[0055] With the continuous development of building-integrated photovoltaic (BIPV) technology, the demand for integrating photovoltaic modules directly into building structures is increasing. BIPV can not only achieve energy self-sufficiency, but also improve the aesthetics and functionality of buildings. However, there are many problems with the traditional installation method of BIPV photovoltaic modules, such as difficulty in replacement, poor sealing performance, and insufficient thermal insulation, which limit the widespread promotion of BIPV technology in practical applications.

[0056] Most existing BIPV photovoltaic modules are installed in a fixed manner. Once damaged or needing to be replaced, they must be operated outdoors, which is particularly inconvenient for high-rise buildings. In addition, traditional fixing methods may result in poor sealing, affecting the thermal insulation performance of the building, and even causing water seepage problems. Therefore, there is an urgent need for a photovoltaic module structure and construction method that can be quickly replaced indoors to improve the maintenance efficiency and overall performance of the BIPV system.

[0057] Therefore, there is an urgent need for a photovoltaic module for rapid indoor replacement to solve at least one of the above problems.

[0058] To solve the above problems, please refer to Figure 1 , Figure 1 It is a schematic flow chart of a method for manufacturing a photovoltaic module for indoor rapid replacement provided in one embodiment of the present application.

[0059] Specifically, Figure 1 As shown, the method for manufacturing a photovoltaic module for indoor rapid replacement includes steps S101 to S107. The prepared photovoltaic module is as follows Figure 2-4 As shown, the support unit 2 is as shown in Figure 1 The corresponding steps are described as follows:

[0060] Step S101. In a preset indoor environment, provide a photovoltaic module and obtain size information of the photovoltaic module.

[0061] Specifically, in a preset indoor environment, a photovoltaic module 1 is provided, and various dimensional parameters (such as length, width, thickness, etc.) of the photovoltaic module 1 are accurately measured. Assuming that the size of the photovoltaic module 1 is 1000mm × 1500mm × 5mm, these dimensional data will be used for the subsequent production of the special profile 2. Ensure that the special profile 2 can accurately fit the photovoltaic module 1, thereby improving the installation stability and sealing performance of the module.

[0062] Step S102: According to the size information, a special profile corresponding to the photovoltaic component is manufactured on a preset mold; the special profile includes a groove adapted to the photovoltaic component.

[0063] Specifically, according to the size information obtained in step S101, a special profile 2 corresponding to the photovoltaic module 1 is made on a preset mold, and a groove 13 adapted to the photovoltaic module 1 is provided on the special profile 2. If the mold is used to make an aluminum profile, the size of the groove 13 is 1000mm × 1500mm × 6mm, which is slightly larger than the size of the photovoltaic module 1 to ensure the convenience and sealing of the installation. The customized design of the special profile 2 can better adapt to photovoltaic modules 1 of different specifications and improve the flexibility and sealing of the installation. Step S103. Press a preset silicone strip into the groove 13.

[0064] Specifically, a preset silicone strip 14 is pressed into the groove 13 of the special profile 2 to enhance the sealing performance and shock absorption effect. For example, a silicone strip 14 with a length of 1500 mm, a width of 5 mm, and a height of 3 mm is pressed into the bottom of the groove 13 to ensure that the silicone strip 14 is in full contact with the bottom of the groove 13. The silicone strip 14 has good sealing performance and shock absorption effect, can effectively prevent moisture penetration, and reduce vibration and damage of the photovoltaic module 1 during use.

[0065] Step S104: Structural adhesive is applied in the groove, and the photovoltaic module is bonded to the groove via the structural adhesive; a gap is formed after the photovoltaic module is bonded to the groove.

[0066] Specifically, the structural adhesive 11 is applied in the groove 13, and then the photovoltaic module 1 is bonded to the groove 13 through the structural adhesive 11, and a gap is formed after bonding. For example, a high-performance structural adhesive 11 with a thickness of 2 mm is evenly applied in the groove 13, and the photovoltaic module 1 is embedded in the groove 13 and gently pressed to make it fully contact with the structural adhesive 11. The structural adhesive 11 not only provides a strong bonding force, but also enhances the sealing performance between the module and the profile, and improves the stability and durability of the overall structure.

[0067] Step S105. Paste a preset closed sponge in the gap between the photovoltaic component and the groove to ensure that the photovoltaic component is in full contact with the surface of the closed sponge to isolate the photovoltaic component from the influence of external temperature.

[0068] Specifically, a preset closed sponge 9 is pasted in the gap between the photovoltaic module 1 and the groove 13 to ensure that the photovoltaic module 1 is in full contact with the surface of the closed sponge 9 to isolate the photovoltaic module 1 from the influence of the external temperature. For example, a closed sponge 9 with a length of 1500 mm, a width of 5 mm, and a height of 2 mm is pasted in the gap to ensure that it is in full contact with the surface of the photovoltaic module 1 and the special profile 2. The closed sponge 9 has good thermal insulation performance, can effectively isolate the influence of the external temperature on the photovoltaic module 1, improve the thermal insulation effect of the building, and extend the service life of the photovoltaic module 1.

[0069] Step S106: inserting a foam rod into the outer side of the closed sponge to ensure that there is no gap between the photovoltaic module and the special profile.

