Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, and more specifically, to a photovoltaic tile module and a rooftop photovoltaic system. Background Technology

[0002] Currently, photovoltaic (PV) power generation systems are installed on building roofs to save energy. However, the crystalline silicon photovoltaic modules in these systems have a planar structure, which differs significantly from the curved shape of traditional building roof tiles and cannot meet the requirements of architectural design.

[0003] To meet architectural design requirements, thin-film curved photovoltaic tiles are typically used. These tiles have a corrugated structure with crests and troughs. In thin-film curved photovoltaic tiles, both the thin-film photovoltaic modules and the glass are curved, resulting in greater production difficulty and higher production costs.

[0004] In conclusion, how to design photovoltaic tiles to reduce production difficulty and costs is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0116] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0117] like Figure 1aAs shown, the photovoltaic tile module provided in this embodiment includes: a first end frame 1, a second end frame 2, and a photovoltaic tile 3. The photovoltaic tile 3 includes at least two photovoltaic cell modules 301 and at least one connecting frame 302. Two adjacent photovoltaic cell modules 301 are connected by the connecting frame 302, and the photovoltaic cell modules 301 are flat.

[0118] Photovoltaic tile 3 has a waveform structure. For example... Figure 1a As shown, the waveform structure can be a curved waveform; for example... Figure 26 As shown, the waveform structure can also be a straight line. To improve aesthetics and meet architectural design requirements, a curved waveform structure can be selected.

[0119] Combination Figure 1a , Figure 1b and Figure 2 As shown, the photovoltaic tile 3 has horizontal, vertical, and height directions, with each pair of directions being perpendicular. In the height direction, the photovoltaic tile 3 has a top and a bottom; in the horizontal direction, the top and bottom of the photovoltaic tile 3 are alternately distributed; both the top and bottom of the photovoltaic tile 3 extend along the vertical direction.

[0120] The photovoltaic tile module also has a wave-like structure, meaning that the photovoltaic tile module and photovoltaic tile 3 have roughly the same shape. It can be understood that the horizontal direction of photovoltaic tile 3 is the same as the horizontal direction of the photovoltaic tile module, the vertical direction of photovoltaic tile 3 is the same as the vertical direction of the photovoltaic tile module, and the height direction of photovoltaic tile 3 is the same as the height direction of the photovoltaic tile module. In the height direction, the photovoltaic tile module also has a top and a bottom. In the horizontal direction, the top and bottom of the photovoltaic tile module are alternately distributed. The top of the photovoltaic tile module extends longitudinally, and the bottom of the photovoltaic tile module also extends longitudinally.

[0121] It should be noted that the above descriptions of "horizontal", "vertical", "height direction", "top", and "bottom" apply to all embodiments provided in this application. The "top" and "bottom" mentioned herein refer to the top and bottom in the height direction.

[0122] In two adjacent photovoltaic cell modules 301, one end of one photovoltaic cell module 301 and one end of the other photovoltaic cell module 301 are connected by a connecting frame 302. It can be understood that the number of connecting frames 302 is less than the number of photovoltaic cell modules 301, and the difference between the number of photovoltaic cell modules 301 and the number of connecting frames 302 is one.

[0123] If there are two photovoltaic cell modules 301 in the aforementioned photovoltaic tile 3, then there is one connecting frame 302, which is located at the top or bottom of the photovoltaic tile module; if there are three photovoltaic cell modules 301 in the aforementioned photovoltaic tile 3, then there are two connecting frames 302, one connected frame 302 located at the top of the photovoltaic tile module and the other connected frame 302 located at the bottom of the photovoltaic tile module; if there are four photovoltaic cell modules 301 in the aforementioned photovoltaic tile 3, then there are three connecting frames 302, two connected frames 302 located at the top of the photovoltaic tile module and the other connected frame 302 located at the bottom of the photovoltaic tile module, or two connected frames 302 located at the top of the photovoltaic tile module and the other connected frame 302 located at the bottom of the photovoltaic tile module. If there are five photovoltaic cell modules 301 in the photovoltaic tile 3, then there are four connecting frames 302, with two connecting frames 302 located at the top of the photovoltaic tile module and the other two connecting frames 302 located at the bottom of the photovoltaic tile module. If there are six photovoltaic cell modules 301 in the photovoltaic tile 3, then there are five connecting frames 302, with two connecting frames 302 located at the top of the photovoltaic tile module and the other three connecting frames 302 located at the bottom of the photovoltaic tile module, or two connecting frames 302 located at the bottom of the photovoltaic tile module and the other three connecting frames 302 located at the top of the photovoltaic tile module. If the number of photovoltaic cell modules 301 in the photovoltaic tile 3 is other than that, then the same logic applies, which will not be elaborated further in this article.

[0124] In practice, the number of photovoltaic cell modules 301 and connecting frame 302 may be selected as needed, and this embodiment does not limit this.

[0125] In the photovoltaic tile module, one end of the photovoltaic tile 3 is connected to the first end frame 1 in the horizontal direction, and the other end of the photovoltaic tile 3 is connected to the second end frame 2 in the horizontal direction. The first end frame 1 can be adapted to the second end frame 2.

[0126] It is understandable that, horizontally, the first end frame 1, the photovoltaic tile 3, and the second end frame 2 are connected sequentially. The first end frame 1, the photovoltaic tile 3, and the second end frame 2 form a wave-like structure to meet the requirements of the building's design.

[0127] The first end frame 1 can be adapted to the second end frame 2, which means that the first end frame 1 of a photovoltaic tile module is used to connect with the second end frame 2 of another photovoltaic tile module, and the second end frame 2 of a photovoltaic tile module is used to connect with the first end frame 1 of another photovoltaic tile module.

[0128] In the aforementioned photovoltaic tile assembly, one end of the first end frame 1 is connected to one end of the photovoltaic tile 3, and the other end of the first end frame 1 is used to connect to the second end frame 2 of another photovoltaic tile assembly; one end of the second end frame 2 is used to connect to the other end of the photovoltaic tile 3, and the other end of the second end frame 2 is used to connect to the first end frame 1 of another photovoltaic tile assembly.

[0129] In the aforementioned photovoltaic tile module, at least one connecting frame 302 is located at the top of the photovoltaic tile module, and / or at least one connecting frame 302 is located at the bottom of the photovoltaic tile module, and both the first end frame 1 and the second end frame 2 are located at the top or bottom of the photovoltaic tile module.

[0130] It should be noted that the first end frame 1, the photovoltaic tile 3, and the second end frame 2 form a waveform structure. This waveform structure has peaks and troughs. The peaks are the top in the height direction, and the troughs are the bottom in the height direction.

[0131] The photovoltaic tile module provided in the above embodiment connects the flat photovoltaic cell module 301 into a waveform structure through the first end frame 1, the connecting frame 302 and the second end frame 2, which meets the requirements of building design.

[0132] The photovoltaic tile module provided in the above embodiment is composed of a first end frame 1, a connecting frame 302, a second end frame 2, and a photovoltaic cell module 301 connected together. Since the photovoltaic cell module 301 is flat, only the first end frame 1, the second end frame 2, and the connecting frame 302 need to be bent or folded, without the photovoltaic cell module 301 needing to be bent or folded, which effectively reduces the production difficulty and production cost.

[0133] Furthermore, in the photovoltaic tile modules provided in the above embodiments, each photovoltaic tile 3 has end frames at both ends, namely a first end frame 1 and a second end frame 2. In the process of connecting two photovoltaic tile modules, the first end frame 1 of one photovoltaic tile module and the second end frame 2 of the other photovoltaic tile module can be directly connected, or the second end frame 2 of one photovoltaic tile module and the first end frame 1 of the other photovoltaic tile module can be directly connected. In this way, there is no connection step of photovoltaic cell module 301 in the connection process, so there is no need to consider the sealing problem, which simplifies the connection and laying of photovoltaic tile modules and also simplifies the replacement of damaged photovoltaic tile modules. At the same time, the first end frame 1 and the second end frame 2 are both located at the top or bottom of the photovoltaic tile module, which further simplifies the connection, laying and replacement of photovoltaic tile modules. Since the connection and laying of photovoltaic tile modules are simplified, at least two of the above photovoltaic tile modules can be pre-assembled before leaving the factory or assembled on site, which improves the cost-effectiveness of construction.

