Description

Technical Field

[0001] The present application relates to the photovoltaic field, and in particular to a photovoltaic module installation structure, a photovoltaic component and a roof photovoltaic system. Background Art

[0002] Photovoltaic power generation is a power generation technology that directly converts solar energy into electrical energy. The main device for photovoltaic power generation is the photovoltaic module used to obtain solar radiation energy. Simply put, photovoltaic modules are installed in application places such as the outer surface of the building's envelope structure to form a power generation array to obtain electricity.

[0003] The installation of traditional photovoltaic modules usually adopts the method of bolts and pressure blocks, in which the photovoltaic modules are fixed to the photovoltaic support by passing the bolts through the screw holes and cooperating with the pressure blocks; this installation method is time-consuming and labor-intensive, the disassembly and assembly process is cumbersome, the efficiency is low, and more materials and labor are required; therefore, the existing design of photovoltaic modules adopts plug-in installation to overcome this technical problem, but the successful implementation of the plug-in method in the prior art has high requirements for installation. If the installer plugs in the wrong position or orientation, repeated adjustments may be required, or even cause the connection to fail.

[0004] Therefore, this application is filed. Utility Model Content

[0005] In response to the above-mentioned technical problems, the purpose of this application is to reduce the number of bolts required by optimizing the installation structure, achieve quick disassembly and assembly, improve work efficiency, and further reduce the difficulty of disassembly and assembly when photovoltaic components adopt a plug-in solution, making the operation simpler and improving the fault tolerance rate; thereby, a photovoltaic component installation structure, photovoltaic components and roof photovoltaic system are proposed.

[0006] In a first aspect of the present application, a mounting structure of a photovoltaic assembly is provided, which includes a mounting rail, a photovoltaic support and a stop structure; the mounting rail includes a mounting groove; the photovoltaic support includes a plug-in portion, at least a portion of the plug-in portion is configured to be accommodated in the mounting groove and connected to the mounting rail; the stop structure includes a first stop body, the first stop body is disposed in the mounting groove and connected to the mounting rail; and the first stop body can allow the mounting rail to slide relative to the plug-in portion in the positive direction of its length direction, and stop the plug-in portion in the reverse direction of the length direction.

[0007] In a further scheme of the present application, the first stop body is rotatably connected to the mounting rail; when the mounting rail slides relative to the plug-in part in the positive direction along its length direction, the first stop body rotates so that the plug-in part passes through the first stop body; the first stop body is configured to reset after the plug-in part passes through the first stop body, so as to abut against one end of the plug-in part in the reverse direction of the length direction.

[0008] Based on this solution, when the first stop body arranged in the installation groove contacts one end of the plug-in part, the first stop body can rotate under the mutual contact force, thereby avoiding the plug-in part so that the plug-in part passes through the first stop body; after the plug-in part passes through the first stop body, the first stop body is reset under the action of gravity or elastic force to stop the plug-in part from the reverse direction; this avoids the steps of manually adjusting or removing the stop body in the traditional design, simplifies the installation process, improves installation efficiency, and avoids the problem of the plug-in part not being able to be installed correctly due to operational errors.

[0009] In a further solution of the present application, when the mounting rail slides relative to the plug-in portion in the opposite direction of its length direction, the first stopper abuts against the plug-in portion.

[0010] In a further solution of the present application, when the plug-in portion is received in the mounting groove, a gap h is provided between the plug-in portion and the inner wall of the mounting groove in the height direction of the mounting guide rail to reserve an escape space for the first stopper to rotate.

[0011] In an optional scheme of the present application, the first stop body includes a limiting portion, a baffle portion and a connecting portion; the limiting portion extends in the length direction, the baffle portion is connected to one end of the limiting portion and extends in the height direction, and the baffle portion can at least partially abut against the plug-in portion in the height direction; the connecting portion protrudes in the width direction at the connection between the limiting portion and the baffle portion and is rotatably connected to the mounting guide rail; the limiting portion and the inner walls of the mounting groove can abut against each other so that the first stop body abuts against the plug-in portion in the opposite direction of the length direction.

