Description

[Technical field]

[0001] The present invention relates to a solar panel clamp used for fixing a solar panel onto a roof, and a solar panel fixing device equipped with this solar panel clamp. [Background technology]

[0002] A conventional structure for fixing solar panels to a roof involves fixing multiple solar panel mounting brackets onto the roof, placing two solar panels side-by-side on a mounting plate provided on the upper part of the multiple solar panel mounting brackets, with the outer edges of the two solar panels butting against each other, and then clamping and fixing the outer edges of the two solar panels placed on the mounting plate from above with a panel clamping portion at both ends using a single clamping bracket attached to the solar panel mounting bracket via a fixing bolt erected on the mounting plate (by tightening a fixing nut screwed onto the fixing bolt) (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2020-29732 Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, reused solar panels are often used in the construction of solar facilities to reduce costs.

[0005] However, when using reused panels, it can be difficult to obtain the required number of panels from the same manufacturer, and it is often necessary to use reused panels from different manufacturers at the same site.

[0006] As the height (thickness) dimensions of solar panels vary depending on the manufacturer, especially in the case of a fixing structure in which two solar panels of different heights are lined up as described above and the outer edges of both panels are held down and fixed with both ends of a single clamp, it is not easy to create panel holding portions at both ends of a single clamp that can accommodate the different heights, and it was difficult to handle this on site.

[0007] The present invention seeks to identify and solve the problems associated with using reusable panels in constructing solar equipment using such solar panel clamping fittings, and to provide a solar panel clamping fitting that can easily accommodate on-site fixing of two solar panels of different heights (reusable panels) by using separate fittings rather than holding down two solar panels with a single clamping fitting, as well as a solar panel fixing device equipped with this solar panel clamping fitting. [Means for solving the problem]

[0008] The gist of the present invention will now be described with reference to the accompanying drawings.

[0009] A mounting portion 5 is provided on the upper portion of a metal fitting body 2 that can be fixed onto a roof 1, on which two solar panels 3 can be placed side by side with their outer edge portions 4 butted together, and fixing bolts 6 are provided in an upright position to fix the two solar panels 3 placed on the mounting portion 5 to the metal fitting body 2. The solar panel mounting fitting A is attached to the solar panel mounting fitting A by the fixing bolts 6 of the solar panel mounting fitting A. A solar panel pressing bracket P has a bolt hole 7 through which the fixing bolt 6 passes, and a panel pressing portion 8 capable of pressing from above the outer edge portion 4 of the solar panel 3 placed on the placement portion 5, and is attached to the solar panel mounting bracket A by passing the fixing bolt 6 through the bolt hole 7 and screwing a fixing nut 9 onto the fixing bolt 6 protruding upward from the bolt hole 7, and is configured so that the outer edge portions 4 of two solar panels 3 placed on the placement portion 5 are pressed and fixed by the panel pressing portion 8 when the fixing nut 9 is tightened. The solar panel clamp P is a first pressing fitting P1 provided with the panel pressing portion 8 for pressing and fixing an outer edge portion 4 of one of the two solar panels 3 placed side by side on the mounting portion 5 of the solar panel mounting fitting A on a lower base 10 having the bolt holes 7; The solar panel mounting bracket A is provided with a second pressing bracket P2, which is provided with an upper base 11 that can be stacked on the lower base 10 and has a bolt hole 7 through which the fixing bolt 6 passes, the bolt hole 7 being communicated with the bolt hole 7 of the first pressing bracket P1, and which has the panel pressing portion 8 that presses and fixes the outer edge portion 4 of the other of the two solar panels 3 that are placed side by side on the placement portion 5 of the solar panel mounting bracket A; The first pressing fitting P1 and the second pressing fitting P2 relate to a solar panel pressing fitting characterized in that when the upper layer substrate 11 of the second pressing fitting P2 is laminated on the lower layer substrate 10 of the first pressing fitting P1, the respective panel pressing portions 8 are arranged at different heights, and the outer edge portions 4 of the two solar panels 3 of different heights placed side by side on the mounting portion 5 of the solar panel mounting fitting A are pressed and fixed by the panel pressing portions 8 of the first pressing fitting P1 and the panel pressing portions 8 of the second pressing fitting P2, which are at different heights.

