Description

[Technical field]

[0001] The present invention relates to a power supply system for a temporary building. [Background technology]

[0002] In recent years, solar power generation technology has become widespread, and solar panels are now installed not only on a large scale in vacant lots in suburban areas, but also in large buildings and detached houses in urban areas.

[0003] When fixing solar panels to a roof surface, they are installed with a solid base made of angle steel or the like to prevent wind scattering from the roof surface. The base is fixed to the roof surface with bolts, for example, by drilling bolt holes in the roof surface. The area around the bolt holes is waterproofed. In this case, the roof surface needs to be inspected periodically, considering that the repeated stress caused by the wind force on the panels on the roof surface can cause damage to the waterproofing. This creates the problem of the need for safety equipment such as walkways around the panels and handrails to prevent them from falling off the roof surface.

[0004] Therefore, solar panels in buildings are sometimes installed not only on the roof top surface but also on the wall surface. Patent Document 1 is disclosed as a prior art related to a mounting structure for solar panels to be installed on the wall surface of a house. Patent Document 1 describes a structure for solar panels to be installed on the balcony of a house, which allows the position to be adjusted according to the sunlight, weather, etc. By installing solar panels on the wall surface, the above-mentioned problems that arise when installing them on the roof surface can be solved. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent Publication No. 2021-165485 Summary of the Invention [Problem to be solved by the invention]

[0006] According to the technology disclosed in Patent Document 1, the effort required to install solar panels is significantly reduced compared to installing them on the roof surface, but there is a limit to the number that can be installed because a considerable load is exerted on the balcony.

[0007] In addition, temporary buildings are often used as offices at construction sites, etc. As temporary buildings are often removed after a few years, when introducing solar power generation to supply electricity to lighting equipment, etc., a power supply system that is easy to install and remove is desirable.

[0008] The present invention has been made in consideration of the above points, and has an object to provide a power supply system for a temporary building that is easy to set up and take down. [Means for solving the problem]

[0009] In order to achieve the above-mentioned object, the power supply system for a temporary building of the present invention comprises a solar panel, a support frame that supports the solar panel and aligns the solar panel with a wall surface of the temporary building when fixed to the temporary building, a storage battery that stores electricity generated by the solar panel and can supply the stored electricity to electrical equipment, and a distribution board provided between the storage battery and the electrical equipment, wherein the solar panel extends in a first direction and has a plurality of separate panels arranged in a second direction perpendicular to the first direction, the support frame has a vertical single pipe extending in the vertical direction and a horizontal single pipe extending in the horizontal direction and connected to the vertical single pipe, and is removably fixed to the temporary building, and the distribution board is connected to the storage battery and a second power source different from the storage battery, and selects the source of electricity to be supplied to the electrical equipment depending on the amount of electricity stored in the storage battery.

[0010] In the present invention, the support frame that supports the solar panel has a first single pipe and a second single pipe connected together and is removably fixed to a temporary building, making installation and removal easy. In addition, in the present invention, since the solar panel has a configuration including a plurality of separate panels, the solar panel can be carried by hand when being installed, improving workability. Furthermore, in the present invention, since the solar panels are supported along the walls of the temporary building, there is no need for the installation of a base, waterproofing, safety equipment, etc., which are required when solar panels are installed on the roof surface. Furthermore, in the present invention, the distribution board is connected to the storage battery and the second power source, and the source of electricity to be supplied to the electrical equipment is selected depending on the amount of electricity stored in the storage battery. Therefore, when the amount of electricity stored in the storage battery decreases at night, for example, electricity from the second power source can be supplied to the electrical equipment.

[0011] In addition, in the temporary building power supply system according to the present invention, the support frame may be configured to be supported from below by a jack member provided on a floor plate.

[0012] With this configuration, the load of the solar panel and the support frame can be transferred to the ground. Furthermore, with this configuration, continuous inspection of the solar panels after installation can be carried out from the ground, eliminating the risk of danger during daily maintenance and inspection.

[0013] In the temporary building power supply system according to the present invention, the separation panel may have a handle.

[0014] With this configuration, the device can be carried by hand by gripping the handle, improving workability.

[0015] In addition, in the temporary building power supply system according to the present invention, the separation panel may be configured so that the handle is fixed to either the vertical single pipe or the horizontal single pipe by a clamp member.

[0016] With this configuration, the separation panel can be easily fixed to the support frame.

