Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic solar power generation, and in particular to a photovoltaic tile assembly for photovoltaic building integration, a manufacturing method thereof, and a lead method thereof. Background Art

[0002] Photovoltaic tile assemblies are an innovative product that combines solar cells with architectural tiles. They are primarily used on building roofs, replacing traditional tiles and achieving both photovoltaic power generation and building material functions. Their structure typically includes a multi-layer structure consisting of a front panel (such as tempered glass), an encapsulating film, cells (such as monocrystalline silicon cells), and a back panel. The front panel, typically tempered glass, offers excellent light transmittance and mechanical strength, protecting the cells from the external environment while allowing sunlight to pass through for photoelectric conversion. The encapsulating film bonds the cells to the front and back panels, providing a seal and protective barrier against moisture, dust, and other intrusions that could affect their performance and lifespan. The cells are the core component of the photovoltaic tile assembly, converting light energy into electricity through the photovoltaic effect. The back panel not only provides protection but may also provide a heat dissipation function to improve the efficiency of the cells.

[0003] The operating principle of photovoltaic tile modules is based on the photovoltaic effect of semiconductors. When sunlight strikes the surface of a solar cell, the photon energy is absorbed by the cell, causing electrons within the cell to transition from the valence band to the conduction band, forming electron-hole pairs. Under the influence of the cell's PN junction electric field, the electrons and holes are separated and directed to migrate, generating a potential difference across the cell, creating a current. This generated electrical energy can be output and utilized by connecting it to an external circuit.

[0004] Currently, photovoltaic tile assemblies still face some problems and shortcomings in practical applications. The first is insufficient waterproofing. For example, one patent mentions creating a recess in the back panel of the tile to accommodate the laminate and applying a waterproof layer to the surface of the recess. However, this design can lead to water seepage in actual construction due to poor sealing or poor quality of the waterproof layer.

[0005] Secondly, there's the issue of installation complexity. The structural design of some PV tile modules is suboptimal, resulting in a cumbersome, difficult, and time-consuming installation process, increasing both cost and construction risk. For example, some PV tile modules require special mounting brackets or connectors, and installation requires high precision. Even the slightest deviation can lead to loose connections between modules, compromising overall performance and aesthetics.

[0006] Furthermore, the issue of high costs is a prominent one. The production of photovoltaic tile modules involves a variety of materials and complex processes, such as intricate frame designs and non-standard photovoltaic glass sizes, all of which increase module production costs. Furthermore, to meet the aesthetic and functional requirements of buildings, the design and manufacture of photovoltaic tile modules must take into account multiple factors, further increasing R&D and production costs.

[0007] Finally, the Volt-Watt modules need to be matched with conventional tiles to achieve modular matching. Due to the existing technical limitations of the photovoltaic industry, the arrangement of module cells is also subject to certain restrictions due to the modular design. In addition, the modularity is usually greater than 2, which also makes it impossible to fully lay the modules during installation.

[0008] These problems and shortcomings arise primarily because the structural design of photovoltaic tile modules requires balancing multiple factors, such as waterproofing, ease of installation, cost control, and power generation efficiency. Improving one performance characteristic can compromise others, making it difficult to achieve optimal overall performance. Therefore, developing more advanced and rational photovoltaic tile module structures and manufacturing processes is crucial for promoting their widespread application. Summary of the Invention

[0010] To achieve the above object, the technical solution of the present invention is as follows:

[0012] In the above scheme, a plurality of battery cells connected in series constitute a battery string, a positive lead is provided on one side of the battery string, a negative lead is provided on the other side of the battery string, and built-in leads of the external diode are provided on both sides of the positive and negative poles of the battery cell; there are two positive and negative connectors, one is connected to the positive lead and the positive pole of the built-in lead of the diode, and the other is connected to the negative lead and the negative pole of the built-in lead of the diode.

[0013] In the above solution, a hooking side groove is provided on one edge of the base tile, an inner hooking groove is provided on the other edge of the base tile, and a fixing hole is provided on the top of the base tile. As a preferred solution, the hooking side groove is a strip-shaped protrusion structure, and the inner hooking groove is a strip-shaped groove structure, and the inner hooking groove and the hooking side groove match each other.

[0014] In the above scheme, when installed on the tile, when the length dimension of the base tile is greater than or equal to the length dimension of the photovoltaic module, the positive and negative connectors are installed in the groove of the base tile and encapsulated by sealant; when the length dimension of the base tile is smaller than the length dimension of the photovoltaic module, the positive and negative connectors are installed on the back of the extended photovoltaic module and located on the top of the base tile.