[0070] Specifically, a foam rod 15 is inserted outside the closed sponge 9 to ensure that there is no gap between the photovoltaic module 1 and the special profile 2. For example, a foam rod 15 with a diameter of 5 mm is inserted into the gap between the closed sponge 9 and the special profile 2 to ensure that the foam rod 15 fills all the gaps. The filling of the foam rod 15 can further enhance the sealing performance, prevent moisture penetration, reduce heat conduction, and improve the overall thermal insulation effect.

[0071] Step S107: Apply weather-resistant sealant on the outer side of the foam rod to obtain a finished photovoltaic module.

[0072] Specifically, the weatherproof sealant 10 is applied on the outer side of the foam rod 15, and finally the finished photovoltaic module is obtained. For example, a 1 mm thick weatherproof sealant 10 is evenly applied on the outer side of the foam rod 15 to ensure that the entire gap is completely sealed. The weatherproof sealant 10 has excellent waterproof and anti-aging properties, can maintain the sealing effect for a long time, prevent moisture penetration, and extend the service life of the photovoltaic module.

[0073] The above steps, through the use of customized special profiles 2 and multi-layer sealing materials (silicone strips 14, closed sponges 9, foam rods 15, weather-resistant sealants 10), not only solve the problems of poor sealing performance and insufficient thermal insulation effect of traditional fixed installation, but also realize the rapid replacement of photovoltaic modules indoors, improving maintenance efficiency and overall performance. This method is particularly suitable for BIPV systems in high-rise buildings, which is both beautiful and practical, and is expected to be more widely used in the future.

[0074] In some embodiments, after obtaining the completed photovoltaic module, it also includes: processing a notched profile compatible with the special profile 2 according to the structural information corresponding to the special profile 2; the notched profile includes a vertical frame 3, a horizontal frame 4 and a lower horizontal frame 5 compatible with the special profile 2; in a preset outdoor environment, the special profile 2 corresponding to the completed photovoltaic module is fixed in the lower horizontal frame 5, and the vertical frame 3, the horizontal frame 4 and the lower horizontal frame 5 cooperate to fix the photovoltaic module in the outdoor environment.

[0075] like Figure 3 and 4 As shown, after obtaining the finished photovoltaic module, a notched profile that matches the special profile 2 is processed according to the structural information corresponding to the special profile 2. The notched profile includes a vertical frame 3, a horizontal frame 4 and a lower horizontal frame 5.

[0076] In a preset outdoor environment, the special profile 2 corresponding to the finished photovoltaic module is fixed in the lower horizontal frame 5. The photovoltaic module is fixed in the outdoor environment through the cooperation of the vertical frame 3, the horizontal frame 4 and the lower horizontal frame 5. Structural information acquisition: According to the size and structural information of the special profile 2, the corresponding notched profile is designed and processed. Vertical frame 3: used to support the vertical direction of the photovoltaic module. Horizontal frame 4: used to support the horizontal direction of the photovoltaic module. Lower horizontal frame 5: used to fix the lower part of the special profile 2 to ensure that the photovoltaic module is stable and does not shift during the installation process.

[0077] In outdoor environments, the lower horizontal frame 5 is pre-installed to ensure that it is firmly fixed on the building structure. The manufactured special profile 2 of the photovoltaic module is embedded in the lower horizontal frame 5, and its position is ensured to be accurate. The vertical frame 3 and the horizontal frame 4 are fixed around the special profile 2, and through their cooperation with the lower horizontal frame 5, the fixity and stability of the photovoltaic module in the outdoor environment are ensured.

[0078] Through the pre-processed notched profile and outdoor fixed frame, the photovoltaic module can be quickly and accurately fixed on the exterior wall of the building, greatly improving the installation efficiency and construction speed. The cooperation of the vertical frame 3, the horizontal frame 4 and the lower horizontal frame 5 provides multi-directional fixed support to ensure the stability and safety of the photovoltaic module under adverse weather conditions such as wind and rain. The combined design of the special profile 2 and the notched profile allows the photovoltaic module to be quickly disassembled from the room when maintenance or replacement is required, reducing the risk and complexity of high-altitude operations. The design and installation of the notched profile can further enhance the sealing performance between the photovoltaic module and the building structure, prevent moisture penetration, and improve the waterproof performance of the building. Through the combination of multi-layer sealing materials and fixed frames, the influence of external temperature on the photovoltaic module 1 can be effectively isolated, the thermal insulation effect of the building can be improved, and energy consumption can be reduced.

[0079] Assuming that the size of the special profile 2 is 1000mm × 1500mm × 6mm, the processed notched profile is as follows:

[0080] Vertical frame 3: height 1500mm, width 100mm, thickness 5mm.

[0081] Horizontal frame 4: length 1000mm, width 100mm, thickness 5mm.

[0082] Lower horizontal frame 5: length 1000mm, width 100mm, thickness 10mm.

[0083] In an outdoor environment, the lower horizontal frame 5 is fixed at a predetermined position on the building's exterior wall, and then the special profile 2 is embedded in the lower horizontal frame 5. Next, the vertical frame 3 and the horizontal frame 4 are fixed around the special profile 2 to ensure that the photovoltaic module is firmly supported in all directions. This design not only improves the stability and sealing of the installation, but also facilitates subsequent maintenance and replacement work.