[0012] Based on this solution, when the baffle portion of the first stopper contacts one end of the plug-in portion, the baffle portion drives the entire first stopper to rotate axially along the connecting portion under the mutual contact force with the plug-in portion, thereby avoiding the plug-in portion so that the plug-in portion passes through the first stopper; after the plug-in portion passes through the first stopper, the first stopper is reset to the initial state under the action of gravity, and the limiting portion and the inner wall of the installation groove abut against each other, thereby limiting the first stopper from rotating in the reverse direction. Through the setting of the reset mechanism and the limiting portion, the first stopper can firmly maintain its position after installation, thereby enhancing the stability of the entire structure. At the same time, the first stopper has the advantages of simple structure and reduced processing and manufacturing costs.

[0013] In a further solution of the present application, the mounting rail includes a base plate and two side walls that are spaced apart and extend in the height direction, the base plate and the side walls together form a mounting groove; the side wall is provided with a first buckle that protrudes in the width direction, and the plug-in portion is provided with a second buckle that corresponds to the first buckle; the second buckle is mutually engaged with the first buckle when the plug-in portion is received in the mounting groove to constrain the mounting rail and the photovoltaic support. Based on this solution, the stable connection between the mounting rail and the photovoltaic support can be ensured by mutually engaging, while avoiding the use of traditional fixing methods such as screws or welding, thereby simplifying the installation process, reducing the difficulty of installation and improving the efficiency of installation.

[0014] In a further solution of the present application, the first clip protrudes from the side wall in the installation groove; or the first clip protrudes from the side wall outside the installation groove.

[0015] In a further embodiment of the present application, the mounting groove includes a first opening and a second opening, the first opening is arranged at the end of the mounting rail along the length direction, and the second opening is arranged on the side of the mounting rail along the height direction facing the plug-in portion; wherein the plug-in portion can be plugged into the mounting groove from the first opening along the length direction, or can be plugged into the mounting groove from the second opening along the height direction.

[0016] Based on this solution, the setting of the first opening and the second opening allows the installation guide rail to be plugged into the plug-in part along the length direction; and when there are many obstacles on the roof and the installation space is relatively tight, it is also possible to choose to connect to the plug-in part in the form of buckling in the height direction. By adapting to the above method of multi-directional installation, the constraints of the on-site environment on the installers can be reduced, the requirements for accuracy can be reduced, unnecessary adjustments and repositioning can be reduced, and the possibility of installation errors can be reduced, thereby improving installation efficiency.

[0017] In a further solution of the present application, the first buckle includes a first guide surface, and the second buckle includes a second guide surface; compressive stress is applied to the plug-in part through the installation groove in the height direction, and the side wall is deformed by the mutual squeezing of the first guide surface and the second guide surface, so that the plug-in part can extend into the installation groove and the first buckle and the second buckle are engaged with each other.

[0018] The second aspect of the present application also provides a photovoltaic component, including a photovoltaic module and the above mounting structure; wherein, there are multiple mounting rails and they are installed on the backlight surface of the photovoltaic module, and each mounting rail corresponds to at least one photovoltaic support, and the photovoltaic module is connected to the photovoltaic support via the mounting rail.

[0022] 1. Compared with the traditional bolt connection or welding embodiment, the connection is simpler. The installer only needs to connect the installation slot to the corresponding plug-in part of the photovoltaic support to complete the assembly, which can improve the installation efficiency of the entire photovoltaic module, and no screw connection is required to reduce the use of corresponding tools;

[0023] 2. The design of the first stopper can greatly improve the efficiency of installation and achieve quick installation.

[0065] like Figure 1 and Figure 2 As shown, in an illustrative embodiment of the mounting structure 100 provided by the present invention, the mounting structure 100 includes a mounting rail 10 and a photovoltaic support 20 .

