Japanese Patent Application Publication No. 2013-122126

By the way, when installing a solar cell module, connect the free end of the distribution cable, one end of which is fixed to the power generation panel, to a predetermined connection position (for example, the tip of the distribution cable connected to another power generation panel). There is a need to. The power distribution cable is connected to the back of the power generation panel (the surface facing the wall). Therefore, when the lower end of the power generation panel is rotatably attached to the wall as in the solar panel installation method of Patent Document 1, the lower end of the power generation panel is attached to the wall while the power generation panel is moving relative to the wall and the lower end of the power generation panel is attached to the wall. The free end of the power distribution cable moves freely in the installed state. Therefore, when connecting the free end of a power distribution cable to a predetermined connection position, it is necessary to search for the free end of the power distribution cable, and the free end of the power distribution cable does not match the surrounding configuration after being connected to a predetermined connection position. There is a risk of damage due to contact with other objects.

Furthermore, when attaching the power generation panel to a wall surface, it is necessary to arrange the power generation panel at a predetermined position. Here, it is conceivable that the worker grasps the left and right ends of the power generation panel described in Patent Document 1 with both hands, but the power generation panel, which is plate-shaped and has a certain amount of weight, is placed in a predetermined position by hand. It is difficult to perform the work stably.

An object of the present invention is to facilitate confirmation of the position of the free end of a power distribution cable when attaching a solar cell module to a wall surface, to suppress damage to the free end, and to make the work of moving power generation panels more efficient. An object of the present invention is to provide a solar cell module, a building, and a method for installing the solar cell module.

In order to solve the above problems, the present invention provides a solar cell module, which includes a panel body having a power generation element that receives sunlight and generates electricity, and a panel body provided at a lower part of the panel body, such that the upper end of the panel body is separated from a wall surface. The panel body can be rotatably attached to the wall surface between a separated position separated by a predetermined distance and a fixed position where the upper end of the panel body is close to the wall surface so that the panel body can be fixed to the wall surface. a power generation panel having a mounting portion; a first end portion fixed to a surface of the power generation panel facing the wall surface; and a second end portion connected to a predetermined connection point. and a linear member having both ends attached at horizontally spaced positions on a surface of the power generation panel facing the wall surface, and a linear member provided between the both ends of the linear member. A protection member that protects the power distribution cable, the protection member having a first holding portion that holds the second end of the power distribution cable.

The present invention also provides a solar cell module mounting method, which includes a step of preparing the solar cell module, a step of lifting the protection member and moving the solar cell module, and a step of mounting the lower part of the power generation panel on the wall surface. a step of movably attaching the linear member between the power generation panel and the protective member to the wall surface, and a second end of the power distribution cable held by the protective member. and fixing the upper part of the power generation panel to the wall surface.

In the solar cell module, the second end (free end) of the power distribution cable can be held by the first holding part of the protection member. Since this protection member is attached to the linear member, the second end of the power distribution cable can be restrained to the power generation panel by the linear member. Therefore, after the second end of the power distribution cable is held by the protection member, the operator can easily find the second end by pulling the linear member together. Furthermore, since the second end can be protected by the protective member, damage to the second end can be suppressed.

Moreover, since both ends of the linear member to which the protective member is attached are attached to the surface facing the wall surface of the power generation panel, the power generation panel can be easily opened by lifting the protective member (the middle part of the linear member). It can be moved.

In this way, the protective member used to move the power generation panel can also be used as a member to restrain the movement of the second end of the power distribution cable, so compared to the case where these are constructed from separate members. It is also possible to reduce costs.

In the solar cell module, the protection member may have a second holding part that holds a second end of a power distribution cable connected to another power generation panel.

In this aspect, when the second end of the power distribution cable is connected to the second end of the power distribution cable of another power generation panel, the second end of the power distribution cable of the other power generation panel is also connected to the protective member. can be retained. Therefore, the connection state between the power distribution cables of the two power generation panels can be maintained, and the possibility of unexpected disconnection can be reduced.

