Description

[0002] Photovoltaic power generation technology, as a technical solution for producing clean energy using solar energy, is widely used in energy supply, environmental protection, and temporary power facilities.

[0003] Currently, most flexible photovoltaic (PV) power stations on the market are mainly used in sparsely populated areas such as mountains, fishponds, and sewage treatment plants. Flexible PV power stations typically use a steel column structure with a concrete foundation as the supporting base. Support strands are stretched between the steel columns to form a flexible suspension structure, and photovoltaic panels are fixed to the support strands to form a large-span PV array.

[0004] The steel column structure used in the aforementioned flexible photovoltaic power stations requires complex civil engineering construction, resulting in time-consuming and labor-intensive installation and dismantling, making rapid relocation or redeployment difficult. This limits their suitability for temporary or flexible applications in densely populated areas such as parks and plazas. Furthermore, the photovoltaic panels in these flexible power stations are fixed to the support strands using conventional connectors, leading to insufficient connection stability. This makes them prone to loosening or detachment due to wind loads or vibrations, thus affecting the photovoltaic power generation performance of the flexible photovoltaic power station.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0043] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0044] Figure 1 This is a structural schematic diagram of a flexible photovoltaic power station provided in an embodiment of this utility model. Figure 1 As shown, the flexible photovoltaic power station includes: multiple container groups 1, each container group 1 including two containers 11 arranged opposite each other along a first direction X; a flexible photovoltaic structure 2, including multiple photovoltaic panels 21 arranged in an array; a photovoltaic support structure 3, including multiple support strands 31 arranged sequentially along a second direction Y; the two ends of the support strands 31 are respectively fixed to the two containers 11 of the same container group 1; the second direction Y intersects with the first direction X; a fastening structure 4, through which the photovoltaic panels 21 are fixed to the support strands 31; the multiple photovoltaic panels 21 constitute multiple photovoltaic panel assemblies 22 arranged along the second direction Y; the photovoltaic panel assembly 22 includes multiple photovoltaic panels 21 arranged along the first direction X; the same photovoltaic panel assembly 22 is fixed to two adjacent support strands 31.

[0045] The container group 1 consists of two containers 11 arranged opposite each other along the first direction X, serving as the supporting foundation for the flexible photovoltaic power station. Compared to traditional steel column structures with concrete foundations, the container group 1 does not require ground fixation; it is secured by adding counterweights within the container group 1. This facilitates the rapid installation and dismantling of the flexible photovoltaic power station, enhancing its operational flexibility. Simultaneously, the containers 11 within the container group 1 can also serve as transport packaging, integrating various components of the flexible photovoltaic power station, such as photovoltaic panels 21, support strands 31, and fastening structures 4, facilitating the overall transportation of the flexible photovoltaic power station to the installation site. Furthermore, after the flexible photovoltaic power station is installed, the internal space of the containers 11 can be configured as offices, warehouses, or rest areas to increase space utilization and expand the application scenarios of the flexible photovoltaic power station.

[0046] The flexible photovoltaic structure 2 includes multiple photovoltaic panels 21 arranged in an array. These photovoltaic panels 21 convert solar energy into electrical energy to realize the photovoltaic power generation function of the flexible photovoltaic power station. For example, the photovoltaic panels 21 may include monocrystalline silicon photovoltaic panels, polycrystalline silicon photovoltaic panels, or perovskite photovoltaic panels, etc. The multiple photovoltaic panels 21 are arranged along a second direction Y intersecting the first direction X to form multiple photovoltaic panel modules 22. Each photovoltaic panel module 22 includes multiple photovoltaic panels 21 arranged along the first direction X, enabling the formation of an ordered and large-area photovoltaic array, thereby optimizing the solar energy capture efficiency of the flexible photovoltaic power station and improving its photovoltaic power generation performance.

[0047] The photovoltaic support structure 3 includes multiple support strands 31, with both ends of each strand fixed to two containers 11 of the same container group 1. Prestress is applied to the support strands 31 to stretch them into a suspension structure to support the photovoltaic panels 21. For example, the support strands 31 may include six bundles of 7-gauge plastic-coated steel strands. Each support strand 31 and each row of photovoltaic panel components 31 are arranged along the second direction Y, allowing the multiple support strands 31 to serve as a large-span fixing carrier for the multiple photovoltaic panel components 31. This maximizes the photovoltaic power generation area of ​​the flexible photovoltaic power station while maintaining available ground space.

