Description

Technical Field

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

[0002] With the development of the photovoltaic industry, the competition for photovoltaic module power is becoming increasingly fierce. Photovoltaic module power refers to the ability of photovoltaic modules to generate direct current, usually measured in watts (W). It is one of the important indicators for evaluating the performance of photovoltaic modules. The higher the power, the stronger the photovoltaic module's power generation capacity under the same area.

[0003] Photovoltaic modules are installed on photovoltaic brackets so that the light-entering surface of the photovoltaic modules can receive as much light as possible and generate more electricity. With the development of the photovoltaic industry, the installation scenarios of photovoltaic power stations have become diverse. Currently, there are several photovoltaic modules that are horizontal or have a small angle with the horizontal plane on the market. For example: for low-angle installation scenarios such as industrial and commercial roofs and floating power stations on the water, as well as low-latitude scenarios, the installation angle of photovoltaic modules is small with the horizontal plane. In addition, since the side wall of the frame located on the light-entering side of the laminate is usually provided with a glue storage tank, the frame structure protrudes a large distance from the light-entering surface of the laminate.

[0004] When the photovoltaic module is installed horizontally or at a small angle, the protruding frame structure will prevent rainwater from being completely drained, and the mirror formed by the rainwater will reflect part of the sunlight shining on the laminate; at the same time, the rainwater will absorb dust in the air, and after the rainwater evaporates, the dust will adhere to the front glass surface of the photovoltaic module. The accumulated water and dust will block the surface of the photovoltaic module, which will not only affect the power generation of the photovoltaic module, but also easily cause local hot spots on the photovoltaic module, reduce the service life of the photovoltaic module, and even cause damage to the photovoltaic module in severe cases.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0029] With the development of the photovoltaic industry, the competition for the power of photovoltaic modules is becoming increasingly fierce. At present, there are several photovoltaic modules that are horizontal or have a small angle with the horizontal plane on the market. Since the side wall of the frame 100 located on the side of the light-entering surface 103 of the laminate is usually provided with a glue storage tank 106, the frame 100 structure protrudes a large distance from the light-entering surface 103 of the laminate. When the photovoltaic module is installed horizontally or at a small installation angle, the protruding structure of the frame 100 will cause the rainwater to not be completely discharged, and the mirror surface formed by the rainwater will reflect part of the sunlight shining on the laminate; at the same time, the rainwater will absorb dust in the air. After the rainwater evaporates, the dust will adhere to the glass surface on the front of the photovoltaic module, blocking the module, thereby seriously affecting the power generation of the module.

[0030] Reference Figure 1 and Figure 2 As shown, an embodiment of the present application provides a photovoltaic laminate frame, including a frame 100; the frame 100 is arranged along the periphery of the photovoltaic laminate 101; the frame 100 has a slot 102, and the edge of the photovoltaic laminate 101 is embedded in the slot 102; the slot 102 has a first clamping side wall 104 that abuts against a side of a light incident surface 103 of the photovoltaic laminate 101; the first clamping side wall 104 is provided with a drainage groove 105, and the opening direction of the drainage groove 105 is away from the light incident surface 103 of the photovoltaic laminate 101.

[0031] It should be noted that many manufacturers now make grooves on the frame 100, which will completely cut off the aluminum alloy frame 100 on the laminate. Although this can eliminate the barrier of the frame 100 to the accumulated water, it will bring two disadvantages. First, the load capacity of the module frame 100 is greatly reduced. Second, the groove will expose the edge of the module laminate, and water will invade the inside of the module from the edge of the laminate, greatly reducing the waterproof performance of the module and reducing the service life of the photovoltaic module. Secondly, the top view of the groove solutions currently on the market is mostly rectangular, which is not conducive to the discharge of accumulated water.

[0032] Reference Figure 2 and Figure 3 As shown, in the embodiment of the present application, a preset angle X is formed between the bottom surface 107 of the drainage groove 105 and the light incident surface 103 of the photovoltaic laminate 101 , and the bottom surface 107 of the drainage groove 105 is higher than the light incident surface 103 of the photovoltaic laminate 101 .

