[Diagram 2]FIG. 2 is a block diagram of a system including a management device according to the embodiment. [Diagram 3] FIG. 3 is a schematic diagram showing an example of a list displayed on the output device according to the embodiment. [Figure 4] FIG. 4 is a flowchart showing an example of the operation of the system according to the embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] <Embodiment> Hereinafter, the management system for the photovoltaic sheet 4 according to this embodiment will be described in detail with reference to the accompanying drawings.

[0023] The management system for a photovoltaic sheet 4 according to this embodiment (hereinafter sometimes simply referred to as the "management system") is a system that manages multiple photovoltaic sheets 4 before shipping. For example, as shown in FIG. 1, multiple photovoltaic sheets 4 are stored in multiple storage compartments 13. Each storage compartment 13 is assigned unique identification information (hereinafter referred to as storage compartment identification information). Each photovoltaic sheet 4 is also assigned unique identification information (hereinafter referred to as sheet identification information).

[0024] 2, the management system includes a reception unit 211 that receives input of sheet identification information, and a registration unit 212. The registration unit 212 associates the storage section identification information with the sheet identification information of the photovoltaic sheet 4 accommodated in the storage section 13 to which the storage section identification information is assigned.

[0025] According to the management system of this embodiment, the storage compartments 13 and the photovoltaic sheets 4 can be registered in association with each other, so the management system can manage the individual information of the photovoltaic sheets 4 stored in each of the multiple storage compartments 13. This makes it easy to find, for example, the photovoltaic sheets 4 that need to be prepared for shipment.

[0026] In the following embodiment, a management device 2 in which most of the functions of the management system are integrated in one housing will be described as an example. However, it is not essential for a management system to have multiple functions integrated in one housing, and for example, the components of the management system may be distributed across multiple housings. Also, some of the functions of the management system may be realized by the cloud (cloud computing) or the like.

[0027] As shown in Fig. 2, the entire system including the management device 2 comprises a storage facility 1 having a plurality of storage compartments 13, the management device 2, and an output device 3. The storage facility 1 comprises a plurality of sensors 12 that acquire information relating to the environment of the storage compartments 13 (hereinafter referred to as environmental information), and a reader 11 for reading IC tags, which will be described later. The sensors 12, the reader 11, the management device 2, and the output device 3 are connected to each other so as to be able to communicate with each other via wires or wirelessly. Each element constituting the system will be described in more detail below.

[0028] (Photovoltaic power generation sheet 4) The photovoltaic sheet 4 is a managed object in the management system. The photovoltaic sheet 4 is flexible. As shown in FIG. 1, the photovoltaic sheet 4 can be stored in the storage section 13 in a state where it is wound in a reel shape. The photovoltaic sheet 4 has a power generation unit that receives sunlight and generates electricity. The power generation unit is disposed between a flexible back sheet and a flexible protective sheet that is overlaid on the back sheet. A transparent sealant is filled between the back sheet and the protective sheet. The back sheet and the protective sheet are made of, for example, a soft synthetic resin. The photovoltaic sheet 4 wound in a reel shape may be wound around a reel or may be wound without a reel. When stored in a reeled state, it is possible to suppress the power generation unit from receiving light, and at the same time, it is possible to easily carry the sheet by hand, thereby improving the workability during transportation.

[0029] The photovoltaic sheet 4 may be stored in the storage compartment 13 in a stacked sheet form without being rolled up. In this case, the area required to store the photovoltaic sheet 4 increases compared to when the photovoltaic sheet 4 is rolled up in a reel and stored, but the stress applied to the photovoltaic sheet 4 decreases.

[0030] The power generation section generates electricity from sunlight by utilizing the photovoltaic effect. The power generation section is flexible. Only one power generation section may be provided for one solar power generation sheet 4, or the power generation section may be divided into multiple locations. The power generation section is an assembly of multiple power generation cells. The power generation section preferably has a monolithic structure. In a power generation section having a monolithic structure, multiple power generation cells are mechanically joined and electrically connected to each other.

[0031] A power generating cell is a photoelectric conversion element that utilizes the photovoltaic effect and is the smallest unit of an element capable of generating electricity. A power generating cell uses, for example, amorphous silicon, perovskite, non-silicon material (semiconductor material CIGS) or the like for the photoelectric conversion layer.

