[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A module support bracket, a photovoltaic power generation system, and a module installation method according to an embodiment of the present invention will now be described with reference to the drawings. First, a first embodiment will be described.

[0013] FIG. 1 is a diagram showing a photovoltaic power generation facility according to the first embodiment.

[0014] The solar power generation facility 1 of this embodiment is an array structure facility in which two solar cell modules 10 are arranged next to each other. The solar cell module 10 is a power generation module having a rectangular flat module body 11 and a metal frame 12 that holds the outer periphery of the module body 11. The solar power generation facility 1 is installed on a folded-plate roof A11, which is a type of inclined roof. The two solar cell modules 10 are installed on the folded-plate roof A11 using six module support brackets 100 and six foundation members 150.

[0015] In this solar power generation facility 1, two solar cell modules 10 each having a rectangular shape in plan view are arranged along the inclination direction D11 so that the short sides of each solar cell module 10 are aligned with the inclination direction D11 of the folded-plate roof A11 and the long sides are adjacent to each other. These two solar cell modules 10 are supported on the folded-plate roof A11 by the module support bracket 100 via the foundation member 150. One long side of the solar cell module 10 is supported by two module support brackets 100 and the foundation member 150. Specifically, in the inclination direction D11, one long side of each of the eaves side end and the ridge side end is supported by two module support brackets 100 and the foundation member 150. In addition, two adjacent long sides are supported together by two module support brackets 100 and the foundation member 150.

[0016] Fig. 2 is an enlarged view of the module support fitting and the base member shown in Fig. 1, showing an area AR11 in Fig. 1. Also, Fig. 3 is a plan view of the module support fitting and the base member shown in Fig. 1, seen from the direction of arrow V11 in Fig. 2.

[0017] In the solar power generation facility 1 of this embodiment, a base member 150 is fixed to a trapezoidal apex A111 of a folded-plate roof A11 that is folded so that a cross section perpendicular to the inclination direction D11 is approximately trapezoidal, and a module support bracket 100 is attached to this base member 150. The base member 150 is a rail member formed into a rectangular tube shape with a groove slit 152 in a rail groove 151 opened on one side by sheet metal processing in which a metal plate is folded. The base member 150 is adhesively fixed to the trapezoidal apex A111 of the folded-plate roof A11 via an adhesive sheet 153 so that the rail groove 151 extends along the inclination direction D11 of the folded-plate roof A11. The module support bracket 100 is attached so as to fit into the rail groove 151 of this base member 150.

[0018] The module support bracket 100 includes an installation bracket 110, a frame bracket 120, and a fixing member 130. The installation bracket 110 is a processed sheet metal bracket that is attached to the trapezoidal top A111 of the folded-plate roof A11, which is the installation location, via the above-mentioned foundation member 150. The frame bracket 120 is a processed sheet metal bracket that is arranged with an insertion gap T11 for inserting the metal frame 12 of the solar cell module 10 so as to sandwich the metal frame 12 between the installation bracket 110 and the frame bracket 120. The fixing member 130 is a member that fixes the frame bracket 120 to the installation bracket 110, and includes a fixing bolt 131 and a fastening nut 132.

[0019] Here, before further description of the module support bracket 100 and the foundation member 150, the configuration of the metal frame 12 of the solar cell module 10 will be described. The metal frame 12 is a rectangular frame-like frame that holds the outer periphery of the module body 11, which is a rectangular flat plate. The metal frame 12 has a connecting portion 12a, a side plate portion 12b, and a back plate portion 12c. The connecting portion 12a is a portion that is connected to the outer periphery of the module body 11. The side plate portion 12b is a portion that extends perpendicularly from the connecting portion 12a to the back surface 11b of the module body 11 opposite the light receiving surface 11a in the direction intersecting the module body 11. The back plate portion 12c is a portion that extends perpendicularly from the edge of the side plate portion 12b opposite to the connecting portion 12a along the back surface 11b of the module body 11 toward the center of the module body 11.

[0020] The metal frame 12 of such a solar cell module 10 is supported by a module support bracket 100 attached to a foundation member 150 on the folded-plate roof A11.

[0021] Fig. 4 is a three-view drawing showing the module support metal fitting and the base member shown in Fig. 1 to Fig. 3. Also, Fig. 5 is a three-view drawing showing the installation side metal fitting shown in Fig. 4, and Fig. 6 is a three-view drawing showing the frame side metal fitting shown in Fig. 4.

[0022] As described above, the module support bracket 100 attached to the foundation member 150 includes the installation side bracket 110, the frame side bracket 120, and the fixing member 130. The installation side bracket 110 is a member attached to the foundation member 150, and includes a back plate mounting portion 111 and a contact protrusion 112.

[0023] The back plate mounting portion 111 is inserted into the rail groove 151 of the base member 150 through one end opening 151a of the rail groove 151. A part of the rail groove 151 is exposed from the groove slit 152 in the depth direction of the rail groove 151, and the back plate portion 12c of the metal frame 12 is placed on the exposed part. The back plate mounting portion 111 has a central protrusion portion 111a, a pair of side ends 111b, and a pair of abutting ends 111c. The central protrusion portion 111a is a protrusion formed by a rectangular band-shaped portion and side wall portions folded down at right angles from a pair of long sides of the central protrusion portion 111a. The pair of side ends 111b are portions extending to the left and right from the respective lower end edges of the pair of side wall portions of the central protrusion portion 111a, and are supported from the groove bottom 151b side by a support protrusion 154 described later inside the rail groove 151 of the base member 150. The pair of abutment ends 111c are formed by folding a central portion of a predetermined length at the edge of each of the pair of side ends 111b at a right angle, and abut against a stopper protrusion 155 described below inside the rail groove 151 of the base member 150. In addition, both longitudinal ends of the central protrusion portion 111a are provided with abutment protrusions 112 described below and contact surfaces 111d whose tops bulge out like flat plateaus and contact the back plate portion 12c of the metal frame 12. The back plate portion 12c is placed on the contact surfaces 111d of the installation metal fitting 110 attached to the base member 150 and on the upper surface portions of the base member 150 located on both sides of the contact surfaces in the width direction.

[0024] The abutment protrusions 112 are portions that protrude from the back plate mounting portion 111 so as to abut against the inner edge 12c-1 of the back plate 12c opposite the side plate 12b as shown in Figures 2 and 3 when the back plate 12c is mounted as described above. In this embodiment, a pair of abutment protrusions 112 are formed at both longitudinal ends of the central protrusion portion 111a of the mounting metal fitting 110, bulging out in a plateau shape together with the contact surface portion 111d. Each abutment protrusion 112 is formed so as to be higher than the contact surface portion 111d, and is configured so as to abut against the inner edge 12c-1 of the back plate 12c mounted on the contact surface portion 111d.

[0025] The frame side metal fitting 120, which constitutes the module support metal fitting 100 together with the installation side metal fitting 110 described above, includes a clamping portion 121 and a restricting protrusion 122. The clamping portion 121 is a portion that clamps the metal frame 12 between the clamping portion 121 and the back plate mounting portion 111. The restricting protrusion 122 protrudes from the clamping portion 121 toward the back plate mounting portion 111 with a protrusion length L11 corresponding to the insertion gap T11 described above, and is a portion that restricts the gap between the clamping portion 121 and the back plate mounting portion 111 to the insertion gap T11. Furthermore, as shown in FIG. 3, the restricting protrusion 122 clamps the metal frame 12 between the clamping portion 121 and the abutting protrusion 112 of the installation side metal fitting 110. The restricting protrusion 122 is formed in an L-shape in cross section perpendicular to the protruding direction D12 from the clamping portion 121, and a pair of restricting protrusions 122 are formed so as to be line-symmetrical about the center of the clamping portion 121 in a plan view.

[0026] The frame side fitting 120 is a processed sheet metal part formed by bending the clamping portion 121 and the restricting protrusions 122 integrally. The clamping portion 121 is formed in a substantially rectangular plate shape, and is folded down from a pair of opposing side edges in the protruding direction D12, and is further folded at a substantially right angle toward the center of the clamping portion 121 at a crease along the protruding direction D12 to form a pair of restricting protrusions 122 with an L-shaped cross section. Also, the clamping portion 121 is formed at one end with a visor portion 123 that is folded up so as to move away from the back plate mounting portion 111.

