[0008] In one embodiment, the connector includes a first connecting structure and a second connecting structure. One end of the first connecting structure is hinged to one end of the second connecting structure. The end of the first connecting structure opposite to the second connecting structure is hinged to the side wall of the first component parallel to the corrugated steel sheet. The end of the second connecting structure opposite to the first connecting structure is hinged to the side wall of the second component parallel to the corrugated steel sheet.

[0009] In one embodiment, one end of the first connecting structure is provided with one of a second slot or a second protrusion, and one end of the second connecting structure is provided with the other of a second slot or a second protrusion, wherein the second protrusion is rotatably engaged with the second slot.

[0010] In one embodiment, one end of the first connecting structure is provided with a first mounting cylinder, and one end of the second connecting structure is provided with a second mounting cylinder. The first mounting cylinder and the second mounting cylinder are arranged along the same straight line. The connecting member further includes a rotating shaft, which passes through the first mounting cylinder and the second mounting cylinder. The first connecting structure and the second connecting structure can rotate relative to each other around the rotating shaft.

[0011] In one embodiment, the two ends of the rotating shaft are respectively connected to limit structures, which are used to restrict the rotating shaft from moving axially.

[0012] In one embodiment, at least one end of the rotating shaft is provided with a fixing cap, and the fixing cap is provided with a plurality of limiting blocks, which are arranged at intervals around the rotating shaft; the first connecting structure and the second connecting structure can be inserted between any two adjacent limiting blocks.

Furthermore, the hinged connection allows the connector to be rotatably mounted relative to the first component and the second component, enabling the connector to stably connect the first and second components, which are staggered in height. This ensures that the first and second components, even with a height difference, can stably form a whole, guaranteeing full contact installation between the photovoltaic modules and the roof or roof surface. This effectively reduces cantilever between adjacent components, allowing the photovoltaic modules to be stepped on, reducing the need for maintenance steps, lowering the construction cost of the photovoltaic system, and simultaneously increasing the installation area of ​​the photovoltaic modules, thus improving the practicality and structural reliability of the photovoltaic system.

[0037] In related technologies, photovoltaic (PV) modules can be installed and fixed to corrugated steel roofs using clamps, clamps, and other mounting components. This ensures that the PV modules are stably oriented towards the light source, guaranteeing the stable conversion of solar energy by the PV system. In existing PV systems, since most PV modules do not meet the requirements for being stepped on, maintenance platforms are usually installed next to the modules for users to clean or maintain them. However, these maintenance platforms occupy a significant amount of space, reducing the area that can be used to install the PV modules and increasing the construction cost of the PV system to some extent.

[0038] It should be noted that in existing photovoltaic (PV) systems, PV modules are mostly installed independently on corrugated steel roofs using clamps, clamps, and other mounting components. These corrugated steel roofs can be the building's roof or wall, and the mounting components connect to the corrugated steel sheets to support the PV modules. However, because the dimensions of the corrugated steel sheets and the PV modules are often mismatched, unsupported cantilevered sections often exist between adjacent modules along the adjacent edges perpendicular to the corrugated steel sheets. The structural strength at these cantilevered sections is low, meaning the PV modules cannot adequately meet the structural strength requirements for being stepped on. Therefore, to facilitate regular cleaning or maintenance of the PV modules on the roof, maintenance platforms are usually installed next to the modules, allowing users to move around and perform cleaning or maintenance. However, the installation of these platforms increases the construction materials used in the PV system, raising construction costs. Furthermore, the platforms require installation space, impacting the area where PV modules can be installed, resulting in a lower installation rate on the roof. To address the aforementioned issues, this application proposes a photovoltaic system 100.

[0039] Please see Figures 1 to 4 In one embodiment of this application, the photovoltaic system 100 includes a photovoltaic module 10 and a connector 30. The photovoltaic module 10 includes a first component 11 and a second component 13, which are arranged at intervals. Both the first component 11 and the second component 13 include a frame. The photovoltaic module 10 has a height direction. The connector 30 has a first end and a second end. The first end is hinged to the side wall of the first component 11 parallel to the frame of the corrugated steel sheet 200, and the second end is hinged to the side wall of the second component 13 parallel to the frame of the corrugated steel sheet 200.