[0066] Among them, the mounting rail 10 is used to connect the photovoltaic module 200, which is extended in a straight line and connected to the backlight surface of the photovoltaic module 200. The side of the mounting rail 10 away from the photovoltaic module 200 includes a mounting groove 11 with an opening; the photovoltaic support 20 is used to be connected to the roof panel, including a plug-in portion 21 corresponding to the mounting groove 11, and the plug-in portion 21 protrudes in the direction of the mounting groove 11. The mounting rail 10 is directly connected to the plug-in portion 21 of the photovoltaic support 20 through the mounting groove 11 to achieve the positioning and installation of the photovoltaic module 200; compared with the traditional bolt connection or welding embodiment, the connection is simpler. The installer only needs to connect the mounting groove 11 to the corresponding plug-in portion 21 of the photovoltaic support 20 to complete the assembly, which can improve the installation efficiency of the entire photovoltaic module, and no screw connection is required to reduce the use of tools; at the same time, the snap-on form is easier to disassemble and reinstall, which is convenient for maintenance and replacement of photovoltaic modules.

[0067] Furthermore, when the mounting rail 10 and the photovoltaic support 20 are installed, at least a portion of the plug-in portion 21 along the height direction H of the mounting rail 10 is accommodated in the mounting groove 11 and connected to the mounting rail 10 .

[0068] For the convenience of description, the length direction L mentioned in the context of this application refers to the installation rail 10 and its extension direction, which can be referred to as Figure 1 , while the width direction W and the height direction H refer to two directions that are horizontally perpendicular and vertically perpendicular to the length direction L respectively; those skilled in the art should understand that the orientation or position relationship shown in the drawings is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0069] Based on the clamping mode of the installation groove 11 and the plug-in portion 21, the installation structure 100 further includes a stop structure, which is arranged in the installation groove 11 and connected to the installation guide rail 10, and the stop structure is arranged to be able to abut against the plug-in portion 21 in the length direction L of the installation guide rail 10.

[0070] It can be understood that when the mounting rail 10 and the photovoltaic support 20 are snapped together, the mounting rail 10 can also slide relative to the photovoltaic support 20 in the length direction. On the one hand, the stop structure is used to constrain the degree of freedom in the length direction to ensure the stable connection of the plug-in part 21 in the mounting groove 11. On the other hand, it can also play a positioning role so that the photovoltaic component can be installed in a fixed position.

[0071] Based on the above, the embodiment of the utility model proposes a general inventive concept, that is, the stop structure includes a first stop body 31, and the first stop body 31 is connected to the mounting groove 11; the first stop body 31 is configured to allow the plug-in portion 21 to pass through the first stop body 31 in the positive direction of the length direction L, and to stop one end of the plug-in portion 21 in the reverse direction of the length direction L. Specifically, the first stop body 31 can allow the mounting rail 10 to slide relative to the photovoltaic support 20 along the positive direction of its length direction L, and stop the plug-in portion 21 in the reverse direction to position and restrict the movement of the mounting rail 10.

[0072] It is understandable that when the photovoltaic assembly is in a stable installation state, the photovoltaic assembly as a whole is usually relatively tilted to better receive light, and the first stopper 31 is used to maintain a stable connection between the mounting rail 10 and the photovoltaic support 20, to prevent the photovoltaic assembly from accidentally sliding or falling off in the tilt direction under its own gravity or external force, so as to improve the reliability and stability of the connection. Since the photovoltaic support 20 is fixed in position, the movement of the mounting rail 10 relative to the photovoltaic support 20 is used as a reference in this application, that is, the direction in which the mounting rail 10 slides downward in the tilt direction is defined as "reverse", and the opposite direction is defined as "forward"; combined with the above, the first stopper 31 can make the mounting rail 10 be resisted in the direction of tilting and sliding, and slide freely in the direction away from the tilting and sliding.

[0073] Of course, the concepts of positive and reverse directions proposed above are merely descriptive concepts, which means that the definition of direction is mainly for the convenience of describing and explaining the working principle of the first stopper 31, rather than an absolute direction in the physical sense.

[0074] The forward and reverse design of the first stop portion 31 can greatly improve the efficiency of installation. No matter whether the installer connects the mounting rail 10 to the plug-in portion 21 in the forward or reverse direction, the first stop portion 31 can be used to quickly constrain the freedom in the length direction and position the photovoltaic components in the same position, thereby reducing the required installation time and cost. At the same time, when the photovoltaic components need to be maintained or replaced, only force needs to be applied to move the photovoltaic support 20 in the forward direction to disengage it from the mounting rail 10, and the entire photovoltaic component can be disassembled, thereby reducing the difficulty of disassembly.

