  The solar cell module includes a solar cell panel and a module frame attached to an edge portion of the panel (see, for example, Patent Document 1). As disclosed in Patent Document 1, a solar cell module generally has a substantially rectangular shape in plan view. For example, when a rectangular solar cell module is installed on a dormitory roof, a square roof, or the like, A space where a module cannot be installed is formed in the vicinity of the end in the girder direction. Accordingly, solar cell modules having a shape that can be installed in such a space (for example, a substantially pentagonal shape in plan view) have been developed.

Japanese Patent Laying-Open No. 2015-195663

  By the way, when the shape of the solar cell module is a pentagon, the number of members constituting the module is increased as compared with the rectangular shape, and there is a problem that the member management becomes complicated. Moreover, it is also assumed that the manufacturing cost of the solar power generation device comprised of a plurality of solar cell modules increases due to an increase in variations in the shape of the solar cell modules.

  A solar cell module that is one embodiment of the present disclosure includes a first side and a second side that are substantially orthogonal to each other and have substantially the same length, a third side that is substantially orthogonal to the first side, and a third side A solar cell panel having a substantially pentagonal shape in plan view, having a fourth side substantially the same as the side and substantially perpendicular to the second side, and an oblique side connecting the third and fourth sides, and a solar cell panel And a module frame attached to the end edge portion.

  A photovoltaic power generation apparatus according to an embodiment of the present disclosure includes a solar cell module array along a girder direction of a roof, including the solar cell module having a substantially pentagonal shape in plan view and a solar cell module having a substantially rectangular shape in plan view. The solar cell modules having a substantially pentagonal shape in plan view are respectively provided at the ends of the rows of the solar cell modules.

  According to the solar cell module having a substantially pentagonal shape in plan view which is one aspect of the present disclosure, it is possible to share the members in the solar power generation device, and it is possible to reduce the member management burden and reduce the cost. Moreover, it is also possible to share a member in each of the solar cell modules.

It is a figure which shows the solar power generation device which is an example of embodiment. It is a top view of the solar cell module which is an example of embodiment. FIG. 3 is a sectional view taken along line AA in FIG. 2. It is a top view of the solar cell module which is an example of embodiment, Comprising: It is a figure which shows the state which removed the module frame from the solar cell panel. It is the B section enlarged view of FIG. It is a top view of the solar cell module which is another example of embodiment. It is a top view of the solar cell module which is another example of embodiment. It is a top view of the solar cell module which is a reference example.

  According to the solar cell module having a substantially pentagonal shape in plan view, which is an aspect of the present disclosure, it is possible to share the members in the solar power generation device as described above.

Moreover, it is also possible to make the solar cell panel itself and the module frame common among the modules.

  Further, the constituent members can be shared in one solar cell module. The module frame includes the above-described frames. For example, the angle formed between the outer peripheral side surface of the third frame and each end surface is substantially the same, and the angle formed between the outer peripheral side surface of the fourth frame and each end surface is approximately the same. If they are the same, many of the frames can be shared. In particular, when the angle formed between the outer peripheral side surface of the oblique side frame and each end surface is about 90 °, and the angle formed between the outer peripheral side surface of each other frame and each end surface is about 45 °, a larger number of frames can be obtained. Can be shared.

Hereinafter, an exemplary embodiment will be described in detail with reference to the accompanying drawings.
The drawings are all schematically described, and the dimensional ratios of the components drawn in the drawings should be determined in consideration of the following description. It is assumed from the beginning that a plurality of embodiments described below are appropriately combined.

  In this specification, the “up and down direction” of the module frame means a direction along the thickness direction of the solar cell panel, and the light receiving surface side of the solar cell panel is “up”. Further, the plan view means a state where the panel or the like is viewed from a direction perpendicular to the light receiving surface of the solar cell panel unless otherwise specified. Here, the light receiving surface of the solar cell panel is a surface on which sunlight is mainly incident, and more than 50% to 100% of the sunlight incident on the panel is incident from the light receiving surface. In addition, in the present specification, the description of “substantially **” is intended to include the case where substantially the same is recognized as substantially the same as the case where substantially the same is described as an example.

