技术领域technical field
本发明涉及一种太阳能光电系统，特别是涉及一种具有缓冲垫的太阳能光电系统。The invention relates to a solar photovoltaic system, in particular to a solar photovoltaic system with a buffer pad.
背景技术Background technique
近年来，绿色居住环境的营造是为各国所提倡的目标，而在高度文明的世界中，由于人类活动的影响，如借由燃烧石油产生动力的各种交通工具中皆会排放二氧化碳，使空气中二氧化碳的含量不断提高，并造成温室效应日趋于严重，以及全球气候暖化现象，因此现今各国不断地积极开发可替代石油的替代能源，而一般替代能源主要可分为生质能源、风力发电或太阳能发电，其中又以太阳能发电最受到瞩目，由于太阳能本身不会产生有公害、能源耗尽的问题且取得容易，因此太阳能相关产业也逐渐蓬勃发展。In recent years, the creation of a green living environment is a goal advocated by various countries. In a highly civilized world, due to the impact of human activities, carbon dioxide will be emitted from various vehicles that generate power by burning oil, making the air The content of carbon dioxide in the environment continues to increase, and the greenhouse effect is becoming more and more serious, as well as the phenomenon of global warming. Therefore, countries are constantly actively developing alternative energy sources that can replace petroleum, and general alternative energy sources can be mainly divided into biomass energy and wind power generation. Or solar power generation, among which solar power generation has attracted the most attention. Since solar energy itself does not cause pollution and energy exhaustion problems and is easy to obtain, solar energy related industries are gradually developing vigorously.
然而，在高纬度地区或常发生强风的地区，太阳能模块容易因为大雪堆积或强风的影响产生弯曲变形的情况。太阳能模块弯曲变形会产生破坏太阳能模块内部的太阳能电池的内应力，进而降低太阳能电池的转换效率及缩短太阳能电池使用寿命。因此，当太阳能模块受到外力作用时，如何在太阳能模块受到外力作用时尽可能地降低太阳能模块的最大内应力强度，进而提高太阳能电池的转换效率及延长太阳能电池使用寿命。However, in high latitude areas or areas where strong winds often occur, solar modules are prone to bending and deformation due to heavy snow accumulation or strong winds. The bending deformation of the solar module will generate internal stress that damages the solar cells inside the solar module, thereby reducing the conversion efficiency of the solar cells and shortening the service life of the solar cells. Therefore, when the solar module is subjected to an external force, how to reduce the maximum internal stress intensity of the solar module as much as possible to improve the conversion efficiency of the solar cell and prolong the service life of the solar cell.
发明内容Contents of the invention
本发明在于提供一种太阳能光电系统，借以在太阳能板受到外力作用时尽可能地降低太阳能板的最大内应力强度，进而提高太阳能电池的转换效率及延长太阳能电池使用寿命。The present invention is to provide a solar photovoltaic system, so as to reduce the maximum internal stress intensity of the solar panel as much as possible when the solar panel is subjected to external force, thereby improving the conversion efficiency of the solar cell and prolonging the service life of the solar cell.
本发明所揭示的太阳能光电系统，包含至少一固定架、一太阳能模块及一缓冲垫。太阳能模块位于至少一固定架上。缓冲垫位于固定架与太阳能模块之间。缓冲垫具有一凹凸曲面。凹凸曲面面向太阳能模块。The solar photovoltaic system disclosed by the present invention includes at least one fixing frame, a solar module and a cushion. The solar module is located on at least one fixing frame. The buffer pad is located between the fixing frame and the solar module. The buffer pad has a concave-convex surface. The concave-convex surface faces the solar module.
