When the operation of the information processing apparatus 1 according to the embodiment starts, first, the information input by the user is acquired (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 apparatus 1 outputs information regarding 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 way on, for example, the display unit 30. Hereinafter, the processing performed in each step will be further described.

In one embodiment, the process of acquiring information in steps S1 to S4 may be performed in any order as long as it is performed before the process of calculating in step S5. Therefore, the control unit 10 of the information processing apparatus 1 can perform the processes in steps S1 to S4 in any order.

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

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

In photovoltaic power generation, the generated power depends on the location of the solar cell to be installed (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 photovoltaic power generation device. The user can input information to the input unit 20 while visually recognizing the display unit 30 on which the screen as shown in FIG. 3 is displayed. The control unit 10 stores the information input to the input unit 20 in the storage unit 50.

FIG. 3 shows a screen in which a prefecture and / or district can be selected in order to specify the installation location of the user's photovoltaic power generation device. Further, as shown in FIG. 3, the installation location of the user's photovoltaic power generation device may be specified, for example, by searching from an address or a zip 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, as shown in FIG. 3, for example, the map including the position is displayed so as to be gradually enlarged based on the input of the user who specifies the position on the Japanese map (for example, click with the mouse). The installation location of the photovoltaic power generation device may be specified. In addition, for example, the amount of power generated by the photovoltaic power generation device is calculated, such as whether there is an element that shades the installation location of the photovoltaic power generation device during the daytime (for example, it is in the shadow of the mountain after 15:00). If there is information that is useful to you, you may be able to enter such information.

Here, it is assumed that the storage unit 50 stores a database corresponding to the location of the solar cell to be installed and the amount of solar radiation expected at the location where the solar cell is installed. As a result, the control unit 10 can read out the expected amount of solar radiation at the location of the installed solar cell. Then, the control unit 10 can calculate the amount of electric power generated by the user's photovoltaic power generation device based on the amount of solar radiation. In one embodiment, even if the above-mentioned database is not stored in the storage unit 50, the control unit 10 receives at least a part of the information of the above-mentioned database from an external device, an external server, or the like via the communication unit 40. You may. In this case, in an external device or an external server, the correction value of the amount of solar radiation due to the topography around the place is calculated based on the contour map around the place where the solar cell is installed, and the control unit 10 is the communication unit 40. It may be reflected in the information received via.

Before displaying the screen shown in FIG. 3, the control unit 10 may display, for example, the question "Are there already installed solar cells?" And the option of "Yes / No" on the display unit 30. .. When "Yes" is selected and input in response to such a question, the control unit 10 may display the display unit 30 on an input screen for various information related to 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 the 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 photovoltaic power generation device. When the input on the screen shown in FIG. 3 is completed, the control unit 10 displays the next screen in response to the user's input to the object of the "Next" button at the lower right.

The information input by the user in FIG. 3 may be information on the place 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 a place where the user is currently considering installing a photovoltaic power generation device (for example, a place where the user is considering purchasing such as a home).

As shown in FIG. 3, on each screen, the object of the "Next" button can be displayed in the lower right, and the object of the "Previous" button can be displayed in the lower left. On each screen, when the user's input (for example, clicking with a mouse) to the "Next" button is detected, the control unit 10 may transition to the display of the screen to be displayed next. Similarly, when the user's input (for example, clicking with a mouse) to the "forward" button is detected, the control unit 10 may shift to the display of the screen displayed immediately before.

Further, in photovoltaic power generation, the amount of power generated depends on the configuration of the installed solar cell (what kind of solar cell is installed). Therefore, in one embodiment, the information processing device 1 acquires information on the configuration 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 photovoltaic power generation device. The user can input information to the input unit 20 while visually recognizing the display unit 30 on which the screen as shown in FIG. 4 is displayed. The control unit 10 stores the information input to the input unit 20 in the storage unit 50.

FIG. 4 shows a screen in 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 state in which a gable-shaped roof of a house is viewed from diagonally above. In the display example of the screen shown in FIG. 4, the number of solar cell modules configured is the same, but the number of solar cell elements constituting the module alone and the power generation efficiency are different, so that the total power generation amount in each example is different. .. In one embodiment, as shown in FIG. 4, the control unit 10 may display the object of the radio button on the display unit 30 in order to prompt the user to select and input. In this case, the control unit 10 detects a user's selection input (for example, clicking with a mouse) to the input unit 20. This allows the user to easily select the installation scale and output of the installed photovoltaic power generation device. Further, when the configuration of the user's photovoltaic power generation device is not an option, the control unit 10 may prompt the input of the installation scale (size) and / or the output details of the user's photovoltaic power generation device.

Here, it is assumed that the storage unit 50 stores a database corresponding to the scale (size) of the installed solar cell and the corresponding output. As a result, the control unit 10 can read the output corresponding to the scale (size) from the scale (size) of the installed solar cell. In one embodiment, even if the above-mentioned database is not stored in the storage unit 50, the control unit 10 receives at least a part of the information of the above-mentioned database from an external device, an external server, or the like via the communication unit 40. You may. Further, in an external device, an external server, or the like, information having a scale closest to the scale of the solar cell based on the input of the user may be selected, 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 apparatus 1 can obtain information on the configuration (installation scale and output) of the user's photovoltaic power generation apparatus. When the input on the screen shown in FIG. 4 is completed, the control unit 10 displays the next screen in response to the user's input to the object of the "Next" button at 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) in which the user is currently considering the installation of the photovoltaic power generation device.

