Summary of the Invention

Problems to be Solved by the Invention

[0004] When manufacturing a floating solar cell structure as described above, wiring is installed on the panel structure in a state where the panel structure is placed flat on the ground. However, in this case, dust easily accumulates on the panel structure, and it is necessary for an operator to remove the dust. Further, when performing wiring installation work on the panel structure placed flat on the ground, the operator has to bend down or assume a semi-crouching posture, which increases the burden on the operator. In particular, at the water's edge such as a pool, it is often difficult to secure a sufficient working area, and the work of installing a large number of large-sized solar cells further increases the burden on the operator.

MODE FOR CARRYING OUT THE INVENTION

[0011] The following describes embodiments of the mounting frame, the manufacturing method of the floating solar cell structure, and the installation method of the floating solar cell structure according to the present invention, based on the drawings. However, the present invention is not limited to these embodiments. Furthermore, in the following embodiments, if there are multiple configuration examples, the elements of each configuration example can be combined as appropriate. Also, the components in the following embodiments include those that are easily substituted or substantially identical to those that are easily substituted by those skilled in the art.

[0012] Figure 1 shows an example of a mounting frame 100 according to this embodiment. As shown in Figure 1, the mounting frame 100 according to this embodiment is used in the manufacturing process of a floating solar cell structure 1. The floating solar cell structure 1 is manufactured by installing wiring 6 on a panel structure 4 in which a solar cell panel 2 is supported by a buoyancy body 3. The solar cell panel 2 is formed to be flexible. The buoyancy body 3 is formed using, for example, a resin material. The buoyancy body 3 may be formed to be flexible. The buoyancy body 3 can be in the shape of, for example, a plate or a bag. The buoyancy body 3 is formed to float on water together with the solar cell panel 2 and wiring 6 while supporting the solar cell panel 2.

[0013] The mounting frame 100 is used to support at least one of the target structures 5 of the panel structure 4 and the floating solar cell structure 1. The mounting frame 100 comprises a base portion 10 and a support portion 20.

[0014] The base portion 10 is placed on the worker surface F on which the worker moves. The base portion 10 has a first plate-like member 11. The first plate-like member 11 is rectangular in shape. The first plate-like member 11 is formed using a rigid material such as resin or wood. A connecting member 12 is provided on the first plate-like member 11. The connecting member 12 is deformable so that a part of the first plate-like member 11 is raised relative to the first plate-like member 11. In addition, a block-like member with a greater vertical thickness than the first plate-like member 11 may be used in the base portion 10. Furthermore, in the base portion 10, the height position of the support surface 22, which will be described later, can be adjusted by adjusting the vertical thickness using the first plate-like member 11, the block-like member, etc.

[0015] The support portion 20 has a second plate-shaped member 21. The second plate-shaped member 21 is rectangular in shape and is made of a rigid material such as resin or wood, and two of them are provided. The two second plate-shaped members 21 are detachably attached to the first plate-shaped member 11. The two second plate-shaped members 21 are each attached to the first plate-shaped member 11 via a connecting member 12.

[0016] The second plate-shaped member 21 has a support surface 22. The support surface 22 is positioned at least partially higher than the worker surface F when the base portion 10 is placed on the worker surface F. The support surface 22 supports the target structure 5. The support surface 22 is, for example, planar and is positioned at an angle to the worker surface F. The angle formed by the two second plate-shaped members 21 can be, for example, 70° or more and 80° or less. However, the angle formed by the two second plate-shaped members 21 is not limited to the above range and may be less than 70° or greater than 80°.

[0017] The above-described mounting frame 100 can be easily manufactured by assembling it using three plate-shaped members: one first plate-shaped member 11 and two second plate-shaped members 21. Therefore, the mounting frame 100 can be installed around the water surface where the floating solar cell structure 1 will be placed, for example, by assembling it around the water surface. In this case, the floating solar cell structure 1 can be manufactured around the water surface and the manufactured floating solar cell structure 1 can be placed on the water surface. Note that two or more first plate-shaped members 11 may be provided. Also, one second plate-shaped member 21 may be provided, or three or more may be provided. Furthermore, the first plate-shaped member 11 and the second plate-shaped members 21 are not limited to being made of a rigid material, and may be formed in the shape of a bag and inflated by filling the inside with gas. In this case, the first plate-shaped member 11 and the second plate-shaped members 21 may be formed in the shape of a bag so that they become one unit.