[0048] The fastening structure 4 is used to fix the photovoltaic panel 21 to the support strand 31, ensuring a stable connection between the photovoltaic panel 21 and the support strand 31, thereby ensuring the stability of the photovoltaic array in the flexible photovoltaic power station. The fastening structure 4 can disperse external forces such as wind load and vibration, thereby reducing the risk of the photovoltaic panel 21 loosening or falling off, and ensuring the long-term stable operation of the flexible photovoltaic power station. For example, the fastening structure 4 may include clamping buckles, hook-type connectors, or magnetic fasteners. In addition, the fastening structure 4 can fix the same photovoltaic panel assembly 22 to two adjacent support strands 31. The cooperative support of the two support strands 31 ensures the firmness of the connection between the photovoltaic panel assembly 22 and the support strands 31. At the same time, the fixing method of the two support strands 31 ensures the geometric stability of the photovoltaic panel assembly 22 in the horizontal and vertical directions, avoiding the torsion or tilting that may occur when the photovoltaic panel assembly 22 is fixed by a single support strand 31, improving the light reception uniformity of the photovoltaic array, and thus optimizing the photovoltaic power generation performance of the flexible photovoltaic power station.

[0049] In this embodiment, multiple container groups are set up in the flexible photovoltaic power station, with two containers arranged opposite each other along a first direction within each group. These container groups serve as the supporting foundation for the flexible photovoltaic power station, facilitating rapid installation and dismantling, improving its flexibility, and expanding its application scenarios. Multiple photovoltaic panels are arranged in an array within the flexible photovoltaic structure to achieve photovoltaic power generation. By arranging these panels along a second direction intersecting the first direction, multiple photovoltaic panel modules can be formed, including the panels arranged along the first direction. This creates an orderly and large-area photovoltaic array, optimizing the solar energy capture efficiency of the flexible photovoltaic power station. Furthermore, multiple support strands arranged sequentially along the second direction are set up in the photovoltaic support structure, with both ends fixed to two containers within the same container group. These support strands serve as a large-span fixing carrier for the multiple photovoltaic panel modules, maximizing the photovoltaic power generation area of ​​the flexible photovoltaic power station. By using a fastening structure to fix the same photovoltaic panel module to two adjacent support strands, the robustness of the connection between the photovoltaic panel module and the support strands is ensured. At the same time, the geometric stability of the photovoltaic panel module in the horizontal and vertical directions is ensured, the light reception consistency of the photovoltaic array is improved, and thus the photovoltaic power generation performance of the flexible photovoltaic power station is optimized.

[0050] Optional, Figure 2 This is a structural schematic diagram of a photovoltaic panel provided in an embodiment of this utility model. (See diagram below.) Figure 2 As shown, the photovoltaic panel 21 includes a photovoltaic panel 211 and a photovoltaic frame 212 for accommodating the photovoltaic panel 211; the photovoltaic frame 212 includes at least one set of pre-made holes 213; each set of pre-made holes 213 includes two pre-made holes 214; the fastening structure 4 includes a plurality of U-shaped fasteners 41; the support stranded wire 31 is clamped in the U-shaped fasteners 41, and both ends of the U-shaped fasteners 41 pass through the same set of pre-made holes 213.

[0051] Specifically, the photovoltaic panel 21 includes a photovoltaic panel 211 and a photovoltaic frame 212, with the frame 212 accommodating the panel 211. For example, the photovoltaic panel 211 may include a composite fiber material to reduce its weight, thereby reducing the pressure on the support strands 31 and the container 11, enhancing the stability of the large-span design of the flexible photovoltaic power station. Simultaneously, the composite fiber material has excellent impact resistance; compared to traditional glass-based photovoltaic modules, it significantly reduces the risk of breakage of the photovoltaic panel 211 and extends its service life. The photovoltaic frame 212 can be bonded to the photovoltaic panel 211 using structural sealant, ensuring the structural stability of the panel 211. The frame 212 may also include composite fiber materials, such as polyurethane composites. Polyurethane composite materials possess high strength and stiffness, providing reliable structural support for the photovoltaic panel 211 and preventing deformation of the photovoltaic panel 211 within the photovoltaic support structure 3 due to tension or external forces. Simultaneously, polyurethane composite materials exhibit excellent resistance to damp heat, acids and alkalis, and salt spray, ensuring the flexible photovoltaic power station can be used under various climatic conditions and expanding its application scenarios. Furthermore, the high strength and toughness of the polyurethane composite material ensure that the photovoltaic frame 212 maintains its mechanical properties even after pre-drilling holes 213 in the frame. This allows for a stable connection between the photovoltaic panel 21 and the support stranded wire 31 through the pre-drilled holes 213 and the fastening structure 4, while ensuring the structural stability of the photovoltaic panel 21.

