Technical Field

[0001] This application relates to the field of photovoltaic technology, and in particular to a method for installing and disassembling photovoltaic modules. Background Technology

[0002] Photovoltaic (PV) components are used to convert received solar energy into electrical energy to meet daily production and usage needs. PV components include photovoltaic modules and mounting brackets for installing these modules onto rooftops. PV modules can replace traditional roof tiles and be used directly as roofing materials, saving on roofing costs and reducing roof load-bearing requirements. However, existing PV modules suffer from inconvenient installation and disassembly, resulting in low efficiency and difficulty in replacement. Summary of the Invention

[0003] This application provides a method for installing and removing photovoltaic modules, which can improve the replacement efficiency of photovoltaic modules.

[0004] The first aspect of this application provides a method for installing a photovoltaic module, wherein the photovoltaic module is installed on a roof using an installation bracket, the photovoltaic module includes a first frame and a second frame, and the installation bracket includes a first limiting part and a second limiting part, wherein the second limiting part includes a limiting rib; The installation method includes: Provide multiple of the aforementioned mounting brackets and multiple of the aforementioned photovoltaic modules; Secure all the mounting brackets to the roof; Take one of the aforementioned photovoltaic modules; The first frame of the photovoltaic module is connected to one of the mounting brackets, so that the first limiting part can restrict the movement of the photovoltaic module in the first direction; The second frame of the photovoltaic module is overlapped with the second limiting part of another mounting bracket adjacent in the second direction, so that the limiting rib can restrict the movement of the photovoltaic module in the second direction; The first direction is perpendicular to the second direction.

[0005] In one possible design, the mounting bracket has a receiving space, and the first frame includes an extended limiting portion; when connecting the first frame of the photovoltaic module to one of the mounting brackets, the installation method specifically includes: extending at least a portion of the first frame into the receiving space, such that the extended limiting portion overlaps with the first limiting portion in the first direction.

[0006] In one possible design, the second limiting portion further includes a body, and the second frame includes an abutting limiting portion; when the second frame of the photovoltaic module is overlapped with the second limiting portion of another mounting bracket adjacent in the second direction, the installation method specifically includes: extending at least a portion of the second frame into the receiving space, such that the second frame is higher than the limiting rib in the first direction; moving the photovoltaic module in the second direction, such that the second frame passes over the limiting rib in the second direction; moving the photovoltaic module in the first direction, such that the second frame overlaps with the body, such that the abutting limiting portion abuts against the limiting rib in the second direction.

[0007] In one possible design, after the second frame of the photovoltaic module is overlapped with the second limiting portion of another mounting bracket adjacent along the second direction, the installation method further includes: sequentially connecting a plurality of photovoltaic modules into a row along a third direction; sequentially installing multiple rows of photovoltaic modules along the second direction; the first direction, the second direction, and the third direction are perpendicular to each other.

[0008] In one possible design, the photovoltaic module further includes a third frame and a fourth frame, the fourth frame including a splicing element; when multiple photovoltaic modules are sequentially connected in a row along a third direction, the installation method specifically includes: The third frame of one of the two adjacent photovoltaic modules along the third direction is overlapped on the splice of the other.

[0009] In one possible design, the photovoltaic module further includes a laminate; when multiple rows of the photovoltaic modules are installed sequentially along the second direction, the installation method specifically includes: overlapping the first frame of one of two adjacent photovoltaic modules along the second direction onto the laminate of the other.

[0010] In the photovoltaic module installation method provided in this application, two adjacent mounting brackets along the second direction are respectively engaged with the first and second frames of the same photovoltaic module, restricting the movement of the photovoltaic module in both directions. This improves the installation stability of the photovoltaic module and enhances its wind resistance. Furthermore, using this installation method, both ends of a single photovoltaic module are connected to the mounting brackets via a limiting engagement, eliminating the need for screws or similar fixing parts. This simplifies the installation process and improves installation efficiency. Consequently, if the photovoltaic module needs replacement or maintenance, a new photovoltaic module can be quickly installed.

[0011] The second aspect of this application provides a method for disassembling a photovoltaic module, wherein the photovoltaic module is installed on the roof by a mounting bracket, the photovoltaic module includes a first frame and a second frame, and the mounting bracket includes a first limiting part and a second limiting part, the second limiting part including a limiting rib; The disassembly method includes: Move the photovoltaic module along the first direction so that the second frame moves away from the second limiting part of the mounting bracket along the first direction; Release the limiting fit between the second frame and the limiting rib so that the photovoltaic module can move along the second direction; Move the photovoltaic module along the second direction to release the limiting engagement between the first frame and the first limiting part of another mounting bracket adjacent to the second direction, so that the photovoltaic module can move along the first direction; Remove the photovoltaic modules from the roof; The first direction is perpendicular to the second direction.

[0012] In one possible design, when releasing the limiting fit between the second frame and the limiting rib, the disassembly method specifically includes: moving the photovoltaic module along the first direction so that the second frame is higher than the limiting rib in the first direction; and moving the photovoltaic module along the second direction so that the second frame passes over the limiting rib in the second direction.

[0013] In one possible design, the first frame includes an extended limiting portion, and the mounting bracket has a receiving space; when the limiting engagement between the first frame and the first limiting portion of another mounting bracket adjacent along the second direction is released, the disassembly method specifically includes: moving the photovoltaic module along the second direction so that the extended limiting portion moves out of the receiving space.

[0014] In one possible design, the photovoltaic module further includes a laminate; before releasing the limiting fit between the second frame and the limiting rib, the disassembly method further includes: lifting one end of another photovoltaic module adjacent to the photovoltaic module along the second direction, which is provided with the first frame, upward along the first direction, so that the first frame of the other photovoltaic module is away from the laminate of the photovoltaic module.

[0015] In one possible design, the photovoltaic module further includes a third frame and a fourth frame, the fourth frame including a splicing piece; before releasing the limiting fit between the second frame and the limiting rib, the disassembly method further includes: lifting one end of another photovoltaic module adjacent to the photovoltaic module along a third direction, which is provided with the third frame, upward along the first direction, so that the third frame of the other photovoltaic module is away from the splicing piece of the photovoltaic module; the first direction, the second direction and the third direction are perpendicular to each other.

[0016] The photovoltaic module disassembly method provided in this application only requires releasing the limiting engagement between the two ends of the photovoltaic module along the second direction and the two mounting brackets to remove it, without removing other fixing parts. This simplifies the disassembly process and improves the efficiency of photovoltaic module disassembly. Furthermore, when using this disassembly method to disassemble a single photovoltaic module within a photovoltaic assembly, it is not necessary to remove other surrounding photovoltaic modules first, further improving the disassembly efficiency of a single photovoltaic module. This facilitates the replacement efficiency of a single photovoltaic module, making maintenance and replacement easier, saving labor and time costs, and preventing damage to other photovoltaic modules during the disassembly process.

[0021] 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.

[0022] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application.

[0023] 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.

