A solar power generation device is a device that directly converts light energy from sunlight into electric power, and does not generate carbon dioxide during power generation. Therefore, the solar power generation device has less influence on the surrounding environment than other power generation devices and is used as a clean power generation device. In order to install this solar power generation device, it is necessary to arrange a solar cell module for converting light energy into electric power on the roof surface of a building such as a house.

  Usually, the shape of the roof surface on which the solar cell module is to be arranged varies from building to building. Therefore, the arrangement, that is, the layout of the solar cell module must be designed for each roof surface. 2.

  The module information acquisition unit 12 is a means for acquiring information about a solar cell module used for layout design (hereinafter referred to as “module information”). The module information is acquired from, for example, a module database (hereinafter referred to as “module DB”) that has been databased in advance.

  Module individual information is stored in the module DB for each of a plurality of types of solar cell modules having different outer shapes or outer dimensions. Each module individual information includes model name information, shape information, dimension information, index information, module placement base information, and the like.

  The model name information is information representing a model name assigned to each type of solar cell module.

  The shape information is information representing the shape of the light-receiving side surface of the solar cell module. In the layout design of the solar cell module, solar cell modules having various light receiving side surface shapes are used in order to effectively arrange the solar cell modules in the arrangement target regions on the roof surfaces having various shapes. Specifically, a solar cell module having a rectangular light receiving side surface mainly used in layout design (hereinafter referred to as a “main module”) and a line segment corresponding to a corner in the target region outline are arranged. A solar cell module having a non-rectangular light-receiving side surface (hereinafter referred to as “corner module”) is used.

  This corner module includes, for example, a solar cell module having a light-receiving side surface having a right triangle shape, a pentagon shape, a trapezoidal shape or the like. Here, the pentagonal shape herein refers to a pentagonal shape formed by cutting two acute angle portions in a right triangle by a cut line parallel to the opposite side of the acute angle. Therefore, this shape information is information indicating which shape the light-receiving side surface is, such as a rectangular shape and a pentagonal shape.

  The dimension information is information representing the outer dimension of the light receiving side surface of the solar cell module, and includes height information representing the height direction dimension of the light receiving side surface and width information representing the width direction dimension of the light receiving side surface. 5A and 5B are diagrams for explaining the outer dimensions of the light receiving side surface of the solar cell module. FIG. 5A shows the light receiving side surface S41 of the main module, and FIG. 5B shows a pentagonal corner module. The light receiving side surface S42 is shown.

  A height direction and a width direction are determined in advance on the light receiving side surface of the solar cell module 1 along a line segment of the contour of the light receiving side surface. When the solar cell module is the main module, the dimension information includes height information indicating the height H41 of the solar cell module and width information indicating the width W41 of the solar cell module. When the solar cell module is a corner module, the dimension information includes the height information indicating the height H42 of the solar cell module and the width information indicating the width W42 of the solar cell module, and the inclination of the hypotenuse with respect to the width direction. The hypotenuse angle information representing the angle θ is included.

The module placement base point is a point used as a base point when the solar cell module is placed with respect to the placement target region. For example, as shown in FIG. 5A, the module placement base points include four vertices M1 to M4 in the lower left, lower right, upper right, and upper left, and each of the lower edge, upper edge, left edge, and right edge. Points M5 to M8 are determined in advance, and the module arrangement base point information includes coordinate information representing the positions of these module arrangement base points.

  Such a module DB is created in advance and stored in the hard disk device 113, for example. Moreover, the user can add the module individual information about a new solar cell module with respect to this module DB.

  In the present embodiment, this module DB stores a plurality of module set information in addition to the module individual information described above. The module set information is information that represents a module set that is preliminarily combined with a plurality of types of solar cell modules stored in the module DB based on the contour size of the light receiving side surface. Each module set information includes, for example, model name information of each solar cell module included in the module set.

  This module set includes a building roof set configured by combining main modules and corner modules having the same height dimension, and a plurality of module sets are created in advance for each height dimension.

  For example, a set for a dormitory roof has a height dimension of H and a width dimension of W1, W2,..., Wm (where W1> W2> ...> Wm), where m is 2 (Integer above) number of main modules, the height dimension is H, the width dimension is Wz (Wz is equal to one of the width dimensions of the main module), and the lengths of the cut lines are L1, L2, And one corner module having a pentagonal shape with the inclination angle of the hypotenuse being θ.