[0015] A method for manufacturing a photovoltaic tile assembly comprises the following steps:

[0016] S01. Laying a backside adhesive film layer on the backboard of the photovoltaic module;

[0017] S02, laying the battery strings in series in the back film layer;

[0018] S03. After welding according to the circuit design, the front film layer and the front plate of the photovoltaic module are laid separately, and the whole layer is stacked and then a lamination process is performed;

[0019] S04. Cut according to the design size and solder the positive and negative connectors to the positive and negative lead wires on the laminate respectively;

[0020] S05. Composite the laminate with the positive and negative connectors on the base tile, wherein the tile is provided with a groove at the lead position, arrange a sealant in the groove, and seal the lead welding position;

[0021] S06. Curing the sealant to obtain a finished product.

[0022] During implementation, the plate body of the base tile is any one of clay tiles, cement tiles, plastic tiles, and metal tiles; the plate body of the photovoltaic module is any one of transparent CPC front panel, KPK front panel, transparent PC, ETFE, and PVDF; the back material of the photovoltaic module is any one of coated back panel, PC board, resin board, and fiberglass board; the packaging material of the photovoltaic module is any one of EVA, EPE, POE, PVB, and inorganic silica gel; the sealant layer is any one of sealing silica gel, silicone sealant, butyl sealant, structural adhesive, and epoxy sealant; the battery cells in the battery string are any one of full back contact batteries, double-sided electrode batteries, and thin film batteries.

[0023] A method for wiring a photovoltaic tile assembly comprises the following steps:

[0024] S11. Install the first photovoltaic tile on the roof with the tile hanging strips arranged, and drive fixing nails into the tile screw holes; during implementation, the tile hanging strips can be any one of wooden tile hanging strips, metal tile hanging strips, and cement tile hanging strips.

[0025] S12. When placing the second photovoltaic tile on the tile bar, first connect the positive connector of the first tile to the negative connector of the second photovoltaic tile, or first connect the negative connector of the first tile to the positive connector of the second photovoltaic tile;

[0026] S13, placing the second photovoltaic tile on the tile hanging bar, overlapping it with the first photovoltaic tile, and then driving fixing nails into the fixing holes;

[0027] S14. Continue the installation according to the above steps. After a certain number of photovoltaic tiles are installed, an external diode needs to be connected between the photovoltaic tiles. This external diode has a positive and negative connector and a photovoltaic-specific bypass diode sealed inside. The positive and negative connectors have the same specifications as the other positive and negative connectors on the photovoltaic tile.

[0028] S15. After completing the installation of the first row of photovoltaic tiles, proceed to the installation of the second row of photovoltaic tiles. The positive and negative connectors of the photovoltaic tile components in this row are opposite to those in the first row.

[0029] S16. Repeat the above steps to complete the installation of photovoltaic tiles on the roof.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. The base tiles are connected to the photovoltaic module via a sealant layer to form a single photovoltaic tile. Adjacent tiles are connected in series via positive and negative connectors. This sealant layer covers the entire area where the base tiles meet the photovoltaic module, providing a more secure seal and preventing the leaks that can occur at the edges of existing framed photovoltaic tile modules. Furthermore, the hooking of base tiles within the same layer and the overlapping of upper and lower layers provide a waterproofing effect, further enhancing the waterproofing effect after the photovoltaic module is installed.

[0032] 2. In this embodiment, the photovoltaic tile laminate simply needs to be affixed to ordinary tiles, eliminating the need for additional frames or bases, significantly reducing costs. Each tile has built-in positive and negative connectors, eliminating the need for additional diodes and housings on the tile, further reducing costs. The photovoltaic tiles of this invention can be installed without changing the existing tile installation method, reducing engineering training and labor costs.

[0033] 3. By designing the manufacturing method and lead method of the photovoltaic tile assembly, the existing tiles can be fully utilized without the need for separate module matching. The relevant dimensions are designed according to the existing tiles, which is convenient for mass production. Since the base tiles and the photovoltaic modules are in a one-to-one correspondence, they can be fully covered on the roof of the building, thereby improving the power generation efficiency.

DETAILED DESCRIPTION

[0046] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention will now be further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the relevant components of the present invention.