[0027] As described above, the fixing member 130 includes the fixing bolt 131 and the fastening nut 132. The fixing bolt 131 is arranged so that the bolt head 131a is in sliding contact with the back surface of the back plate mounting portion 111 of the installation metal fitting 110, the back surface being opposite the mounting side of the back plate portion 12c. The fixing bolt 131 is erected on the back plate mounting portion 111 in a rotationally prevented state so that the bolt portion 131b passes through the back plate mounting portion 111 and the clamping portion 121 and avoids the insertion area of ​​the metal frame 12 into the insertion gap T11.

[0028] The clamping portion 121 of the frame side metal fitting 120 has a through hole 124 for the bolt portion 131b formed in the approximate center. On the other hand, the back plate mounting portion 111 of the installation side metal fitting 110 has a through hole 111e formed in the approximate center of the central protrusion portion 111a through which the bolt portion 131b passes. Furthermore, this through hole 111e is provided with anti-rotation protrusions 111f protruding inward at four circumferential positions on the inside of the through hole 111e so that the inserted bolt portion 131b is prevented from rotating. These four anti-rotation protrusions 111f are formed by punching after the bolt portion 131b is inserted. Note that the anti-rotation protrusion provided in the through hole of the bolt portion only needs to be provided at at least one position in the circumferential direction, and the number of positions is not limited to four. That is, the number of anti-rotation protrusions provided may be an appropriate number, such as one to three positions, five or more positions, unlike the present embodiment.

[0029] In this embodiment, the fixing bolt 131 has a bolt head 131a having a hexagonal columnar shape. A head anti-rotation protrusion 111g is provided on the back surface of the back plate mounting portion 111, which protrudes so as to abut against the side surface of the bolt head 131a and prevents the bolt head 131a from rotating. Unlike the above-mentioned four anti-rotation protrusions 111f, this head anti-rotation protrusion 111g is machined in advance together with the through hole 111e and the like before the fixing bolt 131 is attached. In addition, the bolt head is not limited to a hexagonal columnar shape, and the shape may be other polygonal columnar shapes such as a square columnar shape or an octagonal columnar shape, unlike this embodiment. As for the head anti-rotation protrusion, as long as it abuts against the side surface of the polygonal columnar shape to prevent the bolt head from rotating, the number of the head anti-rotation protrusions can be set appropriately, such as one, three or more.

[0030] Furthermore, the contact surfaces 111d at both ends of the back plate mounting portion 111 are provided with pressing protrusions 111h that protrude so as to push up the back plate portion 12c mounted on the back plate mounting portion 111 and press the metal frame 12 against the clamping portion 121 of the frame side metal fitting 120. In this embodiment, the pressing protrusions 111h are formed as peripheral walls of the edges of the through holes opened by burring processing from the back surface side.

[0031] Then, the installation side metal fitting 110 and the frame side metal fitting 120 are attached to the base member 150 as follows, and fixed with the fixing members 130, thereby forming the module support metal fitting 100.

[0032] FIG. 7 is a schematic diagram showing how the installation metal fitting and the frame metal fitting are attached to a base member and fixed with fixing members to form a module support metal fitting.

[0033] When the module support fitting 100 is constructed, first, the back plate mounting portion 111 of the installation side fitting 110 is inserted and fitted into the rail groove 151 from one end opening 151a of the base member 150, which is a rail member, in the insertion direction D13 shown by the arrow in the figure. At this time, three support protrusions 154 and one stopper protrusion 155 are provided on each of a pair of opposing inner surfaces of the rail groove 151. The three support protrusions 154 are formed by protruding inward and arranged in three in the insertion direction D13 as shown in FIG. 4. These three support protrusions 154 support a pair of side ends 111b of the back plate mounting portion 111 in a shelf-like manner from the groove bottom 151b side so as to restrict the movement of the back plate mounting portion 111 inserted and fitted from one end opening 151a toward the groove bottom 151b side. At this support position, the contact protrusion 112 and the contact surface portion 111d are in a state of being sunk inside the rail groove 151. One stopper protrusion 155 is formed to protrude inward as shown in Fig. 4 at a position lower than the support protrusion 154 in the inclination direction D11 when the base member 150 is fixed on the folded-plate roof A11 which is a sloping roof. This stopper protrusion 155 abuts against a pair of contact ends 111c of the back plate mounting portion 111 from the lower side so as to restrict the sliding movement of the back plate mounting portion 111 to the lower side in the inclination direction D11.

[0034] When the back plate mounting portion 111 is inserted and fitted into the rail groove 151 in this manner, the frame side metal fitting 120 is then attached so that the bolt portion 131b of the fixing bolt 131 protruding from the groove slit 152 passes through the through hole 124 (see FIG. 6) of the clamping portion 121. Thereafter, the fastening nut 132 is screwed onto the bolt portion 131b to fasten and fix the frame side metal fitting 120 to the installation side metal fitting 110. At this time, the tip of the regulating projection 122 protruding from the clamping portion 121 abuts against the upper surfaces of the upper walls 156 on both sides of the groove slit 152 of the foundation member 150, which is the abutment object, thereby regulating the gap between the clamping portion 121 and the back plate mounting portion 111 to the above-mentioned insertion gap T11. At this time, the back plate mounting portion 111 is pulled up by screwing the fastening nut 132 until the upper edges 111c-1 of the pair of abutment ends 111c abut against the rear surface of the upper wall 156 of the base member 150. When the upper edges 111c-1 of the abutment ends 111c abut against the rear surface of the upper wall 156, the abutment protrusions 112 and the contact surface portion 111d protrude from the groove slits 152, and become able to abut against the back plate portion 12c of the metal frame 12 of the solar cell module 10 and its inner edge 12c-1.

[0035] Here, in this embodiment, in order to prevent the frame side metal fitting 120 from rotating around the bolt shaft 131c of the fixing bolt 131 when fastening with the fastening nut 132, a rotation prevention jig, which will be described below, is used.

[0036] FIG. 8 is a diagram showing an anti-rotation jig that prevents the frame side metal fitting from rotating when fastened by the fastening nut.

[0037] 8, the anti-rotation jig 140 is a jig member that is pressed against a pair of restricting protrusions 122 on the frame side metal fitting 120 when the fastening nut 132 is fastened, thereby preventing rotation of the frame side metal fitting 120. This anti-rotation jig 140 is a processed sheet metal member that is bent into a C-shaped cross section, and is placed over the base member 150 so as to be pressed against the pair of restricting protrusions 122. The fastening nut 132 is fastened in this state, but the anti-rotation jig 140 is formed with an interference-preventing through hole 141 so as not to interfere with the abutment protrusions 112 and contact surface portion 111d that protrude from the groove slit 152 of the rail groove 151 when pulled up during fastening.

[0038] Next, a module installation method using the module support bracket 100 of this embodiment will be described.

[0039] Fig. 9 is a schematic diagram showing steps S111 to S113 in a module installation method for installing the solar power generation facility shown in Fig. 1 using the module support brackets shown in Fig. 1 to Fig. 8. Fig. 10 is a schematic diagram showing steps S114 to S116 in the module installation method. Note that Fig. 9 and Fig. 10 omit illustration of the folded-plate roof A11, which is the installation location.

[0040] In step S111 of the module construction method, the module support fittings 100 are attached to each of the two foundation members 150 fixed to the lowest eaves side of the six points on the folded plate roof A11 shown in FIG. 1. In this attachment, first, the back plate mounting portion 111 of the installation side fitting 110 of each module support fitting 100 is inserted and fitted in the rail groove 151 of each foundation member 150 in the insertion direction D13. This insertion and fitting is performed until the back plate mounting portion 111 is supported by the support protrusion 154 and abuts against the stopper protrusion 155. After that, the bolt portion 131b of the fixing bolt 131 of the fixing member 130 penetrates the clamping portion 121, and the frame side fitting 120 is attached in the attachment direction D14 so that the regulating protrusion 122 abuts against the upper wall 156 of the foundation member 150. Furthermore, the fastening nut 132 is lightly screwed into the bolt portion 131b in a state before torque tightening.