[0033] That is to say, the depth of the drainage groove 105 provided on the frame 100 in the embodiment of the present application is limited, and the depth of the drainage groove 105 is not extended below the light incident surface 103. Therefore, the portion where the drainage groove 105 is provided can retain a strong structural support capability. In addition, the bottom surface 107 of the drainage groove 105 is higher than the light incident surface 103 of the photovoltaic laminate 101, which can prevent the side of the photovoltaic laminate 101 from being exposed, prevent the reduction of the waterproof performance of the photovoltaic module, and ensure that the service life of the photovoltaic laminate 101 is not affected.

[0034] It should be noted that the bottom surface 107 of the drainage groove 105 is 0.5-1.5 mm higher than the light-entering surface 103 of the photovoltaic laminate 101 in contact with the first clamping side wall 104. While ensuring the structural strength, it is also beneficial to the discharge of water. If the thickness is less than 0.5 mm, the strength of the frame 100 where the drainage groove 105 is provided cannot be guaranteed, and the full load requirement cannot be met. If the thickness is greater than 1.5 mm, it is not conducive to the discharge of water. Therefore, those skilled in the art can make a selection according to their needs. For example, the bottom surface 107 of the drainage groove 105 is 1.2-1.3 mm higher than the light-entering surface 103 of the photovoltaic laminate 101 in contact with the first clamping side wall 104.

[0035] In addition, the bottom surface 107 of the drainage groove 105 of the embodiment of the present application and the light incident surface 103 of the photovoltaic laminate 101 are preset at an angle X, and the specific value of the preset angle X can be specifically set by a person skilled in the art as needed. It should be noted that the bottom surface 107 of the drainage groove 105 and the light incident surface 103 of the photovoltaic laminate 101 can also be arranged in parallel.

[0036] The preset angle X between the bottom surface 107 of the drainage groove 105 and the horizontal plane can be 5°-10°, which is consistent with the inclination angle of the light incident surface 103 of the photovoltaic laminate 101. The preset angle X is limited by the installation conditions of the photovoltaic laminate 101, and the angle of 5°-10° is convenient for matching installation with the photovoltaic laminate 101. The preset angle X of 5°-10° can avoid water accumulation between the photovoltaic laminate 101 and the frame 100, which is convenient for the drainage of rainwater, and at the same time, the dust on the surface of the photovoltaic module is removed by the flushing force of the drainage.

[0037] Reference Figure 4 As shown, as an optional embodiment, the bottom surface 107 of the groove of the drainage groove 105 is tightly fitted with the light incident surface 103 of the photovoltaic laminate 101, and a waterproof protective plate 111 is provided at one end of the drainage groove 105 to fit the side wall of the frame 100, and side protective plates 112 for sealing the glue storage tank 106 are provided on both sides of the extension direction of the drainage groove 105.

[0038] The embodiment of the present application also provides a photovoltaic laminate frame, including a frame 100; the frame 100 is arranged along the periphery of the photovoltaic laminate 101; the frame 100 has a slot 102, and the edge of the photovoltaic laminate 101 is embedded in the slot 102; the slot 102 has a first clamping side wall 104 that abuts against the side of the light incident surface 103 of the photovoltaic laminate 101; the first clamping side wall 104 is provided with a drainage groove 105, and the opening direction of the drainage groove 105 is away from the light incident surface 103 of the photovoltaic laminate 101.

[0039] The embodiment of the present application can timely drain rainwater on the light incident surface 103 of the photovoltaic laminate 101 through the provision of the drainage groove 105, avoid the accumulation of rainwater and dust, thereby preventing rainwater and dust from blocking the solar cells, and improving the power generation capacity of the photovoltaic module.

[0040] In addition, the drainage groove 105 of the embodiment of the present application will not reduce the structural strength of the photovoltaic laminate frame, so that the installation frame 100 still has a relatively high strength.

[0041] Reference Figure 2 As shown, as an optional embodiment, a glue storage groove 106 is provided on the side of the first clamping side wall 104 that contacts the photovoltaic laminate 101; the extension direction of the glue storage groove 106 is consistent with the extension direction of the frame 100, and the opening of the glue storage groove 106 faces the light incident surface 103 of the photovoltaic laminate 101.

[0042] Furthermore, in the embodiment of the present application, a glue storage groove 106 is provided on the first clamping side wall 104 , and the provision of the glue storage groove 106 can effectively enhance the bonding strength.