[0018] Figures 2A and 2B show other examples of the frame according to this embodiment. In the frame 100A shown in Figure 2A, the second plate-shaped member 21A of the support portion 20A is provided with an opening 23 that penetrates both sides in a part of the support surface 22. The opening 23 is formed in such a way that it leaves a portion capable of supporting the target structure 5. In the example shown in Figure 2A, the opening 23 is formed in a rectangular shape so that it can support the outer edge of the target structure 5.

[0019] The presence of the opening 23 reduces the weight of the second plate-like member 21A compared to a configuration without the opening 23. Furthermore, in the configuration with the opening 23, the target structure 5 can be accessed from the back side of the support surface 22 via the opening 23. Therefore, work can be performed from both the front and back sides of the target structure 5.

[0020] Furthermore, as shown in Figure 2B, the second plate-shaped member 21A may be provided with a restraining portion 24 to suppress displacement of the target structure 5 supported on the support surface 22. The restraining portion 24 has a receiving member 24a and an anti-slip processed portion 24b. The receiving member 24a receives the lower end of the target structure 5 when it is supported on the support surface 22. The anti-slip processed portion 24b is provided on the support surface 22 and suppresses slippage of the target structure 5.

[0021] Furthermore, as shown in Figure 2B, a membrane portion 25 may be provided to cover the opening 23. In this configuration, the membrane portion 25 covers the opening 23, making it possible to block gusts of wind from the back side of the support surface 22. This prevents gusts of wind from passing through the opening 23 and blowing onto the target structure 5. Although Figure 2B shows a configuration in which the membrane portion 25 is arranged on the back side of the second plate-shaped member 21, the configuration is not limited to this, and it may also be arranged on the front side of the second plate-shaped member 21.

[0022] Furthermore, as shown in Figure 2B, the second plate-shaped member 21A may be provided with impact-absorbing portions 26 at its corners. The impact-absorbing portions 26 may be configured with, for example, cushioning material such as sponge or rubber, or the corners may be deformable, such as denting or crushing in response to impact. In configurations where the corners are deformable, the corners may be formed to be elastically deformable.

[0023] Figures 3A and 3B show other examples of the frame according to this embodiment. In the frame 100B shown in Figures 3A and 3B, the support portion 20B is deformable so that the support surface 22 can switch between a state inclined with respect to the worker surface F and a state parallel to the worker surface F. In this embodiment, the upper and lower portions of the second plate-shaped member 21B are connected via a hinge portion 27, and the upper portion is rotatably provided by the hinge portion 27.

[0024] Figure 3A shows the configuration of the second plate-shaped member 21B in a state where the support surface 22 is inclined with respect to the worker surface F. Figure 3B shows the configuration in which the second plate-shaped member 21B has deformed so that the support surface 22 is parallel to the worker surface F. By deforming the second plate-shaped member 21B in this way, the target structure 5 can be placed on the support surface 22 which is parallel to the worker surface F at a position higher than the worker surface F, and work can be performed. In this case, as shown in Figure 3B, it is possible to accommodate cases where the dimensions of the target structure 5 are large or long.

[0025] Figures 4A to 4C show other examples of the frame according to this embodiment. The frame 100C shown in Figure 4A does not have a base, the support part 20C is triangular prism-shaped, and one of the sides of the support part 20C is a support surface 22. The support part 20C may be hollow. The support surface 22 is positioned at an angle with respect to the worker surface F. By supporting the target structure 5 on the support surface 22 which is at an angle with respect to the worker surface F in this way, it is possible to suppress the accumulation of foreign matter such as dirt on the upper surface of the target structure 5, and the work efficiency when a worker works on the target structure 5 can be improved.