[0084] By processing the notched profiles that match the special profiles 2, and by the cooperation of the vertical frame 3, the horizontal frame 4 and the lower horizontal frame 5, the photovoltaic module is stably fixed in the outdoor environment. This method not only improves the installation efficiency, but also enhances the sealing performance and thermal insulation effect. It is particularly suitable for BIPV systems in high-rise buildings, making maintenance and replacement work more convenient and safer.

[0085] like Figure 4As shown, the special profile 2 includes a first special profile 2.1 and a second special profile 2.2. The first special profile 2.1 and the cross frame 4, the second special profile 2.2 and the lower cross frame 5 cooperate to complete the assembly, thereby achieving stable fixation of the photovoltaic module in an outdoor environment.

[0086] Exemplarily, the photovoltaic module 1 includes a power generation chip, a panel, a back panel and a junction box 6, the power generation chip is pasted between the panel and the back panel, the junction box 6 is bonded to the back panel, and after the weather-resistant sealant 10 is applied to the outer side of the foam rod 15, it also includes: in the photovoltaic module 1, the wires 7 connected to the junction box 6 are bent in a direction relative to the groove 13; after the wires 7 extend through the cross frame 4 of the notched profile and are connected to the external plug connector 8, the wires 7 and the junction box 6 are connected; and the weather-resistant sealant 10 is applied to the portion of the junction box 6 exposed on the outer side of the back panel.

[0087] The power generation chip is responsible for converting light energy into electrical energy. The panel is usually made of glass material, which protects the power generation chip and is light-transmissive. The backplane protects the back of the power generation chip and is usually made of polymer material. The junction box 6 is used to collect and transmit the electrical energy generated by the photovoltaic module 1 and is bonded to the backplane. After completing step S107 (applying weather-resistant sealant 10 on the outside of the foam rod 15), the following steps are also included: bending the wire 7 connected to the junction box 6 in the direction relative to the groove 13, so that the wire 7 can extend through the notch profile of the special profile 2 and connect to the external plug connector 8. After the wire 7 is extended through the cross frame 4 of the notch profile and connected to the external plug connector 8, the wire 7 and the junction box 6 are connected. Apply weather-resistant sealant 10 to the part of the junction box 6 exposed on the outside of the backplane to enhance the sealing and moisture-proof effect.

[0088] In the groove 13 of the special profile 2, the wire 7 connected to the junction box 6 is appropriately bent in the direction opposite to the groove 13 to ensure that the wire 7 can smoothly pass through the cross frame 4 of the notched profile. Assuming that the length of the wire 7 extending from the junction box 6 is 300 mm, 100 mm of it is slightly bent in the direction of the groove 13 of the special profile 2 to form an arc. The bent wire 7 is extended out of the special profile 2 through the cross frame 4 of the notched profile and connected to the external plug connector 8, and then the wire 7 is reconnected to the junction box 6. If the wire 7 extends out of the special profile 2 through the reserved notch on the cross frame 4, it is connected to the preset plug connector 8, and the connection is ensured to be firm and reliable.

[0089] Apply weatherproof sealant 10 to the exposed portion of the junction box 6 on the outside of the back plate to enhance the sealing and moisture-proof effect of the junction box 6. Apply 1-2 mm thick weatherproof sealant 10 evenly to the exposed portion of the junction box 6 and the back plate to ensure that the junction box 6 is completely isolated from the external environment.

[0090] By bending the wire 7 toward the groove 13, the wire 7 can be more conveniently extended out of the special profile 2 through the horizontal frame 4 of the notched profile, thereby improving the flexibility and convenience of installation. After the wire 7 extends out of the special profile 2 through the horizontal frame 4, the wire 7 and the junction box 6 are connected, thereby ensuring the reliability and stability of the connection and reducing the risk of damage to the wire 7 during installation. The exposed part of the junction box 6 is coated with weather-resistant sealant 10, which can effectively prevent the intrusion of water and moisture, protect the electronic components inside the junction box 6, and extend the service life of the photovoltaic module 1. The design of the wire 7 allows it to be quickly disassembled and reconnected from indoors when maintaining or replacing the photovoltaic module 1, thereby reducing the complexity and risk of high-altitude operations. The bending and sealing treatment of the wire 7 makes the structure of the entire photovoltaic module more compact and beautiful, thereby improving the overall appearance of the building.

[0091] Assume that the size of the photovoltaic module 1 is 1000mm × 1500mm × 5mm, the junction box 6 is located at one of the four corners of the back panel, and the wire 7 extends from the junction box 6 by 300mm. The specific steps are as follows: slightly bend the 100mm long wire 7 toward the groove 13 to form an arc. Extend the bent wire 7 through the reserved notch (width 10mm, height 5mm) on the horizontal frame 4 to the special profile 2, and connect it to the external plug connector 8 to ensure a firm and reliable connection. Evenly apply 1-2mm thick weather-resistant sealant 10 to the part of the junction box 6 exposed on the outside of the back panel to ensure that the junction box 6 is completely isolated from the external environment. Through the above steps, not only the installation stability and sealing performance of the photovoltaic module can be ensured, but also the maintenance efficiency and aesthetics of the system can be improved, which is particularly suitable for the BIPV system of high-rise buildings.

