Description

[0002] In a photovoltaic system, an inverter is responsible for converting the direct current generated by a photovoltaic panel into alternating current, and directly performing energy management at the module level, thereby improving the overall efficiency and flexibility of the system. In some cases, in order to ensure the performance of a photovoltaic array, the inverter is compactly arranged below the photovoltaic panel and connected to the support system of the photovoltaic panel through a mounting assembly. Specifically, one end of the inverter is hung on the support frame of the photovoltaic panel through the mounting assembly, and the inverter dissipates heat through heat dissipation fins.

Detailed implementation manners

[0040] To make the above - mentioned objects, features, and advantages of the present disclosure more obvious and understandable, the following detailed description of the specific embodiments of the present disclosure will be given with reference to the accompanying drawings.

[0041] In the description of the present disclosure, it should be noted that, unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above - mentioned terms in the present disclosure can be understood according to specific situations.

[0042] In the description of this specification, the descriptions referring to terms such as "embodiment", "one embodiment", "some embodiments", "exemplarily", and "one embodiment" mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or embodiment are included in at least one embodiment or embodiment of the present disclosure. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or embodiment. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or embodiments.

[0043] The terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" can explicitly or implicitly include at least one of such features.

[0044] In the drawings, the Z-axis represents the vertical direction, that is, the up and down position, and the positive direction of the Z-axis (that is, the direction pointed by the arrow of the Z-axis) represents up, and the negative direction of the Z-axis represents down; in the drawings, the Y-axis represents the horizontal direction and is specified as the left and right position, and the positive direction of the Y-axis (that is, the direction pointed by the arrow of the Y-axis) represents the right side, and the negative direction of the Y-axis represents the left side; at the same time, it should be noted that the above-mentioned meanings represented by the Z-axis and Y-axis are only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present disclosure.

[0045] In a photovoltaic system, the inverter is responsible for converting the direct current generated by the photovoltaic panel 5 into alternating current, and directly performing energy management at the module level, thereby improving the overall efficiency and flexibility of the system. In some cases, in order to ensure the performance of the photovoltaic array, the inverter is compactly arranged below the photovoltaic panel 5 and is connected to the support system of the photovoltaic panel 5 through a mounting component. Specifically, one end of the inverter is hung on the support frame of the photovoltaic panel 5 through the mounting component, and the inverter forms a cantilever structure, and it dissipates heat through the heat dissipation fins 31.

[0046] However, in this setting method, the end of the inverter without the mounting component is prone to sagging or displacement under the action of gravity or wind (this phenomenon is often referred to as "bowing"). This phenomenon not only causes additional stress concentration on the mounting component itself at one end of the inverter, increasing the risk of fatigue damage, but also makes the inverter have dynamic instability, and this dynamic instability may also affect the working efficiency of the inverter. In the long run, it is more likely to damage the internal electronic components and reduce the service life and service reliability of the equipment.

[0047] Such as Figure 1 and Figure 2As shown, in a first aspect, the present disclosure provides a mounting assembly, including a first connection structure 1 and a second connection structure 2;

[0048] The second connection structure 2 is used to connect to a set end of the power unit 3 to fix the position of the set end;

[0049] The first connection structure 1 has a first end 1a and a second end 1b that are oppositely arranged. The first end 1a is used to connect to the heat dissipation fin 31 of the power unit 3, and the second end 1b is used for fixed setting. Moreover, the position where the first end 1a of the first connection structure 1 is connected to the heat dissipation fin 31 is spaced from the set end.

[0050] Specifically, the power unit 3 has power devices inside and is provided with heat dissipation fins 31. When the power devices inside it work, heat is generated due to energy consumption, and heat dissipation is carried out through the heat dissipation fins 31 to ensure the performance of the power unit 3. On this basis, the specific structure of the power unit 3 is not limited.

[0051] In the following of this specification, the power unit 3 will be taken as an inverter with heat dissipation fins 31 as an example to illustrate the content of the present disclosure.

[0052] It should be understood that both the first connection structure 1 and the second connection structure 2 can be set to one or more according to needs, which is not limited.

[0053] The specific structure of the second connection structure 2 is not limited, as long as it can fix the position of the set end of the power unit 3. For example, it can realize the connection between the set end of the inverter and the photovoltaic mounting frame 4.