[0041] In the next step S112, the fastening nuts 132 of each module support fitting 100 are torque-tightened in sequence, with the anti-rotation jig 140 placed over the foundation member 150 so that it abuts against the restricting protrusions 122. The abutment of this anti-rotation jig 140 stops the rotation of the frame-side fitting 120 during torque tightening, and the frame-side fitting 120 is fastened and fixed to the installation-side fitting 110. At this time, the module support fitting 100 is attached to the adjacent foundation member 150 on the ridge side.

[0042] Steps S111 and S112 up to this point constitute a first fitting installation step as follows. First, as shown in Fig. 1, the module installation method in this embodiment is a module installation method in which the solar cell module 10 is installed on the folded-plate roof A11 using two pairs of module support fittings 100 for each solar cell module 10. Then, it is a step of installing the first fitting of each pair of module support fittings 100 at the first installation position on the eaves side of the two pairs of fitting installation positions that sandwich the solar cell module 10. Also, in this step, a rotation-stopping jig 140 is used to stop the rotation of the frame-side fitting 120, and the module support fitting 100 is installed in a completed state in which the frame-side fitting 120 is fixed to the installation-side fitting 110.

[0043] Step S113, which follows the first metal fitting installation steps of steps S111 and S112, is a module placement step in which one of the two solar cell modules 10 on the eaves side is placed. In this step S113, the metal frame 12 is inserted into the insertion gap T11 of the module support metal fitting 100, which is the first metal fitting, so that the inner edge 12c-1 abuts against the abutment protrusion 112, and the solar cell module 10 is placed. Also, at this time, the ridge side end of the solar cell module 10 is placed on the foundation member 150 on the ridge side to which the module support metal fitting 100 is not attached. To explain the work of this step S113 in more detail, the worker first slightly lifts the ridge side end to hold the solar cell module 10 at an angle. Then, while maintaining the angle, the worker inserts the eaves side of the metal frame 12 into the insertion gap T11 until it abuts against the restricting protrusion 122. By such oblique insertion, the eaves side of the metal frame 12 is inserted into the insertion gap T11 so as not to interfere with the pressing protrusions 111h and the abutment protrusions 112 of the installation-side metal fitting 110. After such oblique insertion, the worker lowers the ridge-side end of the solar cell module 10 that was being held up onto the ridge-side foundation member 150. By this ridge-side descent, the inner edge 12c-1 on the ridge side of the metal frame 12 abuts against the abutment protrusions 112 and is unable to come out even if it is pulled toward the ridge side, and the ridge side of the metal frame 12 is pushed upward by the pressing protrusions 111h and pressed against the clamping portion 121 of the frame-side metal fitting 120.

[0044] Following the module placement process of step S113, steps S114 and S115 are performed to perform a second fitting installation process of installing the module support fitting 100 on the foundation member 150 on the ridge side. First, in step S114, the installation side fitting 110 is attached to each of the two foundation members 150 on the ridge side so as to be adjacent to the ridge side of the metal frame 12 of the solar cell module 10. The installation side fitting 110 is attached by inserting and fitting the back plate placement portion 111 into the rail groove 151 of the foundation member 150 in the insertion direction D13. In step S115, the frame side fitting 120 is attached in the attachment direction D14 so that the clamping portion 121 is penetrated by the bolt portion 131b of the fixing bolt 131 and the restricting protrusion 122 abuts against the foundation member 150. Thereafter, the fastening nut 132 is screwed in, and the fastening nut 132 is torque-tightened in a state in which the frame side fitting 120 is prevented from rotating by the anti-rotation jig 140. This torque tightening fixes the frame-side metal fitting 120 to the installation-side metal fitting 110. Through steps S114 and S115 described above, the ridge-side module support metal fitting 100 (second metal fitting) is installed in a completed state at the second installation position on the ridge side of the two pairs of metal installation positions that sandwich the solar cell module 10.

[0045] In the next step S116, the ridge-side module support bracket 100 supporting the eaves-side solar cell module 10 installed in steps S114 and S115 is used as the eaves-side module support bracket 100 supporting the ridge-side solar cell module 10. That is, the metal frame 12 of the ridge-side solar cell module 10 is inserted into the insertion gap T11 between the installation-side bracket 110 and the frame-side bracket 120 in this module support bracket 100. This insertion is performed in the same manner as in step 113 described above, so that the inner edge 12c-1 abuts against the abutment protrusion 112. After this, although not shown in the figure, the same operations as in steps 114 and S115 are repeated to install the ridge-side module support bracket 100 supporting the ridge-side solar cell module 10. With the installation of this ridge-side module support bracket 100, the solar power generation facility 1 shown in FIG. 1 is completed.

[0046] The module support fitting 100, the photovoltaic power generation facility 1, and the module installation method of the first embodiment described above can provide the following effects. That is, the gap between the clamping portion 121 and the back plate mounting portion 111 of the installation side fitting 110 is restricted to the insertion gap T11 required for inserting the metal frame 12 of the solar cell module 10 by the restricting protrusion 122 of the frame side fitting 120, even if the metal frame 12 of the solar cell module 10 is not placed between them. This allows the two module support fittings 100 on the eaves side to be installed in advance in a state where there is sufficient work space for the worker before placing the solar cell module 10, and then the metal frame 12 of the solar cell module 10 can be inserted into the insertion gap T11 for installation. In addition, when the metal frame 12 is inserted into the insertion gap T11, the metal frame 12 is sandwiched between the abutment protrusion 112 of the installation side fitting 110 that abuts against the inner edge 12c-1 of the back plate portion 12c and the restricting protrusion 122 of the frame side fitting 120. This makes it possible to complete the positioning of the metal frame 12, and therefore the solar cell module 10, by the simple task of inserting the metal frame 12. In this way, the module support bracket 100 described above allows the solar cell module 10 to be easily installed with good workability.

[0047] Furthermore, according to this embodiment, when the solar cell module 10 needs to be replaced during maintenance after construction of the solar power generation facility 1, the module replacement can be easily performed with good workability as follows. That is, in this embodiment, the solar cell module 10 can be removed simply by removing the frame side metal fittings 120 of the module support metal fittings 100 on the ridge side of the solar cell module 10 to be replaced, lifting the ridge side of the solar cell module 10 to be replaced and pulling it out diagonally upward. Then, a new solar cell module 10 is inserted diagonally by lifting the ridge side into the space opened by the removal, and the eaves side is lowered, and the frame side metal fittings 120 removed during the above-mentioned removal are reattached, completing the replacement work. In this way, according to this embodiment, the module replacement can be easily performed with good workability that does not require moving solar cell modules 10 other than the one to be replaced.

[0048] Here, in this embodiment, the back plate mounting portion 111 is provided with a pressing protrusion 111h that protrudes so as to push up the back plate portion 12c mounted on the back plate mounting portion 111 and presses the metal frame 12 against the clamping portion 121. According to this configuration, the metal frame 12 inserted into the insertion gap T11 is pressed against the clamping portion 121 by the pressing protrusion 111h, so that the support strength of the module support bracket 100 can be improved.

[0049] In this embodiment, the fixing member 130 includes a fixing bolt 131 and a fastening nut 132. The bolt head 131a of the fixing bolt 131 has a polygonal columnar shape, and a head rotation prevention protrusion 111g that prevents the bolt head 131a from rotating is provided on the back surface of the back plate mounting portion 111. According to this configuration, first, by adopting the fixing member 130 that includes the fixing bolt 131 and the fastening nut 132, which are parts with good workability, the workability of the fixing work of the frame side metal fitting 120 to the installation side metal fitting 110 can be improved. In addition, the head rotation prevention protrusion 111g that abuts against the side surface of the polygonal columnar bolt head 131a can stop unintended rotation around the axis of the fixing bolt 131 during the fastening work with the fastening nut 132, so that the workability of the fixing work can be further improved.

[0050] In this embodiment, the back plate mounting portion 111 is formed with a through hole 111e through which the bolt portion 131b passes. The through hole 111e is provided with anti-rotation protrusions 111f protruding inward at four circumferential positions on the inner side of the through hole 111e so as to prevent the inserted bolt portion 131b from rotating. With this configuration, the anti-rotation protrusions 111f provided at four positions on the inner side of the through hole 111e can prevent unintended rotation around the axis of the fixing bolt 131 during the fastening operation, thereby further improving the workability of the fixing operation.