[0017] In addition, in the temporary building power supply system of the present invention, the first direction may be a horizontal direction, the second direction may be a vertical direction, and the separation panel may be positioned at a position away from a window portion of the temporary building in the height direction.

[0018] With this configuration, the separation panel can be prevented from being positioned outside the window of the temporary building, thereby preventing the light entering the interior of the building from being obstructed.

[0019] In addition, in the temporary building power supply system according to the present invention, the storage battery may be configured to be placed inside the temporary building.

[0020] With this configuration, deterioration of the storage battery can be reduced and power can be supplied to the outside of the system.

[0021] In addition, in the temporary building power supply system according to the present invention, the second power source may be a commercial power source.

[0022] With this configuration, when the amount of stored electricity in the storage battery decreases during the night or the like, electric power from the commercial power source received from the power company can be supplied to the electric device.

[0023] Furthermore, in the temporary building power supply system according to the present invention, the distribution board may be configured to have a power transfer switch that switches the power supply source to the second power source depending on the amount of electricity stored in the storage battery.

[0024] This configuration allows for significant cost reduction compared to incorporating an expensive power conditioner in the distribution board. Effect of the Invention

[0025] The present invention makes it possible to provide a power supply system for a temporary building that is easy to set up and take down. [Brief description of the drawings]

[0027] Hereinafter, an embodiment of a power supply system for a temporary building according to the present invention will be described with reference to Figs. The following embodiment shows one aspect of the present invention, does not limit the present invention, and can be modified as desired within the scope of the technical idea of ​​the present invention. In addition, in the following drawings, the scale and number of each structure are different from the actual structure in order to make each configuration easier to understand.

[0028] Fig. 1 is a schematic diagram of a temporary building 100 in which a power supply system 1 is installed. Fig. 2 is a block diagram related to power supply by the power supply system 1. As shown in FIGS. 1 and 2, the power supply system 1 includes a solar panel 10, a support frame 20, a storage battery 30, a distribution board 40, and a second distribution board 39.

[0029] The solar panel 10 converts solar energy into, for example, several kW of electrical energy using a solar cell. The solar panel 10 includes a solar cell. The solar cell converts solar energy into electrical energy.

[0030] FIG. 3 is a front view of the solar panel 10. As shown in Fig. 3, the solar panel 10 has a plurality of (five in Fig. 3) separation panels 11. Each of the plurality of separation panels 11 extends vertically as a first direction. The plurality of separation panels 11 are arranged horizontally as a second direction perpendicular to the first direction. By configuring the solar panel 10 with a plurality of separation panels 11, each separation panel 11 becomes small and lightweight, making it possible to carry it manually and improving workability.

[0031] Each separation panel 11 has an opening 12 and a handle 13. The openings 12 are provided at positions away from both ends in the longitudinal direction, which is the longitudinal direction of the separation panel 11. The openings 12 extend in the horizontal direction. The handle 13 is located closer to the end in the longitudinal direction than the openings 12. A worker can hold the handle 13 by inserting his or her fingers into the opening 12. Being able to hold the handle 13 makes the separation panel 11 easier to carry manually, improving workability.

[0032] The support frame 20 supports the solar panel 10. The support frame 20 is removably fixed to the temporary building 100. When the support frame 20 is fixed to the temporary building 100, the support frame 20 supports the solar panel 10 along a wall surface 101 of the temporary building 100. The support frame 20 can be detached from the temporary building 100 to remove the solar panel 10 from the temporary building 100.

[0033] [First embodiment of support frame] The support frame 20 is configured by combining two vertical single pipes 21, four horizontal single pipes 22, a clamp 23, a catch clamp 24, a clamp member 25, a jack member 26, and a base plate 27. Note that the clamp 23, the catch clamp 24, and the clamp member 25 are omitted from FIG. 3.

[0034] The vertical single pipes 21 are arranged on both horizontal sides of the support frame 20. The horizontal single pipes 22 are arranged at intervals in the vertical direction. The vertical single pipes 21 and the horizontal single pipes 22 are connected at their intersections by clamps 23 to form a lattice. The support frame 20 is fixed to the temporary building 100 by fixing the upper sides of the vertical single pipes 21 to the horizontal furring strips 102 with catch clamps 24.

