[0040] Referring to FIGS. 1-4, the present application provides a photovoltaic module, which includes a laminate 100 and a frame surrounding the periphery of the laminate 100, for example, a first frame length is greater than a second frame, the first frame is a long frame, and the second frame is a short frame. The direction perpendicular to the first frame of the photovoltaic module is the first frame direction (or long frame direction, i.e., the left-right direction as shown in FIG. 1), and the direction perpendicular to the second frame of the photovoltaic module is the second frame direction (or short frame direction, i.e., the up-down direction as shown in FIG. 1). The photovoltaic module is provided with an overlap area in the second frame direction, which is configured to overlap with adjacent other photovoltaic modules, overlap with a cement tile 700, or overlap with both adjacent other photovoltaic modules and the cement tile 700. The second frame is provided with a connecting structure, which can be connected with adjacent other photovoltaic modules, connected with the cement tile 700, or connected with both adjacent other photovoltaic modules and the cement tile 700. In one embodiment, the connecting structure can be configured to mount a connecting member connected with adjacent other photovoltaic modules and the cement tile 700.

[0041] In the embodiment, the first frame includes a first frame member 1000 and a second frame member 2000 oppositely arranged along the second frame direction, and the overlap area is located on the side of the laminate 100 close to the second frame member 2000. The second frame includes a third frame member 3000 and a fourth frame member 4000 oppositely arranged along the first frame direction, and the connecting structure is arranged on the side of the third frame member 3000 and the fourth frame member 4000 away from the laminate 100. The connecting member includes a sealing male connector 3300 and a sealing female connector 4300 arranged on the third frame member 3000 and the fourth frame member 4000, respectively.

[0042] The laminate 100 has opposite first and second long side edges 100a and 100b and opposite first and second short side edges 100c and 100d. The photovoltaic module includes the first frame member 1000, the second frame member 2000, the third frame member 3000, and the fourth frame member 4000 as shown in FIGS. 4 and 5, so that the first frame member 1000 and the second frame member 2000 of the photovoltaic module can be arranged on the opposite first and second long side edges 100a and 100b of the laminate 100, respectively, and the third frame member 3000 and the fourth frame member 4000 of the photovoltaic module can be arranged on the opposite first and second short side edges 100c and 100d of the laminate 100, respectively, thereby constructing a brand-new photovoltaic module.

[0043] The laminated piece 100 can be used as a new photovoltaic module product after connecting the above-mentioned frame members, and can be directly used in a photovoltaic system as shown in FIG. 4. When assembling a tile roof, the new photovoltaic module can be directly used in a photovoltaic power generation system, or the arrangement structure of the photovoltaic module, and cooperates with the overlapping hanging piece 300, the overlapping support 400 and the locking member 500 to easily complete the assembly work. When a photovoltaic module needs to be maintained, the photovoltaic module with problems can be directly disassembled, and then the same new photovoltaic module is used as a replaceable unit product to cooperate with the overlapping hanging piece 300, the overlapping support 400 and the locking member 500 to be assembled at the original position. The entire assembly process and maintenance process are in a unit replacement mode, which is convenient and efficient to operate.

[0044] As shown in FIG. 4, the opposite first long side 100a and the second long side 100b of each laminated piece 100 are respectively provided with a first frame member 1000 and a second frame member 2000, and the overlapping hanging piece 300 can be detachably connected with the first frame member 1000 on the laminated piece 100, for example, inserted, threaded, or the like. The overlapping support 400 can form an accommodation chamber 600, and the second frame member 2000 on the laminated piece 100 is used to assemble in the accommodation chamber 600. As shown in FIG. 4, the photovoltaic module and the overlapping hanging piece 300 and the overlapping support 400 form an overlapping structure, which is suitable for continuous overlapping between a plurality of adjacent photovoltaic modules, and a large number of photovoltaic modules are assembled on the tile roof.

[0045] As shown in FIG. 4, when two adjacent photovoltaic modules are overlapped, the first frame member 1000 on one side of the photovoltaic module can be used to connect the overlapping hanging piece 300, and the second frame member 2000 on the other side of the photovoltaic module can be used to connect the overlapping support 400. Then the overlapping support 400 and the overlapping hanging piece 300 are hung and matched, and the locking member 500 is used to lock the overlapping support 400 and the overlapping hanging piece 300, so that the adjacent photovoltaic modules can be connected by the overlapping structure formed by the frame members, the overlapping hanging piece 300 and the overlapping support 400. The overlapping between the remaining photovoltaic modules can be repeated in the above-mentioned manner, which is not limited herein. When a large number of photovoltaic modules are overlapped, the overlapping support 400 can also be used to connect the batten 200 or the flat tile, so as to fix and install a large number of photovoltaic modules on a suitable tile roof, and realize the layout of the photovoltaic module.