[0134] In the aforementioned photovoltaic tile assembly, the photovoltaic cell module 301 is flat and located between the top and bottom of the photovoltaic tile 3. This indicates that there is an obtuse angle between adjacent photovoltaic cell modules 301. After the photovoltaic tile assembly is installed, the horizontal direction of the photovoltaic tile 3 is east-west. In this way, in the morning, sunlight shines from the east and can directly illuminate several photovoltaic cell modules 301; in the afternoon, sunlight shines from the west and can also directly illuminate several photovoltaic cell modules 301. This achieves east-west reception of sunlight, reduces the difference between peak and valley power generation, makes the photovoltaic power generation curve smoother, and reduces the impact on the power grid.

[0135] In the aforementioned photovoltaic (PV) tile modules, the aforementioned PV cell module 301 can be a crystalline silicon PV cell module. For example, PV cell module 301 is a dual-wave PV module; this embodiment does not limit its type. The aforementioned PV cell module 301 may or may not have a module frame. This embodiment also does not limit this.

[0136] In the aforementioned photovoltaic tile 3, the connecting frame 302 includes a first connecting frame 302a and a second connecting frame 302b, which are fixedly connected to the photovoltaic cell module 301, respectively. Specifically, the first connecting frame 302a is fixedly connected to the photovoltaic cell module 301 adjacent to it, and the second connecting frame 302b is fixedly connected to the photovoltaic cell module 301 adjacent to it.

[0137] Specifically, one end of the first connecting frame 302a and one end of the second connecting frame 302b are connected, the other end of the first connecting frame 302a is fixedly connected to the photovoltaic cell module 301 adjacent to it, and the other end of the second connecting frame 302b is fixedly connected to the photovoltaic cell module 301 adjacent to it.

[0138] The first connecting frame 302a and the second connecting frame 302b can be an integrated structure or a separate structure, depending on the actual needs.

[0139] It is understood that if the first connecting frame 302a and the second connecting frame 302b are an integral structure, then the connecting frame 302 is a single component. If the first connecting frame 302a and the second connecting frame 302b are separate structures, then the connecting frame 302 is assembled from at least the first connecting frame 302a and the second connecting frame 302b. In some embodiments, such as Figures 1a-2 , Figure 5 , Figure 6 , Figure 26 and Figure 27As shown, the first connecting frame 302a and the second connecting frame 302b can be an integral structure. The connecting frame 302 has a flow guiding surface 11 or a flow collecting groove 12. In this way, the photovoltaic tile module has self-waterproof performance and extends its service life.

[0140] Specifically, the connecting frame 302 is located at the top of the photovoltaic tile module and has a flow guiding surface 11; the connecting frame 302 is located at the bottom of the photovoltaic tile module and has a flow collecting groove 12.

[0141] In some embodiments, the first connecting frame 302a and the second connecting frame 302b are separate structures, and the first connecting frame 302a and the second connecting frame 302b can be directly connected or indirectly connected.

[0142] The direct connection methods mentioned above can include overlapping or butt joints, etc. For ease of connection, such as... Figure 15 and Figure 16 As shown, the first connecting frame 302a and the second connecting frame 302b can be directly connected by overlapping. Specifically, the first connecting frame 302a includes a first overlapping plate 101, and the second connecting frame 302b includes a second overlapping plate 201, which is used to overlap with the first overlapping plate 101.

[0143] It is understandable that, in the height direction of the photovoltaic power generation module, the first overlapping plate 101 and the second overlapping plate 201 are distributed in sequence, that is, in the height direction of the photovoltaic power generation module, one of the first overlapping plate 101 and the second overlapping plate 201 is located at the top and the other is located at the bottom.

[0144] To improve stability, the overlapping first connecting frame 302a and second connecting frame 302b are fixedly connected. This fixed connection can be achieved through snap-fit, magnetic attachment, or other methods. To simplify installation, the first connecting frame 302a and second connecting frame 302b can be fixedly connected via snap-fit.

[0145] The specific structure of the aforementioned snap-fit ​​connection can be selected based on actual needs. For ease of assembly and disassembly, an insert-type snap-fit ​​connection can be selected. The insertion direction of the insert-type snap-fit ​​connection can be selected based on actual needs; this embodiment does not limit this.

[0146] In the aforementioned photovoltaic tile modules, waterproofing is necessary to improve service life. To achieve waterproofing, either the first connecting frame 302a or the second connecting frame 302b can be equipped with a flow channel 12, and the first connecting frame 302a and the second connecting frame 302b form a flow guiding structure for guiding flow into the flow channel 12. In this way, the photovoltaic tile modules have self-waterproofing properties, extending their service life.

[0147] In the case where the first connecting frame 302a includes a first overlapping plate 101 and the second connecting frame 302b includes a second overlapping plate 201, and the second overlapping plate 201 is used to overlap with the first overlapping plate 101, it is possible that both the second overlapping plate 201 and the first overlapping plate 101 are located at the top of the manifold 12. In this way, the second overlapping plate 201 and the manifold 12 are relatively independent, and the first overlapping plate 101 and the manifold 12 are relatively independent. That is, the second overlapping plate 201 and the first overlapping plate 101 do not form a part of the manifold 12 or do not form the entire manifold 12.

[0148] The first connecting frame 302a includes a first overlapping plate 101, and the second connecting frame 302b includes a second overlapping plate 201. When the second overlapping plate 201 is used to overlap with the first overlapping plate 101, the second overlapping plate 201 or the first overlapping plate 101 can also be selected to form a portion of the manifold 12. For example, the second overlapping plate 201 or the first overlapping plate 101 forms the bottom of the manifold 12.

[0149] In some embodiments, for the purpose of facilitating indirect connection, such as Figure 10 , Figure 11 , Figure 20 , Figure 21 , Figure 31 and Figure 32 As shown, the photovoltaic tile module can also include a first connecting member 13a; wherein the first connecting frame 302a and the second connecting frame 302b are indirectly connected through the first connecting member 13a.

[0150] In the above embodiments, to simplify the structure, the first connecting frame 302a and the second connecting frame 302b can be made to have identical structures. It is understood that the first connecting frame 302a and the second connecting frame 302b are completely identical, and their positions can be interchanged. This way, during the assembly of the first connecting frame 302a and the photovoltaic cell module 301, and during the assembly of the second connecting frame 302b and the photovoltaic cell module 301, it is not necessary to distinguish the positions of the first connecting frame 302a and the second connecting frame 302b, further simplifying the installation.

[0151] To improve waterproof performance, the first connecting frame 302a, the first connecting member 13a, and the second connecting frame 302b form a flow guiding surface 11; or, the first connecting frame 302a, the first connecting member 13a, and the second connecting frame 302b form a confluence channel 12.

[0152] Specifically, the first connecting frame 302a and the second connecting frame 302b are both located at the top of the photovoltaic tile module, and the first connecting frame 302a, the first connecting member 13a and the second connecting frame 302b form a flow guiding surface 11; the first connecting frame 302a and the second connecting frame 302b are both located at the bottom of the photovoltaic tile 3, and the first connecting frame 302a, the first connecting member 13a and the second connecting frame 302b form a confluence channel 12.

[0153] In the above embodiments, the connection structures between the first connecting frame 302a and the first connecting member 13a, and between the second connecting frame 302b and the first connecting member 13a, are selected according to actual needs. To simplify the connection, both the first connecting frame 302a and the second connecting frame 302b are snapped into the first connecting member 13a. For easier snapping, an insert-type snap-fit ​​structure can be selected.