[0010] In addition, the first pressing fitting P1 has the panel pressing portion 8 protruding from an end portion of the lower base 10, The second pressing fitting P2 has the panel pressing portion 8 protruding from an end portion of the upper base 11, and the upper base 11 is configured so that it can be stacked on the lower base 10 of the first pressing fitting P1 when the panel pressing portion 8 of the second pressing fitting P2 is oriented in the opposite direction to the panel pressing portion 8 of the first pressing fitting P1, This relates to the solar panel clamping bracket described in claim 1, characterized in that the outer edge portions 4 of the two solar panels 3 of different heights placed side by side on the placement portion 5 of the solar panel mounting bracket A are held down and fixed by the panel clamping portion 8 of the first clamping bracket P1 and the panel clamping portion 8 of the second clamping bracket P2, which protrude in opposite directions during stacking.

[0011] In addition, the first pressing member P1 has a lower base 10 formed in a flat plate shape, The second pressing member P2 has the upper base 11 formed in a flat plate shape, The solar panel pressing fixture according to claim 1, characterized in that it is configured so that the flat upper layer substrate 11 can be laminated on the flat lower layer substrate 10.

[0012] In addition, a fulcrum protrusion 12 is provided on the lower surface of the end of the upper base 11 of the second pressing fitting P2 opposite to the panel pressing portion 8, the fulcrum protrusion 12 contacting the upper surface of the lower base 10 of the first pressing fitting P1, This relates to the solar panel clamping fitting described in claim 1, characterized in that when this upper layer substrate 11 is stacked on the lower layer substrate 10 and the fixing nut 9 is tightened, the upper layer substrate 11 tilts around the fulcrum protrusion 12 in contact with the lower layer substrate 10 as a fulcrum, and the panel clamping portion 8 of the second clamping fitting P2 is guided downwardly and downwardly, and the outer edge portion 4 of the solar panel 3 is pressed down and fixed by this descending panel clamping portion 8.

[0013] The present invention also relates to a solar panel fixing device comprising a solar panel mounting bracket A having a mounting portion 5 on the upper part of a bracket main body 2 that can be fixed onto a roof 1, on which two solar panels 3 can be placed with their outer edge portions 4 butted together, and fixing bolts 6 provided in an upright position for fixing the two solar panels 3 placed on the mounting portion 5 to the bracket main body 2, and a solar panel holding bracket P described in any one of claims 1 to 4. Effect of the Invention

[0014] Since the present invention is configured as described above, the outer edges of two solar panels of different heights that are placed side by side on the mounting portion of the solar panel mounting bracket are held down and fixed by two brackets, the first and second clamping brackets, which have panel clamping portions of different heights, so that it is easy to line up and hold down solar panels of different heights (such as reused panels) on site.Furthermore, since the first clamping bracket of the present invention has the same configuration as a so-called ``end'' clamping bracket for holding down and fixing the outer edges of solar panels that are lined up at the very edge of a roof, this ``end'' clamping bracket, i.e., an existing clamping bracket, can be used as a substitute for the first clamping bracket.Therefore, the present invention is a solar panel clamping bracket that is extremely practical, as it can be easily designed and realized because it is sufficient to simply add the second clamping bracket to an existing ``end'' clamping bracket.

[0015] Furthermore, in the invention described in claim 2, the solar panel clamping bracket has an even more practical configuration in which the first and second clamping brackets can be easily designed and realized with a simple configuration, and can securely hold down and fix the outer edges of two solar panels of different heights that are placed side by side on the mounting portion of the solar panel mounting bracket.

[0016] Furthermore, the invention described in claim 3 provides a solar panel pressing fitting with an even more practical configuration, in which the upper base of the second pressing fitting can be easily and reliably stacked on the lower base of the first pressing fitting.

[0017] In addition, in the invention described in claim 4, when the fixing nut is tightened, the panel pressing portion of the second pressing bracket is guided downward by the fulcrum convex portion, and this downward moving panel pressing portion enables the outer edge of the solar panel to be more firmly pressed down and fixed by the second pressing bracket, resulting in a solar panel pressing bracket with an extremely practical configuration.

