FIG. 2 is a flowchart for explaining the operation of the information processing device 1 according to one embodiment. The operation of the information processing apparatus 1 according to one embodiment will be described below.

When the information processing apparatus 1 according to one embodiment starts operating, it first acquires information input by the user (steps S1 to S4). Next, the information processing device 1 calculates the self-sufficiency period achieved by each possible combination of the power generation device and the power storage device based on the acquired information (step S5). Then, the information processing device 1 outputs information about a combination that can achieve the self-sufficiency period input by the user (step S6). The information processing apparatus 1 can display the information output in this manner on the display unit 30, for example. The processing performed in each step will be further described below.

In one embodiment, the order of obtaining information in steps S1 to S4 does not matter as long as it is performed before the calculation in step S5. Therefore, the control unit 10 of the information processing device 1 can perform the processes in steps S1 to S4 in any order. Also, the processing in steps S1 to S4 shows a typical representative example. Therefore, at least part of these processes may be omitted, or other processes may be added.

In steps S1 to S4, the control unit 10 may acquire information stored in the storage unit 50, or may acquire information received by the communication unit 40. FIG. In one embodiment, the control unit 10 may acquire information input by the user via the input unit 20 .

Also in this case, the control unit 10 may acquire the stored information from the storage unit 50 as appropriate. As described above, the control unit 10 can perform the processing of steps S1 to S4 in any order. Therefore, in steps S1 to S4, the process of prompting the user to input various kinds of information via the input unit 20 can also be performed in any order. Input of various information by the user described below is merely an example, and the order thereof may be changed as appropriate.

As shown in FIG. 2, when the operation according to one embodiment starts, the control unit 10 of the information processing device 1 acquires information about the power generation device (step S1).

Based on the information acquired in step S1, the control unit 10 calculates the amount of power generated by the power generator. Therefore, when performing the process of step S1, the control unit 10 may prompt the user to input information about a power generation device such as a solar cell.

In photovoltaic power generation, the power generated depends on the location of the installed solar cell (where the solar cell is installed). Therefore, in one embodiment, the information processing device 1 acquires information on the installation location of the user's photovoltaic power generation device. In this case, the control unit 10 may display a screen as shown in FIG. 3 on the display unit 30 to prompt the user to input the installation location of the solar power generation device. The user can input information to the input unit 20 while viewing the display unit 30 on which a screen as shown in FIG. 3 is displayed. The control unit 10 stores information input to the input unit 20 in the storage unit 50 .

FIG. 3 shows a screen on which prefectures and/or districts can be selected in order to specify the installation location of the user's photovoltaic power generation device. Also, as shown in FIG. 3, the installation location of the user's photovoltaic power generation device may be specified by searching from, for example, an address or postal code. Further, as shown in FIG. 3, the GPS function may be used to specify the installation location of the user's photovoltaic power generation device. Further, for example, as shown in FIG. 3, based on the user's input (for example, clicking with a mouse) specifying a position on the map of Japan, the map including the position is displayed so as to be gradually enlarged, so that the user's You may specify the installation place of a solar power generation device. In addition, for example, the amount of power generated by the solar power generation device is calculated based on factors such as whether the installation location of the solar power generation device is shaded during the day (for example, it is in the shadow of a mountain after 15:00). If there is information that is useful for

Here, it is assumed that the storage unit 50 stores a database that associates the locations of installed solar cells with the amount of solar radiation expected at the locations where the solar cells are installed. Thereby, the control part 10 can read the solar radiation amount expected in the said place from the place of the solar cell installed. Then, the control unit 10 can calculate the amount of power generated by the user's photovoltaic power generation device based on the amount of solar radiation. In one embodiment, even if the above-described database is not stored in the storage unit 50, the control unit 10 receives at least part of the above-described database information from an external device or an external server via the communication unit 40. may In this case, an external device or an external server calculates a correction value for the amount of solar radiation due to the terrain around the place where the solar cell is installed, based on a contour map of the place where the solar cell is installed. may be reflected in the information received via

Before displaying the screen shown in FIG. 3, the control unit 10 may display, on the display unit 30, a question such as "Do you have solar cells already installed?" and options of "Yes/No." . When "yes" is selected and input in response to such a question, the control unit 10 may cause the display unit 30 to display an input screen for various information regarding the solar cell as shown in FIG. Further, in this case, the control unit 10 may prompt the user to input or select information such as the manufacturer name and/or model name of the solar cell.

When the input on the screen shown in FIG. 3 is completed, the information processing device 1 can obtain information on the installation location of the user's solar power generation device. When the input on the screen shown in FIG. 3 is completed, the control unit 10 displays the next screen according to the user's input to the "Next" button object on the lower right.

The information input by the user in FIG. 3 may be information on the location where the user currently installs the photovoltaic power generation device (for example, the user's home). On the other hand, the information input by the user in FIG. 3 may be information on the location where the user is currently considering installation of the solar power generation device (for example, the location where the user is considering purchasing such as a house).

As shown in FIG. 3, on each screen, a "next" button object can be displayed at the bottom right, and a "previous" button object can be displayed at the bottom left. In each screen, when a user's input (for example, clicking with a mouse) on the "next" button is detected, the control unit 10 may cause the display to transition to the screen to be displayed next. Similarly, when a user's input (for example, clicking with a mouse) on the "previous" button is detected, the control unit 10 may cause the display to transition to the previously displayed screen.

In addition, in photovoltaic power generation, the amount of power generated depends on the configuration of installed solar cells (what kind of solar cells are installed). Therefore, in one embodiment, the information processing device 1 acquires configuration information of the user's photovoltaic power generation device. In this case, the control unit 10 may display a screen as shown in FIG. 4 on the display unit 30 to prompt the user to input the configuration of the solar power generation device. The user can input information to the input unit 20 while viewing the display unit 30 on which a screen as shown in FIG. 4 is displayed. The control unit 10 stores information input to the input unit 20 in the storage unit 50 .

FIG. 4 shows a screen on which the installation scale (size) of the solar cell module and the corresponding output can be selected in order to specify the configuration of the user's photovoltaic power generation device. FIG. 4 schematically shows a gabled roof of a house viewed obliquely from above. In the screen display examples shown in FIG. 4, the number of constituent solar cell modules is the same, but the number of solar cell elements constituting a single module and the power generation efficiency are different, so the total power generation in each example is different. . In one embodiment, as shown in FIG. 4, the control unit 10 may display radio button objects on the display unit 30 to prompt the user to input a selection. In this case, the control unit 10 detects a user's selection input to the input unit 20 (for example, clicking with a mouse). This allows the user to easily select the installation scale and output of the installed photovoltaic power generation device. Moreover, when the configuration of the user's photovoltaic power generation device is not an option, the control unit 10 may prompt the user to input details of the installation scale (size) and/or output of the photovoltaic power generation device.

Here, it is assumed that the storage unit 50 stores a database in which scales (sizes) of installed solar cells are associated with corresponding outputs. Thereby, the control unit 10 can read the output corresponding to the scale (size) of the installed solar cell. In one embodiment, even if the above-described database is not stored in the storage unit 50, the control unit 10 receives at least part of the above-described database information from an external device or an external server via the communication unit 40. may Alternatively, the information of the size closest to the size of the solar cell may be selected based on user input in an external device or an external server, and the control unit 10 may receive the information via the communication unit 40 .

When the input on the screen shown in FIG. 4 is completed, the information processing device 1 can obtain information on the configuration (installation scale and output) of the user's photovoltaic power generation device. When the input on the screen shown in FIG. 4 is completed, the control unit 10 displays the next screen according to the user's input to the object of the "next" button on the lower right.

The information input by the user in FIG. 4 may be information on the configuration (installation scale and output) of the photovoltaic power generation device currently installed by the user. On the other hand, the information input by the user in FIG. 4 may be information on the configuration (installation scale and output) for which the user is currently considering installation of the photovoltaic power generation device.

Furthermore, in photovoltaic power generation, the power generated is also affected by the installation angle and installation orientation of the solar cell (in what angle and orientation the solar cell is installed). Therefore, in one embodiment, the information processing device 1 acquires information on the installation angle and installation orientation of the user's photovoltaic power generation device. In this case, the control unit 10 may display a screen such as that shown in FIG. The user can input information to the input unit 20 while viewing the display unit 30 on which a screen as shown in FIG. 5 is displayed. The control unit 10 stores information input to the input unit 20 in the storage unit 50 .

