Description

[Technical Field]

[0001] The present invention relates to an information processing system, a photovoltaic power generation device installation support system, a program, and a determination method. [Background technology]

[0002] There are building owners who want to reduce electricity bills and CO2 emissions by installing solar power generation equipment on the roofs of existing buildings. It is also effective for sellers and leasers of solar power generation equipment to appeal to building owners about the effects of reducing electricity bills and CO2 emissions.

[0003] A technology has been devised to propose the installation of a solar power generation system (see, for example, Patent Document 1). Patent Document 1 discloses the configuration of a contract support server that calculates the expected amount of electricity sold by a solar power generation system on the roof or rooftop of a rental building and calculates the eco-contribution of power generation. Summary of the Invention [Problem to be solved by the invention]

[0004] However, with conventional technology, when the remaining years of a building's statutory useful life are short, it is difficult to determine whether or not a solar power generation system can be installed on the premise of investment recovery through long-term operation. In other words, when the remaining years of an existing building's statutory useful life are short, even if it is thought from experience that the building can actually be used continuously beyond the statutory useful life, it is not easy to determine whether or not a solar power generation system can be installed on the existing building while continuing to use it based on the building's physical strength.

[0005] In view of the above-mentioned problems, an object of the present invention is to provide a technique for assisting in determining whether or not a photovoltaic power generation device can be installed on a building. [Means for solving the problem]

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An information processing system and a determination method performed by the information processing system will be described below as an example of an embodiment of the present invention with reference to the accompanying drawings.

[0010] <Outline of solar power generation equipment installation considerations> Many building owners want to install solar power generation equipment on the roofs of their old existing buildings to reduce electricity bills and CO2 emissions. However, if the existing building is old, the possibility of recouping the investment is low even if solar power generation equipment is installed, so there are quite a few cases where building owners give up or solar power generation companies turn them down.

[0011] In addition, there are many cases where the building owner decides to install solar power generation equipment even if the existing building is old, and solar power generation companies have already installed it. However, since there is no technical basis for the possibility of recovering the investment, the results of the investment cannot be determined until several years have passed. If the building owner's outlook is inappropriate, there is a risk that the investment will not be recovered.

[0012] Therefore, the photovoltaic power generation system installation support system of this embodiment provides the following support when considering installing a photovoltaic power generation system in an existing building with a short remaining legal useful life (hereinafter referred to as remaining legal useful life).

[0013] The photovoltaic power generation device installation support system of this embodiment technically evaluates the remaining years of the physical useful life of an existing building (hereinafter referred to as the remaining physical useful life) and supports the decision on whether or not to install a photovoltaic power generation facility. In other words, when a building owner or the like is considering installing a photovoltaic power generation device on the roof or the like of an old building, the photovoltaic power generation device installation support system can make an installation decision based on technical grounds.

[0014] Furthermore, in this embodiment, the photovoltaic power generation system installation support system can present property insurance and its premiums that can be taken out for the photovoltaic power generation system based on the physical useful life and building strength of the existing building. Being able to take out property insurance for the photovoltaic power generation system based on the remaining physical useful life and building strength of the existing building means that the insurance company has recognized that there is a rational basis for installing the photovoltaic power generation system on the existing building. In other words, having property insurance for the photovoltaic power generation system based on the remaining physical useful life and building strength of the existing building means that there is a low probability that the installed photovoltaic power generation system will become unusable due to the remaining statutory useful life of the existing building. Therefore, by determining whether or not property insurance is available for the photovoltaic power generation system based on the remaining physical useful life and building strength of the existing building, the photovoltaic power generation system installation support system can determine whether or not it is acceptable to install the photovoltaic power generation system based on the rational basis provided by the insurance company.

[0015] FIG. 1 is a diagram for explaining an outline of the determination of whether or not a solar power generation device can be installed. (1) First, the user inputs the remaining legal useful life, remaining physical useful life, etc. of the existing building into the terminal device 30. The user may simply input the identification information of the existing building. (2) The input content is sent to the information processing system 10. The information processing system 10 first determines whether the remaining statutory useful life is equal to or greater than the operation period of the solar power generation device. If the remaining statutory useful life is shorter than the operation period of the solar power generation device, the information processing system 10 then determines whether the remaining physical useful life is equal to or greater than the operation period. If the remaining physical useful life is equal to or greater than the operation period, the information processing system 10 determines that the solar power generation device can be installed.

[0016] If the remaining physical useful life is equal to or greater than the operation period, the information processing system 10 determines whether or not there is property insurance available for the photovoltaic power generation system based on the remaining physical useful life and building strength of the existing building. If there is property insurance available, the information processing system 10 generates a list of property insurance policies indicating that it has been determined that the photovoltaic power generation system can be installed, and returns the list to the terminal device 30. (3) The terminal device 30 displays a list of non-life insurance, allowing the user to install a solar power generation system with peace of mind knowing that the insurance is based on technical and rational grounds.

[0017] <Terminology> A photovoltaic power generation system is a device that converts solar light energy into electricity. A photovoltaic power generation system includes, for example, solar panels and a power conditioner. Although the solar panels are installed on the roof, in this embodiment, the term "photovoltaic power generation system" is used without making any distinction.

[0018] A building generally refers to a structure that is constructed for people to live in, store things in, or work in. The Real Estate Registration Act defines a building as "a structure that has a roof and surrounding walls or similar, is fixed to land, and is in a state that allows it to be used for its intended purpose." In this embodiment, the building may be any structure that can be equipped with a solar power generation system. An existing building is a building that has been in use for a certain period of time.

[0019] The legal useful life is the period set by the government during which a fixed asset can be used. The legal useful life is used, for example, to calculate depreciation expenses, and it is rare for a building to become unusable even after the legal useful life has passed.

[0020] The physical useful life is the period during which a building's designed fixed assets can be used, or the period during which fixed assets can be used calculated from the design drawings.

[0021] The data on a building may be data that can identify at least one of the remaining statutory useful life or building strength of the building. The data on a building may include the remaining statutory useful life or building strength, or the remaining statutory useful life or building strength may be identified by the building's identification information.

