[0041] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0042] To simplify the drawings, only the parts relevant to the utility model are schematically shown in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically shown or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

[0043] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0044] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0045] Reference Figures 1 to 5, which is an embodiment of the present utility model, proposes a solar cell panel, including: a vacuum glass component 2; a photovoltaic component 1; an aluminum frame 3, which is arranged between the vacuum glass component 2 and the photovoltaic component 1, and has a cavity 302 inside the aluminum frame 3. The bottom surface of the vacuum glass component 2, the top surface of the photovoltaic component 1 and the cavity 302 are combined to form a hollow layer 4.

[0046] In the above scheme, by combining vacuum glass with photovoltaic modules, it not only leverages the power generation function of solar cells but also provides excellent thermal insulation performance, while also reducing production costs and facilitating building installation. The vacuum glass consists of two layers of glass with a vacuum layer 204 in between. This layer has an extremely low heat transfer coefficient, significantly reducing building energy consumption. The photovoltaic module 1 includes silicon-based cells (such as single-crystal silicon or thin-film silicon cells), copper indium gallium tin cells, or cadmium telluride cells. An aluminum frame 3 secures the vacuum glass module 2 and photovoltaic module 1. The aluminum frame 3 has an internal cavity 302, which, combined with the bottom surface of the vacuum glass module 2 and the top surface of the photovoltaic module 1, forms a hollow layer 4, enhancing the thermal insulation performance of the overall structure.

[0047] Furthermore, an adhesive layer is provided between the photovoltaic module and the aluminum frame 3. The adhesive layer is provided between the photovoltaic module and the aluminum frame 3 to firmly connect the photovoltaic module and the aluminum frame 3 and to seal the photovoltaic module to prevent moisture and air from entering the hollow layer 4.

[0048] Furthermore, there are several connecting rods 9, which are rotatably arranged on the mounting plate 8. The connecting rods 9 have a first locking portion 12 and a second locking portion 11. After the connecting rods 9 are rotated, the first locking portion 12 is clamped on the vacuum glass assembly 2, and the second locking portion 11 is clamped on the photovoltaic assembly.

[0049] In the above scheme, a connecting rod 9 is provided on the mounting plate 8 and has a first locking portion 12 and a second locking portion 11. By rotating the connecting rod 9, the vacuum glass assembly 2 and the photovoltaic assembly can be firmly fixed, while ensuring the stability and safety of the structure. During installation, the solar panel of this embodiment is connected to the vacuum glass assembly 2 and the photovoltaic assembly respectively via the first locking portion 12 and the second locking portion 11 of the connecting rod 9, forming a stable structure. The hollow layer 4 within the aluminum frame 3, combined with the thermal insulation properties of the vacuum glass, greatly reduces heat loss from the building. At the same time, the photovoltaic assembly 1 can absorb sunlight and convert it into electrical energy, achieving the dual benefits of building energy conservation and power generation.

[0050] Furthermore, the vacuum glass assembly 2 includes: a first frame 201; a vacuum glass layer 1 202, which is arranged in the first frame 201; a vacuum glass layer 2 203, which is arranged in the second frame 104, the vacuum glass layer 1 202 and the vacuum glass layer 2 203 are arranged in parallel, and a vacuum layer 204 is formed between the vacuum glass layer 1 202 and the vacuum glass layer 2 203; the bottom surface of the vacuum glass layer 2 203 is arranged on the upper surface of the aluminum frame 3; and a plurality of supports 205, which are arranged at intervals in the vacuum layer 204, with one end of the support 205 being arranged on the bottom surface of the vacuum glass layer 1 202 and the other end being arranged on the top surface of the vacuum glass layer 2 203.

[0051] In the above scheme, the first frame 201 and the second frame 104 are used to secure and protect the internal vacuum glass layer. The strength and stability of the frame ensure the structural safety of the entire solar panel. The first vacuum glass layer 202 and the second vacuum glass layer 203 are arranged in parallel, with a vacuum layer 204 formed between the first vacuum glass layer 202 and the second vacuum glass layer 203 to minimize heat conduction and improve thermal insulation performance. The bottom surface of the second vacuum glass layer 203 is set on the upper surface of the aluminum frame 3 and is tightly connected to the photovoltaic module 1. The vacuum layer 204 is vacuumized to form an insulating space with a low heat transfer coefficient, effectively reducing energy loss. The supports 205 are tiny point-shaped or linear structures, evenly distributed within the vacuum layer 204. One end contacts the bottom surface of the first vacuum glass layer 202 and the other end contacts the top surface of the second vacuum glass layer 203. They are used to maintain the distance, strength, or stability between the two layers of glass, prevent the glass layers from contacting due to temperature changes or external forces, and ensure the stability of the vacuum layer 204. When solar energy strikes photovoltaic module 1, it is converted into electrical energy. The double-layer vacuum glass structure effectively isolates the temperature difference between inside and outside, reducing energy loss. The presence of support 205 ensures the long-term stability of vacuum layer 204, maintaining excellent thermal insulation even in extreme weather conditions.