[0047] According to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art may propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are merely illustrative of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0048] The technical solution of the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0049] Example 1, as Figure 1 and Figure 2 As shown, a photovoltaic tile assembly comprises a base tile 1 and a photovoltaic module 2. The base tile 1 is a common tile currently used on building roofs. The base tile 1 is connected to the photovoltaic module 2 via a sealant layer 4 to form a single photovoltaic tile. Two adjacent photovoltaic tiles are connected in series via a positive and negative connector 3. The sealant layer 4 covers the entire portion where the base tile 1 and the photovoltaic module 2 are connected, providing a more secure seal and preventing water leakage caused by insufficient sealing at the edges of the framed photovoltaic tile assembly in the prior art.

[0050] During implementation, the photovoltaic module 2 is bonded with a diode built-in lead 24 and a plurality of battery cells 21 connected in series through a sealant layer 4. The outside of the photovoltaic module 2 is provided with a diode and a positive and negative connector 3 connected to the diode built-in lead and the positive and negative leads of the battery cell 21. The overall bonding of the sealant layer 4 greatly improves the sealing of the two, and the strength is high and the service life is long.

[0051] Therefore, in this embodiment, the photovoltaic tile laminate 2 only needs to be affixed to ordinary tiles, eliminating the need for additional frames or bases, significantly reducing costs. Each photovoltaic tile has built-in positive and negative connectors 3, eliminating the need for additional diodes and boxes on the tile, further reducing costs. The photovoltaic tiles of this invention can be installed without changing the existing tile installation method, reducing training and labor costs during the construction phase.

[0052] Conventional photovoltaic tiles require custom-made raw materials according to design dimensions, or they must be cut from regular-sized raw materials, resulting in significant losses. The photovoltaic tiles of this invention can be produced using regular-sized raw materials in a fully arranged manner, maximizing material utilization and significantly improving raw material utilization.

[0053] See also Figure 3A battery string is composed of multiple battery cells 21 connected in series. A positive lead 21 is provided on one side of the battery string, and a negative lead 23 is provided on the other side. Internal diode leads 24 for externally connected diodes are provided on both the positive and negative sides of the battery cells 21. Two positive and negative connectors 3 are provided: one connects to the positive electrode of the positive lead 21 and the internal diode lead 24, and the other connects to the negative electrode of the negative lead 23 and the internal diode lead 24. Thus, the positive and negative connectors 3 are used to connect the diodes to the battery string. Internal adhesive fixation improves sealing and significantly reduces manufacturing costs.

[0054] Please continue reading Figure 1 A hooking side groove 11 is provided on one side edge of the base tile 1, and a hooking inner groove 12 is provided on the other side edge of the base tile 1. The setting of the hooking side groove 11 and the hooking inner groove 12 is used to hook two adjacent tiles. A fixing hole 14 is provided on the top of the base tile 1, and the fixing hole 14 is used to fix photovoltaic tiles in different rows. As a preferred solution, the hooking side groove 11 is a strip-shaped protrusion type structure, and the hooking inner groove 12 is a strip-shaped groove type structure. The hooking inner groove 12 matches the hooking side groove 11 with each other, and the laid tiles form a whole through mutual hooking and gripping, which has the function of overall wind resistance and pulling resistance.

[0055] Example 2, based on the solution of Example 1, see Figure 6 and Figure 7 When installed on a tile, when the length of base tile 1 is greater than or equal to the length of photovoltaic module 2, positive and negative connectors 3 are installed in grooves 13 of base tile 1 and sealed with sealant, with base tile 1 covering positive and negative connectors 3. In this embodiment, grooves are cut in base tile 1. After a dedicated photovoltaic junction box is installed on the back of the photovoltaic tile laminate 2, it is bonded to base tile 1 to form a photovoltaic tile assembly.

[0056] Example 3, based on the solution of Example 1, see Figure 8 and Figure 9 When the length of the base tile 1 is smaller than that of the photovoltaic module 2, the positive and negative connectors 3 are installed on the back of the extended photovoltaic module 2 and located on top of the base tile 1, with the photovoltaic module 2 covering the positive and negative connectors 3. This embodiment, by lengthening the photovoltaic module 2, arranges the lead position outside the base tile 1, avoiding the need for tile grooves, and has a lower production cost.