[0075] Furthermore, the mounting groove 11 completely penetrates the entire mounting rail 10 in the length direction L, so that it includes a first opening 111 and a second opening 112, the first opening 111 is arranged at the end of the mounting rail 10 along the length direction L, and the second opening 112 is arranged on the side of the mounting rail 10 facing the plug-in portion 21 in the height direction H; wherein the plug-in portion 21 can be plugged into the mounting groove 11 from the first opening 111 along the length direction L, or plugged into the mounting groove 11 from the second opening 112 along the height direction H.

[0076] Based on the above, an embodiment of the utility model provides a preferred solution, that is, the first stop body 31 is rotatably connected to the mounting rail 10, and the first stop body 31 is configured as follows: when the mounting rail 10 slides relative to the plug-in portion 21 in the positive direction along its length direction, the first stop body 31 rotates to allow the plug-in portion 21 to pass through the first stop body 31; after the plug-in portion 21 passes through the first stop body 31, the first stop body 31 can be reset to abut against one end of the plug-in portion 21 in the reverse direction of the length direction.

[0077] like Figure 3 , the mounting rail 10 on the photovoltaic module is plugged into the photovoltaic support 20 in the positive direction of the length direction L. At this time, the plug-in portion 21 enters the mounting groove 11 from the first opening 111 at one positive end of the mounting rail 10, that is, the mounting rail 10 slides relative to the plug-in portion 21 in the positive direction of its length direction. When the first stopper 31 provided in the mounting groove 11 contacts one end of the plug-in portion 21, the first stopper 31 can rotate under the mutual contact force, thereby avoiding the plug-in portion 21 so that the plug-in portion 21 passes through the first stopper 31; after the plug-in portion 21 passes through the first stopper 31, the first stopper 31 is reset under the action of gravity or elastic force to stop the plug-in portion 21 from the reverse direction, forming a structure as shown in FIG. Figure 1 The secure installation state is shown.

[0078] like Figure 4 In another embodiment of the utility model, the mounting rail 10 on the photovoltaic module can be plugged into the photovoltaic support 20 in the reverse direction of the length direction L. At this time, the plug-in portion 21 enters the mounting groove 11 from the first opening 111 at the reverse end of the mounting rail 10, that is, the mounting rail 10 can slide relative to the plug-in portion 21 in the reverse direction of its length direction under the action of gravity and / or thrust. When the first stopper 31 provided in the mounting groove 11 contacts one end of the plug-in portion 21, the first stopper 31 is configured to stop the plug-in portion 21 in the reverse direction, forming a stopper 31 as shown in FIG. Figure 1 The secure installation state is shown.

[0079] It is understandable that no matter whether the mounting rail 10 is plugged into the photovoltaic support 20 in the forward or reverse direction along the length direction L, the difficulty of installation is greatly reduced. For example, the installer only needs to slide the mounting rail 10 toward the photovoltaic support 20 in the forward or reverse direction, and the best result can be as follows: Figure 1 of a stable installation.

[0080] like Figure 5Based on the above design, when there are many obstacles on the roof and the installation space is relatively tight, the mounting rail 10 on the photovoltaic module can also be directly buckled on the photovoltaic support 20 along the height direction H. At this time, the plug-in portion 21 enters the mounting groove 11 from the second opening 112 of the mounting rail 10 to form a snap connection. Then, according to the buckled position, the mounting rail 10 slides relative to the photovoltaic support 20 in the forward or reverse direction along the length direction, thereby finally forming the following Figure 1 The secure installation state is shown.

[0081] By adapting to the above-mentioned multi-directional installation method, the constraints of the on-site environment on the installer can be reduced, the requirements for accuracy can be reduced, the installation process can be made simpler, unnecessary adjustments and repositioning can be reduced, and the possibility of installation errors can be reduced, thereby improving the installation efficiency. At the same time, compared with the traditional block-type connection that requires screws for fixing, the installation structure 100 provided by the embodiment of the utility model reduces the use of screws, which can reduce the time for installation and maintenance, thereby improving work efficiency.