[0054] As Figure 2 shown, exemplarily, the photovoltaic mounting frame 4 includes a vertical frame 41, a horizontal frame 42, and a connecting frame 43. The lower end of the vertical frame 41 is supported on, for example, the roof 6 of a house. The horizontal frame 42 extends in a direction perpendicular to the Z-axis and the Y-axis. The horizontal frames 42 are connected by the connecting frame 43. The photovoltaic panels 5 (or photovoltaic modules) are laid on the horizontally spaced horizontal frames 42. The photovoltaic panels 5 can also be connected to the connecting frame 43. The spacing between the horizontal frames 42 is usually greater than the maximum size of the power unit 3. Thus, if the power unit 3 is only connected to the photovoltaic mounting frame 4 through, for example, one of the horizontal frames 42, a cantilever structure may be formed, and the stability of the power unit 3 is weak.

[0055] Referring to Figure 3 , the set end of the power unit 3 has a connecting plate with through holes provided thereon. The second connection structure 2 passes through the through holes and is connected to the horizontal frame 42. The mounting assembly of the present disclosure has the first connection structure 1 and the second connection structure 2, which can avoid forming a cantilever structure and enhance the position stability of the power unit 3.

[0056] Accordingly, the specific structure of the first connection structure 1 is not limited as long as it can be connected to the heat dissipation fins 31 of the power unit 3 and fix the heat dissipation fins 31. An exemplary description will be given later.

[0057] The setting end of the power unit 3 can be set according to requirements, which is not limited. Exemplarily, the power unit 3 has a length direction (corresponding to the U-axis direction in the figure), a width direction (corresponding to the V-axis direction in the figure), and a thickness direction (corresponding to the W-axis direction in the figure). The dimensions of the power unit 3 gradually decrease in the length direction, width direction, and thickness direction. The large surface of the power unit 3 is perpendicular to the thickness direction. The setting end of the power unit 3 is usually one end in the length direction, one end in the width direction, or one end in the thickness direction of the power unit 3. Figure 1 and Figure 2 The situation where the setting end of the power unit 3 is one end along its length direction is shown.

[0058] In this embodiment, the second connection structure 2 of the mounting assembly is connected to the setting end of the power unit 3, which can fix the position of the setting end of the power unit 3. For example, it can realize the connection between the setting end of the inverter and the photovoltaic mounting frame 4. At the same time, the first end 1a of the first connection structure 1 of the mounting assembly is connected to the heat dissipation fins 31 of the power unit 3, the second end 1b of the first connection structure 1 is fixedly arranged, and the position where the first end 1a of the first connection structure 1 is connected to the heat dissipation fins 31 is spaced from the setting end. Thus, the inverter has multiple connection stress points, avoiding the situation that the inverter has only one end with a connection structure and forms a cantilever structure, thereby enhancing the installation reliability and use stability of the inverter.

[0059] In addition, the first end 1a of the first connection structure 1 is connected to the heat dissipation fins 31 instead of other positions. For example, it is not connected to the side plate corresponding to the heat dissipation fins 31 of the inverter. On the one hand, it can avoid occupying the available space of the side plate due to the arrangement of the first connection structure 1, which is beneficial to avoiding restricting the arrangement position and area of the heat dissipation fins 31 on the side plate and ensuring the heat dissipation requirements of the inverter. On the other hand, there is no need to set a structure for connecting with the first connection structure 1 in the area covered by the heat dissipation fins 31 on the side plate, which also facilitates the connection between the first connection structure 1 and the inverter. The structure is simple and has strong practicability.

[0060] Optionally, the first end 1a and the second end 1b of the first connection structure 1 are configured to be relatively position adjustable in at least one direction.

[0061] In this way, the relative position between the first end 1a and the second end 1b of the first connection structure 1 can be adjusted to meet the fixing requirements of the power unit 3.

[0062] Such as Figure 2 、5 As shown in FIG. 6, optionally, the first connection structure 1 includes a first connector 11 and a second connector 12. The first connector 11 and the second connector 12 are movably connected. The first end 1a of the first connection structure 1 is located at one end of the first connector 11 away from the second connector 12, and the second end 1b of the first connection structure 1 is located at one end of the second connector 12 away from the first connector 11.