FIG. 5 shows a screen on which the user can select the inclination angle and the installation direction (orientation) of the solar cell module in order to specify the installation angle and installation direction of the photovoltaic power generation device. In one embodiment, as shown in FIG. 5, the control unit 10 may display an object on the display unit 30 to prompt the user to input a selection. In this case, the control unit 10 detects a user's selection input to the input unit 20 (for example, clicking with a mouse). This allows the user to easily select the installation angle and installation orientation of the installed photovoltaic power generation device.

In one embodiment, the control unit 10 may display an animated object that moves following the user's operation input on the display unit 30, as shown in FIG. For example, in FIG. 5, the control unit 10 may change the inclination angle of the object of the solar cell module displayed on the display unit 30 by following the user's operation input (for example, dragging with a mouse). In this case, the control unit 10 may use the inclination angle of the object of the solar cell module at the time when the user's drag operation is released as a candidate for the installation angle of the solar cell module. Then, the control unit 10 may change the candidate for the installation angle of the solar cell module again according to the user's operation input (for example, dragging with the mouse). Similarly, for example, in FIG. 5, the control unit 10 may change the orientation of the object of the solar cell module displayed on the display unit 30 by following the user's operation input (for example, dragging with a mouse).

Here, it is assumed that the storage unit 50 stores a database that associates the installation angle and installation direction of the solar cell with the expected amount of solar radiation. Thereby, the control unit 10 can read out the amount of solar radiation expected at the angle and direction from the angle and direction of the installed solar cell. Then, the control unit 10 can calculate the amount of power generated by the user's photovoltaic power generation device based on the amount of solar radiation. In one embodiment, even if the above-described database is not stored in the storage unit 50, the control unit 10 receives at least part of the above-described database information from an external device or an external server via the communication unit 40. may

When the input on the screen shown in FIG. 5 is completed, the information processing device 1 can obtain information on the installation angle and installation orientation of the user's photovoltaic power generation device. When the input on the screen shown in FIG. 5 is completed, the control unit 10 displays the next screen according to the user's input to the object of the "next" button on the lower right.

The information input by the user in FIG. 5 may be information on the installation angle and the installation orientation of the photovoltaic power generation device currently installed by the user. On the other hand, the information input by the user in FIG. 5 may be information on the installation angle and installation direction at which the user is currently considering installation of the photovoltaic power generation device.

As described above, in step S1 (FIG. 2) according to one embodiment, the information of the power generator is acquired. Here, in one embodiment, the power generation device is not limited to a solar power generation device. A case in which a power generation device other than the solar power generation device is considered will be further described later.

As shown in FIG. 2, when the above information is obtained in step S1, the control unit 10 next obtains information about the power storage device (step S2).

Based on the information acquired in step S2, the control unit 10 calculates the amount of power stored (charged) by the power storage device. Therefore, when performing the process of step S2, the control unit 10 may prompt the user to input information regarding a power storage device such as a storage battery (rechargeable battery).

In one embodiment, the information processing device 1 acquires information about the user's storage battery. In this case, the control unit 10 may display a screen as shown in FIG. 6 on the display unit 30 to prompt the user to input information regarding the storage battery. The user can input information to the input unit 20 while viewing the display unit 30 on which a screen as shown in FIG. 6 is displayed. The control unit 10 stores information input to the input unit 20 in the storage unit 50 .

FIG. 6 shows a screen on which the presence or absence of an installed storage battery can be selected in order to specify the installation status of the user's storage battery. In one embodiment, as shown in FIG. 6, the control unit 10 may display a radio button object on the display unit 30 to prompt the user to input a selection. In this case, the control unit 10 detects a user's selection input to the input unit 20 (for example, clicking with a mouse). Thereby, the user can easily select the presence or absence of the installed storage battery.

For example, as shown in FIG. 6, assume that the user selects and inputs "No" in response to the question "Do you have a storage battery already installed?" In this case, the control unit 10 stores the fact in the storage unit 50 assuming that there is no user's storage battery already installed (that is, the storage capacity is zero). Moreover, when the user's storage battery has already been installed, the control unit 10 may prompt the user to input details of the installed storage battery, as shown in FIG. 6 . For example, as shown in FIG. 6, assume that the user selects and inputs "yes" in response to the question "Do you have a storage battery already installed?" In this case, the control unit 10 may cause the display unit 30 to display a screen prompting the user to select or input the storage capacity of the user's storage battery that has already been installed. Then, the control unit 10 stores the power storage capacity of the user's storage battery that has already been installed in the storage unit 50 . Further, in this case, the control unit 10 may prompt the user to input or select information such as the manufacturer name and/or model name of the storage battery.

Here, it is assumed that the storage unit 50 stores a database that associates installed storage batteries with expected storage amounts. Here, the expected power storage amount may be the amount of electric power that is expected to be charged with surplus electric power among the electric power generated by the solar cell. Also, the expected storage amount may be a practical storage capacity in charging and discharging in consideration of the extension of the life of the storage battery. Also, the expected amount of stored electricity may simply be the amount of power output to cover the power supplied to the load. Based on the database described above, the control unit 10 can read out the expected storage amount of the installed storage battery from the storage battery. Then, the control unit 10 can calculate the amount of power output by the user's storage battery based on the amount of stored electricity. In one embodiment, even if the above-described database is not stored in the storage unit 50, the control unit 10 receives at least part of the above-described database information from an external device or an external server via the communication unit 40. may

When the input on the screen shown in FIG. 6 is completed, the information processing device 1 can obtain information on the user's power storage device. When the input on the screen shown in FIG. 6 is completed, the control unit 10 displays the next screen according to the user's input to the "Next" button object on the lower right.

The information input by the user in FIG. 6 may be information on the storage battery currently installed by the user. On the other hand, the information input by the user in FIG. 6 may be information on the storage battery that the user is currently considering installing.

As described above, in step S1 (FIG. 2) according to one embodiment, information on the power storage device is acquired. Here, in one embodiment, the power storage device is not limited to a so-called stationary storage battery. A case of considering a power storage device other than a stationary storage battery will be further described later.

As shown in FIG. 2, when the above information is obtained in step S2, the control unit 10 next obtains information on the state and tendency of power consumption (step S3).

Based on the information acquired in step S3, the control unit 10 calculates power consumption. Therefore, when performing the process of step S3, the control unit 10 may prompt the user to input information regarding the state and tendency of the amount of power consumed by the predetermined load device, for example. Here, the predetermined load device is typically a device installed in the user's home or the like, and may be a device that consumes the amount of power output by the user's power generation device and/or power storage device. The predetermined load device may be a device actually installed in the user's home or the like, or may be a device that is being considered for installation in the user's home. Hereinafter, such load devices as described above will be collectively referred to simply as "user's load devices".

In one embodiment, the information processing apparatus 1 first acquires information about the amount of power consumption of the user's load device as the state of power consumption. In this case, the control unit 10 may display a screen as shown in FIG. 7 on the display unit 30 to prompt the user to input information regarding the power consumption of the load device. The user can input information to the input unit 20 while viewing the display unit 30 on which a screen as shown in FIG. 7 is displayed. The control unit 10 stores information input to the input unit 20 in the storage unit 50 .

FIG. 7 shows a screen on which the state of a house such as the user's house, the user's family structure, and the power consumption of the user's load equipment can be collectively selected in order to specify the power consumption of the user's load equipment. is shown. In one embodiment, as shown in FIG. 7, the control unit 10 may display a radio button object on the display unit 30 to prompt the user to input a selection. In this case, the control unit 10 detects a user's selection input to the input unit 20 (for example, clicking with a mouse). As a result, the user can easily select the situation of the building such as the user's house, the user's family structure, and the power consumption of the user's load equipment all at once.

In FIG. 7, from the viewpoint of lightening the user's operation burden, the building and family structure and the standard power consumption corresponding to the building and family structure are displayed in the same row. Therefore, the user only needs to select the option that most closely matches their situation. On the other hand, in one embodiment, the control unit 10 may specify the power consumption of the user's load equipment in more detail. In this case, the control unit 10 prompts the user to input specific information about at least one of the building conditions of the user's house, the user's family structure, and the power consumption of the user's load equipment. The screen may be displayed on the display unit 30 .