[0154] The specific structure of the snap-fit ​​connection can be selected according to actual needs; this embodiment does not limit this.

[0155] In the aforementioned photovoltaic tile module, the connection between the adapted first end frame 1 and the second end frame 2 can be referenced to the connection between the first connecting frame 302a and the second connecting frame 302b. In some embodiments, the adapted first end frame 1 and the second end frame 2 can be directly connected. The direct connection method can be overlapping or butt jointing, etc. To facilitate connection, the adapted first end frame 1 and the second end frame 2 can be directly connected by overlapping. For example... Figure 3 , Figure 12 , Figure 17 , Figure 22 , Figure 28 and Figure 33 As shown, the first end frame 1 includes a first overlapping plate 101, and the second end frame 2 includes a second overlapping plate 201. The second overlapping plate 201 overlaps with the first overlapping plate 101 that is adapted to it. It can be understood that, in the height direction of the photovoltaic power generation module, the first overlapping plate 101 and the second overlapping plate 201 are distributed sequentially, that is, in the height direction of the photovoltaic power generation module, one of the first overlapping plate 101 and the second overlapping plate 201 is located at the top and the other is located at the bottom.

[0156] To improve stability, the overlapping first end frame 1 and the second end frame 2 are fixedly connected.

[0157] The aforementioned fixed connection can be achieved through snap-fit, magnetic attachment, or other methods. To simplify installation, the overlapping first end frame 1 and second end frame 2 are fixedly connected by snap-fit.

[0158] The specific structure of the aforementioned snap-fit ​​connection can be selected based on actual needs. For ease of assembly and disassembly, an insert-type snap-fit ​​connection can be selected. The insertion direction of the insert-type snap-fit ​​connection can be selected based on actual needs; this embodiment does not limit this.

[0159] Specifically, in the first end frame 1 and the second end frame 2 of the adapter, one is provided with a snap-fit ​​component, and the other is provided with a snap-fit ​​groove 10 for inserting into the snap-fit ​​component.

[0160] The specific structure of the snap-fit ​​connector and snap-fit ​​slot 10 can be selected according to actual needs, and this embodiment does not limit it.

[0161] To extend service life, waterproofing needs to be considered. On the one hand, such as... Figure 12 , Figure 17 and Figure 22 As shown, to achieve waterproofing, either the first end frame 1 or the second end frame 2 can be equipped with a flow channel 12, and the first end frame 1 and the second end frame 2 form a flow guiding structure for guiding flow to the flow channel 12. In this way, the photovoltaic power generation module has self-waterproofing performance, extending its service life.

[0162] The specific structure of the manifold 12 and the specific structure of the flow guiding structure can be selected according to actual needs, and this embodiment does not limit them.

[0163] The first end frame 1 includes a first overlapping plate 101, and the second end frame 2 includes a second overlapping plate 201. When the second overlapping plate 201 overlaps with the first overlapping plate 101, it is possible that both the second overlapping plate 201 and the first overlapping plate 101 are located on the top of the manifold 12. In this way, the second overlapping plate 201 and the manifold 12 are relatively independent, and the first overlapping plate 101 and the manifold 12 are relatively independent. That is, the second overlapping plate 201 and the first overlapping plate 101 do not form a part of the manifold 12 or do not form the entire manifold 12.

[0164] The first end frame 1 includes a first overlapping plate 101, and the second end frame 2 includes a second overlapping plate 201. When the second overlapping plate 201 is used to overlap with the first overlapping plate 101, the second overlapping plate 201 or the first overlapping plate 101 can also be selected to form a portion of the manifold 12. For example, the second overlapping plate 201 or the first overlapping plate 101 forms the bottom of the manifold 12.

[0165] In some embodiments, to improve waterproof performance, such as Figure 3 As shown, the first end frame 1 is provided with a first guide surface 102, and the second end frame 2 is provided with a second guide surface 202. In this case, both the first end frame 1 and the second end frame 2 are located on top of the photovoltaic tile module. This gives the photovoltaic tile module self-waterproofing properties and extends its service life.

[0166] like Figure 3 As shown, one end of the second guide surface 202 at the top is used to guide the flow to the lateral side of the top of the photovoltaic tile 3, and the other end of the second guide surface 202 at the top and the first guide surface 102 at the bottom are used to guide the flow to the confluence channel 12 formed by the photovoltaic tile 3.

[0167] In one embodiment, the first end border 1 and the second end border 2 of the adapter are indirectly connected.

[0168] For the purpose of facilitating indirect connections, such as Figure 28 and Figure 33 As shown, the photovoltaic tile module also includes a second connecting member 13b; wherein the first end frame 1 and the second end frame 2 are indirectly connected through the second connecting member 13b.

[0169] In the above embodiments, to simplify the structure, the first end frame 1 and the second end frame 2 can be made to have the same structure. It is understood that the first end frame 1 and the second end frame 2 are completely identical, and their positions can be interchanged. In this way, during the assembly of the first end frame 1 and the photovoltaic cell module 301, and the assembly of the second end frame 2 and the photovoltaic cell module 301, it is not necessary to distinguish the positions of the first end frame 1 and the second end frame 2, which further simplifies the installation.

[0170] To improve waterproof performance, the first end frame 1, the second connecting member 13b and the second end frame 2 form a flow guiding surface 11; or, the first end frame 1, the second connecting member 13b and the second end frame 2 form a confluence channel 12.

[0171] Specifically, the first end frame 1 and the second end frame 2 are both located on the top of the photovoltaic tile module, and the first end frame 1, the second connecting member 13b and the second end frame 2 form a flow guiding surface 11.

[0172] Specifically, the first end frame 1 and the second end frame 2 are both located at the bottom of the photovoltaic tile 3, and the first end frame 1, the second connecting member 13b and the second end frame 2 form a confluence channel 12.

[0173] In the above embodiments, the connection structures of the first end frame 1 and the second connecting member 13b, and the second end frame 2 and the second connecting member 13b, are selected according to actual needs. To simplify the connection, the second connecting member 13b is used to snap into the first end frame 1 that is adapted to it, and the second connecting member 13b is used to snap into the second end frame 2 that is adapted to it. For easy snap-in, an insert-type snap-in structure can be selected.

[0174] The specific structure of the snap-fit ​​connection can be selected according to actual needs; this embodiment does not limit this.

[0175] In the aforementioned photovoltaic tile module, the specific shapes of the connecting frame 302, the first end frame 1, and the second end frame 2 are selected according to actual needs. Specifically, the connecting frame 302, the first end frame 1, and the second end frame 2 are all curved or polygonal structures. To improve waterproof performance, the connecting frame 302, the first end frame 1, and the second end frame 2 can all be selected as curved structures.

[0176] It should be noted that if the connecting frame 302 is a curved structure, then both the first connecting frame 302a and the second connecting frame 302b are curved structures, and the waveform structure presented by the photovoltaic tile module is a curved waveform; if the connecting frame 302 is a broken line structure, then both the first connecting frame 302a and the second connecting frame 302b are broken line structures, and the waveform structure presented by the photovoltaic tile module is a straight line waveform.

[0177] It is understandable that a polygonal structure refers to a structure whose outer contour is formed by connecting several polygonal lines; a curved structure refers to a structure whose outer contour includes several curves.

[0178] In other embodiments, the connecting border 302, the first end border 1, and the second end border 2 may be selected to have other structures, such as curved structures and polyline structures; or the connecting border 302 may be a curved structure, in which case the first connecting border 302a and the second connecting border 302b may both be polyline structures; or the connecting border 302 may be a polyline structure, in which case the first connecting border 302a and the second connecting border 302b may both be curved structures. This embodiment does not limit this.