[0018] Furthermore, the invention according to claim 5 provides a highly practical solar panel fixing device equipped with a solar panel pressing metal fitting that exerts the above-mentioned functions and effects. [Brief description of the drawings]

[Diagram 2] FIG. 2 is an oblique view showing the solar panel fixing device of the present embodiment, in which the solar panel pressing metal fitting is disassembled from the solar panel mounting metal fitting and the orientation of the second pressing metal fitting is changed. [Diagram 3] FIG. 2 is an explanatory enlarged side view with a portion cut away, showing the state of use of this embodiment (state in which the solar panel is fixed to the roof). DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] BEST MODE FOR CARRYING OUT THE PRESENT DISCLOSURE The preferred embodiment of the present invention will be briefly described with reference to the accompanying drawings, which show the operation of the present invention.

[0021] For example, first, the solar panel mounting bracket A is fixed onto the roof 1 by the bracket body 2 , and then the outer edge portions 4 of the two solar panels 3 are placed on the mounting portions 5 provided on the upper part of the bracket body 2 .

[0022] Next, the fixing bolt 6, which is provided in an upright state at the top of the metal body 2, is passed through the bolt hole 7 of this solar panel pressing metal fitting P, and a fixing nut 9 is screwed onto the fixing bolt 6 protruding upward from this bolt hole 7, thereby attaching this solar panel pressing metal fitting P to the solar panel mounting metal fitting A. When the fixing nut 9 screwed onto the fixing bolt 6 is tightened, the panel pressing portion 8 of the solar panel pressing metal fitting P presses down and fixes the outer edge portions 4 of each of the two solar panels 3 placed on the mounting portion 5. The solar panel pressing metal fitting P of the present invention can hold down and fix multiple solar panels 3 of different heights (thicknesses) (for example, reused panels from different manufacturers) in a line.

[0023] Specifically, the solar panel clamping bracket P of the present invention comprises a first clamping bracket P1, which is provided on a lower base 10 having the bolt hole 7, and which has the panel clamping portion 8 that clamps and fixes the outer edge 4 of one of the two solar panels 3 that are placed side by side on the mounting portion 5 of the solar panel mounting bracket A, and a second clamping bracket P2, which is provided on an upper base 11 that can be stacked on the lower base 10 and has the bolt hole 7 that communicates with the bolt hole 7 of the first clamping bracket P1 and through which the fixing bolt 6 passes, and which has the panel clamping portion 8 that clamps and fixes the outer edge 4 of the other of the two solar panels 3 that are placed side by side on the mounting portion 5 of the solar panel mounting bracket A, and further, when the upper base 11 of the second clamping bracket P2 is stacked on the lower base 10 of the first clamping bracket P1, the panel clamping portions 8 of the first clamping bracket P1 and the second clamping bracket P2 are arranged at different heights.

[0024] Therefore, by using two metal fittings (first clamping fitting P1 and second clamping fitting P2) of different heights for the panel clamping portion 8, the outer edge portions 4 of two solar panels 3 of different heights placed side by side on the mounting portion 5 of the solar panel mounting bracket A can be clamped and fixed.

[0025] In other words, the height (thickness) dimensions of solar panels 3 vary depending on the manufacturer, but by preparing multiple types of first clamping brackets P1 and second clamping brackets P2 that are compatible with each manufacturer and bringing them to the site, these can be used on-site to easily hold down and secure two solar panels 3 that are lined up at various different heights.

[0026] Furthermore, the first clamping fitting P1 of the present invention has a configuration equivalent to a so-called "end" clamping fitting (an existing clamping fitting that holds down and fixes only the outer edge 4 of one solar panel 3) that holds down and fixes the outer edge 4 of the solar panel 3 that is arranged at the very edge of the solar panels 3 lined up on the roof 1, and this existing "end" clamping fitting can be used as a substitute, and therefore the solar panel clamping fitting P of the present invention can be easily designed and realized by simply adding the second clamping fitting P2 to the first clamping fitting P1, which can be an off-the-shelf product. EXAMPLES

[0027] A specific embodiment of the present invention will now be described with reference to the drawings.