The solar cell module may further include a support member having a locking part to which the linear member is locked, and a fixed part connected to the locking part and fixable to the wall surface. good.

In this aspect, by attaching the support member to the wall surface via the fixed portion, movement of the power generation panel with respect to the wall surface can be restrained by the linear member. Therefore, it is possible to prevent the power generation panel from rotating toward the front with the lower part of the power generation panel attached to the wall surface, and the worker can release the power generation panel and perform other tasks.

In the solar cell module, the attachment position of the linear member on the surface of the power generation panel facing the wall surface may be above the center of the power generation panel in the height direction.

In this aspect, before attaching the upper part of the power generation panel to the wall surface, the lower part of the power generation panel is attached to the wall surface, and the linear member is placed at a position above the heightwise center of the power generation panel where it can be easily seen. can be placed. Therefore, the connection work of the power distribution cable can be performed more easily, and the installation work can be performed in a much shorter time.

In the solar cell module, the protective member includes a covering part that covers the entire circumference of the linear member, and an extending part that extends outside the covering part and is provided with the first holding part. Preferably, the extending portion is displaceable with respect to the covering portion between a posture in which the first holding portion is sandwiched between the first holding portion and the covering portion and a posture in which the first holding portion is released. .

In this aspect, by sandwiching the first holding portion between the extension portion and the covering portion, the second end portion of the power distribution cable can be more reliably protected.

The present invention also relates to a building, the building comprising: the wall surface; the solar cell module; A battery module, a locking part provided at a horizontally spaced position on the wall surface and to which the linear member is locked, and a fixed part connected to the locking part and fixed to the wall surface. and two support members having a support member, wherein the linear member supports the power generation panel in a direction in which the upper end of the power generation panel is further separated from the wall surface when the power generation panel is rotated to the separated position. The two support members have a length that allows rotation to be restricted, and the two support members are located at a position below the upper end of the power generation panel on the wall surface when the power generation panel is rotated to the fixed position, and at a position below the upper end of the power generation panel on the wall surface and is fixed at a position above the upper end of the power generation panel on the wall surface in a state in which the power generation panel is rotated to the separated position, and the protection member is provided in a portion of the linear member between the two support members. , providing buildings.

In this building, the rotation of the power generation panel can be restricted by the linear member while the power generation panel is rotated to the separated position. In this state, the linear member is stretched, and furthermore, a protective member is provided at a portion of the wall surface between two support members fixed at a position above the upper end of the power generation panel. Therefore, the protective member can be placed at an easily visible position above the power generation panel with the upper end of the power generation panel spaced apart from the wall surface.

On the other hand, the two support members are disposed below the upper end of the power generation panel on the wall surface when the power generation panel is rotated to the fixed position. Therefore, while the upper end of the power generation panel is fixed to the wall surface, the support member, the linear member, and even the protection member can be stored between the power generation panel and the wall surface.

According to the present invention, it is possible to easily confirm the position of the free end of a power distribution cable when installing a solar cell module on a wall surface, to suppress damage to the free end, and to make the work of moving the power generation panel more efficient. .

Both ends 41, 41 are fixed to. Moreover, the linear member 4 restricts the rotation of the power generation panel 3 in the direction in which the upper end of the power generation panel 3 is further separated from the wall surface 1 when the power generation panel 3 is in the separated position (the state shown by the solid line in FIGS. 1 to 3). It has the possible length.

Further, in this embodiment, both ends 41, 41 of the linear member 4 are attached to the left and right ends of the wall facing surface 30a of the panel body 30, respectively, so as to be approximately symmetrical with respect to the left and right center line of the power generation panel 3. Fixed.