[0063] In this specification, taking the heat dissipation fin 31 corresponding to the lower side plate of the power unit 3, the upper end of the first connection structure 1 being the first end 1a, and the lower end being the second end 1b as an example for illustration.

[0064] Exemplarily, the upper end of the first connector 11 is connected to the heat dissipation fin 31 of the power unit 3, and the lower end of the second connector 12 is for fixed setting. For example, the lower end of the second connector 12 is connected to the photovoltaic mounting rack 4, or the lower end of the second connector 12 is connected to a structure for supporting the photovoltaic mounting rack 4. For example, the structure for supporting the photovoltaic mounting rack 4 is the roof 6 of a house. The lower end of the second connector 12 can be in contact with the roof 6 of the house. The lower end of the first connector 11 is movably connected to the upper end of the second connector 12 and can be locked by a locking structure. By the relative movement of the first connector 11 and the second connector 12, the relative position adjustment between the first end 1a and the second end 1b of the first connection structure 1 in at least one direction can be realized.

[0065] Optionally, the first connection structure 1 further includes a first locking structure 13. The first connector 11 and the second connector 12 are slidably connected and the relative position is locked by the first locking structure 13.

[0066] Specifically, when the first connector 11 and the second connector 12 slide relative to each other, the position adjustment of the first end 1a and the second end 1b of the first connection structure 1 in the relative sliding direction of the two can be realized. The relative position of the first connector 11 and the second connector 12 can be locked by the first locking structure 13. Thus, after the relative position adjustment of the first end 1a and the second end 1b of the first connection structure 1, the relative position of the two can be kept fixed. Since the position of the second end 1b of the first connection structure 1 is fixed, the position of the first end 1a is also fixed, and thus the position of the heat dissipation fin 31 can be kept fixed.

[0067] In this way, by setting the first connector 11 and the second connector 12 to be slidably connected, the relative position adjustment between the first end 1a and the second end 1b of the first connection structure 1 in at least one direction can be realized through their relative sliding, and the two are locked by the first locking structure 13. The structure is simple and has strong practicability.

[0068] As Figure 6As shown, optionally, one of the first connecting member 11 and the second connecting member 12 is provided with a slot 111, and the other of the first connecting member 11 and the second connecting member 12 is provided with a plug post 123. The plug post 123 is slidably inserted into the slot 111. A first connection hole 112 is provided on the wall of the slot 111. The first locking structure 13 passes through the first connection hole 112 and is connected to the second connecting member 12.

[0069] Exemplarily, the first connecting member 11 is generally in a long strip shape, such as a rod member. Its upper end is used to connect with the heat dissipation fin 31, and a structure for connecting with the heat dissipation fin 31 can be provided thereon, which will be exemplarily described later. At least a part of the second connecting member 12, such as the member body 121 described later, is in a long strip shape, such as a rod shape. The upper end of the member body 121 is connected to the first connecting member 11.

[0070] As Figure 2 、 3 As shown in FIGS. 5 and 6, it shows a case where the first connecting member 11 is provided with a slot 111, the opening of the slot 111 faces downward, and the slot 111 makes the first connecting member 11 in a hollow structure. It also shows a case where the upper end of the member body 121 of the second connecting member 12 forms a plug post 123, and the plug post 123 is inserted into the slot 111. The following description in this specification will be based on this example.

[0071] It should be understood that in another embodiment, it can also be that the first connecting member 11 is provided with a plug post 123, and the upper end of the member body 121 of the second connecting member 12 is provided with a slot 111, which will not be described in detail here.

[0072] It should be understood that the specific structure of the first locking structure 13 can be set as needed.

[0073] As Figure 2 、 Figure 5 And Figure 6 As shown, exemplarily, the first connection hole 112 is an elongated hole, and the elongated hole extends along the extending direction of the slot 111. The first locking structure 13 includes a first screw. The first screw passes through the first connection hole 112 and is threadedly connected to a second connection hole on the plug post 123, that is, the second connection hole is a threaded hole. Thus, by tightening the first screw, the first connecting member 11 and the second connecting member 12 can be pressed together to fix their relative positions, and by loosening the first screw, the fixing of their relative positions can be released.