[0032] Each photovoltaic sheet 4 is assigned sheet identification information, which is unique identification information. The sheet identification information is for identifying each photovoltaic sheet 4, and may be, for example, a manufacturing number. The sheet identification information is not limited to the manufacturing number, and may be, for example, a suitable combination of numbers, symbols, alphabets, hiragana, katakana, kanji, figures, etc., as long as they are not duplicated. The sheet identification information may be provided to the photovoltaic sheet 4 by printing, engraving, drawing, attaching a printed matter, barcode, QR code (registered trademark), etc. In this case, the sheet identification information is preferably provided on the back side (non-power-generating surface) of the power-generating surface of the photovoltaic sheet 4. When the photovoltaic sheet 4 is stored in a rolled state, it is preferable to roll the photovoltaic sheet 4 so that the non-power-generating surface is on the outside of the power-generating surface in each layer, and to provide the sheet identification information on the outermost peripheral surface of the photovoltaic sheet 4. In this embodiment, an IC tag on which the sheet identification information is recorded is attached to the photovoltaic sheet 4.

[0033] An active tag is preferably used as the IC tag used in the photovoltaic sheet 4. In this case, it is preferable that the power supply to the IC tag is not from a built-in battery, but is supplied from the power generation section of the photovoltaic sheet 4. However, the IC tag is not limited to an active tag, and may be a passive tag or a semi-passive tag.

[0034] As described above, the photovoltaic sheet 4 according to this embodiment has a power generation section disposed between a flexible back sheet and a flexible protective sheet overlaid on the back sheet. Because the back sheet and protective sheet contain a large amount of resin material, the photovoltaic sheet 4 according to this embodiment is relatively susceptible to deterioration. For this reason, the photovoltaic sheet 4 has the property of being easily deteriorated when stored at high temperatures and high humidity in the summer or when exposed to sunlight.

[0035] (Storage 1) As shown in FIG. 1, the storage cabinet 1 is divided into a plurality of storage compartments 13. The plurality of storage compartments 13 are preferably divided by shelves 131 and partitions 132. However, the storage compartments 13 do not necessarily have to be physically divided, as long as the storage space is divided without the partitions 132. Also, a physically divided compartment may be further divided virtually, and each compartment may be defined as one storage compartment. For example, the divided space may be divided into a front side and a back side, and one partitioned compartment may be divided into two storage compartments.

[0036] One storage compartment 13 stores one photovoltaic sheet 4. As described above, the photovoltaic sheet 4 stored in the storage compartment 13 is preferably rolled up. This makes it possible to reduce the space required for the storage compartment 13. However, the photovoltaic sheet 4 stored in the storage compartment 13 does not have to be rolled up. For example, a flat photovoltaic sheet 4 may be stored in a flat, drawer-shaped storage compartment 13.

[0037] Each storage compartment 13 is assigned storage compartment identification information, which is unique identification information. The storage compartment identification information is for identifying each storage compartment 13, and is assigned, for example, A1, B1, C1, ... from the top row on one side in the left-right direction, and A2, B2, C2, ... from the second row on one side in the right-left direction. The storage compartment identification information may be an appropriate combination of numbers, symbols, alphabets, hiragana, katakana, kanji, figures, etc., as long as they do not overlap with each other.

[0038] It is preferable that each storage compartment 13 is provided with an IC tag on which the assigned storage compartment identification information is recorded. This allows both the storage compartment identification information and the sheet identification information to be read simultaneously when read by the reader 11, and also allows the correspondence between the photovoltaic sheets 4 stored in the storage compartments 13 to be sent to the management device 2.

[0039] It is preferable to use a passive tag as the IC tag used in the storage compartment 13. However, the IC tag used in the storage compartment 13 is not limited to a passive tag, and may be an active tag or a semi-passive tag.

[0040] The reader 11 can read the sheet identification information of the photovoltaic sheet 4 stored in the storage 1, and output the sheet identification information to the management device 2. The reader 11 can also read the storage section identification information of the storage section 13 in which the photovoltaic sheet 4 having the sheet identification information is stored, and output the storage section identification information to the management device 2. The reader 11 is preferably disposed in the vicinity of the storage 1.

[0041] The storage facility 1 preferably has a sensor 12. The sensor 12 can acquire environmental information of the storage area 13 and output the detection result to the management device 2. The environmental information includes at least one of the temperature, humidity, and illuminance of the storage area 13, but preferably includes all of the temperature, humidity, and illuminance of the storage area 13. The sensor 12 preferably has multiple types of sensor elements depending on the information to be acquired as the environmental information. Examples of the sensor elements include a temperature detection element, a humidity detection element, and an illuminance detection element. By acquiring the environmental information of the storage area 13, as described below, the management device 2 can predict the degree of deterioration of the photovoltaic sheet 4 stored in the storage area 13, and therefore can determine the priority of shipping the photovoltaic sheet 4.