[0179] In the aforementioned photovoltaic tile module, the materials of the connecting frame 302, the first end frame 1, and the second end frame 2 are selected according to actual needs. Specifically, the connecting frame 302, the first end frame 1, and the second end frame 2 are all made of aluminum alloy, alloy steel, or plastic.

[0180] In practical applications, the connecting frame 302, the first end frame 1, and the second end frame 2 can all be made of alloy steel, which has a simple structure. Specifically, the connecting frame 302, the first end frame 1, and the second end frame 2 are all made of zinc-aluminum-magnesium steel.

[0181] In the aforementioned photovoltaic tile module, the connecting frame 302, the first end frame 1, and the second end frame 2 all need to be connected to the photovoltaic cell module 301. In order to facilitate the connection of the photovoltaic cell module 301, the connecting frame 302, the first end frame 1, and the second end frame 2 all have module slots 8 for the photovoltaic cell module 301 to be inserted.

[0182] To ensure performance, the aforementioned connecting frame 302, the first end frame 1, and the second end frame 2 are required to be fixedly and sealed to the photovoltaic cell module 301.

[0183] To facilitate sealing and fixing, the photovoltaic cell module 301 can be fixed to the module slot 8 with solid adhesive; the module slot 8 can also clamp the photovoltaic cell module 301 with its internal sealing strip 18; or the module slot 8 can clamp the photovoltaic cell module 301 with its internal sealing strip 18, and the photovoltaic cell module 301, the sealing strip 18 and the module slot 8 can be clamped and fixed with fasteners.

[0184] The aforementioned fixation adhesive can be silicone structural adhesive or other types, and this embodiment does not limit this.

[0185] To improve sealing reliability, the sealing strip 18 can be U-shaped. This can protect the pressure-bearing parts of the photovoltaic module 301 from damage and prevent rainwater from entering the module frame of the photovoltaic module 301.

[0186] Compared with existing liquid adhesive bonding methods, the above-mentioned sealing structure saves more materials, does not overflow adhesive, and has a cleaner and neater surface.

[0187] In practical applications, other methods can also be used to achieve fixed and sealed connections, and the above-described implementation methods are not the only options.

[0188] like Figures 36-38 As shown, the aforementioned photovoltaic tile modules are installed on the roof and need to be fixed to the roof purlins 28. For ease of fixing, as... Figure 1b As shown, the photovoltaic tile module also includes: a top frame 4 and / or a bottom frame 5.

[0189] The aforementioned top frame 4 is disposed on the top edge of the photovoltaic cell module 301 in the longitudinal direction, and the first end frame 1 and the second end frame 2 are both fixedly connected to the top frame 4; the aforementioned bottom frame 5 is disposed on the bottom edge of the photovoltaic cell module 301 in the longitudinal direction, and the first end frame 1 and the second end frame 2 are both fixedly connected to the bottom frame 5.

[0190] It should be noted that the top frame 4 is located between the first end frame 1 and the second end frame 2, and the bottom frame 5 is located between the first end frame 1 and the second end frame 2. The top edge of the photovoltaic cell module 301 refers to the side of the photovoltaic cell module 301 that is closer to the higher side of the sloping roof, and the bottom edge of the photovoltaic cell module 301 refers to the side of the photovoltaic cell module 301 that is closer to the lower side of the sloping roof.

[0191] like Figures 36-38 As shown, the slope of the sloping roof is consistent with the slope of the roof support beam 27. The roof purlins 28 are fixed to the roof support beam 27.

[0192] The connection methods of the first end border 1 and the bottom border 5, the second end border 2 and the bottom border 5, the first end border 1 and the top border 4, and the second end border 2 and the top border 4 can be selected according to actual needs. For example, the above connection methods can be connected by corner brackets, etc. This embodiment does not limit this.

[0193] If the photovoltaic tile assembly includes a top frame 4, the top frame 4 is used to fix it to the roof purlin 28; if the photovoltaic tile assembly includes a bottom frame 5, the bottom frame 5 is used to fix it to the roof purlin 28; if the photovoltaic tile assembly includes a top frame 4 and a bottom frame 5, the top frame 4 and / or the bottom frame 5 are used to fix it to the roof purlin 28.

[0194] For the fixed connection between the top frame 4 and the roof purlin 28, and the fixed connection between the bottom frame 5 and the roof purlin 28, bonding, welding or fastening with fasteners such as self-tapping screws 6 can be selected.

[0195] If the top frame 4 and / or the bottom frame 5 are used for fixed connection with the roof purlin 28 by fasteners, the fasteners can be set at the bottom of the photovoltaic tile module in the height direction for easy fixing.

[0196] To illustrate the technical solution provided by the present invention in more detail, six embodiments are provided below.

[0197] Example 1

[0198] like Figure 1b and Figure 2 As shown, the photovoltaic tile module provided in this embodiment includes: a first end frame 1, a second end frame 2, a top frame 4, a bottom frame 5, and a photovoltaic tile 3. The photovoltaic tile 3 includes eight photovoltaic cell modules 301 and three connecting frames 302. Four photovoltaic cell modules 301 are arranged sequentially in the horizontal direction, and two photovoltaic cell modules 301 are arranged sequentially in the vertical direction. The connecting frames 302 are an integral structure, with both the first end frame 1 and the second end frame 2 located at the top of the photovoltaic tile module.

[0199] In this first embodiment, as Figure 1a As shown, the photovoltaic tile module may not include the top frame 4 and the bottom frame 5.

[0200] The first end frame 1 is located at the left end of the photovoltaic tile 3 in the horizontal direction, the second end frame 2 is located at the right end of the photovoltaic tile 3 in the horizontal direction, the top frame 4 is located at the top edge of the photovoltaic tile 3 in the vertical direction, and the bottom frame 5 is located at the bottom edge of the photovoltaic tile 3 in the vertical direction. The top ends of the first end frame 1 and the second end frame 2 are fixedly connected to the top frame 4, and the bottom ends of the first end frame 1 and the second end frame 2 are fixedly connected to the bottom frame 5.

[0201] like Figure 1b , Figure 7 and Figure 8 As shown, the top frame 4 is fixedly connected to the roof purlins by self-tapping screws 6. During construction, the self-tapping screws 6 are connected to the roof purlins using an electric drill, with all self-tapping screws 6 located in the troughs.

[0202] To facilitate installation, the first end frame 1, the second end frame 2, the top frame 4, and the bottom frame 5 are all provided with support parts 7 to ensure the installation position of the photovoltaic tile module.

[0203] The first end frame 1, the second end frame 2, the top frame 4 and the bottom frame 5 are all provided with component slots 8. The component slots 8 are filled with silicone sealant. The component slots 8 and the photovoltaic cell module 301 are sealed and fixedly connected by the silicone sealant, which has good waterproof performance.

[0204] like Figure 2 As shown, the first end frame 1, the second end frame 2, and the connecting frame 302 connect the photovoltaic cell module 301 into a waveform structure with peaks and troughs. The first end frame 1 and the second end frame 2 are both located at the peaks, i.e., the top of the photovoltaic tile module; one connecting frame 302 is located at the peak, i.e., the top of the photovoltaic tile module; and the other two connecting frames 302 are located at the troughs, i.e., the bottom of the photovoltaic tile module.

[0205] like Figure 3 As shown, the adapted first end frame 1 and second end frame 2 overlap and snap together. Specifically, the first end frame 1 is provided with a first overlapping plate 101, and the second end frame 2 is provided with a second overlapping plate 201. In the adapted first end frame 1 and second end frame 2, the second overlapping plate 201 overlaps the top of the first overlapping plate 101.