[0051] In this embodiment, the clamping portion 121 has an eave portion 123 formed at one end thereof, which is folded up away from the back plate mounting portion 111. According to this configuration, the side of the clamping portion 121 on which the eave portion 123 is provided is the insertion side of the metal frame 12, and the insertion opening has a wide opening shape that allows easy insertion, thereby improving the workability of installing the metal frame 12, that is, the solar cell module 10.

[0052] Furthermore, restricting protrusion 122 is a portion formed so that its cross section perpendicular to the direction of protrusion from clamping portion 121 is L-shaped. With this configuration, it is possible to improve the strength of restricting protrusion 122 while suppressing an increase in the weight of frame side metal fitting 120, compared to, for example, a case in which restricting protrusion 122 is formed into a cylindrical, rectangular columnar, pipe-like, or the like shape.

[0053] Furthermore, in this embodiment, the frame side fitting 120 is formed with a pair of restricting protrusions 122. With this configuration, the strength with which the insertion gap T11 between the frame side fitting 120 and the installation side fitting 110, which is restricted by the pair of restricting protrusions 122, can be maintained can be improved.

[0054] Furthermore, in this embodiment, the installation metal fitting 110 is attached to the folded-plate roof A11 via a foundation member 150 that is fixed to the folded-plate roof A11, which is the installation location. With this configuration, by preparing a foundation member suited to the shape and condition of the installation location, the installation metal fitting 110, i.e., the module support metal fitting 100, can be commonly attached to a variety of installation locations. This improves the versatility of the module support metal fitting 100.

[0055] In this embodiment, the base member 150 is provided with a rail groove 151 into which the back plate mounting portion 111 of the installation side fitting 110 is inserted from one end opening 151a, and the rail groove 151 is fixed so as to extend along the inclination direction D11 of the folded plate roof A11. In addition, a pair of opposing inner surfaces of the rail groove 151 are provided with a support protrusion 154 and a stopper protrusion 155. The support protrusion 154 is a portion that protrudes inward and supports the back plate mounting portion 111 from the groove bottom 151b side in a shelf-like manner so as to restrict the movement of the back plate mounting portion 111 inserted from the one end opening 151a toward the groove bottom 151b side. The stopper protrusion 155 is a portion that protrudes inward and abuts against the back plate mounting portion 111 from the lower side so as to restrict the sliding movement of the back plate mounting portion 111 to a further lower side at a position lower than the support protrusion 154 in the inclination direction D11. The back plate mounting portion 111 is provided with a pair of side end portions 111b supported by the support protrusion 154 inside the rail groove 151, and a pair of abutting end portions 111c abutting against the stopper protrusion 155. According to this configuration, the back plate mounting portion 111 can be inserted into the rail groove 151 of the base member 150 by sliding in a manner that effectively prevents the back plate mounting portion 111 from dropping toward the groove bottom 151b side, since the pair of side end portions 111b are supported by the support protrusion 154. Furthermore, by the pair of contact ends 111c contacting the stopper projections 155, it is possible to effectively prevent the back plate mounting portion 111 from slipping in the inclined direction D11 and falling off the base member 150.

[0056] In addition, since the above-mentioned module support bracket 100 is used to support the solar cell module 10 in the solar power generation facility 1 of this embodiment shown in Figure 1, the solar cell module 10 can be easily installed with good workability.

[0057] 9 and 10, the above-mentioned module support bracket 100 is used to support the solar cell module 10 at the installation location. Therefore, according to the module installation method of the present embodiment, the solar cell module 10 can be easily installed with good workability.

[0058] In addition, by repeating this module installation method, it is possible to arrange a plurality of solar cell modules 10 (two in this embodiment) as follows under good workability. That is, one of the pair of module support fittings 100 supporting the solar cell module 10 can be regarded as the first fitting installed in a completed state for supporting the second solar cell module 10 to be arranged adjacent to it. In other words, the state in which the installation of the first solar cell module 10 is completed can be regarded as the state in which the first fitting installation process in the installation of the second solar cell module 10 is completed. Therefore, by continuously performing the above-mentioned module arrangement process and second fitting installation process, the second solar cell module 10 can be installed in the same manner as the first solar cell module 10. In this way, by repeating the module installation method while regarding the module support fitting 100 of the installed solar cell module 10 as the first fitting for the next solar cell module 10, it is possible to arrange a plurality of solar cell modules 10.

[0059] Here, in this embodiment, in the first fitting installation step (steps S11 and S12) and the second fitting installation step (steps S14 and S14), the frame side fitting 120 is fixed while preventing rotation of the frame side fitting 120 using an anti-rotation jig 140. According to this configuration, the frame side fitting 120 is fixed to the installation side fitting 110 while preventing rotation of the frame side fitting 120 using the anti-rotation jig 140, thereby improving the workability of the fixing work.

[0060] Next, a second embodiment will be described. This second embodiment is similar to the first embodiment described with reference to Figures 1 to 10, except for the roof as the installation location and the base member for fixing the module support bracket 100 to the roof. Below, the second embodiment will be described, focusing on the differences from the first embodiment.

[0061] FIG. 11 is a side view showing the solar power generation facility of the second embodiment.

[0062] The photovoltaic power generation facility 2 of the second embodiment shown in Fig. 11 is installed on a slate roof A21, which is a type of inclined roof. A base member 250 for fixing the module support bracket 100 is a member suitable for installation on the slate roof A21. The base member 250 is fixed onto the slate roof A21, and the module support bracket 100 is attached to the base member 250, which supports the solar cell module 10.

[0063] Next, a module construction method for the slate roof A21 in this embodiment will be described.

[0064] Fig. 12 is a schematic diagram showing steps S211 to S213 in the module construction method for the slate roof shown in Fig. 11. Also, Fig. 13 is a schematic diagram showing steps S214 to S216 in the module construction method. Note that in Figs. 12 and 13, the slate roof A21 is omitted from the illustration.

[0065] In step S211 of the module construction method, the module support fittings 100 are attached to each of the foundation members 250 on the eaves side of the slate roof A21 shown in Fig. 11. In this attachment, first, the back plate placement portion 111 of the installation side fitting 110 is inserted and fitted into the foundation member 250 in the insertion direction D13. After that, the frame side fitting 120 is attached in the attachment direction D14 so that the fixing bolt 131 penetrates the clamping portion 121 and the restricting protrusion 122 abuts against the foundation member 250. Furthermore, the fastening nut 132 is lightly screwed onto the bolt portion 131b in a state before torque tightening.

[0066] In the next step S212, with the rotation of the frame-side fitting 120 stopped by the anti-rotation jig 140, the fastening nut 132 is torqued and the frame-side fitting 120 is fastened and fixed to the installation-side fitting 110. At this time, the adjacent foundation member 250 on the ridge side has not yet had the module support fitting 100 attached.

[0067] Steps S211 and S212 up to this point constitute a first fitting installation process for installing a first fitting, which is the eaves-side module support fitting 100, in a first installation position on the eaves side.

[0068] Step S213 following the first metal fitting installation steps of steps S211 and S212 is a module placement step in which the solar cell module 10 on the eaves side is placed. In this step S213, the metal frame 12 is inserted into the insertion gap T11 of the module support metal fitting 100, which is the first metal fitting, so that the inner edge 12c-1 abuts against the abutment protrusion 112, and the solar cell module 10 is placed. Also, at this time, the ridge side end of the solar cell module 10 is placed on the foundation member 250 on the ridge side to which the module support metal fitting 100 is not attached. Specifically, the metal frame 12 is inserted into the insertion gap T11 while the ridge side of the solar cell panel 10 is lifted and held slightly obliquely, and then the ridge side is lowered onto the foundation member 250, and the solar cell panel 10 is placed. During this descent, the inner edge 12c-1 of the metal frame 12 abuts against the abutment protrusion 112 to be positioned.