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

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

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

Here, it is assumed that the storage unit 50 stores a database corresponding to the installation angle and orientation of the solar cell and the expected amount of solar radiation. As a result, 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 electric power generated by the user's photovoltaic power generation device based on the amount of solar radiation. In one embodiment, even if the above-mentioned database is not stored in the storage unit 50, the control unit 10 receives at least a part of the information of the above-mentioned database from an external device, an external server, or the like via the communication unit 40. You 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 direction 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 in response to the user's input to the object of the "Next" button at the lower right.

The information input by the user in FIG. 5 may be information on the installation angle and installation direction 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 the installation direction in which the user is currently considering the installation of the photovoltaic power generation device.

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

As shown in FIG. 2, when the above information is acquired in step S1, the control unit 10 then acquires information regarding the power storage device (step S2).

Based on the information acquired in step S2, the control unit 10 calculates the amount of electric 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 visually recognizing the display unit 30 on which the screen as shown in FIG. 6 is displayed. The control unit 10 stores the 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 storage battery of the user. In one embodiment, as shown in FIG. 6, the control unit 10 may display a radio button object on the display unit 30 in order to prompt the user for selection input. In this case, the control unit 10 detects a user's selection input (for example, clicking with a mouse) to the input unit 20. As a result, the user can easily select the presence or absence of the installed storage battery.

For example, as shown in FIG. 6, it is assumed that the user selects and inputs "No" in response to the question "Are there already installed storage batteries?" Displayed on the display unit 30. In this case, the control unit 10 stores the fact that there is no storage battery of the user already installed (that is, the capacity that can be stored is zero) in the storage unit 50. Further, when the user's storage battery is already installed, the control unit 10 may prompt the input of the details of the installed user's storage battery as shown in FIG. For example, as shown in FIG. 6, it is assumed that the user selects and inputs "Yes" to the question "Are there already installed storage batteries?" Displayed on the display unit 30. In this case, the control unit 10 may display a screen prompting the user to select or input the storage capacity of the storage battery of the already installed user on the display unit 30. Then, the control unit 10 stores the storage capacity of the user's storage battery already 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 the model name of the storage battery.

Here, it is assumed that the storage unit 50 stores a database corresponding to the installed storage battery and the expected storage amount. Here, the expected storage amount may be the amount of power expected to be charged by surplus power among the amount of power generated by the solar cell. Further, the expected storage capacity may be a practical storage capacity in charge / discharge in consideration of extending the life of the storage battery. Further, the expected amount of electricity stored may be simply the amount of electric power output to cover the electric power supplied to the load. From the above-mentioned database, the control unit 10 can read out the expected storage amount of the storage battery from the installed storage battery. Then, the control unit 10 can calculate the amount of electric power output by the user's storage battery based on the amount of stored electricity. In one embodiment, even if the above-mentioned database is not stored in the storage unit 50, the control unit 10 receives at least a part of the information of the above-mentioned database from an external device, an external server, or the like via the communication unit 40. You may.

When the input on the screen shown in FIG. 6 is completed, the information processing device 1 can obtain the information of 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 in response to the user's input to the object of the "Next" button at 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 currently being considered for installation by the user.

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

As shown in FIG. 2, when the above information is acquired in step S2, the control unit 10 then acquires information regarding the status and tendency of power consumption (step S3).

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

In one embodiment, the information processing apparatus 1 first acquires information on the power consumption of the load device of the user as the power consumption status. 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 visually recognizing the display unit 30 on which the screen as shown in FIG. 7 is displayed. The control unit 10 stores the information input to the input unit 20 in the storage unit 50.

FIG. 7 is a screen in which the situation of a house such as the user's home, the family structure of the user, and the power consumption of the user's load device can be collectively selected in order to specify the power consumption of the user's load device. 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 in order to prompt the user for selection input. In this case, the control unit 10 detects a user's selection input (for example, clicking with a mouse) to the input unit 20. As a result, the user can easily select the condition of the building of the house such as the user's home, the family structure of the user, and the power consumption of the load device of the user at once.

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

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

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

In FIG. 8, "daytime type", "nighttime type", and "intermediate type" are selectively displayed as the user's life pattern from the viewpoint of lightening the operation burden of the user. Therefore, the user only has to select the option that most closely matches his or her situation. In FIG. 8, as reference information, a model of the power consumption ratio for each time zone is displayed for each life pattern. Here, the "daytime type" may be a life pattern that consumes electric power even in the daytime, for example, a house in which a full-time housewife and / or an elderly person and / or a small child lives. Further, the "night type" may be a lifestyle pattern in which power consumption is low during the daytime and power consumption is consumed during the nighttime, such as a single-person household or a house in which a double-income couple and a student's family live. Further, the "intermediate type" does not correspond to the typical "day type" or "night type", and may be an intermediate life pattern between them.

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, for example, a screen prompting the user to input a specific ratio of power consumption for each time zone on the display unit 30.

Further, in one embodiment, the information processing apparatus 1 acquires information on the user's electricity charge as a power consumption situation and / or a tendency. 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 charge. The user can input information to the input unit 20 while visually recognizing the display unit 30 on which the screen as shown in FIG. 9 is displayed. The control unit 10 stores the information input to the input unit 20 in the storage unit 50.