[0206] The top surface of the first end frame 1 is a first flow guiding surface 102, and the top surface of the second end frame 2 is a second flow guiding surface 202. The left end of the second flow guiding surface 202 is used to guide flow to the left side of the top of the photovoltaic tile module, that is, to the flow channel 12 formed by the photovoltaic tile 3; the right end of the second flow guiding surface 202 and the first flow guiding surface 102 are used to guide flow to the right side of the top of the photovoltaic tile module, that is, to the flow channel 12 formed by another photovoltaic tile 3.

[0207] The first overlapping plate 101 has a snap-fit ​​groove 10 at its top, and the second overlapping plate 201 has a first snap-fit ​​member 9 at its bottom. The first snap-fit ​​member 9 is used to insert into the snap-fit ​​groove 10, and the insertion direction is parallel to the height direction of the photovoltaic tile module. Figure 3 The direction in which the double-headed arrow is located.

[0208] like Figure 4 As shown, in order to improve the snap-fit ​​performance, the first snap-fit ​​component 9 includes a first snap-fit ​​component body 901 and a protrusion 902, the protrusion 902 protruding from the circumferential sidewall of the first snap-fit ​​component body 901.

[0209] The first snap-fit ​​component 9 can be plate-shaped or column-shaped, depending on the actual needs. The shape of the protrusion 902 can also be selected according to the actual needs. To improve stability, the surface of the protrusion 902 can be curved, and the curved surface protrudes in a direction away from the main body 901 of the first snap-fit ​​component.

[0210] The aforementioned protrusion 902 may be one or more. If the aforementioned protrusion 902 is two or more, at least two protrusions 902 may be selected and distributed sequentially along the axial direction of the first snap-fit ​​body 901, and / or at least two protrusions 902 may be distributed sequentially along the circumferential direction of the first snap-fit ​​body 901.

[0211] To facilitate the formation of the aforementioned snap-fit ​​groove 10, the snap-fit ​​groove 10 can be formed by two clamping members 1001. The clamping members 1001 can be columnar or plate-shaped, etc., and grooves are provided on opposite sides of the two clamping members 1001. These grooves are used to fit the aforementioned protrusions 902. The aforementioned grooves can be formed by protrusions on the clamping members 1001.

[0212] In practice, the first connector 9 and the connector slot 10 can also be other structures, and are not limited to these. Figure 3 and Figure 4 The structure shown.

[0213] To improve waterproofing, the first snap-fit ​​9 is located at the bottom of its component, and the snap-fit ​​groove 10 is located at the top of its component.

[0214] The first connector 9 mentioned above can be one or more, depending on actual needs. This embodiment does not limit this.

[0215] In the aforementioned first end frame 1 and second end frame 2, the positions of the first snap-fit ​​member 9 and the snap-fit ​​groove 10 can be interchanged; alternatively, the first overlapping plate 101 can overlap the top of the second overlapping plate 201, and it is not limited to this. Figure 3 The structure shown.

[0216] like Figure 5 and Figure 6As shown, the two ends of the connecting frame 302 are provided with component slots 8, the photovoltaic cell module 301 is inserted into the component slot 8, and the photovoltaic cell module 301 and the component slot 8 are sealed together.

[0217] like Figure 5 and Figure 6 As shown, the connecting frame 302 is a one-piece structure and is a curved structure. Figure 5 As shown, the connecting frame 302 located at the top of the photovoltaic tile 3 has a flow guiding surface 11; as Figure 6 As shown, the connecting frame 302 located at the bottom of the photovoltaic tile has a manifold 12. This gives the connecting frame 302 good waterproof performance and resistance to deformation.

[0218] In this embodiment, the structures of the first end frame 1 and the second end frame 2 are different. The first end frame 1 can be located at either the top or the bottom of the photovoltaic tile 3; correspondingly, the second end frame 2 can be located at either the top or the bottom of the photovoltaic tile 3, thus improving the installation flexibility of the first end frame 1 and the second end frame 2. It can be understood that both the first end frame 1 and the second end frame 2 are located at either the top or the bottom of the photovoltaic tile 3.

[0219] Other structures in this embodiment can be referred to the preceding text, and will not be repeated here.

[0220] Example 2

[0221] like Figure 9 and Figure 10 As shown, the photovoltaic tile module provided in this embodiment includes: a first end frame 1, a second end frame 2, a top frame 4, a bottom frame 5, and a photovoltaic tile 3. The photovoltaic tile 3 includes four photovoltaic cell modules 301 and a connecting frame 302. Two photovoltaic cell modules 301 are sequentially distributed horizontally and two photovoltaic cell modules 301 are sequentially distributed vertically.

[0222] In this second embodiment, the photovoltaic tile module may not include the top frame 4 and the bottom frame 5.

[0223] The first end frame 1, the second end frame 2 and the connecting frame 302 connect the photovoltaic cell module 301 into a waveform structure with peaks and troughs; the first end frame 1 and the second end frame 2 are both located at the peaks, that is, the top of the photovoltaic tile module; the connecting frame 302 is located at the troughs, that is, the bottom of the photovoltaic tile module.

[0224] The distribution of the first end border 1, the second end border 2, the top border 4, and the bottom border 5 can be referred to in Embodiment 1.

[0225] like Figure 9 and Figure 13As shown, the top frame 4 is fixedly connected to the roof purlins by self-tapping screws 6. During construction, the self-tapping screws 6 are connected to the roof purlins using an electric drill, with all self-tapping screws 6 located in the troughs.

[0226] The first end frame 1, the second end frame 2, the top frame 4 and the bottom frame 5 are all provided with component slots 8. A U-shaped sealing strip 18 is provided inside the component slot 8. The component slot 8 and the photovoltaic cell module 301 are sealed and fixedly connected through the sealing strip 18, which has good waterproof performance.

[0227] like Figure 10 and Figure 11 As shown, the connecting frame 302 includes a first connecting frame 302a and a second connecting frame 302b. The first connecting frame 302a and the second connecting frame 302b are separate structures, and the first connecting frame 302a and the second connecting frame 302b are connected by a first connecting member 13a.

[0228] like Figure 11 As shown, the first connecting frame 302a has a first slot 14 at both its top and bottom, the second connecting frame 302b has a second slot 15 at both its top and bottom, and the first connecting member 13a has a first clip 16 and a second clip 17. The first clip 16 is used to insert into the first slot 14, and the second clip 17 is used to insert into the second slot 15. It can be understood that the first clip 16 is located at the top and bottom of the first connecting member 13a, and the second clip 17 is located at the top and bottom of the first connecting member 13a.

[0229] To improve snap-fit ​​stability, the first slot 14 tapers from its bottom to its opening, and the second slot 15 also tapers from its bottom to its opening. It is understood that the shape of the first locking member 16 is adapted to the first slot 14, and the shape of the second locking member 17 is adapted to the shape of the second slot 15. Of course, the first slot 14 and the second slot 15 can also be chosen to have other shapes; this embodiment does not limit this.

[0230] It should be noted that both the first card 16 and the second card 17 are card components, and both the first card slot 14 and the second card slot 15 are card slots.

[0231] In this embodiment, alternatively, the top of the first connecting frame 302a may be provided with a first slot 14, and the top of each of the second connecting frames 302b may be provided with a second slot 15. The first connecting member 13a may be provided with a first latch 16 and a second latch 17. The first latch 16 is used for inserting into the first slot 14, and the second latch 17 is used for inserting into the second slot 15. It can be understood that the first latch 16 is located on the top of the first connecting member 13a, and the second latch 17 is located on the top of the first connecting member 13a.

[0232] In this embodiment, alternatively, the bottom of the first connecting frame 302a may be provided with a first slot 14, and the bottom of the second connecting frame 302b may be provided with a second slot 15. The first connecting member 13a may be provided with a first latch 16 and a second latch 17. The first latch 16 is used for inserting into the first slot 14, and the second latch 17 is used for inserting into the second slot 15. It can be understood that the first latch 16 is located at the bottom of the first connecting member 13a, and the second latch 17 is located at the bottom of the first connecting member 13a.