根据上述本发明所揭示的太阳能光电系统，由于缓冲垫设置于固定架与太阳能模块之间，太阳能模块朝固定架的方向弯曲时，太阳能模块会和缓冲垫接触。当太阳能模块的背板和缓冲垫接触时，缓冲垫会分散外力，以令太阳能模块的内应力能够分散至内应力强度较小的部位。如此一来，缓冲垫可降低太阳能模块的最大内应力强度及平均内应力强度，进而提高太阳能光电系统的转换效率及延长太阳能光电系统的使用寿命。According to the solar photovoltaic system disclosed in the present invention, since the buffer pad is disposed between the fixing frame and the solar module, when the solar module bends toward the fixing frame, the solar module will contact the buffer pad. When the backplane of the solar module is in contact with the buffer pad, the buffer pad will disperse the external force, so that the internal stress of the solar module can be distributed to the parts with less internal stress intensity. In this way, the buffer pad can reduce the maximum internal stress intensity and the average internal stress intensity of the solar module, thereby improving the conversion efficiency of the solar photovoltaic system and prolonging the service life of the solar photovoltaic system.
以上关于本发明内容的说明及以下实施方式的说明用以示范与解释本发明的原理，并且提供本发明的权利要求书更进一步的解释。The above descriptions about the contents of the present invention and the following descriptions of the embodiments are used to demonstrate and explain the principles of the present invention, and provide further explanations of the claims of the present invention.

请参照图1与图2A。图1为根据本发明第一实施例的太阳能光电系统的立体剖面示意图。图2A为图1的剖面示意图。Please refer to FIG. 1 and FIG. 2A. FIG. 1 is a schematic three-dimensional cross-sectional view of a solar photovoltaic system according to a first embodiment of the present invention. FIG. 2A is a schematic cross-sectional view of FIG. 1 .
本实施例的太阳能光电系统10包含一固定架100、一太阳能模块200、两个夹持件300、两个结合件400及一缓冲垫500。The solar photovoltaic system 10 of this embodiment includes a fixing frame 100 , a solar module 200 , two clamping components 300 , two coupling components 400 and a buffer pad 500 .
太阳能模块200包含一玻璃210、一太阳能电池220及一背板230。太阳能电池220叠设于玻璃210与背板230之间。背板230较玻璃210靠近固定架100。The solar module 200 includes a glass 210 , a solar cell 220 and a back plate 230 . The solar cell 220 is stacked between the glass 210 and the back plate 230 . The back plate 230 is closer to the fixing frame 100 than the glass 210 .
两个夹持件300分别可活动地设于固定架100。太阳能模块200夹设于夹持件300之间。The two clips 300 are respectively movably disposed on the fixing frame 100 . The solar module 200 is sandwiched between the clips 300 .
两个结合件400分别穿设夹持件300及固定架100，以将太阳能模块200固定于固定架100上方。The two connecting parts 400 pass through the clamping part 300 and the fixing frame 100 respectively, so as to fix the solar module 200 above the fixing frame 100 .
缓冲垫500位于固定架100与太阳能模块200之间，并接触于固定架100。缓冲垫500具有一凹凸曲面510。凹凸曲面510面向太阳能模块200的背板230，且与背板230保持一间距H。其中，缓冲垫500的材质为胶带、硅胶或橡胶。The buffer pad 500 is located between the fixing frame 100 and the solar module 200 , and is in contact with the fixing frame 100 . The buffer pad 500 has a concave-convex surface 510 . The concave-convex curved surface 510 faces the backplane 230 of the solar module 200 and maintains a distance H from the backplane 230 . Wherein, the cushion pad 500 is made of adhesive tape, silica gel or rubber.
在本实施例中，缓冲垫500为双峰式，进一步来说，凹凸曲面510具有两个凸出段520，且两个凸出段520位于凹凸曲面510的相对两端。而凹凸曲面510的曲面方程式为：In this embodiment, the buffer pad 500 is bimodal. Further, the concave-convex surface 510 has two protruding segments 520 , and the two protruding segments 520 are located at opposite ends of the concave-convex surface 510 . And the surface equation of the concave-convex surface 510 is:
y＝-Ε-15x6+4Ε-12x5-6Ε-9x4+6Ε-6x3-0.0025x2+0.439x-0.0593(1)y=-E -15 x 6 +4E -12 x 5 -6E -9 x 4 +6E -6 x 3 -0.0025x 2 +0.439x-0.0593(1)
在本实施例及其它实施例中，缓冲垫500具有相对两端缘。缓冲垫500的两端缘分别与两个夹持件300保持一距离D。距离D介于4.5mm与5mm。In this embodiment and other embodiments, the buffer pad 500 has two opposite edges. The two ends of the buffer pad 500 maintain a distance D from the two clips 300 respectively. The distance D is between 4.5mm and 5mm.