Further, in one embodiment, the information processing apparatus 1 acquires information on the tendency of the power consumption of the user's load equipment. In this case, the control unit 10 may display a screen such as that shown in FIG. The user can input information to the input unit 20 while viewing the display unit 30 on which a screen as shown in FIG. 8 is displayed. The control unit 10 stores information input to the input unit 20 in the storage unit 50 .

FIG. 8 shows a screen on which the user's lifestyle pattern can be selected from the viewpoint of the user's power consumption in order to specify the tendency of the power consumption of the user's load equipment. In one embodiment, as shown in FIG. 7, the control unit 10 may display a radio button object on the display unit 30 to prompt the user to input a selection. In this case, the control unit 10 detects a user's selection input to the input unit 20 (for example, clicking with a mouse). Thereby, the user can easily select the user's lifestyle pattern.

In FIG. 8, from the viewpoint of lightening the user's operational burden, etc., "day type", "night type", and "intermediate type" are displayed so as to be selectable as the user's lifestyle pattern. Therefore, the user only needs to select the option that most closely matches their situation. In FIG. 8, as reference information, a model of the power consumption ratio for each time period is displayed for each life pattern. Here, the “daytime type” may be a life pattern that consumes power even during the daytime, such as a house where a full-time housewife and/or the elderly and/or small children reside. In addition, the “night owl” may be a life pattern that consumes less power during the daytime and consumes power during the nighttime, such as a single-person household, or a house where a double-income couple or a student family resides. Furthermore, the "intermediate type" does not correspond to the typical "day type" or "night type", and may be a life pattern in between these types.

On the other hand, in one embodiment, the control unit 10 may specify the power consumption pattern of the user's load device in more detail. In this case, the control unit 10 may display, on the display unit 30, a screen prompting the user to input a specific ratio of power consumption for each time period, for example.

Furthermore, in one embodiment, the information processing apparatus 1 acquires information on the user's electricity bill as the state and/or tendency of power consumption. In this case, the control unit 10 may display a screen as shown in FIG. 9 on the display unit 30 to prompt the user to input information regarding the electricity bill. The user can input information to the input unit 20 while viewing the display unit 30 on which a screen as shown in FIG. 9 is displayed. The control unit 10 stores information input to the input unit 20 in the storage unit 50 .

FIG. 9 illustrates a screen on which the user's electricity bill can be entered to identify the power consumption status and/or trend of the user's load equipment. FIG. 9 shows a screen on which a contracted power company, power plan, etc., can be selected in order to specify the user's power rate. In one embodiment, the control unit 10 may display a radio button object on the display unit 30 to prompt the user to input a selection, as shown in FIG. In this case, the control unit 10 detects a user's selection input to the input unit 20 (for example, clicking with a mouse). Thereby, the user can easily select the input mode of the electricity bill.

In FIG. 9, from the viewpoint of lightening the user's operation burden, etc., an input for simple calculation with one month's power rate is displayed so as to be selectable. Therefore, the user only needs to enter a typical electricity bill for one month. In this case, the control unit 10 stores the monthly power bill and stores the monthly power bill multiplied by 12 as the annual power bill. On the other hand, in one embodiment, the control unit 10 may specify the user's power rate in more detail. In this case, the control unit 10 may display, on the display unit 30, a screen prompting the user to enter the power rate for each month from January to December, as shown in FIG.

When the inputs on the screens shown in FIGS. 7 to 9 are completed, the information processing apparatus 1 can obtain information on the user's power consumption status and trends. When the input on the screens shown in FIGS. 7 to 9 is completed, the control unit 10 displays the next screen according to the user's input to the object of the "next" button on the lower right.

The information input by the user in FIGS. 7 to 9 may be information based on the load equipment currently installed by the user. On the other hand, the information input by the user in FIGS. 7 to 9 may be information based on the load equipment that the user is currently considering installing.

As described above, in step S3 (FIG. 2) according to one embodiment, the power consumption status and trend information is acquired.

As shown in FIG. 2, when the above information is obtained in step S3, the control unit 10 next obtains information about the self-sufficiency period input by the user (step S4).

Based on the information acquired in step S4, the control unit 10 sets the self-sufficiency period. Therefore, when performing the process of step S4, the control unit 10 may prompt the user to input information regarding the self-sufficiency period.

In one embodiment, the information processing device 1 acquires information about the self-sufficiency period desired by the user. In this case, the control unit 10 may display screens as shown in FIGS. 10A and 10B on the display unit 30 to prompt the user to input information regarding the self-sufficiency period desired by the user. The user can input information to the input unit 20 while viewing the display unit 30 on which screens as shown in FIGS. 10A and 10B are displayed. The control unit 10 stores information input to the input unit 20 in the storage unit 50 .

In one embodiment, the self-sufficiency period may be a period during which power is self-sufficient. That is, the self-sufficiency period can be defined as a period during which power consumption can be covered by power output from the user's power generation device and/or power storage device without purchasing power from the grid. In one embodiment, the self-sufficiency period may be more specific, such as "self-sufficiency days" or "self-sufficiency rate". Here, the number of self-sufficiency days is the self-sufficiency period expressed in days. For example, a self-sufficiency period of “3 days” means that power consumption can be covered by power output from the user's power generation device and/or power storage device for 3 days without purchasing power from the grid. means. Also, the self-sufficiency period of "three days" does not necessarily have to be continuous time. For example, a self-sufficiency period of "total of 3 days" may be obtained by having three self-sufficient "1 days" in a predetermined period (typically 365 days). Also, the self-sufficiency rate is expressed as a ratio of the self-sufficiency period to a predetermined period (for example, 365 days). For example, if the self-sufficiency rate is "2%" when the predetermined period is 365 days, power is not purchased from the grid for 7.3 days and is output from the user's power generation device and/or power storage device. Power means that power consumption can be covered. Also in this case, "7.3 days" does not necessarily have to be continuous time. For example, during a predetermined period (typically 365 days = 8760 hours), self-sufficient "1 hour (for example, when the minimum unit is 1 hour)" is 176 times (calculated 175.2 times as the minimum unit (summarized in ) may be a self-sufficiency period of “total 176 hours” due to existence.

FIG. 10A shows a screen on which the user can select whether to input the self-sufficiency period as "self-sufficiency days" or "self-sufficiency rate" in order to specify the self-sufficiency period desired by the user. In one embodiment, the control unit 10 may display a radio button object on the display unit 30 to prompt the user to input a selection, as shown in FIG. 10A. In this case, the control unit 10 detects a user's selection input to the input unit 20 (for example, clicking with a mouse). This allows the user to easily select the mode of input of the self-sufficiency period.

For example, as shown in FIG. 10A , when the user selects input of “number of self-sufficiency days”, the control unit 10 displays on the display unit 30 a screen prompting the user to input the numerical value of the number of self-sufficiency days. good. Further, when the input of the "self-sufficiency rate" desired by the user is selected, the control unit 10 may display on the display unit 30 a screen prompting the user to input the numerical value of the self-sufficiency rate. As described above, in the information processing apparatus 1 according to one embodiment, the user can specify his or her desired self-sufficiency period.

In one embodiment, as shown in FIG. 10A, the display unit 30 may display a screen for setting the number of days that serve as a reference for the self-sufficiency period. In the example shown in FIG. 10A, the self-sufficiency period criterion is set to 365 days by default. In this case, the control unit 10 may change the standard number of days of the self-sufficiency period from 365 days according to the user's input. For example, the user may set the reference number of days for the self-sufficiency period to a specific period such as a specific summer or winter.

Next, in one embodiment, as shown in FIG. 10B , the control unit 10 may display on the display unit 30 a screen on which the definition of the number of self-sufficiency days per day can be set. In one embodiment, the control unit 10 may display a radio button object on the display unit 30 to prompt the user to input a selection, as shown in FIG. 10B. In this case, the control unit 10 detects a user's selection input to the input unit 20 (for example, clicking with a mouse). This allows the user to easily select whether or not to define the self-sufficiency period for one day as 24 hours.