[0022] <System configuration example> 2 is an example of a system configuration diagram of a photovoltaic power generation device installation support system 100. The photovoltaic power generation device installation support system 100 includes an information processing system 10, a building data storage device 51, a non-life insurance data storage device 52, a photovoltaic power generation device data storage device 53, and a terminal device 30. However, the terminal device 30 may be a general-purpose computer and may not be included in the photovoltaic power generation device installation support system 100. Furthermore, as a system configuration, the building data storage device 51, the non-life insurance data storage device 52, and the photovoltaic power generation device data storage device 53 may be simple storages, and therefore the photovoltaic power generation device installation support system 100 described in this embodiment only needs to include at least the information processing system 10.

[0023] The information processing system 10 and the terminal device 30 are communicably connected via a wide area network N1 such as the Internet. Furthermore, the information processing system 10 and the terminal device 30 can communicate with a building data storage device 51, a non-life insurance data storage device 52, and a solar power generation device data storage device 53 via the network N1. The information processing system 10 can communicate with the building data storage device 51, the non-life insurance data storage device 52, and the solar power generation device data storage device 53 using, for example, an API (Application Programming Interface).

[0024] The information processing system 10, the building data storage device 51, the non-life insurance data storage device 52, and the solar power generation device data storage device 53 may be installed in the cloud, a data center, or on-premise. The building data storage device 51, the non-life insurance data storage device 52, and the solar power generation device data storage device 53 may be, for example, a data server or a NAS (Network Attached Storage). Furthermore, the information processing system 10 may be a web server that returns to the terminal device 30, in response to a request from the terminal device 30, a determination result as to whether or not it is acceptable to install a solar power generation device.

[0025] The information processing system 10 determines that a solar power generation system can be installed if the remaining statutory useful life or remaining physical useful life of an existing building is equal to or longer than the operation period of the solar power generation system, based on the building data storage device 51, the property insurance data storage device 52, and the solar power generation system data storage device 53. Furthermore, the information processing system 10 further determines whether there is a rational basis for installing a solar power generation system on an existing building based on whether or not there is property insurance for the solar power generation system to be installed on the existing building.

[0026] The information processing system 10 may have one or more of a building data storage device 51, a non-life insurance data storage device 52, and a solar power generation device data storage device 53. In addition, two or more of the building data storage device 51, the non-life insurance data storage device 52, and the solar power generation device data storage device 53 may be integrated.

[0027] The information processing system 10 may be a web server that determines whether a solar power generation system can be installed in an existing building in response to a request from a terminal device 30. A server is a computer or software that provides information and processing results in response to a request from a client.

[0028] The information processing system 10 may be compatible with cloud computing. Cloud computing refers to a usage mode in which resources on a network are used without regard to specific hardware resources. Therefore, the information processing system 10 does not need to be housed in a single housing or provided as a single integrated device. The functions of the information processing system 10 may be distributed among multiple information processing devices, or multiple information processing devices may each have all of the functions and the information processing device that processes the information may be switched by load balancing or the like.

[0029] The terminal device 30 is installed in a facility such as a company or a factory, and is connected to a network N2. The network N2 may be a LAN, Wi-Fi (registered trademark), wide area Ethernet (registered trademark), a mobile phone network such as 4G, 5G, or 6G, or the like.

[0030] The terminal device 30 is a general-purpose computer used by a user. Here, the user is a person who uses the information processing system 10 (a person who determines whether a solar power generation system can be installed in an existing building). The person who uses the information processing system 10 may be a power generation company, a seller of a solar power generation system (including a leaser), an owner of an existing building, an employee of an insurance company, or any other person who wants to determine whether a solar power generation system can be installed in an existing building.

[0031] The users also include those who manage the building data storage device 51, the non-life insurance data storage device 52, and the solar power generation device data storage device 53. The data managers operate the terminal device 30 to register and edit building data, non-life insurance data, and solar power generation device data in the building data storage device 51, the non-life insurance data storage device 52, and the solar power generation device data storage device 53.

[0032] In the following description, a user refers to a person who uses the information processing system 10, but the person who manages the data may also be a person who uses the information processing system 10.

[0033] A web browser and a native application dedicated to the information processing system 10 run on the terminal device 30. The terminal device 30 and the information processing system 10 execute a web application. A web application is an application that runs through cooperation between a program written in a programming language (for example, JavaScript (registered trademark)) that runs on the web browser and a program on the web server (information processing system 10) side. In contrast, an application that cannot be executed unless it is installed on the terminal device 30 is called a native application. In this embodiment, the application executed on the terminal device 30 may be a web application or a native application.

[0034] The terminal device 30 may be, for example, a desktop PC, a notebook PC, a smartphone, a PDA (Personal Digital Assistant), a tablet terminal, etc. used by a user. Alternatively, the terminal device 30 may be any device on which a web browser or a native application runs. The terminal device 30 may also be an image processing device, an image forming device, an MFP (Multifunction Peripheral), a digital camera, a projector, an electronic whiteboard, a video conference terminal, etc.

[0035] In addition, in this embodiment, the information processing system 10 is described as determining whether a solar power generation device can be installed in an existing building, but the terminal device 30 may determine whether a solar power generation device can be installed in an existing building. Alternatively, the building data storage device 51, the non-life insurance data storage device 52, or the solar power generation device data storage device 53 may make the determination.

[0036] The building data storage device 51 stores data such as the statutory useful life, physical useful life, and building strength of the existing building on which the solar power generation device is installed (hereinafter, the data stored in the building data storage device 51 may be referred to as building data). The building data storage device 51 may be an information processing device such as a data server, a NAS (Network Attached Storage), or a storage such as an HDD.

[0037] The non-life insurance data storage device 52 stores data related to non-life insurance for solar power generation equipment installed in existing buildings (hereinafter, the data stored in the non-life insurance data storage device 52 may be referred to as non-life insurance data). The non-life insurance data storage device 52 may be an information processing device such as a data server, a NAS, or a storage device such as an HDD.

[0038] The photovoltaic power generation device data storage device 53 stores data related to candidates for photovoltaic power generation devices to be installed in existing buildings (hereinafter, the data stored in the photovoltaic power generation device data storage device 53 may be referred to as photovoltaic power generation device data). The photovoltaic power generation device data storage device 53 may be an information processing device such as a data server, a NAS, or a storage such as an HDD.

