In addition, even if the annual power generation amount can be estimated by the method described in Patent Document 3, it is not possible to know the various consideration factors as described above, so this is utilized for those who plan to introduce the solar power generation system. It is considered impossible.

Step 3 is roughly divided into step 4 for “result display”, and the simulation process is executed along the flow of step 1 to step 4.

<Step 1>
First, step 1 for inputting “installation schedule information” will be described.

The screen SG1 in FIG. 8 shows an example of the information input / display screen in the above step 1. As shown in FIG. 8, the following information is used as the installation schedule information A that is an input parameter for the charge simulation. There is.

A3. Installation type (base installation type, roof installation type, healthy integrated type)
A4. Panel information (nominal maximum output (nominal value of rated capacity), panel width, panel length)
Among these installation schedule information A1 to A4, the simulation means 15 has measured the location information A1 in the case of the tablet-type terminal 100 equipped with the GPS positioning unit 160. The location information obtained from the position (and map data) is automatically set as an input parameter for simulation.

  When measuring “the azimuth angle of the roof and the inclination angle of the roof”, the user places the tablet terminal 100 on the surface of the actual roof on which the solar panel is installed, and in that state, measures on the home screen SGH. Measurement is started by touch operation or remote operation of a start button (START button G41A in this example), and measurement is stopped by touch operation or remote operation of a measurement stop button (STOP button).

  When the measurement data output means 14 detects a measurement stop operation signal, the measurement data of the inclination angle and azimuth angle of the roof at that time is linked to the identification information of the roof surface (in this example, “roof 1”). Store in the storage unit 120. When installing a solar panel on another surface (for example, the other inclined surface of the gable roof), after the user instructs measurement of the next installation surface by touch operation or remote operation of the “roof addition button” G52 The tablet terminal 100 is placed on the roof surface, and the next installation surface (“roof 2”) is measured in the same manner. When the simulation is started after the measurement is completed, the user presses the simulation start button G53. In this example, the home screen SGH in FIG. 9 is switched to the screen SG1 in FIG. 8 by operating the simulation start button G53.

  In the present embodiment, the first moving image indicating the tilted state of the Y axis with respect to the horizontal plane uses the terminal appearance image G11 indicating the side appearance of the tablet terminal 100 in the screen example of FIG. On the other hand, in the example of the first moving image (G10A) in FIG. 9, a linear roof image G11A schematically showing the installation surface of the solar panel (in this example, “roof”) is used. In addition, the second moving image indicating the tilted state of the X axis with respect to the horizontal plane is a moving image G20 representing a bar-shaped level in the screen example of FIG. 6, whereas in the screen example of FIG. 9, a circular level Is represented as a moving image G20A. The START button G41A in FIG. 9 corresponds to the measurement start button G41 in FIG. 6, and is switched to the STOP button after touching the START button G41.

  The display forms such as the first and second moving images described above are not limited to those shown in FIGS. 6 and 9. The display forms shown in FIG. Alternatively, an embodiment adopting the display form of FIG. 6 may be adopted.

  Next, a method for setting other information of the installation schedule information A will be described.

  For example, in the case of the tablet-type terminal 100 equipped with the GPS positioning unit 160, the simulation unit 15 uses the installation surface information (the size of the roof and the shape of the roof) that is an element of the building detached information A2. Based on the current position measured by the GPS positioning unit 160 and aerial photograph data or satellite photograph data corresponding to the current position obtained from a predetermined website (such as a map data providing site), the size of the roof and the shape of the roof are determined. The information shown is automatically set as an input parameter for simulation. Specifically, for example, image data of an aerial photograph or satellite photograph is processed to extract a roof outline, and based on the outline information and inclination angle (θy, θx) information, the roof size and roof Find the shape. On the other hand, in the case of the tablet-type terminal 100 not equipped with the GPS positioning unit 160, the shape of the roof selected from the schematic diagram on the screen (gable, dormitory, single stream, occupancy, square, etc.) Information on the size of the roof selected or input on the screen is set as an input parameter for the simulation.