[0024] 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, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0025] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0026] This application provides an embodiment of a photovoltaic module installation method, such as... Figure 1As shown, multiple mounting brackets 1 and multiple photovoltaic modules 2 together constitute a photovoltaic component 10. The photovoltaic modules 2 are installed on the roof 20 via the mounting brackets 1. Specifically, the roof 20 is provided with multiple runners 40 extending along the inclined direction of the roof 20 and multiple tile strips 30 perpendicular to the runners 40. The runners 40 are fixed to the roof 20 with steel nails, and the tile strips 30 are also fixed to the runners 40 with steel nails. The mounting brackets 1 are fixed to the tile strips 30 with screws or other fixing parts. The photovoltaic modules 2 are detachably connected to the mounting brackets 1 to install the photovoltaic modules 2 onto the roof. In this structure, the photovoltaic modules 2 can replace some of the original traditional tiles on the roof 20 and be used directly as the building material of the roof 20, which can save the cost of the roof 20 and reduce the load-bearing requirements of the roof 20.

[0027] The structure of photovoltaic module 2 and mounting bracket 1 will be described in detail below: like Figure 2 As shown, the photovoltaic module 2 includes a laminate 23, a first frame 21, and a second frame 22. The first frame 21 and the second frame 22 are installed at both ends of the laminate 23 along the second direction X. The first frame 21 and the second frame 22 can protect the edges of the laminate 23 at both ends along the second direction X. Furthermore, the first frame 21 and the second frame 22 are also used to connect with other components (such as brackets, mounting brackets 1, or purlins) so that the laminate 23 can be fixedly installed on the ground, wall, or roof 20, or other places where it can be exposed to sunlight.

[0028] like Figure 3 and Figure 4 As shown, the first frame 21 has a first mounting groove 212, and the second frame 22 has a second mounting groove 222. The laminate 23 extends into the first mounting groove 212 and the second mounting groove 222 at both ends along the second direction X, respectively. That is, the first frame 21 and the second frame 22 respectively clamp the two ends of the laminate 23 along the second direction X, so that the first frame 21 and the second frame 22 are connected to the three surfaces of the laminate 23, improving the connection stability between the first frame 21 and the second frame 22 and the laminate 23. In this structure, the first frame 21 and the second frame 22 can protect the edges of the laminate 23 at both ends along the second direction X, reducing the possibility of damage to the edges of the laminate 23 by external foreign objects, thereby improving the operational reliability of the laminate 23.

[0029] Adhesive can also be applied to the first mounting groove 212 and the second mounting groove 222 to improve the connection strength between the first frame 21, the second frame 22 and the laminate 23. Furthermore, the adhesive can be bonded to both ends of the laminate 23 along the second direction X. The adhesive can seal the edges of the laminate 23, reducing the possibility of external air and liquid entering the interior of the laminate 23, thereby improving the service life of the laminate 23.

[0030] like Figure 3 and Figure 4 As shown, a first limiting protrusion 214 is provided on the first frame 21, and / or a second limiting protrusion 223 is provided on the second frame 22. The first limiting protrusion 214 is used to abut against the upper surface of a portion of the laminate 23 extending into the first mounting groove 212 to increase the friction between the first frame 21 and the laminate 23, thereby improving the connection strength between the first frame 21 and the photovoltaic module 2. Similarly, the second limiting protrusion 223 is used to abut against the upper surface of a portion of the laminate 23 extending into the second mounting groove 222 to increase the friction between the second frame 22 and the laminate 23, thereby improving the connection strength between the second frame 22 and the photovoltaic module 2.

[0031] The first limiting protrusion 214 and the second limiting protrusion 223 also serve to limit the uncured adhesive coated in the first mounting groove 212 and the second mounting groove 222, respectively. This restricts the uncured adhesive from flowing freely relative to the first frame 21 / second frame 22 or the laminate 23, making it less likely for the uncured adhesive to detach from the first mounting groove 212 and the second mounting groove 222, thereby improving the bonding reliability between the first frame 21 / second frame 22 and the laminate 23. Furthermore, the adhesive is less likely to obscure the portion of the laminate 23 located outside the first mounting groove 212 and the second mounting groove 222, allowing the laminate 23 to have a larger area for solar energy collection, thus increasing the power generation efficiency of the photovoltaic module 2.

[0032] In this application embodiment, the number or shape of the first limiting protrusion 214 and the second limiting protrusion 223 are not limited.

[0033] In addition, such as Figure 3 and Figure 4 As shown, a first bending portion 215 is provided on the first frame 21, and / or a second bending portion 224 is provided on the second frame 22. Both the first bending portion 215 and the second bending portion 224 bend downward along the first direction Z. That is, the first bending portion 215 and the second bending portion 224 can reduce the opening of the first mounting groove 212 and the second mounting groove 222. At the same time, the first bending portion 215 and the second bending portion 224 can abut against the upper surface of the laminate 23, thereby further improving the connection stability between the laminate 23 and the first frame 21 and / or the second frame 22, and preventing the first frame 21 or the second frame 22 from separating from the laminate 23.

[0034] The first bend 215 and the second bend 224 can also be used to limit the uncured adhesive coated in the first mounting groove 212 and the second mounting groove 222, respectively, restricting the uncured adhesive from flowing freely relative to the first frame 21 / second frame 22 or the laminate 23.

[0035] like Figure 5 As shown, along the third direction Y, the two ends of the photovoltaic module 2 are respectively provided with a third frame 26 and a fourth frame 27. The fourth frame 27 includes a frame 271 connected to the laminate 23 and a splicing piece 272 detachably connected to the frame 271.

[0036] Specifically, such as Figure 6 and Figure 7 As shown, the third frame 26 has a third mounting groove 261, and the frame 271 of the fourth frame 27 has a fourth mounting groove 271a. The laminate 23 extends into the third mounting groove 261 and the fourth mounting groove 271a at both ends along the third direction Y, respectively. That is, the third frame 26 and the frame 271 respectively clamp the laminate 23 at both ends along the third direction Y, so that the third frame 26 and the fourth frame 27 are connected to the three surfaces of the laminate 23, improving the connection stability between the third frame 26 and the fourth frame 27 and the laminate 23. With this configuration, the third frame 26 and the fourth frame 27 can protect the edges of the laminate 23 at both ends along the third direction Y, reducing the possibility of damage to the edges of the laminate 23 by external foreign objects, thereby improving the operational reliability of the laminate 23.

[0037] Adhesive can also be applied to the third mounting groove 261 and the fourth mounting groove 271a to improve the connection strength between the third frame 26, the fourth frame 27 and the laminate 23. Furthermore, the adhesive can be bonded to both ends of the laminate 23 along the third Y direction. The adhesive can seal the edges of the laminate 23, reducing the possibility of external air and liquid entering the interior of the laminate 23, thereby improving the service life of the laminate 23.

[0038] like Figure 6 and Figure 7 As shown, a third limiting protrusion 262 is provided on the third frame 26, and / or a fourth limiting protrusion 271b is provided on the frame 271. The third limiting protrusion 262 is used to abut against the upper surface of a portion of the laminate 23 extending into the third mounting groove 261 to increase the friction between the third frame 26 and the laminate 23, thereby improving the connection strength between the third frame 26 and the photovoltaic module 2. Similarly, the fourth limiting protrusion 271b is used to abut against the upper surface of a portion of the laminate 23 extending into the fourth mounting groove 271a to increase the friction between the frame 271 and the laminate 23, thereby improving the connection strength between the frame 271 and the photovoltaic module 2.

