DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, embodiments of a solar panel, a solar panel support member, a solar panel installation support system, and a solar panel installation method according to the present invention will be described with reference to the drawings. Note that the drawings attached to this specification are all schematic diagrams, and the shape, scale, aspect ratio, etc. of each part have been modified or exaggerated from the actual product in consideration of ease of understanding, etc. Furthermore, hatching indicating cross sections of components has been omitted as appropriate in the drawings.

[0013] [Overall configuration of the solar panel installation support system Sa] FIG. 1 is a diagram showing an example of the overall configuration of a solar panel installation support system Sa according to an embodiment. Figures 2(A) to (D) are diagrams showing an example of construction to which the solar panel installation support system Sa of Figure 1 is applied. Note that in Figures 2(A) to (D), only the installation object 200 is shown to the extent necessary to explain the panel installation construction. The same applies to the other figures.

[0014] The solar panel installation support system Sa in Fig. 1 is an information processing system that supports the installation of solar panels (hereinafter also referred to as "panel installation work") on objects (hereinafter also referred to as "installation objects") on which solar panels are to be installed, such as roofing materials and wall materials. The combination of solar panels and installation objects to which the solar panel installation support system Sa is applicable is not particularly limited. The solar panel installation support system Sa can be applied to various combinations of solar panels and installation objects.

[0015] Examples of solar panels to which the solar panel installation support system Sa can be applied include flexible solar panels made of polyethylene terephthalate or the like, and solar panels with inflexible glass substrates. Examples of installation targets to which the solar panel installation support system Sa can be applied include flat roofing materials with a horizontal or slight water gradient (hereinafter sometimes referred to as "flat roofs"). Examples of roofing materials and wall materials (hereinafter sometimes referred to as "folded plate roofs") that are made uneven by bending metal plates (hereinafter sometimes referred to as "folded plate walls") are also examples. Examples of structures include greenhouses, tents, and the like, which are made of predetermined frame members, film members, sheet members, and the like.

[0016] The solar panel installation support system Sa can be applied to any of the panel installation works shown in, for example, Figures 2(A) to 2(D). For example, Figure 2(A) shows an example of panel installation work in which solar panels 100 are installed on a flat roof as the installation object 200. Also, Figure 2(B) shows an example of panel installation work in which solar panels 100 are installed on a folded-plate roof as the installation object 200. Also, Figure 2(C) shows an example of panel installation work in which solar panels 100 are installed on a greenhouse as the installation object 200. Also, Figure 2(D) shows an example of panel installation work in which solar panels 100 are installed on a wall material as the installation object 200. Details of the panel installation work shown in Figures 2(A) to 2(D) will be described later with reference to specific examples in Figures 6 to 9.

[0017] As shown in FIG. 1, the solar panel installation support system Sa is configured by connecting a management server 1, an installer terminal 2, and a user terminal 3 via a network N via wired or wireless connections. The management server 1 is an information processing device that serves as a server that manages the entire solar panel installation support system Sa. The installer terminal 2 is an information processing device operated by an installer who performs panel installation work. The user terminal 3 is an information processing device operated by a user of the solar panel. The network N is, for example, the Internet, a LAN (Local Area Network), or a VPN (Virtual Private Network), etc.

[0018] (Management Server 1) The management server 1 constituting the solar panel installation support system Sa transmits various types of information to the installer terminal 2, the user terminal 3, and the outside, and enables various processes to be performed. The management server 1 also acquires various types of information transmitted from the installer terminal 2, the user terminal 3, and the outside, and enables various processes to be performed.

[0019] For example, the management server 1 acquires information relating to the specifications of the solar panels to be installed on the installation object (hereinafter also referred to as "panel specification information") transmitted from the installer terminal 2. The panel specification information includes, for example, information relating to the size and weight of the solar panels. Furthermore, if the solar panels are flexible solar panels, the panel specification information includes, for example, information relating to the flexibility of the solar panels, including the maximum bending angle of the solar panels.

[0020] Furthermore, when it is difficult to directly attach a solar panel to the installation object, such as when the installation object is a folded-plate roof or a vinyl greenhouse, a rod-shaped or strip-shaped support member may be disposed to support the solar panel and be detachably attached to the installation object. Examples of the support member include a metal or resin crosspiece, a resin or cloth band, or a resin or cloth belt. For this reason, the panel specification information acquired by the management server 1 may include information regarding the support member disposed between the solar panel and the installation object. The information regarding the support member may include, for example, information regarding the rigidity of the support member.

[0021] The management server 1 generates information on the panel installation construction mode (hereinafter also referred to as "construction mode information") based on the acquired panel specification information. The construction mode information includes, for example, information on the arrangement of adhesive members (hereinafter referred to as "adhesive" or "adhesive members") for adhering the solar panel to the installation object, such as the spacing of the adhesive member, the adhesive area, and the adhesive application range, which are arranged between the solar panel and the installation object. By referring to the generated construction mode information, the installer can smoothly carry out panel installation construction. The adhesive area included in the construction mode information is the adhesive area for which the installation mode generation unit 35 (described later) has determined that the adhesive stress level is within the allowable range.

[0022] The adhesive member disposed between the solar panel and the installation object is an important component for stably installing the solar panel on the installation object, and is composed of, for example, an adhesive or double-sided tape. When the adhesive member is composed of an adhesive, a filler having adhesive properties is also included in the adhesive. The properties of the adhesive used as the adhesive member are not particularly limited, but it is desirable that it be able to firmly adhere the solar panel to the installation object. For this reason, silicone-based adhesives and fillers with the following properties are preferred. That is, those that are resistant to high temperatures and high humidity, durable to ultraviolet light, resistant to expansion and contraction, able to maintain high elasticity for a long period of time, highly viscous, and able to fill gaps with the adherend and maintain adhesion are preferred.

[0023] The information on the arrangement of adhesive members included in the installation mode information includes information on the mode of adhesive members (hereinafter also referred to as "first adhesive members") that are arranged so as to extend in a strip-like manner in a direction perpendicular to the water gradient direction of the solar panel. The information on the arrangement of adhesive members also includes information on the mode of adhesive members (hereinafter also referred to as "second adhesive members") that are arranged so as to extend in a strip-like manner in the water gradient direction of the solar panel.

[0024] Furthermore, if the location where panel installation work is to be performed is an area with heavy snowfall, the snow load capacity of the solar panel installation location may be included in the installation mode information generated by management server 1. In this case, the snow load capacity of the solar panel installation location is calculated based on, for example, information on the flexibility of the solar panel included in the panel specification information.