FIG. 9 shows a screen on which the user's electricity charge can be input in order to identify the power consumption status and / or tendency of the user's load device. FIG. 9 shows a screen on which a contracted electric power company, an electric power plan, and the like can be selected in order to specify a user's electric power charge. Further, in one embodiment, as shown in FIG. 9, the control unit 10 may display the object of the radio button on the display unit 30 in order to prompt the user to select and input. In this case, the control unit 10 detects a user's selection input (for example, clicking with a mouse) to the input unit 20. As a result, the user can easily select the input mode of the electricity charge.

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

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

The information input by the user in FIGS. 7 to 9 may be information based on the load device 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 device currently being considered for installation by the user.

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

As shown in FIG. 2, when the above information is acquired in step S3, the control unit 10 then acquires information regarding 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 apparatus 1 acquires information regarding a self-sufficiency period desired by the user. In this case, the control unit 10 may display a screen as shown in FIGS. 10A and 10B on the display unit 30 to prompt the user to input information regarding the desired self-sufficiency period. The user can input information to the input unit 20 while visually recognizing the display unit 30 on which the screen as shown in FIGS. 10A and 10B is displayed. The control unit 10 stores the information input to the input unit 20 in the storage unit 50.

In one embodiment, the self-sufficiency period can be a self-sufficient period of electric power. That is, the self-sufficiency period can be a period in which the power consumption can be covered by the 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 embodied as, for example, "self-sufficiency days" or "self-sufficiency rate". Here, the number of self-sufficiency days is a representation of the self-sufficiency period in terms of the number of days. For example, when the self-sufficiency period is "3 days", it means that the power consumption can be covered by the power output from the user's power generation device and / or power storage device without purchasing power from the grid for 3 days. means. Further, the self-sufficiency period "3 days" does not necessarily have to be a continuous time. For example, it may be a self-sufficiency period of "total 3 days" due to the existence of three self-sufficient "1 days" in a predetermined period (typically 365 days). The self-sufficiency rate is a ratio of the self-sufficiency period to a predetermined period (for example, 365 days). For example, when the self-sufficiency rate is "2%" when the predetermined period is 365 days, it is output from the user's power generation device and / or power storage device without purchasing power from the grid for 7.3 days. It means that electricity can cover the power consumption. In this case as well, "7.3 days" does not necessarily have to be a continuous time. For example, the self-sufficient "1 hour (for example, when the minimum unit is 1 hour)" is 176 times (calculated 175.2 times is the minimum unit) in a predetermined period (typically 365 days = 8760 hours). It may be a self-sufficiency period of "total 176 hours" due to existence.

FIG. 10A shows a screen in which it is possible to select whether to input the self-sufficiency period as the “self-sufficiency days” or the self-sufficiency period as the “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 in order to prompt the user for selection input, as shown in FIG. 10A. In this case, the control unit 10 detects a user's selection input (for example, clicking with a mouse) to the input unit 20. Thereby, the user can easily select the mode of inputting the self-sufficiency period.

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

Further, in one embodiment, as shown in FIG. 10A, a screen for setting the number of days as a reference for the self-sufficiency period may be displayed on the display unit 30. In the example shown in FIG. 10A, the standard for the self-sufficiency period is set to 365 days by default. In this case, the control unit 10 may change the number of days as a reference for the self-sufficiency period from 365 days according to the input of the user. 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 a screen on the display unit 30 in which the definition of one day of self-sufficiency can be set. In one embodiment, the control unit 10 may display a radio button object on the display unit 30 in order to prompt the user for selection input, as shown in FIG. 10B. In this case, the control unit 10 detects a user's selection input (for example, clicking with a mouse) to the input unit 20. This allows the user to easily select whether or not to define the self-sufficiency period of 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 by 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, it may be desired to consider the number of self-sufficient days only during the night time of living at home in a day. In addition, for example, in the case of a user who wants to consider a self-sufficiency period such as a building of a medical institution, there may be a case where he / she wants to consider the number of self-sufficiency days that can handle double power consumption in an emergency, with one day as a unit such as 48 hours. be. Therefore, in one embodiment, as shown in FIG. 10B, the control unit 10 may be able to set the number of self-sufficient days to be other than 24 hours as a definition. Further, in one embodiment, as shown in FIG. 10B, the control unit 10 may be able to set a time zone in which one day of self-sufficiency days is other than 24 hours. As described above, according to the information processing device 1 according to the embodiment, the introduction or change of the power generation device and / or the power storage device is considered based on the self-sufficiency period or the number of days suitable for the practical purpose of each user. Can be done. Further, even when the input of the "self-sufficiency rate" desired by the user is selected on the screen shown in FIG. 10A, as shown in FIG. 10B, there is also a time zone when one day in the calculation of the self-sufficiency rate is other than 24 hours. 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 the information of 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 in response to the user's input to the object of the "Next" button at the lower right.

As shown in FIG. 2, when the above information is acquired in step S4, the control unit 10 then 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 acquired 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 generation power of the power generation device and the storage capacity of the power storage device are the respective elements.

Next, a process of 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 the embodiment will be described. First, a case where the self-sufficiency period is calculated as the number of self-sufficiency days will be described.