[0028] This embodiment relates to a solar panel fixing device comprising a solar panel mounting bracket A having a mounting portion 5 on the top of a bracket main body 2 which can be fixed onto a roof 1, on which two solar panels 3 can be placed with their outer edge portions 4 butted together, and having fixing bolts 6 provided in an upright position for fixing the two solar panels 3 placed on this mounting portion 5 to the bracket main body 2; and a solar panel pressing bracket P having bolt holes 7 through which the fixing bolts 6 pass, and a panel pressing portion 8 capable of pressing down the outer edge 4 of the solar panel 3 placed on the mounting portion 5 from above, and which is attached to the solar panel mounting bracket A by passing the fixing bolts 6 through the bolt holes 7 and screwing fixing nuts 9 onto the fixing bolts 6 which protrude upward from the bolt holes 7, and which is configured so that the outer edge portions 4 of the two solar panels 3 placed on the mounting portion 5 are pressed down and fixed by the panel pressing portion 8 when the fixing nuts 9 are tightened.

[0029] First, the solar panel mounting bracket A of this embodiment will be described. It is for mounting a folded-plate roof 1, and as shown in Figures 1 and 2, it has a pair of opposing clamping bodies 2 as the bracket main body 2 that can be mounted and fixed on the folded-plate roof 1 with its seam portion 2 as a mounting portion, and further, a mounting plate portion 14 on which the outer edge portion 4 of the solar panel 3 can be placed is provided on the upper portion of the opposing clamping bodies 2, and the upper surface of this mounting plate portion 14 is configured as the mounting portion 5, and the fixing bolt 6 for fixing the solar panel 3 placed on this mounting plate portion 14 (mounting portion 5) is provided in an upright state. Note that this solar panel mounting bracket A is not limited to being used for a folded-plate roof 1, and can be appropriately redesigned to be fixed to a vertical flat roof 1 or other roofs 1.

[0030] To explain the opposing clamping body 2 of this embodiment in detail, one opposing clamping body 2A is composed of a generally U-shaped plate body having a top plate portion (not shown) to which the above-mentioned mounting plate portion 14 and the fixing bolt 6 are attached, one side leg portion 15 suspended from one end of the top plate portion (the left side in Figs. 1 and 2), and a clamping portion 16 protruding from the lower end of the one side leg portion 15 in the same direction as the top plate portion, and the top plate portion, one side leg portion 15, and clamping portion 16 are all formed in a shape having a length along the slope direction of the roof 1, i.e., along the seam portion 13. Hereinafter, in this embodiment, the length direction of this opposing clamping body 2 will be defined as the front-rear direction of the solar panel mounting bracket A and will be explained.

[0031] The opposing clamping body 2A is formed, for example, from an extrusion of aluminum or an aluminum alloy (it is integrally formed by extrusion into a shape having a top plate portion, one leg portion 15, and clamping portion 16).

[0032] The other opposing clamping body 2B of the opposing clamping body 2 is composed of an approximately L-shaped plate-like body having an upright other-side leg 18 and a clamping portion 16 protruding from the lower end of the other-side leg 18 toward the one opposing clamping body 2A, and both the other-side leg 18 and the clamping portion 16 are formed in a shape having a length that follows the gable portion 2 of the roof 1. The upper part of the other-side leg 18 is hingedly connected to the other end of the top plate portion of the one opposing clamping body 2A, so that the other opposing clamping body 2B and the one opposing clamping body 2A are arranged in a left-right opposing state.

[0033] The other opposing clamping body 2B is made of, for example, an extrusion molded product of aluminum or an aluminum alloy (it is integrally molded by extrusion molding into a form having the other-side leg portion 18 and the clamping portion 16).