[0233] In this embodiment, the positions of the first card slot 14 and the first card piece 16 can be interchanged, and the positions of the second card slot 15 and the second card piece 17 can also be interchanged.

[0234] like Figure 12 As shown, the first end frame 1 and the second end frame 2 of the adapter only overlap. The first end frame 1 is provided with: a first frame body 103, a first overlapping plate 101 fixedly connected to the first frame body 103, and a busbar 12. The first frame body 103 and the photovoltaic cell module 301 are fixedly connected, and the first end frame 1 is an integral structure.

[0235] The second end frame 2 is provided with: a second frame body 203, a second overlapping plate 201 fixedly connected to the second frame body 203, and a reinforcing member 19. The top surface of the second overlapping plate 201 is a second flow guiding surface 202. The second frame body 203 and the photovoltaic cell module 301 are fixedly connected. The second end frame 2 is an integrated structure.

[0236] In the first end frame 1 and the second end frame 2, the second overlapping plate 201 overlaps the top of the first overlapping plate 101, and both the second overlapping plate 201 and the first overlapping plate 101 are located at the top of the confluence channel 12. There is a first gap 01 between the second overlapping plate 201 and the first frame body 103, and a second gap 02 between the second overlapping plate 201 and the first overlapping plate 101. The second guide surface 202, the first gap 01 and the second gap 02 form a guide structure for guiding flow into the confluence channel 12.

[0237] The aforementioned reinforcing member 19 is connected to the second overlapping plate 201, increasing the strength of the entire second end frame 2. A third gap 03 exists between the reinforcing member 19 and the first overlapping plate 101 to guide flow into the confluence channel 12. To increase the size of the confluence channel 12, a fourth gap 04 exists between the reinforcing member 19 and the bottom of the confluence channel 12.

[0238] In practice, the reinforcing member 19 can also be connected to the bottom of the manifold 12; alternatively, the second end frame 2 can be left without the reinforcing member 19, and is not limited to this option. Figure 12The structure shown.

[0239] In this embodiment, if the first overlapping plate 101 overlaps the top of the second overlapping plate 201, the reinforcing member 19 can be disposed on the first overlapping plate 101, and the manifold 12 can be disposed on the second overlapping plate 201.

[0240] In this embodiment, the first connecting frame 302a and the second connecting frame 302b have the same structure. The first connecting frame 302a can be located at either the top or the bottom of the photovoltaic module 301; correspondingly, the second connecting frame 302b can be located at either the top or the bottom of the photovoltaic module 301, thus improving the installation flexibility of the first connecting frame 302a and the second connecting frame 302b. It can be understood that both the first connecting frame 302a and the second connecting frame 302b are located at either the top or the bottom of the photovoltaic module 301.

[0241] In this embodiment, the first end frame 1 and the second end frame 2 have the same structure. The first end frame 1 can be located at either the top or the bottom of the photovoltaic tile 3; correspondingly, the second end frame 2 can be located at either the top or the bottom of the photovoltaic tile 3, thus improving the installation flexibility of the first end frame 1 and the second end frame 2. It can be understood that both the first end frame 1 and the second end frame 2 are located at either the top or the bottom of the photovoltaic tile 3.

[0242] Other structures in this second embodiment can be referred to in the previous description, and will not be repeated here.

[0243] Example 3

[0244] like Figures 14-18 As shown, the photovoltaic tile module provided in this embodiment 3 differs from that in embodiment 2 in that the structure of the connecting frame 302 is different.

[0245] like Figure 15 and Figure 16 As shown, the connecting frame 302 is located at the bottom of the photovoltaic tile module. The connecting frame 302 includes a first connecting frame 302a and a second connecting frame 302b. The first connecting frame 302a and the second connecting frame 302b are separate structures, and the first connecting frame 302a and the second connecting frame 302b only overlap.

[0246] The first connecting frame 302a includes a first frame body 103 and a first overlapping plate 101 that are fixedly connected, and the second connecting frame 302b includes a second frame body 203 and a second overlapping plate 201 that are fixedly connected. The first overlapping plate 101 is used to overlap with the second overlapping plate 201.

[0247] The first overlapping plate 101 overlaps the top of the second overlapping plate 201, and the second overlapping plate 201 forms part of the manifold 12. In order to facilitate the formation of the manifold 12, the second connecting frame 302b is provided with a baffle 20, and the second frame body 203, the second overlapping plate 201 and the baffle 20 form the manifold 12.

[0248] The first overlapping plate 101 is provided with a flow guide 21, and there is a fifth gap 05 between the flow guide 21 and the second frame body 203. The fifth gap 05 forms a flow guide structure for guiding the flow to the confluence channel 12.

[0249] Combination Figure 16 As shown, the first overlapping plate 101 is located on the left side of the baffle 20, and the manifold 12 is located on the right side of the baffle 20.

[0250] In practice, the first overlapping plate 101 can also be overlapped at the bottom of the second overlapping plate 201. The first overlapping plate 101 is provided with a baffle 20, and the first frame body 103, the first overlapping plate 101, and the baffle 20 form a confluence channel 12. The second overlapping plate 201 is provided with a guide member 21, which forms a flow guiding structure for guiding flow to the confluence channel 12. It is understood that there is a sixth gap between the guide member 21 and the first frame body 103, and this sixth gap communicates with the confluence channel 12.

[0251] In this third embodiment, Figure 17 The overlapping structure of the first end frame 1 and the second end frame 2 is shown. For details, please refer to Embodiment 2, which will not be repeated here.

[0252] In this embodiment, the first connecting frame 302a and the second connecting frame 302b have different structures. The first connecting frame 302a can be located at either the top or the bottom of the photovoltaic module 301; correspondingly, the second connecting frame 302b can be located at either the top or the bottom of the photovoltaic module 301, thus improving the installation flexibility of the first connecting frame 302a and the second connecting frame 302b. It can be understood that both the first connecting frame 302a and the second connecting frame 302b are located at either the top or the bottom of the photovoltaic module 301.

[0253] In this embodiment, the structures of the first end frame 1 and the second end frame 2 are different. The first end frame 1 can be located at either the top or the bottom of the photovoltaic tile 3; correspondingly, the second end frame 2 can be located at either the top or the bottom of the photovoltaic tile 3, thus improving the installation flexibility of the first end frame 1 and the second end frame 2. It can be understood that both the first end frame 1 and the second end frame 2 are located at either the top or the bottom of the photovoltaic tile 3.

[0254] In this third embodiment, the photovoltaic tile module may not include the top frame 4 and the bottom frame 5.

[0255] Other structures in this embodiment three can be referred to in the previous description, and will not be repeated here.

[0256] Example 4

[0257] like Figures 19-24 As shown, the main difference between this embodiment four and embodiment two is that the structures of the first end frame 1, the second end frame 2, and the connecting frame 302 are different.

[0258] like Figure 20 and Figure 21 As shown, the connecting frame 302 includes a first connecting frame 302a and a second connecting frame 302b. The first connecting frame 302a and the second connecting frame 302b are separate structures, and the first connecting frame 302a and the second connecting frame 302b are connected by a first connecting member 13a.

[0259] like Figure 21 As shown, the first connecting member 13a is provided with a first slot 1301 and a second slot 1302. The first connecting frame 302a is used for inserting into the first slot 1301, and the second connecting frame 302b is used for inserting into the second slot 1302. This simplifies the structure of the first connecting frame 302a, the second connecting frame 302b, and the first connecting member 13a, and also simplifies the installation.

[0260] like Figure 22 As shown, the first end frame 1 and the second end frame 2 of the adapter overlap and are inserted into each other.

[0261] The first end frame 1 is provided with: a first frame body 103, a first overlapping plate 101 fixedly connected to the first frame body 103, and a second snap-fit ​​member 22 disposed on the first overlapping plate 101, wherein a confluence groove 12 is formed between the second snap-fit ​​member 22, the first overlapping plate 101 and the first frame body 103. In this case, the first overlapping plate 101 forms a portion of the confluence groove 12.