[0025] The management server 1 also acquires information on the construction conditions for panel installation work (hereinafter also referred to as "construction condition information") transmitted from the constructor terminal 2. The construction condition information includes, for example, information on the installation conditions of the solar panels (hereinafter also referred to as "installation condition information"), such as the season in which the panel installation work will be performed, the expected temperature at the construction site, the expected wind conditions (such as reference wind speed), the ground surface roughness, the height from the ground surface of the position where the solar panels will be installed, and the specifications of the adhesive materials. The construction condition information also includes information on the specifications of the installation object (hereinafter also referred to as "installation object specification information"), such as the shape and inclination angle of the installation object. The installation condition information can include any type of information, such as a character string specifying the installation conditions (for example, a place name), a selection (for example, whether the area is a heavy snow area or not), or a specific numerical value (for example, a specific numerical value of the snow load to be assumed).

[0026] The management server 1 generates construction mode information based on the acquired panel specification information and construction condition information. The construction mode information generated based on the panel specification information and construction condition information includes, for example, the maximum instantaneous wind speed at the construction site, a wind pressure load coefficient calculated based on the height of the solar panel installation location, etc. Furthermore, when the construction condition information includes installation object specification information, the management server 1 generates construction mode information that takes into account the specifications of the installation object.

[0027] The management server 1 also acquires information regarding the desired amount of power generation by solar power generation using the solar panels (hereinafter also referred to as "desired power generation amount information") desired by the user of the solar panel, transmitted from the user terminal 3. The desired power generation amount information includes, for example, the maximum value of the amount of power generation desired by the user as the amount of power generation by solar power generation using the solar panels.

[0028] The management server 1 generates construction mode information based on the acquired panel specification information and desired power generation information. The construction mode information generated based on this information includes, for example, the snow load capacity of the solar panel installation location and the acceptable risk of failure, such as damage to the solar panel due to snow, taken into account the user's desired power generation amount. The management server 1 transmits the generated construction mode information to the installer terminal 2. The configuration and processing of the management server 1 will be described in detail later.

[0029] (Constructor terminal 2) The installer terminal 2 constituting the solar panel installation support system Sa is capable of transmitting various types of information to the management server 1 and the outside. The installer terminal 2 also acquires various types of information transmitted from the management server 1 and the outside and performs various processes. For example, the installer terminal 2 transmits panel specification information to the management server 1. The installer terminal 2 also transmits installation condition information to the management server 1. The installer terminal 2 also acquires installation mode information transmitted from the management server 1 and displays it on a display or the like.

[0030] (User terminal 3) The user terminal 3 constituting the solar panel installation support system Sa is capable of transmitting various types of information to the management server 1 and to the outside. The user terminal 3 is also capable of acquiring various types of information transmitted from the management server 1 and to the outside and performing various processes. For example, the user terminal 3 transmits desired power generation amount information to the management server 1.

[0031] [Hardware configuration] (Hardware configuration of Management Server 1) FIG. 3 is a block diagram showing an example of the hardware configuration of the management server 1 that constitutes the solar panel installation support system Sa of FIG. The management server 1 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a bus 14, an input / output interface 15, an output unit 16, an input unit 17, a memory unit 18, a communication unit 19, and a drive 20.

[0032] The CPU 11 executes various processes in accordance with programs recorded in the ROM 12 or programs loaded from the storage unit 18 into the RAM 13. The RAM 13 also stores data and the like required for the CPU 11 to execute various processes. The CPU 11, the ROM 12, and the RAM 13 are interconnected via a bus 14. An input / output interface 15 is also connected to this bus 14.

[0033] The input / output interface 15 is connected to an output unit 16, an input unit 17, a memory unit 18, a communication unit 19, and a drive 20. The output unit 16 is composed of a display, a speaker, etc., and outputs various types of information as images and sounds. The input unit 17 is composed of a button, a keyboard, a mouse, a touch panel, etc., and accepts input of various types of information. The memory unit 18 is composed of a hard disk, a DRAM (Dynamic Random Access Memory), etc., and stores various types of data. The communication unit 19 enables communication with other devices via a network N (see FIG. 1) such as the Internet.

[0034] Removable media 21, such as a magnetic disk, optical disk, magneto-optical disk, or semiconductor memory, is appropriately attached to the drive 20. Programs read from the removable media 21 by the drive 20 are installed in the storage unit 18 as needed. The removable media 21 can also store various data stored in the storage unit 18 in the same way as the storage unit 18.

[0035] (Hardware configuration of the installer terminal 2 and the user terminal 3) The contractor terminal 2 and the user terminal 3 each include a CPU, ROM, RAM, bus, input / output interface, output unit, input unit, memory unit, communication unit and drive (not shown) that correspond to the CPU 11, ROM 12, RAM 13, bus 14, input / output interface 15, output unit 16, input unit 17, memory unit 18, communication unit 19 and drive 20 in Figure 3, respectively.

[0036] [Functional configuration of management server 1] FIG. 4 is a functional block diagram showing an example of the functional configuration of the management server 1 of FIG. When the CPU 11 of the management server 1 operates, a panel specification acquisition unit 31 as a panel specification acquisition means, a construction condition acquisition unit 32 as a construction condition acquisition means, a desired power generation amount acquisition unit 33 as a desired power generation amount acquisition means, a management unit 34 that manages various information, a construction mode generation unit 35 as a generation means, and a transmission control unit 36 ​​function.

[0037] Furthermore, various databases are provided in the storage unit 18 of the management server 1. For example, a panel specification DB 41 that stores panel specification information, a construction condition DB 42 that stores construction condition information, a desired power generation amount DB 43 that stores desired power generation amount information, and a construction mode DB 44 that stores construction mode information are provided.

[0038] The panel specification acquisition unit 31 acquires the panel specification information transmitted from the installer terminal 2 to the management server 1 via the communication unit 19 (see FIG. 3). The construction condition acquisition unit 32 acquires the construction condition information transmitted from the constructor terminal 2 to the management server 1 via the communication unit 19. The desired power generation amount obtaining unit 33 obtains, via the communication unit 19, desired power generation amount information transmitted from the user terminal 3 to the management server 1.

[0039] The management unit 34 stores and manages the panel specification information acquired by the panel specification acquisition unit 31 in a panel specification DB 41 of the storage unit 18 (see FIG. 3). The management unit 34 also stores and manages the construction condition information acquired by the construction condition acquisition unit 32 in a construction condition DB 42 of the storage unit 18. The management unit 34 also stores and manages the desired power generation amount information acquired by the desired power generation amount acquisition unit 33 in a desired power generation amount DB 43 of the storage unit 18. The management unit 34 also stores and manages the construction mode information generated by the construction mode generation unit 35 (described later) in a construction mode DB 44 of the storage unit 18. The management unit 34 can store and manage information capable of identifying at least a portion of the construction condition information (for example, in the case of snow load, information correlating the region name, whether it is a heavy snow area or not, specific numerical values ​​of the assumed snow load, etc.) based on the information for identifying the construction conditions in a predetermined DB (not shown) of the storage unit 18. In this case, the construction condition acquisition unit 32 acquires information for identifying the construction condition information (which may be a portion of the construction condition information). The management unit 34 can identify and manage at least a portion of the construction conditions based on the information for identifying the construction conditions acquired by the construction condition acquisition unit 32.