[0052] Furthermore, the photovoltaic module 1 includes: a second frame 104; a first light-transmitting glass plate 101, arranged in the second frame 104; a photoelectric conversion layer 102, arranged on the first light-transmitting glass plate 101; a PVB layer 103, arranged on the photoelectric conversion layer 102; a second light-transmitting glass plate 105, arranged on the PVB layer 103, the second light-transmitting glass plate 105 is located in the second frame 104, the aluminum frame 3 is arranged on the second light-transmitting glass plate 105, and the second light-transmitting glass plate 105, the vacuum glass layer 203 and the cavity 302 are combined to form a hollow layer 4.

[0053] In the above scheme, the second frame 104 is used to fix and protect the internal photovoltaic components to ensure structural integrity and stability. The first light-transmitting glass plate 101 serves as the front-end protection layer of the photovoltaic component and has good light transmittance, ensuring that sufficient light can reach the photoelectric conversion layer 102. The photoelectric conversion layer 102 is composed of solar cells, which are responsible for converting the received solar energy into electrical energy. Silicon-based cells, copper indium gallium selenide cells or cadmium telluride cells can be used. The PVB layer 103 is used to bond the photoelectric conversion layer 102 to the second light-transmitting glass plate 105, while providing additional protection and insulation functions. The second light-transmitting glass plate 105 serves as the rear-end protection layer of the photovoltaic component and also has high light transmittance, but its main function is to protect the photoelectric conversion layer 102 and the PVB layer 103, and also participates in the formation of the hollow layer 4. Integration with the vacuum glass assembly 2: The aluminum frame 3 is set on the second light-transmitting glass plate 105 and together with the second light-transmitting glass plate 105, the second vacuum glass layer 203, and the formed cavity 302, forms a hollow layer 4, further improving the thermal insulation effect. The hollow layer 4 is composed of the second light-transmitting glass plate 105, the second vacuum glass layer 203, and the cavity 302 within the aluminum frame 3. This improves the overall thermal insulation performance of the solar cell panel, enhances the structural stability, and adapts to various climatic conditions. When sunlight passes through the first light-transmitting glass plate 101 and the second light-transmitting glass plate 105, it reaches the photovoltaic conversion layer 102 and is converted into electrical energy. The combination of the double-layer light-transmitting structure and the vacuum layer 204 ensures that the solar cell panel has excellent thermal insulation performance while generating electricity efficiently, reducing the building's energy consumption.

[0054] Furthermore, the aluminum frame 3 has a limiting slide groove 301. The mounting plate 8 is slidably disposed in the limiting slide groove 301, the mounting plate 8 has a receiving groove 801, and the connecting rod 9 is rotatably disposed in the receiving groove 801; the first frame has a first card slot 7, the second frame has a second card slot, and the first locking portion 12 and the second locking portion 11 are respectively disposed at both ends of the connecting rod 9, the first locking portion slidably disposed in the first card slot 7, and the second locking portion 11 slidably disposed in the second card slot.

[0055] In the above scheme, there is a limiting slide groove 301 on the outer side of the aluminum frame 3 for accommodating the mounting plate 8, so that the mounting plate 8 can slide within a certain range, thereby adapting to the needs of different installation positions. A receiving groove 801 is provided on the mounting plate 8 for fixing the connecting rod 9, while allowing the connecting rod 9 to rotate therein to achieve locking with the vacuum glass assembly 2 and the photovoltaic assembly 1. The connecting rod 9 is a structure that can rotate within the receiving groove 801, and a first locking portion 12 and a second locking portion 11 are provided at both ends, respectively, for cooperating with the card slots on the first frame and the second frame to achieve fixation. The first frame and the second frame correspond to the frames of the vacuum glass assembly 2 and the photovoltaic assembly 1, respectively. The first card slot 7 and the second card slot are used to cooperate with the first locking portion 12 and the second locking portion 11 of the connecting rod 9 to ensure a stable connection between the components. During installation, the mounting plate 8 slides along the limiting sliding groove 301 of the aluminum frame 3 to the designated position, and then the connecting rod 9 is rotated to slide the first locking portion 12 and the second locking portion 11 into the first clamping groove 7 and the second clamping groove, respectively, to achieve a secure connection between the vacuum glass assembly 2 and the photovoltaic assembly 1 and the aluminum frame 3. This not only ensures the stability and safety of the solar panel, but also provides adjustability of the installation position.