[0262] The aforementioned second end frame 2 is provided with: a second frame body 203, a second overlapping plate 201 fixedly connected to the second frame body 203, and a snap-fit ​​groove 10 disposed on the second overlapping plate 201. A first gap 01 exists between the second overlapping plate 201 and the first frame body 103, and the first gap 01 communicates with the confluence channel 12. The top surface of the second overlapping plate 201 is a second flow guiding surface 202. The second flow guiding surface 202 and the first gap 01 form a flow guiding structure for guiding flow to the confluence channel 12. In this case, the snap-fit ​​groove 10 also serves to increase the strength of the second overlapping plate 201.

[0263] The second snap-fit ​​component 22 and the snap-fit ​​slot 10 are inserted into each other, with the insertion direction parallel to the height direction of the photovoltaic tile module. Figure 22 The direction of the double-headed arrow in the image.

[0264] The second snap-fit ​​component 22 includes two parallel snap-fit ​​plates 2201, with the two snap-fit ​​plates 2201 connected at one end near the snap-fit ​​groove 10. The snap-fit ​​groove 10 clamps the two snap-fit ​​plates 2201. Alternatively, the two snap-fit ​​plates 2201 can be inclined relative to each other, and the included angle between the two snap-fit ​​plates 2201 can be acute or obtuse, depending on the actual situation.

[0265] Of the two snap-fit ​​plates 2201, only one snap-fit ​​plate 2201 is connected to the first overlapping plate 101, while the other snap-fit ​​plate 2201 has a preset distance from the top surface of the first overlapping plate 101, meaning that the end of the other snap-fit ​​plate 2201 closest to the first overlapping plate 101 is suspended. This increases the elasticity of the entire second snap-fit ​​component 22 and improves the snap-fit ​​effect.

[0266] The aforementioned second connector 22 can be one or more, selected according to actual needs; this embodiment does not limit this. The number of connector slots 10 can be adaptively adjusted according to the number of second connectors 22; this embodiment also does not limit this.

[0267] To facilitate the formation of the aforementioned snap-fit ​​groove 10, the snap-fit ​​groove 10 may be formed by two clamping members 1001, which may be columnar or plate-shaped. To facilitate snap-fit, both sides of the two clamping members 1001 may be provided with protrusions, which are used to contact the matching snap-fit ​​plate 2201.

[0268] In practice, the aforementioned snap-fit ​​slot 10 and the second snap-fit ​​component 22 can be selected from other structures, and are not limited to these. Figure 22 The structure shown.

[0269] In this embodiment, the positions of the second snap-fit ​​member 22 and the snap-fit ​​groove 10 can be interchanged, and are not limited to the above structure.

[0270] Both the first overlapping plate 101 and the second overlapping plate 201 are overlapping plates. To improve waterproof performance, the second snap-fit ​​member 22 is located at the top of its overlapping plate, and the snap-fit ​​groove 10 is located at the bottom of its overlapping plate.

[0271] In this embodiment, the first connecting frame 302a and the second connecting frame 302b have the same structure. The first connecting frame 302a can be located at either the top or the bottom of the photovoltaic module 301; correspondingly, the second connecting frame 302b can be located at either the top or the bottom of the photovoltaic module 301, thus improving the installation flexibility of the first connecting frame 302a and the second connecting frame 302b. It can be understood that both the first connecting frame 302a and the second connecting frame 302b are located at either the top or the bottom of the photovoltaic module 301.

[0272] In this embodiment, the structures of the first end frame 1 and the second end frame 2 are different. The first end frame 1 can be located at either the top or the bottom of the photovoltaic tile 3; correspondingly, the second end frame 2 can be located at either the top or the bottom of the photovoltaic tile 3, thus improving the installation flexibility of the first end frame 1 and the second end frame 2. It can be understood that both the first end frame 1 and the second end frame 2 are located at either the top or the bottom of the photovoltaic tile 3.

[0273] like Figure 19 As shown, the photovoltaic tile module provided in this embodiment four does not have a bottom frame. To improve the stability of the photovoltaic tile module, as... Figure 19 and Figure 23 As shown, the first connecting member 13a is provided with a component connecting portion 1303 for fixed connection with the roof purlin. The component connecting portion 1303 can be fixed to the roof purlin by fasteners, welded to the roof purlin, or bonded to the roof purlin. To simplify assembly and disassembly, the component connecting portion 1303 is fixed to the roof purlin by self-tapping screws 6.

[0274] like Figure 24 As shown, the top frame 4 is fixedly connected to the roof purlin by self-tapping screws 6.

[0275] In this fourth embodiment, the connection method of the first end frame 1, the second end frame 2, the connecting frame 302, the top frame 4, and the photovoltaic cell module 301 can be referred to the previous text and will not be repeated here.

[0276] like Figure 19 As shown, the photovoltaic tile module does not have a bottom border. Of course, the photovoltaic tile module may also exclude the top border 4.

[0277] Other structures in this embodiment four can be referred to in the previous description, and will not be repeated here.

[0278] Example 5

[0279] like Figures 25-29As shown, the main difference between this fifth embodiment and the fourth embodiment is that the structures of the connecting frame 302, the first end frame 1, and the second end frame 2 are different.

[0280] like Figure 26 and Figure 27 As shown, the connecting frame 302 has a zigzag structure and is a one-piece structure. Module slots 8 are provided at both ends of the connecting frame 302, and the photovoltaic cell module 301 is inserted into the module slot 8, with the photovoltaic cell module 301 and the module slot 8 forming a sealed connection.

[0281] like Figure 27 As shown, the connecting frame 302 itself forms a confluence channel 12, which improves the waterproof performance of the entire structure.

[0282] like Figure 28 As shown, both the first end frame 1 and the second end frame 2 are polygonal structures. The first end frame 1 and the second end frame 2 are overlapped and snapped together by the second connecting member 13b. The first end frame 1, the second end frame 2, and the second connecting member 13b form a flow guide surface, which guides the flow to the left and right ends.

[0283] The second connecting member 13b is provided with an overlapping portion 1304 and a snap-fit ​​portion 1307 for fixed connection. The top of the first end frame 1 is provided with a first connecting portion, and the top of the second end frame 2 is provided with a second connecting portion; wherein, both the first connecting portion and the second connecting portion are snap-fitted with the snap-fit ​​portion 1307, and the overlapping portion 1304 overlaps on the same side of the first connecting portion and the second connecting portion.

[0284] It is understandable that one end of the overlapping portion 1304 overlaps with the first connecting portion, and the other end of the overlapping portion 1304 overlaps with the second connecting portion.

[0285] In practice, the first connecting part can also be located at the bottom of the first end frame 1, and the second connecting part can be located at the bottom of the second end frame 2; it is not limited to this. Figure 28 The structure shown.

[0286] For ease of installation, the first and second connecting parts that overlap with the same overlapping part 1304 can be located at the same height of the frame assembly.

[0287] The aforementioned overlapping portion 1304 may be an overlapping plate or other types, and this embodiment does not limit it.

[0288] The specific shapes of the first connecting part, the second connecting part, and the snap-fit ​​part 1307 are selected according to the actual situation.

[0289] like Figure 28As shown, the first connecting part includes a first connecting plate 23 and a first L-shaped clamping plate 24, with the long plate of the first L-shaped clamping plate 24 connected to the first connecting plate 23; the second connecting part includes a second connecting plate 25 and a second L-shaped clamping plate 26, with the long plate of the second L-shaped clamping plate 26 connected to the second connecting plate 25; both the first L-shaped clamping plate 24 and the second L-shaped clamping plate 26 are clamped to the clamping part 1307, and the short plates of both the first L-shaped clamping plate 24 and the second L-shaped clamping plate 26 are located within the clamping part 1307, with the overlapping part 1304 overlapping the tops of the first connecting plate 23 and the second connecting plate 25.