[0040] The installation condition information may include, for example, a structural overview of the solar panel, calculation details, calculated wind pressure load, snow load, earthquake load, materials used and allowable stress, adhesive performance, adhesive allowable values, a structural overview of the installation object, shape of calculated components and allowable stress, adhesive distribution overview, etc. Of these items, items other than those related to adhesives comply with the standard JIS C 8955 (Design load calculation method for solar cell array supports).

[0041] The structural overview of the solar panel includes the specifications of the solar panel, various standards used for calculations, the height at which the solar panel is to be installed, etc. Items related to the structural overview of the solar panel may also include the finishing state of the location (object to be installed) where the solar panel is to be installed.

[0042] The calculation involves the combination of load conditions and loads, specifically the assumed conditions (normal, snowy, stormy, earthquake, etc.), load calculation patterns for normal areas, load calculation patterns for heavy snow areas, etc.

[0043] The design wind load is calculated based on the wind force coefficient, design velocity pressure, swept area, and a formula. The design velocity pressure is calculated based on the design standard wind speed, environmental coefficient, use coefficient, and a formula for the area where the solar panels will be installed.

[0044] Snow load is calculated based on the snow load, slope factor, vertical snow depth on the ground, snow area, and a formula. The slope factor is calculated based on the slope (degrees) of the snow surface multiplied by a coefficient, and a formula.

[0045] Earthquake loads are divided into design earthquake loads for general regions and design earthquake loads for heavy snow areas, and are calculated based on the design horizontal seismic intensity, dead load, snow load multiplied by a coefficient, and a calculation formula. The materials used and allowable stress levels are the materials used for the object to be installed and their standard strength, etc.

[0046] The adhesive performance includes processing conditions, 50% tensile stress, maximum tensile stress, elongation at maximum load, etc. In addition to the adhesive performance, the minimum amount (width) of adhesive to be applied is also set. The allowable value of an adhesive is the allowable stress of the adhesive, which is the stress against the force that tries to peel the bonded parts apart. The allowable stress of the adhesive is calculated by multiplying the adhesive manufacturer's catalog value by a safety factor.

[0047] The shape and allowable stress of the calculation components include the weight and size of the solar panel, snow load, earthquake load, and the stress of the object to be installed (e.g., roof material). The structural outline of the installation object is the height, slope, etc. of the installation object (for example, roof material). The adhesive distribution summary is an estimated adhesive area (hereinafter also referred to as the "set adhesive area") based on the number of adhesive lines, adhesive width, adhesive length, and adhesive spacing that are set according to the actual situation of the installation object at the site. The set adhesive area may be obtained from the construction mode information managed in the construction condition DB 42.

[0048] The construction mode generation unit 35 generates construction mode information based on the panel specification information. The construction mode generation unit 35 also generates construction mode information based on the panel specification information and construction condition information. The construction mode generation unit 35 also generates construction mode information based on the panel specification information and desired power generation information. The construction mode generation unit 35 also generates construction mode information based on the panel specification information, construction condition information, and desired power generation information.

[0049] Specifically, for example, the installation mode generation unit 35 generates installation mode information based on the size and weight of the solar panel identified from the panel specification information and the installation environment of the solar panel identified from the installation condition information. The installation environment of the solar panel includes, for example, a standard wind speed, a standard amount of snow accumulation, the height of the installation location from the ground surface, and the ground surface roughness. The installation mode information generated by the installation mode generation unit 35 includes information on the arrangement of adhesive members, such as the spacing and adhesive area of ​​the adhesive members arranged between the solar panel and the installation target object. The information on the arrangement of adhesive members also includes the number of bands of adhesive members (hereinafter sometimes referred to as "lines"), the spacing between the lines, the width of the lines, and so on.

[0050] Of the installation mode information generated by the installation mode generation unit 35, information regarding the placement of adhesive members is generated based on the adhesion area calculated by, for example, the following method. That is, the adhesion area is calculated to be larger as the weight of the solar panel 100 increases. The adhesion area is also calculated to be larger as the temperature at the installation location of the solar panel 100 decreases. The adhesion area is also calculated to be larger as the water gradient angle (installation angle) of the solar panel 100 increases. The adhesion area is also calculated to be larger as the reference wind speed increases. The adhesion area is also calculated to be larger as the height from the ground surface of the installation location of the solar panel 100 increases.

[0051] The construction mode generating unit 35 can determine whether the construction mode information satisfies the construction conditions. As will be described in detail later, the construction mode generating unit 35 can output construction mode information that satisfies the construction conditions by repeatedly generating construction mode information until the generated construction mode information satisfies the construction conditions. Below, an example will be described in which it is determined whether the adhesive stress level is within the range of the allowable value of the adhesive (an example of a construction condition) based on the installation condition information among the construction condition information.

[0052] Based on the acquired installation condition information, the construction mode generation unit 35 calculates the design load value to be applied to the installed solar panel 100. Examples of the design load value calculated by the construction mode generation unit 35 include a design wind pressure load value, a design snow load value, and a design earthquake load value.

[0053] The design wind load value Wa (N) is calculated using formula (1). Wa = Ca × qp × Aa (1) Where, Ca: wind force coefficient, qp: design velocity pressure (N / m 2 ), Aa: swept area (m 2 )

[0054] The design snow load value Sp (N) is calculated using formula (2). Sp = Zs × P / 1000 (2) Where, Zs: snow depth (cm), P: unit load (N / cm / m 2 )

[0055] The design seismic load value Kp (N) is calculated using formula (3) or (4). Kp (general region) = kp × G (3) Kp (heavy snow region) = kp × (G + 0.35S) (4) Here, kp is the design horizontal seismic intensity, G is the dead load (N), and S is the snow load (N).

[0056] The construction mode generating unit 35 also calculates the adhesive stress of the adhesive applied to the object to be installed based on the predetermined set adhesive area extracted from the installation condition information and the calculated design load value. The construction mode generating unit 35 also determines whether the calculated adhesive stress is within the range of the adhesive's allowable value.

[0057] When the construction mode generating unit 35 determines that the adhesive stress level is within the range of the adhesive's tolerance, it can transmit the generated construction mode information to the contractor terminal 2 as adoptable construction mode information. When the construction mode generating unit 35 determines that the adhesive stress level is not within the range of the adhesive's tolerance, it generates new construction mode information for a construction mode that can ensure a larger adhesive area, and repeatedly determines whether the construction conditions are met. That is, the construction mode generating unit 35 generates and outputs construction mode information that meets the construction conditions.

[0058] Furthermore, the construction mode generating unit 35 can output information indicating that the construction mode information satisfies the construction conditions together with the construction mode information. Specifically, for example, the construction mode generating unit 35 calculates the adhesive stress level to the installation object based on the generated adhesive area, determines whether the adhesive stress level is within the range of the allowable value for the adhesive, and transmits the determination result (including an explanation of the determination process) to the constructor terminal 2. Details of the processing flow will be described later.