[0052] The fastening structure 4 includes multiple U-shaped fasteners 41, which, for example, may include U-shaped screws. Each set of pre-drilled holes 213 includes two pre-drilled holes 214. The distance between the two pre-drilled holes 214 and the size of the pre-drilled holes 214 are correspondingly set to the distance between the two ends of the U-shaped fastener 41 and the size of the two ends of the U-shaped fastener 41, so that the support strand 31 can be locked in the U-shaped fastener 41. Both ends of the U-shaped fastener 41 can pass through the two pre-drilled holes 214 in the same pre-drilled hole 213 of the photovoltaic frame 212. After the two ends of the U-shaped fastener 41 pass through the two pre-drilled holes 214, they can be threaded and fixed by nuts, thereby achieving a firm connection between the photovoltaic panel 21 and the support strand 31. This ensures that the photovoltaic panel 21 will not loosen or fall off under wind load or vibration, improving the durability and safety of the flexible photovoltaic power station.

[0053] Optional, Figure 3 This is a schematic diagram of another photovoltaic panel structure provided in an embodiment of the present invention, as shown below. Figure 3As shown, the photovoltaic frame 212 includes two sets of pre-made holes 213 located on opposite sides of the photovoltaic frame 212 along the second direction Y; two adjacent support strands 31 supporting the same photovoltaic panel 21 constitute a support strand group; the two support strands 31 of the same support strand group are respectively locked in two U-shaped fasteners 41, and the two ends of the two U-shaped fasteners 41 respectively pass through the two sets of pre-made holes 213 of the same photovoltaic frame 212.

[0054] Specifically, the photovoltaic frame 212 includes two sets of pre-drilled holes 213 located on opposite sides of the photovoltaic frame 212 along the second direction Y, so that the same photovoltaic panel assembly 22 can be fixed to two adjacent support strands 31 by U-shaped fasteners 41. For example, the two adjacent support strands 31 can be a first support strand and a second support strand, forming a support strand group. Each photovoltaic panel 21 in the same photovoltaic panel assembly 22 will also have two sets of pre-drilled holes 213 correspondingly provided, namely a first sub-pre-drilled hole group and a second sub-pre-drilled hole group. The first sub-pre-drilled hole group and the second sub-pre-drilled hole group are located on opposite sides of the photovoltaic frame 212 along the second direction Y, so that the photovoltaic panel 21 can be fixed by two U-shaped fasteners 41, namely a first U-shaped fastener and a second U-shaped fastener. The first support strand is secured in the first U-shaped fastener, with both ends of the first U-shaped fastener passing through two pre-drilled holes in the first sub-pre-drilled hole group and threadedly connected to the nut. The second support strand is secured in the second U-shaped fastener, with both ends of the second U-shaped fastener passing through two pre-drilled holes in the second sub-pre-drilled hole group and threadedly connected to the nut. This allows the same photovoltaic panel assembly 22 to be fixed to two adjacent support strands 31. The two adjacent support strands 31 provide multiple fixing points for the photovoltaic panel assembly 22, thereby enhancing the load-bearing capacity and stability of the suspension photovoltaic structure, avoiding possible torsion or tilting of the photovoltaic panel assembly 22 when fixed by a single support strand 31, improving the light reception consistency of the photovoltaic array, and thus optimizing the photovoltaic power generation performance of the flexible photovoltaic power station.

[0055] Optional, Figure 4 This is a schematic diagram of another flexible photovoltaic power station provided by this utility model embodiment. The container 11 includes a plurality of prefabricated fixing parts 12 arranged at intervals along the second direction Y; the two ends of the support strand 31 are respectively fixed to two opposite containers 11 in the same container group 1 by the prefabricated fixing parts 12.

