Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of components of photovoltaic modules, and in particular to a photovoltaic frame and a photovoltaic module. BACKGROUND

[0002] Solar photovoltaic technology is a clean energy technology that converts solar energy into electrical energy. A photovoltaic module is a core component of a solar photovoltaic system.

[0003] In related technologies, a photovoltaic module mainly includes glass, adhesive film, cell pieces, solder strips, and structural layers such as a frame. The glass, adhesive film, cell pieces, and solder strips are formed into a laminated piece through a laminating process, and the edges of the laminated piece are embedded in a clamping groove of the frame. The four corners of the frame adopt a splicing structure, so that there are gaps at the four corners of the assembled frame, which become a "hot spot" for water vapor intrusion.

[0004] However, the inventors have realized that, in the preparation process of the photovoltaic module, due to the complex preparation process of the photovoltaic module, it is difficult to completely uniformly control the thickness of the laminated piece. After the laminated piece is installed in the clamping groove of the frame, the laminated piece may cause a gap between the glass and the adhesive film due to improper stress release, so that water vapor from the outside intrudes into the inside of the frame from the above-mentioned gap of the frame, thereby corroding the cell pieces and the solder strips and affecting the power generation performance of the photovoltaic module. CONTENT OF THE INVENTION

[0005] One or more embodiments of the present application provide a photovoltaic frame and a photovoltaic module to solve or at least partially alleviate the problem of water vapor intrusion at the gaps of the four corners of the frame in related technologies affecting the power generation performance of the photovoltaic module.

[0007] A photovoltaic frame includes a frame body and a stop piece. An inner side of the frame body is provided with a clamping groove for installing a laminated piece. A side wall of the frame body is provided with an injection hole that penetrates through the side wall and is in communication with the clamping groove. A resettable stop piece is arranged at an edge of the injection hole. The stop piece is adapted to the shape of the injection hole.

[0008] By adopting the technical scheme, specifically, the glue injection hole is arranged on the frame body, the resettable baffle is arranged at the edge of the glue injection hole, after the lamination of the photovoltaic module is formed, the edge of the lamination is arranged in the clamping groove of the frame body, then the sealant is injected into the clamping groove of the frame body from the glue injection hole, so that the sealant flows to the gap between the frame body and the lamination and the four corners of the frame body, thereby sealing the gap between the frame and the lamination and the gap at the four corners of the frame during assembly, improving the sealing effect between the frame and the lamination, reducing the risk of external water vapor and moisture invading the inside of the lamination of the photovoltaic module, and ensuring the power generation performance of the photovoltaic module including the frame.

[0009] Furthermore, after the sealant is injected into the clamping groove on the inside of the frame body, the baffle can be reset to block, for example, be embedded back into the glue injection hole, so that the baffle not only extrudes the sealant in the frame body, but also makes the sealant on the inside of the frame body more fully filled, and the baffle embedded back into the glue injection hole can also improve the strength of the frame body at the glue injection hole.

[0010] In some embodiments, the clamping groove is used for clamping the edge of the lamination, and at least part of the glue injection hole is located in the upper half of the clamping groove.

[0011] In some embodiments, the glue injection hole is used for injecting the sealant into the inside of the frame body, the inner wall of the clamping groove is provided with a flow guide channel for guiding the sealant, and the flow guide channel is aligned with the glue injection hole.

[0012] In some embodiments, the flow guide channel includes a plurality of protruding structures arranged vertically and spaced apart, and a first groove formed between adjacent two protruding structures is used for flowing the sealant.

[0013] Alternatively, the flow guide channel includes a plurality of second grooves arranged vertically and spaced apart, and the second grooves are recessed in the groove bottom of the clamping groove.

[0014] In some embodiments, the extension direction of the flow guide channel is parallel to the extension direction of the clamping groove.

[0015] In some embodiments, the baffle is integrally formed with the frame body.

[0016] In some embodiments, the baffle is formed by punching and bending a local part of the photovoltaic frame, and the bending angle of the baffle relative to the frame body ranges from 30 degrees to 60 degrees.

[0017] In some embodiments, a plurality of glue injection holes are arranged, and the plurality of glue injection holes are sequentially arranged along the length direction of the frame body.