[0039] The third limiting protrusion 262 and the fourth limiting protrusion 271b also serve to limit the uncured adhesive coated in the third mounting groove 261 and the fourth mounting groove 271a, respectively. This restricts the uncured adhesive from flowing freely relative to the third frame 26 / fourth frame 27 or the laminate 23, making it less likely for the uncured adhesive to detach from the third mounting groove 261 and the fourth mounting groove 271a, thereby improving the bonding reliability between the third frame 26 / fourth frame 27 and the laminate 23. Furthermore, the adhesive is less likely to obstruct the portion of the laminate 23 located outside the third mounting groove 261 and the fourth mounting groove 271a, allowing the laminate 23 to have a larger area for solar energy collection, thus increasing the power generation efficiency of the photovoltaic module 2.

[0040] In this application embodiment, the number or shape of the third limiting protrusion 262 and the fourth limiting protrusion 271b are not limited.

[0041] like Figure 6 and Figure 7 As shown, a third bend 263 is provided on the third frame 26, and / or a fourth bend 271c is provided on the frame 271. Both the third bend 263 and the fourth bend 271c bend downward along the first direction Z. That is, the third bend 263 and the fourth bend 271c can reduce the opening of the third mounting groove 261 and the fourth mounting groove 271a. At the same time, the third bend 263 and the fourth bend 271c can abut against the upper surface of the laminate 23, thereby further improving the connection stability between the laminate 23 and the third frame 26 and / or the fourth frame 27, and preventing the third frame 26 or the fourth frame 27 from separating from the laminate 23.

[0042] The third bend 263 and the fourth bend 271c can also be used to limit the uncured adhesive coated in the third mounting groove 261 and the fourth mounting groove 271a, respectively, restricting the uncured adhesive from flowing freely relative to the third frame 26 / fourth frame 27 or the laminate 23.

[0043] In addition, such as Figure 6 and Figure 7 As shown, the third frame 26 is also provided with a first raised portion 266 that protrudes toward the third bend 263, and the frame 271 is also provided with a second raised portion 271f that protrudes toward the fourth bend 271c. The first raised portion 266 and the second raised portion 271f can also be used to limit the uncured adhesive coated in the third mounting groove 261 and the fourth mounting groove 271a, respectively, and restrict the uncured adhesive from flowing freely relative to the third frame 26 / fourth frame 27 or the laminate 23.

[0044] like Figure 6 and Figure 7As shown, the frame 271 of the fourth frame 27 is provided with a second snap-fit ​​protrusion 271d and / or a third snap-fit ​​protrusion 271e. The splicing piece 272 of the fourth frame 27 is provided with a second snap-fit ​​portion 272a and / or a third snap-fit ​​portion 272b extending in the third direction Y. The second snap-fit ​​portion 272a can be snapped and fixed with the second snap-fit ​​protrusion 271d, and the third snap-fit ​​portion 272b can be snapped and fixed with the third snap-fit ​​protrusion 271e, so as to connect the splicing piece 272 to the frame 271. Among them, the second snap-fit ​​portion 272a, the third snap-fit ​​portion 272b, the second snap-fit ​​protrusion 271d, and the third snap-fit ​​protrusion 271e can all be provided with guide slopes to facilitate smooth assembly of the frame 271 and the splicing piece 272, thereby improving the assembly efficiency of the photovoltaic module 2.

[0045] like Figure 3 and Figure 4 As shown, the first frame 21 of the photovoltaic module 2 is provided with an extension limiting part 211, and the second frame 22 is provided with an abutment limiting part 221, as shown. Figure 8 As shown, the mounting bracket 1 includes a first limiting part 11 for cooperating with the extension limiting part 211, a second limiting part 12 for cooperating with the abutment limiting part 221, and a connecting part 14 fixedly connected to the first limiting part 11 and the second limiting part 12 along a first direction Z. The second limiting part 12 includes a body 121 and a limiting rib 122 protruding relative to the body 121 along the first direction Z. The first limiting part 11, the second limiting part 12, and the connecting part 14 together form a receiving space 13, which is used to receive at least a portion of the first frame 21 and / or at least a portion of the second frame 22.

[0046] It should be noted that in this application, the second direction X, the first direction Z, and the third direction Y are perpendicular to each other. Specifically, the second direction X can be the width direction of the photovoltaic module 2, the first direction Z can be the thickness direction of the photovoltaic module 2, and the third direction Y can be the length direction of the photovoltaic module.

[0047] As shown in Figures 9(a)-9(d) and Figure 10 As shown, the installation method of photovoltaic module 2 includes the following steps: Step S1: Provide multiple mounting brackets 1 and multiple photovoltaic modules 2.

[0048] like Figure 1 and Figure 11 As shown, multiple photovoltaic modules 2 are arrayed on the roof 20 to form a photovoltaic component 10, which provides sufficient power to users to meet their daily production needs. Each photovoltaic module 2 is connected to at least one mounting bracket 1 at both ends along the first direction to ensure the installation stability of the photovoltaic module 2.

[0049] Step S2: Secure all installed brackets 1 to the roof 20.

[0050] First, fix the mounting bracket 1 to the roof 20 in the preset position, and then install the photovoltaic module 2 uniformly. This way, there will be no obstruction when installing the mounting bracket 1, and the efficiency will be higher. If the mounting bracket 1 is fixed after each row of photovoltaic module 2 is installed, the photovoltaic module 2 will block the roof strip 30 below it, making it inconvenient to fix the mounting bracket 1.

[0051] Specifically, such as Figure 8 As shown, the mounting bracket 1 also includes a side plate 15 fixedly connected to the body 121 and a base plate 16 fixedly connected to the side plate 15. The side plate 15 is used to abut against the batten strip 30 on the roof 20 along the second direction X. The base plate 16 protrudes towards the batten strip 30 along the first direction Z and abuts against the batten strip 30. The body 121 is used to abut against the batten strip 30 on the roof 20 along the first direction Z. The body 121 and / or the side plate 15 are provided with through holes for connecting with fasteners. The mounting bracket 1 is fixed to the batten strip 30 by screws or other fixing parts. That is, the mounting bracket 1 has a C-shaped structure, which can abut against three surfaces of the batten strip 30, increasing the contact area between the mounting bracket 1 and the batten strip 30 and improving the stability of the mounting bracket 1. With the above structure, when installing the hanger 1 on the batten 30, the hanger 1 can be pre-fixed to the batten 30 using a C-shaped structure. After all the hangers 1 are positioned, screws and other fixing parts are then used to fix the hangers 1 to the batten 30. This can improve the installation efficiency of the hangers 1.

[0052] like Figure 24 As shown, in another embodiment, the mounting bracket 1 only has a side plate 15 and no bottom plate 16. The side plate 15 abuts against the tile strips 30 on the roof 20 along the second direction X, and the body 121 abuts against the tile strips 30 on the roof 20 along the first direction Z. The body 121 is fixedly connected to the tile strips 30 by screws or other fixing parts to fix the mounting bracket 1 to the roof 20.

[0053] Step S3: Take one photovoltaic module 2.

[0054] Step S4: Connect the first frame 21 of the photovoltaic module 2 to one of the mounting brackets 1 so that the first limiting part 11 can restrict the photovoltaic module 2 from moving along the first direction Z.

[0055] Step S5: The second frame 22 of the photovoltaic module 2 is attached to the second limiting part 12 of another mounting bracket 1 adjacent to the second direction X, so that the limiting rib 122 can restrict the movement of the photovoltaic module 2 along the second direction X.