[0039] <Hardware configuration example> The hardware configuration of the photovoltaic power generation device installation support system 100 will be described with reference to Fig. 3. Fig. 3 is a diagram showing an example of the hardware configuration of the information processing system 10, the terminal device 30, the building data storage device 51, the non-life insurance data storage device 52, and the photovoltaic power generation device data storage device 53. As shown in Fig. 3, the information processing system 10 and the terminal device 30 are constructed by a computer 500, and include a CPU 501, a ROM 502, a RAM 503, an HD (Hard Disk) 504, an HDD (Hard Disk Drive) controller 505, a display 506, an external device connection I / F (Interface) 508, a network I / F 509, a bus line 510, a keyboard 511, a pointing device 512, an optical drive 514, and a media I / F 516.

[0040] Of these, the CPU 501 controls the overall operations of the information processing system 10 and the terminal device 30. The ROM 502 stores programs such as IPL used to drive the CPU 501. The RAM 503 is used as a work area for the CPU 501.

[0041] The HD 504 stores various data such as programs, etc. The HDD controller 505 controls reading and writing of various data from and to the HD 504 under the control of the CPU 501.

[0042] The display 506 displays various types of information such as a cursor, menus, windows, characters, or images. The external device connection I / F 508 is an interface for connecting various types of external devices. In this case, the external devices are, for example, USB (Universal Serial Bus) memory, printers, etc.

[0043] The network I / F 509 is an interface for data communication using the network N2. The bus line 510 is an address bus, a data bus, or the like for electrically connecting the components such as the CPU 501 shown in FIG.

[0044] The keyboard 511 is a type of input means having multiple keys used to input characters, numbers, various instructions, etc. The pointing device 512 is a type of input means used to select and execute various instructions, select a processing target, move a cursor, etc.

[0045] The optical drive 514 controls reading and writing of various data from and to an optical storage medium, which is an example of a removable storage medium. The optical storage medium may be, for example, a CD, a DVD, or Blu-ray (registered trademark). The media I / F 516 controls reading and writing (storing) of data from and to a storage medium 515, such as a flash memory.

[0046] <About the function> Next, a functional configuration of the photovoltaic power generation device installation support system 100 according to this embodiment will be described with reference to Fig. 4. Fig. 4 is a diagram showing the functional configuration of an example of the photovoltaic power generation device installation support system 100 according to this embodiment.

[0047] <<Terminal Device>> The terminal device 30 has a communication unit 31, a display control unit 32, and an operation reception unit 33. Each of these functional units is a function or means realized by the CPU 501 shown in Fig. 3 executing instructions contained in one or more programs installed in the terminal device 30. The programs may be a web browser or a native application.

[0048] The communication unit 31 (an example of a first communication unit) transmits and receives various information to and from the information processing system 10. In this embodiment, the communication unit 31 receives screen information such as a solar power generation device search screen from the information processing system 10, and transmits a solar power generation device search request, etc. to the information processing system 10.

[0049] The display control unit 32 interprets screen information of various screens and displays it on the display 506. The operation accepting unit 33 accepts various operations on the various screens displayed on the display 506 by the user.

[0050] <<Information Processing System>> The information processing system 10 has a communication unit 11, a screen generation unit 12, a statutory useful life determination unit 13, a physical useful life determination unit 14, an insurance determination unit 15, a building strength determination unit 16, and a photovoltaic power generation device determination unit 17. Each functional unit of the information processing system 10 is a function or means realized by the CPU 501 shown in FIG. 3 executing instructions contained in one or more programs installed in the information processing system 10.

[0051] The communication unit 11 (an example of a second communication unit) transmits and receives various information to and from the terminal device 30. In this embodiment, the communication unit 11 transmits screen information such as a solar power generation device search screen to the terminal device 30, and receives a solar power generation device search request and the like from the terminal device 30. The communication unit 11 also communicates with the building data storage device 51, the non-life insurance data storage device 52, and the solar power generation device data storage device 53, and receives the data stored therein.

[0052] The screen generator 12 generates screen information for displaying a web application screen on the terminal device 30. The screen information is a program written in HTML, XML, a scripting language, CSS (Cascading Style Sheet), etc. The structure of a web page is mainly specified by HTML, the behavior of the web page is defined by the scripting language, and the style of the web page is specified by CSS.

[0053] The legal useful life determination unit 13 determines whether the remaining legal useful life of the existing building specified by the user is equal to or longer than the operation period of the solar power generation device. If this condition is met, it is determined that the solar power generation device can be installed in the existing building from the viewpoint of the legal useful life.

[0054] If the remaining statutory useful life of the existing building is not equal to or greater than the operation period of the solar power generation device, the physical useful life determination unit 14 determines whether the remaining physical useful life of the existing building specified by the user is equal to or greater than the operation period of the solar power generation device. If this condition is met, it is determined that the solar power generation device may be installed in the existing building from the viewpoint of the remaining physical useful life.

[0055] The insurance determination unit 15 determines whether or not there is property insurance available for the solar power generation system based on the remaining physical useful life and building strength of the existing building. The determination by the insurance determination unit 15 that there is property insurance available for the solar power generation system is one of the rational grounds for installing the solar power generation system on the existing building. If there is property insurance available for the solar power generation system based on the remaining physical useful life and building strength of the existing building, the insurance determination unit 15 determines the property insurance to be taken out for the solar power generation system. Furthermore, the insurance determination unit 15 may determine the insurance premium and compensation amount based on the remaining physical useful life and building strength.

[0056] The building strength determination unit 16 determines whether the building strength of the existing building is equal to or greater than the load of the solar power generation system. If this condition is met, it is determined that the solar power generation system can be installed in the existing building from the viewpoint of building strength.

[0057] The photovoltaic power generation system determination unit 17 determines a photovoltaic power generation system that can be installed in an existing building based on the remaining physical useful life of the existing building and the warranty period of the photovoltaic power generation system. For example, if the remaining physical useful life of the existing building is extremely short, it is a risk for the non-life insurance company to take out a property insurance with a long warranty period. Therefore, if the remaining physical useful life of the existing building is equal to or greater than the warranty period of the photovoltaic power generation system, the photovoltaic power generation system determination unit 17 determines that this photovoltaic power generation system is a photovoltaic power generation system that can be installed in the existing building.

[0058] <Building data, property insurance data, solar power generation equipment data> Next, the building data, non-life insurance data, and photovoltaic power generation device data will be described with reference to FIGS.