[0092] Exemplarily, the vertical frame 3 is fixed based on bolts 12, and the horizontal frame 4 is transversely fixed based on countersunk screws; the notched profile also includes a vertical frame buckle cover 3.1 corresponding to the vertical frame 3, which is used to close after the vertical frame 3 is fixed to hide the bolt 12; the nut of the countersunk screw is coated with a sealant 10 of the same color as the horizontal frame 4.

[0093] The vertical frame 3 is fixed by bolts 12. The horizontal frame 4 is fixed horizontally by countersunk screws. The vertical frame buckle cover 3.1 is used to close after the vertical frame 3 is fixed to hide the bolts 12. The nuts of the countersunk screws are coated with sealant 10 of the same color as the horizontal frame 4. The vertical frame 3 is fixed to the outside of the groove 13 of the special profile 2 by bolts 12 to ensure that the connection between the vertical frame 3 and the special profile 2 is firm and stable. Assume that the vertical frame 3 has a height of 1500mm, a width of 100mm and a thickness of 5mm. Use 4 bolts 12 with a length of 100mm and a diameter of 10mm to fix it to the outside of the groove 13 of the special profile 2 at the four corners of the vertical frame 3. Use countersunk screws to fix the horizontal frame 4 horizontally to the outside of the groove 13 of the special profile 2 to ensure that the connection between the horizontal frame 4 and the special profile 2 is firm and stable. Assume that the length of the horizontal frame 4 is 1000mm, the width is 100mm and the thickness is 5mm. Use 6 countersunk screws with a length of 30 mm and a diameter of 5 mm to fix them to the outside of the groove 13 of the special profile 2 at uniform positions of the horizontal frame 4. After the vertical frame 3 is fixed, install the vertical frame buckle cover 3.1 to hide the bolts 12 and improve the aesthetics. If the vertical frame buckle cover 3.1 is the same color as the vertical frame 3, it is covered on the bolts 12 of the vertical frame 3 to ensure that the buckle cover 3.1 is seamlessly connected to the surface of the vertical frame 3 to form an overall beautiful effect.

[0094] Apply sealant 10 of the same color as the horizontal frame 4 to the nut of the countersunk screw to enhance the aesthetics and sealing performance. Use high-performance weather-resistant sealant 10 and evenly apply it to the nut of the countersunk screw. The color of the sealant 10 is consistent with the horizontal frame 4 to ensure the hiding and sealing effect of the screw part.

[0095] The fixing method of the bolt 12 of the vertical frame 3 can provide a strong fixing force to ensure the stability and safety of the photovoltaic module in the vertical direction. The fixing method of the countersunk screw of the horizontal frame 4 can provide a uniform fixing force to ensure the stability and safety of the photovoltaic module in the horizontal direction. Installing the vertical frame buckle cover 3.1 can hide the bolt 12 of the vertical frame 3, making the entire installation structure more neat and beautiful, and improving the appearance quality of the building. The nut of the countersunk screw is coated with a sealant 10 of the same color as the horizontal frame 4, which not only hides the screw, but also enhances the sealing performance, further improving the overall aesthetics and durability. The design of the vertical frame buckle cover 3.1 can further enhance the sealing performance between the vertical frame 3 and the special profile 2 to prevent moisture penetration. The sealant 10 applied on the nut can fill the tiny gap between the countersunk screw and the horizontal frame 4, improving the overall waterproof and moisture-proof performance. The fixing method of the bolt 12 and the countersunk screw makes the disassembly and installation of the vertical frame 3 and the horizontal frame 4 more convenient, and is convenient for maintenance and replacement when necessary. The installation and removal of the vertical frame buckle cover 3.1 is also relatively simple, and can be quickly opened to inspect and maintain the bolt 12. The vertical frame 3 and the horizontal frame 4 adopt a multi-point fixing method, which makes the fixing structure of the entire photovoltaic module more reasonable and firm, and improves the overall performance of the system. The color of the vertical frame buckle cover 3.1 and the sealant 10 is consistent with the horizontal frame 4, making the entire installation structure more visually unified and coordinated, and improving the grade and aesthetics of the building.

[0096] Assume that the size of the photovoltaic module 1 is 1000mm × 1500mm × 5mm, and the groove 13 of the special profile 2 is 1000mm × 1500mm × 6mm. The specific steps are as follows:

[0097] Use four bolts 12 with a length of 100 mm and a diameter of 10 mm to fix the vertical frame 3 to the outside of the groove 13 of the special profile 2 at the four corners of the vertical frame 3. For example, the positions of the bolts 12 can be: (0, 0), (0, 1500), (1000, 0), (1000, 1500).

[0098] Use 6 countersunk screws with a length of 30 mm and a diameter of 5 mm to fix the cross frame 4 to the outside of the groove 13 of the special profile 2 at uniform positions. For example, the positions of the screws can be: (200, 750), (400, 750), (600, 750), (800,750), (250, 750), (750, 750).

[0099] Use the mullion buckle cover 3.1 of the same color as the mullion 3 to cover the bolts 12 of the mullion 3, and ensure that the buckle cover 3.1 is seamlessly connected to the surface of the mullion 3. For example, the color of the mullion buckle cover 3.1 can be silver or the same color as the exterior wall of the building, so that it is not easily noticed.