[0018] Compared with the related art, one or more embodiments of the present application include at least one of the following beneficial technical effects:

[0019] In a second aspect of the present application, a photovoltaic module is provided by using the following technical solution:

[0020] A photovoltaic module includes the photovoltaic frame as described above, and further includes a laminated piece connected with the frame body of the photovoltaic frame, and a sealant is filled between the laminated piece and the frame body.

[0021] Since the photovoltaic module includes the photovoltaic frame, the photovoltaic module has all the technical effects of the photovoltaic frame, which are not described herein again.

[0045] Figure 1 One of the partial structural schematic diagrams of a photovoltaic module according to some embodiments of the present application.

[0046] One or more embodiments of the present application disclose a photovoltaic frame. Referring to Figure 1 , the photovoltaic frame comprises a frame body 1 and a stop sheet 2, the inner side of the frame body 1 is provided with a clamping groove 111 for mounting a laminated piece 3, the side wall of the frame body 1 is provided with a glue injection hole 110 penetrating through the side wall and communicating with the clamping groove 111, the edge of the glue injection hole 110 is provided with a resettable stop sheet 2, and the stop sheet 2 is matched with the shape of the glue injection hole 110.

[0047] In at least one embodiment, the frame body 1 can be a plate structure with a folded edge, or a rectangular frame structure. The inner side of the frame body 1 refers to the side of the frame body 1 facing the laminated piece, and the clamping groove 111 can be formed on the side of the frame body 1 facing the laminated piece, which is along Figure 2 The size of the Z-axis direction in the coordinate system is the width of the clamping groove 111, and the width of the clamping groove 111 can be greater than the thickness of the laminated piece 3, so as to facilitate the smooth embedding (or insertion) of the edge of the laminated piece 3 in the clamping groove 111.

[0048] At least one glue injection hole 110 can be provided on the side wall of the frame body 1, and the laminated piece 3 can be arranged on the inner side of the frame body 1 which is in the rectangular frame structure.

[0049] The stop sheet 2 matched with the shape of the glue injection hole 110 means that after injecting glue into the inner side of the frame body 1 through the glue injection hole 110, an acting force can be applied to the stop sheet 2 to shield the entire glue injection hole 110 and the edge of the glue injection hole 110, or the stop sheet 2 is inserted into the glue injection hole 110.

[0050] The resettable stop sheet 2 arranged at the edge of the glue injection hole 110 means that after injecting the sealant 4 into the inner side of the frame body 1 from the glue injection hole 110, the stop sheet 2 can rotate relative to the frame body 1 under the action of an external force to shield or embed back into the glue injection hole 110, so as to not only prevent the injected sealant 4 between the frame body 1 and the laminated piece 3 from flowing out from the glue injection hole 110, but also prevent foreign matters such as dust from the outside from invading into the inner side of the frame body 1 through the glue injection hole 110.

[0051] The sealant 4 can be butyl rubber, which is a type of synthetic rubber synthesized from isobutylene and a small amount of isoprene. It can effectively ensure the prevention of water vapor and moisture intrusion at the four corners of the frame body 1 in the photovoltaic module and between the frame body 1 and the laminate 2.

[0052] The slot 111 is used for the edge of the laminate 3 to be engaged or inserted, so as to support and position the laminate 3 through the slot 111, preventing the edge of the laminate 3 from tilting downward and detaching from the frame body 1, thereby improving the installation stability of the laminate 3. An injection hole 110 can be opened on the frame body 1, and a resettable baffle 2 is provided at the edge of the injection hole 110. After the laminate 3 of the photovoltaic module is formed, the edge of the laminate 3 can be placed in the slot of the frame body 1. Then, sealant 4 can be injected into the slot of the frame body 1 through the injection hole 110, allowing the sealant 4 to flow between the frame body 1 and the laminate 3, as well as at the four corners of the frame body 1. This sealant 4 seals the gap between the frame and the laminate 3, as well as the gaps generated at the four corners during frame assembly, improving the sealing effect between the frame and the laminate 3, reducing the risk of external moisture and humidity intruding into the interior of the laminate 3 of the photovoltaic module, and ensuring the power generation performance of the photovoltaic module, including the frame.

[0053] Furthermore, after the sealant 4 is injected into the groove on the inner side of the frame body 1, the baffle 2 can be operated to reset and cover, for example, by being inserted back into the injection hole 110. Thus, the baffle 2 not only squeezes the sealant 4 inside the frame body 1, making the sealant 4 inside the frame body 1 more fully filled, but also the baffle 2 inserted back into the injection hole 110 can improve the strength of the frame body 1 at the injection hole 110.