[0026] Furthermore, the frame 100D shown in Figure 4B has a base portion 10D provided at the bottom of the frame 100C shown in Figure 4A. The base portion 10D is rectangular in shape. The base portion 10D may also be hollow. With this configuration, the height of the support surface 22 can be made higher with respect to the worker surface F, thereby improving the work efficiency when the worker is working on the target structure 5.

[0027] Furthermore, in the mounting frame 100E shown in Figure 4C, the support surface 22 of the support portion 20E is formed in an upwardly convex curve. In this configuration, the floating solar cell structure 1 can be supported on the upwardly curved support surface 22. For the portion of the support portion 20E that constitutes the support surface 22, for example, a semi-cylindrical member or a plate-shaped member having an upwardly curved surface can be used. If a plate-shaped member is used, an opening may be provided in part of it.

[0028] Next, a method for manufacturing a floating solar cell structure according to this embodiment will be described. Figure 5 is a flowchart showing an example of a method for manufacturing a floating solar cell structure according to this embodiment. As shown in Figure 5, the method for manufacturing a floating solar cell structure includes a support surface preparation step S10, a support step S20, and a work step S30.

[0029] Figure 6 is a schematic diagram showing an example of the support surface preparation process S10. As shown in Figure 6, in the support surface preparation process S10, the support surface 22 is set by installing one of the frames 100, 100A, 100B, 100C, 100D, or 100E described above. The following explanation will use the case where frame 100 is installed as an example. The support surface 22 is positioned at least partially higher than the worker surface F on which the worker moves.

[0030] Figure 7 is a schematic diagram showing an example of the support process S20. As shown in Figure 7, in the support process S20, the panel structure 4 is supported on the support surface 22. In this embodiment, an example is shown in which the panel structure 4 is arranged in two rows vertically and four columns horizontally, but the arrangement of the panel structure 4 is not limited to this case. When the panel structure 4 is arranged in two rows vertically, the panel structure 4 is arranged so that the connectors C of each solar cell panel 2 face each other, that is, the connector C of the solar cell panel 2 placed on the upper side is located at the bottom, and the connector C of the solar cell panel 2 placed on the lower side is located at the top. With this arrangement, when forming the wiring in the work process S30 described later, the work can be performed all at once at the central height position in the vertical direction. Alternatively, the panel structure 4 may be arranged so that the connector C of the solar cell panel 2 placed on the upper side is located at the top. Alternatively, the panel structure 4 may be arranged so that the connector C of the solar cell panel 2 placed on the lower side is located at the bottom. In these cases, when forming the wiring in the work process S30, the wiring can be formed at the upper or lower end in the vertical direction, depending on the position of the connector C. Furthermore, in the support process S20, if the panel structure 4 is flexible, the panel structure 4 can be supported on a support surface 22 with dimensions that are capable of supporting the entire panel structure 4. By supporting the entire panel structure 4 on the support surface 22, deflection of the panel structure 4 can be suppressed. Also, in the support process S20, if the panel structure 4 is not flexible, the panel structure 4 can be supported on a support surface 22 with dimensions that are capable of supporting only a part of the panel structure 4. In this case, the area of ​​the support surface 22 can be kept to the minimum necessary, thus enabling miniaturization of the frames 100, 100A, 100B, 100C, 100D, and 100E.

[0031] Figure 8 is a schematic diagram showing an example of work process S30. As shown in Figure 8, in work process S30, with the panel structure 4 supported on the support surface 22, predetermined work is performed, including the work of installing wiring 6 on the panel structure 4, to form the floating solar cell structure 1. If an opening 23 is provided in the support surface 22, the worker can access the panel structure 4 from the back side through the opening 23 and perform the work.

[0032] When installing wiring 6 to the panel structure 4, the wiring 6 can be placed surrounded by a bag member 8, such as a balloon formed in a rod shape along the wiring 6. Specifically, the bag member 8, with the air removed, is placed around the wiring 6, the wiring 6 is electrically connected to the solar panel 2, and then air is added to the bag member 8. When removing the floating solar cell structure 1, the bag member 8 may be recovered together with the wiring 6 with the air removed, or the bag member 8 may be separated from the wiring 6 and only the wiring 6 may be recovered. Note that the bag member 8 is not required.