[0040] In this application, the first component 11 and the second component 13 can be components with the same attributes such as model, material, size, and installation direction. Of course, the first component 11 and the second component 13 can also be components with different attributes such as model, material, size, and installation direction. By using the first end of the connector 30 to be hinged to the side wall of the frame of the first component 11 and the second end of the connector 30 to be hinged to the side wall of the frame of the second component 13, the first component 11 and the second component 13 can be connected into a whole under the strong connection of the connector 30, so as to realize the overall assembly of the photovoltaic module 10 on the roof or roof surface and enhance the overall structural strength of the photovoltaic module 10.

[0041] Thus, under the connecting action of connector 30, the two adjacent components can be connected and supported at the edge cantilever, effectively enhancing the structural strength of the two adjacent components at the cantilever, so that the photovoltaic module 10 as a whole can better meet the function of being stepped on, and facilitates the reduction of the installation of maintenance pedals.

[0042] The photovoltaic module 10 can be directly placed on the corrugated steel sheet 200 to reduce the bottom clearance of the photovoltaic module 10 and improve the overall structural strength of the photovoltaic module 10. The photovoltaic system 100 can install the photovoltaic module 10 horizontally, that is, with the long side of the photovoltaic module 10 perpendicular to the corrugation direction of the corrugated steel sheet 200. In this case, the connector 30 can connect the short side of the frame of the first module 11 to the short side of the frame of the second module 13, enhancing the overall structural assembly stability and reliability of the photovoltaic module 10. Alternatively, the photovoltaic system 100 can also install the photovoltaic module 10 vertically on the roof or roof surface of the corrugated steel sheet 200, that is, with the short side of the photovoltaic module 10 perpendicular to the corrugation direction of the corrugated steel sheet 200. In this case, the connector 30 can connect the first module 11... The long side of the frame of the first component 11 is aligned with the long side of the frame of the second component 13, which enhances the overall structural assembly stability and reliability of the photovoltaic module 10. In addition, the photovoltaic system 100 can also install the photovoltaic module 10 using a combination of horizontal and vertical installation, so that the installation directions of some adjacent first components 11 and second components 13 are perpendicular. In this case, the connector 30 can be connected to the long side of the frame of the first component 11 and the short side of the frame of the second component 13, or the connector 30 can be connected to the short side of the frame of the first component 11 and the long side of the frame of the second component 13, so as to better enhance the overall structural assembly stability and reliability of the photovoltaic module 10.

[0043] Because roofs constructed with materials such as corrugated steel sheets (e.g., 200mm thick) often lack a perfectly flat corrugated surface, the photovoltaic modules 10 installed on the roof are prone to misalignment in the height direction between the first module 11 and the second module 13, resulting in a height difference between them. Therefore, by hinged to the first end of the connector 30 with the sidewall of the first module 11 (this hinge structure can be achieved using a rotatable latching mechanism or a hinge structure), the connector 30 and the first module 11 can be rotated relative to each other. Simultaneously, by hinged to the second end of the connector 30 with the sidewall of the second module 13 (this hinge structure can also be achieved using a rotatable latching mechanism or a hinge structure), the connector 30 and the second module 13 can be rotated relative to each other. By utilizing the connector 30, which is rotatably mounted relative to the first component 11 and the second component 13, the connector 30 can be tilted to connect the first component 11 and the second component 13, which have a certain height difference. This avoids the inability to connect properly due to the height difference between the first component 11 and the second component 13, allowing the photovoltaic module 10 to be stably connected to form a whole. This ensures full contact between the photovoltaic module 10 and the roof or roof surface, preventing some components from being suspended in the air. It also helps to better enhance the overall structural strength of the photovoltaic module 10, giving it better overall wind uplift resistance. At the same time, it allows the photovoltaic module 10 to better realize the function of being stepped on, reducing the need for maintenance footboards in the photovoltaic system 100, and effectively improving the practicality and structural reliability of the photovoltaic system 100.