  For the installation type A3, the installation type selected on the screen is set as an input parameter for the simulation. For the panel information A4, the manufacturer (and model name) selected in step 1 (or step 3 described later) is set. Panel information is obtained from the storage unit 130, and the panel information is set as an input parameter for simulation.

<Step 2>
Next, step 2 for inputting information on “about utility cost” will be described.

The screen SG2 in FIG. 10 shows an example of the information input / display screen in the above step 2. As shown in FIG. 10, the information B of the utility cost as the input parameter of the charge simulation is as follows. There is information.
(Information about utility bills B)
B1. Basic fee / Ampere B2. Current utility costs (monthly electricity bills, electric energy)
B3. System charge (price of photovoltaic system)
B4. Subsidy B5. Payment terms (cash payment, installments (with down payment), installments (without down payment))
Among these installation schedule information B1 to B5, for information B1, B2, and B5, information selected or input on the screen is set as an input parameter for simulation. The basic charge / ampere information B1 varies depending on the electric power company. That is, there are two systems, an amperage system and a minimum charge system, for each electric power company. In the case of an amperage system, for example, it can be obtained from a contracted amperage selected and input on the screen. At that time, the simulation means 15 automatically identifies the power company from the location information A2 of the building to be installed, and sets the charge of the power company stored in advance corresponding to the power company as a basic charge. .

  For the system fee B3, the simulation unit 15 sets the system fee of the manufacturer selected in step 1 (or step 3 described later) (previously stored fee for the solar power generation system of the manufacturer) as an input parameter for the simulation. To do. Moreover, since there are various forms for the subsidy B4 depending on each local government, the subsidy B4 is set using subsidies and subsidies for each local government stored in advance. In the present embodiment, based on the location A1 of the building to be installed set in step 1, the local government to which the prospective introduction person belongs is automatically determined, and subsidies / subsidies stored in advance corresponding to the local government Obtain gold information and set that information as input parameters for the simulation.

<Step 3>
Next, step 3 for inputting and explaining information on “charge” will be described.

  When simulating what the current electricity bill will be in the future when a solar power generation system is introduced, it is important to consider the lifestyle patterns of the family.

  For example, the electricity price menu contracted with an electric power company includes a metered light, a light by time zone (8 hours type at night, a 10 hour type at night), late-night power, and a light by season. When a solar power generation system is introduced, for example, by using a lighting contract by time zone, during the daytime when the unit price of electricity is high, solar power is used to supply electricity and the surplus of solar power generation is sold to an electric power company. At night, if the pattern of purchasing and using cheap late-night electricity is used, there will be a period (called “depreciable years”) when profits from power sales will occur after the cost of introducing the system is recovered in the future. It will be faster.

  In the present embodiment, the amount of electricity used for each time zone after the introduction of the solar power generation system is calculated according to the family life pattern, and the breakdown of the purchased power after the system introduction (by time zone (for example, in the morning, (Breakdown of electricity purchase charges for day, night, and night)), breakdown of electricity sales, comparison of monthly electricity charges before and after introduction, time transition of utility costs of the building to be installed, including the period of depreciation, The simulation results are shown in graphs and tables.

  Here, a method for specifying a family life pattern and a method for calculating the amount of electricity used for each time zone will be described.

  Screen SG3 of FIG. 11 shows an example of an information input screen of “family life pattern”. As shown in the figure, the four zones of morning, noon, evening, and night are divided into time zones, and the time zone Shown is an example of classifying “family life patterns” into three patterns of “intermediate type”, “day type”, and “night type” according to the percentage of electricity usage (average value of measured values of family life model) ing.

  In other words, the table indicating the “family life pattern” in the screen SG3 is “day type”, “night type”, “intermediate type”, and the respective types as described in the explanatory text on the screen SG3. The ratio of the life model is calculated based on the ratio of electricity used in each time zone.

