 can have a hook-shaped portion 26. The first sub-fixing member 24 and the second sub-fixing member 25 can be movably connected to the photovoltaic module 3 through their respective hook-shaped portions 26.

[0057] like Fig. 9 As shown, in some embodiments, the first sub-fixing member 24 may have a third positioning portion 241, and the second sub-fixing member 25 may have a fourth positioning portion 251. The third positioning portion 241 and the fourth positioning portion 251 are matched in a concave-convex manner to achieve the mutual positioning of the first sub-fixing member 24 and the second sub-fixing member 25, and reduce the possibility of relative sliding between the first sub-fixing member 24 and the second sub-fixing member 25, thereby improving the stability of the fixing member 2 set on the clamp 1.

[0058] The fixing member 2 can be a split structure, which is convenient for the installation and disassembly of the fixing member 2 and the photovoltaic module 3. For example, 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, and other photovoltaic modules 3 adjacent to the photovoltaic module 3 will not be affected. At the same time, when the first sub-fixing member 24 or the second sub-fixing member 25 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 maintenance of photovoltaic components to extend the service life of photovoltaic components.

[0059] like Fig.10As shown, in a possible embodiment, the fixing member 2 includes a first sub-fixing member 24 and a second sub-fixing member 25 arranged along a third direction Y, one end of the first sub-fixing member 24 is a first end 21, one end of the second sub-fixing member 25 is a second end 22, the first pressing block 4 is connected to the first sub-fixing member 24, and the second pressing block 5 is connected to the second sub-fixing member 25.

[0060] The first sub-fixing member 24 and the second sub-fixing member 25 are respectively arranged at the two ends of the clamp 1 along the third direction Y. In the second direction X, one of the two adjacent photovoltaic modules (not shown in the figure) can be connected to the first end 21 of the first sub-fixing member 24, and the other can be connected to the second end 22 of the second sub-fixing member 25. Among them, the first end 21 of the first sub-fixing member 24 can have a hook-shaped portion 26, and the second end 22 of the second sub-fixing member 25 can have a hook-shaped portion 26, and the first sub-fixing member 24 and the second sub-fixing member 25 can be movably connected to the photovoltaic module 3 through their respective hook-shaped portions 26. The first sub-fixing member 24, the first pressing block 4 and the clamp 1 can be connected through the first bolt 61, and the second sub-fixing member 25, the second pressing block 5 and the clamp 1 can be connected through the second bolt 71. The above design facilitates the installation and disassembly of the photovoltaic components 3. For example, when repairing or replacing a photovoltaic component 3, it is sufficient to loosen the bolts corresponding to the photovoltaic component 3, thereby reducing the possibility of mutual interference during the disassembly process of two adjacent photovoltaic components 3, thereby facilitating the repair and replacement of photovoltaic components to extend the service life of the photovoltaic components.

[0061] like Fig.11 As shown, in a possible embodiment, the photovoltaic component includes a color steel tile 8, and male ribs and female ribs are respectively provided at both ends of the color steel tile 8. The male rib of one of the two adjacent color steel tiles 8 and the female rib of the other are connected to form a locking structure 81. The locking structure 81 extends along the second direction X, and the clamp 1 is connected to the locking structure 81.

[0062] The color steel tile 8 can be installed on the roof of a building, which can be a factory building, warehouse, etc. The male rib and the female rib are respectively located at the two ends of the color steel tile 8 along the third direction Y. The third direction Y is orthogonal to the first direction Z and the second direction X mentioned above. The third direction Y can be regarded as the width direction of the color steel tile 8. The locking structure 81 formed by connecting two adjacent color steel tiles 8 extends along the second direction X. The second direction X can be regarded as the length direction of the color steel tile 8. Fig.10As shown, as mentioned above, the fixing member 2 includes a first end 21 and a second end 22 along the second direction X, and the first end 21 and the second end 22 are connected to corresponding photovoltaic modules (not shown in the figure), that is, the extension direction of the locking structure 81 can be parallel to the arrangement direction of the two photovoltaic modules connected to the same clamp 1. The above design makes the installation of the photovoltaic module no longer restricted by the width of the color steel tile 8, so that the photovoltaic module can be adapted to the color steel tile 8 of different widths, thereby improving the flexibility of the installation of the photovoltaic module.

[0063] The first pressing block and the second pressing block mentioned above are split structures. In some other embodiments, the pressing block on the fixing member can be an integrated structure. Fig.12 As shown, the photovoltaic component may include a third pressing block 9, which is stacked on the side of the first sub-fixing member 24 away from the second sub-fixing member 25, and the third pressing block 9 is respectively abutted against the first sub-fixing member 24 and the second sub-fixing member 25. Along the second direction X, one end of the third pressing block 9 extends toward the outer end of the first sub-fixing member 24, and can abut against the photovoltaic component 3 connected to the first sub-fixing member 24, and the other end of the third pressing block 9 extends toward the outer end of the second sub-fixing member 25, and can abut against the photovoltaic component 3 connected to the second sub-fixing member 25. The third pressing block 9 has a limiting effect on the photovoltaic component 3, so as to improve the stability and reliability of the installation of the photovoltaic component 3.

[0064] The thickness of the third pressing block 9 may gradually decrease in the direction away from the clamp 1 , so as to improve the structural strength of the third pressing block 9 , thereby improving the reliability of the third pressing block 9 and achieving a stable connection between the third pressing block 9 and the fixing member 2 .

[0065] like Fig.13 As shown, in some embodiments, the fixing member 2 connected to the third pressing block 9 may be an integrated structure. The fixing member 2 of the integrated structure has been described above and will not be described again here.

[0066] The above description is only the preferred embodiment of the present application and is 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.