[0044] It is understood that there may be two, three, four, or other connectors 30 between the first component 11 and the second component 13 of the photovoltaic module 10. This application does not limit the number of connectors 30 between the first component 11 and the second component 13. Users can set an appropriate number of connectors 30 according to the length of the module frame to better improve the overall structural strength of the photovoltaic module 10.

[0045] In one embodiment of this application, by using the first end and the second end of the connector 30 to be hinged to the sidewall of the first component 11 parallel to the corrugated sidewall of the color steel tile 200 and the second component 13 parallel to the sidewall of the corrugated sidewall of the color steel tile 200, the photovoltaic module 10 can be formed as a whole under the strong connection effect of the connector 30, thereby enhancing the overall structural strength of the photovoltaic module 10 and improving the wind resistance of the photovoltaic system 100. Furthermore, by utilizing the hinged connection method, the connector 30 can be rotatably set relative to the first component 11, and the connector 30 can be rotatably set relative to the second component 13. This allows the connector 30 to stably connect the first component 11 and the second component 13, which are misaligned in the height direction. This ensures that the first component 11 and the second component 13, which have a height difference, can also stably form a whole, guaranteeing full contact installation between the photovoltaic module 10 and the roof or roof surface. This effectively reduces the cantilever between adjacent components, and enables the photovoltaic module 10 as a whole to achieve the function of being stepped on. This helps to reduce the setting of maintenance steps, lower the construction cost of the photovoltaic system 100, and at the same time, it can better increase the installation area of ​​the photovoltaic module 10, and improve the practicality and structural reliability of the photovoltaic system 100.

[0046] In one embodiment of this application, the first component 11 has a frame sidewall parallel to the corrugations of the color steel sheet 200, which is provided with one of a first slot 10a or a first protrusion 30a, and the first end is provided with the other of the first slot 10a or the first protrusion 30a. The first protrusion 30a is rotatably inserted into the first slot 10a.

[0047] In this embodiment, by providing a first slot 10a on the sidewall of the first component 11, a first protrusion 30a can be provided at the first end of the connector 30. The first protrusion 30a can be a protrusion structure that matches the shape of the first slot 10a. For example, the first protrusion 30a can be a spherical or cylindrical protrusion structure, and the first slot 10a can be a corresponding spherical or cylindrical groove. This allows the first protrusion 30a to be stably inserted into the first slot 10a and to rotate along the height direction within the first slot 10a, thereby achieving the hinge connection between the connector 30 and the first component 11 and further improving the connection stability and reliability between the connector 30 and the first component 11. In addition, the first component 11 can be provided with a first protrusion 30a on the side wall of the frame, and the first end of the connector 30 can be provided with a first slot 10a. By using the first protrusion 30a and the first slot 10a to cooperate and insert, the first component 11 and the connector 30 can be assembled together, thereby further improving the structural stability and reliability of the photovoltaic system 100.

[0048] In some embodiments, the second component 13 has one of a first slot 10a or a first protrusion 30a on its frame sidewall parallel to the corrugations of the color steel sheet 200, and the second end has the other of a first slot 10a or a first protrusion 30a, with the first protrusion 30a rotatably inserted into the first slot 10a.

[0049] In this embodiment, by providing a first slot 10a on the sidewall of the second component 13, a first protrusion 30a can be provided at the second end of the connector 30. This first protrusion 30a can be a protrusion structure that matches the shape of the first slot 10a. For example, the first protrusion 30a can be a spherical or cylindrical protrusion structure, and the first slot 10a can be a corresponding spherical or cylindrical groove. This allows the first protrusion 30a to be stably inserted into the first slot 10a and to rotate along its height within the first slot 10a, thereby achieving a hinged connection between the connector 30 and the second component 13, further improving the connection stability and reliability between the connector 30 and the second component 13. Furthermore, the first protrusion 30a can be provided on the sidewall of the second component 13, and the first slot 10a can be provided at the second end of the connector 30. By utilizing the mating insertion of the first protrusion 30a and the first slot, the second component and the connector can be assembled, further improving the structural stability and reliability of the photovoltaic system.

