Description

  The present invention relates to a solar cell module and a solar cell system having a frameless structure including a solar cell panel having a laminated glass structure in which solar cells are interposed between a light-receiving surface glass and a back glass.

  In recent years, in order to reduce weight, a frameless structure solar cell module in which a frame for holding the periphery of the solar cell panel is eliminated has been provided, and a solar cell module having a laminated glass structure solar cell panel is also frameless. A structure is provided. A recent solar cell system is constructed by installing this frameless solar cell module on a base fixed to a roof or a foundation in a site.

  However, the frameless structure of the solar cell module has a problem that the edge of the solar cell panel is exposed, and the edge of the solar cell panel, especially the corner, is damaged by a slight impact during construction. was there.

  In order to solve this problem, a solar cell module having a frameless structure in which a corner member made of an insulating member is attached to a corner portion of a solar cell panel has already been proposed (for example, see Patent Document 1).

  As shown in FIG. 42, this solar cell module has a structure in which a corner member 107 formed in a square shape in plan view is fitted to a corner portion 106 of a module body (solar cell panel) 105. That is, a square cut portion 108 is formed at one corner of the square corner member 107, and the cut portion 108 is fitted to the corner portion 106 of the module body 105.

JP 2004-22761 A

  However, when the corner member 107 has a square shape, it is necessary to increase the overall shape in order to protect the corner portion 106 of the module body 105 over a wide range. However, when the overall shape is increased, the cut depth of the cut portion 108 is increased, and as a result, the corner member 107 covers the power generation region (shown by hatching) 105a of the module main body 105. Therefore, when the power generation efficiency is taken into consideration, the cut portion 108 cannot be formed so deeply. That is, the shape of the corner member 107 itself cannot be made too large. As a result, the corner portion 106 of the module body 105 that can be covered with the corner member 107 has a very small area, and it cannot be said that the corner portion 106 is sufficiently protected from impact over a wide range.

  If the shape of the corner member 107 is increased in order to protect the corner portion 106 of the module body 105 over a wide range, the portion that protrudes from the module body 105 becomes larger, and this protrusion protrudes when it is juxtaposed on the frame. The corner member 107 is in the way, causing a problem that adjacent solar cell modules cannot be closely arranged. That is, a gap is created between the solar cell modules by the protruding corner member 107, which causes a problem that power generation efficiency with respect to the installation area decreases.

  In the first place, the main purpose of the solar cell module described in Patent Document 1 is to prevent moisture from entering from the corner portion 106 of the module body 105, thereby ensuring insulation, and preventing damage is not the main purpose. However, the shape and dimensions of the corner member 107 are not sufficiently studied for preventing damage.

  Moreover, since it receives wind pressure, snow pressure, etc. after construction, it is necessary to further improve the strength, but the prior patent document 1 does not consider the strength after construction. Prior Patent Document 1 has a structure in which a protrusion is provided on the back surface of the corner member 107, but this protrusion is caught by a member located at least in a direction perpendicular to the flow direction of the roof to prevent the protrusion. This structure is not intended to improve strength.

  The present invention was devised to solve such problems, and its purpose is to sufficiently protect the corner portion of the solar cell panel from a wide range of impacts, and to stably install the corner portion when installed on the gantry. An object of the present invention is to provide a solar cell module and a solar cell system that can be used.

  In order to solve the above problems, a solar cell module of the present invention is a solar cell module including a solar cell panel having a laminated glass structure in which solar cells are interposed between a light-receiving surface glass and a back glass, A buffer member is provided at a corner portion of the solar cell panel, and the buffer member includes a surface piece attached to an edge surface of the solar cell panel and a vertical piece attached to an edge side surface of the solar cell panel. It is characterized by consisting of.

  Since the corner portion of the frameless solar cell panel is vulnerable to impact, the corner portion may be damaged during the construction of the solar cell panel. Therefore, by providing a buffer member at this corner portion, breakage during construction can be prevented or reduced. In this case, the buffer member is formed by a surface piece attached to the edge surface of the solar cell panel and a vertical piece attached to the side surface of the edge of the solar cell panel, so that The shock received from the direction and the lateral direction can be absorbed by the buffer member.

