The first clamping portion includes a first clamping arm, which is provided with a first body and a second body. The second clamping portion includes a second clamping arm, which is provided with a third body and a fourth body. The first body and the third body are fixedly connected by a first fastener.

[0008] In one possible implementation, the fixing member includes a first fixing member and a second fixing member; the first clamping part further includes a first mounting part, which is an integral structure with the first clamping arm, and the first fixing member overlaps with and is fixedly connected to the first mounting part; the second clamping part further includes a second mounting part, which is an integral structure with the second clamping arm, and the second fixing member overlaps with and is fixedly connected to the second mounting part; one of the two adjacent photovoltaic modules along the second direction is connected to the first fixing member, and the other is connected to the second fixing member.

[0010] In one possible implementation, the fixing member includes a first fixing member and a second fixing member; the first clamping part further includes a first mounting member, which is height-adjustably mounted on the first body, and has a first mounting portion, and the first fixing member overlaps with and is fixedly connected to the first mounting portion; the second clamping part further includes a second mounting member, which is height-adjustably mounted on the third body, and has a second mounting portion, and the second fixing member overlaps with and is fixedly connected to the second mounting portion; one of two adjacent photovoltaic modules along the second direction is connected to the first fixing member, and the other is connected to the second fixing member.

This is beneficial for improving the photoelectric conversion efficiency of the photovoltaic module, and consequently, for increasing the output power of the photovoltaic module. The fastener connects the clamp to the photovoltaic module along the second direction, eliminating the need for the photovoltaic module's width to match the width of the corrugated steel sheet. This allows the photovoltaic module to be adapted to corrugated steel sheets of different widths, providing greater flexibility.

[0093] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0094] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0095] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0096] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0097] This application provides a photovoltaic component, such as... Figure 1 , Figure 2 and Figure 3 As shown, the photovoltaic component includes a clamp 10, a corrugated steel sheet 20, a photovoltaic module 30, and a fastener 40. Multiple corrugated steel sheets 20 are installed on the ground or building structure via supports 70. Two adjacent corrugated steel sheets 20 overlap along the first direction X and are bent to form a locking edge 201. The clamp 10 includes a clamping part 101, which clamps the locking edge 201 along the first direction X, thus fixing the clamp 10 to the corrugated steel sheet 20. The fastener 40 is connected at both ends along the second direction Y to the clamping part 101 and the photovoltaic module 30, respectively, to install the photovoltaic module 30 on the corrugated steel sheet 20, facilitating the use of solar energy to meet daily usage needs. The building structure includes, but is not limited to, the roof and walls of production facilities such as factories and warehouses. This embodiment uses the roof as an example for illustration.

[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 module 30 is parallel to the length direction (second direction Y) of the locking edge 201, and the fastener 40 connects the clamp 10 and the photovoltaic module 30 along the second direction Y. It is not necessary for the width of the photovoltaic module 30 to be consistent with the width of the color steel tile 20, so that the photovoltaic module 30 can be adapted to color steel tiles 20 with different widths. That is, this embodiment does not limit the shape and structure of the color steel tile 20, and has a high degree of flexibility.

[0100] The connection structure between clamp 10 and color steel sheet 20 will be described in detail below:

[0101] like Figure 2 As shown, the clamp 10 includes a first clamping part 1 and a second clamping part 2 distributed opposite to each other along a first direction X. The first clamping part 1 and the second clamping part 2 are used to jointly clamp the locking edge 201 of the color steel tile 20, 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, which includes a first body 121 and a second body 122; the second clamping part 2 is provided with a second clamping arm 22, which includes a third body 221 and a fourth body 222. Both the second body 122 and the fourth body 222 extend along the height direction Z of the clamp 10. Along the first direction X, a clamping space 120 is formed between the second body 122 and the fourth body 222. At least a portion of the locking edge 201 is accommodated within the clamping space 120, so that the second body 122 and the fourth body 222 can jointly clamp the locking edge 201 along the first direction X, achieving a stable connection between the clamp 10 and the color steel tile 20. A corrugated structure 223 may be provided on the surface of the second body 122 facing the clamping space 120 and / or the surface of the fourth body 222 facing the clamping space 120. The corrugated structure 223 can increase the friction between the locking edge 201 and the clamp 10, which is beneficial to improve the installation stability of the clamp 10, reduce the risk of the clamp 10 moving relative to the locking edge 201, and thus improve the connection reliability between the clamp 10 and the locking edge 201.