[0056] Specifically, the prefabricated fastener 12 provides a connection interface between the support strand 31 and the container 11. For example, the prefabricated fastener 12 may include a prefabricated suspension cable ring. The prefabricated suspension cable ring supports the tension of the support strand 31 and applies prestress to it, thereby ensuring that the support strand 31 remains horizontal or at an appropriate angle between two opposing containers 11 in the same container group 1, maintaining the geometric stability of the photovoltaic support structure 3. Multiple prefabricated fasteners 12 are spaced apart along the second direction Y on the container 11 to support the uniform distribution of each support strand 31. This allows the two ends of each support strand 31 arranged sequentially along the second direction Y to be fixed to two opposing containers 11 in the same container group 1 via the prefabricated fastener 12, ensuring the structural stability of the flexible photovoltaic power station.

[0057] Optional, continue to refer to Figure 3 and Figure 4 The flexible photovoltaic power station also includes multiple cable clips 5, which are respectively set with multiple U-shaped fasteners 41; the cable clips 5 are located between the photovoltaic panel 21 and the support strand 31; the two ends of the U-shaped fasteners 41 pass through the cable clips 5 and a set of pre-made holes 213 in sequence.

[0058] Specifically, the cable clamps 5 are spaced apart along the first direction X on the support strands 31, and the cable clamps 5 can fix the support strands 31 through a clamping mechanism. It can be understood that the cable clamps 5 can serve as a connection interface between the support strands 31 and the photovoltaic panel 21, fixing the position of the support strands 31 to prevent slippage or displacement, thereby ensuring the firmness of the connection between the photovoltaic panel 21 and the support strands 31.

[0059] The cable clamp 5 is correspondingly positioned between the photovoltaic panel 21 and the support strand 31, allowing the support strand 31 to be secured between the U-shaped end of the U-shaped fastener 41 and the cable clamp 5. Both ends of the U-shaped fastener 41 can sequentially pass through the cable clamp 5 and a set of pre-drilled holes 213 and be threaded into a nut. As an intermediary component between the U-shaped fastener 41, the support strand 31, and the photovoltaic panel 21, the cable clamp 5 provides a stable fixing platform for the support strand 31 to be secured between the U-shaped fastener 41 and the cable clamp 5, and for both ends of the U-shaped fastener 41 to pass through the pre-drilled holes 213 corresponding to the cable clamp 5. This ensures that the support strand 31 and the photovoltaic panel 21 can be securely fixed by the U-shaped fastener 41. Meanwhile, under dynamic environments such as wind load and vibration, the clamping force and anti-detachment design of the steel cable clamp 5 can effectively prevent the photovoltaic panel 21 from loosening or falling off, enhance the connection strength between the photovoltaic panel 21 and the support strand 31, and improve the durability and safety of the flexible photovoltaic power station.

[0060] Optional, Figure 5This is a schematic diagram of another photovoltaic panel structure provided in an embodiment of the present invention, as shown below. Figure 5 As shown, the photovoltaic frame 212 includes a photovoltaic upper frame 2121 and a photovoltaic lower frame 2122; the photovoltaic upper frame 2121 is located on the side of the photovoltaic panel 211 away from the support strand 31; the photovoltaic lower frame 2122 is located on the side of the photovoltaic panel 211 close to the support strand 31; the photovoltaic upper frame 2121 includes a first pre-formed hole group 2131; the photovoltaic lower frame 2122 includes a second pre-formed hole group 2132; the first pre-formed hole group 2131 and the second pre-formed hole group 2132 overlap each other in a direction perpendicular to the photovoltaic panel 211; the two ends of the U-shaped fastener 41 pass through the second pre-formed hole group 2132 and the first pre-formed hole group 2131 of the same photovoltaic panel 21 in sequence.

[0061] Specifically, in the photovoltaic panel 21, the photovoltaic frame 212 can be set around the photovoltaic panel 211 to form a complete frame structure, thereby providing comprehensive structural support for the photovoltaic panel 211. The photovoltaic frame 212 includes a photovoltaic upper frame 2121 located on the side of the photovoltaic panel 211 away from the support strand 31 and a photovoltaic lower frame 2122 located on the side of the photovoltaic panel 211 closer to the support strand 31. The photovoltaic upper frame 2121 and photovoltaic lower frame 2122 together enhance the rigidity of the photovoltaic panel 211, preventing the photovoltaic panel 211 from deforming due to tension or external force in the suspension structure, while ensuring that the mechanical stress of the U-shaped fastener 41 is mainly borne by the photovoltaic frame 212, protecting the photovoltaic panel 211 from direct tension or strain.