[0054] Figure 2 This is a schematic diagram of the structure in which the sealant 4 is located in the slot 111 of the frame body 1 according to some embodiments of this application; Figure 3 This is one of the structural schematic diagrams of a photovoltaic frame according to some embodiments of this application.

[0055] In some embodiments, combined with Figure 2 and Figure 3 As shown, at least a portion of the glue injection hole 110 is located in the upper half of the slot 111.

[0056] In at least one embodiment, the upper half of the card slot 111 refers to the portion of the card slot 111 in... Figure 2 The portion above the horizontal line E. "At least a portion of the injection hole 110 is located in the upper half of the slot 111" means that the entire injection hole 110 is located in the upper half of the slot 111;

[0057] Or see Figure 2As shown, a portion of the glue injection hole 110 is located in the upper half of the clamping groove 111, and another portion of the glue injection hole 110 is located in the lower half of the clamping groove 111. For example, the center line of the clamping groove 111 in the horizontal direction can be represented by the letter E, and the central part of the glue injection hole 110 can be represented by the letter D. The central part of the glue injection hole 110 above the center line of the clamping groove 111 means that the position of the central part of the glue injection hole 110 (letter D) is higher than the center line of the clamping groove 111 (letter E). Figure 3 Figure 3 The central part of the glue injection hole 110 above the center line of the clamping groove 111 means that the position of the central part of the glue injection hole 110 (letter D) is higher than the center line of the clamping groove 111 (letter E).

[0058] The central part of the glue injection hole 110 above the center line of the clamping groove 111 means that the position of the central part of the glue injection hole 110 (letter D) is higher than the center line of the clamping groove 111 (letter E). Figure 2 When the sealant 4 completely fills the inner wall of the clamping groove 111 and the laminated piece 3, the position of the sealant 4 in the clamping groove 111 is shown in

[0059] Figure 4 The second schematic view of the photovoltaic frame according to some embodiments of the present application mainly embodies the structure of the first flow guide channel.

[0060] In some embodiments, in combination with Figure 4 As shown, the inner side wall of the clamping groove 111 is provided with a flow guide channel 112 for guiding the sealant 4, and the flow guide channel 112 is aligned with the glue injection hole 110.

[0061] In at least one embodiment, the alignment of the flow guide channel 112 with the glue injection hole 110 means that the end of the flow guide channel 112 communicates with the glue injection hole 110, so that the glue injected from the glue injection hole 110 into the frame body 1 can smoothly enter the flow guide channel 112 and extend along the extension direction of the flow guide channel 112.

[0062] Since the glue injection hole 110 penetrates the side wall of the frame body 1, the flow guide channel 112 is arranged at the position adjacent to the glue injection hole 110 on the side wall of the frame body 1 or the side wall of the clamping groove 111, so that the end of the flow guide channel 112 can be received by the glue injection hole 110.

[0063] ​A flow guide channel 112 can be arranged on the inner side wall of the card slot 111 corresponding to the laminated piece 3. The flow guide channel 112 is used to guide the sealant 4 injected from the glue injection hole 110, so that the sealant 4 can quickly flow to fill the gap between the frame body 1 and the laminated piece 3 and the gap at the corner of the photovoltaic frame. Not only can the sealing efficiency between the frame body 1 and the laminated piece 3 be improved, but also the sealant 4 can be prevented from accumulating and solidifying near the glue injection hole 110, and the problem of uneven distribution of the sealant 4 on the inner side of the frame body 1 can be avoided, so as to improve the sealing effect of the sealant 4 between the frame body 1 and the laminated piece 3. In addition, the sealant 4 in the flow guide channel 112 can also increase the contact area with the frame body 1, and accordingly increase the bonding effect of the frame body 1 and the laminated piece 3.

[0064] Figure 5 For the third schematic view of the structure of the photovoltaic frame according to some embodiments of the present application, the structure of the second flow guide channel is mainly embodied.

[0065] In some embodiments, the flow guide channel 112 can adopt the following two structural modes. First, as shown in Figure 4 , the flow guide channel 112 includes a plurality of protruding structures 1121 arranged vertically and spaced apart, and a first groove 1122 is formed between adjacent two protruding structures 1121 as the flow channel of the sealant 4.