[0059] <<Building data>> FIG. 5 shows an example of building data stored in the building data storage device 51. The building data storage device 51 stores data on existing buildings on which a solar power generation system can be installed for each existing building. The building data may be a collection of existing information, such as information necessary for real estate transactions. This is because the information necessary for real estate transactions often includes the statutory useful life and physical useful life. Naturally, the person managing the building data may calculate or prepare the building data and register it in the building data storage device 51.

[0060] The statutory useful life item stores the statutory useful life of existing buildings. The statutory useful life is determined by law based on the structure and use (residential or commercial) of the existing building. Structures include wood, reinforced concrete, and steel frame. For example, the statutory useful life of a residential building made of reinforced concrete is 47 years. The statutory useful life of a commercial building made of steel frame is 12 to 38 years, depending on the thickness of the steel frame.

[0061] The physical service life field stores the number of years that an existing building can be safely used, calculated based on its structure. There is a known method for calculating the physical service life from the design drawings of the existing building.

[0062] The building age field stores the number of years that have passed since the completion of the existing building. The remaining legal useful life is the legal useful life minus the building age. The remaining physical useful life is the physical useful life minus the building age.

[0063] The structure item stores the structure of the existing building (wooden, reinforced concrete, steel frame, etc.). The structure is often described in design drawings or in some kind of transaction document.

[0064] The building strength item stores the load-bearing capacity of the existing building. Building strength is calculated using structural calculations determined from the design drawings. Building strength is also listed on building confirmation applications, so it can be confirmed from documents.

[0065] The roof area field stores the roof area of ​​the existing building and the area that can be used to install a solar power generation system. The roof area is either listed on the design drawings or can be measured by the user.

[0066] The roof slope field stores the angle of the roof relative to the horizontal. The roof slope is specified on the architectural drawings. The roof slope may be used in determining property insurance.

[0067] <<Property Insurance Data>> 6 shows an example of non-life insurance data stored in the non-life insurance data storage device 52. The non-life insurance data storage device 52 stores, for each non-life insurance, the conditions for existing buildings to which the non-life insurance can be applied. The non-life insurance may be stored by non-life insurance company.

[0068] The remaining legal useful life item stores the remaining legal useful life of the existing building required for applying the property insurance. For example, the remaining legal useful life may be 20 years.

[0069] The remaining physical useful life item stores the remaining physical useful life of the existing building required for applying the property insurance. For example, the remaining physical useful life may be 20 years.

[0070] The building strength item stores the building strength of the existing building required for the property insurance to be applied. This is because if the building strength does not exceed a certain level, there is a high possibility that the solar power generation equipment will be damaged in a natural disaster.

[0071] The solar cell installation area field stores the roof area of ​​the existing building required for applying the property insurance, because the installation area of ​​the solar power generation equipment that corresponds to each property insurance varies depending on the property insurance.

[0072] The insurance premium per unit area field stores the insurance premium per unit area of ​​the solar power generation system when the property insurance is contracted. The insurance premium per unit area is not necessarily fixed. For example, the insurance premium per unit area may increase or decrease depending on the remaining physical useful life or the strength of the building.

[0073] The unit area compensation amount field stores the amount guaranteed per unit area of ​​the photovoltaic power generation system in the event that the property insurance contract is signed and the photovoltaic panel is damaged. The unit area compensation amount is not necessarily fixed. For example, the unit area compensation amount may increase or decrease depending on the remaining physical useful life and the strength of the building.

[0074] The usable temperature range stores the range of temperatures that the solar power generation device can be used in as insured. This can restrict insurance coverage for solar power generation devices used in unexpectedly low or high temperatures.

[0075] The usable humidity range stores the usable humidity range of the solar power generation equipment assumed by the insurance company. This can restrict the insurance coverage for the solar power generation equipment used in unexpected low or high humidity environments.

[0076] The tilt angle field stores the maximum tilt angle at which a solar power generation system is installed that is assumed by insurance. Since the risk of damage increases when a solar power generation system is installed at a large angle, insurance coverage can be restricted for solar power generation systems that are used at large tilt angles.

[0077] <<Solar power generation equipment data>> 7 shows an example of photovoltaic power generation device data stored in the photovoltaic power generation device data storage device 53. The photovoltaic power generation device data storage device 53 stores data related to the photovoltaic power generation device.

[0078] The price per unit area of ​​the solar panel is stored in the "Panel Price" field. The panel price is one of the indicators that users use when considering purchasing a solar power generation device.

[0079] The panel area field stores the area of ​​the solar panel. The panel area is one of the indicators that users use when considering purchasing a solar power generation device.

[0080] The weight of the solar panel is stored in the "Panel Weight" field. Panel weight is one of the indicators that users use when considering purchasing a solar power generation system (because it increases the burden on the building).

[0081] The warranty period (the period during which free repairs are possible) of the solar cell device is stored in the warranty period item. The warranty period is one of the indicators that users use when considering purchasing a solar power generation device.

[0082] The expected power generation amount field stores the average amount of power that can be expected from the solar panel. The expected power generation amount is one of the indicators that users use when considering purchasing a solar power generation device.

[0083] The usable temperature range field stores the temperature range within which the solar power generation device can generate a specified amount of power. This is because the amount of power generated and durability of a solar power generation device change depending on, for example, low or high temperatures.

[0084] The usable humidity range field stores the humidity range within which the solar power generation device can generate a specified amount of power. This is because the amount of power generated and durability of the solar power generation device change depending on, for example, low or high humidity.

[0085] The tilt angle field stores the maximum installation angle at which the solar power generation system can generate a specified amount of power. For example, there are restrictions on installation on existing buildings with large roof angles, and there are solar power generation systems with restrictions on tilt angle.

[0086] The items of usable temperature, usable humidity range, and tilt angle are examples of environmental characteristics that indicate the environment in which the solar power generation device is installed.

[0087] The photovoltaic power generation device data may include the type of solar cell, the manufacturer's name, performance, installation location, and the like, in addition to the information shown in the figure.