[0062] Meanwhile, the photovoltaic upper frame 2121 includes a first pre-formed hole group 2131, and the photovoltaic lower frame 2122 includes a second pre-formed hole group 2132. The first pre-formed hole group 2131 and the second pre-formed hole group 2132 overlap each other in a direction perpendicular to the photovoltaic panel 211, so that the support strand 31 can be secured in the U-shaped fastener 41. The two ends of the U-shaped fastener 41 can sequentially pass through the steel cable clip 5 corresponding to the first pre-formed hole group 2131 and the second pre-formed hole group 2132, the two pre-formed holes 214 in the second pre-formed hole group 2132, and the two pre-formed holes 214 in the first pre-formed hole group 2131, and are threadedly connected to the nut. The photovoltaic upper frame 2121, the photovoltaic lower frame 2122, and the U-shaped fastener 41 form a double-layer fixing structure between the photovoltaic panel 21 and the support strand 31, which enhances the fixing stability of the photovoltaic panel 21 and the support strand 31, thereby improving the photovoltaic power generation performance of the flexible photovoltaic power station.

[0063] Optional, Figure 6 This is a schematic diagram of the structure of a photovoltaic panel provided in an embodiment of this utility model, as shown below. Figure 6As shown, the photovoltaic panel 211 includes a first protective layer 2111, a second protective layer 2112, and a photovoltaic electrode layer 2113 located between the first protective layer 2111 and the second protective layer 2112.

[0064] Specifically, the first protective layer 2111 is located on the side of the photovoltaic electrode layer 2113 facing away from the container 11. The first protective layer 2111 may include a weather-resistant layer 2114 and a buffer layer 2115. The weather-resistant layer 2114 is located on the outermost layer of the photovoltaic panel 211 to protect the photovoltaic electrode layer 2113 from corrosion by external environmental factors. For example, the material of the weather-resistant layer 2114 may include one or more of polyvinylidene fluoride (PVDF), ethylene tetrafluoroethylene (ETFE), ethylene trifluoroethylene chloride (ECTFE), or fluorinated ethylene propylene (FEP). The buffer layer 2115 is located on the side of the weather-resistant layer 2114 close to the photovoltaic electrode layer 2113 to absorb external impacts or vibrations, thereby protecting the photovoltaic electrode layer 2113 from external damage and ensuring the power generation performance and safety of the flexible photovoltaic power station. For example, the material of the buffer layer 2115 may include a glass fiber composite material.

[0065] A photovoltaic electrode layer 2113 is located between a first protective layer 2111 and a second protective layer 2112, and is used to convert incident sunlight into electrical energy to achieve the photovoltaic power generation performance of a flexible photovoltaic power station. For example, the material of the photovoltaic electrode layer 2113 may include monocrystalline silicon. The second protective layer 2112 is located on the side of the photovoltaic electrode layer 2113 closest to the container 11, and is used to protect the back side of the photovoltaic electrode layer 2113 from mechanical damage or environmental corrosion, further enhancing the rigidity and compressive strength of the photovoltaic panel 211, and preventing the photovoltaic panel 211 from deforming in the suspension structure due to tension or external forces, such as wind loads. For example, the material of the second protective layer 2112 may include a reinforced composite material.

[0066] The weather-resistant layer 2114, buffer layer 2115, photovoltaic electrode layer 2113, and second protective layer 2112 can all be bonded together with POE adhesive film, thus forming a high-strength, lightweight composite structure. This high-strength, lightweight composite structure makes the photovoltaic panel 211 lighter, reducing the pressure on the supporting stranded wires 31. Furthermore, the high-strength, lightweight composite structure ensures the photovoltaic power generation performance of the photovoltaic panel 211 while improving its rigidity and compressive strength, thereby enhancing the structural stability and photovoltaic power generation performance of the flexible photovoltaic power station.

[0067] Optional, continue to refer to Figure 4 The flexible photovoltaic power station also includes a container support component 13, which contacts the container 11; the container support component 13 is used to provide support force to the container 11; the direction of the support force is opposite to the tension direction of the support strand 31.