[0035] The solar panel 10 is fixed to the horizontal single pipe 22 with clamp members 25, and is thereby supported on the support frame 20 parallel to the wall surface 101. The solar panel 10 is fixed to the horizontal single pipe 22 with clamp members 25 at two points, on both ends in the vertical direction. The clamp members 25 fixed to the horizontal single pipe 22 are inserted into the openings 12 and fixed to the handles 13 of the solar panel 10. By inserting the clamp members 25 into the openings 12 and fixing them to the handles 13, the solar panel 10 (separate panel 11) can be easily fixed to the support frame 20.

[0036] The jack members 26 are respectively installed on the underside of the two vertical single pipes 21. The jack members 26 support the support frame 20 from below. The floor plates 27 are respectively installed on the underside of the jack members 26. The floor plates 27 support the jack members 26 from below. The jack members 26 supported from below by the floor plates 27 support the two vertical single pipes 21 that constitute the support frame 20 from below, thereby allowing the load of the solar panel 10 and the support frame 20 to be evenly transmitted to the ground.

[0037] The height of the lower end of the solar panel 10 supported by the support frame 20 via the jack members 26 and the base plate 27 is preferably 30 cm or more above the ground, from the viewpoint of protecting the solar panel 10.

[0038] The solar panel 10 attached to the wall surface 101 via the support frame 20 is installed from the ground surface, so the scaffolding used for installation is at a height that can be easily reached with, for example, a stepladder of about 1 m in height, making it possible to continuously check the solar panel 10 from the ground after it is installed, thereby reducing the risk of danger during daily maintenance and inspection.

[0039] The storage battery 30 stores the power generated by the solar panel 10. The storage battery 30 can supply the stored power to an electric device 103 provided in the temporary building 100. An example of the electric device 103 is an LED lighting device or the like.

[0040] The storage battery 30 stores the power generated by the solar panel 10 via wiring 31. The storage battery 30 is placed inside the temporary building 100. By placing the storage battery 30 inside the temporary building 100, deterioration of the storage battery 30 is reduced and power can be supplied outside the power supply system 1. The storage battery 30 is a portable type that can be carried by human power.

[0041] The wiring 31 connecting the solar panel 10 installed outdoors and the storage battery 30 arranged indoors is drawn indoors through a piping box 35 provided on a wall surface 101. It is preferable to seal the holes watertight and install a waterproof case from outdoors to prevent rainwater and the like from entering. The distance between the solar panel 10 supported by the support frame 20 and the temporary building 100 is preferably about 20 cm for wiring to the storage battery 30. A direct current is input from the solar panel 10 to the storage battery 30. The storage battery 30 outputs an alternating current to the distribution board 40 by performing a direct current-alternating current conversion.

[0042] The storage battery 30 has, for example, a chopper circuit 33 and an inverter circuit 34. Fig. 4 shows an example of the chopper circuit 33 and the inverter circuit 34. The chopper circuit 33 converts the DC current from the solar panel 10 into a DC current suitable for the inverter circuit 34. The inverter circuit 34 converts the DC current output from the chopper circuit 33 into an AC current of a commercial frequency.

[0043] A second distribution board 39 is provided for drawing in commercial power from a commercial power source. Power is transmitted from the distribution board 39 to a distribution board 40. This is to switch to commercial power from the distribution board 40 to supply power to the temporary building 100 when the power supply from the storage battery 30 is insufficient according to the amount of power stored therein.

[0044] The distribution board 40 is provided between the storage battery 30 and the electrical equipment 103. The distribution board 40 is installed in the temporary building 100. The distribution board 40 may be installed indoors in the temporary building 100, but is installed outdoors in this embodiment. The distribution board 40 is connected to the storage battery 30 and a commercial power source 104 as a second power source different from the storage battery 30. The distribution board 40 is connected to the storage battery 30 via wiring 32. The distribution board 40 receives power from a power company via the connected commercial power source 104. An AC current of a specified voltage is input to the distribution board 40 from the commercial power source 104 via a distribution board 39.

[0045] The distribution board 40 selects a source of power to be supplied to the electric device 103 depending on the amount of power stored in the storage battery 30. For example, when the amount of power stored in the storage battery 30 is sufficient to supply power to the electric device 103 during the daytime, the distribution board 40 preferentially selects the storage battery 30 as the source of power. For example, when the amount of power stored in the storage battery 30 is insufficient to supply power to the electric device 103 during the nighttime, the distribution board 40 selects the commercial power source 104 as the source of power and switches from the storage battery 30. The power of the source selected by the distribution board 40 is supplied to the electric device 103.