[0042] Instead of providing a sensor 12 in each storage compartment 13, a thermosensor (such as an infrared camera) that detects the temperatures of multiple storage compartments 13 at once may be provided.

[0043] (Management device 2) The management device 2 includes, for example, a personal computer or a server computer. That is, the management device 2 includes a computer system having one or more processors and a memory. At least a part of the functions of the management device 2 is realized by the processor of the computer system executing a program recorded in the memory of the computer system. The program may be recorded in the memory, or may be provided through a telecommunication line such as the Internet, or may be recorded on a non-transitory recording medium such as a memory card and provided.

[0044] 2, the management device 2 includes a processing unit 21 that executes processing of the management device 2, and a storage unit 22. The processing unit 21 is realized by a processor that executes various processes according to programs stored in the storage. Examples of the processor include a CPU (Central Processing Unit), an MPU (Micro Processing Unit), a GPU (Graphics Processing Unit), and a microprocessor.

[0045] The storage unit 22 stores information handled by the management device 2. The storage unit 22 is realized by, for example, a Read Only Memory (ROM), a Random Access Memory (RAM), an Electrically Erasable Programmable Read Only Memory (EEPROM), or the like.

[0046] (Processing section 21) The processing unit 21 includes a reception unit 211, a registration unit 212, an environmental information acquisition unit 213, a delivery priority determination unit 214, and an output unit 215. The reception unit 211, the registration unit 212, the environmental information acquisition unit 213, the delivery priority determination unit 214, and the output unit 215 merely indicate functions realized by the processing unit 21, and do not necessarily indicate actual configurations. For example, the functions may be realized by a cloud server or the like.

[0047] (Reception Department 211) The receiving unit 211 receives input of sheet identification information. The receiving unit 211 can also receive input of storage section identification information. However, the storage section identification information does not have to be input into the system via the receiving unit 211, and may be stored in the storage unit 22 in advance.

[0048] When the receiving unit 211 receives the input of the sheet identification information and the storage section identification information transmitted from the reader 11, it can output the sheet identification information and the storage section identification information to the registration unit 212. The receiving unit 211 may receive not only the information transmitted from the reader 11, but also the sheet identification information and / or the storage section identification information input from another input device (e.g., a keyboard, a mouse, a microphone, etc.).

[0049] (Registration unit 212) The registration unit 212 registers the storage section identification information in association with the sheet identification information of the photovoltaic sheet 4 stored in the corresponding storage section 13. The registered information is recorded in the memory unit 22 and is also output to the delivery priority determination unit 214.

[0050] The registration unit 212 refers to the input storage section identification information and searches whether the same storage section identification information is registered in the storage unit 22. If sheet identification information has already been registered for the input storage section identification information, the registration unit 212 can overwrite the already registered sheet identification information with the sheet identification information received by the reception unit 211 to update it and register it in association with the storage section identification information. If the input storage section identification information is new, the registration unit 212 can newly associate the sheet identification information and storage section identification information received by the reception unit 211 with each other and register them in the storage unit 22.

[0051] The registration unit 212 preferably registers date information indicating the date when the solar power generation sheet 4 started to be stored in the storage section 13 (hereinafter, storage start date) in association with the sheet identification information and the storage section identification information. The date information is preferably information of year, month, and date, but may be only year and month, or may include not only year, month, and date but also hour and minute. This allows the management device 2 to manage the storage period for each of the multiple solar power generation sheets 4 stored in the storage section 13.

[0052] (Environmental Information Acquisition Department 213) The environmental information acquisition unit 213 acquires environmental information corresponding to the storage section 13, and registers the environmental information in association with the storage section identification information of the storage section 13. The information registered by the environmental information acquisition unit 213 is recorded in the storage unit 22 and is also output to the delivery priority determination unit 214.

[0053] The environmental information acquisition unit 213 preferably acquires, as environmental information, a detection result by the sensor 12 provided in the storage facility 1. The environmental information acquisition unit 213 may acquire, as environmental information, a detection result in real time, every few days, or every season (for example, every three months).

[0054] The environmental information input by the environmental information acquisition unit 213 is not limited to being input from the sensor 12, but may be input from other input devices (for example, a keyboard, a mouse, a microphone, etc.).