[0068] Specifically, the container support component 13 contacts the container 11 to provide support force to the container 11. Optionally, the container support component 13 includes multiple container support rods 131. The container support rods 131 can be positioned on the side of the container 11 facing the support strand 31, and the container support rods 131 can extend obliquely towards the bottom of the container 11, thereby forming a triangular support structure. This allows the container support rods 131 to provide support force to the container 11, and the direction of the support force is opposite to the tension direction of the support strand 31. The container support rods 131 can disperse the tension exerted by the support strand 31 on the container 11 and the weight of the photovoltaic panel 21, enhancing the structural stability of the container 11 and preventing the container 11 from tilting or deforming due to the tension of the support strand 31 or external forces such as wind loads. This enables reliable operation of the flexible photovoltaic power station under large span and complex climatic conditions, improving the structural stability of the flexible photovoltaic power station.

[0069] Optionally, the container support rod 131 is rotatably connected to the side of the container 11.

[0070] Specifically, the container support rod 131 is rotatably connected to the side of the container 11, meaning the container support rod 131 can adopt a foldable structure. During transportation, the container support rod 131 can be folded and fixed to the side wall of the container 11 facing the support strand 31 to avoid occupying extra space. This ensures that the container 11 can serve as transport packaging, integrating all the components of the flexible photovoltaic power station, facilitating the overall transportation of the flexible photovoltaic power station to the installation site. In addition, the foldable design of the container support rod 131 allows it to be quickly unfolded and fixed inside the container 11 after transportation to the installation site, without the need for additional on-site processing or assembly. This simplifies the installation process, reduces construction time and labor costs, and improves the flexibility of the flexible photovoltaic power station, enabling it to adapt to temporary or flexible application scenarios in densely populated areas such as parks and squares.

[0071] Optional, continue to refer to Figure 4 The flexible photovoltaic power station also includes an energy storage system 14, which is integrated inside the container 11 and electrically connected to the photovoltaic panel 21.

[0072] Specifically, the energy storage system 14 is electrically connected to the photovoltaic panel 21 to store the electrical energy generated by the photovoltaic panel 21. The energy storage system 14 is integrated inside the container 11 to make full use of the space inside the container 11. Furthermore, the electrical energy stored in the energy storage system 14 can be released at night or when there is no sunlight, thus enabling the flexible photovoltaic power station to operate in a mode of generating photovoltaic power during the day and supplying electricity at night, improving energy efficiency. The flexible photovoltaic power station can provide lighting at night and also provide power to other electrical facilities, such as charging piles, making it suitable as a temporary or flexible base station in densely populated areas such as parks and squares, thus enhancing the flexibility of its use.

[0073] Optional, continue to refer to Figure 4 The distance L1 between two opposing containers 11 in the same container group 1 can be between 15m and 30m to allow the support strands 31 to form a longer suspension distance, thereby enabling them to support more photovoltaic panels 21 and maximizing the photovoltaic power generation area of ​​the flexible photovoltaic power station while maintaining available ground space. Understandably, if L1 is too large, i.e., the span of the support strands 31 is too long, it will cause the support strands 31 to sag more, increasing the tension exerted by the support strands 31 on the container 11, which may exceed the maximum load-bearing capacity of the container 11, leading to deformation or failure of the flexible photovoltaic power station structure. If L1 is too small, i.e., the span of the support strands 31 is too small, it will limit the number of photovoltaic panels 21 that the support strands 31 can support, thereby reducing the coverage area of ​​the photovoltaic array and lowering the photovoltaic power generation performance of the flexible photovoltaic power station. Therefore, by setting the distance L1 between two opposing containers 11 in the same container group 1 to be between 15m and 30m, the photovoltaic power generation performance of the flexible photovoltaic power station can be maximized while ensuring the stability of the flexible photovoltaic power station structure.

[0074] Optional, continue to refer to Figure 4 The length L2 of container 11 along the second direction Y can be between 5m and 10m to ensure that container 11 has sufficient bottom area to withstand the tension of the support strands 31 and the weight of the photovoltaic panels 21. This prevents container 11 from tilting or shifting due to the tension of the support strands 31 or wind load, thus enhancing the structural stability of the flexible photovoltaic power station. It is understandable that if L2 is too large, i.e., the size of container 11 is too large, it will increase the transportation difficulty and cost of the flexible photovoltaic power station; if L2 is too small, i.e., the size of container 11 is too small, the container 11 will not be able to withstand the tension of the large-span support strands 31 or wind load, leading to tilting or shifting of container 11. Therefore, by setting the length L2 of container 11 along the second direction Y to between 5m and 10m, the structural stability of the flexible photovoltaic power station can be ensured while improving its operational flexibility.