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

When the process shown in FIG. 11 starts, the control unit 10 acquires the definition of one day of self-sufficiency days (step S11). In step S11, the control unit 10 may read the information of the self-sufficiency period acquired in step S4 shown in FIG. 2 from the storage unit 50. The definition of one day of self-sufficiency days acquired in step S11 may be a definition of the time constituting one day of self-sufficiency days desired by the user. Further, when the definition of the number of self-sufficient days acquired in step S11 is not 24 hours, the definition of the time zone of the time constituting the day may be used.

When the definition of one day is acquired in step S11, the control unit 10 acquires the power consumption (kWh) (1) of the load device of the user (step S12). In step S12, the control unit 10 may read out the power consumption status and trend information acquired in step S3 shown in FIG. 2 from the storage unit 50. Then, the control unit 10 acquires the power consumption of the load device of the user in a time unit 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 generation device (step S13). In step S13, the control unit 10 may read the information on the power consumption of the load device of the user acquired in step S12 and the information on the power generation device acquired in step S1 shown in FIG. 2 from the storage unit 50. Then, based on the acquired information, the control unit 10 is covered by a power generation device such as a solar cell among the power consumption of the load device of the user in a time unit such as a predetermined 30 minutes on the time axis. Calculate the amount of power generated.

After the power consumption amount covered by the power generation device is calculated in step S13, the control unit 10 calculates the power consumption amount (kWh) (3) of the load covered by the power storage device (step S14). In step S14, the control unit 10 may read the information on the power consumption of the load device of the user acquired in step S12 and the information on the power storage device acquired in step S2 shown in FIG. 2 from the storage unit 50. Then, based on the acquired information, the control unit 10 is covered by a power storage device such as a storage battery among the power consumption of the load device of the user 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 the power can be self-sufficient in the day defined in step S11 (step S15). In step S15, the control unit 10 determines the power consumption (2) of the load covered by the above-mentioned power generation device, which is acquired in a time unit such as a predetermined 30 minutes on the time axis, for one day defined in step S11. Add only time. Similarly, in step S15, the power consumption amount (3) of the load covered by the above-mentioned power storage device acquired by the control unit 10 in a time unit such as a predetermined 30 minutes on the time axis is also defined in step S11. Add only the time of the day. Similarly, in step S15, the power consumption (1) of the load device of the above-mentioned user acquired by the control unit 10 in a time unit such as a predetermined 30 minutes on the time axis is also defined in step S11 for one day. Only the time of is added. Then, in step S15, if the sum of the power consumption amount (2) and the power consumption amount (3) reaches the value of the power consumption amount (1), the control unit 10 is self-sufficient in power consumption in one day. Is determined to be 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 daily power consumption of the load device is correct. When the value of is reached, it can be determined that "self-sufficiency" is possible.

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

After adding the number of self-sufficiency days in step S16, the control unit 10 determines whether or not the calculation from step S12 to step 16 has been performed for the number of self-sufficiency days in a predetermined period (step S17). In step S17, the control unit 10 may determine whether or not the calculation from step S12 to step 16 has 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 the self-sufficiency of electric power in one day is not possible, the control unit 10 skips the process of step S16 and performs the process of step S17 without adding the number of self-sufficiency days for one day.

If the number of self-sufficient days in a predetermined period has 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 is performed for the number of self-sufficient days in a predetermined period in step S17, the control unit 10 outputs the information on the number of self-sufficient days to, for example, a storage unit 50 (step S18), and performs the process shown in FIG. finish. When the processing up to step S18 is performed, the control unit 10 can output information on the number of self-sufficiency days 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, the self-sufficiency period (number of self-sufficiency days) achieved by each combination can be calculated by performing the processing shown in FIG. 11 for each combination.

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 combinations assumed for each of the power generation option of the power generation device and the storage capacity option of the power storage device. For example, it is assumed that 12 options are assumed for the generated power of the power generation device and 3 options are assumed for the 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 FIG. 12 for each combination of the power generation device and the power storage device as described above 36. ..

Further, for example, the combination of the power generation device and the power storage device is a combination limited based on the user's input among all the combinations assumed for each of the power generation option of the power generation device and the storage capacity option of the power storage device. May be good. For example, the power generation capacity of the power generation device that the user has already installed or is considering to be installed is limited to 4 options, and the storage capacity of the power storage device that the user has already installed or is considering to install is 2. It is assumed that the options are limited to. In this case, there are a total of eight combinations of the power generation device and the power storage device. In this case, the control unit 10 may perform the process of FIG. 11 or 12 for each combination of the eight power generation devices and the power storage devices, and calculate the self-sufficiency period (self-sufficiency days or self-sufficiency rate) that can be achieved by each combination. ..

In the example described in FIG. 11, the number of self-sufficient days was calculated in units of 30 minutes on the time axis. However, the length of time used to calculate the number of self-sufficiency days is arbitrary. For example, if there is a margin in the processing capacity of the control unit 10 and / or the storage capacity of the storage unit 50, a more accurate number of self-sufficiency days may be calculated 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 number of self-sufficiency days may be calculated in units of one hour on the time axis.

Next, a case where the self-sufficiency period is calculated as the self-sufficiency rate will be described.

FIG. 12 is a flowchart showing a 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. 11. Hereinafter, 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 performed by the control unit 10 will be described.

Since the processes from step S11 to step S14 shown in FIG. 12 are the same as those described in FIG. 11, a more detailed description will be omitted.