  The module information acquisition unit 12 according to the present embodiment acquires module information of the solar cell modules constituting the specified module set from the module DB when the module set to be used for layout design is specified by the user. .

  Based on the area information of the arrangement target area S2 acquired by the area information acquisition section 11 and the module information of the predetermined solar cell module acquired by the module information acquisition section 12, the layout creation section 13 creates the arrangement target area S2. On the other hand, a layout using a predetermined solar cell module is created.

  FIG. 6 is a block diagram illustrating a configuration of the layout creating unit 13. The layout creation unit 13 includes an area determination unit 131, an area division unit 132, a base point setting unit 133, an index setting unit 134, a module number determination unit 135, and a layout determination unit 136.

  The area determination unit 131 determines whether or not the arrangement target area S2 needs to be divided based on the area information acquired by the area information acquisition unit 11. Specifically, it is determined that it is not necessary to divide when the arrangement target area S2 is rectangular, and it is determined that it is necessary to divide when the arrangement target area S2 is non-rectangular. This determination is performed, for example, based on whether or not the line segments C21 to C24 that form the target region outline C2 include a line segment corresponding to the corner, and there is no need to divide when there is no line segment corresponding to the corner. If there is a line segment corresponding to the corner, it can be determined that it is necessary to divide.

  The area dividing unit 132 acquires the area information and module information acquired by the area information acquiring unit 11 when the area determining unit 131 determines that it is necessary to divide, that is, when the arrangement target area S2 is non-rectangular. Based on the module information of the dormitory roof set acquired by the unit 12, the arrangement target area S2 is divided into a plurality of areas.

  Specifically, for the non-rectangular arrangement target area S2, a layout is performed using a rectangular main area and a corner module only, or a main module and a corner module, in which layout design is performed using only the main module. A non-rectangular corner area to be designed is determined.

  The region dividing unit 132 includes an offset distance calculating unit 132a for calculating an offset distance necessary for determining the main region and the corner region.

  The region dividing method by the region dividing unit 132 will be specifically described. FIG. 7 is a diagram for explaining region division for the trapezoidal arrangement target region S2.

  In addition, as a layout design condition, the lower edge of the solar cell module 1 overlaps with the line segment C21 corresponding to the eave so that the roof inclination direction and the height direction of the solar cell module 1 coincide with each other. It is assumed that a condition is given that

  First, the arrangement | positioning possible area | region S20 which can arrange | position a solar cell module is determined with respect to arrangement | positioning object area | region S2. Specifically, it is determined by calculating the height dimension (that is, the roof inclination direction dimension) of the arrangeable region S20 based on the maximum number of solar cell modules 1 that can be arranged along the roof inclination direction.

  The maximum number that can be arranged is determined by the height dimension Y1 of the arrangement target region S2 and the height dimension H of the solar cell module 1 included in the dormitory roof set. At this time, when it is necessary to separate a predetermined interval between the solar cell modules 1 and 1 adjacent to each other along the roof inclination direction, the predetermined interval is taken into consideration. For example, in the case shown in FIG. 7A, since the predetermined interval is 0 and 3H <Y1 <4H, the maximum number that can be arranged can be obtained as 3.

  Based on the maximum number of pieces that can be arranged thus obtained, the height dimension Y2 of the arrangementable area S20 is calculated. That is, the arrangement possible area S20 is determined as a part of the arrangement target area S2 sandwiched between the line segment C21 and the virtual line U1 offset from the line segment C21 by the distance Y2.

  The remaining area can be determined as the main area S21 by defining the corner areas S22 and S23 necessary for arranging the corner module with respect to the arrangement possible area S20 thus determined.

  Specifically, as shown in FIG. 7B, the intersections of the virtual line U1 and the line segments C23 and C24 corresponding to the corners are set to V1 and V2, and the corner area S22 on the virtual line U1. , S23, when the offset distances T1 and T2 are T1, T2, the distances from the intersections V1 and V2 are separated by the offset distances T1 and T2 inward of the dispositionable area S20 along the virtual line U1. Arrangeable area S20 can be divided into main area S21 and two corner areas S22 and S23 by virtual lines U2 and U3 passing through points Q1 and Q2 and orthogonal to virtual line U1.