[0059] The transmission control unit 36 ​​controls the transmission of various information via the communication unit 19. For example, the transmission control unit 36 ​​controls the transmission of construction mode information managed by the management unit 34 to the contractor terminal 2.

[0060] [Management Server 1 processing flow] FIG. 5 is a flowchart showing an example of the processing flow of the management server 1. When the panel specification information is transmitted from the installer terminal 2 (YES in step S1), the management server 1 acquires the transmitted panel specification information (step S2) and proceeds to the determination process of step S3. On the other hand, when the panel specification information is not transmitted (NO in step S1), the management server 1 repeats the determination process of step S1.

[0061] When construction condition information is transmitted from the constructor terminal 2 (YES in step S3), the management server 1 acquires the transmitted construction condition information (step S4) and proceeds to the determination process of step S5. On the other hand, when construction condition information is not transmitted (NO in step S3), the management server 1 proceeds to the determination process of step S5.

[0062] When the desired power generation amount information is transmitted from the user terminal 3 (YES in step S5), the management server 1 acquires the transmitted desired power generation amount information (step S6) and proceeds to step S7. On the other hand, when the desired power generation amount information is not transmitted (NO in step S5), the management server 1 proceeds to the processing of step S7.

[0063] The management server 1 generates construction mode information based on information including at least the panel specification information (step S7). Then, the management server 1 transmits the generated construction mode information to the installer terminal 2 (step S8). This ends the processing of the management server 1 (END).

[0064] [Specific example] (Example of panel installation construction 1) FIG. 6 is a diagram showing a specific example of the panel installation work of FIG. 2(A). 6 shows a specific example of panel installation work in which a solar panel 100 is installed on an installation object 200, which is a flat roof with a slight water gradient. A first adhesive member 411 and second adhesive members 421, 422, 423, 424, 425, and 426 for adhering the solar panel 100 to the installation object 200 are arranged between the solar panel 100 and the installation object 200. It is assumed that a waterproof layer is arranged on the surface of the installation object 200 and that the surface is further painted.

[0065] In the example of FIG. 6, the first adhesive member 411 is arranged so as to extend in a band-like shape in a direction perpendicular to the water gradient direction at the abovewater edge of the solar panel 100 in the water gradient direction. Meanwhile, no first adhesive member extending in a band-like shape in a direction perpendicular to the water gradient direction is arranged at the belowwater edge of the solar panel 100 in the water gradient direction. Furthermore, the second adhesive members 421-426 are arranged in parallel so as to extend in a band-like shape in the water gradient direction of the solar panel 100. The abovewater end of each of the second adhesive members 421-426 in the water gradient direction is in contact with the first adhesive member 411. In the panel installation construction shown in FIG. 6, the first adhesive member 411 and the second adhesive members 421-426 maintain a gap between the belowwater edge of the solar panel 100 in the water gradient direction and the installation object 200.

[0066] Arranging the first adhesive member 411 and the second adhesive members 421-426 in the configuration shown in FIG. 6 provides the following effects. Specifically, the first adhesive member 411 prevents unnecessary gaps from being formed between the edge portion 101 of the solar panel 100 on the water-side in the water gradient direction and the installation object 200. This prevents rainwater, dust, and the like from infiltrating the back surface of the solar panel 100 (the surface facing the installation object 200). As a result, deterioration of the waterproof layer and coating provided on the surface of the installation object 200 is suppressed. For example, in a harsh environment where the solar panel 100 is installed, such as below-freezing temperatures in winter, rainwater may freeze and expand, placing a load on the solar panel 100. In contrast, when the first adhesive member 411 is arranged as shown in FIG. 6, the infiltration of rainwater is suppressed, thereby reducing the risk of the solar panel 100 being subjected to a load.

[0067] Furthermore, each of the second adhesive members 421-426 prevents unnecessary gaps from being formed between the solar panel 100 and the installation object 200 where it is arranged. Furthermore, the first adhesive members are not intentionally arranged on the edge portion of the solar panel 100 on the downstream side in the water gradient direction. This allows water that forms on the back surface of the solar panel 100 due to condensation or the like to be smoothly discharged to the outside from the edge portion on the downstream side in the water gradient direction. At this time, since each of the second adhesive members 421-426 is arranged in parallel with the water gradient direction, they play a role in guiding water flowing from the above-water side to the below-water side in the water gradient direction to the outside without impeding its flow.

[0068] (Example of panel installation construction 2) FIG. 7 is a diagram showing a specific example of the panel installation work of FIG. 2(B). 7 shows a specific example of panel installation work in which a solar panel 100 is installed on an installation object 200, which is a folded-plate roof made by bending metal plate material to form an uneven shape. The example in FIG. 7 differs from the example in FIG. 6 described above in that the contact surface area between the solar panel 100 and the installation object 200 is small, making it difficult to directly adhere the solar panel 100 to the installation object 200. For this reason, support members 501 to 504 are arranged between the solar panel 100 and the installation object 200, as members that support the solar panel 100 and are detachably joined to the installation object 200.

[0069] The support members 501-504 are rod-shaped horizontal bars made of metal or resin and arranged to extend in a direction perpendicular to the water gradient direction of the solar panel 100. Each of the support members 501-504 has a surface 511-514 facing the solar panel 100 and a portion 521-524 facing the installation object 200. Each of the surfaces 511-514 facing the solar panel 100 has a first adhesive member 413-416 arranged thereon, extending in a direction perpendicular to the water gradient direction of the solar panel 100. Therefore, the support members 501-504 are adhered to the solar panel 100 by each of the first adhesive members 413-416.

[0070] Furthermore, each of the portions 521 to 524 facing the installation target 200 is provided with a joining member 531 to 534 for joining each of the support members 501 to 504 to the installation target 200. The joining members 531 to 534 are not particularly limited as long as they are members that can stably join each of the support members 501 to 504 to the installation target 200. For example, they may be members having a fitting portion that fits into each of the support members 501 to 504 and another fitting portion that fits into the installation target 200. Furthermore, for example, they may be members that are joined using metal members such as clamps or fastening metal fittings, hook-and-loop fasteners, weights, or the like.

[0071] 7, it is possible to increase the adhesion area for adhering the solar panel 100. As a result, it is possible to stably install the solar panel 100 on the installation object 200, which is a folded-plate roof.

[0072] (Panel installation example 3) 8(A) and (B) are diagrams showing a specific example of the panel installation work of FIG. 2(C). Fig. 8(A) shows a specific example of panel installation work in which a solar panel 100 is installed on an installation object 200, which is a vinyl greenhouse configured to include a frame portion 211 made of tubular or rod-shaped members and a sheet portion 212 made of a thin resin or the like that covers the entire surface. Fig. 8(B) is a cross-sectional view showing the bb cross section in Fig. 8(A).