  The simulation means 15 can select any one of “day type”, “night type”, and “intermediate type” by a touch operation by a user (planned introduction person or person in charge such as a sales agent) on the screen SG3 of FIG. When selected, “current utility cost” (contract contents, contract ampere, basic charge, monthly average electricity bill, etc.) is displayed at the bottom of the screen SG3, and when the page turning operation is performed, the screen of FIG. Switch to SG4 and display “Current electricity consumption by time zone” and the like on the screen SG4.

  Screen SG4 illustrated in FIG. 12 is an example in which “electricity cost of metered lamp” is displayed in the upper part of the screen, and “current electricity usage by time zone” is displayed in the lower part of the screen. Electricity consumption by time zone calculated based on the ratio by time zone corresponding to the life pattern selected by the user and the electricity unit price by time zone (the electricity unit price of the power company) stored in advance is there.

  When the page turning operation is performed on the screen SG4 in FIG. 12, the simulation unit 15 switches to the screen SG5 in FIG.

  Here, the design of the photovoltaic power generation system will be described before the description of the screen SG5.

  When introducing a solar power generation system, consider the optimal manufacturer, optimal panel layout, and depreciation period from the viewpoints of installation cost, installation effect (cost of reducing electricity bills), loan burden, etc. Is desirable.

  In the present embodiment, the simulation means 15 explains to the introductory person various study elements such as the depreciation years and the reduction costs with easy-to-understand schematic diagrams and explanatory texts, and which manufacturer's solar Whether the photovoltaic system is optimal, how many panels are optimally installed on which side of the roof, when is the time when profits from power sales are generated, and the amount of power generation and power saving effect after introduction is actually The simulation results, such as what will happen, are displayed on the screen.

  Screen SG5 illustrated by FIG. 13 has shown an example of screen SG5 for examination regarding the design of a solar power generation system. As shown in FIG. 13, the main examination factors regarding the design of the photovoltaic power generation system include panel information (manufacturer, panel product number, number of panels, maximum output, annual estimated power generation amount), depreciation years, and system introduction cost. .

  The simulation means 15 continues to pay the utility bill as it is based on input parameters such as panel information (or panel information set in step 1) such as the manufacturer selected on the screen SG5 of FIG. Compare the accumulation of electricity costs when installing a solar power generation system, and as shown in the lower part of the screen SG5 in FIG. 13, a graph representing the comparison between the two, with the accumulation of electricity charges on the vertical axis and the number of years on the horizontal axis. indicate.

  In the graph of FIG. 13, the solid line indicates “cumulative electricity bill” when continuing to pay utility costs as it is, and the broken line indicates “system cost + cumulative electricity bill” when a solar power generation system is installed, The intersection between the solid line and the broken line indicates “amortization years”, and the opening between the solid line and the broken line indicates “reduction cost”.

  The prospective introduction person appropriately changes the design elements (manufacturer, number of panels, etc.) of the photovoltaic power generation system while viewing the graph on the screen SG5, and determines the optimum manufacturer, number of panels, and the like. Then, the determined information is set as a simulation input parameter and stored in the storage unit 130.

<Step 4>
Next, step 4 for “result display” will be described.

  The simulation means 15 includes information on the input parameters set in Steps 1 to 3 and information stored in the database in advance (catalog information for each manufacturer of the solar power generation system and peripheral devices, power unit price for each power company, etc. Before and after the introduction of the photovoltaic power generation system based on the information on electricity bill calculation elements, standard weather data, subsidy data of local governments (country data of countries, prefectures, municipalities, and predetermined electricity bill calculation algorithms) The electricity bill is calculated, and various simulation results are automatically created and presented to the prospective person in graphs and tables.

  The standard weather data is standard weather data (public data) obtained from a website of a predetermined organization (for example, the Japan Weather Association), and the standard weather data is created for a heat load simulation for calculating an energy saving effect. It consists of a data group for every hour and one year for seven items of temperature, absolute humidity, direct solar radiation, sky solar radiation, cloud cover, wind direction, and wind speed.

Calculate the power generation amount and the predicted value of the electricity cost after installing the solar power system by substituting the elements of the power generation amount, the rated capacity value of the solar panel, etc. into the predetermined calculation formula. ing.
