Description

Technical Field

[0001] The utility model relates to solar panels, and in particular to a power generation system composed of solar panels. Background Art

[0002] Electricity is an indispensable source of power in today's lives. Traditional power generation methods rely on coal or gas, which produces air pollution and accelerates global warming. While nuclear power generation does not have these drawbacks, nuclear waste remains difficult to properly dispose of. Therefore, humanity continues to seek clean energy sources, or green energy, that generate electricity without damaging the environment or producing waste that cannot be properly disposed of. Solar energy is one such source. Solar power generation primarily utilizes sunlight energy. Semiconductor materials installed on solar panels illuminated by sunlight transfer the sunlight's energy to electrons, creating free electrons and holes. Under the action of an internal or external electric field, this energy generates an electric current, effectively converting sunlight energy into electrical energy.

[0003] Conventional solar panels are installed with the light-receiving surface facing upward, tilted at a 5-30 degree angle to the installation surface (e.g., rooftop or ground). Besides utilizing previously unused space on rooftops, solar panels are now being installed in areas such as aquaculture and agriculture, utilizing space above farmland or fish ponds to generate electricity. However, when installing solar panels above farmland or fish ponds, concerns arise about shading, which can reduce sunlight exposure to crops and aquatic products below. Therefore, regulations stipulate that the vertical projection area occupied by solar panels must not exceed a specific percentage. For example, in aquaculture zones, the required coverage ratio is 40%. For example, only 0.4 hectares of solar panels can be installed on 1 hectare of land. This limits the number of solar panels that can be installed within a given area. Therefore, how to install more solar panels within a limited area while not affecting the growth of crops and aquatic products has become a key issue in the development of solar power plants. Summary of the Invention

[0004] In view of this, the present invention is to improve the existing solar power station, so as to provide a solar power station in which solar panels are arranged at a higher density within a limited area without affecting the growth of crops and aquatic products.

[0005] To achieve the aforementioned objectives, the present invention provides a high-density solar power generation system comprising a plurality of power generation components arranged in multiple rows and columns, wherein each power generation component comprises:

[0006] A support frame, which is in a plane perpendicular to the field in which it is set, and includes a frame body with at least one accommodating space formed therein;

[0007] At least one solar power generation module is fixedly installed in the corresponding accommodating space of the frame, and each solar power generation module is perpendicular to the plane of the set field. The different two sides of each solar power generation module are respectively a first light receiving surface and a second light receiving surface. The first light receiving surface and the second light receiving surface are both provided with semiconductor materials that can convert light energy into electrical energy. The first light receiving surface and the second light receiving surface are perpendicular to the plane of the set field.

[0008] The advantage of the present invention is that by vertically arranging solar power generation modules, the vertical projection area occupied is reduced, thereby effectively reducing the land area required for use, so as to pursue the installation of a higher density of power generation components in a limited area, and the shading problem can be reduced, thereby significantly reducing the impact of the installation of solar power generation modules on the growth of crops and aquatic products.

[0021] The following is in conjunction with the accompanying drawings and embodiments of the present invention to further explain the technical means adopted by the present invention to achieve the predetermined new purpose. The drawings have been simplified for illustrative purposes only, and the structure or method of the present invention is explained by describing the relationship between the elements and components of the present invention. Therefore, the elements shown in the drawings are not presented in actual quantity, actual shape, actual size and actual proportion. The size or size proportion has been enlarged or simplified to provide a better explanation. The actual quantity, actual shape or actual size proportion has been selectively designed and configured, and the detailed element layout may be more complicated.

[0022] See also Figures 1 to 3 As shown, the high-density solar power generation system of the present invention includes a plurality of power generation components 10 arranged in multiple rows and columns. Each power generation component 10 includes a support frame 20 and at least one solar power generation module 30.

[0023] The support frame 20 is perpendicular to the plane of the installation site (e.g., the ground of farmland or the surface of a fish pond). It comprises a frame 21 and a plurality of columns 22. The columns 22 are spaced apart at the bottom of the frame 21 to support the frame 21. The frame 21 is formed with at least one accommodating space 211. The size of the columns 22 can be determined by the requirements of the installation environment. For example, columns 22 used in a fish pond will be longer than those used in farmland; columns 22 used in a site with strong winds will be thicker than those used in a site with weaker winds.

