Description

Technical Field

[0001] This utility model relates to the field of building energy conservation and carbon reduction technology, and in particular to a connection structure, a photovoltaic skylight mounting bracket, and a photovoltaic skylight system. Background Technology

[0002] Public buildings have significantly higher energy consumption and carbon emission intensity per unit area than other types of buildings. Therefore, research on energy-saving and carbon-reduction technologies for large public buildings is of significant theoretical and practical value for achieving the dual goals of improving energy efficiency and controlling carbon emissions in the building sector. While the usable space on the roofs of large public buildings is limited, the effective utilization of photovoltaics can be achieved by optimizing the photovoltaic integration design of the atrium skylights. Based on the concept of building-integrated photovoltaics (BIPV), applying cadmium telluride photovoltaic modules to the atrium skylights of large commercial buildings can not only meet the building's natural lighting needs but also achieve synergistic optimization of photovoltaic power generation and building functions. This technological approach can not only reduce the building's dependence on traditional fossil fuels during operation but also significantly improve the building's environmental performance, which is of great significance for reducing building carbon emissions.

[0003] In large commercial buildings, atrium design can significantly improve the efficiency of natural lighting and ventilation, thereby optimizing indoor environmental comfort and reducing building energy consumption. By combining cadmium telluride photovoltaic skylights with traditional windows, it is possible to achieve efficient layout and application of photovoltaic modules while meeting architectural aesthetic requirements.

[0004] However, in practical engineering applications, due to the difference in the overall system thickness between cadmium telluride photovoltaic skylights and traditional skylights under the same thermal performance requirements, it is difficult to connect them when they are integrated and installed on the roof or skylight structure. It is also difficult to achieve a flat and uniform exterior side, which in turn affects the overall air tightness, water tightness and aesthetics of the building skylight location.

[0029] The following is combined with Figures 1-5 Describe the connection structure of this utility model.

[0030] An embodiment of the first aspect of this utility model provides a connection structure for connecting a photovoltaic skylight 100 and a skylight 200, such as... Figures 1 to 3 As shown, the connection structure includes a mounting bracket 310, a support component 320 disposed on the mounting bracket 310, and an adjustment component 330 disposed on the support component 320.

[0031] The support component 320 has a first connecting part and a second connecting part on the side opposite to the mounting bracket 310. The first connecting part has a first structural adhesive layer 340, which is used to fix the photovoltaic skylight 100. The adjustment component 330 includes an adjustment part 331 and a positioning part 332. The adjustment part 331 is connected to the second connecting part, and the positioning part 332 is connected to the adjustment part 331. The adjustment part 331 is used to adjust the height difference between the positioning part 332 and the first connecting part. The positioning part 332 has a second structural adhesive layer 333, which is used to fix the skylight 200.

[0032] Understandably, the support component 320 is mounted on the mounting bracket 310. The support component 320 has a first connecting portion and a second connecting portion spaced apart on the side opposite to the mounting bracket 310. The first connecting portion has a first structural adhesive layer 340 for fixing the photovoltaic skylight 100. The second connecting portion is connected to an adjusting component 331, on which a positioning component 332 is mounted. The positioning component 332 has a second structural adhesive layer 333 for fixing the skylight 200, thereby achieving reliable integrated installation of the photovoltaic skylight 100 and the skylight 200, improving installation convenience. Simultaneously, the height of the positioning component 332 can be adjusted by adjusting the adjusting component 331, thereby adjusting the height difference between the positioning component 332 and the first connecting portion, achieving control over the installation position of the skylight 200, ensuring a flat outer surface after the photovoltaic skylight 100 and the skylight 200 are connected, effectively guaranteeing the overall airtightness, watertightness, and external aesthetics of the building's skylight location.

[0033] The connection structure provided in this embodiment of the utility model improves the convenience of integrated installation of the photovoltaic skylight 100 and the light window 200 by setting a first connecting part and a second connecting part on the support component 320 and using the first structural adhesive layer 340 and the second structural adhesive layer 333 respectively. At the same time, the height difference between the positioning part 332 and the first connecting part is adjusted by using the adjustment component 330 to adjust the installation position of the light window 200, ensuring the flatness of the outer surface of the photovoltaic skylight 100 and the light window 200 after installation, thereby effectively ensuring the overall air tightness, water tightness and external aesthetics of the building skylight position.