请参照图2B。图2B为图1的太阳能光电系统的太阳能模块遭受外力而变形的剖面示意图。Please refer to Figure 2B. FIG. 2B is a schematic cross-sectional view of the deformation of the solar module of the solar photovoltaic system of FIG. 1 subjected to an external force.
由于缓冲垫500设置于固定架100与太阳能模块200之间，故太阳能模块200在外力F作用下朝固定架100的方向弯曲时，太阳能模块200的背板230会和双峰式缓冲垫500接触。当太阳能模块200的背板230和双峰式缓冲垫500接触时，双峰式缓冲垫500会全面均匀分散外力，以令太阳能模块200的内应力能够分散至外力作用点周边内应力强度较小的部位。Since the buffer pad 500 is arranged between the fixed frame 100 and the solar module 200, when the solar module 200 bends toward the fixed frame 100 under the action of an external force F, the back plate 230 of the solar module 200 will be in contact with the bimodal buffer pad 500 . When the back plate 230 of the solar module 200 is in contact with the bimodal buffer pad 500, the bimodal buffer pad 500 will fully and evenly disperse the external force, so that the internal stress of the solar module 200 can be dispersed to the point where the external force acts and the surrounding internal stress intensity is small parts.
分别将无设置缓冲垫500的太阳能光电系统与本实施例设置有双峰式缓冲垫500的太阳能光电系统10进行计算机仿真。其模拟结果请参照图2C与图2D。图2C为图1的太阳能光电系统无设置缓冲垫的模拟示意图。图2D为图1的太阳能光电系统有设置缓冲垫的模拟示意图。如图2C所示，无设置缓冲垫500的太阳能光电系统10的背板230的最大内应力发生在靠近四个角落处，其最大内应力强度为55-60MPa，而背板的平均内应力强度为45-50MPa。反观，如图2D所示，设置有双峰式缓冲垫500的太阳能光电系统10的背板230产生最大内应力的位置自背板230的四个角落略为内移，且其最大应力强度降为45MPa，以及背板230的平均内应力强度降为30-40MPa。Computer simulations were performed on the solar photovoltaic system without the buffer pad 500 and the solar photovoltaic system 10 provided with the bimodal buffer pad 500 in this embodiment. For the simulation results, please refer to FIG. 2C and FIG. 2D . FIG. 2C is a schematic diagram of the simulation of the solar photovoltaic system in FIG. 1 without a buffer pad. FIG. 2D is a simulated schematic diagram of the solar photovoltaic system in FIG. 1 with a buffer pad. As shown in Figure 2C, the maximum internal stress of the back plate 230 of the solar photovoltaic system 10 without the buffer pad 500 occurs near the four corners, and its maximum internal stress intensity is 55-60MPa, while the average internal stress intensity of the back plate 45-50MPa. In contrast, as shown in FIG. 2D , the position where the maximum internal stress is generated on the back plate 230 of the solar photovoltaic system 10 provided with the bimodal buffer pad 500 is slightly moved inward from the four corners of the back plate 230, and its maximum stress intensity is reduced to 45MPa, and the average internal stress intensity of the back plate 230 is reduced to 30-40MPa.
从计算机仿真数据可知，双峰式缓冲垫500的设置将可有效降低太阳能模块200的最大内应力强度以及平均内应力强度，进而提高太阳能光电系统10的转换效率及延长太阳能光电系统10的使用寿命。From the computer simulation data, it can be seen that the setting of the bimodal buffer pad 500 can effectively reduce the maximum internal stress intensity and the average internal stress intensity of the solar module 200, thereby improving the conversion efficiency of the solar photovoltaic system 10 and prolonging the service life of the solar photovoltaic system 10 .