[0102] In one specific implementation, such as Figure 2 and Figure 4 As shown, along the height direction Z of the clamp 10, the second body 122 has a first extension section 123 at the end away from the first body 121. The first extension section 123 extends along the first direction X toward 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, thereby improving the clamping of the locking edge 201 by the clamp 10. On the other hand, the first extension section 123 can overlap the surface of the color steel tile 20, which helps to improve the structural stability of the first clamping part 1 and reduce the risk of the first clamping part 1 tilting, thereby improving the installation stability of the clamp 10.

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

[0104] In one specific implementation, such as Figure 2 and Figure 5 As shown, along the height direction Z of the clamp 10, the fourth body 222 has a second extension section 224 at the end away from the third body 221. The second extension section 224 extends along 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 sheet 20, which helps to improve the structural stability of the second clamping part 2, reduce the risk of the second clamping part 2 tilting, and thus help to improve the installation stability of the clamp 10.

[0105] In one specific implementation, such as 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 part 121a protruding towards the third body 221 along the first direction X. The positioning part 121a is used to abut against the positioning end face 221a. The first clamping part 1 and the second clamping part 2 can be pre-positioned through the abutment between the positioning part 121a and the positioning end face 221a to ensure the relative positional relationship between the first clamping part 1 and the second clamping part 2, which is beneficial to improving the installation efficiency of the fixture 10. The first body 121 and the third body 221 can be fixedly connected by a first fastener 3 to achieve a fixed connection between the first clamping part 1 and the second clamping part 2. When the first fastener 3 is tightened, it can also improve the clamping effect of the first clamping part 1 and the second clamping part 2 on the locking edge 201, which is beneficial to improving the installation stability of the fixture 10. Specifically, the first fastener 3 can be a bolt.

[0106] Next, the connection structure between the clamp 10 and the fixing member 40 will be 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 that are independent of each other. The first clamping part 1 also includes a first mounting part 11, which provides support for the first fixing member 40a. Along the second direction Y, one end of the first fixing member 40a overlaps the first mounting part 11 and is fixedly connected to the first clamping part 1 by a second fastener 4. The other end of the first fixing member 40a is used to connect to the photovoltaic module 30. The second clamping part 2 also includes a second mounting part 21, which provides support for the second fixing member 40b. Along the second direction Y, one end of the second fixing member 40b overlaps the second mounting part 21 and is fixedly connected to the second clamping part 2 by a third fastener 5. The other end of the second fixing member 40b is used to connect to the photovoltaic module 30. The first fixing member 40a and the second fixing member 40b are respectively used to connect to two adjacent photovoltaic modules 30 along the second direction Y, so that the two adjacent photovoltaic modules 30 can be installed or removed independently without affecting each other. The second fastener 4 and the third fastener 5 are used to fix the first fixing member 40a and the second fixing member 40b to the clamp 10, respectively, so as to improve the connection reliability between the first fixing member 40a and the clamp 10 and the connection reliability between the second fixing member 40b and the clamp 10.

[0108] In this embodiment, the first mounting part 11 and the first clamping arm 12 can be configured as an integral structure, and the second mounting part 21 and the second clamping arm 22 can also be configured as an integral structure. For the above structural forms, this application provides two specific implementation methods. For example... Figure 1 , Figure 4 and Figure 5 As shown, in the first embodiment, the first mounting part 11 is connected to the second body 122, and the second mounting part 21 is connected to the fourth body 222. Both the first body 121 and the third body 221 extend along a third direction K, and the angle α between the third direction K and the first direction X satisfies 30° ≤ α < 90°. Specifically, 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; this embodiment does not limit this.