  In the solar cell module of the present invention, a long support member is disposed and fixed along the longitudinal direction of the solar cell panel on the surface of the back glass, and the support member is a long main plate. And side plates bent downward from both sides along the longitudinal direction of the main plate, and part of both end portions in the longitudinal direction of the side plate are notched in an L shape, and the surface of the solar cell panel To the cutout portion parallel to the solar cell panel, the height is approximately the same as the length of the vertical piece of the buffer member. Thus, by forming the length of the vertical piece of the buffer member substantially the same as the height reaching from the surface of the solar cell panel to the cutout portion of the support member, the cutout portion of the support member can be made, for example, a frame When installed so as to fit on the crosspiece, the vertical piece of the buffer member comes into contact with the crosspiece of the gantry so that the corner portion of the solar cell panel can be stably installed on the gantry.

  In the solar cell module of the present invention, the buffer member is configured to be bonded and fixed to the edge portion of the solar cell panel by an adhesive member.

  The buffer member can be securely fixed to the solar cell panel by bonding and fixing the buffer member with an adhesive member (such as an adhesive tape or a resin adhesive).

  Moreover, in the solar cell module of this invention, the said buffer member is good also as a structure further provided with the back piece attached to the edge part back surface of the said solar cell panel.

  The buffer member, a surface piece attached to the edge surface of the solar cell panel (specifically, the edge surface of the light-receiving surface glass), a vertical piece attached to the edge side surface of the solar cell panel, By forming a U-shaped cross-section with a back piece attached to the back of the edge of the solar cell panel (specifically, the edge of the back glass), the corner of the solar cell panel is The shock received from the three directions of the direction, the lateral direction, and the downward direction can be absorbed by the buffer member.

  In the solar cell module of the present invention, a long support member is disposed and fixed along the longitudinal direction of the solar cell panel on the surface of the back glass, and the support member is a long main plate. And a side plate bent downward from both sides along the longitudinal direction of the main plate, part of both end portions in the longitudinal direction of the side plate are notched in an L shape, and the back surface of the solar cell panel To the cutout portion parallel to the solar cell panel, the height is approximately the same as the thickness of the back piece of the buffer member. In this way, the thickness of the back piece of the buffer member is formed to be substantially the same as the height reaching from the back surface of the solar cell panel to the cutout portion of the support member. When installed so as to fit together, the corners of the solar cell panel can be stably installed on the frame of the frame because the back piece of the buffer member comes into contact with the frame of the frame.

  Moreover, in the solar cell module of this invention, the said buffer member is set as the structure fixed to the edge part of the said solar cell panel by the adhesion fixation and / or fitting fixation by the adhesive member.

  The buffer member is bonded and fixed with an adhesive member (adhesive tape, resin adhesive, etc.), and / or the buffer member is fitted and fixed so that the edge of the solar cell panel is sandwiched from above and below by the front and back pieces. It can be reliably and easily fixed to the solar cell panel.

  Moreover, in the solar cell module of this invention, the said buffer member is formed in planar view L shape.

  Thus, by arranging the buffer member along two adjacent edges of the corner portion of the solar cell panel, the corner portion can be protected over a wide range, and the buffer member can be more stably disposed. .

  In the solar cell module of the present invention, a long support member is arranged and fixed along the longitudinal direction of the solar cell panel on the surface of the back glass, and the buffer member is in contact with the support member. It is good also as a structure provided to the position to do.

  By providing the buffer member up to a position in contact with the support member, the buffer member can be more stably disposed.

  Moreover, in the solar cell module of this invention, the said buffer member is set as the structure provided except the electric power generation area | region of the said solar cell panel.

  By providing the buffer member at the edge of the light-receiving surface glass excluding the power generation region, it is possible to prevent a decrease in power generation efficiency.