[0034] It should be noted that the connection structure in this embodiment integrates the skylight and photovoltaic skylight 100, effectively meeting the building's natural lighting requirements, optimizing the indoor lighting environment, and improving spatial comfort. Simultaneously, it fully utilizes the photoelectric conversion efficiency of the corresponding photovoltaic modules within the skylight, achieving on-site collection and utilization of clean energy. Thus, by organically combining lighting functionality with photovoltaic power generation, it significantly improves overall energy efficiency while ensuring building performance, providing a feasible technical path for the promotion and application of building-integrated photovoltaics (BIPV) technology, and demonstrating good energy-saving benefits and promising engineering application prospects.

[0035] In one embodiment of this utility model, such as Figure 2 As shown, the first connecting part is connected to the second connecting member 360, and the second connecting member 360 has a limiting part for limiting the end face of the photovoltaic skylight 100, so as to realize the positioning and effective constraint of the installation position of the photovoltaic skylight 100.

[0036] For example, the second connector 360 adopts an L-shaped structure. One side of the second connector 360 is connected to the side of the first connector that is away from the first structural adhesive layer 340, while the other side extends to the outside of the end face of the photovoltaic skylight 100, forming a lateral limiting and blocking effect on the end of the photovoltaic skylight 100.

[0037] Understandably, the photovoltaic skylight 100 is positioned by the coordinated action of the second connector 360 and the first connector. Specifically, the first connector provides a preliminary installation reference, and the limiting portion on the second connector 360 further ensures the stability of the photovoltaic skylight 100 in its position, preventing unnecessary movement during use. Furthermore, a first structural adhesive layer 340 is provided on the first connector to firmly fix the photovoltaic skylight 100 to the first connector. Further, a first structural adhesive layer is also provided on the limiting portion, which not only physically limits the end of the photovoltaic skylight 100 but also achieves a tight bond between the limiting portion and the end of the photovoltaic skylight 100 through the adhesive layer, enhancing the reliability of the photovoltaic skylight 100's fixation.

[0038] In one embodiment of this utility model, the adjusting component 331 is used to adjust the height of the positioning component 332. The adjusting component 331 can be a screw adjusting mechanism. The screw adjusting mechanism includes an adjusting screw with threads and a matching nut. The second connecting part is provided with a threaded hole for installing one end of the adjusting screw. The other end of the adjusting screw passes through the through hole on the positioning component 332 and is locked by the nut.

[0039] In actual operation, by rotating the adjusting screw, the positioning component 332 can be moved up and down along the axial direction of the screw, thereby adjusting the height difference between the positioning component 332 and the first connecting part. After reaching the desired height position, the positioning component 332 is firmly locked onto the adjusting screw using a nut to ensure its stability. Once the position of the positioning component 332 is determined, the light-transmitting window 200 can be securely bonded to the positioning component 332 using the second structural adhesive layer 333.

[0040] In one embodiment of this utility model, such as Figure 2 As shown, the connection structure also includes sealant 370, which is disposed on the side of the limiting part away from the photovoltaic skylight 100. The sealant 370 is used to connect with the end face of the skylight 200.

[0041] Understandably, the photovoltaic skylight 100 and the light-transmitting window 200 are installed at corresponding positions on the connecting structure, and a certain preset distance, such as 20mm, is reserved between the end faces of the photovoltaic skylight 100 and the light-transmitting window 200 for the arrangement of the photovoltaic junction box 110 and the photovoltaic cable 120 that cooperate with the photovoltaic skylight 100; and sealant 370 is set between the end faces of the photovoltaic skylight 100 and the light-transmitting window 200 to achieve sealing.

[0042] In this embodiment, the sealant 370 includes expanding foam and foam strips; the expanding foam includes, but is not limited to, polyurethane expanding foam. The gap between the end faces of the photovoltaic skylight 100 and the light-transmitting window 200 is sealed with expanding foam, and then filled with foam strips.

[0043] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the positioning element 332 is provided with an elastic element 380, which allows the skylight 200 to make flexible contact with the positioning element 332 during installation, avoiding wear or damage to the surface of the skylight 200 caused by rigid contact. The elastic element 380 can provide appropriate cushioning and adjustment during installation, ensuring that the skylight 200 can be positioned without damage. After the skylight 200 is initially positioned by the elastic element 380, structural adhesive is filled into the gap between the positioning element 332 and the skylight 200 to form a second structural adhesive layer 333 for fixing the skylight 200.