本实施例的缓冲垫500设置于固定架100与太阳能模块200之间除了有上述优点之外，更有(1)结构简单，易制造；(2)成本低廉(胶带、硅胶或橡胶)；(3)藏于固定架100与太阳能模块200之间，故不会影响太阳能光电系统10的外观及散热效果等优点。In addition to the above advantages, the buffer pad 500 of this embodiment is arranged between the fixed frame 100 and the solar module 200, and has (1) simple structure and easy manufacture; (2) low cost (adhesive tape, silica gel or rubber); 3) It is hidden between the fixing frame 100 and the solar module 200 , so it will not affect the appearance and heat dissipation effect of the solar photovoltaic system 10 .
上述缓冲垫500的形状并不限于双峰式，在其它实施例中，缓冲垫500的形状也可以是其它几何形状。请参照图3A。图3A为根据本发明第二实施例的太阳能光电系统的剖面示意图。The shape of the cushion pad 500 is not limited to bimodal, and in other embodiments, the shape of the cushion pad 500 can also be other geometric shapes. Please refer to Figure 3A. 3A is a schematic cross-sectional view of a solar photovoltaic system according to a second embodiment of the present invention.
本实施例与上述实施例的主要差异在于缓冲垫500a为单峰式。进一步来说，缓冲垫500a的凹凸曲面510a具有一凸出段520a，且凸出段520a位于凹凸曲面510a的中央位置。而凹凸曲面510a的曲面方程式为：The main difference between this embodiment and the above-mentioned embodiments is that the buffer pad 500a is a single-peak type. Further, the concave-convex surface 510a of the buffer pad 500a has a protruding section 520a, and the protruding section 520a is located at the center of the concave-convex surface 510a. And the surface equation of the concave-convex surface 510a is:
y＝6Ε-11x4-Ε-7x3-2Ε-5x2+0.0635x+10.048(2)y=6E -11 x 4 -E -7 x 3 -2E -5 x 2 +0.0635x+10.048(2)

Please refer to FIG. 3B for the simulation results. FIG. 3B is a schematic simulation diagram of the solar photovoltaic system in FIG. 3A . As shown in Fig. 3B, the position where the back plate 230 of the solar photovoltaic system 10 with the unimodal buffer pad 500a produces the maximum internal stress moves from the four corners of the back plate 230 to the opposite ends of the lower glass, and the position of the present embodiment The maximum internal stress intensity of the back plate 230 of the solar photovoltaic system 10 is 45 MPa (less than 55 MPa), and the average internal stress intensity of the back plate 230 is 35-40 MPa (less than 45 MPa).

Furthermore, the surface equation of the concave-convex surface 510b is:
y＝3Ε-15x6-8Ε-12x5+7Ε-9x4-3Ε-6x3+0.0002x2-0.0174x+25.982(3)y=3E -15 x 6 -8E -12 x 5 +7E -9 x 4 -3E -6 x 3 +0.0002x 2 -0.0174x+25.982(3)

Please refer to FIG. 4B for the simulation results. FIG. 4B is a schematic simulation diagram of the solar photovoltaic system shown in FIG. 4A .

请参照图5A。图5A为根据本发明第四实施例的太阳能光电系统的剖面示意图。Please refer to Figure 5A. 5A is a schematic cross-sectional view of a solar photovoltaic system according to a fourth embodiment of the present invention.