  For example, in FIG. 7B, a rectangular area having the vertices at the intersections Q3 and Q4 of the points Q1 and Q2 and the virtual lines U2 and U3 and the line segment C21 is the main area S21, and the point V1 described above. , Q1, Q3, and a trapezoidal region having one end point V3 of the line segment C21 as a vertex is a corner region S22, and the above-mentioned point V2, Q2, Q4 and the other end point V4 of the line segment C21 is a trapezoid. The shape region is the corner region S23.

  As described above, the layout target area S2 is divided into the rectangular main area S21 and the non-rectangular corner areas S22 and S23, so that the layout design of the solar cell module can be performed for each of the areas S21 to S23. . Further, since the rectangular main region S21 can be determined at the time of the region division, as will be described later, the solar cell module for one row when the sum total of the indices specified by the user is maximized or minimized. By determining the number of each, the layout design for the entire main area S21 can be performed.

  Here, an offset distance calculation method by the offset distance calculation unit 132a will be described. FIG. 8 is a diagram for explaining a method of calculating the offset distance T1 shown in FIG. FIG. 8 shows a case where three corner modules 2a to 2c are arranged along a line segment C23 corresponding to a corner so as to correspond to FIG. In addition, each corner module 2a-2c respond | corresponds to one corner module contained in the set for dormitory roofs. Further, when it is not necessary to distinguish the corner modules 2a to 2c, they are referred to as a corner module 2.

  The offset distance T1 is set so that any one of the corner modules 2a to 2c contacts the line segment C23, and the joints of the corner modules 2a to 2c and the main module 1 are aligned (details will be described later). The distance between the aforementioned point V1 and the point Q0 in the corner module 2c adjacent to the virtual line U1 when the corner modules 2a to 2c are arranged in the arrangeable region S20 can be calculated. Here, the point Q0 is an end point that is separated from the hypotenuse side among end points on a cut line parallel to the width direction.

  Specifically, the offset distance T1 includes the inclination angle θ of the hypotenuse of the corner module 2 and the lengths L1 and L2 of each cut line, the height dimension Y2 of the arrangeable region S20, and the inclination angle α of the line segment C23. Can be calculated based on this.

  For example, as shown in FIG. 8A, when the inclination angle α of the line segment C23 is equal to or smaller than the inclination angle θ of the hypotenuse (that is, α ≦ θ), the offset distance T1 is the width direction of the corner module 2. Is equal to the length L1 of the tear line parallel to

  Further, as shown in FIG. 8B, when the inclination angle α of the line segment C23 is larger than the inclination angle θ of the hypotenuse (that is, α> θ), the offset distance T1 is a point V1 on the virtual line U1. Is equal to the sum of the distance X1 separating the corner module 2c and the length L1 of the cut line parallel to the width direction of the corner module 2. This distance X1 is calculated based on the inclination angle θ of the hypotenuse of the corner module 2 and the lengths L1 and L2 of each cut line, the height dimension Y2 of the arrangeable region S20, and the inclination angle α of the line segment C23. Can do.

  By calculating the offset distances T1 and T2 in this way, it is possible to determine the main area 21 while securing an area necessary for arranging the corner module 2. That is, since the minimum area required for arranging the corner module 2 is secured in advance as the corner areas S22 and S23, the maximum area can be secured as the main area S21. That is, it is possible to easily realize a layout design that makes the best use of the size of the arrangement target area S2. In addition, about the non-rectangular corner area | region S22, S23 determined in this way, when the magnitude | size of the corner area is sufficiently larger than the magnitude | size of the solar cell module which should be arrange | positioned, the non-rectangular shape As described above, the area division may be performed on the corner areas S22 and S23.

  The base point setting unit 133 specifies the position of the region placement base point serving as a base point for starting the placement of the solar cell module with respect to the placement target region S2 by designating by the user or according to a predetermined setting. Set. Further, a module arrangement base point in the solar cell module is selected based on the set position of the region arrangement base point.