In the example shown in FIG. 10B, the definition of one day of self-sufficiency days is set to 24 hours as a default. However, the number of self-sufficient days desired by the user is not necessarily limited to 24 hours. For example, in the case of a single user, there are cases where he/she wishes to consider the number of self-sufficient days only during the nighttime period during which the user lives at home. In addition, for example, in the case of a user who wants to consider the self-sufficiency period of a building of a medical institution, etc., the user may wish to consider the number of self-sufficiency days that can handle up to twice the power consumption in an emergency, with a unit of 48 hours per day. be. Therefore, in one embodiment, as shown in FIG. 10B, the control unit 10 may define the number of self-sufficient days so that the number of hours per day is set to other than 24 hours. Furthermore, in one embodiment, as shown in FIG. 10B , the control unit 10 may also be able to set a time period when the number of self-sufficient days is set to a day other than 24 hours. As described above, according to the information processing apparatus 1 according to one embodiment, it is possible to consider introducing or changing a power generation device and/or a power storage device based on the self-sufficiency period or number of days that suits the practical purpose of each user. can be done. Also, when the user selects the input of the "self-sufficiency rate" desired by the user on the screen shown in FIG. 10A, as shown in FIG. It may be configurable.

When the input on the screens shown in FIGS. 10A and 10B is completed, the information processing apparatus 1 can obtain information on the self-sufficiency period desired by the user. When the input on the screens shown in FIGS. 10A and 10B is completed, the control unit 10 displays the next screen according to the user's input to the object of the "next" button on the lower right.

As shown in FIG. 2, when the above information is acquired in step S4, the control unit 10 next calculates a combination that can achieve the self-sufficiency period (step S5).

In step S5, the control unit 10 calculates the self-sufficiency period achieved by each combination of the power generation device and the power storage device based on the information obtained in steps S1 to S3. In one embodiment, each combination of the power generation device and the power storage device may be each of the possible combinations of the power generation device and the power storage device. Specifically, in one embodiment, each combination of the power generation device and the power storage device may be a combination in which the power generated by the power generation device and the power storage capacity of the power storage device are used as respective elements.

Next, processing for calculating the self-sufficiency period achieved by each combination of the power generation device and the power storage device in the information processing device 1 according to one embodiment will be described. First, the case of calculating the self-sufficiency period as the number of self-sufficiency days will be described.

FIG. 11 is a flowchart showing a process of calculating the number of days of self-sufficiency achieved by one of the combinations when calculating the self-sufficiency period achieved by each combination of the power generation device and the power storage device. A process of calculating the number of days of self-sufficiency achieved by one of the combinations of the power generation device and the power storage device, which is performed by the control unit 10, will be described below.

When the process shown in FIG. 11 is started, the control unit 10 acquires the definition of one day of self-sufficiency days (step S11). In step S<b>11 , the control unit 10 may read from the storage unit 50 the information on the self-supply period acquired in step S<b>4 shown in FIG. 2 . The definition of one day of self-sufficiency days acquired in step S11 may be defined as the definition of the time constituting one day of self-sufficiency days desired by the user. In addition, if the definition of the self-sufficiency days acquired in step S11 is not 24 hours, the definition may be a time zone of hours constituting a day.

After the definition of one day is acquired in step S11, the control unit 10 acquires the power consumption (kWh) (1) of the user's load equipment (step S12). In step S<b>12 , the control unit 10 may read from the storage unit 50 information on the state and tendency of power consumption acquired in step S<b>3 shown in FIG. 2 . Then, the control unit 10 acquires the power consumption of the load device of the user in units of time such as a predetermined 30 minutes on the time axis.

When the power consumption of the load is acquired in step S12, the control unit 10 calculates the power consumption (kWh) (2) of the load covered by the power generator (step S13). In step S13, the control unit 10 may read from the storage unit 50 the information on the power consumption of the user's load equipment acquired in step S12 and the information on the power generator acquired in step S1 shown in FIG. Then, based on the acquired information, the control unit 10 determines that the electric power consumption of the user's load equipment is covered by the power generation device such as the solar battery in a predetermined time unit such as 30 minutes on the time axis. Calculate the amount of power consumed.

After the power consumption covered by the power generation device is calculated in step S13, the control unit 10 calculates the power consumption (kWh) (3) of the load covered by the power storage device (step S14). In step S<b>14 , the control unit 10 may read from the storage unit 50 the information on the power consumption of the user's load device acquired in step S<b>12 and the information on the power storage device acquired in step S<b>2 shown in FIG. 2 . Then, based on the acquired information, the control unit 10 determines whether the power consumption of the user's load device is covered by the power storage device such as the storage battery in a time unit such as a predetermined 30 minutes on the time axis. Calculate the amount of power.

After the power consumption of the load covered by the power storage device is calculated in step S14, the control unit 10 determines whether or not self-supply of power is possible in one day defined in step S11 (step S15). In step S15, the control unit 10 converts the power consumption (2) of the load covered by the power generation device, which is acquired in units of time such as a predetermined 30 minutes on the time axis, to Add time only. Similarly, in step S15, the control unit 10 acquires the power consumption (3) of the load covered by the above-described power storage device, which is acquired in units of time such as a predetermined 30 minutes on the time axis, as defined in step S11. Add only hours in a day. Similarly, in step S15, the control unit 10 also calculates the power consumption (1) of the user's load device, which is obtained in units of time such as a predetermined 30 minutes on the time axis, for one day defined in step S11. add only the time of Then, in step S15, if the sum of power consumption (2) and power consumption (3) reaches the value of power consumption (1), the control unit 10 is self-sufficient in power for the day. is possible. In this case, for example, the result of subtracting the power consumption of the load covered by the power generation device in one day and the power consumption of the load covered by the power storage device in one day from the power consumption of the load equipment in one day is positive. If the value of

If it is determined in step S15 that self-sufficiency of power for one day is possible, the control unit 10 adds one day (plus one day) to the number of days of self-sufficiency (step S16).

After adding the self-sufficient days in step S16, the control unit 10 determines whether or not the calculations from step S12 to step 16 have been performed for the number of self-sufficient days in a predetermined period (step S17). In step S17, the control unit 10 may determine whether or not the calculations from step S12 to step 16 have been performed for the reference period (see FIG. 10A) such as 365 days set in step S4 (FIG. 2). .

On the other hand, if it is determined in step S15 that self-sufficiency of electric power for one day is not possible, the control unit 10 does not add one day to the number of self-sufficient days, skips the processing of step S16, and performs the processing of step S17.

If the self-sufficiency days in the predetermined period have not been calculated in step S17, the control unit 10 returns to step S12 and repeats the process. On the other hand, when the calculation of the self-sufficiency days in the predetermined period is performed in step S17, the control unit 10 outputs the information of the self-sufficiency days to, for example, the storage unit 50 (step S18), and performs the processing shown in FIG. finish. When the processing up to step S18 is performed, the control unit 10 can output information regarding the number of days of self-sufficiency achieved by one of the combinations of the power generation device and the power storage device from the given information.

Here, when there are a plurality of possible combinations of the power generation device and the power storage device, by performing the processing shown in FIG. 11 for each combination, the self-sufficiency period (self-sufficiency days) achieved by each combination can be calculated.

Further, each possible combination of the power generation device and the power storage device may be set based on various information acquired in steps S1 to S3 shown in FIG. For example, the combination of the power generation device and the power storage device may be all possible combinations of options for the generated power of the power generation device and options for the storage capacity of the power storage device. For example, assume that 12 options are assumed for the power generated by the power generation device and 3 options are assumed for the power storage capacity of the power storage device. In this case, there are a total of 36 combinations of power generation devices and power storage devices. In this case, the control unit 10 may calculate the self-sufficiency period (self-sufficiency days or self-sufficiency rate) to be achieved by performing the processing of FIG. 11 or 12 for each of the 36 combinations of the power generation device and the power storage device. .

In addition, for example, the combination of the power generation device and the power storage device is a limited combination based on the user's input, out of all possible combinations of the options for the generated power of the power generation device and the options for the storage capacity of the power storage device. good too. For example, the power generated by the power generation device that the user has already installed or is considering installation is limited to 4 options, and the power storage capacity of the power storage device that the user has already installed or is considering installation is 2. is limited to the options of In this case, there are a total of eight combinations of power generation devices and power storage devices. In this case, the control unit 10 may perform the processing of FIG. 11 or FIG. 12 for each of the eight combinations of the power generation device and the power storage device to calculate the achievable self-sufficiency period (self-sufficiency days or self-sufficiency rate). .