[0082] like Figure 6 Since the first stopper 31 needs to rotate along the axis inside the installation groove 11, when the plug-in portion 21 is received in the installation groove 11, a gap h is provided between the plug-in portion 21 and the installation groove 11 in the height direction, and the gap h is to reserve enough avoidance space for the first stopper 31 to rotate, so as to ensure that the first stopper 31 can rotate smoothly here.

[0083] In some feasible embodiments, the stop structure further includes a second stop body (not shown), which can be a stopper such as a latch or a screw, and is configured to abut against the other end of the plug-in portion 21 in the length direction L of the mounting rail 10, thereby constraining the mounting rail 10 in both the forward and reverse directions. It can be understood that in some application scenarios, the mounting rail 10 can be assembled with the photovoltaic support 20 and then directly integrated with the roof panel. In order to ensure that it does not fall off during transportation, the freedom of movement of the mounting rail 10 can be limited on both sides along the length direction.

[0084] In a specific embodiment of the present utility model, the first stopper 31 is provided as Figure 7 As shown, the first stop structure 31 includes a limiting portion 311, a baffle portion 312 and a connecting portion 313; the limiting portion 311 extends along the length direction L, the baffle portion 312 is connected to one end of the limiting portion 311 and extends along the height direction H, and the baffle portion 312 can at least partially abut against the plug-in portion 21 in the height direction H; the connecting portion 313 protrudes from the connection between the limiting portion 311 and the baffle portion 312 along the width direction W and is rotatably connected to the mounting guide rail 10; the limiting portion 311 and the inner walls of the mounting groove 11 can abut against each other, so that the first stop body 31 abuts against the plug-in portion 21 in the opposite direction of the length direction L.

[0085] Specifically, Figures 8a to 8c As an example, the mounting rail 10 on the photovoltaic module is inserted into the photovoltaic support 20 in the positive direction of the length direction L, that is, the mounting rail 10 slides relative to the plug-in portion 21 in the positive direction of its length direction. When the baffle portion 312 of the first stopper 31 contacts one end of the plug-in portion 21, the baffle portion 312 drives the entire first stopper 31 to rotate axially along the connecting portion 313 under the mutual contact force with the plug-in portion 21 (such as Figure 8b ), thereby avoiding the plug-in portion 21, so that the plug-in portion 21 passes through the first stopper 31; after the plug-in portion 21 passes through the first stopper 31, the first stopper 31 is reset to the position as shown in the figure below under the action of gravity. Figure 8c In the initial state, the limiting portion 311 and the inner wall of the installation groove 11 abut against each other, thereby limiting the first stopper 31 from rotating in the reverse direction, so as to stop the plug-in portion 21 from the reverse direction to form a stable installation state.

[0086] like Fig. 9 As a modified example of the embodiment of the utility model, the first stopper 31 includes an elastic member 311', a baffle portion 312 and a connecting portion 313; the baffle portion 312 extends in the height direction and is rotatably connected to the mounting rail 10 through the connecting portion 313; the elastic member 311' is connected to the connecting portion 313, wherein the elastic member 311' extends an end portion 3111, and the end portion 3111 abuts against the baffle portion 313 to restrict the rotation angle of the baffle portion 313, so that the baffle portion 313 can only rotate in the positive direction, and the elastic member 311' can rotate in the positive direction. The elastic member 311' is configured to have a rebound force in the reverse rotation so that the first stop body 31 can be rotated and reset. Specifically, when the mounting rail 10 slides relative to the plug-in portion 21 in the positive direction along its length direction, the baffle portion 312 overcomes the elastic force of the elastic member 311' under the mutual contact force with the plug-in portion 21, so that the baffle portion 312 rotates to avoid the plug-in portion 21. After the plug-in portion 21 passes through the first stop body 31, the first stop body 31 is reset under the action of the rebound force of the elastic member 311 to stop the plug-in portion 21.