The support member 6 allows the power generation panel 3 to rotate between the fixed position (the state shown by the dashed-dotted line in FIGS. 2 and 3) and the separated position (the state shown by the solid line in FIGS. 1 to 3) while separating the power generation panel 3. This is for regulating the rotation of the power generation panel 3 in the position. Further, the two support members 6 are provided on mutually opposing surfaces (flanges 9b) of the two rails 9. Here, since the power generation panel 3 is attached to the wall surface 1 so as to cover the mutually opposing surfaces of the rail 9 from the front, both support members 6 are covered from the front by the power generation panel 3 in the fixed position. In this embodiment, since the two support members 6 have the same configuration, one support member 6 will be explained and the explanation of the other support member 6 will be omitted.

Specifically, as shown in FIG. 7, in this embodiment, each support member 6 includes a support main body 61 formed of a metal plate, and a linear member 4 that is movable in the axial direction. It is provided with a locking portion 62 to be locked.

The support body portion 61 includes a rectangular holding portion 611 that holds the locking portion 62 and a fixed portion 612 provided at an end of the holding portion 611 and fixed to the rail 9.

In this embodiment, the locking portion 62 includes an annular portion 621 through which the linear member 4 is movably inserted, and an attached portion 622 attached to the holding portion 611.

In this embodiment, the annular portion 621 includes an opening 621a, through which the linear member 4 can be taken in and out of the annular portion 621. Note that the annular portion 621 is not limited to having an opening 621a, and may be, for example, not having an opening 621a.

The fixed portion 612 includes a screw insertion hole 612a into which a fixing screw 612b is inserted.

The two supporting members 6 are fixed to predetermined positions on the wall surface 1 via the rails 9 with fixing screws 612b.

Specifically, the two support members 6 are located at a position where the support members 6 are lower than the upper end of the power generation panel 3 on the wall surface 1 at the fixed position (the state shown by the dashed line in FIG. 3), and at the separated position (the state shown by the dashed line in FIG. , the state shown by the solid line in FIG. 3), the support member 6 is located above the upper end of the power generation panel 3 on the wall surface 1.

Further, the positions of the two support members 6 in the left-right direction are between the power generation panel 3 and the wall surface 1 when viewed from the front in the fixed position, that is, the left support member 6 is on the right side of the left end of the power generation panel 3. The right support member 6 is located to the left of the right end of the power generation panel 3. That is, the mutually opposing flanges 9b of the two rails 9 are arranged between the left end and the right end of the power generation panel 3, and the support members 6 are fixed to the flanges 9b of these rails 9, respectively.

For example, the two support members 6 can be arranged at positions substantially facing each of both ends 41, 41 of the linear member 4 in the fixed position of the power generation panel 3 (the state shown by the dashed line in FIG. 3).

In addition, as shown in FIG. 1, the linear member 4 passed through the annular portion 621 of the two supporting members 6 has no slack in the separated position of the power generation panel 3 (the state shown in FIGS. 1 and 3). I become nervous. Therefore, in this embodiment, at the separated position of the power generation panel 3, the linear member 4 restricts the rotation of the power generation panel 3 toward the front side.

The protection member 5 is provided in a portion of the linear member 4 between the two support members.

Next, a method for attaching the solar cell module 2 to the wall surface 1 will be explained.

First, the solar cell module 2 configured as described above is prepared.

Next, the protection member 5 is lifted by hand or using a lifting operation means such as the crane 200, and the solar cell module is moved.

At this time, as shown in FIG. 8, the protection member 5 is divided into two parts, with the first holding part 521 and the second holding part 522 being on the inside, based on the boundary between the covering part 51 and the extension part 52. Folded. Therefore, damage to the linear member 4 and the second ends 72, 172 of the power distribution cables 7, 170 can be prevented when the protection member 5 is suspended by hand or by a suspension operation means such as the crane 200.

As shown in FIG. 2, by moving the power generation panel 3 so that the attachment part 31a of the power generation panel 3 is placed on the support part 11a of the first attached part 11 from above, the lower part of the power generation panel 3 is Attach it so that it can rotate.

At this time, since the power generation panel 3 is moved by lifting the linear member 4 (protection member 5), the power generation panel 3 can be easily attached to the wall surface 1 while being positioned.