After the processing up to step S14 is performed, the control unit 10 then performs the processing of step S25 shown in FIG. 12 as follows. In step S25, the control unit 10 is the sum of the power consumption of the load covered by the power generation device (2) and the power consumption of the load covered by the power storage device (3) (that is, (2) +). (3)) is added at predetermined time intervals. Further, in step S25, the control unit 10 also adds the power consumption amount (1) of the load device of the user described above at predetermined time intervals. Here, the predetermined time for adding the above (2) + (3) and the above (1), respectively, is the same as the above-mentioned predetermined time, for example, the above (1) to (3) are acquired respectively. It may be a time unit such as a predetermined 30 minutes on the time axis.

When the addition is performed in step S25, the control unit 10 determines whether or not the addition is performed for the time of the 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 "1 day". If it is determined in step S26 that the addition for one day has not been performed, the control unit 10 returns to step S12 and repeats the process.

On the other hand, when it is determined in step S26 that the addition for one day 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 a 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, for example, steps S25 to S27. Specifically, the self-sufficiency rate is the value obtained by dividing the value of ((2) + (3)) added for a predetermined period in step S27 by the value of (1) added for a predetermined period in step S27. , 100 may be used as the value obtained by multiplying.

When the self-sufficiency rate is calculated in step S28, the control unit 10 outputs the self-sufficiency rate information to, for example, a storage unit 50 (step S29), and ends the process shown in FIG. When the processing up to step S29 is performed, the control unit 10 can output information on 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, it is the same as described in FIG. 11 that 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. 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 the self-sufficiency rate 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 regarding the combination capable of achieving the self-sufficiency period input by the user (step). S6).

FIG. 13 is a flowchart illustrating a process of outputting information regarding a combination capable of achieving the self-sufficiency period input by the user, which is performed in step S6 shown in FIG. 2, in more detail. Hereinafter, an example in which the self-sufficiency period is set as the number of self-sufficiency days will be described, but when the self-sufficiency period is set as the self-sufficiency rate, it can be similarly performed by replacing "days" with "rate" in the following explanation.

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 has a number of self-sufficiency days (calculated in step S5) achieved by one of the combinations of the power generation device and the power storage device, which is equal to or greater than the number of self-sufficiency days (acquired in step S4) input by the user. Judge whether or not. The combination of the power generation device and the power storage device determined in step S31 may be one combination selected from the combination of the power generation device and the power storage device for which the number of self-sufficiency days was calculated in step S5. In one embodiment, one combination determined in step S31 may be selected in a predetermined order among the (plural) combinations of the power generation device and the power storage device for which the number of self-sufficiency days is calculated in step S5.

When the number of self-sufficiency days achieved by one combination in step S31 is equal to or greater than the number of self-sufficiency days input by the user, the control unit 10 performs the process of step S32. In step S32, the control unit 10 outputs information regarding the one combination in a mode indicating that the number of self-sufficiency days input by the user can be achieved (hereinafter, appropriately referred to as "a mode indicating achievability"). (Step S32). In step S32, the aspect showing achievability can be various aspects. For example, the aspect indicating achievability may be an aspect in which information about the one combination is displayed together with a character indicating that the number of self-sufficiency days input by the user is achievable. Further, the aspect indicating achievability may be an aspect in which the information regarding the one combination is displayed so as to be distinguished from the others by being color-coded or surrounded by a frame. Typically, the achievable aspect may be an aspect that is presented distinguishably from information about combinations that cannot achieve the self-sufficiency days entered by the user.

After the processing of step S32 is performed, the control unit 10 performs the processing of step S33. On the other hand, if the number of self-sufficiency days achieved by one combination in step S31 is not equal to or greater than the number of self-sufficiency days input by the user, the control unit 10 skips the process of step S32 and performs the process 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 the combinations of the power generation device and the power storage device for which the number of self-sufficiency days was calculated in step S5. If the determination process has not yet been performed for all the combinations in step S33, the control unit 10 returns to step S31 and continues the process. When returning to step S31, the control unit 10 performs a determination process of whether or not the number of self-sufficiency days is equal to or greater than the number of self-sufficiency days input by the user for one of the combinations for which the determination process of step S31 has not yet been performed. good.

On the other hand, when the determination process has been performed for all the combinations in step S33, the control unit 10 ends the process shown in FIG. By such processing, the control unit 10 can output information regarding a combination capable of achieving the self-sufficiency period input by the user.

In step S6 shown in FIG. 2, the control unit 10 displays various information including information on the combination of the power generation device and the power storage device capable of achieving the self-sufficiency period input by the user based on the calculation in step S5. It may be displayed at 30. 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. Only may be presented.

Further, for example, in the operation shown in FIG. 2, the achievable self-sufficiency period changes by changing at least one of the information of the power generation device acquired in step S1 and the information of the power storage device acquired in step S2. 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 in which the self-sufficiency period has a predetermined width, including the self-sufficiency period desired by the user. You can leave it. For example, in general, adding at least one of a power generation device and a power storage device also increases the self-sufficiency period. In general, reducing the number of installations of at least one of the power generation device and the power storage device also reduces the self-sufficiency period. As described above, the information including the combination of the power generation device and the power storage device that achieves the self-sufficiency for the period in which the self-sufficiency period desired by the user has a predetermined range can be useful information for the user. Therefore, in step S6, the control unit 10 may output information including information on the combination of the power generation device and the power storage device that achieves self-sufficiency for a period in which the self-sufficiency period desired by the user has a predetermined width.