[0055] (Shipping priority determination unit 214) The dispatch priority determination unit 214 determines dispatch priorities for the multiple photovoltaic sheets 4 housed in the multiple storage compartments 13 using environmental information. For example, during the daytime, the degree of deterioration differs between the photovoltaic sheets 4 housed in the storage compartment 13 where the sun shines continuously and the photovoltaic sheets 4 housed in the storage compartment 13 where the sun is always shining. In particular, the photovoltaic sheets 4 containing organic components such as perovskite in the power generation cells have a problem that the performance of the power generation unit is significantly reduced if the electricity generated by the power generation unit is not consumed. In addition, there is also a problem that when the power generation unit is partially shaded and the other parts are exposed to sunlight, a reverse voltage is generated, which accelerates deterioration. For this reason, when the photovoltaic sheets 4 housed in the storage compartment 13 are partially exposed to sunlight, it is preferable to determine the dispatch priority, etc., taking this into consideration.

[0056] The dispatch priority determination unit 214 preferably calculates a deterioration index from the environmental information. By accumulating the deterioration index, it is possible to calculate the degree of deterioration during the period from the start of storage in the storage area 13 to the present. The dispatch priority determination unit 214 preferably creates a list, for example, as shown in FIG. 3, using the calculated deterioration degree. In the list, for example, the deterioration degree can be sorted in descending order. By sorting the multiple photovoltaic power generation sheets 4 in the list in order of deterioration degree, the dispatch priority can be grasped at a glance.

[0057] The deterioration index is an index that quantifies the ease of deterioration or the current deterioration degree. It is preferable to use an index that quantifies the deterioration degree per unit time from environmental information as the deterioration index. For example, the deterioration index may be obtained by weighting factors that are likely to affect deterioration, such as temperature, humidity, illuminance, and the deformation degree of the photovoltaic sheet 4, and multiplying each value by a coefficient according to the weighting, and adding up the values ​​to obtain the deterioration index. For example, the deformation degree may be 0 when the photovoltaic sheet 4 is not rolled up, and may be a value inversely proportional to the maximum radius of curvature when the photovoltaic sheet 4 is rolled up. The weighting order of the temperature, humidity, illuminance, and deformation degree may be, for example, temperature, humidity, deformation degree, and illuminance in decreasing order. In addition, the deterioration index may use a value determined from an empirical measurement.

[0058] Furthermore, the delivery priority determination unit 214 may read a preset deterioration index from the storage unit 22 and calculate the deterioration level for each photovoltaic sheet 4 from the time elapsed since the storage start unit, rather than using a deterioration index calculated from environmental information acquired in real time. In this case, it is preferable to set a deterioration index per unit time that takes into account daytime and nighttime hours. Alternatively, the deterioration level may be calculated for each predetermined period (e.g., each day, each week) during the storage period of the photovoltaic sheet 4, and the sum of these deterioration levels may be used as the deterioration index.

[0059] (Output unit 215) The output unit 215 outputs the result of the processing by the processing unit 21 to the output device 3, and displays it on the output device 3. Here, FIG. 3 shows an example of a list displayed by the output device 3. As shown in FIG. 3, the output unit 215 preferably displays the sheet identification information (written as "photovoltaic power generation sheet" in the table) registered by the registration unit 212 in association with the storage section identification information (written as "storage section" in the table). In addition, the output unit 215 preferably displays the information on the priority of dispatch ("degree of deterioration" and "priority order") determined by the dispatch priority determination unit 214. As the priority information, the degree of deterioration may be displayed, or the priority order may be displayed based on the priority. This makes it easy for the user to grasp the priority of dispatch of the photovoltaic power generation sheet 4. Moreover, since the storage section 13 in which the photovoltaic power generation sheet 4 to be dispatched is clearly identified, the workability can be improved.

[0060] It is preferable that the list can be sorted in descending order of deterioration level or in order of priority by pressing a sort button. Also, for example, when the deterioration level exceeds a certain value, the high priority of shipping may be notified by highlighting, changing the text color, blinking, attaching a mark such as a star, or displaying a list of photovoltaic sheets that should be shipped with priority separately from the list.

[0061] (Output device 3) The display screen of the output device 3 is controlled by the output unit 215 of the management device 2. That is, the display screen of the output device 3 is displayed based on the information output from the output unit 215. The output device 3 may be a display installed in a department that arranges for the solar power generation sheets 4. Examples of the output device 3 include a monitor, a display, a touch display, a projector, a smartphone, a tablet terminal, a notebook PC, VR goggles, a head-mounted display, a printer, and a speaker. The output device 3 may be a stationary terminal or a communication terminal owned by each worker.