[0074] Exemplarily, the first connection hole 112 is a threaded hole, and the first locking structure 13 includes a first screw. The first screw is threadedly connected to the first connection hole 112 and abuts against the plug post 123.

[0075] In this way, the arrangements of the slot 111 and the stud 123 can achieve reliable movement guidance for the first connecting member 11 and the second connecting member 12, and facilitate the structural arrangement of the first locking structure 13. The structure is simple and highly practical.

[0076] As Figures 5 - 8 shown, optionally, a receiving cavity 113 is provided at the first end 1a of the first connecting structure 1. The receiving cavity 113 has an opening 1131, and a set fin 311 in the heat dissipation fins 31 is inserted into the receiving cavity 113 through the opening 1131.

[0077] The set fin 311 is the part of the heat dissipation fins 31 of the power unit 3 that is connected to the receiving cavity 113. The structural form of the receiving cavity 113 is not limited. Its cross-sectional shape can be U-shaped, V-shaped, etc., as long as it can accommodate the set fin 311. This cross-section can be approximately understood as the plane determined by the width direction and the depth direction of the receiving cavity 113. Here, the width direction is the same as the opening width direction of the opening 1131.

[0078] In this way, the set fin 311 can be accommodated by the receiving cavity 113 to realize the positioning of the set fin 311 by the first end 1a of the first connecting structure 1, which is beneficial to ensuring the stability of the relative positions of the two, and preventing them from separating easily. For example, it can prevent them from separating easily when subjected to external forces such as wind force, and can enhance the position stability of the power unit 3.

[0079] Optionally, the first end 1a of the first connecting structure 1 is detachably connected or integrally connected to the heat dissipation fins 31. The specific manner of their detachable connection is not limited.

[0080] As Figure 2 and Figure 5 shown, optionally, a second locking structure 14 is provided at the first end 1a of the first connecting structure 1. The second locking structure 14 presses the set fin 311 against the first connecting structure 1, for example, against the first connecting member 11 of the first connecting structure 1.

[0081] Exemplarily, the second locking structure 14 includes a first threaded connector. The first threaded connector passes through the first connecting member 11 and the set fin 311. By tightening the first threaded connector, the connection between the two can be achieved, and by loosening the first threaded connector, the disassembly between the two can be achieved.

[0082] It should be understood that when the first end 1a of the first connecting structure 1 is detachably connected to the heat dissipation fins 31, the above-mentioned receiving cavity 113 can also be provided at the first end 1a of the first connecting structure 1. In this case, the second locking structure 14 presses the set fin 311 against the side wall of the receiving cavity 113.

[0083] As Figure 5 andFigure 6 As shown, optionally, a third connection hole 114 is provided on one side wall of the accommodation cavity 113, and the second locking structure 14 includes a first threaded connector that passes through the third connection hole 114 and is threadedly connected to the set fin 311.

[0084] The number of the set fins 311 can be one or more. Exemplarily, the heat dissipation fins 31 are sequentially spaced along the U-axis direction, and each heat dissipation fin 31 extends along the V-axis direction. The fins located at one or both ends of the heat dissipation fins 31 in the U-axis direction are defined as the set fins 311, and a first connection structure 1 is correspondingly provided for each set fin 311.

[0085] As Figure 5 shown, taking the heat dissipation fin 31 at one end in the opposite direction of the U-axis as the set fin 311 as an example, the side wall of the accommodation cavity 113 at one end in the opposite direction of the U-axis is the first side wall, and the side wall opposite to the first side wall is the second side wall. A third connection hole 114 is provided on the first side wall, and the first threaded connector passes through the third connection hole 114 and is threadedly connected to the set fin 311, thereby pressing the set fin 311 against the first side wall.

[0086] Optionally, a fourth connection hole is provided on one side wall of the accommodation cavity 113, and the second locking structure 14 includes a second threaded connector that is threadedly connected to the fourth connection hole and abuts against the set fin 311. Exemplarily, a fourth connection hole is provided on the first side wall, and the first threaded connector is threadedly connected to the fourth connection hole and abuts against the set fin 311, thereby pressing the set fin 311 against the second side wall. This solution is not shown in the figure.

[0087] As Figure 7 and 8 shown, optionally, the second locking structure 14 includes an elastic structure 115 that abuts against the set fin 311.