[0073] In the installation object 200, the sheet portion 212 is made of a thin resin or the like, whereas the solar panel 100 has a certain weight, so it is difficult to stably adhere the installation object 200. For this reason, support members 601, 602, 603, 604, 605, and 606 that support the solar panel 100 and are detachably joined to the frame portion 211 of the installation object 200 are arranged between the solar panel 100 and the installation object 200.

[0074] The support members 601-606 are made up of rod-shaped members, strip-shaped members, etc. that extend in a direction perpendicular to the water gradient direction of the solar panel 100. In this embodiment, an example will be described in which the support members 601-606 are made up of strip-shaped members. Each of the support members 601-606 has surfaces 611, 612, 613, 614, 615, and 616 that face the solar panel 100. Adhesive members 427, 428, 429, 430, 431, and 432 that extend in a direction perpendicular to the water gradient direction of the solar panel 100 are arranged on the surfaces 611-616 that face the solar panel 100. Therefore, the support members 601-606 are adhered to the solar panel 100 by each of the adhesive members 427-432.

[0075] Furthermore, joining members 631, 632, 633, 634, 635, and 636 are provided on both ends of the support members 601 to 606 to detachably join each of the support members 601 to 606 to the frame portion 211 of the installation object 200. Fig. 8(B) shows the joining member 632 located on the bb cross section of Fig. 8(A). The joining members 631 to 636 are, for example, band adjusters formed integrally with the support members 601 to 606.

[0076] 8, it is possible to increase the adhesion area for adhering the solar panel 100. As a result, the solar panel 100 can be installed stably.

[0077] (Example of panel installation construction 4) FIG. 9 is a diagram showing a specific example of the panel installation work of FIG. 2(D). 9 shows a specific example of panel installation work in which a solar panel 100 is installed on an installation object 200, which is a wall material extending in the water gradient direction. A first adhesive member 412 and second adhesive members 433, 434, 435, 436, 437, 438, 439, 440, and 441 are arranged between the solar panel 100 and the installation object 200 to adhere the solar panel 100 to the installation object 200. It is assumed that a waterproof layer is arranged on the surface of the installation object 200 and that the surface is further painted.

[0078] 9, the first adhesive members 412 are arranged so as to extend in a band-like shape in a direction perpendicular to the water gradient direction at the edge portion on the abovewater side of the solar panel 100 in the water gradient direction. In contrast, no first adhesive members are arranged at the edge portion on the belowwater side of the solar panel 100 in the water gradient direction. In addition, the second adhesive members 433 to 441 are arranged in parallel so as to extend in a band-like shape in the water gradient direction of the solar panel 100.

[0079] Of the second adhesive members 433-441, the second adhesive members 433-438 are made of adhesive. The ends of each of the second adhesive members 433-438 on the above-water side in the water gradient direction are in contact with the first adhesive member 412. Furthermore, of the second adhesive members 433-441, the second adhesive members 439-441 are made of double-sided tape. That is, at least a portion of the second adhesive members is made of double-sided tape. Note that in the example of FIG. 9, the ends of each of the second adhesive members 433-441 on the above-water side in the water gradient direction are not in contact with the first adhesive member 412, but the ends of each of the second adhesive members 433-441 on the above-water side in the water gradient direction may be in contact with the first adhesive member 412.

[0080] Arranging the first adhesive member 412 and the second adhesive members 433 to 441 in the configuration shown in Fig. 9 provides the following effects. That is, the first adhesive member 412 prevents unnecessary gaps from being formed between the edge portion 101 of the solar panel 100 on the water-side in the water gradient direction and the installation object 200. This provides the same effect as the example in Fig. 6 above, that is, prevents rainwater, dust, and the like from penetrating into the back surface of the solar panel 100 (the surface facing the installation object 200). As a result, deterioration of the waterproof layer and paint provided on the surface of the installation object 200 is suppressed.

[0081] Furthermore, each of the second adhesive members 433-441, which are adhesives, prevents unnecessary gaps from forming between the solar panel 100 and the installation object 200 where it is arranged. Furthermore, the first adhesive member is not intentionally arranged on the edge portion of the solar panel 100 on the downstream side in the water gradient direction. This achieves the same effect as the example in FIG. 6 above, that is, water that has formed on the back surface of the solar panel 100 due to condensation or the like can be smoothly discharged to the outside from the edge portion on the downstream side in the water gradient direction. At this time, since each of the second adhesive members 433-441 is arranged in parallel with the water gradient direction, they serve to guide water flowing from the above-water side to the below-water side in the water gradient direction to the outside without impeding the flow.

[0082] Furthermore, each of the second adhesive members 439-441, which are double-sided tapes, prevents unnecessary gaps from being formed between the solar panel 100 and the installation object 200 where it is placed. Furthermore, using the second adhesive members 433-438, which are adhesive, in combination with the second adhesive members 439-441, which are double-sided tapes, provides the following effect: The adhesive strength of the second adhesive members 439-441, which are double-sided tapes, serves as a temporary fix until the second adhesive members 433-438, which are adhesive, hardens, thereby preventing the solar panel 100 from shifting position.

[0083] When adhesive and double-sided tape are used together as adhesive members, the following adhesive member arrangement is realized, taking into account the solar panel installation environment. Specifically, in summer, temperatures are high and the adhesive hardens quickly, whereas in winter, temperatures are low and the adhesive hardens slowly. For this reason, more double-sided tape for temporary attachment is placed in winter than in summer. Furthermore, when the wind speed at the construction site is strong, the adhesive hardens quickly, whereas when the wind speed is weak, the adhesive hardens slowly. Therefore, the number of double-sided tapes for temporary attachment is placed according to the wind speed. Furthermore, the greater the water gradient angle (installation angle) at the installation location of the solar panel, the more susceptible it is to the effects of gravity. Therefore, the number of double-sided tapes for temporary attachment is placed according to the water gradient angle (installation angle) at the installation location of the solar panel. This ensures the necessary strength while eliminating unnecessary materials and construction processes.

[0084] (Examples of construction mode information) 10 to 13 are diagrams showing specific examples of construction mode information output from the solar panel installation support system Sa. As described above, there are various aspects of panel installation work. For this reason, the solar panel installation support system Sa generates and outputs installation aspect information corresponding to the aspect of panel installation work as information for supporting panel installation work.

[0085] 10 shows a specific example of a "bonding line number diagram," which is an example of installation mode information output from the solar panel installation support system Sa. The bonding line number diagram is a diagram that visualizes the calculation results of the number of lines and arrangement positions of adhesive members that bond the solar panel 100 to the installation target object 200.