[0044] In this embodiment, the second structural adhesive layer 333 is made of silicone structural adhesive.

[0045] It should be noted that elastic elements can also be provided on the first connecting part to achieve flexible positioning of the photovoltaic skylight; the first structural adhesive layer 340 is made of silicone structural adhesive.

[0046] In one embodiment of this utility model, such as Figure 2 As shown, the support assembly 320 includes a first support frame 321, a second support frame 322, and a connecting component 390; the first end (i.e., the bottom end) of the first support frame 321 is disposed on the mounting bracket 310, and the second end (top end) of the first support frame 321 is provided with a first connecting portion; the first end (bottom end) of the second support frame 322 is disposed on the mounting bracket 310, and the first support frame 321 and the second support frame 322 are arranged at intervals, and the second end (top end) of the second support frame 322 is provided with a second connecting portion; the connecting component 390 is used to connect and fix the first support frame 321 and the second support frame 322 to the mounting bracket 310.

[0047] It is understood that the support assembly 320 adopts a split structure, specifically including a first support frame 321, a second support frame 322, and a connecting component 390. The first support frame 321 and the second support frame 322 are arranged laterally on the mounting bracket 310. The end of the first support frame 321 away from the mounting bracket 310 serves as the first connecting part, and the end of the second support frame 322 away from the mounting bracket 310 serves as the second connecting part. The first support frame 321 and the second support frame 322 are connected to the mounting bracket 310 through the connecting component 390.

[0048] It should be noted that the support component 320 in this embodiment adopts a split structure design, which can effectively avoid the demolding difficulties that exist in the processing of traditional one-piece components. Specifically, one-piece support components are usually complex in structure and have deep cavities. Especially when multiple connecting parts and installation structures are set, the mold design is difficult, and the demolding process is prone to jamming or damage to components, resulting in reduced yield and increased production costs. In contrast, the support component 320 in this embodiment adopts a split design, and each support frame (first support frame 321 and second support frame 322) can be processed and formed independently, simplifying the structure and making mold manufacturing and demolding more convenient, which is conducive to improving processing accuracy and production efficiency. At the same time, the first support frame 321, the second support frame 322 and the mounting bracket 310 are assembled and connected on site through the connecting component 390, which not only enhances the convenience of component transportation, but also significantly improves the assembly flexibility and operation efficiency on the construction site.

[0049] In one embodiment of the present invention, the two ends of the connecting component 390 are respectively disposed on the first support frame 321 and the second support frame 322, and the connecting component 390 is connected to the mounting bracket 310.

[0050] Optionally, the two ends of the connecting component 390 are respectively attached to the first support frame 321 and the second support frame 322, and the middle part of the connecting component 390 is connected to the mounting bracket 310.

[0051] like Figure 2 and Figure 3 As shown, the connecting component 390 includes a pressure block 391 and a first connecting member 392. A first overlapping member 3211 is provided on the side of the first support frame 321 near the second support frame 322, and a second overlapping member 3221 is provided on the side of the second support frame 322 near the first support frame 321. The two ends of the pressure block 391 overlap the first overlapping member 3211 and the second overlapping member 3221, respectively. A third connecting part 311 extending upward is provided on the mounting bracket 310. The third connecting part 311 is located between the first support frame 321 and the second support frame, and is located below the middle part of the pressure block 391. The first connecting member 392 connects the middle part of the pressure block 391 and the third connecting part 311, thereby realizing the connection between the first support frame 321, the second support frame 322 and the mounting bracket 310.

[0052] It should be noted that the connecting component 390 firmly connects the first support frame 321, the second support frame 322 and the mounting bracket 310 to enhance the overall stability, thereby ensuring that the support component 320 has sufficient strength and rigidity when supporting the photovoltaic skylight 100 and the light-transmitting window 200, and improving the stability and reliability of the entire connection structure.

[0053] In this embodiment, the first support frame 321, the second support frame 322, and the pressure block 391 are all made of aluminum alloy profiles.

[0054] In this embodiment, the first connector 392 is a bolt, and the third connector 311 is a connecting column set on the mounting bracket 310. The connecting column is provided with a first threaded hole that mates with the bolt, and the pressure block 391 is provided with a second threaded hole that mates with the bolt. The first support frame 321, the second support frame 322 and the mounting bracket 310 are connected by bolts to the first threaded hole and the second threaded hole.