[0056] As shown in Figures 9(a) to 9(d), in the above steps, each end of the photovoltaic module 2 along the second direction X needs to be connected to a mounting bracket 1 to ensure that the photovoltaic module 2 cannot move freely in the second direction X and the first direction Z, thereby realizing the installation of the photovoltaic module 2.

[0057] Specifically, the first frame 21 of the photovoltaic module 2 can cooperate with the first limiting part 11 of one of the mounting brackets 1. When the photovoltaic module 2 is blown by the wind, the first limiting part 11 can restrict the photovoltaic module 2 from moving upward along the first direction Z, thereby preventing the photovoltaic module 2 from being lifted or blown away by the wind. The second frame 22 of the photovoltaic module 2 can cooperate with the limiting rib 122 of the adjacent mounting bracket 1. When the photovoltaic module 2 is tilted relative to the roof 20, the limiting rib 122 can prevent the photovoltaic module 2 from sliding downward along the second direction X, thus achieving limiting in both the second direction X and the first direction Z.

[0058] Therefore, in the installation method of the photovoltaic module 2 provided in this application, two adjacent mounting brackets 1 along the second direction X respectively engage with the first frame 21 and the second frame 22 of the same photovoltaic module 2, restricting the movement of the photovoltaic module 2 in the first direction Z and the second direction X. This improves the installation stability of the photovoltaic module 2 and thus enhances its wind resistance. Furthermore, when using the above installation method, both ends of a single photovoltaic module 2 are connected to the mounting brackets 1 through a limiting engagement, eliminating the need for screws or similar fixing parts. This simplifies the installation steps of the photovoltaic module 2, improves installation efficiency, saves parts, and reduces installation costs. Correspondingly, if the photovoltaic module 2 needs replacement or maintenance, a new photovoltaic module 2 can be quickly installed.

[0059] In one specific implementation, for step S4: when connecting the first frame 21 of the photovoltaic module 2 to one of the mounting brackets 1, the installation method specifically includes: extending at least a portion of the first frame 21 into the receiving space 13, so that the extension limiting portion 211 overlaps with the first limiting portion 11 in the first direction Z.

[0060] As shown in Figure 9(b), when there is an overlap between the extended limiting part 211 and the first limiting part 11 in the first direction Z, if the photovoltaic module 2 moves upward in the first direction Z, the extended limiting part 211 will abut against the first limiting part 11. The first limiting part 11 can restrict the photovoltaic module 2 from continuing to move in the first direction Z, thereby limiting the photovoltaic module 2 in the first direction Z.

[0061] In one specific implementation, such as Figure 12As shown, for step S5: when the second frame 22 of the photovoltaic module 2 is overlapped with the second limiting part 12 of another adjacent mounting bracket 1 along the second direction, the installation method specifically includes: Step A1: Extend at least a portion of the second frame 22 into the receiving space 13, so that the second frame 22 is higher than the limiting rib 122 in the first direction Z.

[0062] Step A2: Move the photovoltaic module 2 along the second direction X so that the second frame 22 passes the limiting rib 122 in the second direction X.

[0063] Step A3: Move the photovoltaic module 2 along the first direction Z, and overlap the second frame 22 with the body 121 so that the abutting limit part 221 and the limit rib 122 abut along the second direction X.

[0064] In the above steps, as shown in Figures 9(b) and 9(c), the second frame 22 is positioned higher than the limiting rib 122 in the first direction Z to prevent interference between the second frame 22 and the limiting rib 122 when the photovoltaic module 2 moves in the second direction X. The photovoltaic module 2 first moves in the second direction X, causing the second frame 22 to extend further into the receiving space 13. After the abutting limiting part 221 passes the limiting rib 122 in the second direction X, it moves downward in the first direction Z. This allows the abutting limiting part 221 and the limiting rib 122 to engage in the second direction X. At this time, the limiting rib 122 can restrict the photovoltaic module 2 from sliding downward in the second direction X, thus limiting the photovoltaic module 2 in the second direction X, thereby improving the installation stability of the photovoltaic module 2 and reducing the possibility of the photovoltaic module 2 falling off the roof 20.

[0065] In addition, the second frame 22 overlaps with the main body 121, and the main body 121 can also provide some support for the second frame 22, so that the photovoltaic module 2 can be placed more stably on the roof 20.

[0066] Specifically, such as Figure 8 As shown, specifically, the limiting rib 122 can be inclined towards the inner or outer side of the receiving space 13 along the first direction Z. When the limiting rib 122 is inclined towards the inner side of the receiving space 13 and has an angle of 1° to 7° with the body 121, its limiting effect on the photovoltaic module 2 is optimal. Furthermore, the surface of the limiting rib 122 that abuts against the second frame 22 can also be configured with a serrated structure, which can increase friction and further enhance the limiting effect of the limiting rib 122 on the photovoltaic module 2.

[0067] like Figure 4 and Figure 13As shown, for the photovoltaic module 2 installed according to the above steps, when the photovoltaic module 2 is blown by the wind, the photovoltaic module 2 will lift up along the first direction Z, and the extended limiting part 211 can abut against the first limiting part 11. At this time, the first limiting part 11 can restrict the photovoltaic module 2 from continuing to move along the first direction Z, thereby improving the wind resistance of the photovoltaic module 2.

[0068] Specifically, along the first direction Z, the first limiting portion 11 has a first surface 111 and a second surface 112 disposed opposite to each other. The first surface 111 is used to abut against the laminate 23, and the second surface 112 is used to abut against the extended limiting portion 211.

[0069] When the first frame 21 is connected to the mounting bracket 1 without external force, the first surface 111 can abut against the laminate 23 to provide some support for the photovoltaic module 2, making the photovoltaic module 2 more stable on the roof 20; when the photovoltaic module 2 is blown by the wind and lifted up in the first direction Z, the second surface 112 can abut against the extended limiting part 211 to restrict the photovoltaic module 2 from continuing to move in the first direction Z, thereby improving the wind resistance of the photovoltaic module 2.

[0070] like Figure 4 As shown, along the first direction Z, the first limiting part 11 has a projection on the extended limiting part 211, and the length of the projection along the second direction X is L1, where L1 ≥ 2mm. L1 can specifically be 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm or 6mm, or other values ​​within the above range, which are not limited in this application.

[0071] If the projection length L1 along the second direction X is too small (e.g., less than 2mm), when the photovoltaic module 2 is blown upwards along the first direction Z by the wind, the contact area between the extended limiting part 211 and the second surface 112 will be too small. This results in insufficient limiting ability of the mounting bracket 1 for the photovoltaic module 2, making it easy for the photovoltaic module 2 to be lifted by the wind and separate from the mounting bracket 1 in strong winds, or even fall off the roof 20, posing a significant safety hazard. Therefore, the projection length L1 of the first limiting part 11 on the extended limiting part 211 along the second direction X should be greater than or equal to 2mm to ensure that the limiting effect of the first limiting part 11 on the extended limiting part 211 is optimal, thereby improving the wind resistance of the photovoltaic module 2.

[0072] In addition, buffer elements can be provided on the first surface 111 and / or the second surface 112. On the one hand, when the photovoltaic module 2 moves up and down along the first direction Z, noise may be generated due to collisions between the laminate 23 and the first surface 111, and between the extension limiting part 211 and the second surface 112. The buffer elements can reduce the noise. On the other hand, the mounting bracket 1 is usually made of metal. The buffer elements can prevent hard contact between the photovoltaic module 2 and the metal material, reduce the possibility of damage to the photovoltaic module 2 due to collisions, and help improve the service life of the photovoltaic module 2. Specifically, the buffer elements can be 3M tape or other elastic materials.