[0088] The composition form of the elastic structure 115 is not limited. When the set fin 311 is inserted into the accommodation cavity 113, the elastic structure 115 makes the set fin 311 contact at least one of the first side wall and the second side wall through elastic force, thereby increasing the friction between the set fin 311 and, for example, the second side wall, and increasing the stability of the relative position between the set fin 311 and the accommodation cavity 113.

[0089] Exemplarily, the elastic structure 115 can be integrally connected to the first side wall of the accommodation cavity 113. For example, the elastic structure 115 is an elastic bulge formed on the first side wall.

[0090] As Figure 7 and 8As shown, optionally, when the second locking structure 14 includes an elastic structure 115, the accommodation cavity 113 is formed by a bent plate member, and the elastic structure 115 is formed on the bent plate member.

[0091] For example, by bending the bent plate member, the first side wall forms a first inner convex portion 1151. The distance between the first side wall and the second side wall at the first inner convex portion 1151 reaches the minimum value, and this minimum value is less than the thickness of the set fin 311. By using the elastic force of the bent plate member, a relatively large frictional force can be obtained between the first inner convex portion 1151 and the set fin 311, ensuring the stability of their relative positions. In this case, the elastic structure 115 includes this first inner convex portion 1151.

[0092] As Figure 7 、 8 As shown, optionally, the elastic structure 115 includes a first elastic piece 1152, and the end of the first elastic piece 1152 is used to abut against the set fin 311.

[0093] In this case, the structure of the first elastic piece 1152 is relatively simple and easy to form. For example, the first elastic piece 1152 can be formed by a part of the first side wall. For example, the first elastic piece 1152 is formed by cutting a part of the first side wall to form the end.

[0094] Optionally, in the extending direction of the first elastic piece 1152 and gradually away from its end, the distance from the points on the first elastic piece 1152 to the inner bottom surface of the accommodation cavity 113 gradually increases.

[0095] Specifically, the upper end of the first elastic piece 1152 is connected to the main body of the first side wall, and the lower end of the first elastic piece 1152 forms the end. Under the elastic force of the first elastic piece 1152, the end abuts against the set fin 311, thereby pressing the set side wall against the second side wall. In some cases, for example, when the elastic force of the first elastic piece 1152 is large enough, the end of the first elastic piece 1152 can partially embed into the set fin 311, and the first elastic piece 1152 constitutes a structure similar to a barbed structure to prevent the set fin 311 from disengaging from the accommodation cavity 113. Or rather, the first elastic piece 1152 is clamped with the set fin 311 to prevent the set fin 311 from disengaging from the accommodation cavity 113.

[0096] Of course, it should be understood that the detachable connection manner between the first end 1a of the first connection structure 1 and the heat dissipation fin 31 is not limited to this. The two can also adopt detachable connection manners such as snap connection or magnetic connection, which will not be elaborated here.

[0097] Optionally, the first end 1a of the first connection structure 1 is integrally connected to the heat dissipation fin 31.

[0098] As Figures 10 - 11As shown, exemplarily, the first end 1a of the first connection structure 1 has a first plate-like structure, and the first connection structure 1 is detachably or integrally connected to the heat dissipation fin 31 through the first plate-like structure.

[0099] Specifically, to a certain extent, the heat dissipation performance of the heat dissipation fin 31 can be enhanced by using the first plate-like structure.

[0100] As Figure 10 and Figure 11 shown, it shows a solution where the first connecting member 11 includes a first plate-like structure and the first plate-like structure is integrally connected to the set fin 311. At the same time, the heat dissipation fins 31 on both sides of the set fin 311 can also be designed to be higher. On the one hand, it can ensure the heat dissipation performance of the set fin 311 and the heat dissipation fins 31 in its vicinity. On the other hand, in some cases (such as when the wind force is large and the first locking structure 13 of the first connection structure 1 fails), the heightened heat dissipation fins 31 can form a certain degree of support for the entire power unit 3 to a certain extent. For example, contacting the roof 6 of the house can assist in supporting the power unit 3 and reduce the displacement of the power unit 3.

[0101] Optionally, the second end 1b of the first connection structure 1 has a connection seat 122 fixedly or hingedly arranged, and the cross-sectional area of the part of the first connection structure 1 connected to the connection seat 122 is smaller than the end face area of the end of the connection seat 122, and the end of the connection seat 122 is the end far from the first end 1a of the first connection structure 1.