[0056] Furthermore, the connecting rod 9 has a strip groove 901, and the first locking part 12 and the second locking part 11 have the same structure; the first locking part 12 includes: a round rod 13, which is slidably arranged in the strip groove 901, and the round rod 13 has a sliding end 1301, and the sliding end 1301 is slidably arranged in the first slot 7; a fixed column 14, which is arranged on the connecting rod 9, and the fixed column 14 is located at the end of the strip groove 901 away from the round rod 13; a tension spring 10, one end of which is arranged on the round rod 13, and the other end is arranged on the fixed column 14.

[0057] In the above scheme, the connecting rod 9 is designed with a strip groove 901 for accommodating the components of the locking part, so that the locking part can slide in the strip groove 901 to achieve docking or separation with the first draw-in slot 7 and the second draw-in slot. The first locking part 12 has the same structure as the second locking part 11, and both include: a round rod 13, the round rod 13 can slide in the strip groove 901, and one end of the round rod 13 is a sliding end 1301, which can slide into the first draw-in slot 7 to achieve a fixed connection with the first frame. A fixed post 14 is provided on the connecting rod 9, located at the end of the strip groove 901 away from the round rod 13, and is used to limit the sliding range of the round rod 13. One end of the tension spring 10 is fixed to the round rod 13, and the other end is fixed to the fixed post 14. The function of the tension spring 10 is to make the sliding end 1301 of the round rod 13 slide into the first draw-in slot 7 when there is no external force, thereby achieving automatic locking. When installing or adjusting the position of the solar panel, the user only needs to manually pull the round rod 13 to overcome the tension of the tension spring 10 and make the sliding end 1301 of the round rod 13 disengage from the first slot 7 or the second slot, and then the position can be easily adjusted or disassembled.

[0058] Furthermore, the first card slot 7 has the same structure as the second card slot; the first card slot 7 has an arc segment 701 and a straight segment 702, the straight segment 702 is arranged at one end of the arc segment 701, and the straight segment 702 is connected to the arc segment 701. After the connecting rod 9 is rotated and locked, the sliding end 1301 is engaged in the straight segment 702.

[0059] In the above scheme, the entrance of the slot of the arcuate segment 701 is designed to be arcuate, making it easier for the sliding end 1301 of the round rod 13 to enter the slot. It also provides a certain degree of guidance before the round rod 13 enters the straight segment 702, ensuring that the round rod 13 can smoothly transition to the straight segment 702. The straight segment 702 is connected to the arcuate segment 701, which is used to ultimately secure the sliding end 1301 of the round rod 13. When the connecting rod 9 is rotated into place and locked, the sliding end 1301 will be clamped into the straight segment 702, achieving a stable connection with the first or second frame. When the connecting rod 9 is rotated to achieve locking, the sliding end 1301 of the round rod 13 first enters the slot along the guidance of the arcuate segment 701. As the connecting rod 9 continues to rotate, the sliding end 1301 gradually transitions into the straight segment 702. Finally, under the action of the tension spring 10, the sliding end 1301 is firmly clamped into the straight segment 702, completing the locking process. It not only simplifies the locking steps and improves the locking efficiency, but also ensures the stability of the connection and avoids loosening due to vibration or other factors during use.

[0060] Furthermore, the mounting plate 8 has a slot 802 and also includes: a clamping block 6, which is arranged in the slot 802; an inserting strip 15, one end of which is arranged on the end surface of the round rod 13 away from the sliding end 1301, and the inserting strip 15 has a groove 1501. After the sliding end 1301 is clamped to the straight segment 702, the inserting strip 15 is inserted into the slot 802, and the clamping block 6 is clamped to the groove 1501.

[0061] In the above solution, a slot 802 is provided on the mounting plate 8 for engaging the block 6 and the insert 15 to enhance the stability and connection strength of the connecting rod 9 after it is locked. The block 6 is fixedly disposed in the slot 802 of the mounting plate 8, forming a mating structure with the insert 15 to increase the firmness of the connection. One end of the insert 15 is fixed to the end face of the round rod 13 away from the sliding end 1301. When the sliding end 1301 of the round rod 13 is engaged with the straight section 702, the insert 15 is inserted into the slot 802 of the mounting plate 8, forming a mechanical lock with the block 6, further strengthening the connection between the connecting rod 9 and the mounting plate 8. This not only enhances the stability and strength of the connection, but also prevents the connector from accidentally loosening under external forces, thereby improving the safety of the overall structure of the solar panel.

[0062] Furthermore, the cavity 302 is filled with an inert gas, such as argon, helium or nitrogen, which has stable chemical properties, is not likely to react with other substances, and has good thermal insulation properties.

[0063] Furthermore, the system further includes: a junction box 5 , which is arranged on the outer wall of the second frame 104 , and the junction box 5 is electrically connected to the photoelectric conversion layer 102 .

[0064] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
