The solar cell system 100 includes a plurality of solar cell modules 4 and a solar cell module fixing device 101 in which the plurality of solar cell modules 4 are laid out side by side on the roof surface 1 of the house 110. The roof surface 1 of the house 110 is an inclined surface that slopes downward from the ridge 1a to the eaves 1b. Further, the roof surface 1 is a metal horizontal roof.

The solar cell module 4 is configured by mounting an aluminum frame 402 on the outer periphery of the solar cell panel 401, which is a photovoltaic power generation function body formed in a square flat plate shape. In the solar cell system 100, a plurality of solar cell modules 4 are laid out side by side in an inclined direction of the roof surface 1 and a direction perpendicular to the inclined direction. The size of the solar cell modules 4 and the number of the solar cell modules 4 arranged vertically and horizontally can be appropriately changed according to the size of the roof surface 1. As the solar cell used for the solar cell panel 401, either a single crystal silicon solar cell, a polycrystalline silicon solar cell, or the like may be used. Further, the solar cell panel 401 may be a thin-film solar cell formed on a transparent surface protection substrate. The solar cell panel 401 may have any structure as long as it has a structure formed in a rectangular flat plate form.

The solar cell module fixing device 101 includes a roof mounting bracket 2, a vertical rail 3, a module fixing bracket 5, and a rope mounting bracket 6.

The roof mounting brackets 2 are arranged side by side from the ridge 1a on the roof surface 1 toward the eaves 1b. In the following description, the direction from the ridge 1a on the roof surface 1 toward the eaves 1b is simply referred to as an inclination direction. The roof mounting brackets 2 are also arranged side by side in the direction perpendicular to the inclination direction.

FIG. 4 is an enlarged view of a portion A shown in FIG. The roof mounting bracket 2 is formed with a screw hole 201 through which a wood screw 10 is passed through a bottom surface portion 202 that is in contact with the roof surface 1. The roof mounting bracket 2 is fixed to the roof surface 1 by a wood screw 10. The roof mounting bracket 2 has a top surface portion 203 facing the bottom surface portion 202. The upper surface portion 203 has a vertical rail support surface 204 that supports the vertical rail 3. The upper surface portion 203 has a guide rail 205 for passing the bolt 11 from the side surface. The shaft portion of the bolt 11 passed through the guide rail 205 projects from the vertical rail support surface 204 toward the solar cell module 4.

The vertical rail 3 extends along the inclined direction, and connects a plurality of roof mounting brackets 2 arranged side by side along the inclined direction. FIG. 5 is a perspective view of the vertical crosspiece 3 according to the first embodiment. The vertical rail 3 has a bottom surface portion 301 mounted on the vertical rail support surface 204. An elongated hole 302 for passing the bolt 11 is formed in the bottom surface portion 301. The vertical rail 3 is fixed to the vertical rail support surface 204 by using bolts 11 and nuts 12 passed through the elongated holes 302.

When viewed along the inclined direction, the vertical rail 3 is provided with a side surface portion 305 extending from the side of the bottom surface portion 301 toward the solar cell module 4. A hole 306 penetrating the side surface portion 305 is formed at an end portion of the side surface portion 305 on the ridge 1a side. The vertical rail 3 has a top surface portion 303 facing the bottom surface portion 301. A slit 303a extending in the inclined direction is formed on the upper surface portion 303. A guide rail 304 facing the upper surface portion 303 is formed on the bottom surface portion 301 side of the upper surface portion 303. A fastener 13 integrated with a nut is passed between the upper surface portion 303 and the guide rail 304.

The solar cell module 4 is mounted on the upper surface portion 303 of the vertical rail 3. That is, in the first embodiment, the vertical rail 3 serves as a support metal fitting for supporting the solar cell module 4. Further, the upper surface portion 303 of the vertical rail 3 serves as a support surface for supporting the solar cell module 4. When the roof surface 1 is a metal horizontal roof or a tiled roof, the vertical rail 3 is often used to fix the solar cell module 4.

The module fixing bracket 5 engages with the frame 402 of the solar cell module 4 by being fixed to the vertical rail 3 by the fastener 13 and the bolt 14 provided on the vertical rail 3. As a result, the solar cell module 4 is fixed to the vertical rail 3. There are various types of module fixing brackets, and the module fixing brackets used in the solar cell system 100 are not limited to those illustrated in FIG. 2 and the like.

The roof mounting bracket 2, the vertical rail 3, and the module fixing bracket 5 described above are preferably made of a material that is light, easy to process, and does not rust, and is made of, for example, aluminum.