[0073] In one specific implementation, such as Figure 10 As shown, after step S5, the installation method further includes: Step S6: Connect multiple photovoltaic modules 2 sequentially into a row along the third direction Y.

[0074] Step S7: Install multiple rows of photovoltaic modules 2 sequentially along the second direction X.

[0075] like Figure 1 and Figure 11 As shown, multiple photovoltaic modules 2 are installed on the roof 20. Multiple photovoltaic modules 2 connected along the third direction Y are called a row, and multiple rows of photovoltaic modules 2 are located along the second direction X. Since the roof 20 is typically sloping, when installing multiple rows of photovoltaic modules 2, they can be installed row by row from bottom to top along the second direction X, with at least a portion of the upper photovoltaic modules 2 overlapping the lower photovoltaic modules 2. If they are installed from top to bottom along the second direction X, the upper photovoltaic modules 2 need to be lifted upwards when installing the lower photovoltaic modules 2.

[0076] In one specific implementation, for step S6: when connecting multiple photovoltaic modules 2 sequentially into a row along the third direction Y, the installation method specifically includes: overlapping the third frame 26 of one of two adjacent photovoltaic modules 2 along the third direction Y onto the splicing piece 272 of the other.

[0077] like Figure 11 and Figure 14As shown, multiple photovoltaic modules 2 are interconnected along a third direction Y via a third frame 26 and a fourth frame 27 to form a row. The splicing component 272 also has a first support portion 272c. When two photovoltaic modules 2 are connected along the third direction Y, the third frame 26 of one photovoltaic module 2 can overlap the first support portion 272c of the other photovoltaic module 2. This connection method has the advantages of rapid assembly and disassembly. At this time, the splicing component 272 can fill the gap between two adjacent photovoltaic modules 2 to form a waterproof structure, preventing rainwater from seeping into the house. The splicing component 272 has a high degree of versatility in assembly, adapting to various connection structures to meet diverse user connection needs.

[0078] Specifically, such as Figure 14 As shown, rainwater can flow along the splicing member 272 to the first water guide channel 273, and be discharged onto the surface of the lower-positioned photovoltaic module 2 through the guidance of the first water guide channel 273. Alternatively, rainwater can flow along the splicing member 272 to the second water guide channel 264, and be discharged onto the surface of the lower-positioned photovoltaic module 2 through the guidance of the second water guide channel 264. Alternatively, rainwater can also flow along the splicing member 272 to the third water guide channel 265, and be discharged onto the surface of the lower-positioned photovoltaic module 2 through the guidance of the third water guide channel 265. The first water guide channel 273 and the second water guide channel 264 can also simplify the structure of the fourth frame 27 and the third frame 26, respectively, to reduce the weight of the third frame 26 and the fourth frame 27.

[0079] like Figure 7 and Figure 14 As shown, at least a portion of the second snap-fit ​​portion 272a is located within the first water channel 273. With this configuration, the structural compactness between the frame 271 and the splicing component 272 is high, meaning the fourth frame 27 occupies less space. Given the limited area of ​​the roof 20, a larger laminate 23 can be installed, resulting in higher power generation efficiency. Furthermore, the splicing component 272 is also provided with a first raised portion 272d. On one hand, the first raised portion 272d can restrict the third frame 26 of the adjacent photovoltaic module 2 along the third direction Y. On the other hand, the first raised portion 272d can also cooperate with the first support portion 272c to prevent rainwater in the third water channel 265 from leaking into the roof wall, thus forming a three-level waterproof structure between the third frame 26 of the photovoltaic module 2 and the fourth frame 27 of the adjacent photovoltaic module 2, improving the waterproof performance of the photovoltaic component 10.

[0080] Because the size of photovoltaic module 2 sometimes cannot perfectly match the size of roof 20, therefore, Figure 11 As shown, tiles 50 can be connected to the side of the photovoltaic module 2 near the edge of the roof 20 along the third direction Y. Specifically, as Figure 15As shown, the third frame 26 can be connected to the tile 50 via the first edge-binding member 28. The first edge-binding member 28 has a Z-shaped overall structure, with a fourth snap-fit ​​portion 281 extending along the third direction Y and a support extension portion 282. The fourth snap-fit ​​portion 281 and the support extension portion 282 can clamp the tile 50 along the first direction Z, so that the first edge-binding member 28 is fixedly connected to the tile 50. The dimension of the support extension portion 282 in the third direction Y is larger than the dimension of the fourth snap-fit ​​portion 281 in the third direction Y. This arrangement makes the structure of the first edge-binding member 28 more stable and can reliably support and clamp the bottom of the tile 50. The first edge-binding member 28 has a high degree of versatility in assembly. The first edge-binding member 28 is adaptable to various connection structures to meet various connection needs of users.

[0081] like Figure 15 As shown, the first edge banding 28 is also provided with a second support portion 283. When the photovoltaic module 2 is connected to the tile 50, the third frame 26 can be supported by the second support portion 283. This connection method has the advantages of quick assembly and quick disassembly. At this time, rainwater can flow along the first edge banding 28 to the second water guide channel 264, and be discharged to the surface of the photovoltaic module 2 at a lower position through the guidance of the second water guide channel 264. Alternatively, rainwater can flow along the first edge banding 28 to the fourth water guide channel 285, and be discharged to the surface of the photovoltaic module 2 at a lower position through the guidance of the fourth water guide channel 285.

[0082] like Figure 15 As shown, the first edge-sealing component 28 is also provided with a second raised portion 284. On the one hand, the second raised portion 284 can restrict the third frame 26 of the adjacent photovoltaic module 2 along the third direction Y. On the other hand, the second raised portion 284 can also cooperate with the second support portion 283 to prevent rainwater in the fourth water channel 285 from leaking to the roof wall, so that the first edge-sealing component 28 and the third frame 26 of the adjacent photovoltaic module 2 form a three-level waterproof structure, which improves the waterproof performance of the photovoltaic component 10.

[0083] like Figure 15 As shown, the first edge-sealing member 28 is also provided with an overlapping portion 286, which is used to overlap the top of the tile 50. With this configuration, the connection between the first edge-sealing member 28 and the tile 50 includes not only clamping but also overlapping, resulting in a greater number of connection points and reducing the possibility of the tile 50 being damaged by the force applied by the first edge-sealing member 28. The overlapping portion 286 can be bonded and fixed to the top of the tile 50, for example, by applying a fluid adhesive between the overlapping portion 286 and the tile 50, which then cures. The overlapping portion 286 may also be provided with a bending portion and a limiting protrusion to restrict the uncured adhesive from flowing freely relative to the overlapping portion 286 or the tile 50, thereby improving the reliability of the bond between the overlapping portion 286 and the tile 50.