  FIG. 1 is a diagram illustrating a solar power generation device 50 that is an example of an embodiment. As shown in FIG. 1, the solar power generation device 50 includes a plurality of solar cell modules 10 </ b> A, 10 </ b> B, and 51. The roof 53 on which the solar power generation device 50 is installed is, for example, a dormitory roof, and the solar power generation device 50 is installed on a trapezoidal portion of the roof 53. However, the solar power generation device 50 may be installed in the triangular part of the roof 53, and may be installed in places other than a dormitory roof, such as a square roof. The solar power generation device 50 includes a frame for attaching each module to the roof 53, a fixing bracket (not shown), and the like.

  The solar power generation device 50 includes a row 52 of solar cell modules along the girder direction of the roof 53. The solar cell module row 52 (hereinafter sometimes simply referred to as “row 52”) includes solar cell modules 10A and 10B having a substantially pentagonal shape in plan view and solar cell modules 51 having a substantially rectangular shape in plan view. Solar cell modules 10 </ b> A and 10 </ b> B are provided at the ends of row 52, respectively. That is, the column 52 is configured by one solar cell module 10A, 10B and the solar cell module 51 arranged between the solar cell modules 10A, 10B arranged in a row.

  The solar power generation device 50 generally has a plurality of rows 52. In the example shown in FIG. 1, the number of the solar cell modules 51 is different in each row, and the length of the row 52 increases as the length of the roof 53 in the girder direction increases from the ridge portion 54 to the eave portion 55 of the roof 53. Yes. The plurality of solar cell modules 10A and 10B constituting each row 52 has a diagonal side frame 13e (see FIG. 2) (to be described later) of each module at the corner ridge portion 56 in more detail along the corner ridge portion 56 of the roof 53. It is arranged so that it may go along. The solar cell module 51 includes, for example, a substantially rectangular solar cell panel in plan view and a module frame attached to the edge of the panel, and is arranged in a state where the long side direction is substantially parallel to the girder direction of the roof 53. Has been. A conventionally well-known thing can be applied to the solar cell module 51.

  Since the solar power generation device 50 includes the solar cell modules 10A and 10B having a substantially pentagonal shape in plan view as described above, when only the solar cell module 51 having a substantially rectangular shape in plan view is used, the module 53 cannot be installed. The space near the end in the girder direction can be used effectively. By installing the solar cell modules 10 </ b> A and 10 </ b> B in such a space, the module installation area on the roof 53 can be increased and the amount of power generation can be increased.

  Although mentioned later in detail, in this embodiment, the same thing can be used for solar cell module 10A, 10B. That is, the solar cell modules 10A and 10B are different only in the direction of attachment to the roof 53. The solar cell module 10A can be used as the solar cell module 10B and the solar cell module 10B can be used as the solar cell module 10A. The solar cell modules 51 are the same, and the solar power generation device 50 can be composed of two types of solar cell modules.

  2 is a plan view of the solar cell module 10A, FIG. 3 is a sectional view taken along line AA in FIG. 2, and FIG. 4 is a diagram showing a state in which the module frame 13 is removed from the solar cell panel 11. As shown in FIGS. 2 to 4, the solar cell module 10 </ b> A includes a solar cell panel 11 and a module frame 13 attached to an edge portion of the panel. The solar battery panel 11 has a substantially pentagonal shape in plan view, and has, for example, a structure in which a plurality of solar battery cells 12 are sandwiched between two protective members such as a glass substrate and two resin sheets functioning as a sealing material. . The module frame 13 is a member that protects the edge of the solar cell panel 11 and is used for fixing the solar cell module 10A to the roof 53, for example.