[0100] Use high-performance weather-resistant sealant 10, evenly apply it on the nut of the countersunk screw, and the color of the sealant 10 is consistent with the horizontal frame 4. For example, the sealant 10 can be gray or other colors consistent with the color of the horizontal frame 4, so that it can be integrated with the horizontal frame 4.

[0101] Through the above steps, not only the firm fixation and sealing performance of the photovoltaic modules in the outdoor environment are ensured, but also the overall aesthetics of the building is greatly improved, which is especially suitable for high-rise buildings with high requirements for building appearance. This design and installation method not only improves the reliability and service life of the system, but also simplifies the maintenance and replacement process.

[0102] Exemplarily, before fixing the special profile 2 corresponding to the manufactured photovoltaic module in the lower horizontal frame 5 in a preset outdoor environment, it also includes: obtaining the module size corresponding to the photovoltaic module; if the module size is smaller than the preset size, using a suction cup to transport the photovoltaic module to the outdoor environment for fixation; if the module size is greater than or equal to the preset size, using a hanging basket to transport the photovoltaic module to the outdoor environment.

[0103] Get the specific size of the photovoltaic module to determine the transportation method. If the size is smaller than the preset size, use the suction cup to transport the photovoltaic module to an outdoor environment for fixation. If the size is greater than or equal to the preset size, use the hanging basket to transport the photovoltaic module to an outdoor environment for fixation.

[0104] For example, measure the length, width, and thickness of the photovoltaic module and record its specific dimensions. Assume that the dimensions of the photovoltaic module are 1500mm long, 1000mm wide, and 5mm thick. Assume that the preset dimensions are 1600mm long, 1100mm wide, and 10mm thick. If the dimensions of the photovoltaic module are 1500mm × 1000mm × 5mm, which is smaller than the preset dimensions, choose to use a suction cup for transportation. If the dimensions of the photovoltaic module are 1800mm × 1200mm × 10mm, which is greater than or equal to the preset dimensions, choose to use a hanging basket for transportation.

[0105] Regardless of whether the suction cup or hanging basket is used for transportation, the special profile 2 corresponding to the photovoltaic module is finally fixed in the lower horizontal frame 5, and the vertical frame 3, the horizontal frame 4 and the lower horizontal frame 5 cooperate to ensure that the photovoltaic module is stably fixed in the outdoor environment. For example, in an outdoor environment, the special profile 2 is embedded in the lower horizontal frame 5, and the vertical frame 3 and the horizontal frame 4 are fixed with bolts 12 and countersunk screws to firmly fix the photovoltaic module in the special profile 2.

[0106] For smaller photovoltaic modules, the suction cup can provide sufficient suction to ensure the stability and safety of the modules during transportation, avoiding falling and damage. For larger or heavier photovoltaic modules, the hanging basket can provide a more reliable support and transportation method to ensure the safety of the modules during high-altitude transportation.

[0107] The use of suction cups can quickly transport photovoltaic modules from indoors or on the ground to outdoor installation locations, saving time and labor. For large-sized photovoltaic modules, the use of hanging baskets can efficiently and safely complete the transportation task and improve the overall installation efficiency.

[0108] The use of suction cups reduces the need for operators to manually carry modules at height, reducing the risk of working at height. The use of hanging baskets can ensure the smooth transportation of modules, reduce potential accidents caused by manual handling, and improve safety.

[0109] By judging the size of the photovoltaic module and selecting the appropriate transport tool, the installation method is more flexible and can adapt to photovoltaic modules of different sizes and weights. Whether it is a suction cup or a hanging basket, the photovoltaic module is finally fixed in the special profile 2, and the stability and reliability of the system are ensured through multi-point fixing and sealing.

[0110] Assuming the preset dimensions are 1600mm long, 1100mm wide, and 10mm thick, the specific steps are as follows:

[0111] Get module size: Measure the size of the PV module, assuming it is 1500mm × 1000mm × 5mm.

[0112] Module size judgment: The module size is 1500mm × 1000mm × 5mm, which is smaller than the preset size of 1600mm × 1100mm × 10mm.

[0113] Transportation method selection: Choose to use suction cups for transportation. Use 4 suction cups and fix them at the four corners of the photovoltaic module to ensure uniform and sufficient suction. Transport the photovoltaic module from indoors or on the ground to the outdoor installation location to ensure smooth and safe process.

[0114] In an outdoor environment, the special profile 2 is embedded in the lower horizontal frame 5. The vertical frame 3 is fixed to the outside of the groove 13 of the special profile 2 using bolts 12. The horizontal frame 4 is laterally fixed to the outside of the groove 13 of the special profile 2 using countersunk screws. The photovoltaic module is firmly fixed in the special profile 2, and the vertical frame 3, the horizontal frame 4 and the lower horizontal frame 5 cooperate to ensure its stability and safety in an outdoor environment.