[0046] Referring to FIG. 4, for example, a plurality of photovoltaic modules are arranged along the second frame direction. The first frame member of one photovoltaic module is detachably connected with the overlapping hanging piece 300 between two adjacent photovoltaic modules. The second frame member of the other adjacent photovoltaic module is connected with the overlapping support 400. The overlapping support 400 is provided with a receiving cavity for receiving the second frame member. The second frame member is arranged in the receiving cavity of the overlapping support 400. The overlapping hanging piece 300 is connected with the overlapping support 400. The first frame member of one photovoltaic module is overlapped on the overlapping area of the other adjacent photovoltaic module. At this time, the locking member 500 is connected with the overlapping hanging piece 300, and the first end of the locking member 500 abuts against the connection between the overlapping support 400 and the overlapping hanging piece 300, so as to lock the connection between the overlapping hanging piece 300 and the overlapping support 400.

[0047] In one embodiment, the overlapping hanging piece 300 can include a first assembly part 310 for connecting one of the two adjacent photovoltaic modules, and a first clamping part 320 connected with the first assembly part 310. The overlapping support 400 can include a second assembly part 410 for connecting the other of the two adjacent photovoltaic modules, and a second clamping part 420 connected with the second assembly part 410. The first clamping part 320 is clamped with the second clamping part 420. The second assembly part 410 is provided with a receiving cavity for receiving the end of the other of the two adjacent photovoltaic modules. The overlapping hanging piece 300 is arranged on one side of the overlapping support 400. For example, referring to FIG. 4, the two adjacent photovoltaic modules are overlapped. The first frame member 1000 of the upper photovoltaic module is overlapped on the upper part of the overlapping area of the lower photovoltaic module. The first assembly part 310 is connected with the first frame member 1000 of the upper photovoltaic module by clamping. The second frame member 2000 of the lower photovoltaic module is embedded in the second assembly part 410 of the overlapping support 400. The second clamping part 420 of the overlapping support 400 is clamped with the first assembly part 310 of the overlapping hanging piece 300. The overlapping support 400 is fixed on the batten of the roof, so as to overlap the two adjacent photovoltaic modules. The first frame member 1000 is provided with a connection groove structure matched with the structure of the first assembly part 310.

[0048] Therefore, by setting the overlapping hanging piece 300 and the overlapping support 400, the first assembly part 310 of the overlapping hanging piece 300 is connected with one of the two adjacent photovoltaic modules, the second assembly part 410 of the overlapping support 400 is connected with the other one of the two adjacent photovoltaic modules, and the second clamping part 420 of the overlapping support 400 is clamped with the first clamping part 320 of the overlapping hanging piece 300. During assembly, only the second clamping part 420 and the first clamping part 320 need to be clamped, so that the assembly of the two adjacent photovoltaic modules can be realized, which is beneficial to reduce the installation difficulty. When one of the two adjacent photovoltaic modules needs to be replaced, the second clamping part 420 and the first clamping part 320 can be opened, thereby facilitating independent disassembly and assembly.

[0049] In one embodiment, the locking member 500 is detachably arranged on one of the overlapping hanging piece 300 and the overlapping support 400, and the clamping part of the other one of the overlapping hanging piece 300 and the overlapping support 400 is limited, so that the first clamping part 320 and the second clamping part 420 are kept clamped. By arranging the locking member 500, the first clamping part 320 and the second clamping part 420 can be limited, so that the first clamping part 320 and the second clamping part 420 are stably kept in the clamped state, the clamping stability of the first clamping part 320 and the second clamping part 420 is improved, and the assembly stability of the two adjacent photovoltaic modules is improved, and the wind lifting resistance is improved. It should be noted that when the locking member 500 is limited, it can abut against the first clamping part 320 or the second clamping part 420 to be limited, or there can be a small gap between the locking member 500 and the first clamping part 320 or the second clamping part 420 to be limited, so as to avoid the clamping part to be limited from loosening.

[0050] For example, the first clamping part 320 and the second clamping part 420 are clamped and assembled, the second end of the locking member 500 is connected with the first assembly part 310, and the connection mode of the locking member 500 and the first assembly part 310 can include various detachable assembly modes such as clamping assembly and threaded connection assembly, which is not limited herein. At this time, the first end of the locking member 500 abuts against the clamped part of the first clamping part 320 and the second clamping part 420, and based on the abutment of the locking member 500 against the first clamping part 320 and the second clamping part 420, a stable relative clamping assembly between the first clamping part 320 and the second clamping part 420 can be formed, so as to avoid the relative clamping of the first clamping part 320 and the second clamping part 420 from being separated from each other.

