Description

Technical Field

[0001] The present application relates to the field of photovoltaic technology, and in particular to a photovoltaic module and a photovoltaic system. Background Art

[0002] With global climate change and environmental pollution becoming increasingly serious, the green and renewable energy industry has experienced rapid growth over the past decade. Solar energy is a renewable resource, and solar cell technology, which utilizes the photovoltaic effect to generate electricity, has garnered significant attention worldwide. Solar cells are made from materials that generate the photovoltaic effect, such as silicon, gallium arsenide, and indium copper selenide, converting sunlight into electricity. Currently, photovoltaic modules, composed of multiple solar cells, are widely used in various photovoltaic power generation systems and as curtain walls for building energy-saving and environmentally friendly structures.

[0003] In practice, due to the high requirements for water vapor permeability in HJT modules, the photovoltaic industry primarily uses butyl adhesive for edge sealing to improve the module's waterproof performance. Currently, HJT modules are typically edge-sealed with tape with holes on both the long and short sides. However, during the edge-sealing and lamination process, butyl adhesive can squeeze out through the vacuum holes (i.e., the holes in the tape), resulting in contamination of the high-temperature cloth and a lack of butyl adhesive at the holes. Butyl adhesive adhered to the laminating high-temperature cloth is difficult to clean. Not only does the laminating machine's high-temperature cloth need to be cleaned at least once per shift, but butyl adhesive on the cloth can also adhere to the module surface, requiring cleaning of each module. Furthermore, butyl adhesive squeezing out of the tape's holes can easily cause the module's water vapor transmission rate to exceed the specified value, thereby reducing the module's waterproof performance and seriously affecting production line efficiency and module quality.

[0037] In order to make the objectives, technical solutions, and advantages of this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and examples. It should be noted that the embodiments and features in the embodiments of this application can be combined with each other unless there is a conflict. This application will be described in detail below with reference to the accompanying drawings and in conjunction with the examples.

[0038] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application described herein can, for example, be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0039] Hereinafter, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. It should be noted that these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0040] like Figures 1-3 As shown, in a first aspect, an embodiment of the present application may provide a photovoltaic assembly, which may include:

[0041] A first glass plate and a second glass plate are provided, with a spacing region formed therebetween. A lead-out hole is provided on the first glass plate, communicating with the spacing region. A junction box 1 is provided on the first glass plate, communicating with the spacing region via the lead-out hole. The first and second glass plates are sealed around their sides with butyl adhesive and edge-sealing tape 2 to close the spacing region. An adhesive film is provided in the spacing region. The first and second glass plates are arranged parallel to and corresponding to each other, and the edge-sealing tape 2 is a non-porous tape.

[0042] In this embodiment, by using a non-porous edge-sealing tape 2 to seal the four sides of the first glass plate and the second glass plate, the problem of butyl rubber overflow can be eliminated, thereby improving the situation where the butyl rubber overflows and sticks to the high-temperature cloth and is difficult to clean, and improving the work efficiency of cleaning the assembly; in addition, the lead-out hole on the first glass plate is connected to the junction box 1, and the lead-out hole can play a role in exhaust, reducing the gas remaining in the photovoltaic module and improving product quality.

[0043] It should be noted that in the conventional technology, butyl rubber and edge-sealing tape 2 are used to seal the first and second glass plates. The edge-sealing tape 2 is a perforated tape, and the holes on the tape facilitate exhaust. However, during the lamination process, butyl rubber is easily squeezed out of the holes on the tape and then adheres to the high-temperature cloth, making it difficult to clean. In addition, since EVA glue is also needed to seal the upper and lower surfaces and the surrounding areas of the first and second glass plates, the butyl rubber will mix with the EVA glue after being perforated, that is, the butyl rubber and the EVA glue will penetrate each other. The mutual flow of the butyl rubber and the EVA glue will cause the butyl rubber to have a poor sealing effect, resulting in poor waterproof performance of the photovoltaic module. However, the present application uses a non-porous edge-sealing tape 2 to seal the first and second glass plates, solving the problem of poor sealing effect of the butyl rubber caused by the mutual penetration of the butyl rubber and the EVA glue, effectively improving the waterproof performance of the photovoltaic module and ensuring the reliability of the photovoltaic module. In addition, since the edge-sealing tape 2 has no holes, the butyl rubber will not be squeezed out onto the high-temperature cloth, which fundamentally solves the problem of cleaning difficulties caused by butyl rubber overflow and greatly improves the working efficiency of the cleaning component.

[0044] In an optional embodiment, the junction box 1 includes a box body 11; the box body 11 defines a mounting chamber 12 for mounting a soldering pad; a through-hole 13 is formed in the bottom wall of the box body 11, which forms the mounting chamber 12. The through-hole 13 can be connected to the corresponding lead-out hole. In the embodiment of the present application, the through-hole 13 can be rectangular.

[0045] In this embodiment, since the middle hole 13 on the junction box 1 is connected to the lead-out hole on the first glass plate, that is, the junction box 1 is connected to the lead-out hole, the potting glue can be infiltrated through the middle hole 13 to seal the lead-out hole on the first glass plate.

[0046] In an optional embodiment, a flowing glue groove is provided on the bottom wall of the box body 11 forming the installation chamber 12; wherein the junction box 1 and the first glass plate are sealed with potting glue, and the flowing glue groove facilitates the flow of the potting glue.