[0115] If the size of the PV module is 1800mm × 1200mm × 10mm, the specific steps are as follows:

[0116] Measure the size of the PV module, assuming it is 1800mm × 1200mm × 10mm. The module size is 1800mm × 1200mm × 10mm, which is greater than or equal to the preset size of 1600mm × 1100mm × 10mm. Choose to use a hanging basket for transportation. Place the PV module in the hanging basket, ensuring that the module is stable and will not slide. Use lifting equipment to transport the hanging basket from the ground to the outdoor installation location, ensuring stability and safety during the process. In the outdoor environment, embed the special profile 2 into the lower cross frame 5. Use bolts 12 to fix the vertical frame 3 to the outside of the groove 13 of the special profile 2. Use countersunk screws to fix the horizontal frame 4 horizontally to the outside of the groove 13 of the special profile 2. Fix the PV module firmly in the special profile 2, and ensure its stability and safety in the outdoor environment through the cooperation of the vertical frame 3, the horizontal frame 4 and the lower cross frame 5.

[0117] By selecting the appropriate transport tool (suction cup or hanging basket) according to the size of the photovoltaic module, the safe transportation and stable fixation of the photovoltaic module in the outdoor environment is ensured. This method not only improves the installation efficiency and reduces the risk of high-altitude operations, but also adapts to photovoltaic modules of different sizes and weights, improving the reliability and aesthetics of the overall system. It is particularly suitable for BIPV systems in high-rise buildings, ensuring the efficiency and safety of the installation process.

[0118] In some embodiments, before pasting a preset closed sponge 9 in the gap between the photovoltaic module 1 and the groove 13, it also includes: obtaining the first material information of the silicone strip 14 and the second material information of the structural adhesive 11; judging whether the silicone strip 14 and the structural adhesive 11 are compatible according to the first material information and the second material information; if the silicone strip 14 and the structural adhesive 11 are incompatible, filling the gap between the silicone strip 14 and the structural adhesive 11 according to the double-sided tape.

[0119] The first material information of the silicone strip 14 and the second material information of the structural adhesive 11 are obtained. According to the first material information and the second material information, it is determined whether the silicone strip 14 and the structural adhesive 11 are compatible. If the silicone strip 14 and the structural adhesive 11 are incompatible, a double-sided tape is used to fill the gap between the silicone strip 14 and the structural adhesive 11. A preset closed sponge 9 is pasted in the gap between the photovoltaic module 1 and the groove 13 to further enhance the sealing and moisture-proof effect.

[0120] By consulting the material specification or conducting experiments, the material information of the silicone strip 14 and the structural adhesive 11, including chemical composition, physical properties and compatibility, is obtained. The material information of the silicone strip 14 is: the main component is silicone rubber, which has good weather resistance and elasticity. The material information of the structural adhesive 11 is: the main component is polyurethane glue, which has strong adhesion and water resistance. According to the obtained material information, it is judged whether the silicone strip 14 and the structural adhesive 11 are compatible. The compatibility judgment mainly considers the chemical reaction between the materials, the adhesion and the stability after use. Through the compatibility table or conducting a small sample experiment, it is found that silicone rubber and polyurethane glue may react chemically under long-term contact, resulting in a decrease in adhesion, so it is judged that the two are incompatible. If it is judged that the silicone strip 14 and the structural adhesive 11 are incompatible, a double-sided tape is used to fill the gap between the two to ensure the sealing performance between the photovoltaic module 1 and the special profile 2. For example, a double-sided tape material that is compatible with both the silicone strip 14 and the structural adhesive 11 is selected and pasted in the gap between the silicone strip 14 and the structural adhesive 11 to ensure that the gap is completely sealed.

[0121] A preset closed sponge 9 is pasted in the gap between the photovoltaic module 1 and the groove 13 to further enhance the overall sealing and moisture-proof effect. For example, a closed sponge 9 with a thickness of 3 mm is selected and evenly pasted in the gap between the photovoltaic module 1 and the groove 13 to ensure that the sponge fits tightly with the gap.

[0122] By judging the compatibility of the silicone strip 14 and the structural adhesive 11, the decrease in adhesion and sealing performance caused by material incompatibility is avoided. If the silicone strip 14 is incompatible with the structural adhesive 11, the gap is filled with double-sided tape to further enhance the sealing between the photovoltaic module 1 and the special profile 2 to prevent the intrusion of water and moisture. Ensuring good compatibility between the materials used can improve the long-term stability of the materials and extend the overall service life of the photovoltaic module 1. Pasting the closed sponge 9 not only enhances the sealing, but also buffers the physical impact in the external environment and reduces the risk of damage to the module due to external forces. It ensures the tight fit of each connection part and improves the reliability and stability of the installation. The closed sponge 9 further enhances the sealing performance of the installation and ensures the long-term stable operation of the photovoltaic module 1 in the outdoor environment. Material compatibility judgment avoids the maintenance and replacement costs caused by material incompatibility and reduces unnecessary maintenance work. The double-sided tape and closed sponge 9 improve the overall sealing and stability of the system, reduce the maintenance requirements caused by poor sealing, and save maintenance time and cost.

[0123] Assume that the size of the photovoltaic module 1 is 1000mm × 1500mm × 5mm, and the groove 13 of the special profile 2 is 1000mm × 1500mm × 6mm. The specific steps are as follows:

[0124] Check the material specifications of the silicone strip 14 and the structural adhesive 11 to obtain the following information:

[0125] Silicone strip 14: The main component is silicone rubber, which has good weather resistance and elasticity.

