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.

[0097] The present application embodiment provides a photovoltaic component, such as Figure 1 , Figure 2 and Figure 3 As shown, the photovoltaic component includes a clamp 10, a color steel tile 20, a photovoltaic module 30 and a fixing part 40. A plurality of color steel tiles 20 are installed on the ground or the main body of the building through a bracket 70, and two adjacent color steel tiles 20 along the first direction X overlap each other and are bent to form a lock edge 201. The clamp 10 includes a clamping portion 101, and the clamping portion 101 is used to clamp the lock edge 201 along the first direction X so that the clamp 10 is fixedly connected to the color steel tile 20. The two ends of the fixing part 40 along the second direction Y are respectively connected to the clamping portion 101 and the photovoltaic module 30 to install the photovoltaic module 30 on the color steel tile 20, so as to use solar energy to generate electricity to meet daily use needs. Among them, the main body of the building includes but is not limited to the roof and wall of buildings such as factories and warehouses of production enterprises. This embodiment is described by taking the main body of the building as the roof as an example.

[0098] It should be noted that the first direction X and the second direction Y are perpendicular to each other, the second direction Y is specifically the length direction of the locking edge 201, and the first direction X is specifically the direction perpendicular to the locking edge 201. In this embodiment, the length direction of the photovoltaic module 30 is parallel to the first direction X, and the width direction of the photovoltaic module 30 is parallel to the second direction Y.

[0099] In this embodiment, the width direction of the photovoltaic component 30 is parallel to the length direction (second direction Y) of the lock edge 201, and the fixing member 40 connects the clamp 10 and the photovoltaic component 30 along the second direction Y. There is no need to make the width of the photovoltaic component 30 consistent with the width of the color steel tile 20, so that the photovoltaic component 30 can be adapted to color steel tiles 20 of different widths. That is, this embodiment does not limit the version structure of the color steel tile 20 and has a high degree of flexibility.

[0100] The connection structure between the clamp 10 and the color steel tile 20 is first described in detail below:

[0101] like Figure 2 As shown, the clamp 10 includes a first clamping portion 1 and a second clamping portion 2 that are relatively distributed along a first direction X. The first clamping portion 1 and the second clamping portion 2 are used to clamp the locking edge 201 of the color steel tile 20 together so that the clamp 10 can be fixed to the color steel tile 20. Figure 4 and Figure 5As shown, the first clamping part 1 is provided with a first clamping arm 12, and the first clamping arm 12 includes a first body 121 and a second body 122; the second clamping part 2 is provided with a second clamping arm 22, and the second clamping arm 22 includes a third body 221 and a fourth body 222. The second body 122 and the fourth body 222 both extend along the height direction Z of the clamp 10, and along the first direction X, a clamping space 120 is formed between the second body 122 and the fourth body 222, and at least part of the locking edge 201 is accommodated in the clamping space 120, so that the second body 122 and the fourth body 222 can clamp the locking edge 201 together along the first direction X, so as to achieve a stable connection between the clamp 10 and the color steel tile 20. Among them, a side surface of the second body 122 facing the clamping space 120 and / or a side surface of the fourth body 222 facing the clamping space 120 can be provided with a corrugated structure 223. The corrugated structure 223 can increase the friction between the locking edge 201 and the clamp 10 , which is beneficial to improving the installation stability of the clamp 10 and reducing the risk of the clamp 10 moving relative to the locking edge 201 , thereby improving the connection reliability between the clamp 10 and the locking edge 201 .

[0102] In a specific embodiment, Figure 2 and Figure 4 As shown, along the height direction Z of the clamp 10, the end of the second body 122 away from the first body 121 is provided with a first extension section 123, and the first extension section 123 extends along the first direction X toward the direction close to the fourth body 222. On the one hand, by providing the first extension section 123, the distance between the bottom end of the second body 122 and the bottom end of the fourth body 222 can be reduced, which is conducive to improving the clamping of the clamp 10 on the locking edge 201; on the other hand, the first extension section 123 can overlap the surface of the color steel tile 20, which is conducive to improving the structural stability of the first clamping part 1 and reducing the risk of the first clamping part 1 being tilted, thereby facilitating the installation stability of the clamp 10.