[0050] It should be noted that in some embodiments, such as Figure 4 As shown, the photovoltaic module 10 can have first slots 10a provided on the sidewalls of the first module 11 and the sidewalls of the second module 13. In this case, the first and second ends of the connector 30 can both have first protrusions 30a; or, as shown... Figure 6 As shown, the photovoltaic module 10 can have a first latching protrusion 30a on the sidewall of the frame of the first module 11 and the sidewall of the frame of the second module 13. In this case, the first end and the second end of the connector 30 can both have a first latching groove 10a; or, as shown... Figure 5 As shown, one of the first component 11 and the second component 13 can be provided with a first slot 10a, and the other with a first protrusion 30a. In this case, the first end and the second end of the connector 30 can be provided with matching first protrusions 30a or first slots 10a, respectively. Therefore, there are many ways to rotate and hinge the first component 11 and the second component 13 with the connector 30. Appropriate selection can be made according to the actual installation requirements of the photovoltaic system 100 to achieve a stable hinge connection between the connector 30 and the first component 11 and the second component 13. This allows the photovoltaic module 10 to form a whole under the strong connection of the connector 30, better ensuring the enhancement of the overall structural strength of the photovoltaic module 10 and further improving the overall structural stability and reliability of the photovoltaic system 100.

[0051] See Figure 5 and Figure 6 In one embodiment of this application, a first slot 10a is provided at the first end and / or the second end, and the connector 30 includes a first mounting part 31a and a second mounting part 31b, which are stacked and connected. A first sub-groove is provided on the side of the first mounting part 31a facing the second mounting part 31b, and a second sub-groove is provided on the side of the second mounting part 31b facing the first mounting part 31a. The first sub-groove and the second sub-groove are connected to form the first slot.

[0052] In this embodiment, the connector 30 can be formed by overlapping the separate first mounting part 31a and the second mounting part 31b to form the first slot 10a. At this time, the surface of the first mounting part 31a facing the second mounting part 31b can be provided with an upwardly curved first sub-groove, and the surface of the second mounting part 31b facing the first mounting part 30a can be provided with a downwardly curved second sub-groove. The first sub-groove and the second sub-groove are respectively matched and configured so that the first slot 10a can be formed by the cooperation of the first sub-groove and the second sub-groove, thus ensuring the stable engagement of the first slot 10a and the first protrusion 30a.

[0053] The first mounting portion 31a and the second mounting portion 31b are connected to form the first slot 10a. This allows the first slot 10a to more easily engage with the first protrusion on the photovoltaic module by overlapping, reducing the difficulty of assembling the connector 30 and further improving the ease of assembly and disassembly of the photovoltaic system 100. The first mounting portion 31a and the second mounting portion 31b can be fixedly connected using fasteners 37c such as bolts or screws; or they can be bonded together with adhesive to form a single unit; or they can be tightly bound together with straps to form a single unit. There are many ways to connect and install the first mounting portion 31a and the second mounting portion 31b, and this application does not limit this method.

[0054] Furthermore, it should be noted that in some embodiments, reference is made to... Figure 5 When a first latching protrusion 30a is provided on one of the first end and the second end of the connector 30, and a first latching groove 10a is provided on the other end, the first mounting part 31a or the second mounting part 31b can be provided with the first latching protrusion 30a on one side, and the first mounting part 31a and the second mounting part 31b can be stacked and fitted together, and then connected on the other side by the first sub-groove and the second sub-groove to form the first latching groove 10a, thus ensuring the stable structural design of the connector 30.