In the example described in FIG. 11, the self-sufficiency days were calculated in units of 30 minutes on the time axis. However, the length of time used to calculate the self-sufficiency days is arbitrary. For example, if the processing capacity of the control unit 10 and/or the storage capacity of the storage unit 50 is sufficient, the self-sufficiency days may be calculated more accurately in units of 10 minutes on the time axis. Further, for example, in order to shorten the calculation time by the control unit 10, the self-sufficiency days may be calculated in units of one hour on the time axis.

Next, a case of calculating the self-sufficiency period as the self-sufficiency rate will be described.

FIG. 12 is a flowchart showing the process of calculating the self-sufficiency rate achieved by one of the combinations when calculating the self-sufficiency period achieved by each combination of the power generation device and the power storage device, as in FIG. A process of calculating the self-sufficiency rate achieved by one of the combinations of the power generation device and the power storage device in a predetermined period, which is performed by the control unit 10, will be described below.

Since the processing from step S11 to step S14 shown in FIG. 12 is the same as that explained with reference to FIG. 11, a more detailed explanation will be omitted.

After the processing up to step S14 has been performed, next, the control unit 10 performs the processing of step S25 shown in FIG. 12 as follows. In step S25, the control unit 10 calculates the sum of the power consumption amount (2) of the load covered by the power generation device and the power consumption amount (3) of the load covered by the power storage device (that is, (2)+ (3)) is added every predetermined time. In step S25, the control unit 10 also adds the power consumption (1) of the user's load device at predetermined time intervals. Here, for the above (2)+(3) and the above (1), the predetermined time for each addition is, for example, the above (1) to (3) are obtained in the same manner as the above-described predetermined time. It may be a predetermined time unit such as 30 minutes on the time axis.

After the addition is performed in step S25, the control unit 10 determines whether or not the addition has been performed for the time of one day (see FIG. 10B) acquired in step S11 (step S26). That is, in step S26, the control unit 10 determines whether or not the addition process in step S25 has been performed for the defined "one day". If it is determined in step S26 that one day's worth has not been added, the control unit 10 returns to step S12 and repeats the process.

On the other hand, when it is determined in step S26 that one day's worth of addition has been performed, the control unit 10 determines whether or not the calculation in step S26 has been performed for a predetermined period (step S27). In step S27, the control unit 10 may determine whether or not the calculation in step S26 has been performed for the reference period (see FIG. 10A) such as 365 days set in step S4 (FIG. 2).

If the calculation has not been performed for the predetermined period in step S27, the control unit 10 returns to step S22 and repeats the process. On the other hand, when the calculation is performed for the predetermined period in step S27, the control unit 10 calculates the self-sufficiency rate (step S28).

In step S28, the control unit 10 can calculate the self-sufficiency rate based on the information calculated in steps S25 to S27, for example. Specifically, the self-sufficiency rate is obtained by dividing the above value ((2)+(3)) added for a predetermined period in step S27 by the above value (1) added for a predetermined period in step S27. , 100.

After the self-sufficiency rate is calculated in step S28, the control unit 10 outputs information on the self-sufficiency rate to, for example, the storage unit 50 (step S29), and ends the processing shown in FIG. When the processing up to step S29 is performed, the control unit 10 can output information about the self-sufficiency rate that one of the combinations of the power generation device and the power storage device can achieve in a predetermined period from the given information.

Here, when there are a plurality of possible combinations of the power generation device and the power storage device, the self-sufficiency rate achieved by each combination can be calculated by performing the processing shown in FIG. 12 for each combination.

Further, each possible combination of the power generation device and the power storage device may be set based on the various information acquired in steps S1 to S3 shown in FIG. 2, as explained in FIG. be.

In the example described in FIG. 12, the self-sufficiency rate was calculated in units of 30 minutes on the time axis. However, the length of time used to calculate the self-sufficiency rate is arbitrary. For example, the self-sufficiency rate may be calculated in units of 10 minutes on the time axis, or may be calculated in units of 1 hour on the time axis.

As shown in FIG. 2, when the self-sufficiency period achieved by each combination is calculated in step S5, the control unit 10 next outputs information about the combinations that can achieve the self-sufficiency period input by the user (step S6).

FIG. 13 is a flowchart for explaining in more detail the process of outputting information on a combination that can achieve the self-sufficiency period input by the user, which is performed in step S6 shown in FIG. An example in which the self-sufficiency period is set to the number of self-sufficiency days will be described below, but the self-sufficiency rate can also be used as the self-sufficiency period by replacing the "number of days" with the "rate" in the following description.

When the process shown in FIG. 13 starts, the control unit 10 first performs the process of step S31. In step S31, the control unit 10 determines that the number of days of self-sufficiency (calculated in step S5) achieved by one of the combinations of the power generation device and the power storage device is equal to or greater than the number of days of self-sufficiency (obtained in step S4) input by the user. or not. One of the combinations of the power generation device and the power storage device determined in step S31 may be one selected from the combinations of the power generation device and the power storage device for which the self-sufficiency days were calculated in step S5. In one embodiment, one combination determined in step S31 may be selected in order from among (a plurality of) combinations of the power generation device and the power storage device for which the self-sufficiency days have been calculated in step S5.

If the number of days of self-sufficiency achieved by one combination is equal to or greater than the number of days of self-sufficiency input by the user in step S31, the control unit 10 performs the process of step S32. In step S32, the control unit 10 outputs information about the one combination in a form indicating that the number of self-sufficiency days input by the user is achievable (hereinafter referred to as "a form indicating achievability" as appropriate). (Step S32). In step S32, the mode indicating achievability can be various modes. For example, the aspect indicating achievable may be an aspect in which the information about the one combination is displayed together with characters indicating that the number of self-sufficiency days input by the user is achievable. Also, the aspect of indicating achievability may be, for example, an aspect in which information about one combination is displayed in a color-coded manner or surrounded by a frame so as to be distinguishable from others. Typically, the aspect indicating achievable may be an aspect displayed so as to be distinguishable from information relating to combinations that cannot achieve the number of self-sufficiency days input by the user.

After the process of step S32 is performed, the control section 10 performs the process of step S33. On the other hand, if the number of days of self-sufficiency achieved by one combination is not equal to or greater than the number of days of self-sufficiency input by the user in step S31, the control unit 10 skips the processing of step S32 and performs the processing of step S33.

In step S33, the control unit 10 determines whether or not the determination process of step S31 has been performed for all combinations of the power generation device and the power storage device for which the self-sufficiency days have been calculated in step S5. If determination processing has not yet been performed for all combinations in step S33, the control unit 10 returns to step S31 to continue processing. When returning to step S31, the control unit 10 determines whether or not the number of days of self-sufficiency is equal to or greater than the number of days of self-sufficiency input by the user for one of the combinations for which the determination processing of step S31 has not yet been performed. good.

On the other hand, if determination processing has been performed for all combinations in step S33, the control unit 10 ends the processing shown in FIG. Through such processing, the control unit 10 can output information about a combination that can achieve the self-sufficiency period input by the user.

In step S6 shown in FIG. 2, the control unit 10 causes the display unit to display various types of information, including information on the combination of the power generation device and the power storage device that can achieve the self-sufficiency period input by the user, based on the calculation in step S5. 30 may be displayed. For example, the simplest information is information on whether or not it is possible to achieve the self-sufficiency period desired by the user in the combination of the power generation device and the power storage device input or selected by the user based on the information input by the user. may be presented only.

Further, for example, in the operation shown in FIG. 2, by changing at least one of the power generation device information acquired in step S1 and the power storage device information acquired in step S2, the achievable self-sufficiency period changes. Therefore, in step S5, the control unit 10 also calculates the combination of the power generation device and the power storage device that achieves self-sufficiency for a period with a predetermined width in the self-sufficiency period, including the self-sufficiency period desired by the user. You can leave it. For example, generally, when at least one of the power generation device and the power storage device is added, the self-sufficiency period also increases. Moreover, generally, when the number of installations of at least one of the power generation device and the power storage device is reduced, the self-sufficiency period is also reduced. In this way, information including a combination of a power generation device and a power storage device that achieves self-sufficiency for a period with a predetermined width in the self-sufficiency period desired by the user can be useful information for the user. Therefore, in step S6, the control unit 10 may also output information on the combination of the power generation device and the power storage device that achieves self-sufficiency for a period with a predetermined width in the self-sufficiency period desired by the user.