[0066] Alternatively, second, as shown in Figure 5 , the flow guide channel 112 includes a plurality of second grooves 1123 arranged vertically and spaced apart, and the second grooves 1123 are arranged in the inner wall of the card slot 111.

[0067] In at least one embodiment, in the first flow guide channel 112 structure scheme described above, as shown in Figure 4 , a plurality of protruding structures 1121 are arranged vertically and spaced apart along Figure 4 the Z-axis direction of the coordinate system, and the protruding structures 1121 protrude from the inner side wall of the card slot 111. At this time, a first groove 1122 is formed between adjacent two protruding structures 1121, and the first groove 1122 can be flush with the inner side wall of the card slot 111, and the sealant 4 can flow in the first groove 1122. The protruding structures 1121 can be formed on the inner side wall of the card slot 111 by welding or die casting.

[0068] When the edge of the laminated piece 3 is clamped in the clamping groove 111 of the frame body 1, a small gap can exist between the edge side wall of the laminated piece 3 and the convex structure 1121. When the sealant 4 is injected into the clamping groove 111 of the frame body 1 from the injection hole 110, the sealant 4 flows from the top to the bottom in the small gap between the edge of the laminated piece 3 and the inner wall of the clamping groove 111, and flows along the extension direction of the first groove 1122 of the flow guide channel 112 to other parts of the clamping groove 111 without the injection hole 110, so that the sealant 4 can quickly fill all positions between the frame body 1 and the laminated piece 3 and the corners in the photovoltaic frame, effectively improving the sealing effect of the photovoltaic module.

[0069] In the above-mentioned second structure of the flow guide channel 112, in combination with Figure 5 as shown in the drawings, the flow guide channel 112 includes a plurality of second grooves 1123 arranged vertically and spaced apart, and the plurality of second grooves 1123 are arranged along Figure 5 the Z-axis direction of the coordinate system, and each second groove 1123 is recessed in the groove bottom of the clamping groove 111, in other words, each second groove 1123 is not protruded from the groove bottom of the clamping groove 111, and the sealant 4 can flow in the second groove 1123. The second groove 1123 can be formed by cutting process or milling process such as groove milling process on the inner side wall of the clamping groove 111.

[0070] The clamping groove 111 has Figure 5 the side wall of the X-axis direction of the coordinate system as the groove bottom of the clamping groove 111.

[0071] When the edge of the laminated piece 3 is clamped in the clamping groove 111 of the frame body 1, a small gap can exist between the edge side wall of the laminated piece 3 and the inner side wall of the clamping groove 111. When the sealant 4 is injected into the clamping groove 111 of the frame body 1 from the injection hole 110, the sealant 4 flows from the top to the bottom in the small gap between the edge of the laminated piece 3 and the inner wall of the clamping groove 111, and flows along the extension direction of the second groove 1123 of the flow guide channel 112 to other parts of the clamping groove 111 without the injection hole 110, so that the sealant 4 can quickly fill all positions between the frame body 1 and the laminated piece 3 and the corners in the photovoltaic frame, effectively improving the sealing effect of the photovoltaic module.

[0072] In some embodiments, in combination with Figure 4 as shown in the drawings, the extension direction of the flow guide channel 112 is parallel to the extension direction of the clamping groove 111.

[0073] In at least one embodiment, as mentioned above, since the frame of the photovoltaic module can be a rectangular frame structure, the frame of the rectangular frame structure can have four frame bodies 1, and the four frame bodies 1 can surround the rectangular frame structure, Figure 4 one of the frame bodies 1 is embodied, Figures 8 to 11The two frame bodies 1 are shown in the figure.

[0074] Each frame body 1 can be substantially in a straight plate structure, and a clamping groove 111 is formed on each frame body 1. The extending direction of each clamping groove 111 can be parallel to the extending direction of the frame body 1.

[0075] Since the extending direction of the flow guide channel 112 is parallel to the extending direction of the clamping groove 111, the sealant 4 entering from the glue injection hole 110 can quickly flow along the flow guide channel 112 to uniformly fill the gap between the inner side wall of the clamping groove 111 and the laminated piece 3 and the gap at the corner of the photovoltaic frame, further improving the sealing effect on the photovoltaic module.

[0076] In some embodiments, the baffle 2 and the frame body 1 are integrally formed.