Then, the two supporting members 6 are fixed with fixing screws 612b, for example, at positions on the wall surface 1 (rail 9) substantially facing each of both ends 41, 41 of the linear member 4.

In addition, when the annular part 621 is provided with the opening 621a as in this embodiment, the two supporting members 6 may be fixed to the wall surface 1 before moving the solar cell module 2. good. On the other hand, when using the support member 6 without the opening 621a, it is necessary to attach one end of the linear member 4 to the linear member 4 with one end passed through the support member 6 in advance. Furthermore, if a member (for example, a carabiner, etc.) having a mechanism that can be opened and closed in order to insert and remove the linear member 4 is used as the support member 6, the timing for attaching the support member 6 can be freely selected.

By passing the linear member 4 through the annular portion 621 through the opening 621a, a portion of the linear member 4 between the power generation panel 3 and the protection member 5 is locked to the wall surface 1.

Then, holding of the protection member 5 is stopped. As a result, the upper end of the power generation panel 3 rotates toward the front (clockwise in FIG. 2). That is, a state in which the power generation panel 3 is rotated by a predetermined angle α (15° in this embodiment) with respect to the fixed position fixed to the wall surface 1 (the state shown by the dashed line in FIGS. 2 and 3), that is, Rotation of the power generation panel 3 is restricted at a separated position where the upper end of the panel body 30 is separated from the wall surface 1 by a predetermined distance. Specifically, the linear member 4 is brought into a tensioned state with no slack, and the rotation of the power generation panel 3 toward the front side is restricted.

When the linear member 4 is in a substantially tensioned state, the protective member 5 is disposed above the upper end of the power generation panel 3, as shown in FIG.

In this state, the second end 72 of the power distribution cable 7 is connected to the second end 172 of the power distribution cable 170 of another power generation panel.

Both ends 72 and 172 connected in this way are held by the first holding part 521 and the second holding part 522 of the protection member 5.

Note that the power generation panel 3 may be attached to the wall surface 1 with the second end 72 of the power distribution cable 7 removed from the first holding part 521 of the protection member 5 as described above. The power generation panel 3 may be attached to the wall surface 1 while the second end portion 72 of the cable 7 is held by the first holding portion 521 of the protection member 5.

At this time, since the protection member 5 is disposed above the power generation panel 3, the second ends 72, 172 can be easily held by the protection member 5.

Then, as shown in FIG. 4, by fixing the second clamping piece 12b of the second attached part 12 to the first clamping piece 12a with the bolt 12c, the power generation panel 3 is covered between the clamping pieces 12a and 12b. The power generation panel 3 is fixed to the wall surface 1 by being held by the holding portions 31b.

In this state, the upper end of the power generation panel 3 comes closest to the wall surface 1 (the fixed position shown by the dashed line in FIGS. 2 and 3).

At this fixed position, the power distribution cable 7, the wire member 4, the protection member 5, and the two support members 6 are arranged between the wall surface 1 and the power generation panel 3, and are not visible from the outside. hidden.

In addition, in this fixed position, the linear member 4 is loosened, and the protection member 5 hangs down below the support member 6, for example, as shown by the dashed line in FIG.

Thereafter, a plurality of solar cell modules 2 are attached to predetermined positions on the wall surface 1 in the same manner.

In the solar cell module 2, the second end (free end) 72 of the power distribution cable 7 can be held by the first holding part 521 of the protection member 5. Since the protective member 5 is attached to the linear member 4, the second end 72 of the power distribution cable 7 can be restrained to the power generation panel 3 by the linear member 4. Therefore, after the second end 72 of the power distribution cable 7 is held by the protection member 5, the operator can easily find the second end 72 by pulling the linear member 4 together. . Furthermore, since the second end portion 72 can be protected by the protective member 5, damage to the second end portion 72 can be suppressed.

Furthermore, since both ends of the linear member 4 to which the protection member 5 is attached are attached to the surfaces facing the power generation panel 3, the power generation panel 3 can be easily moved by lifting the protection member 5.