  The index setting unit 134 sets the type of index used for determining the number of modules in the module number determination unit 135 by being designated by the user or according to a predetermined setting. For example, the maximum output value is set as the index type.

  The module number determination unit 135 sets the area information related to the main area S21 determined by the area dividing unit 132, the module information of the main module included in the laid roof set, and the index type set by the index setting unit 134. Based on this, the number of main modules for one model for one row to be arranged in the row area of the main area S21 is determined.

  As described above, when the main module is arranged in the main area S21, the roof inclination direction of the main area S21 and the height direction of the main module are arranged to coincide with each other.

  Here, the row region of the main region S21 is a region formed by dividing the main region S21 in the roof inclination direction in order to arrange the main modules having the same height dimension for one row. Here, when the horizontal dimension of the main area S21 is Ws and the roof inclination direction dimension is Hs, when the height dimension of the main module included in the laid roof set is Hm, the row area has the roof inclination. This corresponds to a rectangular region having a directional dimension of Hm and a horizontal dimension of Ws.

Hereinafter, a method for determining the number of main modules for each model will be described.
Here, the module set specified by the user includes a dormitory roof including two types of main modules 1a and 1b having a height dimension of Hm and a width dimension of Wa and Wb (Wa> Wb). It is assumed that the maximum output values of the main modules 1a and 1b are Out1a and Out1b.

  In order to determine the number I, J (I and J are integers of 0 or more) of the main modules 1a and 1b for one row, the module number determination unit 135 first sets the main modules that can be arranged to the maximum in the row area. The combination of the numbers I and J of the modules 1a and 1b is calculated. That is, a combination of the numbers I and J that satisfies Ws−Wb <Wa × I + Wb × J ≦ Ws is calculated.

  Next, for each calculated combination, the total output value of the main module for one column (that is, the sum of the maximum output values) is calculated. For example, if the number of main modules 1a and 1b for one row in the mth (where m is a positive integer) number is Im and Jm, the total output value Out_sum of the main modules for one row in the mth combination is , Out_sum = Im × Out1a + Jm × Out1b.

  That is, the total output value Out_sum of the main modules for one column is calculated by the number of combinations, and the number of the main modules for one column that should be arranged in the column region is the number of the total output values Out_sum among them. The numbers I and J of 1a and 1b are determined.

  The above describes the case where a set for a dormitory roof that includes two types of main modules is specified, but when a set for a dormitory roof that includes three or more types of main modules is specified. Even in such a case, the number of main modules for one row to be arranged in the row area can be determined by the same method as described above.

  In the above description, the case where the maximum output value is set as the index type has been described, but another index may be set. Hereinafter, a case where a unit price is set as the type of index will be described.

  Similarly to the above, the module set specified by the user includes two types of main modules 1a and 1b having a height dimension of Hm and a width dimension of Wa and Wb (Wa> Wb). Assume that the unit price of each main module 1a, 1b is Pr1a, Pr1b.

  In the same manner as described above, first, a combination of the numbers I and J of the main modules 1a and 1b that can be arranged to the maximum with respect to the row area is calculated. Next, for each calculated combination, the total price of the main modules for one column (that is, the sum of unit prices) is calculated. For example, if the number of main modules 1a and 1b for one row in the mth combination is Im and Jm, the total price Pr_sum of the main modules for one row in the mth combination is calculated as Pr_sum = Im × Pr1a + Jm × Pr1b. Is done.

  That is, the total price Pr_sum of the main modules for one column is calculated by the number of combinations, and among these, the number of sheets when giving the smallest total price Pr_sum is the main module 1a for one column to be arranged in the column area. 1b is determined as the number I and J of each sheet.

  In the above description, only one type of index is set. However, a plurality of index types may be set to determine the number of main modules for one row to be arranged in the row area. For example, by using a predetermined weighting factor for each index type, it is possible to determine the number of main modules for one row to be arranged in the row area even when a plurality of indicator types are set. it can.

  The layout determining unit 136 determines the main region S21 based on the region arrangement base point and module arrangement base point set by the base point setting unit 133, and the number of main modules for one model in a row determined by the module number determination unit 135. Determine the main module layout for.