[0088] <Action or Processing> Next, a flow of determining whether or not a photovoltaic power generation device can be installed in an existing building by the photovoltaic power generation device installation support system 100 will be described with reference to Fig. 8. Fig. 8 is a sequence diagram illustrating a process in which the photovoltaic power generation device installation support system 100 presents photovoltaic power generation devices that can be installed in an existing building based on building data, non-life insurance data, and photovoltaic power generation device data.

[0089] 8, it is assumed that the data shown in FIGS. 5 to 7 are stored in advance in the building data storage device 51, the non-life insurance data storage device 52, and the photovoltaic power generation device data storage device 53.

[0090] S1: The terminal device 30 is connected to the information processing system 10 and displays a solar power generation device search screen generated by the screen generation unit 12 of the information processing system 10. An example of the solar power generation device search screen is shown in FIG. 9. A user who wants to know whether a solar power generation device can be installed in an existing building inputs search criteria for a solar power generation device into the solar power generation device search screen displayed by the terminal device 30. The operation reception unit 33 accepts the input of the search criteria. The user may input search criteria for multiple existing buildings at once.

[0091] The search criteria can be information specifying an existing building (for example, identification information of an existing building in a building data storage device), or, as shown in Figure 9, the user can specify data about the existing building (remaining legal life, remaining physical life, solar cell installation area, and required power generation amount per hour, etc.).

[0092] S2: The communication unit 31 of the terminal device 30 transmits a search request for a photovoltaic power generation device, in which search conditions are specified, to the information processing system 10. The communication unit 11 of the information processing system 10 receives the search request.

[0093] S3: When the communication unit 11 receives a search request specified by the identification information of an existing building, the statutory useful life determination unit 13 acquires building data associated with the identification information from the building data storage device 51 via the communication unit 11. If the search conditions include the data of the existing building shown in Figure 9, the processing of step S3 may be omitted.

[0094] S4: The statutory useful life determination unit 13 determines whether the remaining statutory useful life obtained from the building data or input by the user is equal to or longer than the operating period of the photovoltaic power generation device. The operating period of the photovoltaic power generation device may be predetermined regardless of the photovoltaic power generation device. In this case, the operating period of the photovoltaic power generation device is, for example, about 20 years, but 20 years is just one example. Furthermore, if the operating period of the photovoltaic power generation device varies depending on the photovoltaic power generation device, the determination is made using the operating periods of several representative photovoltaic power generation devices. In this case, it is sufficient that the operating period of at least one photovoltaic power generation device meets the remaining statutory useful life (remaining statutory useful life ≧ operating period of one or more photovoltaic power generation devices).

[0095] S5: If the remaining statutory useful life is equal to or greater than the operation period of the photovoltaic power generation device, the building strength determination unit 16 stores the building strength obtained from the building data or input by the user for later processing.

[0096] S6: If the remaining legal useful life is less than the operation period of the photovoltaic power generation device, the physical useful life determination unit 14 obtains the remaining physical useful life obtained from the building data or input by the user.

[0097] S7: The physical useful life determination unit 14 determines whether the remaining statutory useful life obtained from the building data or input by the user is equal to or longer than the operation period of the solar power generation device. The operation period of the solar power generation device may be the same as in step S4. Based on the determination in step S7, even if the remaining statutory useful life of the existing building is not equal to or longer than the operation period of the solar power generation device, it can be determined based on technical grounds that the solar power generation device can be installed in the existing building if it has a sufficient remaining physical useful life.

[0098] If the remaining statutory useful life is not equal to or greater than the operation period of the solar power generation device and the remaining physical useful life is not equal to or greater than the operation period of the solar power generation device, the information processing system 10 determines that the solar power generation device cannot be installed in the existing building. In this case, the screen generation unit 12 generates a screen indicating that the solar power generation device cannot be installed in the existing building, and the communication unit 11 transmits screen information of this screen to the terminal device 30. The terminal device 30 displays a screen indicating that the solar power generation device cannot be installed in the existing building, so the user can understand that the solar power generation device cannot be installed in the existing building.

[0099] S8: If the remaining legal useful life is equal to or greater than the operation period of the solar power generation device, or if the remaining physical useful life is equal to or greater than the operation period of the solar power generation device, the insurance determination unit 15 acquires non-life insurance data from the non-life insurance data storage device 52. This is so that the insurance determination unit 15 can determine whether or not non-life insurance is available for the solar power generation device installed on the existing building, and decide the non-life insurance to be taken out for the solar power generation device.

[0100] If the remaining statutory useful life is equal to or longer than the operation period of the solar power generation device, the processing of step S8 may be omitted. In other words, since the statutory useful life of the existing building is met, the determination of whether there is a rational basis based on property insurance can be omitted.

[0101] S9: The insurance determination unit 15 searches the non-life insurance data for non-life insurance that satisfies the following conditions (i) and (ii): Based on the conditions (i) and (ii), it is determined whether the insurance company recognizes that there is a rational basis for installing a solar power generation system on an existing building. (i) Property insurance with a remaining physical useful life equal to or greater than the remaining physical useful life obtained from the building data or input by the user (ii) Property insurance with a building strength equal to or greater than the building strength obtained from the building data or entered by the user (i) and (ii) may be AND conditions or OR conditions. The user may be able to set whether to use either or both of (i) and (ii) as conditions. If there is non-life insurance that satisfies conditions (i) and (ii), the insurance decision unit 15 creates a list of such non-life insurance.

[0102] Note that the insurance determination unit 15 may determine that there is non-life insurance that satisfies conditions (i) and (ii) by multiplying the unit area premium of the non-life insurance by a coefficient greater than 1 to estimate a unit area premium that is higher than usual, even if the non-life insurance does not satisfy conditions (i) and (ii). This is because the final choice of non-life insurance is up to the user. Similarly, the insurance determination unit 15 may determine that there is non-life insurance that satisfies conditions (i) and (ii) by multiplying the unit area compensation amount of the non-life insurance by a coefficient less than 1 to estimate a unit area compensation amount that is lower than usual, even if the non-life insurance does not satisfy conditions (i) and (ii).