[0062] (flowchart) Next, an example of the operation of the management system according to this embodiment will be described with reference to a flowchart. As shown in Fig. 4, the management method of the photovoltaic sheet 4 according to this embodiment sequentially executes a reception step (ST1-3), a registration step (ST4), and a priority determination step (ST5, 6).

[0063] The reception step begins with placing the solar power generation sheet 4 in the storage compartment 13 (ST1). The worker uses the reader 11 to read the IC tag to read the storage compartment identification information of the storage compartment 13 that stores the solar power generation sheet 4 and the sheet identification information of the solar power generation sheet 4 (ST2). The reader 11 then transmits the storage compartment identification information and the sheet identification information to the management device 2. The reception unit 211 of the management device 2 receives the storage compartment identification information and the sheet identification information, as well as information indicating the reception date (ST3).

[0064] Next, the registration unit 212 associates and registers the storage section identification information and the sheet identification information (ST4). Subsequently, the delivery priority determination unit 214 acquires environmental information, calculates the deterioration level of the solar power generation sheet 4 and associates it with the sheet identification information associated with the storage section identification information. As a result, the management device 2 determines the delivery priority of the solar power generation sheet 4 (ST5).

[0065] When the priority of the delivery of the photovoltaic sheets 4 is determined, the management device 2 can create a list in order of priority (ST6) and display it on the output device 3.

[0066] <Modification> The above embodiment is merely one of various embodiments of the present invention. The embodiment can be modified in various ways depending on the design, etc., as long as the object of the present invention can be achieved. Modifications of the embodiment are listed below. The modifications described below can be applied in appropriate combination.

[0067] In the above embodiment, when the storage section identification information and the sheet identification information are read by the reader 11, the worker holds the reader 11 over the object to read them. However, for example, the reading operation by the reader 11 may be performed automatically by a robot, or the reading operation may be performed simultaneously with the transportation when the object is transported from the transport vehicle to the storage section 13.

[0068] In addition, the sheet identification information may be received by the reception unit 211, for example, by displaying the storage section identification information on a display and having an operator input the sheet identification information of the stored solar power generation sheet 4 into an input box corresponding to the storage section identification information using a keyboard or the like.

[0069] In the above embodiment, the photovoltaic sheet 4 stored in the storage compartment 13 is wound up in a reel shape, but in the present invention, the photovoltaic sheet does not need to be wound up in a reel shape and may be laid flat, or the photovoltaic sheets 4 laid flat or wound up in a reel shape may be stacked and stored in the storage compartment. When stacking the photovoltaic sheets 4, it is preferable to assign different storage compartment identification information from the bottom up. For example, in one partitioned compartment (e.g., A1), the storage compartment 13 storing the bottommost photovoltaic sheet 4 may be assigned "A1-01", the storage compartment 13 of the photovoltaic sheet 4 above that may be assigned "A1-02", and the storage compartment 13 above that may be assigned "A1-03", etc., with the storage compartment identification information being assigned to include a branch number, or without using a branch number.

[0070] In the above embodiment, the management system outputs information on the priority of shipping the photovoltaic sheets 4, but for example, the priority information may be transmitted to a robot, and the robot may automatically prepare for shipping the corresponding photovoltaic sheet 4. Alternatively, the robot may read the storage section identification information and sheet identification information, determine the priority of shipping, and prepare for shipping the corresponding photovoltaic sheet 4.

[0071] Furthermore, light-emitting elements may be attached to each storage compartment 13, and storage compartments 13 housing photovoltaic sheets 4 with high priority may be notified by the light-emitting elements flashing or lighting up. Furthermore, a display showing a layout diagram of the storage compartments 13 may be used to highlight storage compartments 13 housing photovoltaic sheets 4 with high priority on the display. By installing the display on a transport machine (e.g., a forklift), loading work can be carried out efficiently.

[0072] Also, the sheet identification information can be recorded in association with customer information of the shipping destination. In this case, the individual photovoltaic sheets 4 and the installation date of the photovoltaic sheets 4 can be recorded, and the rate of deterioration after installation can be predicted. Also, based on the number of days of storage, the deterioration index, etc., and the degree of deterioration before shipping, the deterioration after installation can be predicted.