[0055] Furthermore, the end of the first lap joint 3211 is provided with a first positioning part, and the end of the pressure block 391 is provided with a second positioning part that cooperates with the first positioning part.

[0056] Understandably, the first lap joint 3211 has a first positioning part at its end, and the corresponding end of the pressure block 391 has a second positioning part that mates with it. When the pressure block 391 laps onto the first lap joint 3211, the first positioning part and the second positioning part engage or align with each other to form a positioning connection structure. This positioning fit effectively limits the relative displacement between the pressure block 391 and the first lap joint 3211, ensuring that the pressure block 391 is accurately positioned and does not shift during installation, thus improving assembly accuracy and connection stability.

[0057] It should be noted that the ends of the second lap joint 3221 and the corresponding ends of the pressure block 391 can also be provided with the aforementioned matching first positioning part and second positioning part; of course, the ends of the first lap joint 3211 and the second lap joint 3221 can also be provided with the first positioning part, and the two ends of the pressure block 391 can be provided with the second positioning part, thereby enhancing the structural consistency and overall rigidity of the entire support assembly 320, reducing installation errors, and improving construction efficiency and connection reliability.

[0058] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the mounting bracket 310 is provided with a first mounting groove 312, and a portion of the support component 320 is disposed in the first mounting groove 312; a sealing element 350 is provided between the edge of the side wall of the first mounting groove 312 and the support component 320.

[0059] It is understood that the mounting bracket 310 is provided with a first mounting groove 312, and at least a part of the structure of the support component 320 is embedded and accommodated in the first mounting groove 312, thereby achieving stable positioning and structural integration between the support component 320 and the mounting bracket 310, which helps to improve the overall connection strength and assembly accuracy.

[0060] A seal 350 is provided between the edge of the side wall of the first mounting groove 312 and the support assembly 320. The seal 350 can effectively block external moisture from seeping in from the gap and prevent water leakage, thereby enhancing the connection and sealing between the support assembly 320 and the mounting bracket 310.

[0061] In this embodiment, the sealing element 350 is a sealing strip to achieve sealing and buffering of force between the mounting bracket 310 and the support assembly 320.

[0062] Optionally, the inner wall of the first mounting groove 312 is provided with a waterproof component 314, such as a waterproof coating or a waterproof pad, to form multiple waterproof barriers.

[0063] Understandably, the synergistic effect of the seal 350 and the waterproof component 314 significantly improves the weather resistance and waterproof reliability of the connection structure in outdoor or humid environments, effectively avoiding structural corrosion or internal leakage problems caused by water seepage, and effectively ensuring the long-term stable operation of the photovoltaic skylight system.

[0064] In this embodiment, a flexible element is provided between the first support frame 321 and the bottom of the first mounting groove 312. The flexible element can buffer and dampen vibrations, effectively absorbing thermal expansion and contraction stress and structural displacement caused by temperature changes, wind loads, or building deformation, avoiding stress concentration that may be caused by rigid connections, reducing the risk of cracking or damage, and thus improving the durability of the connection structure. It should be noted that a flexible element is also provided between the second support frame 322 and the bottom of the first mounting groove 312. For example, the flexible element is a flexible pad block provided at the lower end of the second support frame 322.

[0065] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the mounting bracket 310 is provided with a second mounting groove 313 opposite to the first mounting groove 312.

[0066] It is understood that the mounting bracket 310 is used to fix it to the building or roof structural frame 400, and the second mounting groove 313 formed therein constitutes an independent installation space. The structural frame 400 is provided with a connecting support block 410 extending into the installation space. By embedding the connecting support block 410 into the second mounting groove 313, and using the third connector 500 to fix the connecting support block 410 to the second mounting groove 313, a stable assembly between the mounting bracket 310 and the structural frame 400 is achieved.

[0067] Optionally, the lower part of the mounting bracket 310 is provided with mounting spaces on both sides of the second mounting groove 313, the mounting spaces having openings and openings with openable covers 315.

[0068] Among them, the 315 buckle cover uses a powder-coated aluminum alloy buckle cover.

[0069] Understandably, the lower part of the mounting bracket 310 has mounting spaces on both sides of the second mounting groove 313. These mounting spaces provide ample operating channels for the installation and subsequent disassembly and maintenance of the third connector 500, improving assembly efficiency and maintenance convenience. The mounting space has an outward-facing opening with an openable cover 315. After the fastening of the third connector 500 is completed, the mounting space can be sealed by closing the cover 315, effectively sealing and protecting the internal connection parts, preventing the intrusion of external moisture, dust, and corrosive media, and avoiding rust or aging problems caused by long-term exposure of the third connector 500. This extends the service life of the connection structure and improves the overall reliability and durability of the connection.