[0033] Figures 9 and 10 show enlarged views of the connection portion A between connector C and wiring 6. As shown in connection portion A1 in Figure 9, the wiring 6 may be placed in the gap inside multiple bag members 8 joined together on their sides. Alternatively, as shown in connection portion A2 in Figure 10, the wiring 6 may be placed inside a single bag member 8.

[0034] Figure 11 is a schematic diagram illustrating an example of work process S30. In work process S30, as shown in Figure 11, a connected structure 7 is formed by connecting multiple panel structures 4 together. For connecting the multiple panel structures 4, a mooring member 9 such as a wire can be used. The example shown in Figure 11 illustrates the case where floating solar cell structures 1 arranged horizontally are connected.

[0035] Figures 12 to 16 schematically show an example of the process after the formation of the connecting structure 7 in work process S30. As shown in Figure 12, after the formation of the connecting structure 7, at least one of the floating solar cell structures 1 of the connecting structure 7 is folded so that it overlaps with the adjacent floating solar cell structure 1, thereby creating an empty space S1 on the support surface 22.

[0036] As shown in Figure 13, the folded connecting structure 7 is moved along the support surface 22 so that an empty space S1 is positioned next to the floating solar cell structure 1 located at one end of the folded connecting structure 7.

[0037] As shown in Figure 14, after the folded connecting structure 7 is moved, a new panel structure 4 (4A) is placed in the empty space S1.

[0038] As shown in Figure 15, wiring 6 is installed on the new panel structure 4A to form a new floating solar cell structure 1 (1A).

[0039] As shown in Figure 16, a new floating solar cell structure 1A is connected to the floating solar cell structure 1 at one end of the folded connecting structure 7 to form a new connecting structure 7 (7A).

[0040] This makes it possible to form a connected structure 7 by linking a number of floating solar cell structures 1 that exceeds the number of target structures 5 that can be placed on the support surface 22. In this embodiment, the method for manufacturing a floating solar cell structure has been described in which the panel structure 4 and the floating solar cell structure 1 are supported on the support surface 22 of the mounting frames 100, 100A, 100B, 100C, 100D, and 100E, but is not limited to this embodiment. For example, the floating solar cell structure 1 may be supported using a surface different from the support surface 22 of the mounting frames 100, 100A, 100B, 100C, 100D, and 100E as the support surface, as long as it is positioned higher than the worker surface F on which the worker moves. In cases where an existing surface different from the support surface 22 of the mounting frames 100, 100A, 100B, 100C, 100D, and 100E is used, the support surface preparation step S10 can be omitted.

[0041] Next, an example of a method for installing a floating solar cell structure according to this embodiment will be described. Figure 17 is a flowchart showing an example of a method for installing a floating solar cell structure according to this embodiment. Figures 18 to 26 are schematic diagrams showing each step of the installation method for a floating solar cell structure in this embodiment.

[0042] As shown in Figure 17, the installation method for the floating solar cell structure according to this embodiment includes a support surface preparation step S110, a support step S120, a work step S130, a first moving step S140, a panel placement step S150, a wiring connection step S160, a second moving step S170, a determination step S180, and an installation step S190.

[0043] Figure 18 is a schematic diagram showing an example of the support surface preparation step S110. As shown in Figure 18, in the support surface preparation step S110, a support surface 22 is formed on which multiple panel structures 4 and floating solar cell structures 1 can be arranged in a line in one direction. Here, the case in which a support surface 22 parallel to the horizontal plane is formed by forming a table-shaped frame 200 on the worker surface F is used as an example. Alternatively, the support surface 22 along the horizontal plane may be formed using the frame 100B described above instead of the frame 200. In addition, in the support surface preparation step S110, a slope 40 is installed around the water surface W on which the floating solar cell structures 1 will be installed, extending from the end of the support surface 22 toward the water surface W. The slope 40 is positioned to slope downward from the support surface 22 toward the water surface W. The slope 40 is, for example, planar. In the installation method of the floating solar cell structure according to this embodiment, one direction is the direction from the support surface 22 toward the slope 40.