  The solar cell panel 11 having a substantially pentagonal shape in plan view includes sides 11a and 11b (first and second sides) substantially orthogonal to each other, a side 11c (third side) substantially orthogonal to the side 11a, and a side 11b. It has a side 11d (fourth side) that is substantially orthogonal, and a hypotenuse 11e that connects the sides 11c and 11d. That is, the side 11b is substantially orthogonal to one end of the side 11a, and the side 11c is substantially orthogonal to the other end of the side 11a. The sides 11a and 11d are substantially parallel to each other, and the sides 11b and 11c are substantially parallel to each other.

Further, the length L _11a of the side _11a is substantially the same as the length L _11b of the side 11b, and the length L _11c of the side _11c is substantially the same as the length L _11d of the side 11d. The angle formed between the side 11a and the side 11b, the angle formed between the side 11a and the side 11c, and the angle formed between the side 11b and the side 11d are all about 90 °. The angle formed between the side 11c and the hypotenuse 11e and the angle formed between the side 11d and the hypotenuse 11e are both about 135 °, and the hypotenuse 11e is inclined at an angle of about 45 ° with respect to the sides 11a and 11b. ing. In this case, the same glass substrate, resin sheet, etc. can be used for each solar cell panel 11 which comprises solar cell module 10A, 10B.

  In the example shown in FIG. 2, the arrangement of the plurality of solar cells 12 constituting the solar cell panel 11 passes through the intersection of the side 11a and the side 11b of the solar cell panel 11 in a plan view and is drawn vertically to the oblique side 11e. It is symmetrical with respect to the line α. Moreover, the planar view shape of the solar cell panel 11 is also bilaterally symmetrical with respect to the virtual line α. In this case, the same solar cell panel 11 can be used in the solar cell modules 10A and 10B, and the management burden of the members can be further reduced. In addition, as for the solar cell panel 11, the planar view shape of the whole panel containing the wiring material (not shown) etc. which connect the photovoltaic cells 12 may be bilaterally symmetrical with respect to virtual line (alpha).

  The module frame 13 is composed of a plurality of frames. Each frame is a long member obtained by extruding a metal material such as aluminum. As will be described later in detail, it is preferable that the frames have substantially the same width and have a hollow structure. And each frame is attached to the edge part of the solar cell panel 11 in the state which faced the end surfaces formed in the longitudinal direction both ends. The end faces of adjacent frames are preferably in contact with each other. Each frame is produced, for example, by cutting the extruded product in the width direction at an angle at which the end faces coincide.

  The module frame 13 includes frames 13a and 13b (first and second frames) attached along the sides 11a and 11b of the solar cell panel 11, respectively. Furthermore, a frame 13c (third frame) attached along the side 11c, a frame 13d (fourth frame) attached along the side 11d, and an oblique side frame 13e attached along the oblique side 11e are included.

  The frame 13a is substantially orthogonal to the frames 13b and 13c and is disposed substantially parallel to the frame 13d. The frame 13a is connected to the frames 13b and 13c with each end surface 15a (see FIG. 4) in contact with the end surface 15b of the frame 13b and the end surface 15c of the frame 13c. The frame 13b is substantially orthogonal to the frames 13a and 13d and is disposed substantially parallel to the frame 13c. The frame 13b is connected to the frame 13c in a state where the end surface 15b is in contact with the end surface 15d of the frame 13d. The oblique side frame 13e is connected to the frames 13c and 13d in a state where the end surfaces 15e are in contact with the end surface 15c of the frame 13c and the end surface 15d of the frame 13d, respectively.