[0070] The second aspect of this utility model provides a photovoltaic skylight mounting bracket, which includes a structural frame 400 and a connecting structure 300 provided in any of the above embodiments. The structural frame 400 has an outwardly extending connecting support block 410, and the mounting bracket 310 is connected to the connecting support block 410.

[0071] It is understood that the structural frame 400 is provided with an outwardly extending connecting block 410, and the mounting bracket 310 is fixed to the structural frame 400 by connecting with the connecting block 410, thereby realizing the stable assembly of the connecting structure 300 and the main structure.

[0072] In this embodiment, the structural frame 400 is made of steel; the connecting support block 410 is made of U-shaped channel steel fixed on the structural frame 400; the connecting support block 410 is embedded in the second mounting groove 313 of the mounting bracket 310, and the connecting support block 410 and the second mounting groove 313 are fixedly connected by the third connector 500.

[0073] The third connector 500 uses a connecting bolt made of stainless steel. A washer 600 is provided between the connecting support block 410 and the side wall of the second mounting groove 313. Furthermore, a washer 600 is also provided between the nut of the connecting bolt and the outer side wall of the second mounting groove 313, and a washer 600 is also provided between the nut on the connecting bolt and the outer side wall of the second mounting groove 313.

[0074] Optionally, the connection structure 300 can be arranged in multiple spaced intervals to achieve continuous and integrated connection of multiple photovoltaic skylights 100 and light-transmitting windows 200.

[0075] It should be noted that by setting multiple connecting structures 300, the installation requirements of large-span or modular roofing systems can be accommodated, and flexible combinations of windows of different sizes and shapes can be achieved, improving overall assembly efficiency. At the same time, the unified height adjustment and positioning mechanism between the connecting structures 300 ensures that the surface of the multiple windows is flat and the joints are uniform after connection, effectively improving the overall integrity and aesthetics of the building's appearance.

[0076] A third aspect of this utility model provides a photovoltaic skylight system, which includes a photovoltaic skylight 100, a light-transmitting window 200, and a photovoltaic skylight mounting bracket provided in any of the above embodiments.

[0077] In this system, the photovoltaic skylight 100 and the light-transmitting window 200 are mounted on the connecting structure 300 of the photovoltaic skylight mounting frame. They are reliably fixed to the support component 320 and the adjustment component 330 via a first structural adhesive layer 340 and a second structural adhesive layer 333, respectively. The photovoltaic skylight mounting frame provides structural support and positioning for the photovoltaic skylight 100, and also allows for flexible adjustment of the installation height of the light-transmitting window 200 via an adjustable positioning component 332, ensuring that both surfaces are flush and the transition is natural after installation. Thus, this embodiment integrates photovoltaic power generation, natural lighting, and building envelope functions into one system, offering advantages such as convenient installation, stable connection, and aesthetically pleasing appearance, while also possessing excellent waterproof, sealing, and durability performance.

[0078] In this embodiment, adjacent photovoltaic skylights 100 and daylighting windows 200 form a single window unit. Each window unit is installed and positioned via a corresponding connecting structure 300. The mounting bracket 310 of the connecting structure 300 is fixed to connecting blocks 410 on the structural frame 400. The number and position of the connecting blocks 410 match the window units one by one. Thus, the window units, connecting structures 300, and connecting blocks 410 correspond in number and arrangement, forming a modular integrated installation system. This not only improves assembly efficiency and structural stability but also ensures the coordination of connections between units and the neatness and uniformity of appearance, thereby ensuring the integrity of the building envelope. This system is suitable for large-scale, array-based building photovoltaic integrated systems.

[0079] like Figure 4 and Figure 5As shown, the photovoltaic skylight system includes multiple photovoltaic skylights 100 and multiple daylighting windows 200, arranged in an array to form a regular and orderly interface for building lighting and power generation. Each column in the array consists of windows of the same type; for example, the first column consists of multiple photovoltaic skylights 100 arranged sequentially, and the second column consists of multiple daylighting windows 200 arranged sequentially. Adjacent columns are structurally connected and integrated through a connecting structure 300. Specifically, each photovoltaic skylight 100 in the first column is horizontally connected to its corresponding daylighting window 200 in the second column through a connecting structure 300, ensuring precise alignment in height and planar position, and a flat and uniform appearance. Correspondingly, the mounting bracket 310 of the connecting structure 300 is fixed to the connecting support block 410 on the structural frame 400, thereby effectively transferring the load of the photovoltaic skylights 100 and daylighting windows 200 to the structural frame 400.