[0103] Furthermore, a hook structure is provided at one end of the first extension section 123 facing the fourth body 222 , and the hook structure can press at least a portion of the locking edge 201 against the fourth body 222 , thereby improving the clamping effect of the clamp 10 on the locking edge 201 .

[0104] In a specific embodiment, Figure 2 and Figure 5 As shown, along the height direction Z of the clamp 10, the end of the fourth body 222 away from the third body 221 is provided with a second extension section 224, and the second extension section 224 extends in the first direction X in a direction away from the second body 122. The second extension section 224 can overlap the surface of the color steel tile 20, which is beneficial to improve the structural stability of the second clamping part 2 and reduce the risk of the second clamping part 2 tilting, thereby facilitating the installation stability of the clamp 10.

[0105] In a specific embodiment, Figure 4 and Figure 5 As shown, the third body 221 is provided with a positioning end face 221a, and the first body 121 is provided with a positioning portion 121a protruding toward the third body 221 along the first direction X, and the positioning portion 121a is used to abut with the positioning end face 221a. The first clamping portion 1 and the second clamping portion 2 can be pre-positioned by the abutment and cooperation between the positioning portion 121a and the positioning end face 221a to ensure the relative position relationship between the first clamping portion 1 and the second clamping portion 2, which is beneficial to improve the installation efficiency of the clamp 10. The first body 121 and the third body 221 can be fixedly connected by the first fastener 3 to achieve a fixed connection between the first clamping portion 1 and the second clamping portion 2. When the first fastener 3 is locked, the clamping effect of the first clamping portion 1 and the second clamping portion 2 on the lock edge 201 can also be improved, which is beneficial to improve the installation stability of the clamp 10. Among them, the first fastener 3 can be a bolt.

[0106] Next, the connection structure between the clamp 10 and the fixing member 40 is described in detail:

[0107] like Figure 1 and Figure 2 As shown, the fixing member 40 includes a first fixing member 40a and a second fixing member 40b which are independent of each other. The first clamping portion 1 also includes a first mounting portion 11, the first mounting portion 11 is used to provide support for the first fixing member 40a, along the second direction Y, one end of the first fixing member 40a is overlapped on the first mounting portion 11, and is fixedly connected to the first clamping portion 1 through the second fastener 4, and the other end of the first fixing member 40a is used to connect with the photovoltaic assembly 30. The second clamping portion 2 also includes a second mounting portion 21, the second mounting portion 21 is used to provide support for the second fixing member 40b, along the second direction Y, one end of the second fixing member 40b is overlapped on the second mounting portion 21, and is fixedly connected to the second clamping portion 2 through the third fastener 5, and the other end of the second fixing member 40b is used to connect with the photovoltaic assembly 30. Among them, the first fixing member 40a and the second fixing member 40b are respectively used to connect with two adjacent photovoltaic assemblies 30 along the second direction Y, so that the two adjacent photovoltaic assemblies 30 can be independently installed or disassembled without affecting each other. The second fastener 4 and the third fastener 5 are used to fix the first fixing member 40 a and the second fixing member 40 b on the clamp 10 , respectively, so as to improve the connection reliability between the first fixing member 40 a and the clamp 10 , and to improve the connection reliability between the second fixing member 40 b and the clamp 10 .

[0108] In the embodiment of the present application, the first mounting portion 11 and the first clamping arm 12 can be set as an integrated structure, and the second mounting portion 21 and the second clamping arm 22 can also be set as an integrated structure. In view of the above structural form, the present application provides two specific implementation methods. Figure 1 , Figure 4 and Figure 5 As shown, in the first embodiment, the first mounting portion 11 is connected to the second body 122, and the second mounting portion 21 is connected to the fourth body 222. The first body 121 and the third body 221 both extend along the third direction K, and the angle α between the third direction K and the first direction X satisfies 30°≤α<90°. Among them, α can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85° or 89°, and can be other values ​​within the above range, which is not limited in this embodiment.

[0109] In the present embodiment, the first body 121 and the third body 221 are both extended obliquely relative to the height direction Z of the clamp 10. When the angle α between the third direction K and the first direction X satisfies 30°≤α<90°, interference between the first fastener 3 and the second fastener 4 or the third fastener 5 can be avoided, providing more operating space, making it convenient for users to lock the second fastener 4 and the third fastener 5, thereby reducing the difficulty of installing the first fixing member 40a and the second fixing member 40b, which is beneficial to improving the installation efficiency of photovoltaic components.