[0077] In at least one embodiment, the baffle 2 and the frame body 1 can be configured as an integral structure, which can improve the connection stability of the baffle 2 and the frame body 1.

[0078] Figure 6 The figure shows the state of the baffle on the frame body according to some embodiments of the present application before punching and bending, Figure 7 The figure shows the state of the baffle on the frame body according to some embodiments of the present application during punching and bending.

[0079] In some embodiments, in combination with Figure 6 and Figure 7 It is shown that the baffle 2 and the frame body 1 can be configured as an integral structure in the following manner, for example, the baffle 2 is formed by punching and bending the local part of the photovoltaic frame, and the bending angle of the baffle 2 relative to the frame body 1 ranges from 30 degrees to 60 degrees.

[0080] In at least one embodiment, taking the plate structure of the frame body 1 as an example, the baffle 2 on the frame body 1 can be formed in the following manner, for example, the punching and bending action of the frame body 1 can be performed by the punching head 5 of the stamping equipment. The bottom of the punching head 5 can be a wedge-shaped structure. Before the stamping action, the punching head 5 can be placed on the frame body 1 with a certain interval therebetween. The position of the frame body 1 is adjusted so that the position of the local part to be punched on the frame body 1 corresponds to the position of the punching head 5, as shown in Figure 6 Then the downward movement of the punching head 5 can be controlled to apply a downward stamping force to the frame body 1 to bend the local part downward on the frame body 1. At this time, the bent part on the frame body 1 can be the baffle 2 (see Figure 7 The hole formed at the corresponding position of the baffle 2 on the frame body 1 is the glue injection hole 110.

[0081] wherein, Figure 6 the value of the bottom slope of the stamping tool head can be represented by the letter b, then Figure 7 the value of the bending angle of the blocking piece 2 relative to the frame body 1 can be represented by c, c = 90-b, the bending angle c of the blocking piece 2 can range from 30 degrees to 60 degrees, preferably 45 degrees. The bending angle of the blocking piece 2 is directly related to the bottom slope of the punching tool head 5 and the depth of the punching.

[0082] Since the blocking piece 2 is formed by punching and bending the local part of the photovoltaic frame, in other words, the blocking piece 2 and each frame body 1 of the photovoltaic frame can be an integral structure, thereby ensuring the connection stability of the blocking piece 2 relative to the frame body 1 and reducing the risk of the blocking piece 2 separating from the frame body 1. Furthermore, since the bending angle of the blocking piece 2 relative to the frame body 1 ranges from 30 degrees to 60 degrees, in other words, the bending angle of the blocking piece 2 can meet the operation of smoothly injecting the sealant 4 from the glue injection hole 110 to the inside of the frame body 1, thereby improving the convenience of filling the sealant 4 inside the frame body 1.

[0083] In some embodiments, in combination with Figure 1 As shown, the shape of the glue injection hole 110 is a rectangular hole, and the shape of the blocking piece 2 matches the shape of the glue injection hole 110.

[0084] In at least one embodiment, the rectangular hole can be a rectangular hole or a square hole, and the shape of the blocking piece 2 matches the shape and size of the glue injection hole 110.

[0085] Since the shape of the glue injection hole 110 is a rectangular hole, and the shape of the blocking piece 2 matches the shape of the glue injection hole 110, the blocking piece 2 can be smoothly embedded in the rectangular hole, avoiding the problem that only part of the blocking piece 2 is embedded in the rectangular hole during the resetting process, and accordingly ensuring the blocking effect of the blocking piece 2 on the glue injection hole 110.

[0086] In some embodiments, a plurality of glue injection holes 110 are provided, and the plurality of glue injection holes 110 are sequentially arranged along the length direction of the frame body 1.

[0087] In at least one embodiment, a plurality of glue injection holes 110 can be provided on each frame body 1, and the heights of the plurality of glue injection holes 110 are the same. Preferably, since the frame body 1 can be a plate structure, for example, a rectangular plate, the glue injection holes 110 can be provided at both ends of the length direction of each frame body 1.

[0088] Due to the plurality of glue injection holes 110 arranged on each frame body 1 and the plurality of glue injection holes 110 distributed along the extension direction of the frame body 1, the operator can simultaneously inject the sealant 4 from the plurality of glue injection holes 110 of each frame body 1 by means of the glue injection equipment, thereby further improving the sealing efficiency of the photovoltaic module.