[0290] The aforementioned latching part 1307 has a third latching slot 1305 that latches with the first L-shaped latching plate 24 and a fourth latching slot 1306 that latches with the second L-shaped latching plate 26.

[0291] It is understandable that both the first L-shaped pallet 24 and the second L-shaped pallet 26 are L-shaped pallets. An L-shaped pallet consists of two vertically connected plates, one of which is longer and the other is shorter. Of course, it is also possible to choose two vertically connected plates of the L-shaped pallet that are of equal length. In this case, one of the plates is the longer plate and the other is the shorter plate.

[0292] For ease of connection, the long plate of the first L-shaped plate 24 and the first connecting plate 23 can be connected perpendicularly, and the long plate of the second L-shaped plate 26 and the second connecting plate 25 can be connected perpendicularly.

[0293] In this embodiment, both the first L-shaped card plate 24 and the second L-shaped card plate 26 may be provided with a card slot structure, and the card engaging part 1307 may have a structure that engages with the card slot structure; it is not limited to the above-described structure. In this embodiment, the first end frame 1 and the second end frame 2 have the same structure. The first end frame 1 can be located at either the top or the bottom of the photovoltaic tile 3; correspondingly, the second end frame 2 can be located at either the top or the bottom of the photovoltaic tile 3, thus improving the installation flexibility of the first end frame 1 and the second end frame 2. It can be understood that both the first end frame 1 and the second end frame 2 are located at either the top or the bottom of the photovoltaic tile 3.

[0294] like Figure 25 and Figure 29 As shown, to improve stability, the second connecting member 13b is provided with a component connecting portion 1303 for fixed connection with the roof purlin 28. The component connecting portion 1303 can be fixed to the roof purlin by fasteners, welded to the roof purlin, or bonded to the roof purlin. For ease of assembly and disassembly, the component connecting portion 1303 is fixed to the roof purlin by self-tapping screws 6.

[0295] like Figure 25As shown, the photovoltaic tile module does not have a bottom border. Of course, the photovoltaic tile module may also exclude the top border 4.

[0296] Other structures in this embodiment five can be referred to in the previous description, and will not be repeated here.

[0297] Example 6

[0298] like Figures 30-35 As shown, the main difference between this embodiment six and embodiment five is that the structures of the connecting frame 302, the first end frame 1, and the second end frame 2 are different.

[0299] like Figure 31 and Figure 32 As shown, the connecting frame 302 includes a first connecting frame 302a and a second connecting frame 302b. The first connecting frame 302a and the second connecting frame 302b are separate structures, and the first connecting frame 302a and the second connecting frame 302b are overlapped and snapped together by the first connecting member 13a.

[0300] In this embodiment, the first connecting frame 302a and the second connecting frame 302b have the same structure. The first connecting frame 302a can be located at either the top or the bottom of the photovoltaic tile 3; correspondingly, the second connecting frame 302b can be located at either the top or the bottom of the photovoltaic tile 3, thus improving the installation flexibility of the first connecting frame 302a and the second connecting frame 302b. It can be understood that both the first connecting frame 302a and the second connecting frame 302b are located at the top or bottom of the photovoltaic cell module 301.

[0301] like Figure 33 As shown, the first end frame 1 and the second end frame 2 of the adapter overlap and snap together through the second connecting member 13b.

[0302] In this embodiment, the first connecting frame 302a and the second connecting frame 302b have the same structure, the first end frame 1 and the second end frame 2 have the same structure, and the first connecting member 13a and the second connecting member 13b have the same structure.

[0303] like Figures 32-34As shown, the top and bottom of the first connecting frame 302a are provided with a first connecting part, which includes a first connecting plate 23 and a first L-shaped card plate 24. The long plate of the first L-shaped card plate 24 is connected to the first connecting plate 23. The top and bottom of the second connecting frame 302b are provided with a second connecting part, which includes a second connecting plate 25 and a second L-shaped card plate 26. The long plate of the second L-shaped card plate 26 is connected to the second connecting plate 25. The first end frame 1 is provided with a first connecting plate 23 and a first L-shaped card plate 24. The long plate of the first L-shaped card plate 24 is connected to the first connecting plate 23. The second end frame 2 is provided with a second connecting plate 25 and a second L-shaped card plate 26. The long plate of the second L-shaped card plate 26 is connected to the second connecting plate 25.

[0304] Both the first connecting member 13a and the second connecting member 13b are provided with a fixedly connected overlapping portion 1304 and a snap-fit ​​portion 1307. Both the first connecting portion and the second connecting portion snap-fit ​​with the snap-fit ​​portion 1307, and both the first connecting portion and the second connecting portion overlap with the overlapping portion 1304. Specifically, both the first L-shaped snap-fit ​​plate 24 and the second L-shaped snap-fit ​​plate 26 snap-fit ​​with the snap-fit ​​portion 1307, and the short sides of both the first L-shaped snap-fit ​​plate 24 and the second L-shaped snap-fit ​​plate 26 are located within the snap-fit ​​portion 1307. The overlapping portion 1304 overlaps on the same side of the first connecting plate 23 and the second connecting plate 25.

[0305] It is understood that the aforementioned latching part 1307 has a third latching slot 1305 that latches with the first L-shaped latching plate 24 and a fourth latching slot 1306 that latches with the second L-shaped latching plate 26.

[0306] In each first connecting member 13a and each second connecting member 13b, there are two overlapping portions 1304 and two snap-fit ​​portions 1307. In the height direction, one overlapping portion 1304, one snap-fit ​​portion 1307, another snap-fit ​​portion 1307, and another overlapping portion 1304 are connected sequentially. Correspondingly, in the first connecting frame 302a, there are two first connecting plates 23 and two first L-shaped snap-fit ​​plates 24. The first connecting plates 23 correspond one-to-one with the overlapping portions 1304, and the first L-shaped snap-fit ​​plates 24 correspond one-to-one with the snap-fit ​​portions 1307. In the second connecting frame 302b, there are two second connecting plates 25 and two second L-shaped snap-fit ​​plates 26. The second connecting plates 25 correspond one-to-one with the overlapping portions 1304, and the second L-shaped snap-fit ​​plates 26 correspond one-to-one with the snap-fit ​​portions 1307.

[0307] It is understandable that both the first L-shaped pallet 24 and the second L-shaped pallet 26 are L-shaped pallets. An L-shaped pallet consists of two vertically connected plates, one of which is longer and the other is shorter. Of course, it is also possible to choose two vertically connected plates of the L-shaped pallet that are of equal length. In this case, one of the plates is the longer plate and the other is the shorter plate.

[0308] For ease of connection, the long plate of the first L-shaped plate 24 and the first connecting plate 23 can be connected perpendicularly, and the long plate of the second L-shaped plate 26 and the second connecting plate 25 can be connected perpendicularly.

[0309] In this embodiment, both the first L-shaped card plate 24 and the second L-shaped card plate 26 may have a card slot structure, and the card engaging part 1307 may have a structure that engages with the card slot structure, and is not limited to the above structure.

[0310] like Figure 32 As shown, the first connecting member 13a is a single, integral structure; as Figure 33 As shown, the second connecting member 13b is a single, integral structure. In practice, the first connecting member 13a and the second connecting member 13b can also be two separate components, with each first connecting member 13a and each second connecting member 13b having one overlapping portion 1304 and one snap-fit ​​portion 1307.

[0311] In this embodiment, it is also possible to select one overlapping portion 1304 and one snap-fit ​​portion 1307 in each of the first connecting members 13a and each of the second connecting members 13b.

[0312] In this embodiment, the first end frame 1 and the second end frame 2 have the same structure.