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 in which the information output in step S6 of FIG. 2 is displayed on the display unit 30.

FIG. 14 is a diagram showing an example of the number of self-sufficiency days achieved when the installed capacity (power generation) of the solar cell is variable while the number of storage batteries (storage capacity) of the user is fixed. In the example shown in FIG. 14, for example, the user skips the input of the solar cell information shown in FIGS. 4 and 5, and inputs only one storage battery information (storage capacity 6.5kWh) shown in FIG. , The input of the number of self-sufficiency days shown in FIG. 10A may also be displayed when the input is skipped. That is, the example shown in FIG. 14 shows how many self-sufficient days can be achieved when the user installs only one storage battery and installs or expands a solar cell. For example, as shown in FIG. 14, the number of self-sufficient days is zero even if a 1 kW solar cell is installed with the user's storage battery installed, but the number of self-sufficient days is 18 days if a 2 kW solar cell is installed. .. Further, as shown in FIG. 14, if a 10 kW solar cell is installed with the user's storage battery installed, the number of self-sufficient 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 (how many hours from what time to what time). Further, in calculating the number of self-sufficiency days, the reference period may be one year such as 365 days, or may be any period other than 365 days. Further, for example, in calculating the number of self-sufficiency days, the reference period may be a specific period such as summer or winter. Further, in FIG. 14, the value of each output 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 in which the information output in step S6 of FIG. 2 is displayed on the display unit 30.

FIG. 15 is a diagram showing an example of the number of self-sufficiency days achieved when the storage capacity (for example, the number) of the user's storage battery is variable to three values and the installed capacity (power generation) of the solar cell is also variable from 5 kW. Is. Here, the installed capacity of the solar cell (generated power) may be, for example, the generated capacity of the solar cell (for example, the number of solar cell modules). In the example shown in FIG. 15, for example, the user selectively inputs 5 kW of information for the solar cell shown in FIG. 4, and selects and inputs “No” for the installation of the storage battery shown in FIG. 6, and is shown in FIG. 10A. It may be displayed when the input of the number of self-sufficiency days is also skipped. That is, in the example shown in FIG. 15, when a user installs (or considers) a storage battery having three types of capacities and installs a 5 kW solar cell, how many self-sufficient days can be achieved is collectively shown. There is.

For example, as shown in FIG. 15, the number of self-sufficient days is zero even if a 5 kW solar cell is installed with a 3.2 kWh storage battery installed, but if the number of solar cells is increased to 13 kW, the number of self-sufficient days is one day. It becomes. For example, as shown in FIG. 15, if a 6.5 kW storage battery is installed and a 5 kW solar cell is installed, the self-sufficiency day is 97 days, but if the solar cell is increased to 6 kW, the self-sufficiency day is 115 days. It becomes. Further, for example, as shown in FIG. 15, if a 12kWh storage battery is installed, the number of self-sufficient days when a 5kW solar cell is installed is 250 days, and if a solar cell is added, the number of self-sufficiency days is further increased.

Even in the number of self-sufficient days shown in FIG. 15, the user can freely set the definition and the reference period of one day. Further, as shown in FIG. 15, the control unit 10 may be color-coded and displayed on the display unit 30 depending on whether the solar cell is not added or the solar cell is added. For example, suppose that a user is currently installing a 5 kW solar cell 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 the case where the solar cell is used as it is and the case where the solar cell is added or changed based on the information shown in FIG. ..

When introducing or expanding solar cells, it is assumed that there is an upper limit to the number of solar cell modules that can be installed on the roof of a house, for example. Therefore, if the upper limit of the solar cell module or the like that can be installed can be grasped in advance, the control unit 10 may not display the combination that exceeds the upper limit on the display unit 30. For example, there is a limit to the solar cell modules and the like that can be installed on the roof of a house, and it is assumed that the power generation of 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 the combination such that the generated power of the solar cell exceeds 10 kW. In FIG. 15, as a result of not outputting the information regarding the combination in which the generated power of the solar cell exceeds 10 kW, the information regarding the combination in which the generated power of the solar cell exceeds 10 kW is shown in the blank.

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

FIG. 16 is a diagram showing another example in which the information output in step S6 of FIG. 2 is displayed on the display unit 30.

FIG. 16 is a diagram showing an example of the number of self-sufficiency days achieved when the stored capacity (for example, the number) of the storage battery of the user is variable in three values and the installed capacity (power generation amount) of the solar cell is also variable. In the example shown in FIG. 16, for example, the user skips the input of the solar cell information shown in FIGS. 4 and 5, and the installation of the storage battery shown in FIG. 6 is selected and input as “No”, and is shown in FIG. 10A. It may be displayed when the number of self-sufficiency days is entered as 250 days. That is, the example shown in FIG. 16 shows that a user installs (or considers) three types of capacity storage batteries, and what kind of solar cells can achieve 250 days of self-sufficiency. ing.

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

Even in the number of self-sufficient days shown in FIG. 16, the user can freely set the definition and the reference period of one day. Further, as shown in FIG. 16, the control unit 10 displays information on the combination of the solar cell and the storage battery that has achieved the self-sufficiency period desired by the user, for example, by color-coding or enclosing the information in a frame. It may be displayed on the display unit 30 so as to be distinguishable. For example, in FIG. 16, the information portion of the combination in which the self-sufficiency period has achieved 250 days is shown by enclosing it in a thick frame in response to the input that the self-sufficiency period desired by the user is 250 days. As a result, the user can easily understand that a 5 kW solar cell and a 12 kWh storage battery should be installed in order to achieve the self-sufficiency period of 250 days. In addition, the user can easily grasp how much output a solar cell should be installed together with a 12kWh storage battery in order to achieve a self-sufficiency period of more than 250 days.