[0051] Referring to the details shown in FIG. 6, the photovoltaic module can include a first frame member 1000 and a second frame member 2000. The first frame member 1000 includes a first frame body 1100, a supporting portion 1200 disposed on the first frame body 1100, and a waterproof portion 1300 disposed on the first frame body 1100. The supporting portion 1200 is disposed on a top portion of the first frame body 1100 and is configured to support the first long side 100a of the laminate 100. The waterproof portion 1300 is disposed on a bottom portion of the first frame body 1100. The top and bottom portions of the first frame body 1100 are shown in FIG. 7, but are not limited to the structural layout. The supporting portion 1200 can be configured to support the laminate 100, so that the laminate can be arranged in an inclined manner on a roof as shown in FIG. 4. Meanwhile, the waterproof portion 1300 can abut against the upper surface of another photovoltaic module when adjacent laminates 100 are connected, so as to protect the internal components such as the overlapping hanging member 300 and the overlapping support 400 from rain erosion, avoid rain backflow between the adjacent two photovoltaic modules in the direction of the roof slope, and play a sealing role to achieve waterproofing.

[0052] The second frame member 2000 includes a second frame body 2100, a first connecting portion 2200 disposed on the second frame body 2100, and a buffer portion 2300 disposed on the second frame body 2100. The first connecting portion 2200 is disposed on a top portion of the second frame body 2100 and is configured to connect the second long side 100b of the laminate 100. The buffer portion 2300 is disposed on a bottom portion of the second frame body 2100. The top and bottom portions of the second frame body 2100 are shown in FIG. 8, but are not limited to the structural layout. The first connecting portion 2200 can be configured to connect the laminate 100, so that when the laminate is arranged in an inclined manner on a roof as shown in FIG. 4, one side of the laminate is supported by the supporting portion 1200 and the other side is connected by the first connecting portion 2200. Meanwhile, the buffer portion 2300 is in contact with the cavity wall of the cavity chamber 600 of the overlapping support 400 as shown in FIG. 4, so as to achieve waterproofing, enhance friction, improve assembly stability, or buffer against the upper surface of another laminate 100 when adjacent laminates 100 are connected, so as to protect the assembly stability between the adjacent laminates 100.

[0053] Referring to FIGS. 6 and 7, in one embodiment, a first body passage 1100a can be formed in the first frame body 1100.

Specifically, a third connecting groove 4160a for receiving the side of the laminated member is formed by enclosing the fourth top frame plate body 4110, the third connecting vertical plate 4150, and the third connecting end plate 4160, thereby constructing the third connecting portion 4200 capable of connecting the side of the laminated member.

[0084] As shown in FIG. 9, the side of the laminated piece is inserted into the third connecting groove 4160a, which can be used to play the function of insertion fixation, and also can be filled with adhesive material with adhesive effect in the third connecting groove 4160a, to adhere and fix the side of the laminated piece in the third connecting groove 4160a. At this time, as shown in FIG. 11, the outer surface of the fourth top frame plate body 4110 can be provided with a third supporting protrusion 4160a3, which is located at the side of the fourth top frame plate body 4110 and is located in the third connecting groove 4160a. The third supporting protrusion 4160a3 can be used to support the lower surface of the laminated piece, and then the support of the laminated piece by the third supporting protrusion 4160a3 can form a certain gap in other areas of the outer surface of the fourth top frame plate body 4110, which is the gap between the outer surface of the fourth top frame plate body 4110 and the lower surface of the laminated piece. The gap can be used to accommodate adhesive material, so that the adhesive material can fully adhere the outer surface of the fourth top frame plate body 4110 and the lower surface of the laminated piece, fully adhere and fix the side of the laminated piece in the third connecting groove 4160a, prevent the weight of the laminated piece from extruding the adhesive material out, and cannot get sufficient adhesive amount, which cannot guarantee good adhesive effect. Therefore, the third supporting protrusion 4160a3 not only plays the supporting function, but also has the function of preventing the outflow of adhesive material.