[0084] like Figure 16 As shown, the fourth frame 27 can be connected to the tile 50 via the second edge-mounting member 29. The second edge-mounting member 29 is provided with a fifth mounting groove 291, and at least a portion of the tile 50 extends into the fifth mounting groove 291 to achieve a fixed connection between the tile 50 and the second edge-mounting member 29. Specifically, when the photovoltaic module 2 is connected to the tile 50, the second edge-mounting member 29 can be supported on the first support portion 272c of the splicing member 272 of the fourth frame 27. This connection method has the advantages of quick assembly and quick disassembly. At this time, rainwater can flow along the splicing member 272 to the first water guide channel 273 and be discharged to the surface of the photovoltaic module 2 at a lower position through the guidance of the first water guide channel 273. Alternatively, rainwater can also flow along the splicing member 272 to the third water guide channel 265 and be discharged to the surface of the photovoltaic module 2 at a lower position through the guidance of the third water guide channel 265. The first raised portion 272d can cooperate with the first support portion 272c to prevent rainwater in the third water channel 265 from leaking to the roof wall, so that the second edge piece 29 and the fourth frame 27 of the adjacent photovoltaic module 2 form a secondary waterproof structure, which improves the waterproof performance of the photovoltaic component 10.

[0085] In one specific implementation, for step S7: when installing multiple rows of photovoltaic modules 2 sequentially along the second direction X, the installation method specifically includes: overlapping the first frame 21 of one of two adjacent photovoltaic modules 2 along the second direction X onto the laminate 23 of the other.

[0086] like Figure 1 and Figure 8 As shown, the first frame 21 of the upper photovoltaic module 2 is overlapped on the laminate 23 of the lower photovoltaic module 2, so that rainwater can flow downward along the second direction X through the surface of the multiple overlapping laminates 23, thus achieving the effect of guiding rainwater.

[0087] Specifically, such as Figure 2 As shown, a sealing strip 24 is provided on the first frame 21. Along the first direction Z, one end of the sealing strip 24 is fixed to the first frame 21, and the other end is used to abut against the laminate 23. Figure 8As shown, in two adjacent photovoltaic modules 2 along the second direction X, the sealing strip 24 of the upper photovoltaic module 2 can abut against the laminate 23 of the lower photovoltaic module 2 to achieve a sealing and waterproof function. During rain, rainwater can flow along the sealing strip 24 of the upper photovoltaic module 2 to the surface of the lower photovoltaic module 2, preventing it from flowing into the house. Furthermore, when the sealing strip 24 abuts against the lower photovoltaic module 2, it also provides some wind protection, preventing wind from blowing into the gap between the two photovoltaic modules 2 and causing the upper photovoltaic module 2 to lift. At least a portion of the sealing strip 24 is flexible; in this configuration, the sealing strip 24 can act as a buffer, cushioning the interaction force between the lower laminate 23 and the upper connector 25, reducing the possibility of damage to the lower laminate 23.

[0088] Specifically, such as Figure 2 and Figure 17 As shown, the sealing strip 24 can be detachably connected to the first frame 21 via the connector 25. The connector 25 is provided with a mating groove 251, and the sealing strip 24 can slide into the mating groove 251 along the third direction Y, thereby connecting with the connector 25. Figure 5 and Figure 7 As shown, a first snap-fit ​​protrusion 213 is provided on the first frame 21, and a first snap-fit ​​portion 252 extending along the second direction X is provided on the connector 25. The connector 25 and the first frame 21 are snapped and fixed by the first snap-fit ​​portion 252 and the first snap-fit ​​protrusion 213.

[0089] It should be noted that, as Figure 1 As shown, although the roof 20 is inclined relative to the ground, there is an angle of 4.3° between the second direction X and the inclined direction of the roof 20. That is, the photovoltaic module 2 is installed at an incline relative to the roof 20, and each photovoltaic module 2 maintains the same incline angle. This ensures that the multiple photovoltaic modules 2 arranged along the second direction X can be stably connected to each other, ensuring that the photovoltaic components have good water-conducting effect.

[0090] When installing multiple photovoltaic modules 2 using the installation method provided in this application, such as Figure 8 As shown, two photovoltaic modules 2, overlapping each other along the second direction X, are connected to the same mounting bracket 1. At least a portion of the first frame 21 of the upper photovoltaic module 2 and at least a portion of the second frame 22 of the lower photovoltaic module 2 can be accommodated together within the accommodating space 13 of the mounting bracket 1. The first limiting portion 11 of the mounting bracket 1 is used to abut against the laminate 23 of the upper photovoltaic module 2, or to limit the first frame 21 of the upper photovoltaic module 2; the second limiting portion 12 of the mounting bracket 1 is used to abut against and limit the second frame 22 of the lower photovoltaic module 2.

[0091] like Figure 8 As shown, when two adjacent photovoltaic modules 2 are connected along the second direction X, the upper photovoltaic module 2 overlaps with the lower photovoltaic module 2. The laminate 23 of the upper photovoltaic module 2 abuts against the first surface 111 of the first limiting part 11 of the mounting bracket 1. Along the first direction Z, the height difference between the extending limiting part 211 and the second surface 112 is H1, where H1 ≥ 0.5 mm. H1 can specifically be 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, or 5 mm, or other values ​​within the above range. This embodiment does not limit this value.

[0092] The extension limiting part 211 and the second surface 112 have a height difference, which means that after the first frame 21 of the photovoltaic module 2 is connected to the mounting bracket 1, the photovoltaic module 2 can still be raised a certain height along the first direction Z. In this way, when two photovoltaic modules 2 are connected to the same mounting bracket 1, it is only necessary to raise the upper photovoltaic module 2 a little to provide upward space for the lower photovoltaic module 2 so that it can be released from the limiting engagement with the second limiting part 12. It is no longer necessary to remove the upper photovoltaic module 2 to remove the lower photovoltaic module 2, which facilitates the removal and replacement of individual photovoltaic modules 2.

[0093] If the height difference H1 between the extended limiting part 211 and the second surface 112 is less than 0.5mm, under the restriction of the first limiting part 11, the space for the end of the photovoltaic module 2 with the first frame 21 to be lifted upward along the first direction Z is small. This will result in insufficient space for the photovoltaic module 2 connected to the same mounting bracket 1 below it to be lifted upward along the first direction Z. The second frame 22 cannot be released from the limiting rib 122, making it inconvenient to disassemble the photovoltaic module 2 located below. Therefore, when the height difference H1 between the extended limiting part 211 and the second surface 112 is greater than or equal to 0.5mm, it is convenient to install and disassemble the photovoltaic module 2 without causing the photovoltaic module 2 to be blown away by the wind and fall off the mounting bracket 1.

[0094] like Figure 8As shown, the connecting portion 14 bends away from the receiving space 13 along the second direction X. When two adjacent photovoltaic modules 2 along the second direction X are received in the same receiving space 13 of the mounting bracket 1, the connecting portion 14 can also abut against the first frame 21 and / or the second frame 22 to restrict the movement of the photovoltaic module 2 along the second direction X. During the installation and use of the photovoltaic module 2, the first limiting portion 11 will be subjected to an upward or downward force along the first direction Z (for example, when the photovoltaic module 2 is lifted, the first frame 21 abuts against the first limiting portion 11, or the laminate 23 overlaps on the first limiting portion 11 and applies pressure to the first limiting portion 11). At this time, the upper half of the bent structure can deform synchronously with the first limiting portion 11 without causing the second limiting portion 12 to deform, thus improving the stability of the mounting bracket 1. Similarly, when the lower half of the bent structure deforms synchronously with the second limiting portion 12, it will not cause the first limiting portion 11 to deform. Furthermore, when the connecting part 14 is a bent structure, it provides a certain deformation allowance, making the connecting part 14 less likely to be damaged or broken due to deformation under force, which is beneficial to improving the service life of the mounting bracket 1.