[0069] Following the module placement process of step S213, steps S214 and S215 are executed to perform a second fitting installation process of installing the module support fitting 100 on the foundation member 250 on the ridge side. First, in step S214, the installation side fitting 110 is attached to each of the two foundation members 250 on the ridge side so as to be adjacent to the ridge side of the metal frame 12 of the solar cell module 10. In step S214, the back plate placement portion 111 of the installation side fitting 110 is inserted and fitted into the foundation member 250 in the insertion direction D13. In the next step S215, the frame side fitting 120 is attached in the attachment direction D14 so that the fixing bolt 131 penetrates the clamping portion 121 and the restricting protrusion 122 abuts against the foundation member 250. Thereafter, the fastening nut 132 is screwed onto the fixing bolt 131, and the fastening nut 132 is torque-tightened in a state in which the frame side fitting 120 is prevented from rotating by the anti-rotation jig 140. This torque tightening fixes the frame-side fitting 120 to the installation-side fitting 110. Through steps S214 and S215 described above, the ridge-side module support fitting 100 (second fitting) is installed in a completed state at the second installation position on the ridge side.

[0070] In the following step S216, the metal frame 12 of the second ridge-side solar cell module 10 is inserted into the insertion gap T11 between the installation-side metal fitting 110 and the frame-side metal fitting 120 of the ridge-side module support metal fitting 100 installed in steps S214 and S215. This insertion is performed in the same manner as in step 113 described above, so that the inner edge 12c-1 abuts against the abutment protrusion 112. After this, although not shown in the figures, the same operations as in steps S214 and S215 are repeated to install the ridge-side module support metal fitting 100 that supports the ridge-side solar cell module 10. With the installation of this ridge-side module support metal fitting 100, the solar power generation facility 2 shown in FIG. 11 is completed.

[0071] It goes without saying that in the second embodiment described above, similarly to the first embodiment, the solar cell module 10 can be easily installed with good workability.

[0072] Next, a third embodiment will be described. In this third embodiment, the shape of the frame side metal fittings is different from that of the first embodiment. Below, the third embodiment will be described focusing on the differences from the first embodiment. On the other hand, the photovoltaic power generation equipment and the construction method are substantially the same as those of the first embodiment, so illustrations and explanations will be omitted.

[0073] Fig. 14 is a three-view diagram similar to Fig. 4, showing a module support bracket and a base member of the third embodiment. In Fig. 14, components equivalent to those of the first embodiment shown in Fig. 4 are given the same reference numerals as in Fig. 4, and duplicated explanations of those equivalent components will be omitted below.

[0074] In the module support fitting 300 of the third embodiment, the pair of regulating projections 322 on the frame side fitting 320 are formed so that their protruding ends have a regulating end 322a and a rotation-preventing end 322b. The regulating end 322a is a portion that abuts against the upper wall 156 of the base member 150, which is the abutting object, and thereby regulates the gap between the frame side fitting 320 and the installation side fitting 110, as in the first embodiment. The rotation-preventing end 322b extends further from the regulating end 322a and abuts against a side surface of the base member 150 near the upper wall 156, thereby preventing the frame side fitting 320 from rotating.

[0075] It goes without saying that in the third embodiment described above, similarly to the first embodiment, the solar cell module 10 can be easily installed with good workability.

[0076] In this embodiment, the protruding end of the restricting projection 322 is formed to have a restricting end 322a and an anti-rotation end 322b. With this configuration, the anti-rotation jig 140 described in the first embodiment and the like are not required to prevent rotation of the frame side metal fitting 320, thereby reducing operating costs.

[0077] Next, the fourth embodiment will be described. In this fourth embodiment, the roof as the installation location, and the shapes of the foundation member and installation side metal fittings are different from those of the first embodiment. Below, the fourth embodiment will be described focusing on the differences from the first embodiment. On the other hand, the solar power generation equipment and the construction method are substantially the same as those of the first embodiment, so illustrations and explanations are omitted.

[0078] Fig. 15 is a three-view diagram similar to Fig. 4, showing a module support metal fitting and a base member of the fourth embodiment. Also, Fig. 16 is a three-view diagram showing the installation side metal fitting and the base member shown in Fig. 15. In Figs. 15 and 16, components equivalent to those of the first embodiment shown in Fig. 4 are given the same reference numerals as in Fig. 4, and duplicated explanations of those equivalent components will be omitted below.

[0079] In the fourth embodiment, the solar cell module 10 is installed on a seam-type folded-plate roof A41, and the base member is a seam gripping metal fitting 450 attached to the seam A411 of the seam-type folded-plate roof A41. In this embodiment, the installation side metal fitting 410 is integrally formed by sheet metal processing on the opposite side to the attachment portion 451 of the seam gripping metal fitting 450 to the seam A411 so that the metal frame 12 can be placed on the back plate placement portion 411.

[0080] The mounting portion 451 to the seam A411 is a pair of arms that can be opened and closed as shown in Fig. 16, and is fixed to the seam A111 by clamping the seam A411 from both the left and right sides and tightening it with a bolt 452 that passes through the mounting portion 451. The back plate mounting portion 411 in the installation side metal fitting 410 of the module support metal fitting 400 of this embodiment is a part in which a flat top portion connecting the upper ends of the mounting portion 451, which is a pair of arms, extends in a rectangular strip shape along the seam A411. At both ends of this back plate mounting portion 411, there are provided a contact protrusion 412 that contacts the inner edge 12c-1 of the metal frame 12 of the solar cell module 10, a contact surface 411d with the metal frame 12, and a pressing protrusion 411h that presses the metal frame 12 up against the frame side metal fitting 120. A head anti-rotation protrusion 411g that prevents the bolt head 131a from rotating is formed on the back surface of the back plate mounting portion 411, and the central through hole for attaching the fixing bolt 131 has anti-rotation protrusions 411f for the fixing bolt 131 provided in four locations, as in the first embodiment.

[0081] In this embodiment, by attaching the seam gripping fitting 450 to the seam A411, the installation side fitting 410 is automatically attached to the seam-type folded-plate roof A41. Then, the frame side fitting 120 is attached in the same procedure as in the first embodiment, and the fastening nut 132 is screwed into the fixing bolt 131 of the fixing member 130 and torque-tightened to complete the module support fitting 400. Thereafter, the metal frames 12 of the solar cell modules 10 are inserted sequentially as in the first embodiment, and the solar power generation facility in which the solar cell modules 10 are arranged on the seam-type folded-plate roof A41 is completed.

[0082] It goes without saying that in the fourth embodiment described above, similarly to the first embodiment, the solar cell module 10 can be easily installed with good workability.

[0083] In this embodiment, the installation side metal fitting 411 of the module support metal fitting 400 is integrally formed on the opposite side of the seam gripping metal fitting 450 from the attachment portion 451 to the seam A411. With this configuration, the seam gripping metal fitting 450 as a foundation member required when installing the solar cell module 10 on the seam-type folded-plate roof A41 and the installation side metal fitting 411 of the module support metal fitting 400 are integrally formed, so that the number of parts can be reduced.

[0084] Next, a fifth embodiment will be described. This fifth embodiment differs from the first embodiment only in the module construction method, and various members and installation locations are similar to those of the first embodiment. Below, the fifth embodiment will be described, focusing on the differences from the first embodiment. In the following description, illustrations of the module construction method of the fifth embodiment will be omitted, and the module construction method of the first embodiment shown in Figures 9 and 10 will be referred to as appropriate.

[0085] In the module construction method of the fifth embodiment, steps S111 and S112, in which the module support fitting 100 is installed via the foundation member 150, and steps S114 and S115 are all temporary assembly steps in which no torque tightening is performed. That is, steps S111 and S112 are first fitting temporary assembly steps in which the eaves-side module support fitting 100, which is the first fitting, is installed in a temporary assembly state in which the fastening nuts 132 are loosely fastened without torque tightening and the frame-side fitting 120 is temporarily assembled to the installation-side fitting 110. Also, steps S114 and S115 are second fitting temporary assembly steps in which the ridge-side module support fitting 100, which is the second fitting, is installed in a similar temporary assembly state.

[0086] In this embodiment, after all six module support fittings 100 supporting two solar cell modules 10 are installed in a provisionally assembled state, the following final assembly process is performed. In this final assembly process, the frame side fittings 120 of each of the six module support fittings 100 in the provisionally assembled state are finally assembled to the installation side fitting 110 by torque tightening of the fastening nuts 132. In this embodiment, the frame side fittings 120 are assembled to the installation side fitting 110 using the above-mentioned anti-rotation jig 140 in the above-mentioned first fitting provisional assembly process and second fitting provisional assembly process. In the final assembly process, the restricting protrusions 122 of the frame side fittings 120 abut against the metal frame 12 of the solar cell module 10. Since the frame side fittings 120 are already prevented from rotating by this abutment, the anti-rotation jig 140 is not used in the final assembly process in this embodiment, but the anti-rotation jig 140 may be used just to be sure.