  In the present embodiment, notches 14 for flowing rainwater or the like are provided at both ends in the longitudinal direction of the frames 13a and 13b. The notch 14 is formed, for example, by cutting out a first flange 21 described later. As will be described later, the first flange portion 21 of the frames 13a and 13b covers the edge of the light receiving surface of the solar cell panel 11, but the upper ends of the frames 13a and 13b and the solar cell panel are provided in the portion where the notch 14 is provided. 11 light receiving surfaces are substantially the same height. For this reason, for example, rainwater flowing on the light receiving surface of the solar cell panel 11 flows from the light receiving surface through the notch 14. The cutout 14 may be provided only in the frame 13b located closest to the eaves 55, but is preferably provided in the frames 13a and 13b in order to make the frames 13a and 13b common. Further, the frames 13a and 13b preferably have a drain hole (not shown) in the main body portion 20 described later.

  As shown in FIG. 3, the frame 13 a includes a main body portion 20 and a first flange portion 21 that is provided on the upper surface of the main body portion 20 and holds an edge portion of the solar cell panel 11. Although the frame 13a is illustrated in FIG. 3, in this embodiment, the other frames also have the same cross-sectional shape as the frame 13a, and the width and the vertical length of each frame are substantially the same. The first flange portion 21 extends, for example, straight from the outside of the main body portion 20, and is bent inwardly in the middle of the module to be formed in a substantially L shape. An inner groove 22 into which an end edge portion of the solar cell panel 11 can be inserted is formed between the upper surface of the main body portion 20 and the first flange portion 21. In other words, the first flange 21 is erected on the main body 20 with a gap in which the end edge of the solar cell panel 11 can be inserted between the first flange 21 and the main body 20.

  The frame 13a has, for example, a second flange 23 that extends straight downward from the inside of the main body 20 and is bent in the middle of the module and formed in a substantially L shape. An outer groove 24 is formed between the lower surface of the main body 20 and the second flange 23. For example, a fixing fitting for fixing the solar cell module 10 to the roof 53 is inserted into the outer groove 24. In the example shown in FIG. 3, an inner collar part 25 extending to the opposite side (inside the module) to the second collar part 23 is provided at the lower end of the frame 13a. The inner collar portion 25 is used for fixing the solar cell module 10 to the roof 53 in the same manner as the outer groove 24, for example. The frame 13a is preferably extruded. In this case, the main body portion 20 and the like are continuously formed in the longitudinal direction of the frame.

  The main body 20 preferably has a hollow, substantially quadrangular prism shape from the viewpoints of weight reduction, material cost reduction, rigidity improvement, and the like. Each frame having a hollow structure is fixed to each other using the hollow portion. For example, the frames 13a and 13c can be connected by inserting one end side of a corner piece (not shown) into the hollow portion of the frame 13a and inserting the other end side into the frame 13c.

As shown in FIG. 4, the frames 13a and 13b have substantially the same length (L _13a ≈L _13b ). The frames 13c and 13d have substantially the same length (L _13c ≈L _13d ). The length L _13e hypotenuse frame 13e, it is preferable longest among the frames forming the module frame 13. The length of each frame is generally substantially the same as the length of each corresponding side of the solar cell panel 11. For example, the length L _13a of the frame 13a is substantially the same as the length L _11a of the side 11a.

FIG. 5 is an enlarged view of a portion B in FIG. As shown in FIGS. 4 and 5, the angle θ _13c formed by the outer peripheral side surface 16c of the frame 13c and the one end surface 15c is equal to the first end surface 15e of the oblique side frame 13e butted against the one end surface 15c and the frame 13c. It is preferable that the angle θ _13e formed by the outer peripheral side surface 16e is different. Here, the outer peripheral side surface means the side surface (surface along the vertical direction) of each frame along the outer periphery of the module frame 13. When the angles θ _13c and θ _13e are different angles, the area of the end face with a small angle is larger than the area of the end face with a large angle, and a part of the end face with a small angle does not face the end face with a large angle. Overhangs inside the module.