[0095] In addition, to ensure the installation stability of photovoltaic module 2, one or two mounting brackets 1 are connected to both sides of photovoltaic module 2 along the third direction Y. Specifically, as shown... Figure 18 As shown, when a mounting bracket 1 is connected to each side of the photovoltaic module 2 along the third direction Y, the length of the mounting bracket 1 along the third direction is L2, where 60mm ≤ L2 ≤ 80mm. Specifically, L2 can be 60mm, 62mm, 65mm, 68mm, 70mm, 71mm, 73mm, 75mm, 77mm, 79mm, or 80mm, or other values ​​within the above range. This embodiment does not impose any restrictions on this value.

[0096] When L2 is too small (e.g., less than 60mm), the contact area between the mounting bracket 1 and the photovoltaic module 2 is small, which reduces the limiting effect of the mounting bracket 1 on the photovoltaic module 2, making the photovoltaic module 2 prone to detachment. When L2 is too large (e.g., greater than 80mm), it will result in an excessively large volume and weight of the mounting bracket 1, increasing costs and raising the difficulty of manufacturing and installation. Therefore, when the length L2 of the mounting bracket 1 along the third direction is 60mm to 80mm, it can ensure the installation stability of the photovoltaic module 2, prevent the photovoltaic module 2 from detaching from the mounting bracket 1, and also appropriately reduce the total cost of the photovoltaic component 10.

[0097] Because the four corners of photovoltaic module 2 are relatively fragile, the corner positions should be avoided when connecting mounting bracket 1 to photovoltaic module 2. Figure 18As shown, when a mounting bracket 1 is connected to each side of the photovoltaic module 2 along the third direction Y, the distance between the edge of the mounting bracket 1 and the end of the photovoltaic module 2 along the third direction Y is L3, where 150mm≤L3≤400mm. L3 can specifically be 150mm, 160mm, 180mm, 200mm, 230mm, 250mm, 270mm, 290mm, 300mm, 310mm, 320mm, 340mm, 350mm, 380mm, or 400mm, or other values ​​within the above range; this embodiment does not impose any restrictions on this.

[0098] When the distance L3 between the edge of the mounting bracket 1 and the end of the photovoltaic module 2 is 150mm~400mm, it ensures that the mounting bracket 1 and the photovoltaic module 2 are connected at the middle part along the third direction Y, ensuring the installation stability of the photovoltaic module 2 and preventing the photovoltaic module 2 from swaying due to instability. It also ensures that the mounting bracket 1 is far away from the corners of the photovoltaic module 2 along the third direction Y, preventing damage to the corners of the photovoltaic module 2 due to stress concentration. This ensures the installation stability of the photovoltaic module 2 while reducing the possibility of damage.

[0099] like Figure 19 As shown, when two mounting brackets 1 are connected to both sides of the photovoltaic module 2 along the third direction Y, the length of the mounting bracket 1 along the third direction Y is L4, 40mm≤L4≤80mm. L4 can specifically be 40mm, 45mm, 48mm, 50mm, 55mm, 60mm, 63mm, 67mm, 70mm, 72mm, 76mm or 80mm, or other values ​​within the above range. This embodiment does not limit this value.

[0100] When L4 is too small, the contact area between the mounting bracket 1 and the photovoltaic module 2 is small, which reduces the limiting effect of the mounting bracket 1 on the photovoltaic module 2, making the photovoltaic module 2 prone to detachment. When L4 is too large, it will result in an excessively large size and weight of the mounting bracket 1, increasing costs. Moreover, an excessively large size will make it difficult to install the photovoltaic module 2 onto the mounting bracket 1. Therefore, the length L4 of the mounting bracket 1 along the third direction should be 40mm to 80mm. This application preferably uses a mounting bracket 1 with L4 of 60mm, which can maximize the installation stability of the photovoltaic module 2, prevent the photovoltaic module 2 from detaching from the mounting bracket 1, and also appropriately reduce the total cost of the photovoltaic component 10.

[0101] Because the four corners of photovoltaic module 2 are relatively fragile, the corner positions should be avoided when connecting mounting bracket 1 to photovoltaic module 2. Figure 19As shown, when two mounting brackets 1 are connected to both sides of the photovoltaic module 2 along the third direction Y, the distance between the edge of the mounting bracket 1 and the end of the photovoltaic module 2 along the third direction Y is L5, where 150mm≤L5≤300mm. Specifically, L5 can be 150mm, 160mm, 180mm, 200mm, 210mm, 230mm, 250mm, 260mm, 290mm, or 300mm.

[0102] When L5 is too small (e.g., less than 150mm), the distance between the mounting bracket 1 and the corner of the photovoltaic module 2 is too small, and the corner of the photovoltaic module 2 is at risk of breaking. When L5 is too large (e.g., greater than 300mm), it means that the distance between the two mounting brackets 1 in the third direction Y is too small, which will lead to insufficient installation stability of the photovoltaic module 2, and the photovoltaic module 2 is prone to shaking along both sides of the third direction Y. When the distance L5 between the edge of the mounting bracket 1 and the end of the photovoltaic module 2 is 150mm~300mm, it can ensure the installation stability of the photovoltaic module 2 and avoid shaking of the photovoltaic module 2; it can also ensure that the mounting bracket 1 is far away from the corner of the photovoltaic module 2 in the third direction Y, preventing the corner of the photovoltaic module 2 from being damaged due to stress concentration.

[0103] As shown in Figures 20(a)-20(e) and Figure 21 As shown, the disassembly method for photovoltaic module 2 includes the following steps: Step B1: Move the photovoltaic module 2 along the first direction Z so that the second frame 22 moves away from the second limiting part 12 of the mounting bracket 1 along the first direction Z.

[0104] Step B2: Release the limiting fit between the second frame 22 and the limiting rib 122 so that the photovoltaic module 2 can move along the second direction X.

[0105] Step B3: Move the photovoltaic module 2 along the second direction X, release the limiting engagement between the first frame 21 and the first limiting part 11 of another mounting bracket 1 adjacent along the second direction X, so that the photovoltaic module 2 can move along the first direction Z.

[0106] Step B4: Remove the photovoltaic module 2 from the roof 20.

[0107] In the above steps, since the photovoltaic module 2 is connected to a mounting bracket 1 at both ends along the second direction X, it is necessary to detach both ends from these two mounting brackets 1 to disassemble the photovoltaic module 2. As shown in Figures 20(c) and 20(d), firstly, move the second frame 22 away from the second limiting part 12 along the first direction Z to ensure that the second frame 22 no longer overlaps with the body 121 of the second limiting part 12. Then, release the limiting fit between the second frame 22 and the limiting rib 122, so that the end of the photovoltaic module 2 with the second frame 22 is disconnected from the mounting bracket 1, and the photovoltaic module 2 can move freely in the second direction X. Then, move the photovoltaic module 2 along the second direction X to release the limiting fit between the first frame 21 and the other mounting bracket 1, so that the end of the photovoltaic module 2 with the first frame 21 is disconnected from the mounting bracket 1, and the photovoltaic module 2 can also move freely in the first direction Z. At this point, the movement of the photovoltaic module 2 as a whole is no longer restricted, and it can be removed from the roof 20, thus achieving disassembly.