[0044] Figure 19 is a schematic diagram illustrating an example of the support process S120. As shown in Figure 19, in the support process S120, multiple panel structures 4 are arranged in a unidirectional pattern on the support surface 22. Although Figure 19 shows an example where two panel structures 4 are arranged on the support surface 22, the number of panel structures 4 is not limited to two; there may be three or more.

[0045] Figure 20 is a schematic diagram showing an example of work process S130. As shown in Figure 20, in work process S130, wiring 6 is installed on two panel structures 4 placed on the support surface 22, and multiple panel structures 4 are connected to each other to form a connected structure 7 in which two floating solar cell structures 1 are connected. The wiring 6 can be placed in the portion enclosed by the bag member 8 or inside the bag member 8, as described above. Alternatively, a structure that allows the wiring 6 to float above the water surface, such as a float (buoy), may be used instead of the bag member 8. Furthermore, when three or more floating solar cell structures 1 are placed on the support surface 22, at least the floating solar cell structure 1 on the slope 40 side in one direction is connected to the floating solar cell structure 1 adjacent to that floating solar cell structure 1.

[0046] Figure 21 is a schematic diagram illustrating an example of the first moving process S140. As shown in Figure 21, in the first moving process S140, the connecting structure 7 is slid so that the floating solar cell structure 1 on the slope side in one direction moves from the support surface 22 to the slope 40. This movement of the connecting structure 7 causes the floating solar cell structure 1 that was positioned on the opposite side of the slope 40 to move towards the slope 40. As a result, an empty space S2 is formed on the support surface 22 where one panel structure 4 can be placed.

[0047] Figure 22 is a schematic diagram showing an example of the panel placement process S150. As shown in Figure 22, in the panel placement process S150, a new panel structure 4 (4B) is placed in the empty space S2 formed on the support surface 22 by the movement of the connecting structure 7.

[0048] Figure 23 is a schematic diagram showing an example of the wiring connection process S160. As shown in Figure 23, in the wiring connection process S160, wiring 6 is installed on the new panel structure 4B to form a new floating solar cell structure 1B. The new floating solar cell structure 1B is then connected to a floating solar cell structure 1 adjacent to the new floating solar cell structure 1B in one direction among the connecting structures 7 to form a new connecting structure 7 (7B).

[0049] Figure 24 is a schematic diagram showing an example of the second moving process S170. As shown in Figure 24, in the second moving process S170, the new connecting structure 7B is slid so that the floating solar cell structure 1(1B) on the slope side in one direction of the portion of the new connecting structure 7B that is supported by the support surface 22 is positioned from the support surface 22 to the slope 40.

[0050] In the determination step S180, it is determined whether the number of floating solar cell structures 1 connected in the new connecting structure 7B has reached a predetermined value. If the determination step S180 determines that the number of floating solar cell structures 1 connected in the new connecting structure 7B has not reached a predetermined value (No. in step S180), the process returns to step S150, and the panel placement step S150, wiring connection step S160, and second movement step S170 are repeated. Alternatively, the determination step S180 may be performed before the second movement step S170, and if it is determined that the number of floating solar cell structures 1 connected in the new connecting structure 7B has not reached a predetermined value, the second movement step S170 may be performed, and then the process returns to step S150 to perform the panel placement step S150 and wiring connection step S160. In this way, the panel placement step S150, wiring connection step S160, and second movement step S170 are repeated until the number of floating solar cell structures 1 reaches a predetermined value. Figure 25 schematically shows an example of the connection state of the connecting structure 7 in the determination step S180. Through the repeated process described above, as shown in Figure 25, the number of connected floating solar cell structures 1 in the connecting structure 7 (7C) increases, and the floating solar cell structures 1 move from the slope 40 onto the water surface W in the order in which the wiring connection step S160 was performed.