[0085] In addition, the inner surface of the third connecting end plate 4160 is provided with a fifth positioning hook 4160a1 and a sixth positioning hook 4160a2, which are opposite in direction, and a third positioning gap is formed between the fifth positioning hook 4160a1 and the sixth positioning hook 4160a2. The fifth positioning hook 4160a1 and the sixth positioning hook 4160a2 can improve the stability of the insertion fixation of the laminated piece, and at the same time the third positioning gap also has the effect of filling and preventing the outflow of adhesive material, and also has the effect of fully filling the adhesive material in the third connecting groove 4160a and improving the stability of the adhesive.

[0086] In addition to the connection of adjacent photovoltaic modules by the sealing male part 3300 and the sealing female part 4300 and the connecting structure, the third frame body and the fourth frame body can also be used to connect with the cooperating cement tiles 700. For example, the connecting member can also include a first fitting 5000 and a second fitting 6000, and the connecting structure also includes a fifth plug-in protrusion 5000a provided on the first fitting 5000 and a sixth plug-in protrusion 6000a provided on the second fitting 6000. At this time, the third frame body can be provided with a third plug-in groove, and the fourth frame body can be provided with a fourth plug-in groove. Therefore, the first fitting 5000 can be plugged into the third plug-in groove through the fifth plug-in protrusion 5000a, thereby achieving the clamping assembly of the first fitting 5000 and the third frame body. The second fitting 6000 can be plugged into the fourth plug-in groove through the sixth plug-in protrusion 6000a, thereby achieving the clamping assembly of the second fitting 6000 and the fourth frame body. When the first fitting 5000 and the third frame body are clamped and assembled, the third frame body can be used to connect with the adjacent cement tile 700 through the first fitting 5000. When the second fitting 6000 and the fourth frame body are clamped and assembled, the fourth frame body can also be used to connect with the adjacent cement tile 700 through the second fitting 6000.

[0087] In order to enable the first fitting 5000 and the second fitting 6000 to be connected with the cement tile 700, the first fitting 5000 and the second fitting 6000 can be provided with a clamping structure that matches the structure of the end of the cement tile 700, so that the first fitting 5000 and the second fitting 6000 can be clamped and assembled with each other when connected with the cement tile 700 based on the matching clamping structure. For example, as shown in FIG. 12, different sizes and models of cement tiles 700 that need to be overlapped can be selected, and corresponding sizes and models of first fittings 5000 and second fittings 6000 can be selected according to different overlapping distances, thereby improving the flexibility of use of the cement tile 700, such as replacing first fittings 5000 and second fittings 6000 of different widths (in the direction of photovoltaic paving) to adapt to use. In some embodiments, the first fitting 5000 and the second fitting 6000 can be aluminum profiles, thereby having higher strength and lighter weight.

[0088] According to the embodiments of the present application, a photovoltaic power generation system can be provided, which can include the photovoltaic module described above. The number of the photovoltaic modules can be set to be multiple. The multiple photovoltaic modules are arranged along the second frame direction. Between two adjacent photovoltaic modules, the first frame member of one photovoltaic module is detachably connected with the overlapping hanging piece 300. The second frame member of the adjacent other photovoltaic module is connected with the overlapping support 400. The overlapping support 400 is provided with an accommodating cavity for accommodating the second frame member. The second frame member is arranged in the accommodating cavity of the overlapping support 400. The overlapping hanging piece 300 is connected with the overlapping support 400. The first frame member of one photovoltaic module is used to overlap the overlapping area of the adjacent other photovoltaic module, as shown in FIG. 4. In addition, the photovoltaic power generation system can further include a locking member 500. The locking member 500 is connected with the overlapping hanging piece 300, and the first end of the locking member 500 abuts against the connection position of the overlapping support 400 and the overlapping hanging piece 300, so as to lock the connection between the overlapping hanging piece 300 and the overlapping hanging piece 300.

[0089] For the specific structure and arrangement of the photovoltaic power generation system, the connection mode and arrangement mode of the multiple photovoltaic modules in the above embodiments can be referred to for understanding, which will not be repeated here.

[0090] In the photovoltaic module and the photovoltaic power generation system described above, the laminated piece can be used as a brand-new photovoltaic module product, which is directly used in the photovoltaic system. When assembling the tile roof, the brand-new photovoltaic module is directly used in the photovoltaic system, or the photovoltaic module arrangement structure cooperates with the overlapping hanging piece, the overlapping support and the locking member, so that the assembly work can be easily completed. When a certain photovoltaic module needs to be maintained, the photovoltaic module with problems can be directly disassembled, and then the same brand-new photovoltaic module is used as a replaceable unit product, which is assembled in the original position by cooperating with the overlapping hanging piece, the overlapping support and the locking member. The entire assembly process and maintenance process are in the form of unit replacement, which is convenient and efficient.