Next, an example of displaying the information output in step S6 of FIG. 2 on the display unit 30 will be described.

FIG. 14 is a diagram showing an example of the information output in step S6 of FIG. 2 displayed on the display unit 30. As shown in FIG.

FIG. 14 is a diagram showing an example of the number of self-sufficient days achieved when the number of user's storage batteries (storage capacity) is fixed and the installation capacity (generated power) of solar cells is variable. In the example shown in FIG. 14, for example, the user skips the input of the solar battery information shown in FIGS. 4 and 5, and inputs only one storage battery information (storage capacity 6.5 kWh) shown in FIG. , may be displayed when the input of self-sufficiency days shown in FIG. 10A is also skipped. That is, the example shown in FIG. 14 shows how many days of self-sufficiency can be achieved when the user installs only one storage battery and installs or expands the number of solar cells. For example, as shown in FIG. 14, even if a 1 kW solar battery is installed with the user's storage battery installed, the number of self-sufficient days will be zero, but if a 2 kW solar battery is installed, the number of self-sufficient days will be 18 days. . Also, as shown in FIG. 14, if a 10 kW solar battery is installed while the user's storage battery is installed, the self-sufficiency days will be 136 days.

Here, in the number of self-sufficient days shown in FIG. 14, the user can freely set the definition of one day (the number of hours in one day from what time to what time). Moreover, in calculating the number of self-sufficient days, the reference period can be one year such as 365 days, or can be any period other than 365 days. Further, for example, in calculating the self-sufficiency days, the reference period may be a specific period such as summer or winter. Further, in FIG. 14, each output value of the solar cell may be associated with information such as the number of solar cell modules and presented to the user at the same time.

FIG. 15 is a diagram showing another example of displaying the information output in step S6 of FIG.

FIG. 15 is a diagram showing an example of self-sufficiency days achieved when the power storage capacity (for example, number) of the user's storage battery is variable between three values, and the installed capacity (generated power) of the solar battery is also variable from 5 kW. is. Here, the installed capacity (power generation) of the solar cell may be, for example, the power generation capacity of the solar cell (for example, the number of solar cell modules). In the example shown in FIG. 15, for example, the user selects and inputs 5 kW as the solar battery information shown in FIG. 4, selects and inputs "No" for installation of the storage battery shown in FIG. It may be displayed when the input of self-sufficiency days is also skipped. That is, the example shown in FIG. 15 summarizes how many days of self-sufficiency can be achieved when the user installs (or considers installing) storage batteries of three types of capacity and installs a 5 kW solar battery. there is

For example, as shown in FIG. 15, when a 3.2 kWh storage battery is installed, even if a 5 kW solar battery is installed, the number of self-sufficient days is zero. becomes. For example, as shown in FIG. 15, if a 5 kW solar battery is installed with a 6.5 kWh storage battery installed, the number of self-sufficient days is 97 days, but if the solar battery is increased to 6 kW, the number of self-sufficient days is 115 days. becomes. For example, as shown in FIG. 15, if a 12 kWh storage battery is installed, the self-sufficiency days will be 250 days if a 5 kW solar battery is installed.

In the self-sufficiency days shown in FIG. 15 as well, the definition of one day and the reference period can be freely set by the user. Further, as shown in FIG. 15, the control unit 10 may display on the display unit 30, for example, different colors depending on whether the solar cell is not added or when the solar cell is added. For example, assume that the user currently has a 5 kW solar battery installed and is considering introducing a new storage battery. At this time, the user can easily recognize the difference in the achievable self-sufficiency period between using the solar battery as it is and when adding or changing the solar battery from the information shown in FIG. .

When introducing or increasing the number of solar cells, it is assumed that there is an upper limit to the number of solar cell modules that can be installed, for example, on the roof of a house. Therefore, if the upper limit of the number of installable solar cell modules or the like can be grasped in advance, the control unit 10 may prevent the display unit 30 from displaying a combination that exceeds the upper limit. For example, there is a limit to the number of solar cell modules that can be installed on the roof of a house or the like, and it is conceivable that the power generated by the solar cell is limited to 10 kW. In such a case, as shown in FIG. 15, the control unit 10 may not output information regarding combinations in which the power generated by the solar cells exceeds 10 kW. In FIG. 15, as a result of not outputting information on combinations in which the generated power of the solar cells exceeds 10 kW, information on combinations in which the generated power of the solar cells exceeds 10 kW is shown in blanks.

In addition, information such as that shown in FIG. 15 may be presented including how the current electricity rate changes in each case. As a result, the user can obtain effective judgment material from an economical point of view.

FIG. 16 is a diagram showing another example of displaying the information output in step S6 of FIG.

FIG. 16 is a diagram showing an example of self-sufficiency days achieved when the power storage capacity (for example, the number) of the user's storage battery is variable between three values, and the installed capacity (power generation amount) of the solar battery is also variable. In the example shown in FIG. 16, for example, the user skips the input of the solar battery information shown in FIGS. 4 and 5, selects and inputs "No" for installation of the storage battery shown in FIG. It may be displayed when the self-sufficiency days are input as 250 days. That is, in the example shown in FIG. 16, the user installs (or considers installing) storage batteries with three types of capacities, and further shows what kind of solar battery to install to achieve 250 days of self-sufficiency. ing.

For example, as shown in FIG. 16, in a state where a 3.2 kWh storage battery is installed, even if a solar battery of up to 15 kW is installed, the self-sufficiency days will not reach 250 days. Further, as shown in FIG. 16, even if a 6.5 kWh storage battery is installed, even if a solar battery of up to 15 kW is installed, the self-sufficiency days will not reach 250 days. On the other hand, as shown in FIG. 16, when a 12 kWh storage battery is installed, the self-sufficiency days will not reach 250 days even if the solar battery is installed up to 4 kW, but if the solar battery is installed at 5 kW or more, the self-sufficient days will be 250 days. can be achieved. Moreover, as shown in FIG. 16, if a solar battery of 6 kW or more is installed in a state where a 12 kWh storage battery is installed, the self-sufficiency days exceeding 250 days can be increased.

In the self-sufficiency days shown in FIG. 16 as well, the definition of one day and the reference period can be freely set by the user. Further, as shown in FIG. 16, the control unit 10 distinguishes the information on the combination of the solar battery and the storage battery that achieves the self-sufficiency period desired by the user by, for example, color-coding or framing the information. You may display on the display part 30 so that it can distinguish. For example, in FIG. 16, when the self-sufficiency period desired by the user is input as 250 days, the information portion of the combination achieving the self-sufficiency period of 250 days is enclosed in a thick frame. This allows the user to easily grasp that a 5 kW solar battery and a 12 kWh storage battery should be installed in order to achieve a self-sufficiency period of 250 days. In addition, the user can easily grasp how much output of the solar battery should be installed together with the 12 kWh storage battery in order to achieve a self-sufficiency period of more than 250 days.

FIG. 17 is a diagram showing another example of displaying the information output in step S6 of FIG.

FIG. 17 is achieved when the storage capacity (for example, number) of the user's storage battery is variable in three values, and the installed capacity (power generation amount) of the solar battery is also variable, similar to the example shown in FIG. It is a figure which shows the example of self-sufficiency days. The example shown in FIG. 17 shows the self-sufficiency period under a different situation from the example shown in FIG. Therefore, in the example shown in FIG. 17, the self-sufficiency period achievable by each combination of solar cells and storage batteries may differ from the example shown in FIG.

In the example shown in FIG. 17, for example, the user skips the input of the solar battery information shown in FIGS. 4 and 5, selects and inputs "No" for installation of the storage battery shown in FIG. It may be displayed when the self-sufficiency days are input as 300 days. That is, in the example shown in FIG. 17, the user installs (or considers installing) storage batteries with three types of capacities, and further indicates what kind of solar battery should be installed to achieve 300 days of self-sufficiency. ing.

For example, as shown in FIG. 17, when a 12 kWh storage battery is installed, even if the solar battery is installed up to 4 kW, the self-sufficient days will not reach 300 days. can be achieved.