[0102] As Figure 5 、 6 shown, it shows the case where the second end 1b of the first connection structure 1 has a fixedly arranged connection seat 122.

[0103] Exemplarily, the second connecting member 12 includes a member body 121 and a connection seat 122. The connection seat 122 includes a second plate-like structure, and the second plate-like structure is fixedly connected to the lower end of the member body 121, and the end face area of the lower end of the second plate-like structure is larger than the end face area of the lower end of the member body 121.

[0104] In this case, the second end 1b of the first connection structure 1 can obtain a larger support surface with the structure (such as the roof 6 of the house) for supporting the photovoltaic mounting frame 4 through the connection seat 122, ensuring the support reliability of the first connection structure 1 at the second end 1b.

[0105] As Figure 9 shown, it shows the case where the second end 1b of the first connection structure 1 has a hingedly arranged connection seat 122.

[0106] At this time, the connecting seat 122 includes a second plate-like structure and an ear seat. The upper end of the second plate-like structure is fixedly connected to the ear seat, for example, integrally connected. The ear seat is rotatably connected to the lower end of the component body 121, for example, connected by a damping rotating shaft.

[0107] In this way, it can not only ensure that a large supporting surface can be obtained between the second end 1b of the first connecting structure 1 and the structure (such as the house roof 6) for supporting the photovoltaic mounting frame 4 through the connecting seat 122, but also adapt to the fitting pose requirements of the corresponding fitting surface by the rotation of the connecting seat 122 relative to the first end 1a of the first connecting structure 1. It should be understood that the fitting surface is formed on the surface of the structure (such as the house roof 6) for supporting the photovoltaic mounting frame 4.

[0108] In a second aspect, the photovoltaic system provided by the present disclosure includes the mounting assembly and the power unit 3 of the above embodiments. The second connecting structure 2 of the mounting assembly is connected to the set end of the power unit 3, and the first end 1a of the first connecting structure 1 of the mounting assembly is connected to the heat dissipation fins 31 of the power unit 3. This photovoltaic system has the beneficial effects of the mounting assembly, which will not be elaborated here one by one.

[0109] Optionally, the photovoltaic system further includes a photovoltaic mounting frame 4 and a photovoltaic panel 5; the photovoltaic panel 5 is mounted on the photovoltaic mounting frame 4, the set end of the power unit 3 is connected to the photovoltaic mounting frame 4 through the second connecting structure 2, and the second end 1b of the first connecting structure 1 is connected to at least one of the photovoltaic mounting frame 4 and the supporting structure of the photovoltaic mounting frame 4.

[0110] As Figure 1 shown, it shows the situation where the photovoltaic mounting frame 4 is supported on the house roof 6, and the house roof 6 is a pitched roof. However, obviously, it is not limited thereto. The house roof 6 can be a flat roof or the like.

[0111] In this way, with the help of the photovoltaic mounting frame 4 and the house roof 6, etc., the mounting assembly can realize the reliable installation of the power unit 3, with a simple structure and strong practicability.

[0112] Optionally, when the power unit 3 is installed (or fixed) through the mounting assembly, the large surface of the power unit 3 is arranged opposite to the large surface of the photovoltaic panel 5; the heat dissipation fins 31 are arranged on the side of the power unit 3 facing away from the photovoltaic panel 5.

[0113] For example, the large surface of the power unit 3 is parallel to the large surface of the photovoltaic panel 5, or there is an included angle between the two, and the included angle is less than, for example, 25°, for example, less than 15°. Those skilled in the art should understand the specific meaning of the large surfaces of the power unit 3 and the photovoltaic panel 5. It does not mean that the surface of the power unit 3 must be a plane. The large surface can be a virtual plane, and this large surface is parallel to the plane determined by the V axis and the U axis.

[0114] Thus, it is beneficial to reduce the requirement of the power unit 3 for the layout space in the W-axis direction, which is beneficial to reducing the overall installation height of the photovoltaic panel 5 and improving the wind resistance performance and structural stability of the entire photovoltaic system.

[0115] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will all fall within the protection scope of the present disclosure.