[0087] like Fig.10 The mounting rail 10 includes a base plate 12 and two side walls 13 arranged at intervals and extending in the height direction H. The base plate 12 and the side walls 13 together form a mounting groove 11; the side wall 13 is provided with a first buckle 14 protruding in the width direction W, and the plug-in portion 21 is provided with a second buckle 22 corresponding to the first buckle 14; the second buckle 22 is mutually engaged with the first buckle 14 when the plug-in portion 21 is received in the mounting groove 11 to constrain the mounting rail 10 and the photovoltaic support 20. The mutually engaged manner can ensure a stable connection between the mounting rail 10 and the photovoltaic support 20, avoiding the use of traditional fixing methods such as screws or welding, thereby simplifying the installation process, reducing the difficulty of installation and improving the efficiency of installation.

[0088] In an optional manner, the first buckle 14 can be arranged to protrude from the side wall 13 in the mounting groove 11, such as Fig.11a As shown, or the first buckle 14 protrudes outside the mounting groove 11 and is arranged on the side wall 13, as shown Fig.11b As shown, the specific settings can be adaptively adjusted according to the needs.

[0089] It can be understood that when the first clip 14 protrudes in the mounting groove 11, the first clip 14 and the second clip 15 are hidden inside the mounting groove 11, which can make the overall structure more compact, reduce the overall width of the photovoltaic support 20, and be more suitable for installation scenarios with limited space. And because the clip structure is inside, it is not easily affected by external factors, and can prevent external objects or debris from mistakenly entering the clip and causing failure, thereby improving its stability. On the contrary, when the first clip 14 is located outside the mounting groove 11, the installer can see its mating position more intuitively, so that it is more convenient to perform installation and fixing operations to simplify the installation process, and it is easier to check the state and integrity of the clip fit, which is convenient for maintenance and inspection.

[0090] In a preferred solution, the first buckle 14 protrudes from the inner side of the mounting groove 11 and is arranged obliquely toward the substrate 12 , and the second buckle 22 is arranged obliquely in a direction away from the substrate 12 .

[0091] Further Fig.12 , the first buckle 14 includes a first guide surface 141 and a first holding surface 142, and the second buckle 22 includes a second guide surface 221 and a second holding surface 222; Figure 4 As shown, in the height direction H, compressive stress is applied to the plug-in portion 21 through the mounting groove 11, and the side wall 13 is deformed by mutual squeezing of the first guide surface 141 and the second guide surface 221, so that the plug-in portion 21 can be inserted into the mounting groove 11 and the first buckle 14 and the second buckle 22 are mutually buckled. The design of the first guide surface 141 and the second guide surface 221 enables the plug-in portion 21 to be automatically locked with the mounting groove 11, which simplifies the installation process compared to traditional fixing methods such as screws or welding, reduces the technical requirements for the installer, and improves the installation efficiency.

[0092] like Figures 13a to 13c, align the installation rail 10 with the plug-in part 21 of the photovoltaic support 20, and lower it in the height direction H. After the first clip 14 and the second clip 22 come into contact, the installer applies compressive stress to the plug-in part 21 by pressing down appropriately. At this time, the first guide surface 141 and the second guide surface 221 squeeze each other, causing the side wall 13 to deform under the force of squeezing, and the opening size of the installation groove 11 is relatively increased, thereby guiding the plug-in part 21 to smoothly enter the installation groove 11; while applying compressive stress, the plug-in part 21 slowly extends into the installation groove 11 until the first clip 14 and the second clip 22 come into contact with each other and snap together. Through the simple step of applying compressive stress, the plug-in part 21 and the installation groove 11 can be quickly and accurately fixed, greatly improving the installation efficiency, and reducing materials such as bolts, nuts and blocks.

[0093] like Fig.14 (The mounting structure in the figure is arranged on the backlight surface of the photovoltaic component 200, and for the sake of convenience, the mounting structure in the schematic diagram is a perspective effect), Embodiment 2 of the present utility model also provides a photovoltaic component 300, including a photovoltaic component 200 and the mounting structure 100 as above; wherein, in the photovoltaic component 300, a plurality of mounting rails 10 are connected to the backlight surface of a photovoltaic component 200, each mounting rail 10 and corresponding to at least one photovoltaic support 20, and the photovoltaic component 200 is connected to the photovoltaic support 20 via the mounting rail 10.