[0103] The insurance determination unit 15 may also determine whether or not to provide property insurance for the solar power generation device, taking into account the environmental characteristics of the solar power generation device. The environmental characteristics of the solar power generation device are, for example, one or more of the usable temperature, usable humidity, and tilt angle. The usable temperature, usable humidity, and tilt angle are also set in the property insurance data. Using these, the insurance determination unit 15 determines whether or not property insurance is available for the solar power generation device installed in an existing building if there is a solar power generation device whose environmental characteristics match those of the property insurance data, and creates a list of such property insurance. By taking the environmental characteristics of the solar power generation device into consideration when selecting property insurance, it is possible to limit the property insurance available for solar power generation devices installed in harsh environments, for example. Furthermore, determining appropriate property insurance according to environmental characteristics improves the predictability of property insurance.

[0104] Since the photovoltaic power generation device to be installed has not been decided when determining the environmental characteristics, the insurance determination unit 15 may determine that there is property insurance available for the photovoltaic power generation device to be installed in the existing building if there is at least one photovoltaic power generation device whose environmental characteristics match those of the property insurance data. Also, the user may specify in advance (for example, when inputting search conditions) the photovoltaic power generation device and the environment to be installed. The insurance determination unit 15 searches for a photovoltaic power generation device whose environmental characteristics match those of the property insurance data within the range of the photovoltaic power generation device and environment specified by the user.

[0105] Regarding environmental characteristics, even for non-life insurance that does not satisfy the environmental characteristics, the insurance decision unit 15 may estimate the unit area insurance premium higher than usual by multiplying the unit area insurance premium by a coefficient greater than 1. This is because the final choice of non-life insurance is up to the user. Similarly, even for non-life insurance that does not satisfy the environmental characteristics, the insurance decision unit 15 may estimate the unit area insurance premium lower than usual by multiplying the unit area insurance compensation amount by a coefficient less than 1.

[0106] S10: If there is a non-life insurance that satisfies the conditions (i) and (ii), the screen generation unit 12 of the information processing system 10 generates a non-life insurance list screen. The non-life insurance displayed in the non-life insurance list is non-life insurance that meets (i) and (ii), the conditions, and environmental characteristics, or that is deemed to meet the conditions by adjusting the insurance premium or compensation amount even if it does not meet the conditions.

[0107] The communication unit 11 of the information processing system 10 transmits screen information of the non-life insurance list screen to the terminal device 30. The display of the non-life insurance list screen means that the remaining physical useful life is equal to or greater than the operation period of the solar power generation device, and that the insurance company has recognized that there is a reasonable basis for installing the solar power generation device in the existing building.

[0108] The communication unit 31 of the terminal device 30 receives screen information of the non-life insurance list screen. The display control unit 32 of the terminal device 30 displays the non-life insurance list screen based on the screen information. Figure 10 shows an example of the non-life insurance list screen (an example of a first screen).

[0109] S11: The property insurance list screen is displayed, allowing the user to confirm that there is property insurance available for the solar power generation system to be installed on the existing building. The user inputs an operation to continue the process into the terminal device 30. The operation reception unit 33 receives the input.

[0110] If there is no property insurance that satisfies or is deemed to satisfy the conditions (i) and (ii), the screen generation unit 12 of the information processing system 10 generates a screen indicating that there is no property insurance available, and the communication unit 11 transmits the screen information to the terminal device 30. Since the terminal device 30 displays a screen indicating that there is no property insurance available, the user can understand that he or she cannot take out property insurance even if he or she installs a solar power generation system on an existing building.

[0111] S12: In response to the user's operation to continue the process, the communication unit 31 of the terminal device 30 requests the information processing system 10 to continue the process.

[0112] S13: The communication unit 11 of the information processing system 10 receives the processing continuation, and the building strength determination unit 16 determines whether the building strength acquired from the building data or input by the user is equal to or greater than the load of the photovoltaic power generation device. Strictly speaking, the load of a photovoltaic power generation device varies depending on the photovoltaic power generation device, but there are not significant differences. Therefore, the building strength determination unit 16 may use the heaviest panel load among commercially available panel loads. Alternatively, the building strength determination unit 16 may use the heaviest panel load, the lightest panel load, or the average panel load among the panel loads stored in the photovoltaic power generation device data as the load of the photovoltaic power generation device.

[0113] S14: If the building strength is equal to or greater than the load of the photovoltaic power generation device, the photovoltaic power generation device determination unit 17 acquires photovoltaic power generation device data from the photovoltaic power generation device data storage device 53.

[0114] S15: The photovoltaic power generation device determination unit 17 searches the photovoltaic power generation device data for a photovoltaic power generation device with a warranty period equal to or longer than the remaining physical useful life. This makes it possible to prevent the installation of a photovoltaic power generation device whose remaining physical useful life of an existing building does not meet the warranty period. Note that a photovoltaic power generation device with a warranty period longer than the remaining physical useful life may be determined. However, in this case, there is a risk that the photovoltaic power generation device will be damaged before the warranty period expires. Therefore, the photovoltaic power generation device determination unit 17 may multiply the panel unit price by a coefficient of 1 or more to estimate the panel unit price higher than usual. This is because the final selection of a photovoltaic power generation device is at the discretion of the user.

[0115] Alternatively, the photovoltaic power generator determination unit 17 may change the warranty period of the photovoltaic power generator data to a value equal to the remaining physical useful life, and determine that the photovoltaic power generator matches the search.

[0116] S16: The screen generation unit 12 of the information processing system 10 generates a solar power generation unit list screen including a list of the solar power generation units determined by the solar power generation unit determination unit 17. The communication unit 11 of the information processing system 10 transmits screen information of the solar power generation unit list screen to the terminal device 30.

[0117] The communication unit 31 of the terminal device 30 receives screen information of the solar power generation unit list screen. The display control unit 32 of the terminal device 30 displays the solar power generation unit list screen based on the screen information. Fig. 11 shows an example of the solar power generation unit list screen (an example of a second screen).

[0118] S17: The user can select a solar power generation device to contract with from the solar power generation devices displayed on the solar power generation device list screen and enter into a contract.

[0119] S18: Once the user has signed a contract for the solar power generation system, they can consider purchasing property insurance again. Since there is already a rational basis for the user to be able to take out property insurance, it is up to the user whether or not to take out property insurance. Since it is known that there is property insurance available for the solar power generation system, the user can search for property insurance and take out the desired property insurance. Figure 12 shows an example of the property insurance search screen.