In this way, since the protective member 5 used to move the power generation panel 3 can also be used as a member to restrain the movement of the second end 72 of the power distribution cable 7, it is possible to configure these members with separate members. It is also possible to reduce costs compared to the case where

Since the protection member 5 has the second holding portion 522, the connection state between the power distribution cables of the two power generation panels can be maintained, and the possibility that the connection will be unexpectedly disconnected can be reduced.

In addition, in the said embodiment, although the extending part 52 which has the 1st holding part 521 and the 2nd holding part 522 was provided in the protection member 5, it is not limited to this form and can be changed as appropriate. For example, the extending portion 52 may include only the first holding portion 521.

Further, in the embodiment, the first holding part 521 is formed by the extending part 52 extending from the covering part 51 and the first holding piece 521a, but it is not limited to this form and may be modified as appropriate. can. For example, the first holding part may be configured of a binding band that can detachably hold the second end 72 of the power distribution cable 7, and the binding band may be removably or non-removably locked to the covering part 51. good.

Since the solar cell module 2 includes the support member 6, movement of the power generation panel 3 with respect to the wall surface 1 can be restrained by the linear member 4. Therefore, it is possible to prevent the power generation panel 3 from rotating toward the front with the lower part of the power generation panel 3 attached to the wall surface 1, and the worker can take his hands off the power generation panel 3 and perform other tasks. .

Furthermore, rotation of the power generation panel 3 can be restricted by the linear member 4 in a state where the upper end of the power generation panel 3 is separated from the wall surface 1 by a predetermined distance. In this state, the linear member 4 is stretched, and a protective member 5 is provided between the two support members 6 fixed at a position above the upper end of the power generation panel 3 on the wall surface 1. There is. Therefore, the protection member 5 can be placed at an easily visible position above the power generation panel 3 with the upper end of the power generation panel 3 spaced apart from the wall surface 1.

On the other hand, the two support members 6 are arranged at a position below the upper end of the power generation panel 3 on the wall surface 1 in a state where the upper end of the power generation panel 3 is closest to the wall surface 1 . Therefore, with the upper end of the power generation panel 3 fixed to the wall surface 1, the support member 6, the linear member 4, and further the protection member 5 can be accommodated between the power generation panel 3 and the wall surface 1.

Note that in the embodiment described above, the rotation of the power generation panel 3 toward the front side is restricted by the tension of the linear member 4, but the present invention is not limited to this embodiment. For example, the attachment portion 31a of the power generation panel 3 may come into contact with a rotation restriction portion provided on the first attached portion 11 to restrict the rotation of the power generation panel 3 toward the front side, or in addition to this, the rotation of the power generation panel 3 toward the front may be restricted. As in the embodiment described above, the rotation of the power generation panel 3 toward the front side may be restricted by the tension of the linear member 4.

In the solar cell module 2, the attachment position of the linear member 4 on the surface of the power generation panel 3 facing the wall surface 1 is set above the center of the power generation panel 3 in the height direction. Therefore, before attaching the upper part of the power generation panel 3 to the wall surface 1, with the lower attachment part of the power generation panel 3 attached to the wall surface 1, the linear member 4 is placed above the center of the power generation panel 3 in the height direction. It can be placed in a position where it can be easily seen.

In the solar cell module 2, the protective member 5 has a covering part 51 and an extending part 52, and can take a position in which the first holding part 521 is sandwiched between the covering part 51 and the covering part 51. By sandwiching the first holding portion 521 between the extending portion 52 and the covering portion 51, the second end portion 72 of the power distribution cable 7 can be protected more reliably.

Further, when the solar cell module 2 has a ground wire with a first end fixed to the power generation panel 3, the second end on the tip side of the ground wire may be held in the protective member 5. .

Although the power distribution cable 170 of another power generation panel is illustrated as the "predetermined connection point," it is not limited thereto. For example, a power distribution cable may be connected to a ground point provided on a wall surface as a "predetermined connection point."