[0110] like Figure 6 , Figure 7 and Figure 8 As shown, in the second embodiment, the first mounting portion 11 is connected to the first body 121, the second mounting portion 21 is connected to the third body 221, and the first body 121 and the third body 221 both extend along the height direction Z of the clamp 10. Compared with the first embodiment, the first body 121 and the third body 221 in this embodiment extend vertically along the height direction Z of the clamp 10, and the processing difficulty is relatively low, which is conducive to improving the processing efficiency of the first clamping portion 1 and the second clamping portion 2. In this embodiment, in order to avoid interference between the first fastener 3 and the second fastener 4 or the third fastener 5 in the first direction X, the size of the first mounting portion 12 and the second mounting portion 22 in the first direction X can be increased to provide more operating space for convenient locking of the first fastener 3.

[0111] Specifically, the dimension L1 of the first mounting portion 11 in the first direction X satisfies 40mm≤L1≤50mm, and L1 can be 40mm, 41mm, 42mm, 43mm, 44mm, 45mm, 46mm, 47mm, 48mm, 49mm or 50mm, or other values ​​within the above range, which is not limited in this embodiment. When L1 satisfies the above range, it can avoid interference between the first fastener 3 and the second fastener 4 in the first direction X, and will not cause the size of the clamp 10 in the first direction X to be too large. Similarly, the dimension L2 of the second mounting portion 21 in the first direction X satisfies 40mm≤L2≤50mm, and L2 can be 40mm, 41mm, 42mm, 43mm, 44mm, 45mm, 46mm, 47mm, 48mm, 49mm or 50mm, or other values ​​within the above range, which is not limited in this embodiment. When L2 satisfies the above range, interference between the first fastener 3 and the third fastener 5 in the first direction X can be avoided without causing the size of the clamp 10 in the first direction X to be too large.

[0112] In the above two embodiments, the first clamping portion 1 further includes a first reinforcing portion 13, and the two ends of the first reinforcing portion 13 are respectively fixedly connected to the first mounting portion 11 and the second body 122; and / or the second clamping portion 2 further includes a second reinforcing portion 23, and the two ends of the second reinforcing portion 23 are respectively fixedly connected to the second mounting portion 21 and the second clamping arm 22. Figure 7 As shown, the first reinforcing portion 13 can form a stable triangular structure with the first mounting portion 11 and the second body 122, which is beneficial to improving the structural strength and stability of the first clamping portion 1, thereby helping to increase the service life of the first clamping portion 1. Figure 8 As shown, the second reinforcing portion 23 can form a stable triangular structure with the second mounting portion 21 and the fourth body 222, which is beneficial to improving the structural strength and stability of the second clamping portion 2, thereby facilitating the service life of the second clamping portion 2. When the first reinforcing portion 13 and the second reinforcing portion 23 are provided at the same time, the structural stability of the clamp 10 can be further improved, thereby extending the service life of the clamp 10.

[0113] In addition, if Figure 4 and Figure 5As shown, a first limiting groove 111 is provided on a side of the first mounting portion 11 away from the first fixing member 40a, and at least a portion of the second fastener 4 is accommodated in the first limiting groove 111, and / or a second limiting groove 211 is provided on a side of the second mounting portion 21 away from the second fixing member 40b, and at least a portion of the third fastener 5 is accommodated in the second limiting groove 211. The first limiting groove 111 is used to limit the movement of the second fastener 4 in the first direction X to improve the installation stability of the second fastener 4, and can also achieve pre-positioning between the second fastener 4 and the first clamping portion 1, which is beneficial to improving the installation efficiency of the clamp 10. Similarly, the second limiting groove 211 is used to limit the movement of the third fastener 5 in the first direction X to improve the installation stability of the third fastener 5, and can also achieve pre-positioning between the third fastener 5 and the second clamping portion 2, which is beneficial to improving the installation efficiency of the clamp 10.