FIG. 17 is a diagram showing another example in which the information output in step S6 of FIG. 2 is displayed on the display unit 30.

FIG. 17 is achieved when the storage capacity (for example, the number) of the storage battery of the user is variable of three values and the installed capacity (power generation amount) of the solar cell is also variable, as in the example shown in FIG. It is a figure which shows the example of the self-sufficiency days. In the example shown in FIG. 17, the self-sufficiency period under a different situation from the example shown in FIG. 16 is shown. Therefore, in the example shown in FIG. 17, the self-sufficiency period that can be achieved by the combination of each solar cell and storage battery may be different from the example shown in FIG.

In the example shown in FIG. 17, for example, the user skips the input of the solar cell information shown in FIGS. 4 and 5, and the installation of the storage battery shown in FIG. 6 is selected and input as “No”, and is shown in FIG. 10A. It may be displayed when the number of self-sufficiency days is entered as 300 days. That is, the example shown in FIG. 17 shows that the user installs (or considers) three types of capacity storage batteries, and what kind of solar cells can be installed to achieve 300 days of self-sufficiency. ing.

For example, as shown in FIG. 17, when a 12kWh storage battery is installed, the number of self-sufficient days does not reach 300 days even if the solar cell is installed up to 4kW, but 300 days when the solar cell is installed at 5kW or more. It turns out that can be achieved.

Further, as shown in FIG. 17, the control unit 10 distinguishes the price range of the cost required for the combination of the solar cell and the storage battery that achieves each self-sufficiency day from the others by, for example, color-coding or enclosing it in a frame. It may be displayed on the display unit 30 so that it can be displayed. For example, in FIG. 17, the price range of the cost required for the combination of the solar cell and the storage battery to achieve each self-sufficiency day is shown in different colors in units of 1 million yen. As a result, the user can get an outline of the cost required for the combination of the solar cell and the storage battery to achieve each self-sufficiency 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 device 1 according to the embodiment, the combination of the power generation device and the power storage device can be presented from the viewpoint of the self-sufficiency period such as the number of self-sufficiency days of electric power. Therefore, the user can obtain effective judgment material when making a decision on the introduction or change of the power generation device and / or the power storage device. Therefore, according to the information processing apparatus 1 according to the embodiment, convenience can be enhanced.

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

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

FIG. 18 is a diagram showing another example in which the information output in step S6 of FIG. 2 is displayed on the display unit 30.

In the same scene as the example shown in FIG. 17, the information regarding 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. It is a figure which shows an example.

The example shown in FIG. 18 may be displayed when the number of self-sufficiency days shown in FIG. 10A is input as 300 days, as in the example shown in FIG. That is, in the example shown in FIG. 18, similar to the example shown in FIG. 17, when the user installs (or considers) a storage battery having three types of capacities and further installs any solar cell, 300 It shows whether the number of self-sufficient days can be achieved.

Here, as shown in FIG. 18, the control unit 10 can further distinguish the information about the combination corresponding to the self-sufficiency period closest to the user's input by, for example, color-coding or enclosing it in a frame. It may be displayed on the display unit 30. For example, in FIG. 18, among the combinations that can achieve the self-sufficiency period of 300 days entered by the user, the information (display of 300 days) regarding the combination corresponding to the self-sufficiency period of 300 days closest to the user's input is conspicuously displayed. Has been done. From 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.

Further, for example, in FIG. 18, it is assumed that the self-sufficiency period entered by the user is 220 days. In this case, the control unit 10 makes conspicuous information (display of 228 days) regarding the combination corresponding to the self-sufficiency period 228 days closest to the user input (220 days) among the combinations that can achieve the self-sufficiency period 220 days. May be displayed in. From such a display, the user can easily grasp 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 the self-sufficiency period of 228 days.

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

FIG. 19 is a diagram showing still another example in which the information output in step S6 of FIG. 2 is displayed on the display unit 30.

FIG. 19 also shows an example in which information on 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-sufficiency days shown in FIG. 10A is input as 300 days. That is, also in the example shown in FIG. 19, it is shown that the user installs (or considers) three types of capacity storage batteries, and what kind of solar cells can achieve 300 days of self-sufficiency. ing.

In FIG. 19, as in the example shown in FIG. 18, an example in which 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 output is output. It is shown. That is, also in FIG. 19, among the combinations that can achieve the self-sufficiency period of 300 days entered by the user, the information (display of 300 days) regarding the combination corresponding to the self-sufficiency period of 300 days closest to the user's input is conspicuously displayed. Has been done.

Further, 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 in which the self-sufficiency period input by the user has a predetermined width. That is, in FIG. 19, information regarding the combination corresponding to the self-sufficiency period (250 to 350 days) having a range of ± 50 days for the self-sufficiency period of 300 days input by the user (display of 250 to 325 days). Is displayed so that it can be distinguished from other displays. With such a display, the user can easily grasp at a glance not only the combinations that can achieve the self-sufficiency period of 300 days but also the information of the combinations around the combination.