[0087] It goes without saying that in the fifth embodiment described above, similarly to the first embodiment, the solar cell module 10 can be easily installed with good workability.

[0088] Moreover, according to this embodiment, by repeating the second metal fitting temporary assembly step, it is possible to arrange a plurality of solar cell modules 10 as follows under good workability. That is, one of the pair of module support fittings 100 that support the solar cell module 10 in a temporary assembly state can be regarded as the first metal fitting installed in a temporary assembly state for supporting the second solar cell module 10. In other words, the state in which the second metal fitting temporary assembly step for the first solar cell module 10 is completed can be regarded as the state in which the first metal fitting temporary assembly step for the installation of the second solar cell panel is completed. Therefore, by continuing the second metal fitting temporary assembly step, the second solar cell module 10 can be temporarily installed in the same manner as the first solar cell module 10. In this way, by regarding the module support fitting 100 that has been installed and is in a temporary assembly state as the first metal fitting for the next solar cell module 10 and repeating the second metal fitting temporary assembly step, it is possible to arrange a plurality of solar cell modules 10 in a temporary assembly state. In this case, the main assembly step may be performed each time the temporary installation of the adjacent solar cell module 10 is completed. Alternatively, the process may be performed collectively when the temporary assembly and installation of several solar cell modules 10 has been completed, or when the temporary assembly and installation of all the desired solar cell modules 10 has been completed.

[0089] Here, in this embodiment, the first fitting provisional assembly process and the second fitting provisional assembly process are performed using an anti-rotation jig 140. According to this configuration, the frame-side fitting 120 is assembled to the installation-side fitting 110 while preventing rotation of the frame-side fitting 120 using the anti-rotation jig 140, thereby improving the workability of the fixing operation.

[0090] Next, a sixth embodiment will be described. This sixth embodiment is a modified example of the first embodiment described with reference to Figs. 1 to 10. In the sixth embodiment, the shapes of the installation side metal fittings and the frame side metal fittings are different from those of the first embodiment. Below, the sixth embodiment will be described focusing on the differences from the first embodiment. On the other hand, the photovoltaic power generation equipment and the construction method are substantially the same as those of the first embodiment, and therefore illustrations and descriptions thereof will be omitted.

[0091] Fig. 17 is a plan view similar to Fig. 3, showing a module support metal fitting and a foundation member of the sixth embodiment, and Fig. 18 is a three-view drawing showing the module support metal fitting and the foundation member shown in Fig. 17 together with a rotation-stopping jig. Fig. 19 is a three-view drawing showing the installation side metal fitting shown in Figs. 17 and 18, and Fig. 20 is a three-view drawing showing the frame side metal fitting shown in Figs. 17 and 18. Fig. 21 is a schematic drawing showing how the installation side metal fitting and the frame side metal fitting shown in Figs. 17 and 18 are attached to the foundation member and fixed with a fixing member to form a module support metal fitting. In Figs. 17 to 21, among the components equivalent to the components of the first embodiment shown in Figs. 1 to 10, the same reference numerals as Figs. 1 to 10 are used to explain the sixth embodiment, and the following will omit redundant explanations of these equivalent components.

[0092] In the sixth embodiment, the installation location is a folded-plate roof A11 similar to that in the first embodiment. The solar cell module 10 is installed via a module support bracket 600 attached to a base member 150 fixed to the trapezoidal top portion A111 of the folded-plate roof A11, and the solar power generation facility 6 is constructed.

[0093] At this time, in this embodiment, first, two pairs of rail fitting ribs 611i are provided in the back plate placement portion 611 of the installation metal fitting 610 so as to sandwich the abutment protrusions 112 at two positions, front and rear in the longitudinal direction, in the width direction. As shown in FIG. 18, the groove slit 152 of the base member 150 is a space formed between the rail inner walls 152a extending from the inner end edges of the pair of upper walls 156 toward the groove bottom 151b. A gap is opened between each of the pair of rail inner walls 152a and a pair of side walls 157 of the base member 150. When the installation metal fitting 610 is inserted and fitted into the rail groove 151 from the one end opening 151a in the insertion direction D13 as shown in FIG. 21, the rail fitting rib 611i slides and moves in the gap between the side wall 157 while rubbing against the inner surface of the rail inner wall 152a. At this time, the abutment end 111c slides in the gap between the rail inner wall 152a while rubbing against the inner surface of the side wall 157. Furthermore, the rail fitting rib 611i and the abutment end 111c slide in the gap between the rail inner wall 152a and the side wall 157 while their upper edges abut and rub against the back surface of the upper wall 156. This sliding movement while rubbing suppresses shaking in the up-down and width directions of the installation metal fitting 610 during the movement, and the installation metal fitting 610 can be smoothly inserted and fitted into the rail groove 151.

[0094] Next, in this embodiment, the clamping portion 621 of the frame side metal fitting 620 is not provided with a structure equivalent to the eaves portion 123 in the first embodiment, and has a rectangular shape that is rotationally symmetric about an axis when viewed from above. In the center of this clamping portion 621, a rhombus-shaped bulge portion 621a in a plan view is formed by pressing to bulge upward. In the center of this bulge portion 621a, a through hole 624 is formed through which the fixing bolt 131 of the fixing member 130 passes.

[0095] The shape of the bulge formed on the clamping portion is not limited to the diamond shape as in this embodiment, and the location of the bulge is not limited to the center of the clamping portion. As long as the bulge is formed around the through hole of the fixing bolt, any shape such as a circle or an ellipse in a plan view may be adopted. The position of the bulge may be slightly closer to the edge of the clamping portion. The bulge direction is not limited to the upward direction as in this embodiment, and the bulge may be downwardly convex.

[0096] 20, a pair of regulating protrusions 622, each of which has a substantially U-shaped cross section perpendicular to the protruding direction D12, protrude from a pair of short side edges of the rectangular clamping portion 621 with a protruding length L11 corresponding to the insertion gap T11 described in the first embodiment. The pair of regulating protrusions 622 are provided so that the opening sides of the U shape face each other. Specifically, the strip-shaped protruding edge is bent at a substantially right angle at the side edge of the short side of the clamping portion 621, and a pair of lengthwise portions of the protruding edge are folded at a substantially right angle toward the center of the clamping portion 621, thereby forming a pair of substantially U-shaped regulating protrusions 622 with their opening sides facing each other.

[0097] Then, the frame-side metal fitting 620 is placed over the installation-side metal fitting 610 so that the fixing bolt 131 of the installation-side metal fitting 610 attached to the foundation member 150 as described above passes through the through-hole 624. At this time, the tips of the pair of substantially U-shaped regulating protrusions 622 come into contact with the upper wall 156 of the foundation member 150, and an insertion gap T11 into which the metal frame 12 of the solar cell module 10 is inserted is formed between the frame-side metal fitting 620 and the installation-side metal fitting 610. Thereafter, the fastening nut 132 is screwed onto the fixing bolt 131 that has passed through the through-hole 624, thereby fastening and fixing the frame-side metal fitting 620 to the installation-side metal fitting 610, thereby forming the module support metal fitting 600. During this fastening and fixing, the anti-rotation jig 140 is placed so as to abut against the pair of regulating protrusions 622, and the fastening nut 132 is tightened in a state in which the frame-side metal fitting 620 is prevented from rotating, as in the first embodiment. The base member 150 having the module support bracket 600 configured in this manner is fixed to the folded plate roof A11 and used for installing the solar cell module 10.

[0098] It goes without saying that in the sixth embodiment described above, similarly to the first embodiment, the solar cell module 10 can be easily installed with good workability.

[0099] In this embodiment, the installation metal fitting 610 is attached to the base member 150 so that the rail fitting rib 611i and the contact end 111c of the installation metal fitting 610 slide in the gap between the rail inner wall 152a and the side wall 157 of the base member 150. With this configuration, shaking of the installation metal fitting 610 during movement is suppressed, and the installation metal fitting 610 can be smoothly inserted and fitted into the rail groove 151 in the base member 150, as described above.