[0055] In other embodiments, reference is made to Figure 6When both the first and second ends of the connector 30 are provided with a first slot 10a, the first sub-slots can be provided on both sides of the surface of the first mounting part 31a, and the second sub-slots can be provided on both sides of the surface of the second mounting part 31b, so that the first mounting part 31a and the second mounting part 31b can be stacked and connected to form the first slot 10a at both ends, thus ensuring the stable structural design of the connector 30.

[0056] See Figure 7 and Figure 8 In one embodiment of this application, the connector 30 includes a first connecting structure 35a and a second connecting structure 35b. One end of the first connecting structure 35a is hinged to one end of the second connecting structure 35b. The end of the first connecting structure 35a away from the second connecting structure 35b is hinged to the sidewall of the frame of the first component 11. The end of the second connecting structure 35b away from the first connecting structure 35a is hinged to the sidewall of the frame of the second component 13.

[0057] In this embodiment, the connector 30 can be configured as a split structure. In this case, by making the connector 30 include a first connecting structure 35a and a second connecting structure 35b, one end of the first connecting structure 35a can be hinged to one end of the second connecting structure 35b, so that the connector 30 can form a hinge structure design similar to a hinge, allowing the first connecting structure 35a and the second connecting structure 35b to be rotatably arranged relative to each other in the height direction. Thus, by hinged to the first component 11 at one end of the first connecting structure 35a away from the second connecting structure 35b, and hinged to the second component 13 at one end of the second connecting structure 35b away from the first connecting structure 35a, the width of the connector 30 in the direction of the arrangement of the first component 11 and the second component 13 can be adjusted by the relative rotation of the first connecting structure 35a and the second connecting structure 35b. This allows the connector 30 to be better adjusted to the gap width setting corresponding to the first component 11 and the second component 13, making the connector 30 more suitable for connecting first components 11 and second components 13 with various different spacings. This ensures the overall assembly of the photovoltaic module 10 and further improves the structural stability and reliability of the photovoltaic system 100.

[0058] See Figure 8 and Figure 9 In one embodiment of this application, one end of the first connecting structure 35a is provided with one of the second slot 355 or the second protrusion 351, and one end of the second connecting structure 35b is provided with the other of the second slot 355 or the second protrusion 351, and the second protrusion 351 is rotatably engaged with the second slot 355.

[0059] In this embodiment, the connector 30 can have a second slot 355 at one end of the first connecting structure 35a and a second protrusion 351 at one end of the second connecting structure 35b. By rotating the second protrusion 351 into the second slot 355, the hinge between the first connecting structure 35a and the second connecting structure 35b can be stably achieved, and the first connecting structure 35a and the second connecting structure 35b can rotate relative to each other in the height direction. The width of the connector 30 in the arrangement direction of the first component 11 and the second component 13 can be adjusted so that the connector 30 can connect the first component 11 and the second component 13 more stably, thereby improving the overall structural assembly stability and reliability of the photovoltaic module 10.

[0060] Alternatively, the connector 30 can have a second latching protrusion 351 at one end of the first connecting structure 35a and a second latching groove 355 at one end of the second connecting structure 35b. By rotating the second latching protrusion 351 into the second latching groove 355, the hinge connection between the first connecting structure 35a and the second connecting structure 35b can be stably achieved, allowing the first connecting structure 35a and the second connecting structure 35b to rotate relative to each other in the height direction. The width of the connector 30 in the arrangement direction of the first component 11 and the second component 13 can be adjusted so that the connector 30 can connect the first component 11 and the second component 13 more stably, thereby improving the overall structural assembly stability and reliability of the photovoltaic module 10.

[0061] See Figure 10 , Figure 12 and Figure 13 In one embodiment of this application, one end of the first connecting structure 35a is provided with a first mounting cylinder 353, and one end of the second connecting structure 35b is provided with a second mounting cylinder 357. The first mounting cylinder 353 and the second mounting cylinder 357 are arranged along the same straight line. The connector 30 also includes a rotating shaft 35c, which passes through the first mounting cylinder 353 and the second mounting cylinder 357. The first connecting structure 35a and the second connecting structure 35b can rotate relative to each other around the rotating shaft 35c.