  Moreover, the solar cell system of the present invention is a solar cell system including a crosspiece that supports the solar cell module having the above-described configuration, and the cutout portion of the long support member is fitted to the crosspiece. When the solar cell module is installed, at least one side of the solar cell module is parallel to the crosspiece, and the vertical piece or the back piece of the buffer member is in contact with the crosspiece. In this way, when the vertical piece or the back piece of the buffer member is provided so as to contact the frame of the gantry, when the notch portion of the support member is fitted on the frame of the gantry, the buffer member When the vertical piece or the back piece of the solar cell comes into contact with the frame of the gantry, the corner portion of the solar cell panel can be stably installed on the frame of the gantry.

  Since this invention was comprised as mentioned above, it can prevent or reduce the damage of the corner part of a solar cell panel by the impact at the time of construction, etc. In this case, the buffer member is formed of a surface piece attached to the edge surface of the solar cell panel (the edge surface of the light receiving surface glass) and a vertical piece attached to the edge side surface of the solar cell panel. Thus, the shock received from the upward or lateral direction of the solar cell panel during construction can be absorbed by this buffer member. Moreover, when the solar cell module is installed on the frame of the gantry by causing the vertical piece of the buffer member to protrude from the edge side surface of the solar cell panel toward the back surface, the vertical piece of the buffer member comes into contact with the frame of the gantry. Thus, the corner portion of the solar cell panel can be stably installed on the frame of the mount.

  Moreover, the buffer member is attached to the edge surface of the solar cell panel (the edge surface of the light-receiving surface glass), a vertical piece attached to the edge side surface of the solar cell panel, and the solar cell panel This shock absorbing member absorbs the impact received from the upper, lateral, and lower sides of the solar cell panel during construction by forming with the back piece attached to the back of the edge of the glass (the edge surface of the back glass) can do. In addition, when the solar cell module is installed on the frame of the gantry, the back piece of the buffer member abuts on the frame of the gantry, so that the corner portion of the solar cell panel can be stably installed on the frame of the gantry, And the intensity | strength after construction can be improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing the overall configuration of a solar cell system in a state where a plurality of solar cell modules 16 according to the present invention are installed on a gantry 10.

  The solar cell system of the present embodiment has a structure that can be used as, for example, a power plant, and the gantry 10 is roughly constituted by a concrete foundation 11, a base beam 12, an arm 13, a vertical beam 14, and a horizontal beam 15. Has been.

  That is, a plurality of concrete foundations 11 are laid on the ground at equal intervals, and base bars 12 are arranged in parallel at equal intervals on the upper surface 111 of each concrete foundation 11 and fixed. Then, the arm 13 is connected to the rear end portion 121 of each base crosspiece 12 so as to stand upright, and the vertical crosspiece 14 is bridged obliquely between the front end portion 122 of each base crosspiece 12 and the upper end portion of each arm 13. Further, three horizontal bars 15 are arranged so as to be orthogonal to the vertical bars 14, and the horizontal bars 15 are arranged side by side on the vertical bars 14. In other words, the horizontal rails 14 are arranged at different heights along the inclination of the vertical rails 14, and the longitudinal ends of the solar cell module 16 are bridged between the adjacent horizontal rails 15. The solar cell module 16 is installed in an inclined state. And it is the structure which supports and fixes the both ends of the solar cell module 16 by attaching the guide support tool 17 (refer FIG. 25 etc.) mentioned later to the predetermined | prescribed location on each crosspiece 15. FIG.

  In the solar cell system having such a configuration, a plurality of solar cell modules 16 are arranged in a horizontal row between the lower horizontal beam 15 and the central horizontal beam 15, and the central horizontal beam 15 and the upper horizontal beam 15 are installed. A plurality of solar cell modules 16 are arranged in a horizontal row between the horizontal rails 15. In other words, a plurality of solar cell modules 16 are arranged in two rows on the top and bottom of the three horizontal rails 15. Also, three solar cell modules 16 are arranged side by side between two vertical bars 14 adjacent to each other on the left and right.

  In the following description, a direction in which the concrete foundations 11 are arranged in FIG. 1 is an X direction (left-right direction), and a direction orthogonal to the X direction is a Y direction (front-rear direction).