[0100] Furthermore, according to this embodiment, the clamping portion 621 of the frame side metal fitting 620 is formed rotationally symmetrically around the axis, eliminating the need for directional installation, and the worker can perform installation work without worrying about the orientation of the frame side metal fitting 620.

[0101] Furthermore, according to this embodiment, the pair of restricting protrusions 622 on the frame side fitting 620 are formed with a generally U-shaped cross section, thereby improving the strength in the protruding direction D12.

[0102] According to this embodiment, the frame side metal fitting 620 has a bulging portion 621a formed in the clamping portion 621. The fastening nut 132 is screwed onto the fixing bolt 131 that passes through the through hole 624 provided in the bulging portion 621a, and is then tightened to fasten the frame side metal fitting 620 to the installation side metal fitting 610. At this time, the fastening force of the fastening nut 132 is applied to the peripheral portion of the through hole 624. In this embodiment, the peripheral portion of the through hole 624 becomes the bulging portion 621a, improving the strength, so that the fastening force of the fastening nut 132 can effectively suppress deformation, such as the pair of restricting protrusions 622 opening in a direction away from each other. The frame side metal fitting 620 in this embodiment can be used in place of the frame side metal fitting 120 in the module support metal fitting 100 for the slate roof A21 of the second embodiment shown in Figs. 11 to 13. In addition, the frame side fitting 620 in this embodiment can also be used in place of the frame side fitting 120 in the module support fitting 400 for the grooved seam-type folded plate roof A41 of the fourth embodiment shown in Figures 15 and 16.

[0103] Next, a seventh embodiment will be described. This seventh embodiment is a modification of the first embodiment described with reference to Figs. 1 to 10, in particular a modification of the solar power generation facility 1 shown in Fig. 1. The seventh embodiment will be described below, focusing on the differences from the first embodiment. On the other hand, the module support fittings and the construction method are substantially the same as those of the first embodiment, and therefore illustrations and descriptions thereof will be omitted.

[0104] FIG. 22 is a top view similar to FIG. 1 showing a solar power generation facility according to the seventh embodiment.

[0105] The solar power generation facility 7 of the seventh embodiment is a solar cell module 10 installed on a folded-plate roof A11 similar to that of the first embodiment via a module support bracket 100 similar to that of the first embodiment. In this embodiment, a back support member 760 is further installed to support the back surface 11b of the module body 11 of the solar cell module 10, which is opposite to the light receiving surface 11a. The back support member 760 is attached to a support position away from the attachment position of the installation side bracket 110 on the folded-plate roof A11, and supports the supported portion 11b-1 away from the metal frame 12 on the back surface 11b of the module body 11. In this embodiment, two back support members 760 are installed so as to support two supported portions 11b-1 for one solar cell module 10. The back support member 760 plays a role of supporting the snow load applied to the light receiving surface 11a from the back surface 11b when snow accumulates.

[0106] FIG. 23 is a three-view diagram showing the rear surface support member shown in FIG.

[0107] The back support member 760 is attached to the folded plate roof A11 via the foundation member 150 similar to that of the first embodiment, and includes a back installation side metal fitting 761, a cushioning member 762, a fixing metal fitting 763, and a fixing member 764. The back installation side metal fitting 761 has the same shape as the installation side metal fitting 110 similar to that of the first embodiment provided for installing the solar cell module 10, and is attached to the support position on the folded plate roof A11 via the foundation member 150. The cushioning member 762 is formed of an elastic resin such as rubber, which is a material more flexible than the module body 11 and the back installation side metal fitting 761, and is attached to the surface of the supported portion 11b-1 of the module body 11, and when a snow load is applied, it supports the snow load while being slightly crushed. The fixing metal fitting 763 is disposed between the cushioning member 762 and the back installation side metal fitting 761, and fixes the cushioning member 762 to the back installation side metal fitting 761.

[0108] FIG. 24 is a perspective view showing the buffer member and the fixing metal fitting shown in FIG.

[0109] As shown in Figs. 23 and 24, the cushioning member 762 is a rectangular block-shaped member, and one surface of the cushioning member 762 is attached to the supported portion 11b-1. The fixing metal fitting 763 includes a U-shaped groove-shaped fixed portion 763a that is placed on and fixed to the upper surface of the back-side installation side metal fitting 761, and a pair of cushioning member fixing portions 763b that extend in a wing-like manner from a pair of upper end edges of the fixed portion 763a. The back surface of the cushioning member 762 opposite to the side that is attached to the supported portion 11b-1 is adhesively fixed to the cushioning member fixing portion 763b. The fixing member 764 fixes the fixed portion 763a of the fixing metal fitting 763 to the upper surface of the back-side installation side metal fitting 761, and includes a fixing bolt 764a and a fastening nut 764b as shown in Fig. 23. The fixing bolt 764a is attached so that the bolt head 764a-1 slides against the back surface of the back-side installation side metal fitting 761, which has the same shape as the installation side metal fitting 110. On the other hand, a through hole 763a-1 for bolt fixing is provided in the bottom surface of the U-shaped groove-shaped fixed portion 763a, and a fastening nut 764b is attached to a bolt portion 764a-2 that passes through this through hole 763a-1.

[0110] It goes without saying that in the seventh embodiment described above, similarly to the first embodiment, the solar cell module 10 can be easily installed with good workability.

[0111] Moreover, in this embodiment, the solar power generation equipment 7 is provided with a back surface support member 760. According to this configuration, the load of snow when snow accumulates is supported by the back surface support member 760, so that deflection of the module body 11 due to the load of snow can be suppressed.

[0112] In this embodiment, the rear surface support member 760 has a structure in which a cushioning member 762 is fixed to a rear surface installation side metal fitting 761 having the same shape as the installation side metal fitting 110 for installing the solar cell module 10 by a fixing metal fitting 763. According to this configuration, the installation side metal fitting 110 for installing the solar cell module 10 can be used as the rear surface installation side metal fitting 761, which is one component of the rear surface support member 760, so that the parts cost can be reduced.

[0113] In this embodiment, the rectangular block-shaped buffer member 762 is exemplified as an example of the buffer member, but the buffer member is not limited to this. The buffer member may be, for example, a circular block-shaped member, and the specific shape is not important.

[0114] In addition, in the present embodiment, as an example of a solar power generation facility, a solar power generation facility 7 in which two sets of back surface support members 760 are installed for each solar cell panel 10 is illustrated. However, the solar power generation facility is not limited to this, and the number of sets of back surface support members can be appropriately set according to the amount of snowfall expected at the installation location, etc.

[0115] The above-mentioned circumstances regarding the shape of the cushioning member and the number of sets of the back surface support member also apply to the eighth to tenth embodiments described below that include a back surface support member like this embodiment.

[0116] Next, an eighth embodiment will be described. This eighth embodiment is a modification of the solar power generation facility in the fourth embodiment described with reference to Figs. 15 and 16, in which a back support member for supporting snow load is provided. The eighth embodiment will be described below, focusing on the differences from the fourth embodiment. On the other hand, the module support fittings and the construction method are substantially the same as those of the fourth embodiment, and therefore illustrations and descriptions thereof will be omitted.

[0117] FIG. 25 is a diagram illustrating the solar power generation system according to the eighth embodiment, focusing on the back surface supporting member.

[0118] In the solar power generation facility 8 of the eighth embodiment, the solar cell module 10 is installed on the seam-type folded plate roof A41 via the seam gripping metal fitting 450 using the module support metal fitting 400 of the fourth embodiment shown in FIG. 15 and FIG. 16. In this embodiment, a back support member 860 for supporting snow load is installed on the back side of the module body 11 of the solar cell module 10. The back installation side metal fitting 861 of this back support member 860 has the same shape as the installation side metal fitting 410 similar to the fourth embodiment, and is integrally formed with the seam gripping metal fitting 450 by sheet metal processing. The buffer member 862 and the fixing metal fitting 863 in this embodiment are the same members as those in the seventh embodiment described above, and are fixed to the back installation side metal fitting 861 by the fixing member 864 having the fixing bolt 864a and the fastening nut 864b.

[0119] It goes without saying that in the eighth embodiment described above, similarly to the first embodiment, the solar cell module 10 can be easily installed with good workability.

[0120] Also in this embodiment, similarly to the above-described seventh embodiment, the provision of the rear surface support member 860 can suppress deflection of the module body 11 due to the load of snow.