[0051] If, in the determination step S180, it is determined that the number of floating solar cell structures 1 connected to the new connecting structure 7C has reached a predetermined value (Yes in step S180), the installation step S190 is performed. Figure 26 is a schematic diagram showing an example of the installation step S190. As shown in Figure 26, in the installation step S190, the new connecting structure 7C is installed on the water surface W via the slope 40. When moving the connecting structure 7C on the water surface W, it can be pulled, for example, from the water surface W side (the opposite bank side of the support surface 22 across the water surface W) using an auxiliary rope 50 or the like.

[0052] As described above, the mounting frames (100, 100A, 100B, 100C, 100D, 100E) according to this embodiment are mounting frames that support at least one of the target structures 5 of a panel structure 4 in which a solar cell panel 2 is supported by a buoyancy body 3, and a floating solar cell structure 1 in which wiring 6 is arranged on the panel structure 4, and comprise a base portion 10 that is placed on a worker surface F in which an operator moves, and a support portion 20 having a support surface 22 that is positioned at least a portion higher than the worker surface F when the base portion 10 is placed on the worker surface F, and supports the target structure 5.

[0053] This configuration allows workers to perform tasks while the target structure 5 is supported on a support surface 22 located at a higher position than the worker's surface F. This reduces the workload on workers during the manufacturing process of floating solar cell structures.

[0054] In the frame according to this embodiment, the support surface 22 is planar and is positioned at an angle with respect to the worker surface F.

[0055] With this configuration, the support surface 22 is planar and positioned at an angle to the worker surface F, so that the worker can perform work with the target structure 5 tilted relative to the worker surface F.

[0056] In the frame according to this embodiment, the support portion 20 has a suppression portion 24 that suppresses displacement of the target structure 5 supported on the support surface 22.

[0057] With this configuration, the suppression unit 24 is provided, allowing the worker to perform their duties while suppressing the displacement of the target structure 5.

[0058] In the frame according to this embodiment, the restraining portion 24 has a receiving member 24a that receives the lower end of the target structure 5 when it is supported on the support surface 22.

[0059] With this configuration, the worker can perform work with the target structure 5 positioned so that the lower end is supported by the receiving member 24a.

[0060] In the frame according to this embodiment, the restraining portion 24 has an anti-slip processed portion 24b provided on the support surface 22.

[0061] This configuration allows for the suppression of slippage of the target structure 5 when an operator performs work on the target structure 5.

[0062] In the frame according to this embodiment, the base portion 10 has a first plate-shaped member 11 that is placed on the worker surface F, and the support portion 20 has a support surface 22 and a second plate-shaped member 21 that is detachably attached to the first plate-shaped member 11.

[0063] With this configuration, the frame can be installed and removed by attaching and detaching the first plate-shaped member 11 and the second plate-shaped member 21. This makes it easy to install and remove the frame.

[0064] In the frame according to this embodiment, the second plate-shaped member 21 is formed to have an opening 23 that penetrates both the front and back surfaces in a part of the support surface 22.

[0065] With this configuration, the second plate-shaped member 21 can be made lighter by providing an opening 23 in the second plate-shaped member 21. In addition, an operator can access the target structure 5 from the back side of the support surface 22 through the opening 23.

[0066] In the frame according to this embodiment, the second plate-shaped member 21 has a membrane portion 25 that covers the opening 23.

[0067] With this configuration, the membrane portion 25 is provided, which reduces the weight of the second plate-like member 21 while suppressing gusts of wind from blowing through the opening 23.

[0068] In the frame according to this embodiment, the second plate-shaped member 21 is deformable so that the support surface 22 can switch between a state in which it is inclined with respect to the worker surface F and a state in which it is parallel to the worker surface F.

[0069] With this configuration, by deforming the second plate-shaped member 21, the orientation of the target structure 5 can be switched and supported according to the work content, the configuration of the target structure 5, etc.

[0070] In the frame according to this embodiment, the second plate-shaped member 21 is provided with an impact-absorbing portion 26 at its corner.