[0080] In one embodiment of this utility model, the photovoltaic skylight system includes photovoltaic modules, a light-transmitting window, a structural frame, and the connection structure provided in any of the above embodiments.

[0081] The photovoltaic module includes a photovoltaic skylight 100, a photovoltaic junction box 110, and a photovoltaic cable 120. The photovoltaic skylight adopts TP5+1.52PVB+3.2CdTe thin-film photovoltaic glass+1.52PVB+TP5 single silver Low-E+12A+HS6+1.52PVB+HS6 ultra-clear tempered hollow Low-E glass. Among them, TP5 represents 5mm thick transparent float glass; PVB represents 1.52mm thick polyvinyl butyral film; 3.2CdTe thin-film photovoltaic glass represents 3.2mm thick cadmium telluride thin-film solar power generation glass; single silver Low-E represents single-layer silver-based low-emissivity coated glass; 12A represents 12mm thick air layer; HS6 represents 6mm thick ultra-clear tempered glass; HS6 ultra-clear tempered hollow Low-E glass refers to a hollow sandwich structure composed of HS6+1.52PVB+HS6, with the outer glass having a Low-E coating.

[0082] The skylight uses TP8+12Ar+HS6+1.52PVB+HS6 double-insulated tempered double-silver Low-E glass; where TP8 represents 8mm thick transparent float glass; 12Ar represents 12mm thick argon-filled layer; HS6 represents two 6mm thick ultra-clear tempered glass panes; 1.52PVB represents 1.52mm thick polyvinyl butyral film; and double-silver Low-E glass represents double-layer silver-based low-emissivity coated glass.

[0083] The assembly process of the photovoltaic skylight system in this embodiment: Mounting bracket 310 is set on structural frame 400. Mounting bracket 310 and connecting support block 410 on structural frame 400 are connected by third connector 500. The third connector 500 is made of stainless steel bolt and has washer 600 on it. The first support frame 321 and the second support frame 322 are disposed on the mounting bracket 310, and the two ends of the pressure block 391 are respectively disposed on the first support frame 321 and the second support frame 322. The first connector 392 is connected to the middle part of the pressure block 391 and the third connector 311 on the mounting bracket 310 to realize the connection and fixation of the first support frame 321, the second support frame 322 and the mounting bracket 310; at the same time, a sealing element 350 is provided at the contact position between the edge of the mounting bracket 310 and the support assembly 320. A first connecting part is provided on the first support frame 321 for the photovoltaic skylight 100. The first connecting part is connected to a second connecting member 360 by screws. The second connecting member 360 has a limiting part for limiting the end face of the photovoltaic skylight 100. Silicone sealant is filled between the photovoltaic skylight 100 and the first connecting part to form a first structural adhesive layer 340 for fixing the photovoltaic skylight 100 on the first connecting part.

[0084] The skylight 200 is mounted on the adjusting component 331 on the second support frame 322. Silicone sealant is filled between the skylight 200 and the positioning component 332 of the adjusting component 331 to form a second structural adhesive layer 333 on the positioning component 332 for fixing the skylight 200. The height of the positioning component 332 is adjusted by the adjusting component 331 to ensure the flatness of the photovoltaic skylight 100 and the skylight 200 on the outdoor side, thereby ensuring the overall airtightness and watertightness of the photovoltaic skylight system.

[0085] There is a certain preset distance between the photovoltaic skylight 100 and the light-transmitting window 200. Sealant 370 is applied to the gap between the end faces of the photovoltaic skylight 100 and the light-transmitting window 200 to achieve a seal.

[0086] After the installation of the photovoltaic skylight 100 and the light-transmitting window 200 is completed, the photovoltaic modules are connected by photovoltaic cables 120 according to the arrangement of the light-transmitting skylight positions. In this embodiment, the photovoltaic modules are connected in series in groups of three, and finally connected to the inverter after being combined by the current combining device, thereby forming a photovoltaic skylight system.