[0024] Each solar power generation module 30 is fixedly installed in a corresponding accommodating space 211 and is perpendicular to the plane of the field in which it is installed (for example, the ground of farmland, the water surface of a fish pond). Different sides of each solar power generation module 30 are respectively a first light-receiving surface 31 and a second light-receiving surface 32. The first light-receiving surface 31 and the second light-receiving surface 32 are perpendicular to the plane of the field in which they are installed. The first light-receiving surfaces 31 and the second light-receiving surfaces 32 of the solar power generation modules 30 located in the same row are aligned. The first light-receiving surfaces 31 and the second light-receiving surfaces 32 are both provided with semiconductor materials that can convert light energy into electrical energy. Therefore, no matter which side the sunlight shines on the solar power generation module 30, the light energy can be received by the first light-receiving surface 31 or the second light-receiving surface 32 and converted into electrical energy. Please refer to Figure 6 As shown, when sunlight is irradiated from the right side, the first light-receiving surface 31 of each solar power generation module 30 is irradiated by the sunlight, thereby generating power generation benefits; Figure 7As shown, when sunlight shines from the left side, the second light-receiving surface 32 of each solar power generation module 30 is illuminated by the sunlight, generating electricity. In one embodiment, each solar power generation module 30 comprises two solar panels placed flush with each other to form the first light-receiving surface 31 and the second light-receiving surface 32. In another embodiment, each solar power generation module 30 comprises a single solar panel to form both the first light-receiving surface 31 and the second light-receiving surface 32.

[0025] The number, shape and arrangement of the accommodating space 211 of the frame 21 and the solar power generation modules 30 can be set as required. Figure 4 As shown, in one embodiment, the frame 21 has two accommodating spaces 211 in each row and four accommodating spaces 211 in each row, and the shape of the solar power generation module 30 is matched with the shape and number of the accommodating spaces 211; Figure 5 As shown, in another embodiment, the frame 21A has one accommodating space 211A in each row and eight accommodating spaces 211A in each horizontal row, and the shape of the solar power generation module 30A is matched with the shape and number of the accommodating spaces 211A.

[0026] Taking into account the possible mutual influence of the shadows 40 between the power generation components 10 in adjacent rows, in order to prevent the shadows of the power generation components 10 from shading the power generation components 10 in adjacent rows, the ratio of the distance D between the power generation components 10 in adjacent rows and the height H of each support frame 20 can be adjusted according to the area in which they are installed, for example, H:D = 1:1, 1:2, 1:3... etc., weighing the shadow shielding effect and the ability to install more power generation components 10 in a limited area. In one embodiment, considering the sunlight angle when installed in an area of ​​22 to 25 degrees north latitude (such as Taiwan, China), the optimal ratio is H:D = 1:1.45.

[0027] by Figure 2 As an example, assuming that the height H, length L = 3H, and thickness t = 0.01H of each support 20, the length and width of the field are 100H and the area size is 10000H. 2 As an example, let's calculate the high-density solar power generation system of the present invention. Based on a spacing of 1.45H, a width of 100H can accommodate 68 rows and 33 columns, totaling 2,244 groups of power generation components 10. The vertical projection area occupied by each group is L*t=0.03H. 2 , then a total of 67H 2 The vertical projection area of ​​​​the solar panel is 40% of the upper limit, as shown in the above regulations. 2 Still not reaching 4000H 2, but it is already possible to effectively install up to 2244 sets of power generation components 10. Furthermore, since each solar power generation module 30 can generate electricity on both sides (having a first light-receiving surface 31 and a second light-receiving surface 32), 2244 sets of power generation components 10 are equivalent to 4488 sets of traditional single-sided power generation. Furthermore, if the same size power generation components are installed using the traditional installation method, assuming an elevation angle of 30 degrees, the length of the orthographic projection area occupied remains unchanged at 3H, but the ratio of the width W of the orthographic projection area to the height H is:

[0028]

[0029] Therefore, the width W is about 0.886H, and the vertical projection area required for a single group of laying is 0.886H*3H=2.658H 2 Therefore, if the maximum can only be laid 4000H 2 Calculated from the total area, the traditional method can only lay 1505 groups, which is far less than the 2244 groups that can be laid by the new method. Furthermore, if the traditional method is used to lay 2244 groups, it will take up about 5965H 2 The vertical projection area is much higher than the 67H required by this new model. 2 The vertical projection area of

[0030] Therefore, the high-density solar power generation system designed by the present invention can effectively utilize land resources and set up a higher density of power generation components 10 while occupying a very small area of ​​land. While occupying a very small area of ​​land, it can also greatly reduce the problem of shading, so that the farmland and fish ponds where they are set up can still obtain sufficient sunlight, and the impact on the growth of crops and aquatic products can be effectively reduced. In addition, the small area of ​​land occupied can also make it easy for large machinery to enter the operation, such as the large machinery required for harvesting crops, which can effectively reduce the impact of the solar power generation system on the efficiency of the operation. Furthermore, the solar power generation module 30 perpendicular to the plane of the field where it is set up can greatly reduce the probability of pollutants (such as dust, bird droppings, etc.) accumulating on it, thereby reducing the loss of power generation efficiency due to the accumulation of pollutants, thereby maintaining effective power generation, and reducing the need for fixed cleaning cycles.