[0047] In this embodiment, by opening a through flow glue groove on the bottom wall of the installation chamber 12, the flow space of the potting glue can be increased, thereby increasing the infiltration and sealing effect of the potting glue on the lead-out hole on the first glass plate, thereby achieving rapid sealing of the lead-out hole.

[0048] In an optional embodiment, the flow groove includes a first flow sub-groove 14 and a second flow sub-groove 15; the first flow sub-groove 14 is located on one side of the central hole 13, and the second flow sub-groove 15 is located on the other side of the central hole 13; wherein the first flow sub-groove 14 and the second flow sub-groove 15 are both opened toward the central hole 13 to facilitate the flow of the potting compound toward the central hole 13. In the embodiment of the present application, the first flow sub-groove 14 and the second flow sub-groove 15 can both be rectangular in shape.

[0049] In this embodiment, the first flow sub-grooves 14 and the second flow sub-grooves 15 are located on either side of the central hole 13. The first and second flow sub-grooves 14, 15 are relatively large, which improves the flow efficiency of the potting compound. This, in turn, reduces the risk of the bottom glue of the junction box 1 clogging the potting compound's leaks due to pressure and deformation during installation. During potting, the potting compound flows toward the center of the bottom wall of the junction box 1, reducing the problem of insufficient coverage of the bottom wall of the junction box 1 due to slow potting compound flow. Furthermore, the potting compound converges toward the lead-out hole of the first glass plate, further improving the sealing efficiency of the lead-out hole and ensuring full coverage of the lead-out hole.

[0050] In an optional embodiment, a first giveway groove 16 is provided on the bottom wall, and the first giveway groove 16 is connected to the first flow sub-groove 14; the first giveway groove 16 is located between the first flow sub-groove 14 and the middle hole 13; a second giveway groove 17 is also provided on the bottom wall, and the first giveway groove 16 is connected to the second flow sub-groove 15; the second giveway groove 17 is located between the second flow sub-groove 15 and the middle hole 13; wherein, along the direction of the first flow sub-groove 14 toward the middle hole 13, the width of the first giveway groove 16 is greater than the width of the first flow sub-groove 14; along the direction of the second flow sub-groove 15 toward the middle hole 13, the width of the second giveway groove 17 is greater than the width of the second flow sub-groove 15.

[0051] In this embodiment, the width of the first give way groove 16 is greater than the width of the first flow sub-groove 14, and the width of the second give way groove 17 is greater than the width of the second flow sub-groove 15. When pouring glue, the potting glue can diffuse through the first give way groove 16 and the second give way groove 17 in the process of flowing to the middle position of the bottom wall, so that the potting glue can adaptively flow to the desired position, reducing the problem of poor flow or accumulation of the potting glue, and increasing the coverage area of ​​the potting glue, improving the sealing effect of the potting glue, and ensuring that the potting glue completely covers the position of the lead-out hole.

[0052] In addition, the provision of the first and second clearance grooves 16 and 17 can act as a buffer, allowing the potting compound to have a certain flow space during the curing process, thereby reducing deformation caused by volume shrinkage during the curing process and maintaining the overall stability and durability of the photovoltaic module.

[0053] In an optional embodiment, the first flow sub-groove 14 and the middle hole 13 are formed in directions perpendicular to each other. In this embodiment, the direction of formation is set to be the length direction of the first flow sub-groove 14 and the middle hole 13 .

[0054] In this embodiment, the potting glue enters the middle hole 13 through the drainage effect of the first flow sub-groove 14 and the second flow sub-groove 15. Since the opening directions of the first flow sub-groove 14 and the middle hole 13 are perpendicular to each other, the potting glue can be evenly distributed around the middle hole 13, and then flows through the middle hole 13 to the lead-out hole position of the first glass plate, which can ensure that the middle hole 13 and all surrounding areas are fully covered by the potting glue, avoiding the occurrence of leaking seals, thereby improving the overall sealing performance.

[0055] In an optional embodiment, a support column 18 is further provided on the bottom wall, and one end of the support column 18 away from the bottom wall is used to connect to the welding pad; wherein a reserved space is formed between the welding pad and the bottom wall to facilitate the flow of the potting glue.

[0056] In this embodiment, the number of support columns 18 is eight, four in a group, a total of two groups, and the two groups of support columns 18 are respectively located on both sides of the middle hole 13; the support columns 18 support the welding disk so that the potting glue can flow through the reserved space, reducing the influence of the welding disk on the flow of the potting glue, so as to ensure the coverage of the middle hole by the potting glue.

[0057] In an optional embodiment, there are multiple support columns 18 , and the multiple support columns 18 are arranged parallel to each other.

[0058] In this embodiment, a plurality of support columns 18 are arranged parallel to each other, which can improve the support stability of the welding plate.

[0059] In an optional embodiment, the potting glue is a high-resistance water-resistant potting glue.

[0060] In this embodiment, the high water-resistance potting glue may be a butyl potting glue, or a silicone potting glue with lower water permeability, so as to further improve the sealing effect of the photovoltaic module.

The photovoltaic arrays are connected to a combiner box, which can combine the current generated by the photovoltaic arrays. The combined current flows through an inverter and is converted into the alternating current required by the mains power grid before being connected to the mains power grid to achieve solar power supply.