[0043] As an optional implementation, the drainage groove 105 extends in a direction perpendicular to the glue storage groove 106 and passes through the glue storage groove 106 .

[0044] The length of the drainage groove 105 is 15-35 mm. To ensure that the water flow rate can be accelerated at the drainage groove 105, the length of the drainage groove 105 is set between 15 mm and 35 mm. Exemplarily, the length of the drainage groove 105 is 25 mm.

[0045] It should be noted that the embodiment of the present application forms a drainage groove 105 by partially slotting the first clamping side wall 104 of the frame 100. The design of partially opening the drainage groove 105 not only retains the internal structure of the glue storage tank 106, but also greatly reduces the height of the frame 100 to block water. Since the drainage groove 105 is narrow and lower than other positions, the flow rate of water can be accelerated at the narrow notch, and the flow rate brings a certain potential energy to discharge dust out of the component, achieving a certain self-cleaning effect; if the drainage groove 105 is too wide, the water flow rate is slow, and the flushing effect at the drainage groove 105 is limited, which may cause dust accumulation and affect the light reception of the photovoltaic component; for example, the length of the drainage groove 105 is 100mm, which will reduce the strength of the frame 100 on the one hand, and cause the water flow rate to be slow on the other hand, reducing the flushing force on the dust, making it difficult to achieve a good automatic cleaning function of the light-entering surface 103.

[0046] In addition, the drainage groove 105 on the frame 100 does not completely remove the first clamping side wall 104, and a partial structure is left. Compared with the opening groove on the installation frame 100, the advantage is that the installation frame 100 has a strong structural load capacity, and the edge of the photovoltaic laminate 101 is still wrapped by the frame 100, and the photovoltaic laminate 101 is not exposed, so the waterproof performance of the photovoltaic laminate 101 is maintained.

[0047] As an optional implementation, the photovoltaic laminate 101 is rectangular, and the frame 100 forms a rectangular frame 100 ; a plurality of drainage grooves 105 distributed at intervals are arranged on the rectangular frame 100 .

[0048] Among them, the plane where the rectangular frame 100 is located has a preset angle X with the horizontal plane; the frame 100 set horizontally and close to the horizontal plane is provided with at least one drainage groove 105, and the inclined frame 100 is provided with at least one drainage groove 105 at one end close to the horizontal plane.

[0049] It should be noted that the specific position and number of the drainage grooves 105 on the rectangular frame 100 can be set by those skilled in the art as required, and there is no special limitation on this.

[0050] Reference Figure 2 As shown, as an optional embodiment, the slot 102 has a second clamping side wall 108 and a middle connecting side wall 109; the second clamping side wall 108 contacts the backlight side of the photovoltaic laminate 101, and one side of the middle connecting side wall 109 connects the first clamping side wall 104 and the second clamping side wall 108.

[0051] Reference Figure 1 As shown, as an optional embodiment, both ends of the drainage groove 105 have concave rounded corners 110.

[0052] The drain groove 105 of the embodiment of the present application has concave fillets 110 at both ends. The curved surface connection of the concave fillets 110 makes the appearance more beautiful, and the curved surface makes the water flow less resisted at the two ends of the drain groove 105, which is more conducive to the drainage of water.

[0053] It should be noted that the radius of the concave fillet 110 can be set by those skilled in the art as required, and no special limitation is imposed on this.

[0054] Exemplarily, the radius of the concave fillet 110 is 13 mm.

[0055] The present application provides a photovoltaic assembly, including a photovoltaic laminate 101, the above-mentioned photovoltaic laminate frame and a fixing bracket; the photovoltaic laminate frame is arranged around the periphery of the photovoltaic laminate 101; the frame of the photovoltaic laminate frame is fixed to the fixing bracket by bolt connectors.

[0056] In summary, the photovoltaic assembly provided in the embodiment of the present application can timely discharge rainwater on the light incident surface 103 of the photovoltaic laminate 101 through the provision of the drainage groove 105, and at the same time, the rainwater washes away the accumulated dust, thereby avoiding the accumulation of rainwater and dust and improving the power generation capacity of the photovoltaic assembly.

[0057] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