[0109] In this embodiment, both the first body 121 and the third body 221 extend at an inclination 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 and making it easier for users to lock the second fastener 4 and the third fastener 5. This reduces the installation difficulty of 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 part 11 is connected to the first body 121, and the second mounting part 21 is connected to the third body 221. Both the first body 121 and the third body 221 extend along the height direction Z of the clamp 10. Compared to the first embodiment, in this embodiment, the first body 121 and the third body 221 extend vertically along the height direction Z of the clamp 10, which reduces the processing difficulty and is beneficial to improving the processing efficiency of the first clamping part 1 and the second clamping part 2. In this embodiment, to avoid interference between the first fastener 3 and the second fastener 4 or the third fastener 5 in the first direction X, the dimensions of the first mounting part 12 and the second mounting part 22 along the first direction X can be increased to provide more operating space and facilitate locking the first fastener 3.

[0111] Specifically, the dimension L1 of the first mounting part 11 in the first direction X satisfies 40mm ≤ L1 ≤ 50mm. L1 can specifically be 40mm, 41mm, 42mm, 43mm, 44mm, 45mm, 46mm, 47mm, 48mm, 49mm, or 50mm, or other values ​​within the above range. This embodiment does not impose any restrictions on this value. When L1 satisfies the above range, interference between the first fastener 3 and the second fastener 4 in the first direction X can be avoided, and the size of the clamp 10 in the first direction X will not be excessive. Similarly, the dimension L2 of the second mounting part 21 in the first direction X satisfies 40mm ≤ L2 ≤ 50mm. L2 can specifically be 40mm, 41mm, 42mm, 43mm, 44mm, 45mm, 46mm, 47mm, 48mm, 49mm, or 50mm, or other values ​​within the above range. This embodiment does not impose any restrictions on this value. When L2 meets the above range, it can avoid interference between the first fastener 3 and the third fastener 5 in the first direction X, and will not cause the size of the clamp 10 in the first direction X to be too large.

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

[0113] In addition, such as Figure 4 and Figure 5As shown, the first mounting portion 11 has a first limiting groove 111 on the side 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. Alternatively, the second mounting portion 21 has a second limiting groove 211 on the side 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 restricts the movement of the second fastener 4 in the first direction X, thereby improving the installation stability of the second fastener 4. It also enables pre-positioning between the second fastener 4 and the first clamping portion 1, which is beneficial for improving the installation efficiency of the clamp 10. Similarly, the second limiting groove 211 restricts the movement of the third fastener 5 in the first direction X, thereby improving the installation stability of the third fastener 5. It also enables pre-positioning between the third fastener 5 and the second clamping portion 2, which is beneficial for improving the installation efficiency of the clamp 10.

[0114] In this embodiment, the first mounting part 11 and the first clamping arm 12 can also be configured as separate structures, and the second mounting part 21 and the second clamping arm 22 can also be configured as separate structures. Specifically, as shown in the following example... Figure 9 , Figure 10 and Figure 11 As shown, the first clamping part 1 further includes a first mounting member 14, which is adjustablely mounted on the first body 121 along the height direction Z of the clamp 10, and a first mounting part 11 is disposed on the first mounting member 14. The second clamping part 2 further includes a second mounting member 24, which is adjustablely mounted on the third body 221 along the height direction Z of the clamp 10, and a second mounting part 22 is disposed on the second mounting member 24. When the clamp 10 adopts the above structure, the positions of the photovoltaic modules 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 modules 30 on both sides of the clamp 10 can be kept at the same height. Moreover, a photovoltaic module 30 usually needs to be installed on the color steel tile 20 using multiple clamps 10 and fasteners 40. When the clamp 10 adopts the above structure, it can ensure that the installation height of the clamps 10 connected to different positions of the same photovoltaic module 30 is consistent, thereby ensuring that the photovoltaic module 30 can be kept horizontal. In addition, when the mounting surface of the photovoltaic component is tilted, the height of the first mounting component 14 and the second mounting component 15 can be adjusted to ensure that the two adjacent rows of photovoltaic modules 30 maintain the same tilt angle.