In addition, as shown in FIG. 17, the control unit 10 distinguishes the price range of the cost required for the combination of the solar battery and the storage battery to achieve the number of days paid for each individual by, for example, color-coding or enclosing it with a frame. You may display on the display part 30 so that it may be possible. For example, in FIG. 17, the price range of the cost required for the combination of the solar battery and the storage battery that achieves the number of days paid for each person is shown in different colors in units of 1,000,000 yen. This allows the user to get an overview of the costs required for the combination of solar cells and storage batteries to achieve each pay period. As a result, the user can obtain effective judgment material from an economical point of view.

As described above, according to the information processing apparatus 1 according to one embodiment, it is possible to present a combination of a power generation device and a power storage device from the viewpoint of a self-sufficiency period such as the number of self-sufficiency days of electric power. Therefore, the user can obtain effective judgment materials when making a decision about introduction or change of the power generation device and/or the power storage device. Therefore, according to the information processing device 1 according to one embodiment, convenience can be improved.

Here, it is conceivable that the self-sufficiency period desired by the user cannot be achieved, regardless of the combination of the power generation device and the power storage device input by the user, for example. In such a case, the control unit 10 may present information to the user by outputting information on power consumption that should be reduced in order to achieve the self-sufficiency period desired by the user. Further, the control unit 10 may control the power of the user's load equipment by controlling, for example, HEMS (Home Energy Management System) according to the information presented in this way.

Further, in the above-described embodiments, the description has been given mainly assuming that the power generating device that requests the user to input information is a solar battery or the like. However, the information of the power generation device that can be processed by the information processing device 1 according to one embodiment is not limited to the solar cell. For example, in one embodiment, the information on the power generator processed by the information processing device 1 may be information on the power generator that performs hydraulic power generation, wind power generation, or the like. In recent years, some ordinary households have installed small-scale hydroelectric or wind power generation facilities. Therefore, in such a home, the accuracy of the calculation result performed by the control unit 10 can be improved by also considering the amount of power output by the already installed hydroelectric power generation or wind power generation equipment. In addition, installation of small-scale hydroelectric or wind power generation facilities is not limited to general households. For example, even in public facilities such as public halls where small-scale communities gather, there are cases where small-scale hydroelectric or wind power generation facilities are installed.

FIG. 18 is a diagram showing another example of displaying the information output in step S6 of FIG.

In FIG. 18, in the same scene as the example shown in FIG. 17, information about the combination corresponding to the self-sufficiency period closest to the user's input among the combinations that can achieve the self-sufficiency period input by the user is conspicuously displayed. FIG. 4 is a diagram showing an example;

Similar to the example shown in FIG. 17, the example shown in FIG. 18 may be displayed when 300 days are entered as the number of self-sufficient days shown in FIG. 10A. That is, in the example shown in FIG. 18, similar to the example shown in FIG. It shows whether it is possible to achieve the number of self-sufficient days.

Here, as shown in FIG. 18, the control unit 10 distinguishes the information on the combination corresponding to the self-sufficiency period closest to the user's input by, for example, coloring it or enclosing it with a frame. It may be displayed on the display unit 30 . For example, in FIG. 18, information (display of 300 days) on the combination corresponding to the closest self-sufficiency period of 300 days to the user-inputted combination that can achieve the self-sufficient period of 300 days is conspicuously displayed. It is With such a display, the user can easily grasp at a glance that a combination of a 5 kW solar cell and a 12 kWh storage battery should be installed in order to achieve a self-sufficiency period of 300 days.

Also, for example, in FIG. 18, assume that the self-sufficiency period input by the user is 220 days. In this case, the control unit 10 makes the information (display of 228 days) about the combination corresponding to the self-sufficiency period of 228 days, which is the closest to the user's input (220 days), out of the combinations that can achieve the self-sufficiency period of 220 days. may be displayed on With such a display, the user can easily understand at a glance that a combination of a 4 kW solar cell and a 12 kWh storage battery should be installed in order to achieve a self-sufficiency period of 228 days.

As described above, according to the information processing apparatus 1 according to one embodiment, it is possible to easily grasp the combination closest to the user's request at a glance, among the combinations of the power generation device and the power storage device. Therefore, according to the information processing apparatus 1 according to one embodiment, it is possible to further improve convenience.

FIG. 19 is a diagram showing still another example of displaying the information output in step S6 of FIG.

FIG. 19 also shows an example in which information about the combination corresponding to the self-sufficiency period closest to the user's input, among the combinations that can achieve the self-sufficiency period input by the user, is conspicuously displayed. Here, the example shown in FIG. 19 may also be displayed when the number of self-sufficient days shown in FIG. 10A is input as 300 days. That is, in the example shown in FIG. 19 as well, the user installs (or considers installing) storage batteries with three types of capacities, and further shows what kind of solar battery to install to achieve 300 days of self-sufficiency. ing.

Similarly to the example shown in FIG. 18, FIG. 19 also shows an example of outputting information suggesting a combination corresponding to the self-sufficiency period closest to the user's input among the combinations that can achieve the self-sufficiency period input by the user. is shown. That is, in FIG. 19 as well, information (display of 300 days) on the combination corresponding to the closest self-sufficiency period of 300 days to the user-inputted combination among the combinations capable of achieving the self-sufficient period of 300 days is conspicuously displayed. It is

Furthermore, in one embodiment, as shown in FIG. 19, the control unit 10 may also output information suggesting a combination corresponding to the self-sufficiency period with a predetermined width in the self-sufficiency period input by the user. That is, in FIG. 19, information (display of 250 days to 325 days) corresponding to the self-sufficiency period (250 days to 350 days) with a range of ±50 days for the self-sufficiency period of 300 days input by the user. are also displayed so as to be distinguishable from other displays. With such a display, the user can easily understand at a glance not only the combination that can achieve the self-sufficiency period of 300 days, but also information on the peripheral combinations.

Such information suggesting a combination corresponding to the self-sufficiency period with a predetermined width in the self-sufficiency period input by the user may be set to be displayed by default. Information suggesting a combination corresponding to the self-sufficiency period with a predetermined range is displayed after prompting the user to input the predetermined range (plus or minus how many days) in advance. may Further, the predetermined width of the self-sufficiency period is not limited to plus or minus how many days, and may be a width in which the upper limit and/or the lower limit can be freely set.

Next, the specification for improving the accuracy of the calculation result performed in step S5 of FIG. 2 will be further described.

2. Description of the Related Art In recent years, devices that supply hot water using various types of energy are becoming popular in general households. Therefore, when these water heaters are involved in the generation or consumption of electric power, the accuracy of the calculation result can be improved by performing the calculation in step S5 of FIG. 2 taking such electric power into consideration.

In one embodiment, the information processing device 1 may acquire information regarding the user's water heater. In this case, the control unit 10 may display a screen as shown in FIG. 20 on the display unit 30 to prompt the user to input information regarding the water heater. The user can input information to the input unit 20 while viewing the display unit 30 on which a screen as shown in FIG. 20 is displayed. The control unit 10 stores information input to the input unit 20 in the storage unit 50 .

FIG. 20 shows a screen on which an installed water heater can be selected in order to specify the installation status of the user's water heater. In one embodiment, the control unit 10 may display a radio button object on the display unit 30 to prompt the user to input a selection, as shown in FIG. In this case, the control unit 10 detects a user's selection input to the input unit 20 (for example, clicking with a mouse). This allows the user to easily select the installed water heater.

For example, as shown in FIG. 20, the control unit 10 may prompt the user to select an installed water heater. For example, as shown in FIG. 20, assume that the user selects and inputs, for example, one of three options in response to the instruction "Please select an installed water heater" displayed on the display unit 30. . In the example shown in FIG. 20, at least one of "gas water heater", "heat pump water heater", and "hybrid water heater" is displayed so as to be selectable as three options corresponding to the selection input by the user. . In this case, the control unit 10 stores information on the water heater selected and input by the user in the storage unit 50 as information on the installed water heater of the user.

Here, it is assumed that the storage unit 50 stores a database that associates installed water heaters with information about the electric power of the water heaters. Thereby, the control unit 10 can read the information on the electric power caused by the installed water heater. Then, based on this power information, the control unit 10 can consider the power output by the user's power generation device and/or the power consumed by the user's load equipment. In one embodiment, even if the above-described database is not stored in the storage unit 50, the control unit 10 receives at least part of the above-described database information from an external device or an external server via the communication unit 40. may

For example, some water heaters, such as gas water heaters, use natural gas or the like to generate electrical energy and thermal energy. In this case, since the water heater generates electrical energy, it can be regarded as a power generator that acquires information in step S1 of FIG. Therefore, when the gas water heater is selected, the control unit 10 may also consider the power generated by the water heater in step S1 of FIG. 2 as the power generated by the power generator.