[0034] The fastening bolt 17 is disposed in an erected state between the left and right opposing clamping bodies 2A and 2B, and a fastening nut 19 is screwed onto the tip of the fastening bolt 17. When the fastening nut 19 screwed onto the fastening bolt 17 is tightened and rotated, the left and right opposing clamping bodies 2A and 2B approach each other (the other opposing clamping body 2B rotates and the clamping portion 16 of the other opposing clamping body 2B approaches the clamping portion 16 of one opposing clamping body 2A), and the left and right clamping portions 16 tighten and clamp the seam portion 13 from both outsides, so that the solar panel mounting bracket A is attached and fixed to the folded-plate roof 1 by the opposing clamping bodies 2A and 2B.

[0035] Next, the solar panel pressing metal fitting P of this embodiment will be described in detail. The solar panel pressing metal fitting P includes a lower base 10 having the bolt holes 7, a first pressing metal fitting P1 having the panel pressing portion 8 for pressing and fixing one of the outer edge portions 4 of the two solar panels 3 placed side by side on the mounting portion 5 of the solar panel mounting metal fitting A, and an upper base 11 capable of being stacked on the lower base 10, which has the bolt holes 7 communicating with the bolt holes 7 of the first pressing metal fitting P1 and through which the fixing bolts 6 pass, and a second pressing metal fitting P1 having the panel pressing portion 8 for pressing and fixing the other of the two solar panels 3 placed side by side on the mounting portion 5 of the solar panel mounting metal fitting A. The solar panel mounting bracket A is constructed of a second clamping bracket P2 having a panel pressing portion 8 that presses and fixes the outer edge portions 4 of the two solar panels 3 of different heights that are placed side by side on the mounting portion 5 of the solar panel mounting bracket A, and the first clamping bracket P1 and the second clamping bracket P2 are configured such that, when the upper base 11 of the second clamping bracket P2 is stacked on the lower base 10 of the first clamping bracket P1, the panel pressing portions 8 of the first clamping bracket P1 and the panel pressing portions 8 of the second clamping bracket P2, which are at different heights, press and fix the outer edge portions 4 of the two solar panels 3 of different heights that are placed side by side on the mounting portion 5 of the solar panel mounting bracket A. In the following, for the sake of convenience, in this embodiment, the bolt hole 7 of the first clamping fitting P1 will be referred to as the bolt hole 7A, the panel clamping portion 8 of the first clamping fitting P1 as the panel clamping portion 8A, the bolt hole 7 of the second clamping fitting P2 as the bolt hole 7B, and the panel clamping portion 8 of the second clamping fitting P2 as the panel clamping portion 8B.

[0036] More specifically, as shown in Figures 2 and 3, the first pressure fitting P1 has a rectangular plate-shaped lower base 10 having a length along the left-right direction perpendicular to the front-to-back direction (roof slope direction) of the solar panel mounting fitting A, and a horizontal rectangular foot plate portion 20 which contacts the mounting portion 5 is hung down from the front long side of the lower base 10 located below the roof slope, and a horizontal rectangular plate-shaped hanging piece 21 which has a shorter hanging length than the foot plate portion 20 is hung down from the rear long side of the lower base 10 located above the roof slope, and a horizontal rectangular plate-shaped first rising plate portion 22 is erected upward, and a horizontal rectangular plate-shaped first horizontal protruding plate portion 23 is further formed in a shape in which a horizontal rectangular plate-shaped first horizontal protruding plate portion 23 protrudes rearward (above the roof slope) from the upper end of the first rising plate portion 22. In the following description of this embodiment, the length direction of the lower base 10 is defined as the left-right direction of the first pressing fitting P1, and the direction perpendicular thereto is defined as the front-rear direction of the first pressing fitting P1.

[0037] A round hole serving as the bolt hole 7A is formed through the center of the lower base 10, and the hanging piece 21 and the rear side of the first rising plate portion 22 are configured as a first installation surface 24 that is installed along or close to the outer surface of the outer edge portion (aluminum frame portion) 4 of the solar panel 3, and the underside of the first horizontal protruding plate portion 23 is configured as the panel pressing portion 8A (the panel pressing portion 8A protrudes rearward from the rear end of the lower base 10 via the first rising plate portion 22), and this panel pressing portion 8A is configured to be able to press and fix the aluminum frame portion 4 of the solar panel 3, whose outer surface is installed along or close to the first installation surface 24, from above.