[0086] The adhesive line number diagram shown in FIG. 10 shows the calculation results of the number of adhesive lines and their placement positions in a panel installation work in which a solar panel 100 having a length of 1840 mm in a direction perpendicular to the water gradient direction is installed on an installation object 200. Specifically, the adhesive line number diagram shows that the adhesive members placed between the solar panel 100 and the installation object 200 are only six lines of second adhesive members (second adhesive members 442, 443, 444, 445, 446, and 447). The adhesive line number diagram also shows that the spacing between adjacent second adhesive members is 360 mm and that the length of the solar panel 100 overhanging the second adhesive members placed at both ends (second adhesive members 441 and 446) is 50 mm. From the adhesive line number diagram shown in FIG. 10, an installer can visually grasp the number of adhesive lines and their placement in the panel installation work.

[0087] 11 shows a specific example of an "adhesive line number matrix table," which is an example of installation mode information output from the solar panel installation support system Sa. The adhesive line number matrix table visualizes the correlation between the number of lines (number of adhesive surface indications) of adhesive members that adhere solar panels to the installation object and the water gradient angle (installation angle).

[0088] The matrix table of the number of adhesive lines shown in Figure 11 shows the correlation between the number of adhesive lines (number of adhesive surface indications) of adhesive members to be placed when installing solar panels on an installation object, which is a folded-plate roof, and the water gradient angle (installation angle). In the example of Figure 11, the height from the ground surface of the location where the solar panels will be installed is assumed to be 10 m. The numerical values ​​shown in the matrix table of the number of adhesive lines are the adhesive stress intensity (N / mm) for each width (adhesive width) of the second adhesive member (15 mm, 20 mm, 25 mm, 30 mm). 2 Furthermore, a pass standard is set in advance for the adhesive stress level, and a value that does not meet the pass standard is displayed in a manner that indicates this.

[0089] For example, when the short side of the solar panel is the water gradient direction and the water gradient angle (installation angle) is 0° (horizontal placement, installation angle 0°), the adhesive stress (N / mm 2 ) is as follows: In other words, when the number of lines of the adhesive member (number of adhesive surface indications) is 6, the adhesive stress level when the width of the line of the adhesive member (adhesion width) is 15 mm is 0.13 (N / mm 2 ), and when the width of the adhesive line (adhesion width) is 20 mm, the adhesive stress is 0.10 (N / mm 2 ) and the adhesive stress when the adhesive line width (adhesion width) is 25 mm is 0.08 (N / mm 2 ), and the adhesive stress when the adhesive width of the adhesive material is 30 mm is 0.07 (N / mm 2 )

[0090] Here, the adhesive stress level when the adhesive member line width (adhesion width) is 15 mm does not meet the pass criteria, so it is displayed in a display mode (color) to indicate this. This allows the installer to understand at a glance that the adhesive widths of the second adhesive member that meet the pass criteria when the number of lines of the adhesive member (number of adhesive surface indications) is 6 are 20 mm, 25 mm, and 30 mm. Note that the adhesive stress level (N / mm 2 A specific example of this is shown in FIG.

[0091] 12 shows a specific example of a "flat roof snow load resistance map," which is an example of construction mode information output from the solar panel installation support system Sa. The flat roof snow load resistance map is a diagram that visualizes the calculation results of the allowable height of snow in the vertical direction when a waterproof layer 300 is placed between a flat roof (concrete frame) as the installation object 200 and the solar panel 100.

[0092] The flat roof snow load resistance diagram shown in Figure 12 shows the relationship between the thickness of the steps d1 and d2 formed by the overlapping portions of the waterproof layer 300 and the thickness of the adhesive member 400 that bonds the solar panel 100 to the installation object 200 via the waterproof layer 300. Specifically, the flat roof snow load resistance diagram shows that the allowable range for the thickness of the steps d1 and d2 formed by the overlapping portions of the waterproof layer 300 is 5 mm or less. The flat roof snow load resistance diagram also shows that the amount of snow that the solar panel 100 can tolerate (allowable snow load height) is 200 cm or less.

[0093] In the example of Figure 12, if the adhesive member 400 can fill the gaps d1 and d2 formed by the overlapping portions of the waterproof layer 300, it is determined that the solar panel 100 can be installed. On the other hand, if the gaps cannot be filled with the adhesive member 400, it is determined that the solar panel 100 cannot be installed. In other words, there is an allowable limit to the thickness of the gaps d1 and d2 formed by the overlapping portions of the waterproof layer 300. For this reason, if the adhesive member 400 cannot fill the gaps d1 and d2 formed by the overlapping portions of the waterproof layer 300, methods such as installing the panel while avoiding those portions or grinding down the installation target object 200 to absorb the thickness of the gaps d1 and d2 may be considered.

[0094] 13 shows a specific example of a "folded-plate roof snow load resistance diagram," which is an example of construction mode information output from the solar panel installation support system Sa. The folded-plate roof snow load resistance diagram is a diagram that visualizes the calculation results of the allowable snow load (allowable snow load height) when the solar panel 100 is directly bonded to a folded-plate roof as the installation object 200.

[0095] The folded-plate roof snow load resistance diagram shown in Figure 13 shows the calculation results of the allowable snow load (allowable snow load height) when a flexible solar panel 100 having flexibility is directly bonded to a folded-plate roof as the installation object 200 with an adhesive member. Specifically, it shows that the allowable snow load (allowable snow load height) is 60 cm or less. From the folded-plate roof snow load resistance diagram shown in Figure 13, the installer can select an installation location taking into account the allowable range of damage to the solar panel 100 due to snow load.

[0096] Fig. 14 is a diagram showing a specific example of panel installation work in which solar panels 100 are installed on a horizontal seam folded-plate roof as the installation object. Figs. 15(A) and (B) are diagrams showing the adhesive form of solar panels 100 and the like installed on a horizontal seam folded-plate roof. Figs. 15(A) and (B) omit illustration of a wiring cover 450 (described below). Note that in Figs. 14 and 15(A) and (B), components and the like equivalent to those in the embodiment of Fig. 6 (flat roof) previously described are given the same reference numerals, and duplicate explanations will be omitted.

[0097] Figure 14 shows a specific example of panel installation work in which solar panels 100 are installed on an installation object 200, which is a horizontal seam folded-plate roof with a water gradient. As shown in Figure 15(A), the horizontal seam folded-plate roof of this embodiment is configured so that the flat portion becomes lower in a stepped manner from the above-water side to the below-water side in the water gradient direction. Also, as shown in Figure 14, six solar panels 100 are arranged horizontally so that their short sides are in the water gradient direction.

[0098] 14, a first adhesive member 411 and second adhesive members 421, 422, 423, 424, and 425 for adhering the solar panel 100 to the installation object 200 are arranged between the solar panel 100 and the installation object 200. In the example of FIG. 14, the first adhesive member 411 is arranged at the far end of the solar panel 100 on the abovewater side in the water gradient direction, so as to extend in a strip-like shape in a direction perpendicular to the water gradient direction. Similarly to the first adhesive member 411, the second adhesive members 421 to 425 are arranged so as to extend in a strip-like shape in a direction perpendicular to the water gradient direction of the solar panel 100. Specifically, the second adhesive members 421 to 425 are arranged parallel to the edge portions of the step portions where the metal plates are overlapped.