[0090] The present application one or more embodiments also disclose a photovoltaic module. Referring to Figures 8 to 11 , the photovoltaic module comprises the photovoltaic frame as described in the above embodiments, and further comprises a laminated member 3 connected with the frame body 1 of the photovoltaic frame, and a sealant 4 filled between the laminated member 3 and the frame body 1.

[0091] In at least one embodiment, each edge of the laminated member 3 can correspond to the clamping groove 111 of the frame body 1 respectively.

[0092] In at least one embodiment, Figure 8 Fig. 2 is a partial structural schematic view of a photovoltaic module according to some embodiments of the present application, mainly showing the relative position relationship between two of the four photovoltaic frames and the laminated member, and the other two photovoltaic frames are not shown.

[0093] In some embodiments, in combination with Figure 8 As shown in the figure, the frame body 1 is provided with four.

[0094] In at least one embodiment, the photovoltaic module can include four frame bodies 1 which are sequentially connected end to end to form a rectangular frame structure. If the four frame bodies 1 have the same length, the four frame bodies 1 can form a square frame structure. If the four frame bodies 1 have different lengths, for example, two longer frame bodies 1 are arranged in a horizontal direction and two shorter frame bodies 1 are arranged in a vertical direction, the four frame bodies 1 can form a rectangular frame structure. Adjacent two frame bodies 1 can be connected by a connecting member, such as a corner code, to improve the assembly convenience of the photovoltaic frame in the photovoltaic module.

[0095] Each frame body 1 is provided with a clamping groove 111 on the inner side wall. The laminated member 3 can be a rectangular plate structure, and thus the part of each side edge of the laminated member 3 can be inserted into the clamping groove 111 of each frame body 1.

[0096] Each frame body 1 can be provided with a glue injection hole 110, so that the operator can inject sealant 4 into the clamping groove 111 of the frame body 1 from the glue injection hole 110 of each frame body 1. The sealant 4 can enter the gap between the laminated member 3 and the frame body 1 and the corner of the frame body 1 along the flow channel 112 of the inner side wall of the clamping groove 111. In other words, the gap between the inner side wall of each frame body 1 and the corresponding side edge of the laminated member 3 is filled with sealant 4, which improves the sealing efficiency between the frame body 1 and the laminated member 3 in the photovoltaic module.

[0097] The processing process of the photovoltaic frame and the assembly process with the laminated member 3 are as follows:

[0098] In the forming stage of the frame, the end part of each frame body 1 in the extension direction can be punched and bent outward by the punching tool head 5 of the punching equipment. The bent part of the frame body 1 can be a baffle 2. The through hole corresponding to the baffle 2 on the frame body 1 is a glue injection hole 110, which is mainly used for injecting sealant 4 between the frame body 1 and the laminated member 3 in the later stage, as shown in Figure 6 and Figure 7 .

[0099] In the frame assembly stage, two of the four frame bodies 1 of the frame are connected (for example, connected and fixed by a connecting member such as a corner code), and then the adjacent two side edges of the laminated member 3 are clamped into the clamping grooves 111 of the two frame bodies 1, as shown in Figure 8 and Figure 9 .

[0100] Then, by using a glue injection equipment with butyl glue, the glue injection nozzle is inserted into the glue injection hole 110 and the sealant 4 such as butyl glue is injected into the inner side of the frame body 1 until the butyl glue is fully filled and overflowed out of the outer side of the glue injection hole 110.

[0101] The secondary assembling is performed by the assembling device 6 to embed the bent position, i.e. the blocking piece 2, back into the glue injection hole 110 by extrusion force, as shown in Figure 10 and Figure 11 .

[0102] Therefore, the above-mentioned way of filling the sealant 4 into the inner side of the frame body 1 through the glue injection hole 110 can effectively solve the problem that the water vapor easily invades from the gaps at the four corners of the frame and the gap between the frame and the laminated piece 3, and affects the quality of the laminated piece, and the butyl glue with excellent water vapor resistance is used as the sealant 4 to better protect the four corners of the frame.

[0103] The beneficial effects of the photovoltaic module of the embodiment relative to the prior art are the same as the above-mentioned photovoltaic frame, which will not be described here.

Those skilled in the art should understand that the present application is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only the principles of the present application. Various changes and improvements can be made without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the claimed present application.