[0071] With this configuration, since impact mitigation portions 26 are provided at the corners of the second plate-shaped member 21, it is possible to suppress the target structure 5 from being subjected to impact by the corners of the second plate-shaped member 21.

[0072] In the frame according to this embodiment, the support surface 22 is a curved surface that is convex upward.

[0073] This configuration allows the target structure 5 to be supported in a curved state, such that it is convex upwards.

[0074] The manufacturing method of the floating solar cell structure according to this embodiment includes a support step S20 in which a panel structure 4, in which a solar cell panel 2 is supported by a buoyancy body 3, is supported on a support surface 22 which is positioned at least a portion higher than the worker surface F on which the worker moves, and a work step S30 in which predetermined work, including the work of installing wiring 6 to the panel structure 4, is performed to form the floating solar cell structure 1 while the panel structure 4 is supported on the support surface 22.

[0075] With this configuration, the panel structure 4 is supported on a support surface 22 located at a higher position than the worker surface F on which the worker moves, allowing the worker to perform predetermined tasks, including the installation of wiring 6, on the panel structure 4. This reduces the workload on the worker during the manufacturing process of the floating solar cell structure 1.

[0076] The method for manufacturing a floating solar cell structure according to this embodiment further includes a support surface preparation step S10 prior to the support step S20, in which a support surface 22 is prepared as a support surface 22 provided on the frame (100, 100A, 100B, 100C, 100D, 100E) described in claim 1.

[0077] With this configuration, by preparing a support surface 22 for the frame, the panel structure 4 can be easily supported on the support surface 22, which is positioned higher than the worker's surface F.

[0078] In the manufacturing method of a floating solar cell structure according to this embodiment, in the support step S20, if the panel structure 4 is flexible, the panel structure 4 is supported on a support surface 22 having dimensions that can support the entire panel structure 4.

[0079] With this configuration, the entire flexible panel structure 4 is supported on the support surface 22, thereby suppressing the deflection of the panel structure 4.

[0080] In the manufacturing method of the floating solar cell structure according to this embodiment, in the support step S20, if the panel structure 4 is not flexible, the panel structure 4 is supported on a support surface 22 having dimensions that can support a part of the panel structure 4.

[0081] With this configuration, work can be performed with a portion of the non-flexible panel structure 4 supported on the support surface 22, thereby reducing the area of ​​the support surface 22 and saving workspace.

[0082] In the manufacturing method of a floating solar cell structure according to this embodiment, the support surface 22 is capable of arranging a plurality of panel structures 4 and floating solar cell structures 1 side by side in one direction. In the support step S20, a plurality of panel structures 4 are arranged side by side on the support surface 22. In the work step S30, predetermined operations are performed, including installing wiring 6 on the plurality of panel structures 4 arranged on the support surface 22 and connecting the plurality of panel structures 4 to each other, thereby forming a connected structure 7 in which a plurality of floating solar cell structures 1 are connected.

[0085] This configuration allows for the efficient manufacture of a connected structure 7, in which multiple floating solar cell structures 1 are linked together, using the limited space of the support surface 22.

[0086] The method for arranging the floating solar cell structure according to this embodiment includes a support step S120 and a work step S130 corresponding to the manufacturing method of the floating solar cell structure described above. The support step S120 and work step S130 are performed with a slope installed around the water surface W on which the floating solar cell structure 1 is to be placed, with a slope extending from one end of the support surface 22 toward the water surface W. The work step S130 is performed by connecting at least the floating solar cell structure 1 on the slope side in one direction with the floating solar cell structure 1 adjacent to it to form a connecting structure 7. The support surface 22 can be used to arrange multiple panel structures 4 and floating solar cell structures 1 in a line in one direction. In the support step S120, multiple panel structures 4 are arranged in a line on the support surface 22 in one direction. In the work step S130, predetermined operations are performed, such as installing wiring 6 on the multiple panel structures 4 placed on the support surface 22 and connecting the multiple panel structures 4 to each other, thereby forming a connecting structure 7 in which multiple floating solar cell structures 1 are connected.
