Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaics, and in particular relates to a photovoltaic component. Background Art

[0002] Currently, in the photovoltaic field, traditional photovoltaic modules face challenges due to the front frame obstructing the laminate and being higher than the front glass surface. This allows dust, snow, and other debris to accumulate on the module surface. If left uncleaned for extended periods, this can obstruct the solar cells at the module's lower port, impacting power station operation. To address this issue, a photovoltaic module with an unobstructed front frame has been proposed in recent years (e.g., Chinese utility model patent publication number CN216721255U). This type of photovoltaic module achieves an unobstructed front glass surface, solving the problem of water and dust accumulation on the front of the framed module.

[0003] However, the above-mentioned photovoltaic modules with unobstructed front frames still have the following defects:

[0004] 1. Since the frame A side on the upper surface of the glass is removed, the silicone will be exposed. The exposed silicone is prone to weathering and yellowing, and is difficult to clean, affecting the appearance and performance of the component.

[0005] 2. The insulation performance of laminated parts without frame A side protection will be reduced, posing certain safety hazards.

[0006] 3. The load-bearing capacity of components without frame A side protection is reduced, affecting the structural stability and durability of the components.

[0007] In view of this, how to provide a photovoltaic module frame that can achieve self-cleaning of the glass module and ensure the mechanical load performance of the module is an urgent problem that people in this field need to solve. Utility Model Content

[0020] Optionally, the long frame and the short frame are connected by corner brackets.

[0021] Optionally, the upper surface of the frame A is recessed downward to form a glue filling groove.

[0022] Optionally, the front reinforcement tape is a transparent high-strength tape with a width of 5 cm and a thickness of 0.5 mm. The front reinforcement tape has the characteristics of UV resistance and aging resistance, which increases the service life of the component in outdoor environments.

[0031] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0033] Reference Figures 1 to 4 As shown, an embodiment of the present invention provides a photovoltaic module, comprising a laminate 4, a module frame 1, a front reinforcement tape 2, and a back load reinforcement module. The laminate 4 is bonded and supported on the upper surface of the frame A side 11 by silicone rubber 3; the front reinforcement tape 2 bonds the laminate 4 and the module frame 1 together from the upper edge of the laminate 4 and the outside of the frame B side 12. A plurality of back load reinforcement modules are spaced along the length of the module frame 1, each connecting the lower surface of the laminate 4 to the frame C side 13.

[0034] The laminate 4 is mainly composed of back packaging material, a first layer of packaging film, a battery string, a second layer of packaging film, a front packaging material and a junction box, wherein the front packaging material is photovoltaic glass and the back cover material is a photovoltaic backboard or photovoltaic glass.

[0035] In this embodiment, the laminate 4 and the frame are sealed with silica gel 3 , and the upper surface of the edge 11 of the frame A is recessed downward to form a glue-filling groove.

[0036] In this embodiment, the component frame 1 is a frameless A-side 11 component frame 1, including a long frame and a short frame, and the short frame and the long frame are fixedly connected to the corner code, wherein the long frame and the short frame can adopt the same structure or different structures.

[0037] In one possible embodiment, the short frame includes a frame B side 12 and a frame C side 13, and the long frame includes a frame A side 11, a frame B side 12, and a frame C side 13. The frame C side 13 of the long frame is provided with a fixing hole 15 every 50 cm along the length, starting from its center. Each fixing hole 15 has a diameter of 6 mm, and the center point of the fixing hole 15 is 2.5 to 3 cm from the outside of the frame B side 12. The specific distance is set according to the specific specifications of the frame C side 13. The fixing holes 15 are used to pass the bolts 7.

[0038] It should be understood that in this embodiment, the long frame serves as the main support for connecting with the laminate 4, while in some other embodiments, the short frame may also serve as the main support. If the short frame serves as the main support, the short frame includes a frame A side 11, a frame B side 12, and a frame C side 13. Of course, in some possible embodiments, both the long frame and the short frame may serve as supports and include a frame A side 11, a frame B side 12, and a frame C side 13.

[0039] In a possible embodiment, the top of the frame B side 12 of the long frame and / or the short frame is higher than the upper surface of the frame A side 11, and forms an installation position 14 for installing the laminate 4 together with the upper surface of the frame A side 11.

[0040] In a possible embodiment, the front reinforcing tape 2 is a transparent high-strength tape with a width of 5 cm and a thickness of 0.5 mm. The tape is UV-resistant and aging-resistant, and has strong toughness.

[0041] In a possible embodiment, after the silicone rubber 3 of the component is cured for 72 hours, the tape is attached 2 cm inward along the edge of the glass and 3 cm inward to the edge B 12 of the frame, covering the entire assembly.

[0042] In one possible embodiment, the back-load reinforcement module includes transparent high-strength tape, a diamond ribbon 6, a bolt 7, and a nut. The transparent high-strength tape is affixed to the lower surface of the laminate 4, with one tape measuring 100 x 40 mm applied every 50 cm along the back of the laminate 4. Each tape is placed along the long side of the module. One end of the diamond ribbon 6 is bonded to the transparent high-strength tape, and the other end is bonded to the bolt 7. The bolt 7 passes through the bolt 7 fixing hole 15 on the C-side 13 of the frame and is secured with a nut. The nut fixing torque is 5 to 10 Nm.

[0043] Compared with the prior art, the present invention has at least the following advantages:

[0044] 1. A photovoltaic module frame 1 structure is adopted in which the long frame and the short frame do not have the frame A side 11. Dust deposited on the glass module can be naturally washed away by rainwater and flow along the short frame to the outside of the glass module, thereby realizing the function of automatic cleaning.

[0045] 2. Use UV-resistant tape to encapsulate to prevent silica gel from weathering or yellowing.

[0046] 3. Using high-strength angles to define the upper surface of the laminate 4 and the outer side of the frame B edge 12 can effectively increase the mechanical load performance of the component.

[0047] 4. By adding a back load enhancement module to the lower surface of the component, the mechanical load performance of the component can be effectively increased.

[0048] The parts not described in detail in the present invention are conventional technical means well known to those skilled in the art.