[0108] The method for disassembling the photovoltaic module 2 provided in this application only requires releasing the limiting engagement between the two ends of the photovoltaic module 2 along the second direction X and the two mounting brackets 1, without removing other fixing parts. This simplifies the disassembly steps of the photovoltaic module 2 and improves the disassembly efficiency. Furthermore, when using this disassembly method to disassemble a single photovoltaic module 2 in the photovoltaic component 10, it is not necessary to remove other surrounding photovoltaic modules 2 first, further improving the disassembly efficiency of a single photovoltaic module 2. This facilitates the replacement efficiency of a single photovoltaic module 2, makes maintenance and replacement of the photovoltaic module 2 more convenient, saves labor and time costs, and avoids damage to other photovoltaic modules 2 during the disassembly process.

[0109] In one specific implementation, for step B2: when releasing the limiting fit between the second frame 22 and the limiting rib 122, the disassembly method specifically includes: C1: Move the photovoltaic module 2 along the first direction Z so that the second frame 22 is higher than the limiting rib 122 in the first direction Z.

[0110] C2: Move the photovoltaic module 2 along the second direction X so that the second frame 22 passes the limiting rib 122 in the first direction Z.

[0111] like Figure 8 As shown, since the limiting rib 122 abuts against the abutting limiting part 221 of the second frame 22 in the second direction X, it is necessary to first lift the photovoltaic module 2 upward along the first direction Z so that the abutting limiting part 221 moves away from the limiting rib 122. In this way, when the photovoltaic module 2 is moved along the second direction X, the limiting rib 122 will not interfere with the abutting limiting part 221, and the limiting fit between the second frame 22 and the limiting rib 122 can be released.

[0112] In one specific implementation, for step B3: when releasing the limiting engagement between the first frame 21 and the first limiting part 11 of another mounting bracket 1 adjacent along the second direction X, the disassembly method specifically includes: moving the photovoltaic module 2 along the second direction X so that the extended limiting part 211 is moved out of the accommodating space 13.

[0113] As shown in Figure 20(d), when the extended limiting part 211 moves out of the accommodating space 13, the extended limiting part 211 and the first limiting part 11 no longer overlap in the first direction Z, which can release the limiting cooperation between the first frame 21 and the first limiting part 11 of another mounting bracket 1 adjacent in the second direction X, so that the photovoltaic module 2 can move in the first direction Z.

[0114] It should be noted that since the first frame 21 and the second frame 22 of the same photovoltaic module 2 are respectively housed in the housing space 13 of different mounting brackets 1, it is necessary to ensure that the second frame 22 is also moved out of the housing space 13 of the mounting bracket 1 to which it is connected, so that the photovoltaic module 2 can move freely in the first direction Z. Otherwise, the first limiting part 11 of the mounting bracket 1 will interfere with the second frame.

[0115] In one specific implementation, for step B2: before releasing the limiting fit between the second frame 22 and the limiting rib 122, the disassembly method further includes: lifting one end of another photovoltaic module 2 adjacent to the photovoltaic module 2 along the second direction X, which is provided with the first frame 21, upward along the first direction Z, so that the first frame 21 of the other photovoltaic module 2 is away from the laminate 23 of the photovoltaic module 2.

[0116] Specifically, such as Figure 1 As shown, two adjacent photovoltaic modules 2 along the second direction X overlap each other and are connected to the same mounting bracket 1. Therefore, if it is necessary to remove the lower photovoltaic module 2, the upper photovoltaic module 2 needs to be lifted upward along the first direction Z so that its first frame 21 is away from the laminate 23 of the lower photovoltaic module 2, thereby providing space for the lower photovoltaic module 2 to be lifted upward along the first direction Z so that the lower photovoltaic module 2 can be released from the limiting rib 122.

[0117] In one specific implementation, for step B2: before releasing the limiting fit between the second frame 22 and the limiting rib 122, the disassembly method further includes: lifting one end of another photovoltaic module 2 adjacent to the photovoltaic module 2 along the third direction Y, which is provided with a third frame 26, upward along the first direction Z, so that the third frame 26 of the other photovoltaic module 2 is away from the splicing piece 272 of the photovoltaic module.

[0118] Since the third frame 26 and fourth frame 27 of two adjacent photovoltaic modules 2 along the third direction Y overlap each other, when disassembling photovoltaic module 2, it is necessary to lift the adjacent photovoltaic module 2 upward along the first direction Z so that the third frame 26 of the adjacent photovoltaic module 2 is away from the third frame 26 of the photovoltaic module 2 to be disassembled, thereby providing space for the photovoltaic module 2 to be disassembled to be lifted upward along the first direction Z so that the photovoltaic module 2 to be disassembled can release the limiting rib 122 from the limiting engagement.

[0119] It should be noted that after the abutting and limiting part 221 of the photovoltaic module 2 to be disassembled separates from the limiting rib 122, the photovoltaic module 2 adjacent to it along the third direction Y can be lowered. The photovoltaic module 2 to be disassembled does not need to remain in an upward state. It can be lowered and then moved and pulled out along the second direction X to achieve the disassembly of the photovoltaic module 2. However, the photovoltaic module 2 located above along the second direction X remains in an upward state until the photovoltaic module 2 to be disassembled moves away from the photovoltaic module 2 located above it along the second direction X.

[0120] As shown in Figures 23(a)-23(d), when replacing a new photovoltaic module 2, the method is the same as the installation method of the photovoltaic module 2. However, it is necessary to first lift the photovoltaic module 2 adjacent to the third direction Y and the photovoltaic module 2 adjacent to the second direction X upward along the first direction Z. Then, as shown in Figures 23(a) and 23(b), install the extension limiting part 211 of the first frame 21 of the new photovoltaic module 2 into the receiving space 13 of the mounting bracket 1, so that the first limiting part 11 of the mounting bracket 1 has a projection on the extension limiting part 211 of the first frame 21. Then, extend the second frame 22 of the photovoltaic module 2 into the receiving space 13 of another mounting bracket 1 located above along the second direction X. Move the photovoltaic module 2 along the first direction Z so that the second frame 22 is higher than the limiting rib 122 on the second limiting part 12 of the mounting bracket 1 in the first direction Z. Continue to move the photovoltaic module 2 along the second direction X so that the first limiting part 12 is higher than the limiting rib 122 on the second limiting part 12 of the mounting bracket 1. 1. The projection on the extension limiting part 211 increases in length L1 along the second direction X; as shown in Figures 23(b) and 23(c), first lower the rear end of the new photovoltaic module 2 so that the abutting limiting part 221 of the second frame 22 abuts against the limiting rib 122 of the third row mounting bracket 1, and then lower the front end of the new photovoltaic module 2 so that its sealing strip 24 abuts against the laminate 23 of the first row photovoltaic module 2; as shown in Figure 23(d), after the first frame 21 and the second frame 22 of the new photovoltaic module 2 are connected to the mounting brackets 1 below and above respectively, the photovoltaic module 2 adjacent along the second direction X and the photovoltaic module 2 adjacent along the third direction Y are lowered so that the third frame 26 of the photovoltaic module 2 adjacent along the third direction Y is connected to the splicing piece 272 of the new photovoltaic module 2, and the sealing strip 24 of the third row photovoltaic module 2 abuts against the laminate 23 of the new photovoltaic module 2. Thus, the replacement of the photovoltaic module 2 can be realized.