[0114] In the embodiment of the present application, the first mounting portion 11 and the first clamping arm 12 may also be configured as a split structure, and the second mounting portion 21 and the second clamping arm 22 may also be configured as a split structure. Fig. 9 , Fig.10 and Fig.11 As shown, the first clamping part 1 also includes a first mounting member 14, which is mounted on the first body 121 in an adjustable position along the height direction Z of the clamp 10, and the first mounting part 11 is arranged on the first mounting member 14. The second clamping part 2 also includes a second mounting member 24, which is mounted on the third body 221 in an adjustable position along the height direction Z of the clamp 10, and the second mounting part 22 is arranged on the second mounting member 24. When the clamp 10 adopts the above structure, the positions of the photovoltaic components 30 located on both sides of the clamp 10 in the height direction Z of the clamp 10 can be adjusted respectively, ensuring that the photovoltaic components 30 on both sides of the clamp 10 can be maintained at the same height. Moreover, a photovoltaic component 30 usually needs to be installed on the color steel tile 20 using multiple clamps 10 and fixing members 40. When the clamp 10 adopts the above structure, it can ensure that the installation heights of the clamps 10 connected to different positions of the same photovoltaic component 30 are consistent, thereby ensuring that the photovoltaic component 30 can be kept horizontal. In addition, when the installation surface of the photovoltaic component is inclined, the height positions of the first installation member 14 and the second installation member 15 can be adjusted to ensure that the two upper and lower adjacent rows of photovoltaic components 30 maintain the same inclination angle.

[0115] Specifically, the first mounting member 14 further includes a first connection portion 15 extending along the height direction Z of the clamp 10, and the second mounting member 24 further includes a second connection portion 25 extending along the height direction Z of the clamp 10. The first fastener 3 sequentially passes through the first connection portion 15, the first body 121, the third body 221 and the second connection portion 25 along the first direction X, so that the first mounting member 14, the first clamp arm 12, the second clamp arm 22 and the second mounting member 24 are fixedly connected, which can reduce the parts of the clamp 10 and simplify the structure of the clamp 10, thereby improving the installation efficiency of the photovoltaic component. More specifically, the first connecting portion 15 can be provided with a plurality of connection holes spaced along the height direction Z of the clamp 10, and the height adjustment of the first mounting member 14 can be achieved by adjusting different mounting holes to connect with the first fastener 3. Similarly, the second connecting portion 25 can also be provided with a plurality of connection holes spaced along the height direction Z of the clamp 10, and the height adjustment of the second mounting member 24 can be achieved by adjusting different mounting holes to connect with the first fastener 3.

[0116] Or, if Fig.10 and Fig.11 As shown, the first connecting portion 15 can be provided with a first waist-shaped hole 151 extending along the height direction Z of the clamp 10, and the height adjustment of the first mounting member 14 is achieved through the sliding cooperation between the first waist-shaped hole 151 and the first fastener 3. The second connecting portion 25 can also be provided with a second waist-shaped hole 251 extending along the height direction Z of the clamp 10, and the height adjustment of the second mounting member 24 is achieved through the sliding cooperation between the second waist-shaped hole 251 and the first fastener 3. In addition, the first waist-shaped hole 151 and the second waist-shaped hole 251 can respectively limit the first fastener 3 in the second direction Y, which is conducive to further improving the installation stability of the first fastener 3, thereby facilitating the installation stability of the clamp 10.

[0117] like Fig.10 and Fig.11 As shown, in this embodiment, the first mounting portion 11 may also be provided with a first limiting groove 111, and the second mounting portion 21 may also be provided with a second limiting groove 211, which will not be described in detail here.

[0118] Next, the connection structure between the first fixing member 40a, the second fixing member 40b and the photovoltaic assembly 30 is described in detail:

[0119] Combination Figure 3 and Fig.12As shown, the photovoltaic assembly 30 includes a laminate 301 and a frame 302. The photovoltaic assembly 30 includes a light-facing surface 30A and a backlight surface 30B that are relatively distributed along the thickness direction Z thereof. The light-facing surface 30A faces the light source and is used to receive direct sunlight. The backlight surface 30B faces away from the light source. The frame 302 is fixedly connected to the backlight surface 30B. The frame 302 can support the laminate 301, reducing the risk of the laminate 301 being damaged by external forces during transportation, installation, and use, thereby extending the service life of the laminate 301 and improving the overall rigidity and working stability of the photovoltaic assembly 30. Moreover, when the frame 302 is installed on the backlight surface 30B, it will not block the light-facing surface 30A, thereby increasing the effective area on the light-facing surface 30A for absorbing sunlight, thereby improving the absorption efficiency of the photovoltaic assembly 30 for sunlight, which is beneficial to improving the photoelectric conversion efficiency of the photovoltaic assembly 30, and further beneficial to improving the output power of the photovoltaic component. Among them, the frame 302 includes a first side 302A, a second side 302B and a third side 302C, the second side 302B is fixedly connected to the first side 302A and the third side 302C respectively, the first side 302A, the second side 302B and the third side 302C form a cavity 303D, and the first side 302A is bonded and fixed to the backlight surface 30B by structural adhesive 303.