[0099] Of the second adhesive members 421 to 425, second adhesive members 421 and 424 are partially made up of double-sided tape. That is, in second adhesive members 421 and 424, the portions shown in white are made up of double-sided tape, and the portions shown in black are made up of adhesive. Note that the configuration including double-sided tape in part is not limited to second adhesive members 421 and 424, and may be other second adhesive members. Furthermore, in second adhesive members 421 and 424, the range, position, number, etc. of the double-sided tape to be arranged are not limited to the example shown in the figure, and can be set appropriately depending on the size of solar panel 100 to be installed, installation conditions, etc.

[0100] As shown in FIG. 15(A), each adhesive member is placed on the upper part of the step where the metal plates are stacked together (hereinafter also referred to as the "step upper part 201") or on the abovewater end (not shown). Note that, on the belowwater side, if the solar panel 100 overhangs more than 50 mm, it is desirable to apply adhesive. Also, at the abovewater and belowwater ends, the adhesive (second adhesive member) may not be applied to the step upper part 201, which increases the gap between the solar panel 100 and the surface of the installation object 200. In this way, when the gap between the solar panel 100 and the surface of the installation object 200 is large, it is desirable to apply a large amount of adhesive, as with the first adhesive member 411 shown in FIG. 15(A), to prevent a gap from forming between the solar panel 100 and the surface of the installation object 200.

[0101] As shown in Fig. 14, wiring covers 450 are arranged around the solar panels 100 that are arranged horizontally in two columns and three rows. The wiring covers 450 are members that cover cables 455, junction boxes 456, connectors 457, etc. (see Fig. 15(A)) that are drawn out from the solar panels 100. The wiring covers 450 are fixed to the installation object 200 with adhesive or tapping screws. In this embodiment, the wiring covers 450 that are arranged along the water gradient direction are divided into multiple pieces.

[0102] The above-water side portion of the wiring cover 450 shown in FIG. 15(B) is coated with adhesive 451 continuously over the entire area. This configuration makes it possible to prevent water from entering the inside of the wiring cover 450. Furthermore, the below-water side portion of the wiring cover 450 is coated with adhesive 451 intermittently. This configuration makes it possible to smoothly drain water that has entered the wiring cover 450 to the outside. Note that components such as the junction box 456 and connector 457 are fixed to the edge portion of the solar panel 100 with adhesive.

[0103] 14, the following effects are achieved. That is, the first adhesive member 411 prevents unnecessary gaps from being formed between the above-water edge of the solar panel 100 in the water gradient direction and the installation object 200. This prevents rainwater, dust, and the like from penetrating into the back surface of the solar panel 100 (the surface facing the installation object 200). As a result, deterioration of the waterproof layer and paint provided on the surface of the installation object 200 is suppressed.

[0104] Additionally, each of the second adhesive members 421-426 prevents unnecessary gaps from forming between the solar panel 100 and the installation target 200 where the second adhesive member is located. Furthermore, because a portion of the second adhesive member is made of double-sided tape, the adhesive can be applied over a wider area while still providing a temporary hold until the adhesive hardens. In particular, because horizontal seam folded-plate roofs often have a relatively large inclination angle, temporary hold with double-sided tape is essential. Therefore, by extending the length of the double-sided tape depending on the inclination angle of the folded-plate roof, it is possible to reduce unnecessary materials and construction processes while ensuring the adhesive strength required to secure the solar panel 100. Furthermore, according to the configuration of this embodiment, the double-sided tape is positioned in the same line as the adhesive, which more effectively prevents misalignment of the solar panel 100 compared to a configuration in which the double-sided tape is positioned separately from the adhesive.

[0105] FIG. 16 is a diagram showing a first construction mode for preventing scattering of a solar panel 100 installed on an installation object 200. This embodiment will be described using as an example the prevention of scattering of a solar panel 100 installed on an installation object 200 that is a wall material extending in the water gradient direction, as in FIG. 9 (wall material). In FIG. 16 and FIG. 17 described later, the same members as those in the embodiment of FIG. 9 are given the same reference numerals, and duplicated explanations will be omitted. Although not shown, it is assumed that a first adhesive member 412 and second adhesive members 433 to 441 (see FIG. 9) are arranged between the solar panel 100 shown in FIG. 16 and the installation object 200.

[0106] As shown in Fig. 16, the solar panel 100 has a plurality of through holes 460 formed along the water gradient direction (vertical direction) on the left and right edge portions. The total number of through holes 460 on the left and right sides is, for example, about 8 to 12. Fig. 16 shows an example in which a total of 12 through holes 460 are formed on the left and right sides. A screw 461 is inserted into each of the through holes 460 formed in the solar panel 100, and the solar panel 100 is fixed to the wall material that is the installation object 200 by screwing.

[0107] According to the first construction mode described above, the left and right edge portions of the solar panel 100 are fixed to the wall material with screws 461. Therefore, in cases where the solar panel 100 is subjected to wind pressure that exceeds expectations, or where the adhesive strength of the adhesive decreases more quickly than expected, etc., it is possible to prevent the solar panel 100 from peeling off from the installation object 200 and scattering. Note that in Fig. 14, the positions where the solar panel 100 is fixed with the screws 461, etc. are not limited to the example shown in the figure.

[0108] Fig. 17 is a diagram showing a second construction mode for preventing scattering of a solar panel 100 installed on an installation object 200. This embodiment will also be described using as an example the prevention of scattering of a solar panel 100 installed on an installation object 200 that is a wall material extending in the water gradient direction, as in Fig. 9 (wall material).

[0109] In FIG. 17, a plurality of through holes (not shown) are provided in the left and right edge portions of the solar panel 100 along the water gradient direction (vertical direction). The total number of through holes is, for example, about 8 to 12 on the left and right sides. FIG. 17 shows an example in which a total of 12 through holes are provided on the left and right sides. As shown in the partially enlarged view of FIG. 17, an eye nut 471 is attached to each of the through holes provided in the solar panel 100. The eye nut 471 is a component in which a base and a ring are integrated. A female screw is provided on the back side of the base. The eye nut 471 is fixed by a bolt (not shown) inserted into the through hole from the back side of the solar panel 100.

[0110] Furthermore, the installation object 200 is provided with a plurality of fastenings 472. The fastenings 472 are components for fixing wires 473 (described below) and are formed in a substantially L-shape. A pair of fastenings 472 are provided on the abovewater side and belowwater side in the water gradient direction, with the solar panel 100 sandwiched between them. Each fastening 472 is arranged so as to substantially coincide with the position of each through-hole provided on the left and right sides of the solar panel 100 on the abovewater side and belowwater side in the water gradient direction.

[0111] A wire 473 is stretched between a pair of fasteners 472 arranged on the abovewater and belowwater sides of the solar panel 100 in the water gradient direction, passing through the rings of each eye nut 471. The wire 473 is a long, thin, linear member made of metal. One end of the wire 473 is fixed to the fastener 472 arranged on the abovewater side of the solar panel 100 in the water gradient direction. Meanwhile, the other end of the wire 473 is fixed to the fastener 472 arranged on the belowwater side of the solar panel 100 in the water gradient direction.