[0094] Specifically, in the photovoltaic component 300 provided in the second embodiment, the mounting rail 10 does not exceed the boundary of the photovoltaic assembly 200 along the length direction L, that is, the length of the mounting rail 10 is relatively short and does not exceed the length or width of the photovoltaic assembly 200. In this way, it can be ensured that the mounting rail 10 is hidden in the backlight surface of the photovoltaic assembly 200, thereby improving the overall aesthetics.

[0095] Furthermore, by pre-installing a plurality of mounting rails 10 on the backlight surface of the photovoltaic module 200, after the photovoltaic support 20 is installed at the application site, the pre-installed mounting rails 10 can be used to quickly and accurately complete the connection between the photovoltaic module 200 and the photovoltaic support 20, thereby simplifying the installation process, improving the installation efficiency, and ensuring the accuracy and reliability of the installation. The mounting rails 10 can be directly pre-installed with the photovoltaic module 200 in the factory to form a prefabricated part, thereby simplifying the process required for on-site installation, so that the on-site staff only needs to plug the photovoltaic module 200 equipped with the mounting rails 10 into the photovoltaic support 20, reducing the difficulty of installation and improving product consistency.

[0096] like Fig.15The third embodiment of the present invention also provides another photovoltaic component 300, including: the mounting structure 100 as described above; a plurality of photovoltaic modules 200; wherein each mounting rail 10 is configured to be a through-length shape, and each mounting rail 10 is connected to a plurality of photovoltaic modules 200.

[0097] During the installation process, the photovoltaic support 20 is first installed at the application site, and then the mounting rail 10 is plugged into the multiple photovoltaic supports 20 for fixing. This design simplifies the installation process, improves the installation efficiency, and ensures the stability and reliability of the photovoltaic modules 200. Next, the photovoltaic modules 200 are built on the mounting rails 10 in sequence. Since each mounting rail 10 is through-length, one mounting rail 10 can connect multiple photovoltaic modules 200, and multiple photovoltaic modules 200 are arranged in sequence along the extension direction of the mounting rail 10. Gaps are left between the photovoltaic modules 200 to reserve heat dissipation channels, which also facilitates daily maintenance of the photovoltaic modules 200 to ensure their long-term stable operation.

[0098] like Fig.16 The embodiment of the utility model also provides a roof photovoltaic system 1000, which includes a roof panel 400 and a plurality of photovoltaic components 300 as provided in the second embodiment. The photovoltaic support 20 is connected to the roof panel 400, and the photovoltaic support 20 is reasonably arranged on the roof panel 400 so that the photovoltaic components 200 are arranged in sequence, and gaps are left between the photovoltaic components 200.

[0099] It can be understood that the photovoltaic support 20 is first installed on the roof panel 400, and after the photovoltaic module 200 and the mounting rail 10 are connected in the factory, the photovoltaic module 200 equipped with the mounting rail 10 is directly plugged into the photovoltaic support 20, so that the photovoltaic module 200 can be installed on the roof panel 400.

[0100] In addition, the embodiment of the present invention also provides a roof photovoltaic system 1000, and the roof photovoltaic system 1000 includes the photovoltaic component 300 and the roof panel 400 provided in the third embodiment.

[0101] Similarly, the photovoltaic support 20 is first installed on the roof panel 400, and then the through-length mounting rail 10 is inserted into multiple photovoltaic supports 20 for fixation, and then multiple photovoltaic modules 200 are sequentially built on the mounting rail 10 at intervals, so that the photovoltaic modules 200 can be installed on the roof panel 400.

[0102] The various technical features described above can be combined arbitrarily. Although all possible combinations of these technical features are not described, any combination of these technical features should be considered to be covered by this specification as long as there is no contradiction in such combination.

[0103] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still adjust the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these adjustments or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