In the present embodiment, the angle θ _13c is smaller than the angle θ _13e , and a part of the end surface 15c of the frame 13c protrudes from the position facing the end surface 15e to the inside of the module. And the hollow part of the main-body part 20 is exposed from the part which the end surface 15c protruded. Rainwater or the like may enter the hollow portion of the frame, and when rainwater or the like enters, it is preferable to quickly drain it. The angle theta _13c to expose the hollow portion of the frame 13c is made smaller than the angle theta _13e, easily it is discharged from the portion rainwater having entered into the frame 13c is exposed, rainwater long time frame 13c Accumulation can be suppressed.

In addition, an angle θ _13d formed by the outer peripheral side surface 16d of the frame 13d and the one end surface 15d is an angle formed by the second end surface 15e of the oblique side frame 13e that abuts the one end surface 15d and the outer peripheral side surface 16e of the frame. It is preferable that it is different from θ _13e . In the present embodiment, the angle θ _13d is smaller than the angle θ _13e , and a part of the end surface 15d of the frame 13d protrudes from the position facing the end surface 15e to the inside of the module. In this case, it is assumed that rainwater or the like is easily changed from the exposed hollow portion of the main body 20 into the frame 13d. However, since the frame 13d is arranged along the direction of the roof 53, it has entered. Rainwater or the like is easily discharged from the other end face 15d side. Rainwater or the like discharged from the other end surface 15d is discharged from the solar cell module 10A through, for example, a drain hole formed in the main body 20 of the frame 13b.

An angle θ _13c formed by the outer peripheral side surface 16c of the frame 13c and each end surface 15c may be different from each other, but is preferably substantially the same. Furthermore, the angle theta _13c is preferably at an angle theta _13d substantially the same formed by the outer peripheral side surface 16d and the end face 15d of the frame 13d. That is, it is preferable that the angle θ _13d of each end face 15d is substantially the same. Since the length L _13c of the frame _13c and the length L _13d of the frame 13d are substantially the same, the frames 13c and 13d can be made common if the angles θ _13c and θ _13d are substantially the same.

Specifically, the angles θ _13c and θ _13d are preferably about 45 °, and the angle θ _13e is preferably about 90 °. The angle θ _13a formed between the outer peripheral side surface 16a of the frame 13a and each end surface 15a and the angle θ _13b formed between the outer peripheral side surface 16b of the frame 13b and each end surface 15b are preferably about 45 °. That is, the preferable angle of each end face is an angle θ _13e of about 90 °, and the angle formed between the outer peripheral side surface of each frame excluding the hypotenuse frame 13e and each end face is about 45 °. In this case, in addition to the frames 13c and 13d, the frames 13a and 13b can be shared.

  Here, the effect of the solar cell module 10A having the above-described configuration will be described in detail in comparison with the solar cell modules 100 and 200 of the reference example shown in FIG. The solar cell modules 100 and 200 constitute one solar power generation device similarly to the solar cell modules 10A and 10B.

  The solar cell panel 101 of the solar cell module 100 shown in FIG. 8 is a solar cell module 10 </ b> A solar cell module 10 </ b> A in that the sides 101 a and 101 b are substantially orthogonal and have substantially the same length in plan view. Common with battery panel 11. On the other hand, the length of the side 101c is different from the length of the side 101d, and is different from the solar cell panel 11 in that the side 101d is longer than the side 101c. The length of the frame 103d is longer than the length of the frame 103c. Similarly, in the solar cell module 200, the sides 201a and 201b of the solar cell panel 201 are substantially orthogonal to each other and have substantially the same length, but the side 201d is longer than the side 201c and the frame 203d is longer than the frame 203c.

Furthermore, in the solar cell module 100, an angle θ _103c formed by one end surface 105c of the frame 103c that abuts the end surface 105e of the oblique frame 103e and the outer peripheral side surface 106c, and an angle θ _103e formed by the end surface 105e and the outer peripheral side surface 106e Are substantially the same. Further, the angle θ _103d formed by one end surface 105d of the frame 103d that abuts the end surface 105e of the oblique frame 103e and the outer peripheral side surface 106d is substantially the same as the angle θ _103e . The angle of the other end face is about 45 °. Similarly, in the solar cell module 200, the angle θ _203c of one end face 205c, the angle θ _203d of one end face 205d, and the angle θ _203e of each end face 205e are substantially the same.