[0062] In this embodiment, the first mounting cylinder 353 and the second mounting cylinder 357 can be hollow cylindrical structures. By arranging the first mounting cylinder 353 of the first connecting structure 35a and the second mounting cylinder 357 of the second connecting structure 35b along the same straight line, the first mounting cylinder 353 and the second mounting cylinder 357 can be connected end to end, and the inner cavity of the first mounting cylinder 353 can be connected to the inner cavity of the second mounting cylinder 357. Then, the rotating shaft 35c can pass through the first mounting cylinder 353 and the second mounting cylinder 357, so that the rotating shaft 35c connects the first connecting structure 35a and the second connecting structure 35b to form a whole, ensuring the overall assembly of the photovoltaic module 10 and further improving the overall structural stability and reliability of the photovoltaic system 100.

[0063] In one embodiment of this application, the two ends of the rotating shaft 35c are respectively connected to limit structures, which are used to restrict the rotating shaft 35c from moving axially.

[0064] In this embodiment, the limiting structure can be multiple bosses connected to the periphery of the end of the rotating shaft 35c, or it can be a block or baffle connected to the end of the rotating shaft 35c. The two ends of the rotating shaft 35c can be respectively set to pass through the first mounting cylinder 353 and the second mounting cylinder 357. By connecting the limiting structure to the exposed end of the rotating shaft 35c, the overall end cross-sectional dimension of the rotating shaft 35c can be larger than the cross-sectional dimensions of the first mounting cylinder 353 and the second mounting cylinder 357. This is beneficial to use the limiting structure to limit the axial movement of the rotating shaft 35c, effectively preventing the rotating shaft 35c from sliding out of the first mounting cylinder 353 and the second mounting cylinder 357 along the axial direction, and ensuring the overall structural stability and reliability of the connector 30.

[0065] In this design, one limiting structure can be integrally formed with one end of the rotating shaft 35c, while the other limiting structure can be detachably connected to the other end of the rotating shaft 35c. This allows the rotating shaft 35c to pass through the first mounting cylinder 353 and the second mounting cylinder 357 before the limiting structure is installed at the end of the rotating shaft 35c, facilitating the installation of the connector 30. Alternatively, the two limiting structures can be detachably connected to both ends of the rotating shaft 35c, facilitating the replacement and adjustment of the rotating shaft 35c, adapting to the assembly of various connectors 30, and further improving the practicality of the connector 30. This application does not limit the connection method between the limiting structure and the rotating shaft 35c, as long as it ensures the stable passage and connection of the rotating shaft 35c through the first mounting cylinder 353 and the second mounting cylinder 357, and utilizes the limiting structure to achieve stable axial limiting of the rotating shaft 35c.

[0066] See Figures 11 to 13 In one embodiment of this application, at least one end of the rotating shaft 35c is provided with a fixing cap 359, the fixing cap 359 is provided with a plurality of limiting blocks 3591, and the plurality of limiting blocks 3591 are arranged at intervals around the rotating shaft 35c; the first connecting structure 35a and the second connecting structure 35b can be inserted between any two adjacent limiting blocks 3591.

[0067] In this embodiment, by providing a fixing cap 359 at at least one end of the rotating shaft 35c, the fixing cap 359 can abut against the sidewalls of the first connecting structure 35a and the second connecting structure 35b to limit the rotating shaft 35c, prevent the rotating shaft 35c from detaching from the first connecting structure 35a and the second connecting structure 35b, and improve the overall structural stability and reliability of the connector 30. At this time, by setting multiple limiting blocks 3591 around the rotating shaft 35c on the side of the fixing cap 359 facing the rotating shaft 35c, the adjacent limiting blocks 3591 can form a snap-fit ​​gap. This is beneficial for the first connecting structure 35a to snap into the snap-fit ​​gap between two adjacent limiting blocks 3591 when the fixing cap 359 abuts against the first connecting structure 35a and the second connecting structure 35b, and for the second connecting structure 35b to snap into the snap-fit ​​gap between two adjacent limiting blocks 3591. This allows the width of the connector 30 to be adjusted by the relative rotation of the first connecting structure 35a and the second connecting structure 35b, and the fixing cap 359 to snap into the first connecting structure 35a and the second connecting structure 35b to fix the overall structure of the connector 30 after the width adjustment. This ensures a stable connection between the connector 30 and the first component 11 and the second component 13, so that the photovoltaic module 10 can form a more stable overall structure, further improving the overall structural stability and reliability of the photovoltaic system 100.