[0120] Among them, combined Fig.13 As shown, the laminate 301 includes a battery layer 301A, a front plate 301B, a back plate 301C and a film layer 301D. The battery layer 301A includes a plurality of battery strings connected in series or in parallel, each battery string is formed by a plurality of battery cells 301Aa (including but not limited to monocrystalline silicon battery cells and polycrystalline silicon battery cells) connected in series, and two adjacent battery cells 301Aa are connected by welding strips 301Ab; the front plate 301B is located on the light-facing side of the battery layer 301A, and is used to protect the surface of the battery layer 301A and reduce the risk of damage to the battery cells 301Aa; the back plate 301C is located on the backlight side of the battery layer 301A, and has the function of blocking water vapor and insulating protection; the film layer 301D includes a first film layer 301Da and a second film layer 301 Db, along the thickness direction Z of the laminate 301, the first adhesive film layer 301Da is located between the front panel 301B and the battery layer 301A, and is used to achieve a fixed connection between the front panel 301B and the battery layer 301A, and the second adhesive film layer 301Db is located between the battery layer 301A and the back panel 301C, and is used to achieve a fixed connection between the battery layer 301A and the back panel 301C. The first adhesive film layer 301Da and the second adhesive film layer 301Db can also play a certain supporting and protective role for the battery layer 301A, ensuring that the photovoltaic module has good mechanical strength and reducing the impact of hail impact, wind, mechanical vibration and the like.

[0121] The present embodiment does not limit the structure of the battery cell 301Aa. The types of the battery cell 301Aa 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 battery, etc.

[0122] 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%.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] 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.

[0127] like Figure 1 and Figure 3 As shown, the first fixing member 40a is provided with a first connection portion 401, the second fixing member 40b is provided with a second connection portion 402, one of the two photovoltaic components 30 adjacent to each other along the second direction Y is connected to the first connection portion 401, and the other is connected to the second connection portion 402. Both the first connection portion 401 and the second connection portion 402 are curved structures, and the curved structures can extend into the cavity 302D, so that the two photovoltaic components 30 adjacent to each other along the second direction Y can form a movable connection with the first fixing member 40a and the second fixing member 40b respectively.

[0128] Specifically, when the first connection part 401 is connected to the frame 302, the first side 302A and the third side 302C are mutually limited with the first connection part 401 along the height direction Z of the clamp 10 to limit the movement of the photovoltaic assembly 30 along the height direction Z of the clamp 10; the second side 302A is limited with the first connection part 401 along the second direction Y to limit the movement of the photovoltaic assembly 30 along the second direction Y, which is conducive to improving the installation stability of the photovoltaic assembly 30. The first connection part 401 is also provided with a receiving space 403, and at least part of the third side 302C extends into the receiving space 403. The photovoltaic assembly 30 will deform under the action of external force (such as wind). For example, the middle part of the photovoltaic assembly 30 will be arched upward relative to the edge part. At this time, the frame 302 will have a tendency to rotate relative to the first fixing member 40a. If the frame 302 is fixedly connected to the first fixing member 40a, the edge part of the photovoltaic assembly 30 is prone to stress concentration, resulting in the fragmentation of the photovoltaic assembly 30, affecting the normal use of the entire photovoltaic component. Therefore, the embodiment of the present application can reduce the possibility of stress concentration and breakage of the photovoltaic component 30 at the connection position between the frame 302 and the first fixing component 40a when the photovoltaic component 30 is subjected to external force by movably connecting the first fixing component 40a with the frame 302, thereby helping to improve the reliability of the photovoltaic component 30 and extend the service life of the photovoltaic component 30.