[0046] Since the distribution board 40 receives AC current from the storage battery 30 and the commercial power source 104, it does not incorporate a power conditioner (PCS) that converts DC current to AC current. Therefore, the distribution board 40 has an AC power transfer switch as a relay for selecting and switching the commercial power source 104 as a power source for nighttime use, for example. FIG. 5 shows an example of an external AC power priority switching relay circuit diagram that constitutes the AC power transfer switch. By using the AC power transfer switch in the distribution board 40 in the temporary building 100, costs can be significantly reduced compared to the case where an expensive power conditioner is incorporated in the distribution board 40.

[0047] In the power supply system 1 for the temporary building 100 of this embodiment, the solar panels 10 supported by the support frame 20 are installed along the wall surface 101 of the temporary building 100, making installation and removal easier than when the solar panels 10 are installed on the roof surface. Also, in the power supply system 1 for the temporary building 100 of this embodiment, the support frame 20 is configured by connecting the vertical single pipe 21 and the horizontal single pipe 22 using clamps 23, making assembly and disassembly easy.

[0048] Furthermore, in the power supply system 1 for the temporary building 100 of this embodiment, the storage battery 30 and the commercial power source 104 are connected to the distribution board 40, and the source of power supplied to the electrical equipment 103 is selected according to the amount of power stored in the storage battery 30, so that, for example, power generated by the solar panel 10 and stored in the storage battery 30 is supplied to the electrical equipment 103 during the day, and power from the commercial power source 104 is supplied to the electrical equipment 103 at night. In the power supply system 1 for the temporary building 100 of this embodiment, power generated by the solar panel 10 is used, so power consumption from the commercial power source 104 can be reduced, contributing to a reduction in CO2 emissions.

[0049] [Second embodiment of the support frame] A support frame 20A according to the second embodiment will be described with reference to FIGS. In these figures, the same elements as those in the first embodiment shown in Figures 1 to 5 are denoted by the same reference numerals, and their description will be omitted. In Figure 6 and subsequent figures, in order to facilitate understanding of the support frame 20A, the solar panel 10 is shown by a two-dot chain line, and the support frame 20A located on the back side of the solar panel 10 is shown by a solid line.

[0050] FIG. 6 is a front view of a support frame 20A and a solar panel 10 according to the second embodiment. FIG. 7 is a side view of a support frame 20A and a solar panel 10 according to the second embodiment.

[0051] 6 and 7, the support frame 20A has single horizontal pipes 22A to 22C. The single horizontal pipe 22A is disposed at the upper end position in the height direction of the solar panel 10. Fig. 8 is a side view showing the connection structure of the single horizontal pipes 22A.

[0052] As shown in Fig. 8, the single horizontal pipe 22A is connected to the single vertical pipe 21 by an orthogonal clamp 23A. In addition, the solar panel 10 supported by a flexible clamp 23B inserted into the opening 12 is fixed to the single horizontal pipe 22A via a cushioning material. The single horizontal pipe 22B is disposed at the lower end position of the solar panel 10 in the height direction. The solar panel 10 supported by the flexible clamp 23B inserted into the opening 12 is fixed to the single horizontal pipe 22B, similar to the single horizontal pipe 22A.

[0053] A plurality of horizontal single pipes 22C (five in FIG. 6) are disposed at intervals in the height direction between the horizontal single pipes 22A and 22B. FIG. 9 is a side view showing the connection structure of the horizontal single pipes 22C.

[0054] 9, the horizontal single pipe 22C is connected to the vertical single pipe 21 by an orthogonal clamp 23C. A gap adjusting material 23D is provided between the horizontal single pipe 22C and the solar panel 10. The solar panel 10 is fixed from the back side to each of the horizontal single pipes 22C via the gap adjusting material 23D by a binding string 23E.

[0055] In the support frame 20A of the second embodiment, in addition to obtaining the same functions and effects as the support frame 20 of the first embodiment, the solar panel 10 can be easily fixed to and detached from the horizontal single pipe 22C using the binding string 23E.

[0056] [Third embodiment of support frame] A support frame 20B according to the third embodiment will be described with reference to FIGS. In these figures, the same elements as those in the second embodiment shown in FIGS. 6 to 9 are designated by the same reference numerals, and the description thereof will be omitted.