[0038] In addition, the first pressure fitting P1 is made of, for example, an extrusion molded product of aluminum or an aluminum alloy (it is integrally molded by extrusion into a form having a lower base 10, a leg plate portion 20, a hanging piece 21, a first rising plate portion 22, and a first horizontal protrusion portion 23).

[0039] In this embodiment, the first clamp metal fitting P1 is used to hold down and fix the solar panel 3A, which is the lower of the two solar panels 3 placed side by side on the placement portion 5 of the solar panel mounting bracket A. In addition, several types of the first clamp metal fitting P1 are prepared to accommodate solar panels 3 of different heights (panel thicknesses) depending on the manufacturer. Specifically, two types are prepared: one that is suitable for a solar panel 3A with a height of 40 mm (the distance from the placement portion 5 to the panel pressing portion 8A is set to about 40 mm when the leg plate portion 20 is placed on the placement portion 5), and one that is suitable for a solar panel 3A with a height of 35 mm (the distance from the placement portion 5 to the panel pressing portion 8A is set to about 35 mm when the leg plate portion 20 is placed on the placement portion 5).

[0040] 2 and 3, the second pressing fitting P2 has an upper base 11 of substantially the same shape (horizontal rectangular plate shape) as the lower base 10 that can be stacked on the lower base 10, with a second rising plate portion 25 standing up from the front long side disposed below the roof slope of this upper base 11, and a second horizontal protruding plate portion 26 protruding forward (above the roof slope) from the upper end of this second rising plate portion 25. Hereinafter, in this embodiment, the length direction of the upper base 11 is defined as the left-right direction of the second pressing fitting P2, and the direction perpendicular to this is defined as the front-rear direction of the second pressing fitting P2 for explanation.

[0041] Furthermore, a round hole is formed through the center of the upper base 11 as the bolt hole 7B, which communicates with the bolt hole 7A of the lower base 10 and through which the fixing bolt 6 passes, and further, the rear side of the second rising plate portion 25 is configured as a second installation surface 27 that is arranged along or close to the outer side surface of the outer edge portion (aluminum frame portion) 4 of the solar panel 3, and the lower surface of the second horizontal protruding plate portion 26 is configured as the panel pressing portion 8B (the panel pressing portion 8B protrudes forward via the second rising plate portion 25 from the front end portion of the upper base 11), and this panel pressing portion 8B is configured to press and fix the aluminum frame portion 4 of the solar panel 3, whose outer side is arranged along or close to the second installation surface 27 (and the front side of the foot plate portion 20), from above.

[0042] In addition, the second pressure fitting P2 is made of, for example, an extrusion molded product of aluminum or an aluminum alloy (it is integrally molded by extrusion molding into a form having an upper base body 11, a second rising plate portion 25, and a second horizontal protruding plate portion 26 (and the fulcrum protrusion portion 12 described below)).

[0043] In addition, this upper base 11 is configured so that it can be stacked on the lower base 10 of the first pressing fitting P1 while communicating the bolt holes 7A and 7B (see Figure 1) by arranging the panel pressing portion 8B of the second pressing fitting P2 in the opposite direction to the panel pressing portion 8A of the first pressing fitting P1 (by facing the panel pressing portion 8B of the second pressing fitting P2 forward (downward in the roof slope) with respect to the panel pressing portion 8A of the first pressing fitting P1 protruding rearward (upward in the roof slope direction)).

[0044] Therefore, when this upper base 11 is stacked on the lower base 10, the fixing bolt 6 of the solar panel mounting bracket A is passed through the communicating bolt holes 7A and 7B, and then a fixing nut 9 is screwed onto the fixing bolt 6 protruding upward from the upper base 11 via the bolt hole 7B, so that the panel pressing portion 8A of the first pressing bracket P1 protrudes rearward (upward of the roof slope) and the panel pressing portion 8B of the second pressing bracket P2 protrudes forward (downward of the roof slope), thereby allowing the panel pressing bracket P to be attached to the solar panel mounting bracket A. When the fixing nut 9 is further tightened and rotated, the upper base 11 is pressed against the lower base 10 and the first and second clamping fittings P1 and P2 move in the direction in which the leg plate portion 20 is pressed against the mounting portion 5, so that the panel clamping portion 8A of the first clamping fitting P1 and the panel clamping portion 8B of the second clamping fitting P2 press and fix the outer edge portions 4 of the two solar panels 3 of different heights that are placed side by side on the mounting portion 5 of the solar panel mounting bracket A with their outer edge portions (aluminum frame portions) 4 butted together in the roof slope direction.