  Specifically, first, a layout for one column in the column region of the main region S21 is determined. When determining the layout for one column, for example, in consideration of design, it is determined that a main module having a larger width dimension is arranged toward the center of the column region.

  When the layout for one row is determined in this way, in this embodiment, the layout for the entire main region S21 is determined by arranging the layout for one row in the roof inclination direction of the main region S21. As a result, a layout with joints can be determined in the main region S21. Further, since the number of the main modules for one row is determined so that the sum of the indices is maximized or minimized, the layout of the entire main area S21 is also provided so that the sum of the indices is maximized or minimized. be able to. The layout determined in this way is arranged at a predetermined position in the main area S21 based on the area arrangement base point and the module arrangement base point. FIG. 9 is a diagram illustrating an example of a layout in which joints arranged with respect to the main region S21 are aligned.

  After determining the layout for the main area S21, the layout for the corner areas S22 and S23 is further determined. As in the case of calculating the offset distance, the layout for the corner areas S22 and S23 is such that any one corner module comes into contact with the line segment C23 corresponding to the corner, and the corner module and the main module 1 are jointed. Are arranged in the arrangementable area S20 so that the two are aligned.

  When the layout for the main area S21 and the corner areas S22 and S23 is determined, whether or not an unnecessary interval is formed between the layout of the main area S21 arranged at the predetermined position and the layout for the corner areas S22 and S23. Determine whether. When it is determined that an undesired interval is formed, the layout in the corner areas S22 and S23 is moved to an appropriate position. In this way, the layout when the arrangement target area S2 is non-rectangular is determined. FIG. 10 is a diagram showing an example of a layout arranged with respect to the trapezoidal arrangement target area S2.

  The arrangement information output unit 14 outputs arrangement information related to the layout created by the layout creation unit 13. Specifically, the layout information of the solar cell module with respect to the layout target area S2 and the total output value or the total price related to the layout are displayed on the display 122a or printed on the recording paper by using the printer 122b, thereby arranging the layout information. Is output. As a result, the user can not only confirm the designed layout but also the total output value and total price of the layout.

When the layout is created, the process proceeds to step s4.

  In step s4 (arrangement information output step), the arrangement information output unit 14 outputs arrangement information related to the layout created by the layout creation unit 13. Specifically, one or both of processing for displaying arrangement information on the display 122a and processing for printing on a recording sheet using the printer 122b are executed. When the output of the arrangement information is completed, the process proceeds to step s5.

  In step s5, the calculation process for layout design is completed. In this way, the user can easily confirm the output arrangement information.

  FIG. 12 is a flowchart showing in detail the layout creation process in step s3 in FIG. When step s2 in FIG. 11 is completed, a layout creation process is started in step s30.

  In step s31 (region determination step), the region determination unit 131 determines whether or not the placement target region S2 needs to be divided. If it is determined that division is necessary, the process proceeds to step s32.

  In step s32 (region dividing step), the region dividing unit 132 determines the main region S21 and the corner regions S22 and S23 for the arrangement target region S2. When the main area S21 and the corner areas S22 and S23 are determined, the process proceeds to step s33.

  In step s33 (base point setting step), the base point setting unit 133 sets a region placement base point and a module placement base point. When the region arrangement base point and the module arrangement base point are set, the process proceeds to step s34.

  In step s34 (index setting step), the index setting unit 134 sets the type of index used by the module number determining unit 135 to determine the number of modules. When the index type is set, the process proceeds to step s35.

  In step s35 (module number determining step), the module number determining unit 135 determines the number of main modules for one model to be arranged in the row area of the main area S21. When the number of modules is determined, the process proceeds to step s36.

  In step s36 (layout determining step), the layout determining unit 136 determines the layout of the solar cell module with respect to the arrangement target region S2. When the layout is determined, the process proceeds to step s37. In step s37, the layout creation process is completed. When the layout creation process is completed, the arrangement information output process in step s4 in FIG. 7 is started.

  As described above, when designing the layout of a solar cell module using a plurality of types of solar cell modules having different outer shapes or outer dimensions for the non-rectangular arrangement target region S2, the layout The creation unit 13 divides the arrangement target area S2 into a rectangular main area S21 and non-rectangular corner areas S22 and S23, and uses only a rectangular main module for the divided main area S21.