[0057] In the above-mentioned base 1 embodiment and second embodiment, a configuration in which the solar panel 10 is fixed to a horizontal single tube as a base has been exemplified, but in this embodiment, a configuration in which the solar panel 10 is fixed to a vertical single tube as a base will be described.

[0058] As shown in FIG. 10, the support frame 20B has horizontal single tubes 22D and 22E and a plurality of vertical single tubes 21A. 11, the horizontal single pipe 22D is connected to the vertical single pipe 21 from the rear side by an orthogonal clamp 23F. The horizontal single pipe 22E is connected to the vertical single pipe 21 from the rear side by an orthogonal clamp (not shown).

[0059] A plurality of vertical single pipes 21A (six in FIG. 10) are arranged at intervals in the horizontal direction. The vertical single pipes 21A are arranged along the horizontal edges of the solar panel 10. The vertical single pipes 21A are connected to the horizontal single pipes 22D and 22E from the front side by orthogonal clamps 23G.

[0060] The upper end of the solar panel 10 is fixed to a catch clamp 23I connected to the horizontal single pipe 22D by a binding string 23H. The solar panel 10 is also fixed to each of the multiple vertical single pipes 21A by binding strings 23J at intervals in the height direction.

[0061] In the support frame 20B of the third embodiment, the solar panel 10 is based on a vertical single pipe, and can be easily fixed and removed by binding strings 23H and 23J.

[0062] [Fourth embodiment of the support frame] A support frame 20C according to the fourth embodiment will be described with reference to FIG. In this figure, the same elements as those in the second embodiment shown in FIGS. 6 to 9 are designated by the same reference numerals, and the description thereof will be omitted.

[0063] In the above first to third embodiments, a configuration in which a plurality of separation panels 11 each extending in a vertical direction are arranged in a horizontal direction has been exemplified. In this embodiment, however, a configuration in which a plurality of separation panels 11 each extending in a horizontal direction are arranged in a vertical direction will be described.

[0064] As shown in Fig. 12, the vertical single pipes 21 in the support frame 20C are disposed at a position separated in the horizontal direction from the window portion 105 of the temporary building 100. The separate panels 11 of the solar panel 10 are disposed so that they each extend in the horizontal direction. Three separate panels 11 are disposed side by side in the height direction above the window portion 105. Two separate panels 11 are disposed side by side in the height direction below the window portion 105.

[0065] The support frame 20C has a plurality of (seven in FIG. 12) horizontal single pipes 22F. The horizontal single pipes 22F are arranged along the edges of the separation panel 11 in the height direction. Each of the horizontal single pipes 22F is fixed to the vertical single pipe 21 by the orthogonal clamps described above. The solar panel 10 is fixed to each of the horizontal single pipes 22F by binding strings 23K at intervals in the horizontal direction.

[0066] In the support frame 20C of the fourth embodiment, by arranging the separation panel 11 at a position away from the window portion 105 of the temporary building 100 in the vertical direction, the separation panel 11 is positioned outside the window portion 105 of the temporary building 100, thereby preventing the obstruction of lighting into the interior of the building.

[0067] [Fifth embodiment of support frame] A support frame 20D according to the fifth embodiment will be described with reference to FIGS. In these figures, the same elements as those in the second embodiment shown in FIGS. 6 to 9 are designated by the same reference numerals, and the description thereof will be omitted.

[0068] In the above first to fourth embodiments, a configuration was illustrated in which the solar panel 10 is arranged parallel to the wall surface of the temporary building 100. However, in this embodiment, a configuration is described in which the angle of the solar panel 10 relative to the wall surface of the temporary building 100 is adjustable.

[0069] As shown in FIG. 13, the support frame 20D has two vertical single tubes 21B. The two vertical single pipes 21B are connected to the horizontal single pipes 22A to 22C to form a frame F that supports the solar panel 10.

[0070] The two vertical single pipes 21B are arranged adjacent to each other on the horizontal inside of the vertical single pipe 21. Each of the vertical single pipes 21B is connected to the adjacent vertical single pipe 21 by a flexible clamp 23L. As shown in FIG. 14, each of the vertical single pipes 21B can rotate around an axis extending in the horizontal direction at the flexible clamp 23L relative to the adjacent vertical single pipe 21. That is, the frame F supporting the solar panel 10 can rotate around an axis extending in the horizontal direction at the flexible clamp 23L relative to the vertical single pipe 21. The frame F supporting the solar panel 10 can be adjusted from a position F1 parallel to the wall surface of the temporary building 100 to a position F2 in which the lower end is inclined away from the wall surface.