[0057] Example 4, please refer to Figure 10 A method for manufacturing a photovoltaic tile assembly comprises the following steps:

[0058] S01, laying a back adhesive film layer 25 on the backboard of the photovoltaic module 2;

[0059] S02, laying the battery strings connected in series in the back film layer 25;

[0060] S03. After welding according to the circuit design, the front adhesive film layer 26 and the front plate of the photovoltaic module 2 are laid separately, and the whole layer is laminated and then a lamination process is performed to make it more compact;

[0061] S04. Cut according to the design size, and weld the positive and negative connectors 3 to the positive and negative lead wires on the photovoltaic module 2 respectively;

[0062] S05. Composite the photovoltaic module 2 with the positive and negative connectors 3 on the base tile 1. The tile is provided with grooves at the lead positions. Sealant is placed in the grooves to seal the lead welding positions.

[0063] S06. Curing the sealant to obtain a finished product.

[0064] During implementation, the plate body of the base tile 1 is any one of clay tiles, cement tiles, plastic tiles, and metal tiles; the plate body of the photovoltaic module 2 is any one of transparent CPC front panel, KPK front panel, transparent PC, ETFE, and PVDF; the back material of the photovoltaic module 2 is any one of coated back panel, PC board, resin board, and fiberglass board; the packaging material of the photovoltaic module 2 is any one of EVA, EPE, POE, PVB, and inorganic silica gel; the sealant layer 4 is any one of sealing silica gel, silicone sealant, butyl sealant, structural adhesive, and epoxy sealant; the battery cells in the battery string are any one of full back contact batteries, double-sided electrode batteries, and thin film batteries.

[0065] The laminates used in the present invention are all made of lightweight and flexible materials. During the production process, large-sized raw materials can be used to fully utilize the production line capacity to produce multiple photovoltaic tile laminates 2 at one time. After cutting, the required photovoltaic tile laminates 2 are obtained, which greatly improves the production capacity.

[0066] Example 5, a lead method for photovoltaic tile assembly, please refer to Figure 1 、 Figure 4 、 Figure 5 , including the following steps:

[0067] S11. Install the first photovoltaic tile on the roof with the tile hanging strips arranged, and drive fixing nails into the tile screw holes; during implementation, the tile hanging strips can be any one of wooden tile hanging strips, metal tile hanging strips, and cement tile hanging strips.

[0068] S12. When placing the second photovoltaic tile on the tile bar, first connect the positive connector 43 of the first tile to the negative connector 45 of the second photovoltaic tile, or first connect the negative connector 45 of the first tile to the positive connector 43 of the second photovoltaic tile;

[0069] S13, placing the second photovoltaic tile on the tile hanging bar, overlapping it with the first photovoltaic tile, and then driving fixing nails into the fixing holes 14;

[0070] S14. Continue installation according to the above steps. After a certain number of photovoltaic tiles are installed, an external diode needs to be connected between the photovoltaic tiles. The external diode has a positive and negative connector 3, and a photovoltaic-specific bypass diode 44 is sealed inside. The positive and negative connector 3 has the same specifications as the other positive and negative connector 3 on the photovoltaic tile.

[0071] S15. After completing the installation of the first row of photovoltaic tiles, proceed to the installation of the second row of photovoltaic tiles. The positive and negative connectors 3 of the photovoltaic tile assemblies in this row are opposite to those in the first row.

[0072] S16. Repeat the above steps to complete the installation of photovoltaic tiles on the roof.

[0073] like Figure 4 As shown, during implementation, connections are made for each row of photovoltaic tiles. First, the positive connector 43 connects to the cell string 41 in the photovoltaic module 2, which contains multiple first-stage cells 41. Then, it connects to the negative connector 45 in another photovoltaic tile via a bypass diode 44, and so on. In the adjacent row of photovoltaic tiles, the negative connector 45 connects to the cell string 41 in the photovoltaic module 2, which contains multiple second-stage cells 42. Then, it connects to the positive connector 43 in another photovoltaic tile via a bypass diode 44. Therefore, when connecting the upper and lower rows of photovoltaic tiles, the positive and negative connectors 3 should be connected in reverse, facilitating the series connection of each row of photovoltaic tiles.

[0074] By designing the manufacturing method and lead method of the photovoltaic tile assembly, the existing tiles can be fully utilized without the need for separate module matching. The relevant dimensions are designed according to the existing tiles, which is convenient for mass production. Since the base tiles 1 and the photovoltaic modules 2 are in a one-to-one correspondence, they can be fully covered on the roof of the building, thereby improving the power generation efficiency.