  In the case of the solar cell modules 100 and 200, the lengths of the frames 103a, 103b, 203a, and 203b and the angles of the respective end faces are substantially the same, so that they can be shared, and for the same reason, the hypotenuse frames 103e and 203e. Can also be shared. However, since the frames 103c and 203c and the frames 103d and 203d have different lengths, and the angles of the two end faces in each frame are also different, they cannot be shared. For this reason, six types of frames are required. Further, even if the solar cell panel 101 shown in FIG. 8A is rotated 90 ° to the right, the solar cell panel 101 does not match the shape of the solar cell panel 201 shown in FIG. It is necessary to prepare the glass substrate, and it is difficult to make common the glass substrate and the like constituting each panel.

On the other hand, in the case of the solar cell module 10A, since the length is L _13c ≈L _13d and the angles of the end faces are θ _13c ≈θ _13d , the frames 13c and 13d can be shared. As for the frames 13a and 13b, the length is L _13a ≈L _13b , the angle of each end face is θ _13a ≈θ _13b , and θ _13a ≈θ _13b ≈θ _13c ≈θ _13d , so in the case of the solar cell module 10A Three types of frames may be prepared. Furthermore, since the solar cell module 10A matches the shape of the solar cell module 10B when rotated 90 ° to the right, it can be used as the solar cell module 10B as described above. That is, in the solar cell modules 10A and 10B, only three types of frames and one type of solar cell panel 11 need be prepared, and the number of members can be greatly reduced as compared with the case of the solar cell modules 100 and 200. As described above, the members can be made common in each of the solar cell modules 10A and 10B, and the member management burden in the solar power generation device 50 can be reduced, and the cost can be reduced.

  The above-described embodiment can be appropriately changed in design without departing from the object of the present disclosure. 6 and 7 show another example (modified example) of the embodiment.

  The solar cell module 30 illustrated in FIG. 6 differs from the solar cell module 10A in that the arrangement of the solar cells 12 is not symmetrical with respect to the virtual line α. In the solar battery panel 31 of the solar battery module 30, two rows of the solar battery cells 12 adjacent to the frame along the frame 13b are configured by the same number of solar battery cells 12. And the big clearance gap is provided between the photovoltaic cell 12 and the flame | frame 13a, and between the photovoltaic cell 12 and the flame | frame 13d. In this gap, for example, a wiring material or the like for connecting the strings of the solar battery cells 12 can be arranged.

  The solar cell module 30 may be used in place of the solar cell modules 10 </ b> A and 10 </ b> B constituting the row 52 of the solar power generation device 50. However, in consideration of the appearance of the solar power generation device 50, it is preferable that the cell arrangement of the solar cell modules arranged at both ends of the row 52 is symmetrical with respect to the direction of the roof 53. That is, it is preferable to use a panel different from the solar cell panel 31 for the solar cell module arranged instead of the solar cell module 10B.

In the solar cell module 40 illustrated in FIG. 7, an angle θ _43c formed by one end surface 45c of the frame 43c that abuts the end surface 45e of the oblique frame 43e and the outer peripheral side surface 46c, and an angle formed by the end surface 45e and the outer peripheral side surface 46e. θ _43e is substantially the same. Further, the angle θ _43d formed by one end surface 45d of the frame 43d that abuts the end surface 45e of the oblique frame 43e and the outer peripheral side surface 46d is substantially the same as the angle θ _43e . In this case, the end faces 45c and 45e and the end faces 45d and 45e are in a state of being matched, and the hollow portions of the frames 43c and 43d are not exposed. Although the lengths of the frames 43c and 43d are substantially the same, the angles of the two end faces 45c and 45d are different from each other, so that the frames 43c and 43d cannot be shared.