[0126] Structural adhesive 11: The main component is polyurethane adhesive, which has strong adhesion and water resistance.

[0127] After consulting the material compatibility table, it was found that silicone rubber and polyurethane adhesive may react chemically under long-term contact, resulting in a decrease in adhesion. Therefore, it was determined that the two are incompatible.

[0128] Select a double-sided tape material that is compatible with both the silicone strip 14 and the structural adhesive 11, and paste it in the gap between the silicone strip 14 and the structural adhesive 11. For example, use a double-sided tape with a thickness of 1 mm and a width of 10 mm, and paste it evenly in the gap between the silicone strip 14 and the structural adhesive 11. Select a closed sponge 9 with a thickness of 3 mm, and paste it evenly in the gap between the photovoltaic module 1 and the groove 13. For example, evenly paste the closed sponge 9 along the edge of the groove 13 to ensure that it fits tightly in the gap.

[0129] By obtaining the material information of the silicone strip 14 and the structural adhesive 11, judging their compatibility, and using double-sided tape to fill the gap when they are incompatible, good sealing and stability between the photovoltaic module 1 and the special profile 2 are ensured. This method not only improves the sealing performance of the system and prolongs the service life, but also optimizes the installation process and reduces maintenance costs. It is particularly suitable for high-rise building BIPV systems that have high requirements for sealing performance and service life.

[0130] In some embodiments, the step of obtaining the finished photovoltaic module includes: adding a preset glass pressing plate 16 to the outer side of the special profile 2 , and the silicone strip 14 is located between the photovoltaic component 1 and the glass pressing plate 16 .

[0131] like Figure 2-4 As shown, by installing a preset glass pressing plate 16 on the outer side of the special profile 2, it is ensured that the silicone strip 14 is located between the photovoltaic module 1 and the glass pressing plate 16 to provide good sealing and fixing effect. The finished photovoltaic module includes the photovoltaic module 1 and the special profile 2.

[0132] Assume that the outer dimensions of the special profile 2 are 1000mm × 1500mm × 6mm, and the dimensions of the glass platen 16 are 1000mm × 1500mm × 5mm. Use a suitable method (such as bolts 12 or adhesive) to fix the glass platen 16 to the outer side of the special profile 2. For example, a silicone strip 14 with a thickness of 3mm and a width of 10mm is selected and evenly placed in the gap between the photovoltaic module 1 and the glass platen 16, ensuring that the silicone strip 14 completely covers the gap.

[0133] The glass pressing plate 16 can provide an additional protective layer to prevent moisture and dust in the external environment from entering the gap between the photovoltaic module 1 and the special profile 2. The silicone strip 14 is located between the photovoltaic module 1 and the glass pressing plate 16, ensuring a close fit between the two and enhancing the sealing performance. The installation of the glass pressing plate 16 can further enhance the fixing effect of the photovoltaic module 1 in the special profile 2 and improve the stability and safety of the system. The silicone strip 14 has good elasticity and adhesion, which can buffer external impact and reduce the risk of damage to the photovoltaic module 1 due to external forces.

[0134] In some embodiments, the silicone strip 14 is an EPDM strip.

[0135] The EPDM rubber strip has good chemical stability and weather resistance, and is suitable for sealing and fixing the photovoltaic module 1. If the EPDM rubber strip with a thickness of 3 mm and a width of 10 mm is selected, ensure that it meets the installation requirements of the photovoltaic module 1.

[0136] Assume that the size of the photovoltaic module 1 is 1000mm × 1500mm × 5mm, and the groove 13 of the special profile 2 is 1000mm × 1500mm × 6mm. Select an EPDM adhesive strip with a length of 1000mm, a width of 1500mm, and a thickness of 3mm, and place it in the gap between the photovoltaic module 1 and the glass pressing plate 16. Ensure that the EPDM adhesive strip completely covers the gap between the photovoltaic module 1 and the glass pressing plate 16 and is firmly adhered. If a special adhesive is used to adhere the EPDM adhesive strip to the gap between the photovoltaic module 1 and the glass pressing plate 16, ensure that it fits tightly with the gap.

[0137] EPDM rubber strips have excellent weather resistance and can withstand the effects of ultraviolet rays, temperature changes and humidity in outdoor environments for a long time, maintaining good sealing performance. EPDM rubber strips have good resistance to a variety of chemical substances and can reduce the degradation of sealing performance caused by chemical corrosion. EPDM rubber strips have good anti-aging properties and can maintain elasticity and adhesion for a long time, ensuring the long-term stable operation of the photovoltaic module 1 in the outdoor environment. The high elasticity and good compression resilience of EPDM rubber strips can better fill the tiny gap between the photovoltaic module 1 and the glass pressure plate 16, improving the sealing effect. EPDM rubber strips are suitable for a variety of environmental conditions, including high temperature, low temperature, humidity and dryness, etc., to ensure sealing performance under different climatic conditions.

[0138] In some embodiments, pasting a preset closed sponge 9 in the gap between the photovoltaic component 1 and the groove 13 includes: measuring the length and width of the gap based on a preset laser ranging device; determining the length and width of the closed sponge 9 according to the length and width of the gap; wherein the length of the closed sponge 9 is equal to the length of the gap, and the width of the closed sponge 9 is greater than the width of the gap, so as to ensure that there is no gap between the photovoltaic component 1 and the groove 13 after the closed sponge 9 is filled.