[0120] S19: If the building strength is not greater than the load of the solar power generation device, the screen generation unit 12 of the information processing system 10 generates a screen indicating that there is no solar power generation device that can be installed in the existing building, and the communication unit 11 transmits the screen information to the terminal device 30. The terminal device 30 displays a screen indicating that a solar power generation device cannot be installed in the existing building, so the user can understand that a solar power generation device cannot be installed in the existing building.

[0121] In FIG. 8, the information processing system 10 determines whether there is technical basis and rational basis, but a web application or native application running on the terminal device 30 can also determine whether there is technical basis and rational basis.

[0122] A console may also be connected to the information processing system 10. The console collectively refers to a display device such as a display and an input device such as a keyboard used by a user. In other words, a user may operate the information processing system 10 directly from the console. In the console, information processing is performed on the information processing system 10 side, and information is input and output by the console.

[0123] <Screen example> The screens will be described with reference to FIGS.

[0124] <<Solar power generation equipment search screen>> FIG. 9 is a photovoltaic power generation device search screen 210 displayed by the terminal device 30. The photovoltaic power generation device search screen 210 is a screen for the user to search for a photovoltaic power generation device that can be installed in an existing building. As described above, the user can omit inputting data into the input fields in FIG. 9 by specifying an existing building. FIG. 9 is a screen for the user to input data (search conditions) related to an existing building, etc., in order to search for a photovoltaic power generation device.

[0125] In the remaining legal useful life field, the user inputs the remaining legal useful life of the existing building. The remaining legal useful life may be obtained by the user from a building database or may be input based on the structure.

[0126] In the remaining physical life field, the user inputs the remaining physical life of the existing building. The remaining physical life may be obtained by the user from a building database or calculated from design drawings.

[0127] The user inputs the building strength of the existing building in the building strength field. The building strength may be obtained by the user from a building database or calculated from design drawings.

[0128] In the solar cell installation area field, the user inputs the area of ​​the existing building where solar power generation equipment can be installed. The solar cell installation area can be obtained by the user from the building database (roof area field) or calculated from the design drawings.

[0129] In the field for the amount of power generation required per hour, the user enters the amount of power they plan to generate from the solar power generation system they plan to install. This field is used to search for property insurance or calculate insurance premiums and compensation amounts. This is because some property insurance policies may determine whether they cover solar power generation systems and may also have different premiums and compensation amounts depending on the amount of power generation.

[0130] <<Property Insurance List Screen>> 10 is a property insurance list screen 220 displayed by the terminal device 30. The property insurance list screen 220 displays a list of property insurance policies that can be taken out on a photovoltaic power generation system, determined based on data related to the existing building. As described above, the data related to the existing building is at least one of the remaining physical useful life and the building strength.

[0131] The property insurance item displays the brand name of the property insurance, the name of the insurance company, etc.

[0132] The unit area premium item is the unit area (e.g. 1m 2 The insurance premium per unit area is displayed. The unit area insurance premium may be the value included in the insurance data, or may be a value multiplied by a coefficient greater than 1 if it does not meet the conditions (i) and (ii) above or does not match the environmental characteristics.

[0133] The unit area compensation amount item is the amount of compensation per unit area (e.g. 1m) in the event of damage to a solar power generation device. 2 The compensation amount per unit area is displayed. The compensation amount per unit area may be the value included in the property insurance data, or may be a value multiplied by a coefficient less than 1 if it does not meet the conditions (i) and (ii) above or does not match the environmental characteristics.

[0134] The remaining physical useful life item displays the remaining physical useful life of the existing building used to search for the solar power generation equipment.

[0135] The building strength item displays the building strength of the existing building used in the search for the solar power generation device.

[0136] The user can check the property insurance list screen 220 as shown in Figure 10 to confirm that there is a rational basis from the perspective of the property insurance company for installing a solar power generation system on an existing building. In addition, the insurance premium per unit area and the compensation amount per unit area are displayed, so the user can also confirm whether there is a rational basis by checking whether the insurance premium per unit area is extremely high or the compensation amount per unit area is extremely low.

[0137] Although Figure 10 only displays the remaining physical useful life and building strength, other factors such as the usable temperature range, usable humidity range, and tilt angle used in determining the property insurance may also be displayed. Furthermore, if a coefficient is multiplied by the unit area insurance premium or unit area compensation amount, this coefficient should also be displayed. This allows the user to understand how much the unit area insurance premium or unit area compensation amount has changed.

[0138] <<Photovoltaic power generation equipment list screen>> 11 is a photovoltaic power generation unit list screen 230 displayed by the terminal device 30. The photovoltaic power generation unit list screen 230 displays a list of photovoltaic power generation units of existing buildings whose remaining physical useful life is equal to or exceeds the warranty period.

[0139] In the panel name field, at least one of the brand name, manufacturer, and distributor of the solar power generation device is displayed.

[0140] The panel unit price section displays the panel unit price of the solar power generation equipment data. Users can compare solar power generation equipment using the panel unit price as a reference.

[0141] The panel area field displays the panel area of ​​the solar power generation system data. Users can calculate how many panels can be installed on the roof based on the panel area and the roof area of ​​the existing building.

[0142] The panel weight section displays the panel weight of the solar power generation system data, allowing users to compare solar power generation systems based on panel weight and the building strength of existing buildings.

[0143] The warranty period field displays the warranty period for the solar power generation equipment data, allowing users to compare solar power generation equipment based on the warranty period.

[0144] The remaining physical useful life item displays the remaining physical useful life of the existing building used to search for the solar power generation equipment.

[0145] The building strength item displays the building strength of the existing building used in the search for the solar power generation device.

[0146] The user can determine which photovoltaic power generation device to install in an existing building by viewing the photovoltaic power generation device list screen 230 in FIG. 11. The display of the photovoltaic power generation device list screen 230 indicates that there is a technical basis (greater than the remaining physical useful life or the operating period of the photovoltaic power generation device) and a rational basis (based on data about the existing building, it has been confirmed that there is property insurance available for the photovoltaic power generation device). Therefore, the user can install a photovoltaic power generation device with a justification. Furthermore, since the remaining physical useful life of the existing building is greater than the warranty period, the user can select a photovoltaic power generation device that is guaranteed for at least the warranty period.

[0147] <<Property Insurance Search Screen>> 12 shows a property insurance search screen 240 displayed by the terminal device 30. The property insurance search screen 240 is a screen for the user to search for property insurance to take out on a solar power generation system installed on an existing building. As described above, it is up to the user whether or not to take out property insurance on the solar power generation system.