[0115] Specifically, the first mounting member 14 further includes a first connecting portion 15 extending along the height direction Z of the clamp 10, and the second mounting member 24 further includes a second connecting portion 25 extending along the height direction Z of the clamp 10. The first fastener 3 passes sequentially through the first connecting portion 15, the first body 121, the third body 221, and the second connecting portion 25 along the first direction X, so that the first mounting member 14, the first clamping arm 12, the second clamping arm 22, and the second mounting member 24 are fixedly connected. This reduces the number of parts in the clamp 10, simplifies the structure of the clamp 10, and improves the installation efficiency of the photovoltaic components. More specifically, the first connecting portion 15 may be provided with multiple connecting holes spaced apart along the height direction Z of the clamp 10. The height of the first mounting member 14 can be adjusted by adjusting the connection of different mounting holes with the first fastener 3. Similarly, the second connecting portion 25 may also be provided with multiple connecting holes spaced apart along the height direction Z of the clamp 10. The height of the second mounting member 24 can be adjusted by adjusting the connection of different mounting holes with the first fastener 3.

[0116] Or, such as Figure 10 and Figure 11 As shown, the first connecting portion 15 may be provided with a first oblong hole 151 extending along the height direction Z of the clamp 10. The height adjustment of the first mounting member 14 is achieved through the sliding engagement of the first oblong hole 151 with the first fastener 3. The second connecting portion 25 may also be provided with a second oblong hole 251 extending along the height direction Z of the clamp 10. The height adjustment of the second mounting member 24 is achieved through the sliding engagement of the second oblong hole 251 with the first fastener 3. In addition, the first oblong hole 151 and the second oblong hole 251 can respectively limit the first fastener 3 in the second direction Y, which is beneficial to further improve the installation stability of the first fastener 3, thereby improving the installation stability of the clamp 10.

[0117] like Figure 10 and Figure 11 As shown, in this embodiment, the first mounting part 11 may also be provided with a first limiting groove 111 and the second mounting part 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 module 30 will be described in detail:

[0119] Combination Figure 3 and Figure 12As shown, the photovoltaic module 30 includes a laminate 301 and a frame 302. The photovoltaic module 30 includes a light-facing surface 30A and a back-lighting surface 30B, which are relatively distributed along its thickness direction Z. The light-facing surface 30A faces the light source and is used to receive direct sunlight, while the back-lighting surface 30B faces away from the light source. The frame 302 is fixedly connected to the back-lighting surface 30B. The frame 302 supports the laminate 301, reducing the risk of damage to the laminate 301 from external forces during transportation, installation, and use, thereby extending the service life of the laminate 301 and improving the overall rigidity and operational stability of the photovoltaic module 30. Furthermore, when the frame 302 is installed on the back-lighting surface 30B, it does not obstruct the light-facing surface 30A, thereby increasing the effective area on the light-facing surface 30A for absorbing sunlight, thus improving the photovoltaic module 30's absorption efficiency of sunlight, which is beneficial for improving the photovoltaic conversion efficiency of the photovoltaic module 30, and consequently, improving the output power of the photovoltaic module. 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. The first side 302A is bonded and fixed to the backlight surface 30B by structural adhesive 303.

[0120] Among them, combined Figure 13 As shown, the laminate 301 includes a battery layer 301A, a front panel 301B, a back panel 301C, and an encapsulant layer 301D. The battery layer 301A comprises multiple battery strings connected in series or parallel. Each battery string consists of multiple battery cells 301Aa (including but not limited to monocrystalline silicon cells and polycrystalline silicon cells) connected in series, with adjacent battery cells 301Aa connected by solder ribbons 301Ab. The front panel 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 panel 301C is located on the shaded side of the battery layer 301A and has the functions of blocking moisture and providing insulation protection. The encapsulant layer 301D includes a first encapsulant layer 301Da and a second encapsulant layer 301Aa. Along the thickness direction Z of the laminate 301, the first encapsulant layer 301Da is located between the front panel 301B and the battery layer 301A, and is used to fix the front panel 301B and the battery layer 301A. The second encapsulant layer 301Db is located between the battery layer 301A and the back panel 301C, and is used to fix the battery layer 301A and the back panel 301C. The first encapsulant layer 301Da and the second encapsulant layer 301Db can also provide a certain degree of support and protection for the battery layer 301A, ensuring that the photovoltaic module has good mechanical strength and reducing the impact of hail, wind, mechanical vibration and other conditions.

[0121] This embodiment does not limit the structure of the battery cell 301Aa. The types of battery cells 301Aa include, but are not limited to, passivated emitter rear cell (PERC), tunnel oxide passivated contact (TOPCon), intrinsic thin-film heterojunction (HJT), interdigitated back contact (IBC), perovskite cells, etc.