[0071] A jack member 26A is detachably attached to the lower end of each of the two vertical single pipes 21B. When the frame F is at position F2, the inclination angle θ of the frame F can be adjusted by adjusting the length of the jack member 26A. The inclination angle θ can be adjusted as appropriate depending on the latitude of the installation position and the sunlight conditions due to surrounding buildings, etc., and may be adjusted between 20° and 40°, for example. When the frame F is at position F1, the jack member 26A is removed.

[0072] In the support frame 20D of the fifth embodiment, in addition to obtaining the same action and effect as the support frame 20 of the second embodiment, the solar panel 10 can be tilted via the frame F, making it possible to increase the amount of power generation compared to when the solar panel 10 is parallel to the wall surface.

[0073] [Sixth embodiment of the support frame] A support frame 20E according to the sixth embodiment will be described with reference to FIGS. In these figures, the same elements as those in the third embodiment shown in FIGS. 10 and 11 are designated by the same reference numerals, and the description thereof will be omitted.

[0074] In the above first to fifth embodiments, a configuration using a cylindrical single pipe has been exemplified, but in this embodiment, a configuration using a metal square pipe will be described.

[0075] 15, the support frame 20E has vertical square pipes 21C and 21D and horizontal square pipes 22M and 22N. The vertical square pipes 21C and 21D and the horizontal square pipes 22M and 22N are formed of aluminum, for example.

[0076] The vertical angle pipes 21C are disposed at both lateral ends of the support frame 20E. As shown in Fig. 16, the vertical angle pipes 21C are fixed by U-bolts 22P to a horizontal single pipe 22D connected to the vertical single pipe 21 by an orthogonal clamp 23C at the upper end. The vertical angle pipes 21C are fixed by U-bolts to a horizontal single pipe 22E connected to the vertical single pipe 21 at the lower end.

[0077] The horizontal angle pipe 22M is suspended between the vertical angle pipes 21C arranged at both ends in the horizontal direction below the horizontal single pipe 22D. The horizontal angle pipe 22N is suspended between the vertical angle pipes 21C arranged at both ends in the horizontal direction above the horizontal single pipe 22E.

[0078] A plurality of vertical angle pipes 21D (four in FIG. 10) are arranged at intervals in the horizontal direction. The vertical angle pipes 21D are arranged along the edges of the solar panel 10 in the horizontal direction.

[0079] The upper end of the solar panel 10 is fixed to the horizontal angle pipe 22M by a binding string 23H. The horizontal edges of the solar panel 10 are fixed to the vertical angle pipe 21C and the vertical angle pipe 21D by binding strings 23J.

[0080] In the support frame 20E of the sixth embodiment, the vertical square pipes 21C, 21D and the horizontal square pipes 22M, 22N made of aluminum are used, so that the weight can be reduced compared to the case where only steel pipes are used.

[0081] Although the preferred embodiment of the present invention has been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to the examples. The shapes and combinations of the components shown in the above examples are merely examples, and various modifications can be made based on design requirements, etc., without departing from the spirit of the present invention.

[0082] For example, in the above embodiment, the commercial power source 104 is connected to the distribution board 40 as the second power source, but the present invention is not limited to this configuration. If it is possible to supply power to the electrical device 103 at night or the like, a configuration in which another power source is connected may be used. Also, a configuration in which an extended battery is connected to the storage battery 30 to increase the amount of stored power may be used.

[0083] In the above embodiment, the configuration in which power is supplied from the distribution board 40 to one temporary building 100 has been exemplified, but the present invention is not limited to this configuration. For example, as shown in Fig. 17 as a modified example, the distribution board 40 may have a configuration having multiple power distribution units 40A, 40B, and 40C that distribute power to different supply destinations. The power distribution unit 40A supplies power to a building such as a temporary office, for example. The power distribution unit 40B supplies power to a facility building, for example. The power distribution unit 40C supplies power as wireless power supply, for example.

[0084] The Sustainable Development Goals (SDGs) are among the 17 international goals adopted at the United Nations Summit in September 2015. The power supply system for temporary buildings according to this embodiment can contribute to achieving the 17 SDGs goals, for example goal 13: "Take urgent action to combat climate change."