FIG. 6 is a perspective view of the rope mounting bracket 6 according to the first embodiment. The rope mounting bracket 6 which is a rope mounting portion is a plate member in the shape of a flat plate. The rope mounting bracket 6 is formed with a hole 601 for passing the bolt 11. The rope mounting bracket 6 is formed with at least one hole 701 through which the rope 8 passes. Then, the rope mounting bracket 6 is fixed to the vertical rail 3 by the bolts 11 and nuts 12 passed through the holes 306 provided on the ridge side of the vertical rail 3 and the holes 701 of the rope mounting bracket 6. The rope mounting bracket 6 is preferably made of an aluminum plate from the viewpoint of strength and weather resistance.

It is arbitrary which vertical rail 3 the rope mounting bracket 6 is attached to. For example, in view of the purpose of inspecting the solar cell module 4 or the solar cell module fixing device 101, the solar cell module 4 or the solar cell module fixing device 101 may be provided at two locations at both ends or one central location along the direction perpendicular to the inclination direction. Alternatively, it may be provided at two or three places where the end portion along the direction perpendicular to the inclination direction and the center portion are combined.

The inspection method of the solar cell module 4 or the solar cell module fixing device 101 in the solar cell system 100 configured as described above will be described with reference to FIGS. 1 and 7. Note that FIG. 7 is a diagram showing a state in which the rope 8 is fixed to the rope mounting bracket 6 in the first embodiment. Further, FIG. 1 shows an example in which rope mounting brackets 6 are provided at both ends along a direction perpendicular to the inclination direction of the roof surface 1.

First, as shown in FIG. 7, the rope 8 which is the main rope is fixed to the rope mounting bracket 6. The rope 8 is passed through the hole 701 of the rope mounting bracket 6 and the rope fixing bracket 14 attached to the tip of the rope 8 is used to prevent the rope 8 from falling off. The rope fixing metal fitting 14 exemplifies a special metal fitting called a carabiner, but the present invention is not limited to this, and any other shape may be used as long as the rope 8 can be fixed. For example, the rope 8 may be simply tied to the rope mounting bracket 6. By fixing both ends of the rope 8 to the rope mounting bracket 6, the rope 8 is laid over the portion of the solar cell system 100 on the ridge 1a side in the direction perpendicular to the inclination direction as shown in FIG.

Next, the rope 9 which is a child rope is attached to the middle portion of the rope 8 by the expansion / contraction adjuster. By attaching a safety belt to the rope 8 which is the main rope or the rope 9 which is the child rope attached to the rope mounting bracket 6 by using the expansion / contraction adjuster in this way, the operator is prevented from falling on the roof surface 1. In this state, the solar cell module 4 or the solar cell module fixing device 101 can be inspected.

Further, by moving the safety belt or the expansion / contraction adjuster attached to the rope 8, it can be easily moved to any place of the solar cell system 100, and the inspection range is not limited. Further, since the place where the rope 8 and the rope 9 are attached is limited to the roof surface 1, monitoring on the ground is unnecessary as in the case of fixing the main rope to the ground, and labor costs can be reduced. As the expansion / contraction regulator and the safety belt, those specified in JIS T8165 "Safety belt" can be used.

Embodiment 2.
FIG. 8 is an exploded perspective view of the solar cell system according to the second embodiment of the present invention. FIG. 9 is a side view of the solar cell system according to the second embodiment. The same configurations as those in the above-described embodiment are designated by the same reference numerals and detailed description thereof will be omitted. In the second embodiment, the configuration of the solar cell system 100 excluding the rope mounting bracket 7 is the same as that of the first embodiment. In the second embodiment, the hole 306 is formed in the bottom surface 301 on the ridge 1a side of the vertical rail 3.

FIG. 10 is a perspective view of the rope mounting bracket 7 according to the second embodiment. The rope mounting bracket 7 has a bottom surface fixing portion 7a fixed to the bottom surface portion 301 of the vertical rail 3, and an extending portion 7b extending from the bottom surface fixing portion 7a and extending in a direction away from the roof surface 1. It has an L-shape as a whole. A hole 701 through which the rope 8 is passed is formed in the extending portion 7b. A position where the distance between the hole 701 and the upper surface portion 303 of the vertical rail 3 is longer than the distance between the light receiving surface 4a of the solar cell module 4 and the roof surface 1 in a state where the rope mounting bracket 7 is fixed to the vertical rail 3. A hole 701 is formed in the hole 701. As a result, the hole 701 of the rope mounting bracket 7 projects upward from the light receiving surface 4a of the solar cell module 4.