本实施例与上述实施例的主要差异在于缓冲垫500c为三峰式。进一步来说，缓冲垫500c的凹凸曲面510c的凸出段520的数量为三个。详细来说，凹凸曲面510c具有两个第一凸出段540及一个第二凸出段550。两个第一凸出段540分别位于凹凸曲面510c的相对两端，第二凸出段550位于两个第一凸出段540之间。并且第一凸出段540凸出于固定架100的高度大于第二凸出段550凸出于固定架100的高度。而凹凸曲面510c的半边曲面方程式为：The main difference between this embodiment and the above-mentioned embodiments is that the buffer pad 500c is a three-peak type. Further, the number of the protruding sections 520 of the concave-convex curved surface 510c of the buffer pad 500c is three. In detail, the concave-convex surface 510c has two first protruding segments 540 and one second protruding segment 550 . The two first protruding sections 540 are respectively located at opposite ends of the concave-convex curved surface 510c, and the second protruding section 550 is located between the two first protruding sections 540 . And the height of the first protruding section 540 protruding from the fixing frame 100 is greater than the height of the second protruding section 550 protruding from the fixing frame 100 . And the half-side surface equation of the concave-convex surface 510c is:

将本实施例设置有三峰式缓冲垫500的太阳能光电系统10进行计算机仿真。其模拟结果请参照图5B。图5B为图5A的太阳能光电系统的仿真示意图。如图5B所示，设置有三峰式缓冲垫500c的太阳能光电系统10的背板230产生最大内应力的位置自背板230的四角落略为内移，且本实施例的太阳能光电系统10的背板230的最大内应力强度为40MPa(小于55MPa)，而背板230的平均内应力强度为25-35MPa(小于45MPa)。The solar photovoltaic system 10 provided with the tri-peak cushion 500 in this embodiment is subjected to computer simulation. Please refer to FIG. 5B for the simulation results. FIG. 5B is a schematic simulation diagram of the solar photovoltaic system in FIG. 5A . As shown in Fig. 5B, the position where the back plate 230 of the solar photovoltaic system 10 with the three-peak buffer pad 500c generates the maximum internal stress is slightly moved inward from the four corners of the back plate 230, and the back plate 230 of the solar photovoltaic system 10 in this embodiment The maximum internal stress intensity of the plate 230 is 40MPa (less than 55MPa), while the average internal stress intensity of the back plate 230 is 25-35MPa (less than 45MPa).
比较上述各实施例的仿真数据与无设置缓冲垫500c的太阳能光电系统10，三峰式缓冲垫500c具有较佳的内应力分散能力(与无设置缓冲垫500c的太阳能光电系统10相比，设置有三峰式缓冲垫500c的太阳能光电系统10的平均内应力强度最大衰减比例达22％以及较佳的降低内应力强度的能力(与无设置缓冲垫500c的太阳能光电系统相比，设置有三峰式缓冲垫500c的太阳能光电系统10的最大内应力强度最大衰减比例达27％。Comparing the simulation data of each of the above-mentioned embodiments with the solar photovoltaic system 10 without the buffer pad 500c, the three-peak buffer pad 500c has better internal stress dispersion capability (compared with the solar photovoltaic system 10 without the buffer pad 500c, which is provided with The maximum attenuation ratio of the average internal stress intensity of the solar photovoltaic system 10 of the three-peak buffer pad 500c reaches 22% and preferably reduces the ability of the internal stress intensity (compared with the solar photovoltaic system without the buffer pad 500c, the three-peak buffer is provided. The maximum attenuation ratio of the maximum internal stress intensity of the solar photovoltaic system 10 of the pad 500c reaches 27%.
根据上述本发明所揭示的太阳能光电系统，由于缓冲垫设置于固定架与太阳能模块之间，太阳能模块朝固定架的方向弯曲时，太阳能模块会和缓冲垫接触。当太阳能模块的背板和缓冲垫接触时，缓冲垫会分散外力，以令太阳能模块的内应力能够分散至外力作用点周边内应力强度较小的部位。如此一来，缓冲垫可降低太阳能模块的最大内应力强度及平均内应力强度，进而提高太阳能光电系统的转换效率及延长太阳能光电系统的使用寿命。According to the solar photovoltaic system disclosed in the present invention, since the buffer pad is disposed between the fixing frame and the solar module, when the solar module bends toward the fixing frame, the solar module will contact the buffer pad. When the backplane of the solar module is in contact with the buffer pad, the buffer pad will disperse the external force, so that the internal stress of the solar module can be dispersed to the parts with less internal stress intensity around the point where the external force acts. In this way, the buffer pad can reduce the maximum internal stress intensity and the average internal stress intensity of the solar module, thereby improving the conversion efficiency of the solar photovoltaic system and prolonging the service life of the solar photovoltaic system.