Further, for example, some water heaters, such as heat pump water heaters, generate thermal energy based on air energy and electric energy. In this case, since the water heater consumes electrical energy, it can be regarded as a load device in the step of acquiring the state and tendency of power consumption in step S3 of FIG. Therefore, when the heat pump water heater is selected, the control unit 10 may also consider the power consumed by the water heater in step S3 of FIG. 2 as the power consumption.

Further, for example, some water heaters, such as hybrid water heaters, use gas and/or electric energy to generate heat energy. In this case, since the water heater consumes electrical energy, it can be regarded as a load device in the step of acquiring the state and tendency of power consumption in step S3 of FIG. Therefore, when the hybrid water heater is selected, the control unit 10 may also consider the power consumed by the water heater in step S3 of FIG. 2 as the power consumption.

The example shown in FIG. 20 assumes that the user selects and inputs one of the three types of water heaters. However, for a user who has installed a plurality of water heaters among the three types of water heaters, the control unit 10 may allow the user to select and input a plurality of water heaters. Furthermore, the control unit 10 may perform a display on the display unit 30 asking the user whether or not there is an installed water heater on the screen immediately before transitioning to FIG. 20, for example. In this case, when the user selects the water heater “yes”, the control unit 10 may display the screen shown in FIG. 20 on the display unit 30 . On the other hand, if the user selects "no" water heater, the control unit 10 may skip the screen shown in FIG.

Furthermore, in general, the output characteristics of solar cells gradually deteriorate with the passage of power generation time due to various causes such as deterioration over time. In general, storage batteries also gradually deteriorate in storage and discharge characteristics with the passage of time for storing and discharging electricity due to various causes such as deterioration over time. Therefore, the accuracy of the calculation result can be improved by performing the calculation in step S5 of FIG. 2 taking into consideration the deterioration of at least one of the solar battery and the storage battery.

For example, assume that a solar cell installed (or considering installation) by a user exhibits a characteristic change over time as shown in FIG. 21A. FIG. 21A shows that the output capacity of the solar cell in 2018 is 100%, and the output capacity has decreased to 95.5% in 2027, the tenth year. Similarly, FIG. 21A shows that the output capacity of the solar cell in 2028 is 95.0%, and the output capacity has decreased to 90.5% in 2037, the twentieth year.

Also, for example, it is assumed that a storage battery installed (or considering installation) by the user exhibits a characteristic change over time as shown in FIG. 21B. FIG. 21B shows a state in which the power storage capacity of the storage battery in 2018 is 100%, and the power storage capacity is reduced to 55.0% in 2027, the tenth year. Therefore, in FIG. 21B, the storage battery is replaced in 2028, the output capacity of the storage battery in 2028 is 100%, and the storage capacity decreases to 55.0% again in 2037, the 20th year. showing. It should be noted that the case where the power storage device will not be installed after 2028 may also be indicated.

In this manner, the calculation performed in step S5 of FIG. 2 taking into account the deterioration of at least one of the solar battery and the storage battery can improve the accuracy of the calculation result performed by the control unit 10 .

In addition, in the above-described embodiments, the description has been given assuming that the storage battery as the user's power storage device is typically a stationary storage battery. However, in one embodiment, the user's power storage device is not limited to a stationary storage battery. For example, in one embodiment, the user's power storage device may be an electric vehicle with a built-in storage battery. In recent years, electric vehicles can charge power from solar cells or power from a grid, such as VtoH (Vehicle to Home). Electric power discharged from such an electric vehicle can also be used.

As described above, the information processing device 1 according to one embodiment outputs information regarding the combination of the power generation device and the power storage device that supply power to the load equipment. Here, the information processing apparatus 1 according to one embodiment outputs information about a combination of a power generation device and a power storage device capable of achieving a self-sufficiency period in response to input of information about the self-sufficiency period of electric power supplied to the load equipment. .

Here, the power storage device is charged with electric power output by a power generation device that performs solar power generation or the like. Also, if a power generator such as a fuel cell is included, the power output by the power generator may be charged. In the above-described embodiment, it has been described that the power charged in the power storage device among the power supplied from the grid power is not used for the calculation of the self-sufficiency period. Further, as described above, the “self-sufficiency period” can be specifically defined as “the number of self-sufficiency days (the length of “one day” is variable)”. Further, in the above-described embodiment, the input of information on the self-sufficiency period is described as "input" by the user. However, the control unit 10 may perform the calculation based on data received by the communication unit 40, for example. Further, when outputting information about the combination of the power generation device and the power storage device that can achieve the self-sufficiency period, it may be displayed on the display unit 30, for example, or the information may be sent to another device via the communication unit 40. You may send.

Further, the information processing apparatus 1 according to one embodiment, based on information on the power generated by the power generation device, information on the power charged and/or discharged by the power storage device, and information on the power consumption of the load device, You may output the information regarding the combination which can achieve a self-sufficiency period. In this way, the information processing apparatus 1 can provide highly accurate information to the user by outputting information calculated based on at least part of the information input by the user.

In addition, the information processing apparatus 1 according to one embodiment may output information about a combination that can achieve the ratio of the self-sufficiency period to the predetermined period in response to the input of the information about the ratio of the self-sufficiency period to the predetermined period. In the above-described embodiment, the case where the self-sufficiency period is "self-sufficiency days" has been mainly described. However, the self-sufficiency period may be defined as a ratio of the self-sufficiency period to a predetermined period, such as a "self-sufficiency rate". Further, when outputting information about the combination of the power generation device and the power storage device that can achieve the self-sufficiency period, the control unit 10 outputs not only the self-sufficiency period but also information about the prices of the power generation device and the power storage device, for example. good.

In addition, the information processing apparatus 1 according to one embodiment provides information on a combination that can achieve the self-sufficiency period, and selects a combination corresponding to the self-sufficiency period that is closest to the self-sufficiency period input by the user, out of the combinations that can achieve the self-sufficiency period. It may be output together with suggestive information. For example, as described above, the control unit 10 encloses a combination that achieves the self-sufficiency period closest to the self-sufficiency period input by the user among a plurality of combinations that can achieve the self-sufficiency period, or adds a color to the combination. For example, it may be displayed so that it can be easily distinguished from other information. Thereby, the user can easily grasp the combination closest to the user's request at a glance among the plurality of combinations that can achieve the self-sufficiency period.

In addition, the information processing apparatus 1 according to one embodiment outputs information about a combination that can achieve the self-sufficiency period, together with information suggesting a combination corresponding to the self-sufficiency period in which the self-sufficiency period input by the user has a predetermined width. You may For example, as described above, the control unit 10 encloses combinations in which a self-sufficiency period with a predetermined width in the self-sufficiency period input by the user is achieved with a bold frame or colors, and other combinations are displayed. It may be displayed so that it can be easily distinguished from information. As a result, the user can easily grasp not only the combination closest to the user's desire, but also combinations before and after that combination at a glance.

Further, the information processing apparatus 1 according to one embodiment may output information about a combination that can achieve the self-sufficiency period together with information compared with other combinations other than the combination. For example, as described above, the control unit 10 may also output a combination other than the combination capable of achieving the self-sufficiency period, as shown in FIG. 16, for example. As a result, the information processing device 1 can provide the user with effective information for making a decision when the display unit 30 displays information about the combination of the power generation device and the power storage device that can achieve the self-sufficiency period.

Further, the information processing apparatus 1 according to one embodiment may output information about a combination capable of achieving the self-sufficiency period together with information on the number or installed capacity of at least one of the power generation device and the power storage device. As a result, when the display unit 30 displays the information about the combination of the power generation device and the power storage device that can achieve the self-sufficiency period, the user can see at a glance how many power generation devices and/or power storage devices should be installed. can be easily grasped.

In addition, the information processing device 1 according to one embodiment may output information about a combination capable of achieving the self-sufficiency period together with information about the combination of the power generation device and the power storage device. As a result, when the information on the combination of the power generation device and the power storage device that can achieve the self-sufficiency period is displayed on the display unit 30, the user can easily grasp the mode of the combination of the power generation device and/or the power storage device at a glance. can do.