Such information suggesting a combination corresponding to the self-sufficiency period in which the self-sufficiency period input by the user has a predetermined width may be set to be displayed by default. In addition, the information suggesting a combination corresponding to the self-sufficiency period having a predetermined width in this way is displayed after asking the user to input the predetermined width (plus or minus how many days) in advance. You may. Further, the predetermined width to be provided in such a self-sufficiency period is not limited to the width of plus or minus several days, and the upper limit and / or the lower limit may be freely set.

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

In recent years, devices that supply hot water using various types of energy are becoming widespread in ordinary households. Therefore, when these water heaters are involved in the power 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 in consideration of such electric power.

In one embodiment, the information processing device 1 may acquire information about 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 visually recognizing the display unit 30 on which the screen as shown in FIG. 20 is displayed. The control unit 10 stores the 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, as shown in FIG. 20, the control unit 10 may display a radio button object on the display unit 30 in order to prompt the user for selection input. In this case, the control unit 10 detects a user's selection input (for example, clicking with a mouse) to the input unit 20. 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 and input the installed user's water heater. For example, as shown in FIG. 20, it is assumed that the user selects and inputs one of three options in response to the instruction "Please select the 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 user's selection input. .. In this case, the control unit 10 stores the information of the water heater selected and input by the user in the storage unit 50 as the information of the installed user's water heater.

Here, it is assumed that the storage unit 50 stores a database in which the installed water heater and the information related to the electric power of the water heater are associated with each other. As a result, the control unit 10 can read out information on the electric power generated by the water heater from the installed water heater. Then, the control unit 10 can add the power output by the user's power generation device and / or the power consumed by the user's load device based on the power information. In one embodiment, even if the above-mentioned database is not stored in the storage unit 50, the control unit 10 receives at least a part of the information of the above-mentioned database from an external device, an external server, or the like via the communication unit 40. You 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 electric energy, it can be regarded as a power generation device that acquires information in step S1 of FIG. Therefore, when the gas water heater is selected, the control unit 10 may add the electric power generated by the water heater as the electric power generated by the power generation device in step S1 of FIG.

Further, for example, some water heaters, such as heat pump water heaters, generate heat energy based on air energy and electric energy. In this case, since the water heater consumes electric energy, it can be regarded as a load device in the step of acquiring the status 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 a hybrid water heater, generate heat energy by using gas and / or electric energy. In this case, since the water heater consumes electric energy, it can be regarded as a load device in the step of acquiring the status 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 as the power consumption in step S3 of FIG.

The example shown in FIG. 20 assumes that the user selects and inputs one of the three types of water heaters. However, for example, the control unit 10 may allow the user to select and input a plurality of water heaters in response to a user who has installed a plurality of water heaters among the three types of water heaters. Further, the control unit 10 may display the display unit 30 asking the user whether or not the installed water heater is present on the screen immediately before the transition to FIG. 20, for example. In this case, when the water heater "Yes" is selected by the user, the control unit 10 may display the screen shown in FIG. 20 on the display unit 30. On the other hand, if the water heater "None" is selected by the user, the control unit 10 may skip the screen shown in FIG.

Further, in general, the output characteristics of a solar cell gradually deteriorate with the passage of power generation time due to various causes such as deterioration over time. Further, in general, the storage battery also gradually deteriorates in storage characteristics and discharge characteristics with the passage of time for storage and discharge due to various causes such as deterioration over time. Therefore, the accuracy of the calculation result can be improved by performing the calculation performed in step S5 of FIG. 2 in consideration of the deterioration of at least one of the solar cell and the storage battery.

For example, it is assumed that the solar cell installed (or under consideration for installation) by the user shows a time change of the characteristics as shown in FIG. 21A. FIG. 21A shows that the output capacity of the solar cell in 2018 is 100% and the output capacity is reduced to 95.5% in 2027, which is the 10th year. Similarly, FIG. 21A shows that the output capacity of the solar cell in 2028 is 95.0%, and the output capacity is reduced to 90.5% in 2037, which is the 20th year.

Further, for example, it is assumed that the storage battery installed (or considered to be installed) by the user shows a time change of the characteristics as shown in FIG. 21B. FIG. 21B shows that the storage capacity of the storage battery has decreased to 55.0% in 2027, which is the 10th year, assuming that the storage capacity of the storage battery in 2018 is 100%. Therefore, in FIG. 21B, the storage battery is replaced in 2028, the output capacity of the storage battery in 2028 is set to 100%, and the storage capacity is reduced to 55.0% again in 2037, which is the 20th year. Shows. It should be noted that the case where the power storage device is not installed after 2028 may be shown.

As described above, by performing the calculation performed in step S5 of FIG. 2 in consideration of the deterioration of at least one of the solar cell and the storage battery, the accuracy of the calculation result performed by the control unit 10 can be improved.

Further, in the above-described embodiment, the storage battery as the power storage device of the user is typically described assuming a stationary storage battery. However, in one embodiment, the user's power storage device is not limited to the stationary storage battery. For example, in one embodiment, the user's power storage device may be an electric vehicle having a built-in storage battery or the like. In recent years, electric vehicles can charge the power of solar cells such as VtoH (Vehicle to Home) or charge the power from a grid. It is also possible to use the electric power discharged from such an electric vehicle.

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

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

Further, the information processing device 1 according to the embodiment is 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.