[0073] Since the occupancy rate of the photovoltaic sheets 4 in the multiple storage compartments 13 can be grasped, inventory management of the photovoltaic sheets 4 is easy. In other words, when the number of storage compartments 13 not housing the photovoltaic sheets 4 reaches a certain amount, a notification of additional production may be sent to the production management system. This makes it possible to realize a stable supply of the photovoltaic sheets 4 to general consumers without running out of stock.

[0074] In the above embodiment, the sheet identification information is listed in the list, but correspondingly, for example, information specific to the photovoltaic sheet 4, such as length and width, maximum output during power generation, etc. may be associated and displayed. Also, for example, in the case where a desired size is cut from a reel-shaped photovoltaic sheet 4 for use, the remaining amount of the photovoltaic sheet 4 may be displayed.

[0075] <Summary> As described above, the management system for the solar power generation sheet 4 in this embodiment includes a reception unit 211 that receives input of sheet identification information, which is unique identification information for the solar power generation sheet 4, and a registration unit 212 that associates the sheet identification information of the solar power generation sheet 4 contained in each storage compartment 13 with storage compartment identification information, which is identification information assigned to each of the multiple storage compartments 13.

[0076] Because of this configuration, it is possible to manage the photovoltaic sheets 4 in association with the storage compartments 13 in which the photovoltaic sheets 4 are stored. Therefore, it is possible to manage multiple photovoltaic sheets 4 individually.

[0077] Furthermore, in the management system for the photovoltaic sheet 4, the registration unit 212 registers date information indicating the date on which the photovoltaic sheet 4 started to be accommodated in the accommodation section 13, in association with the corresponding sheet identification information.

[0078] Because of this configuration, the management system can manage the storage period for each of the multiple photovoltaic sheets 4 that is stored in the storage compartment 13.

[0079] The management system for the photovoltaic sheet 4 further includes a storage unit 22 that stores environmental information including at least one of the temperature, humidity, and illuminance of the corresponding storage compartment 13 in association with the storage compartment identification information.

[0080] Because of this configuration, the manager can decide which photovoltaic sheets 4 to ship, taking into account the environmental information for each accommodation section 13.

[0081] Moreover, the management system for the photovoltaic sheet 4 further comprises an environmental information acquisition unit 213 that acquires the detection results by the sensors 12 provided in each of the accommodation compartments 13 as environmental information.

[0082] With this configuration, the environmental information associated with the accommodation section 13 can be automatically acquired.

[0083] The management system for the photovoltaic sheets 4 further includes a shipping priority determination unit 214 that determines the shipping priority of the photovoltaic sheets 4 accommodated in the multiple accommodation sections 13 by using environmental information.

[0084] As configured in this manner, the shipping priority of the photovoltaic sheets 4 is indicated based on the environmental information of the storage area 13, so the user can easily know which photovoltaic sheets 4 should be shipped with priority. In particular, the photovoltaic sheet 4 has a power generation section disposed between a flexible back sheet and a flexible protective sheet overlaid on the back sheet. Since the back sheet and protective sheet contain a large amount of resin material, the photovoltaic sheet 4 is relatively susceptible to deterioration. For this reason, by determining the priority using environmental information, it is possible to know which photovoltaic sheets 4 should be shipped with priority.

[0085] Moreover, in the management system for the solar power generation sheet 4, the reception unit 211 is configured to receive the sheet identification information and the storage section identification information output from the reader 11 that reads the IC tag provided on the solar power generation sheet 4.

[0086] With this configuration, the sheet identification information and the storage section identification information can be easily obtained.

[0087] The management system for the photovoltaic sheet 4 further includes an IC tag that is provided on the photovoltaic sheet 4 and records sheet identification information.

[0088] With this configuration, it is possible to consume the electricity generated by the power generation section of the photovoltaic sheet 4 and obtain a drive current for the IC tag.

[0089] The method for managing the solar power generation sheet 4 includes a step of receiving sheet identification information, which is unique identification information of the solar power generation sheet 4, and a step of associating the sheet identification information of the solar power generation sheet 4 contained in each storage compartment 13 with storage compartment identification information, which is identification information assigned to each of the multiple storage compartments 13.

[0090] Because of this configuration, it is possible to manage the photovoltaic sheets 4 in association with the storage compartments 13 in which the photovoltaic sheets 4 are stored. Therefore, it is possible to manage multiple photovoltaic sheets 4 individually.

[0091] The program according to this embodiment is a program for causing at least one processor to execute each step of the method for managing the photovoltaic sheet 4.

[0092] According to this embodiment, a method for managing the photovoltaic sheet 4 can be realized by executing the program. [Explanation of symbols]