[0129] The connection method between the second fixing member 40b and the frame 302 of another photovoltaic module 30 through the second connecting portion 402 is the same as the connection method between the first fixing member 40a and the frame 302 described above, which will not be repeated here.

[0130] In the embodiment of the present application, the extension direction of the first fixing member 40a and the second fixing member 40b is the second direction Y, that is, the extension direction of the first fixing member 40a and the second fixing member 40b is parallel to the length direction of the locking edge 201, which is conducive to reducing the size of the clamp 10 in the first direction X. Moreover, there is an overlapping part between the projections of the first fixing member 40a and the second fixing member 40b in the first direction X, which can reduce the size of the clamp 10 in the second direction Y, thereby reducing the distance between two adjacent photovoltaic components 30 in the second direction Y, which is conducive to increasing the installed capacity of the photovoltaic components 30 per unit area, thereby facilitating increasing the power generation power of the photovoltaic components.

[0131] In the above embodiments, the photovoltaic component further includes a first pressing block 50 and a second pressing block 60 which are independent of each other. Figure 1 and Figure 2As shown, the first pressing block 50 is arranged above the first fixing member 40a, and is fixedly connected with the first fixing member 40a and the first clamping portion 1 through the second fastener 4. The second pressing block 60 is arranged above the second fixing member 40b, and is fixedly connected with the second fixing member 40b and the second clamping portion 2 through the third fastener 5. Among them, the first pressing block 50 can cooperate with the first mounting portion 11 to limit the movement of the first fixing member 40a along the height direction Z of the clamp 10, which is beneficial to improve the installation stability of the first fixing member 40a. The second pressing block 60 can cooperate with the second mounting portion 21 to limit the movement of the second fixing member 40b along the height direction Z of the clamp 10, which is beneficial to improve the installation stability of the second fixing member 40b. Moreover, the first pressing block 50 and the second pressing block 60 respectively extend in directions away from each other along the second direction Y, so that the first pressing block 50 and the second pressing block 60 can respectively abut and cooperate with the second sides 302B of the two adjacent frames 302 along the second direction Y, so as to simultaneously limit the two adjacent photovoltaic components 30 along the second direction Y, which is beneficial to further improve the installation stability of the photovoltaic component 30 and reduce the risk of detachment of the photovoltaic component 30 from the fixing member 40.

[0132] Furthermore, a third waist-shaped hole 501 extending along the second direction Y can be provided on the first pressing block 50, and a fourth waist-shaped hole 601 extending along the second direction Y can be provided on the second pressing block 60, so that the photovoltaic assembly 30 can be installed and removed without disassembling the first pressing block 50 and the second pressing block 60, which is conducive to further improving the installation efficiency of the photovoltaic components. Specifically, the first clamping portion 1 and the second clamping portion 2 can be connected together by the first fastener 3 in advance, the first pressing block 50, the first fixing member 40a and the first clamping portion 1 can be connected together by the second fastener 4, and the second pressing block 60, the second fixing member 40b and the second clamping portion 2 can be connected together by the third fastener 5. During on-site installation, first clamp the clamp 10 on the locking edge 201, and then adjust the position of the first pressing block 50 in the second direction Y by slidingly matching the second fastener 4 with the third waist-shaped hole 501, and adjust the position of the second pressing block 60 in the second direction Y by slidingly matching the third fastener 5 with the fourth waist-shaped hole 601; after connecting the photovoltaic component 30 on one side to the first connecting part 401, adjust the position of the first pressing block 50 along the second direction Y to ensure that the first pressing block 50 can abut against the frame 302 of the photovoltaic component 30, and then lock the second fastener 4; then, after connecting the photovoltaic component 30 on the other side to the second connecting part 402, adjust the position of the second pressing block 60 along the second direction Y to ensure that the second pressing block 60 can abut against the frame 302 of the photovoltaic component 30, and then lock the third fastener 5. When the photovoltaic assembly 30 connected to the first connection portion 401 needs to be disassembled, it is only necessary to loosen the second fastener 4 and adjust the position of the first pressing block 50 in the second direction Y without disassembling the first pressing block 50. Similarly, when the photovoltaic assembly 30 connected to the second connection portion 402 needs to be disassembled, it is only necessary to loosen the third fastener 5 and adjust the position of the second pressing block 60 in the second direction Y without disassembling the second pressing block 60.

[0133] 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.