The position where the rope mounting bracket 7 is provided, the mounting of the rope 8 on the rope mounting bracket 7, and the inspection method of the solar cell system 100 are the same as those described in the first embodiment. In the second embodiment, since the hole 701 of the rope mounting bracket 7 projects upward from the light receiving surface 4a of the solar cell module 4, the rope 8 fixed to the rope mounting bracket 7 interferes with the solar cell system 100. It becomes difficult to do. Therefore, the safety belt or the expansion / contraction adjuster attached to the rope 8 can be easily moved, and the operator can be easily moved. Further, it is possible to prevent the solar cell module 4 from being damaged by the rope 8.

Embodiment 3.
FIG. 11 is an exploded perspective view of the solar cell system according to the third embodiment of the present invention. FIG. 12 is a side view of the solar cell system according to the third embodiment. FIG. 13 is a perspective view of the vertical crosspiece according to the third embodiment. The same configurations as those in the above embodiment are designated by the same reference numerals and detailed description thereof will be omitted.

In the third embodiment, as shown in FIG. 13, a hole 310 for passing the rope 8 is formed in the side surface portion 305 of the vertical rail 3. That is, in the third embodiment, the vertical rail 3 in which the hole 310 is formed serves as the rope attachment portion.

This makes it possible to reduce the number of parts as compared with the configurations described in the first and second embodiments. Further, usually, the length of the vertical rail 3 along the inclination direction is the length in the flow direction of the solar cell module 4. That is, the length of the vertical crosspiece 3 along the inclination direction is (the length of the solar cell modules along the inclination direction × the number of the solar cell modules arranged along the inclination direction) + (the length between the solar cell modules). X (number of solar cell modules arranged along the inclination direction-1)) + a. Here, a is a dimension required for attaching the module fixing bracket or the eaves cover to the end portion on the building 1a side and the end portion on the eaves 1b side, and is an arbitrarily determined dimension.

The length of the vertical rail 3 of the third embodiment is extended further toward the building 1a than the normal vertical rail 3 described above, so that the end of the vertical rail 3 on the building 1a side can be extended to the building 1a of the solar cell module 4. It can be projected further toward the ridge 1a side than the side end. By forming the hole 310 in the protruding portion, the solar cell module 4 is less likely to get in the way when fixing or removing the rope 8, and workability is improved. The method of attaching the rope 8 to the hole 310 and the method of inspecting the solar cell system 100 are the same as those described in the first embodiment.

Embodiment 4.
FIG. 14 is a side view of the solar cell system according to the fourth embodiment of the present invention. FIG. 15 is an enlarged perspective view of the ridge-side portion of the vertical rail according to the fourth embodiment. The same configurations as those in the above embodiment are designated by the same reference numerals and detailed description thereof will be omitted.

In the fourth embodiment, the rope mounting bracket 70 is fixed to the fastener 13 passed through the guide rail 304 of the vertical rail 3. The fastener 13 is a screw hole portion in which a screw hole 13a is formed. The rope mounting bracket 70 has a shaft portion 70b screwed into the screw hole 13a and a hole portion 70a formed integrally with the shaft portion 70b. A hole 701 through which the rope 8 is passed is formed in the hole 70a. The rope mounting bracket 70 is, for example, an eyebolt. Further, a washer 702 is sandwiched between the rope mounting bracket 70 and the fastener 13. By making the outer diameter of the washer 702 larger than the slit 303a of the vertical rail 3, the rope mounting bracket 70 can be fixed by sandwiching the upper surface portion 303 of the vertical rail 3 between the washer 702 and the fastener 13.

As a result, it is possible to reduce the number of holes formed in the vertical crosspiece 3 as compared with the configurations illustrated in the first to third embodiments. Therefore, the strength of the vertical rail 3 can be improved. Since it is necessary to additionally provide the fastener 13 for fixing the rope mounting bracket 70 in addition to the fastener 13 for fixing the module fixing bracket 5, the vertical rail 3 is on the building 1a side of the solar cell module 4. It is necessary to extend it further toward the building 1a side than the end of the building. The position where the rope mounting bracket 70 is provided, the mounting of the rope 8 on the rope mounting bracket 70, and the inspection method of the solar cell system 100 are the same as those described in the first embodiment.

In the fifth embodiment, the module fixing bracket 501, which is a holding bracket for fixing the solar cell module 4 provided on the side of the building 1a, is fixed by a rope mounting bracket 70 instead of a bolt. As a result, the number of fasteners 13 can be reduced as compared with the configuration of the fourth embodiment. Also, washers are not required. Unlike the module fixing bracket 5, the module fixing bracket 501 is provided with a portion engaged with the solar cell module only on the eaves 1b side. This facilitates the attachment of the rope 8 to the rope attachment bracket 70. Further, the position where the rope mounting bracket 70 is provided, the mounting of the rope 8 to the rope mounting bracket 70, and the inspection method of the solar cell system 100 are the same as those described in the first embodiment.