[0122] For PERC cells, along their thickness direction, the PERC cell sequentially includes a front-surface silver electrode, a front-surface silicon nitride passivation layer, a phosphorus emitter layer, a P-type substrate silicon layer, a localized aluminum back field, a metallic aluminum back electrode, and a back passivation layer (Al2O3 / SiNx). PERC cells use a passivation film to passivate the back side, replacing the all-aluminum back field, enhancing light reflection within the silicon substrate, reducing the recombination rate on the back side, and improving the cell efficiency by 0.5%-1%.

[0123] For TOPCon cells, along their thickness direction, the TOPCon cell sequentially includes a silver electrode, a front-surface silicon nitride passivation layer, a boron-doped emitter, an N-type substrate silicon layer, a diffused doped layer, an ultrathin silicon oxide layer, doped polycrystalline silicon, silicon nitride, and the silver electrode. The back of the cell consists of an ultrathin silicon oxide layer (1nm–2nm) and a phosphorus-doped microcrystalline amorphous mixed Si film, which together form a passivation contact structure. This structure can block minority carrier recombination, increasing the cell's open-circuit voltage and short-circuit current. The ultrathin oxide layer allows majority carrier electrons to tunnel into the polycrystalline silicon layer while blocking minority carrier recombination. The excellent passivation effect of the ultrathin silicon oxide and heavily doped silicon film causes band bending on the silicon wafer surface, resulting in a field passivation effect. This significantly increases the probability of electron tunneling, reduces contact resistance, and improves the cell's open-circuit voltage and short-circuit current, thereby increasing the cell's conversion efficiency.

[0124] For an HJT cell, along its thickness direction, the HJT cell sequentially includes a front low-temperature silver electrode, a front conductive film, an N-type amorphous silicon film, an intrinsic amorphous silicon film, an N-type substrate silicon layer, an intrinsic amorphous silicon film, a P-type amorphous silicon film, a back conductive film, and a back low-temperature silver electrode.

[0125] For an IBC cell, along its thickness direction, it sequentially includes a silicon nitride inversion layer, an N+ front surface field, an N-type substrate silicon layer, a P+ emitter, an N+ back field, an aluminum oxide passivation layer, a silicon nitride antireflection layer, and a silver electrode. IBC cells utilize ion implantation technology to obtain P- and N-regions with good uniformity and precisely controllable junction depth. The absence of grid lines on the front side eliminates light-blocking current loss from the metal electrodes, maximizing the utilization of incident photons and improving short-circuit current by approximately 7% compared to conventional solar cells. Due to its back-contact structure, grid line shading is not a concern, allowing for a wider grid line ratio, thus reducing series resistance and achieving a high fill factor. Optimized design of surface passivation and light-trapping structures can be achieved, resulting in lower front surface recombination rates and surface reflection.

[0126] For a perovskite solar cell, along its thickness direction, it sequentially comprises a substrate material, a conductive thin film, an electron transport layer (titanium dioxide), a perovskite absorption layer (hole transport layer), and a metal cathode. Perovskite materials possess a high light absorption coefficient and a long carrier diffusion distance. After the photons absorbed by the perovskite material are converted into electrons, they are easily collected by the electrodes with minimal loss, thus generating high photogenerated voltage and current, resulting in high photoelectric conversion efficiency.

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

[0128] Specifically, when the first connecting part 401 is connected to the frame 302, the first side 302A and the third side 302C cooperate with the first connecting part 401 along the height direction Z of the clamp 10 to limit the movement of the photovoltaic module 30 along the height direction Z of the clamp 10; the second side 302A cooperates with the first connecting part 401 along the second direction Y to limit the movement of the photovoltaic module 30 along the second direction Y, which helps to improve the installation stability of the photovoltaic module 30. The first connecting part 401 is also provided with a receiving space 403, and at least a portion of the third side 302C extends into the receiving space 403. The photovoltaic module 30 will deform under the action of external force (such as wind). For example, the middle part of the photovoltaic module 30 will arch 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, stress concentration will easily occur at the edge part of the photovoltaic module 30, causing the photovoltaic module 30 to break and affecting the normal use of the entire photovoltaic component. Therefore, by movably connecting the first fixing member 40a to the frame 302, the present application embodiment can reduce the possibility of stress concentration and breakage of the photovoltaic module 30 at the connection position between the frame 302 and the first fixing member 40a when the photovoltaic module 30 is subjected to external force, thereby improving the reliability of the photovoltaic module 30 and extending its service life.