[0045] In this embodiment, the second pressing metal fitting P2 is used to press and fix the taller solar panel 3B of the two solar panels 3 placed side by side on the mounting portion 5 of the solar panel mounting metal fitting A. Furthermore, several types of second pressing metal fitting P2 configured in this manner are prepared by different manufacturers to accommodate solar panels 3 of different heights (panel thicknesses). Specifically, two types are available: one that corresponds to a solar panel 3B that is 45 mm in height (one that is set so that when the upper base 11 of the second clamping fitting P2 is loaded on the lower base 10 of the first clamping fitting P1 placed on the loading portion 5, the distance from the loading portion 5 to the panel clamping portion 8B is approximately 45 mm), and one that corresponds to a solar panel 3B that is 40 mm in height (one that is set so that when the upper base 11 of the second clamping fitting P2 is loaded on the lower base 10 of the first clamping fitting P1 placed on the loading portion 5, the distance from the loading portion 5 to the panel clamping portion 8B is approximately 40 mm).

[0046] That is, in this embodiment, by combining two types of first clamping metal fittings P1 and two types of second clamping metal fittings P2, three installation modes can be selected: an installation mode in which the first clamping metal fitting P1 holds and fixes a solar panel 3A with a height of 35 mm, and the second clamping metal fitting P2 holds and fixes a solar panel 3B with a height of 40 mm; an installation mode in which the first clamping metal fitting P1 holds and fixes a solar panel 3A with a height of 35 mm, and the second clamping metal fitting P2 holds and fixes a solar panel 3B with a height of 45 mm (FIG. 3); and an installation mode in which the first clamping metal fitting P1 holds and fixes a solar panel 3A with a height of 40 mm, and the second clamping metal fitting P2 holds and fixes a solar panel 3B with a height of 45 mm. Therefore, by bringing a plurality of the two types of first clamping metal fittings P1 and two types of second clamping metal fittings P2 to the site, it is possible to easily handle the installation of the solar panel 3 in the above three modes at the site.

[0047] In addition, in this embodiment, the second clamping fitting P2 has a fulcrum protrusion 12 that protrudes downwardly (integrally molded) on the rear underside of its upper base 11 (the underside of the end opposite the panel clamping portion 8B) and contacts the upper surface of the lower base 10 of the first clamping fitting P1.

[0048] To explain this fulcrum convex portion 12 in more detail, it has a convex stripe shape that extends across the entire left-right width of the upper base 11, and its underside is formed into a curved surface that convex downwards when viewed from the side, as shown in Figure 3.When this upper base 11 is stacked on the lower base 10 of the first pressing fitting P1 and the fixing nut 9 is tightened, the upper base 11 tilts around the fulcrum convex portion 12 that contacts the lower base 10 as a fulcrum, and the panel pressing portion 8B of the second pressing fitting P2 is guided downwardly to move downward, and the outer edge portion 4 of the solar panel 3B is firmly pressed down and fixed by this moving panel pressing portion 8B. At this time, the fulcrum convex portion 12 comes into contact with the vicinity of the first rising plate portion 22 of the lower base 10 of the first clamping fitting P1, so that the tightening load of the fixing nut 9 acts strongly on the first rising plate portion 22 side of the first clamping fitting P1, and as a result (because the hanging length of the hanging portion 21 is shorter than the leg plate portion 20 and is not in contact with the mounting portion 5), the panel clamping portion 8A is guided to move downward with the lower end of the leg plate portion 20 as a fulcrum, and the outer edge portion 4 of the solar panel 3A is also firmly pressed down and fixed by this descending panel clamping portion 8A.

[0049] Incidentally, the present invention is not limited to the present embodiment, and the specific configuration of each component can be designed as appropriate. [Explanation of symbols]