[0121] Next, a ninth embodiment will be described. In this ninth embodiment, a solar cell module 10 is installed on a flat roof. In order to enable installation on a flat roof, the module support bracket is different from the previous embodiments, but the technical concept of having an installation side bracket, a frame side bracket, and a fixing member is the same, and detailed description of the module support bracket will be omitted. Also, the construction method, etc. are substantially the same as the first embodiment, so illustrations and descriptions will be omitted.

[0122] FIG. 26 is a diagram showing a solar power generation facility according to the ninth embodiment.

[0123] In the solar power generation facility 9 of the ninth embodiment, the solar cell module 10 is installed on the flat roof A91 by the module support bracket 900 via the base 950. The solar cell module 10 is installed on the flat flat roof A91 with an inclination suitable for receiving light. In this embodiment, in order to provide this inclination, a low-side support bracket 900L and a high-side support bracket 900H are prepared as the module support bracket 900. These two types of support brackets have the same structure except for the height from the base 950. That is, the low-side support bracket 900L and the high-side support bracket 900H each include the installation side bracket 910L, 910H, the frame side bracket 920L, 920H, and the fixing member 930L, 930H. The installation side metal fittings 910L, 910H are formed in a Z-shape in a side view and fixed to the base 950, and the part that hits the upper side of the Z-shape is inclined at a desired inclination angle, and this part supports the metal frame 12 of the solar cell module 10 from the back side. The frame side metal fittings 920L, 920H are arranged so as to sandwich the metal frame 12 between the installation side metal fittings 910L, 910H. Here, the installation side metal fittings 910L, 910H are subjected to downwardly convex burring processing on the mounting part of the metal frame 12, and a screw hole having a female thread is formed on the inside. And, the fixing members 930L, 930H of this embodiment are fixing bolts, and the fixing bolts are screwed into the screw holes of the installation side metal fittings 910L, 910H from above the frame side metal fittings 920L, 920H, aiming at the screw holes of the installation side metal fittings 910L, 910H. As a result, the frame side metal fittings 920L, 920H, with the metal frame 12 sandwiched between them and the installation side metal fittings 910L, 910H, are fixed to the installation side metal fittings 910L, 910H by the fixing members 930L, 930H serving as fixing bolts.

[0124] In this embodiment, as in the seventh and eighth embodiments described above, a back support member 960 is provided to support the module body 11 of the solar cell module 10 from the back side in order to support the snow load. Two types of back support members 960 are provided: a low-side support member 960L provided on the low side of the slope, and a high-side support member 960H provided on the high side. These two types of support members have the same structure except for the height from the base 950, and in the following description, the high-side support member 960H is used as a representative example and is simply referred to as the back support member 960.

[0125] FIG. 27 is a side view and a rear view of the back support member shown in FIG.

[0126] The back support member 960 is attached to the flat roof A91 via a base 950 in the same manner as the above-mentioned module support bracket 900, and includes a back installation side bracket 961, a buffer member 962, a fixing bracket 963, and a fixing member 964. The back installation side bracket 961 has a Z-shape in side view, the same as the installation side bracket provided for installing the solar cell module 10, and is attached to a support position on the flat roof A91 via the base 950. This back installation side bracket 961 is fixed to the base 950 by an anchor bolt 951. Although omitted in the description referring to FIG. 26, the installation side brackets 910L and 910H of the module support bracket 900 are also fixed to the base 950 by an anchor bolt 951.

[0127] The buffer member 962 is formed in a rectangular block shape from elastic resin such as rubber, comes into contact with the supported portion 11b-1 of the module body 11, and when a snow load is applied, it supports the snow load while being slightly crushed. The fixing metal fitting 963 is disposed between the buffer member 962 and the rear surface installation side metal fitting 961, and fixes the buffer member 962 to the rear surface installation side metal fitting 961. The fixing member 964 is a fixing bolt, and is screwed through the fixing metal fitting 963 into a screw hole formed in the rear surface installation side metal fitting 961 by burring. In this way, the fixing metal fitting 963 is fixed to the rear surface installation side metal fitting 961. The buffer member 962 is adhesively fixed to the fixing metal fitting 963.

[0128] It goes without saying that in the ninth embodiment described above, similarly to the first embodiment, the solar cell module 10 can be easily installed with good workability.

[0129] Also in this embodiment, similarly to the seventh and eighth embodiments described above, the provision of the rear surface support member 960 can suppress deflection of the module body 11 due to the load of snow.

[0130] Next, a tenth embodiment will be described. In this tenth embodiment, a solar cell module 10 is installed on a metal roof. In order to enable installation on a metal roof, the module support bracket is different from the previous embodiments, but the technical concept of having an installation side bracket, a frame side bracket, and a fixing member is the same, and detailed description of the module support bracket will be omitted. Also, the construction method, etc. are substantially the same as in the first embodiment, so illustrations and explanations will be omitted.

[0131] FIG. 28 is a diagram showing a solar power generation facility according to the tenth embodiment.

[0132] In the solar power generation facility 16 of the tenth embodiment, the solar cell module 10 is installed on a metal horizontal roof A161 by a module support bracket 160 via a foundation member 170. The foundation member 170 includes a groove rail-shaped horizontal vertical slat 171 and a pair of slat support brackets 172. The pair of slat support brackets 172 are bonded and fixed to the metal horizontal roof A161 so as to support both ends of the horizontal vertical slat 171, and each end of the horizontal vertical slat 171 is fixed to each slat support bracket 172 to form the foundation member 170. The module support bracket 160 includes an installation side bracket 161, a frame side bracket 162, and a fixing member 163 fixed to the foundation member 170. The installation side bracket 161 is inserted and fixed longitudinally inside the groove rail-shaped horizontal vertical slat 171, and supports the metal frame 12 of the solar cell module 10 from the back side. The frame-side metal fitting 162 is disposed so as to sandwich the metal frame 12 between it and the installation-side metal fitting 161. Then, a fixing member 163 having a fixing bolt and a fastening nut fixes the frame-side metal fitting 162, with the metal frame 12 sandwiched between it and the installation-side metal fitting 161, to the installation-side metal fitting 161.

[0133] The method of fixing the rail support bracket 172 is not limited to adhesive fixing as in this embodiment. The method of fixing the rail support bracket 172 may be other than adhesive fixing, for example, fixing with wood screws, depending on the shape of the metal roof to which it is fixed.

[0134] Also in this embodiment, similarly to the seventh to ninth embodiments described above, a back surface support member 180 is provided that supports the back surface of the module body 11 of the solar cell module 10 in order to support the load of snow.

[0135] FIG. 29 is a three-view diagram showing the rear support member shown in FIG.

[0136] The back surface support member 180 is attached to the metal horizontal roof A161 via a foundation member 170 in the same manner as the above-mentioned module support bracket 160, and includes a back surface installation side bracket 181, a buffer member 182, a fixing bracket 183, and a fixing member 184. The back surface installation side bracket 181 has the same shape as the installation side bracket 161 provided for installing the solar cell module 10, and is attached to a support position on the metal horizontal roof A161 via the foundation member 170. This back surface installation side bracket 181 is inserted and fixed inside the groove rail-shaped horizontal roof vertical battens 171 fixed to the metal horizontal roof A161 by the batten support brackets 172 on the foundation member 170.

[0137] The buffer member 182 is formed in a rectangular block shape from elastic resin such as rubber, and is in contact with the supported portion 11b-1 of the module body 11. When snow load is applied, the buffer member 182 supports the snow load while being slightly crushed. The fixing bracket 183 is disposed between the buffer member 182 and the rear surface installation side metal fitting 181, and fixes the buffer member 182 to the rear surface installation side metal fitting 181. The fixing member 184 includes a fixing bolt 184a and a fastening nut 184b. The fixing bolt 184a is attached so that the bolt head 184a-1 is in sliding contact with the rear surface installation side metal fitting 181. The bolt portion 184a-2 of the fixing bolt 184a penetrates the fixing bracket 183 and the fastening nut 184b is tightened, thereby fixing the fixing bracket 183 to the rear surface installation side metal fitting 181. The buffer member 182 is adhesively fixed to the fixing bracket 183.

[0138] It goes without saying that in the tenth embodiment described above, similarly to the first embodiment, the solar cell module 10 can be easily installed with good workability.