[0148] In the remaining legal useful life field, the user inputs the remaining legal useful life of the existing building. The remaining legal useful life may be obtained by the user from a building database or may be input based on the structure.

[0149] In the remaining physical life field, the user inputs the remaining physical life of the existing building. The remaining physical life may be obtained by the user from a building database or calculated from design drawings.

[0150] The user inputs the building strength of the existing building in the building strength field. The building strength may be obtained by the user from a building database or calculated from design drawings.

[0151] In the solar cell installation area field, the user inputs the area of ​​the existing building where solar power generation equipment can be installed. The solar cell installation area can be obtained by the user from the building database (roof area field) or calculated from the design drawings.

[0152] The insurance determination unit 15 searches for property insurance that satisfies the remaining statutory useful life, remaining physical useful life, and building strength, and displays the search results on the terminal device 30. The search results may be similar to those shown in FIG. 10. In this way, the user can search again for property insurance that can be taken out for a solar power generation system to be installed on an existing building.

[0153] <Cost reduction effect 1> Specific effects of determining whether or not to install a photovoltaic power generation system according to this embodiment will be described.

[0154] The legal useful life of a newly constructed steel-framed logistics warehouse built in 1988 is 34 years, and the remaining legal useful life as of 2022 is 0 years. When a user performs an evaluation using this embodiment, the physical useful life of the warehouse is 87 years, and the remaining physical useful life as of 2022 is 53 years. Based on the predictability of property insurance and a building strength evaluation, a PPA operator (a business that sells electricity through a power purchase agreement) decides to enter into a 20-year contract for a solar power generation system. By replacing the high electricity bill of 32.5 yen / kWh (excluding tax) with a cheaper PPA price of 12.5 yen / kWh (excluding tax) for 300,000 kWh / year of electricity supplied by a solar power generation system, the owner of the logistics warehouse can reduce expenses by approximately 6 million yen per year and contribute to the environment by reducing CO2 emissions by 129 tons per year.

[0155] Comparing with comparative technologies. The legal useful life of a steel-framed logistics warehouse built in 1988 is 34 years, and as of 2022, there will be 0 years left of the legal useful life. For this reason, it is impossible for a PPA operator to install solar power generation equipment and conclude a 20-year PPA contract, meaning the owner of the logistics warehouse will have to continue paying high electricity bills and will not be able to contribute to the environment by reducing CO2 emissions.

[0156] The differences between this embodiment and the comparative technology are as follows: Satisfying the cost reduction needs of logistics warehouse owners (-6 million yen / year) and decarbonization needs (-129 t CO2 / year), and expanding business opportunities for PPA operators.

[0157] <Cost reduction effect 2> The statutory useful life of a steel-framed factory built in 1988 is 34 years, and the remaining years of the statutory useful life as of 2022 are 0 years. When the user performed an evaluation according to this embodiment, the physical useful life of a logistics warehouse was 39 years, and the remaining years of the physical useful life as of 2022 were 5 years. The owner of the factory determined that the possibility of continuing to use the factory building was low, and gave up on installing a solar power generation system.

[0158] Compare with comparative technologies. The statutory useful life of a steel-framed factory built in 1988 was 34 years, and as of 2022, there were 0 years left of the statutory useful life, so the owner of the factory decided to install a solar power generation system. The solar power generation system installation company installed solar power generation systems for a total of 50 million yen under a 20-year usage plan, and the factory owner was able to reduce his electricity bill by approximately 4 million yen per year. However, five years later, in 2027, the deterioration of the building made it difficult for the factory to continue operating, and he ended up not being able to recover the 30 million yen investment in the additional solar power generation system.

[0159] The differences between this embodiment and the comparative technology are as follows: Improvement in predictability of investment recovery decisions for factory owners when introducing solar power generation equipment.

[0160] <Major Effects> The photovoltaic power generation device installation support system 100 of this embodiment technically evaluates the physical useful life of an existing building and supports a decision on whether or not to install a photovoltaic power generation device. That is, when installing a photovoltaic power generation device on the roof or the like of an old building, the photovoltaic power generation device installation support system 100 can make a decision on installation based on the technical grounds that the remaining physical useful life is equal to or longer than the operation period.

[0161] Furthermore, in this embodiment, based on data on the existing building, it can be confirmed that there is a low probability that the installed solar power generation system will become unusable due to the remaining legal useful life of the existing building if there is property insurance available for the solar power generation system. Therefore, by determining whether or not there is property insurance available, the solar power generation system installation support system 100 can determine whether or not it is acceptable to install the solar power generation system based on rational grounds.

[0162] For existing buildings with a short remaining legal useful life, if the remaining physical useful life is equal to or exceeds the operating period of the solar power generation equipment and applicable property insurance can be determined, the possibility of reducing electricity bills and CO2 emissions will increase. The possibility of installing solar power generation equipment on the roof of existing buildings, where installation was previously abandoned due to the short remaining legal useful life, will increase.

[0163] <Other application examples> The best mode for carrying out the present invention has been described above using examples, but the present invention is not limited to these examples in any way, and various modifications and substitutions can be made within the scope that does not deviate from the gist of the present invention.

[0164] For example, the terminal device 30 may have the functions of the information processing system 10 shown in Fig. 4. In this case, the terminal device 30 communicates with the building data storage device 51, the non-life insurance data storage device 52, and the solar power generation device data storage device 53 in response to user operations, and determines whether there are technical and rational grounds for installing a solar power generation device in an existing building.

[0165] Although the present embodiment describes the installation of a solar power generation system in an existing building, the technical and rational grounds may be determined for devices other than a solar power generation system, as long as the device is installed in the existing building for the long term. For example, a natural refrigerant heat pump water heater, an air conditioner, a heater, a hydrogen generator, or the like may be installed in the existing building.

[0166] Furthermore, the configuration examples in Figure 4 and the like are divided according to main functions to make it easier to understand the processing by the terminal device 30 and the information processing system 10. The method of dividing the processing units or the names thereof does not limit the present invention. The processing by the terminal device 30 and the information processing system 10 can also be divided into more processing units depending on the processing content. Furthermore, the processing can also be divided so that one processing unit includes more processes.