[0068] See Figure 14 and Figure 15 In one embodiment of this application, the connector 30 includes a third connecting structure 37a, a fourth connecting structure 37b, and a fastener 37c. One end of the third connecting structure 37a is hinged to the first component 11, and one end of the fourth connecting structure 37b is hinged to the second component 13. The third connecting structure 37a and the fourth connecting structure 37b are stacked. The third connecting structure 37a is provided with a first mounting hole 371, and the fourth connecting structure 37b is provided with a second mounting hole 373. The fastener 37c passes through the first mounting hole 371 and the second mounting hole 373 and fastens the third connecting structure 37a and the fourth connecting structure 37b.

[0069] In this embodiment, the connector 30 may include a third connecting structure 37a and a fourth connecting structure 37b stacked together. By using fasteners 37c to pass through the first mounting hole 371 and the second mounting hole 373 to connect the third connecting structure 37a and the fourth connecting structure 37b, the third connecting structure 37a and the fourth connecting structure 37b can be hinged and assembled with the first component 11 and the second component 13 respectively, and then the fasteners 37c are used to fasten the third connecting structure 37a and the fourth connecting structure 37b together, thereby realizing the overall assembly of the photovoltaic module 10. The fastener 37c can be a combination of bolt and nut, so that after the bolt passes through the first mounting hole 371 and the second mounting hole 373, the free end of the bolt is connected by the nut, so that the nut and the bolt's nut clamp and fix the third connecting structure 37a and the fourth connecting structure 37b. Of course, the fastener 37c can also be a shuttle-shaped pin or other structure. This application does not limit the structural form of the fastener 37c, as long as it can achieve the fastening assembly of the fastener 37c to the third connecting structure 37a and the fourth connecting structure 37b.

[0070] By employing the cooperative installation method of the third connecting structure 37a, the fourth connecting structure 37b, and the fastener 37c, the connector 30 can adopt a convenient split structure design. This facilitates on-site construction and assembly by first hingedly connecting the third connecting structure 37a with the first component 11 and the fourth connecting structure 37b with the second component 13, thus pre-installing the connector 30 on the photovoltaic module 10. Then, when installing the photovoltaic module 10 on the color steel tile 200 roof, the fastener 37c is used to connect the third connecting structure 37a and the fourth connecting structure 37b. This facilitates a more convenient assembly process between the connector 30 and the photovoltaic module 10, further improving the reliability and assembly convenience of the photovoltaic system 100.

[0071] Furthermore, in one embodiment of this application, at least one of the first mounting hole 371 and the second mounting hole 373 is an elongated hole, which extends along the arrangement direction of the first component 11 and the second component 13.

[0072] By making at least one of the first mounting holes 371 and the second mounting holes 373 an elongated hole structure extending along the arrangement direction of the first component 11 and the second component 13, the third connecting structure 37a and the fourth connecting structure 37b can still be fastened by fasteners 37c passing through the first mounting holes 371 and the second mounting holes 373 even after the third connecting structure 37a and the fourth connecting structure 37b are relatively separated or close to each other by a certain distance. This facilitates the width adjustment of the connector 30 along the arrangement direction of the first component 11 and the second component 13, so that the connector 30 can be better adjusted to the corresponding gap width setting of the first component 11 and the second component 13. This makes the connector 30 more suitable for connecting first components 11 and second components 13 with various different spacings, ensuring the overall assembly of the photovoltaic module 10 and further improving the structural stability and reliability of the photovoltaic system 100.