[0129] The connection method between the second fastener 40b and the frame 302 of the other photovoltaic module 30 via the second connecting part 402 is the same as the connection method between the first fastener 40a and the frame 302 described above, and will not be repeated here.

[0130] In this embodiment, 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 beneficial to reducing the size of the clamp 10 in the first direction X. Moreover, the projections of the first fixing member 40a and the second fixing member 40b in the first direction X have an overlapping portion, which can reduce the size of the clamp 10 in the second direction Y, thereby reducing the spacing between two adjacent photovoltaic modules 30 in the second direction Y, which is beneficial to increasing the installed capacity of photovoltaic modules 30 per unit area, thereby improving the power generation power of the photovoltaic components.

[0131] In the above embodiments, the photovoltaic component also includes a first pressing block 50 and a second pressing block 60 that are independent of each other, such as Figure 1 and Figure 2As shown, the first pressure block 50 is disposed above the first fixing member 40a and is fixedly connected to the first fixing member 40a and the first clamping part 1 by the second fastener 4. The second pressure block 60 is disposed above the second fixing member 40b and is fixedly connected to the second fixing member 40b and the second clamping part 2 by the third fastener 5. The first pressure block 50 can cooperate with the first mounting part 11 to restrict the movement of the first fixing member 40a along the height direction Z of the clamp 10, which helps improve the installation stability of the first fixing member 40a. The second pressure block 60 can cooperate with the second mounting part 21 to restrict the movement of the second fixing member 40b along the height direction Z of the clamp 10, which helps improve the installation stability of the second fixing member 40b. Moreover, the first pressing block 50 and the second pressing block 60 extend along the second direction Y in a direction away from each other, so that the first pressing block 50 and the second pressing block 60 can respectively abut and cooperate with the second side 302B of the two adjacent frame 302 along the second direction Y, so as to simultaneously limit the two photovoltaic modules 30 adjacent along the second direction Y, which is conducive to further improving the installation stability of the photovoltaic module 30 and reducing the risk of the photovoltaic module 30 detaching from the fixing member 40.

[0132] Furthermore, a third oblong hole 501 extending along the second direction Y can be provided on the first pressing block 50, and a fourth oblong hole 601 extending along the second direction Y can be provided on the second pressing block 60. This allows the installation and removal of the photovoltaic module 30 without disassembling the first pressing block 50 and the second pressing block 60, which is beneficial to further improve the installation efficiency of the photovoltaic components. Specifically, the first clamping part 1 and the second clamping part 2 can be connected together in advance by the first fastener 3, the first pressing block 50, the first fixing member 40a and the first clamping part 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 part 2 can be connected together by the third fastener 5. During on-site installation, first clamp the clamp 10 onto the locking edge 201. Then, adjust the position of the first pressure block 50 in the second direction Y by sliding the second fastener 4 with the third oblong hole 501, and adjust the position of the second pressure block 60 in the second direction Y by sliding the third fastener 5 with the fourth oblong hole 601. After connecting one side of the photovoltaic module 30 to the first connecting part 401, adjust the position of the first pressure block 50 along the second direction Y to ensure that the first pressure block 50 can abut against the frame 302 of the photovoltaic module 30, and then tighten the second fastener 4. Next, connect the other side of the photovoltaic module 30 to the second connecting part 402, adjust the position of the second pressure block 60 along the second direction Y to ensure that the second pressure block 60 can abut against the frame 302 of the photovoltaic module 30, and then tighten the third fastener 5. When it is necessary to disassemble the photovoltaic module 30 connected to the first connecting part 401, it is only necessary to loosen the second fastener 4 and adjust the position of the first pressure block 50 in the second direction Y without disassembling the first pressure block 50. Similarly, when it is necessary to disassemble the photovoltaic module 30 connected to the second connecting part 402, it is only necessary to loosen the third fastener 5 and adjust the position of the second pressure block 60 in the second direction Y without disassembling the second pressure block 60.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