[0112] In the second installation form described above, the solar panel 100 is fixed to the wall material by a plurality of eye nuts 471 provided at the far left and right ends, a wire 473 provided to pass through the ring of each eye nut 471, and fasteners 472 that secure both ends of the wire 473. Therefore, if the solar panel 100 is subjected to wind pressure that exceeds expectations, or if the adhesive strength of the adhesive decreases more quickly than expected, it is possible to prevent the solar panel 100 from peeling off from the installation object 200 and scattering.

[0113] In the second construction mode, instead of metal wires, linear members made of composite materials including resin, carbon fiber, etc. may be used. Also, while Fig. 17 shows a configuration in which a pair of fasteners 472 are provided on the above-water side and below-water side of two solar panels 100 in the water gradient direction, this is not limiting. A pair of fasteners 472 may also be provided on the above-water side and below-water side of one solar panel 100 in the water gradient direction.

[0114] [Management Server 1 processing flow] Next, we will explain the process flow in which the management server 1 calculates the adhesive stress level on the installation object based on the generated adhesive area and sends the judgment result of whether the adhesive stress level is within the allowable range of the adhesive to the installer terminal 2.

[0115] FIG. 18 is a flowchart showing an example of the flow of a process in which the management server 1 transmits the determination result of the adhesive stress level of the adhesive member to the installer terminal 2.

[0116] When the management server 1 receives an instruction from the installer terminal 2 to automatically calculate the adhesive stress level of the adhesive (START), the management server 1 acquires installation condition information relating to the installation conditions of the solar panel from the installation condition DB 42 (step S11).

[0117] The management server 1 calculates the design load value for the solar panel 100 after installation based on the acquired installation condition information (step S12). The management server 1 extracts a predetermined set adhesion area from the acquired installation condition information (step S13).

[0118] The management server 1 calculates the adhesive stress intensity of the adhesive to the installation object 200 based on the extracted set adhesive area and the design load value calculated in step S12 (step S14). The management server 1 determines whether the calculated adhesive stress intensity is within the range of the allowable value (step S15).

[0119] The management server 1 stores the calculation results of the design load value, adhesive stress level, etc. in a predetermined area of ​​the construction condition DB 42, and transmits the judgment result of the calculated adhesive stress level (including an explanation of the judgment process) to the contractor terminal 2 (step S16). This ends the processing of the management server 1 (END).

[0120] The management server 1 outputs the judgment result "OK" if the calculated values ​​of each item, i.e., wind pressure load during a storm, snow load during snowfall, and seismic load during an earthquake, are all within the allowable range (allowable stress). On the other hand, the management server 1 outputs the judgment result "NG" if any of the calculated values ​​of the above items are outside the allowable range.

[0121] If the judgment result is "NG," the installer adjusts the set adhesive area included in the installation condition information (generates new installation mode information) and issues a command to automatically calculate the adhesive stress of the adhesive from the installer terminal 2. The management server 1 then calculates the adhesive stress of the adhesive to the installation object based on the adjusted set adhesive area extracted from the installation condition information and the calculated design load value. In this way, if the judgment result indicates that the calculated adhesive stress is outside the allowable range, the installer can efficiently obtain a sufficient adhesive area for installing solar panels by repeating the process of adjusting the set adhesive area and having the system recalculate the adhesive stress.

[0122] If the judgment result is "NG," the management server 1 may automatically adjust the set adhesive area and recalculate the adhesive stress of the adhesive. The adjustment range of the set adhesive area may be a value preset by the installer, or may be automatically set by the management server 1 based on the difference between the calculated value that resulted in NG and the allowable value. For example, the management server 1 sets the adjustment range of the set adhesive area so that it increases the larger the difference between the calculated value and the allowable value, and decreases the adjustment range of the set adhesive area so that it decreases the smaller the difference between the calculated value and the allowable value.

[0123] Furthermore, in addition to calculating the adhesive stress of the adhesive to the installation target, the management server 1 may also calculate the resistance of the roofing material to wind, snow, earthquake loads, the weight of the packaging pallet, and the weight of the worker when the solar panels are lifted onto the roof together with their packaging materials and installation work is carried out. In other words, by calculating the compressive stress, bending stress, and shear stress of the roofing material and comparing them with the allowable values, the safety of the roofing material on which the solar panels are installed can be appropriately determined.

[0124] <Advantageous Effects of the Present Embodiment> According to the configurations shown in Figs. 6, 7 and 9 described above, water generated on the rear surface of the solar panel due to condensation or the like can be discharged to the outside from the edge portion on the lower side of the water in the direction of the water gradient. Furthermore, as shown in FIG. 10, the solar panel installation support system Sa calculates information such as the number of adhesive lines, the spacing between lines, and the width of the lines according to the specifications of the solar panel 100. As a result, it is possible to ensure the necessary strength while eliminating unnecessary materials and construction processes. Furthermore, the calculation results of the number of adhesive lines, the spacing between lines, and the width of the lines calculated by the solar panel installation support system Sa can be used in preparing application documents for various application procedures. As a result, it is possible to shorten the time required to prepare application documents and improve the accuracy of the content of the application documents.

[0125] Furthermore, as shown in Figures 11 to 13, for uneven roofing and wall materials such as folded-plate roofs that are prone to peeling from solar panels, information such as the number of lines of the adhesive material, the spacing between lines, and the width of the lines is calculated based on information about the rigidity of the solar panel support member and information about the flexibility of the solar panel. This makes it possible to ensure the necessary strength while eliminating unnecessary materials and construction processes. As a result, a sufficient adhesive area for installing solar panels can be secured. Furthermore, a sufficient adhesive area for installing solar panels can be secured for greenhouses and other structures where it is difficult to secure a surface for direct adhesion. As a result, the workload of installers installing solar panels can be reduced.

[0126] Furthermore, the solar panel installation support system Sa determines whether a set adhesive area is appropriate based on the adhesive stress of the adhesive applied to the installation object over the set adhesive area, making it possible to quickly and accurately obtain the adhesive area required to install a solar panel. Therefore, the solar panel installation support system Sa can reduce the workload of installers who install solar panels. Furthermore, the solar panel installation support system Sa can use the results of the calculated adhesive stress (including an explanation of the determination process) to prepare application documents for various application procedures. As a result, the time required for installers to prepare application documents can be shortened and the accuracy of the content of the application documents can be improved.

For example, the "Adhesive Line Number Matrix Table" shown in FIG. 11 above shows the adhesive stress level when the solar panel 100 is placed horizontally so that the short side direction is in the water gradient direction, but this is not limiting. It is also possible to show the adhesive stress level when the solar panel 100 is placed vertically so that the long side direction is in the water gradient direction.