[0139] Use a preset laser distance measuring device to measure the length and width of the gap between the photovoltaic module 1 and the groove 13. According to the measured gap size, determine the length and width of the closed sponge 9. The length of the closed sponge 9 should be equal to the length of the gap. The width of the closed sponge 9 should be greater than the width of the gap to ensure that there is no gap between the photovoltaic module 1 and the groove 13 after the closed sponge 9 is filled. Use a laser distance measuring device to accurately measure the gap size between the photovoltaic module 1 and the groove 13. Assume that the measurement results show that the length of the gap is 1000mm and the width is 5mm. According to the measurement results, select or make a suitable closed sponge 9. If a closed sponge 9 with a length of 1000mm and a width of 8mm is selected, ensure that its width is greater than the gap width of 3mm, so as to completely fill the gap. The determined closed sponge 9 is evenly pasted in the gap between the photovoltaic module 1 and the groove 13 to ensure that it fits tightly. If a special adhesive is used to paste the closed sponge 9 in the gap, ensure that it fits tightly with the gap without any gaps.

[0140] The use of laser ranging equipment can accurately measure the length and width of the gap, avoiding errors in manual measurement and ensuring the dimensional accuracy of the closed sponge 9. The width of the closed sponge 9 is greater than the width of the gap, which can ensure that it completely fills the gap and prevents the entry of moisture and dust. The closed sponge 9 has good elasticity and compression resilience, and can provide an excellent sealing effect, further improving the waterproof and dustproof properties of the photovoltaic module 1. Accurate measurement and appropriate size selection can reduce the adjustment time during the installation process and improve installation efficiency. The use of the closed sponge 9 can simplify the installation steps, reduce the need to use other sealing materials, and save time and cost. The closed sponge 9 has good weather resistance and anti-aging properties, can maintain the sealing effect for a long time, and extend the overall service life of the photovoltaic module 1.

[0141] Exemplarily, the length of the foam rod 15 is equal to the length of the groove 13 , and the thickness of the foam rod 15 is less than the thickness of the groove 13 .

[0142] Use a preset laser distance measuring device to measure the length and thickness of the groove 13. Select a foam rod 15 with a length equal to the length of the groove 13 and a thickness less than the thickness of the groove 13. Ensure that the foam rod 15 can be smoothly placed in the groove 13 and provide a good filling effect.

[0143] For example, use a laser distance measuring device to accurately measure the length and thickness of the groove 13. Assume that the measurement results show that the length of the groove 13 is 1500mm and the thickness is 6mm. According to the measurement results, select or make a suitable foam rod 15. For example, select a foam rod 15 with a length of 1500mm and a thickness of 4mm to ensure that it can be smoothly placed in the groove 13 and fill most of the space in the groove 13. Place the selected foam rod 15 into the groove 13 to ensure that it fits tightly with the groove 13. For example, use a special tool to gently press the foam rod 15 into the groove 13 to ensure that it fits tightly with the groove 13 to avoid shaking and uneven filling.

[0144] The foam rod 15 has a good filling effect, is easy to use, can simplify the installation steps, and improve the installation efficiency. The thickness is less than the thickness of the groove 13 to ensure that the foam rod 15 can be smoothly placed in the groove 13, avoiding the problem of being difficult to install due to being too large. The foam rod 15 can provide a preliminary sealing effect, reduce the entry of moisture and dust, and protect the photovoltaic module 1. Before the closed sponge 9 is installed, the foam rod 15 can play a preliminary filling role and improve the overall sealing performance. The foam rod 15 has a certain elasticity and shock absorption effect, which can buffer external impact and protect the photovoltaic module 1 from damage. Placing the foam rod 15 in the groove 13 can reduce the rigid contact between the photovoltaic module 1 and the groove 13 and improve the stability of the system. By selecting foam rods 15 of different thicknesses, it can adapt to grooves 13 of different sizes and improve the flexibility of the system. The use of the foam rod 15 can be applicable to a variety of groove 13 sizes, and there is no need to frequently replace different sealing materials.

[0145] like Figures 2 to 4 As shown, the present application provides a photovoltaic module for quick indoor replacement, comprising: a photovoltaic component 1; a special profile 2 corresponding to the photovoltaic component 1, the special profile 2 comprising a groove 13 adapted to the photovoltaic component 1; a silicone strip 14, pressed into the groove 13; a structural adhesive 11, applied in the groove 13, the photovoltaic component 1 is bonded to the groove 13 through the structural adhesive 11; a gap is formed after the photovoltaic component 1 is bonded to the groove 13; a closed sponge 9 is pasted in the gap between the photovoltaic component 1 and the groove 13, the photovoltaic component 1 is in full contact with the surface of the closed sponge 9 to isolate the photovoltaic component 1 from the influence of external temperature; a foam rod 15, inserted on the outside of the closed sponge 9, for ensuring that there is no gap between the photovoltaic component 1 and the special profile 2; a weather-resistant sealant 10, applied on the outside of the foam rod 15 to complete the sealing of the photovoltaic module.