  2 to 4 show the basic configuration of the solar cell module 16 according to the present embodiment (that is, the configuration before providing the buffer member, which is a feature of the present invention), and FIG. 2 is viewed from the light receiving surface side. 3 is a perspective view seen from the back side opposite to the light receiving surface, and FIG. 4 is an exploded perspective view seen from the back side.

  The solar cell module 16 of the present embodiment includes a solar cell panel 18 and two support members 19 that also serve as mounting brackets to the gantry 10.

  As shown in FIG. 4, the solar battery panel 18 is a solar battery panel having a laminated glass structure in which solar battery cells 18 a that photoelectrically convert sunlight are interposed between a light-receiving surface glass 18 b and a back glass 18 c. A long support member 19 formed in a shape that allows the solar cell panel 18 to be attached to the gantry 10 is disposed and fixed along the longitudinal direction of the solar cell panel 16 on the surface of the back glass 18c. Two support members 19 are arranged in parallel at a symmetric position with respect to a center line passing through the center in the short direction, with a predetermined interval in the short direction of the solar cell panel 16. Moreover, the arrangement position is arrange | positioned in the position put only a fixed distance inward from each edge | side of a longitudinal direction. Specifically, the solar cell panel 18 has a rectangular shape in a plan view having a longitudinal direction of about 1400 mm and a short side direction of about 1000 mm, and each support member 19 is about 200 mm inward from each side in the longitudinal direction (however, , Which is not limited to 200 mm). Thus, by arranging two support members 19 in the short direction of the solar cell panel 18, when the solar cell module 16 is installed on the gantry 10, the short direction (left and right direction) is stable and stable. Thus, the solar cell module 16 can be installed on the gantry 10. Further, by disposing the support member 19 at a position about 200 mm inward from the longitudinal edge of the solar cell panel 18, the weight distribution of the solar cell panel 18 on the support member 19 is dispersed in a well-balanced manner. be able to.

  The support member 19 is bonded and fixed to the surface of the back glass 18c of the solar cell panel 18 by a double-sided tape 20 having an adhesive layer on both sides of the cushion member. An acrylic pressure-sensitive adhesive layer can be used as the pressure-sensitive adhesive layer. In addition, as the cushion member, polyolefin, acrylic rubber, or the like can be used. Thus, by using the double-sided tape 20 having the adhesive layer on both sides of the cushion member for fixing the back glass 18c and the support member 19 of the solar cell panel 18, for example, after being attached to the gantry 10, the influence of the surrounding environment Even if the support member 19 and the solar cell panel 18 are thermally contracted or expanded due to (temperature change), due to the difference in thermal expansion coefficient between the support member 19 and the solar cell panel 18 (specifically, the back glass 18c) at that time. Stress can be relaxed. That is, it is possible to reduce the load stress on the solar cell panel 18 and prevent damage such as cracks.

  In addition, the code | symbol 41 shown in FIG.3 and FIG.4 is a terminal box for pulling out the output lead wire of the photovoltaic cell 18a from the opening part 18c1 of the back surface glass 18c, and electrically connecting it.

  Next, the shape of the support member 19 will be described.

  5 is a perspective view showing the support member 19, FIGS. 6A, 6B, and 6C are a front view, an enlarged side view, a side view, and a sectional view showing the end of the holding member 19, FIG. FIG. 4 is an enlarged perspective view showing the vicinity of an end portion of a support member 19 in the solar cell module 16.

  A support member 19 shown in FIGS. 5 and 6A, 6B, and 6C includes a long main plate 19a and a side plate 19b bent downward from both side portions along the longitudinal direction of the main plate 19a. The bottom plate 19c bent inward from the lower end of each side plate 19b, the inner plate 19d bent upward from the opposite inner end of each bottom plate 19c, and the longitudinal ends of the main plate 19a are bent upward. L-shaped engaging portion 19e, and the cross-sectional shape thereof is substantially the shape of a lip groove steel. That is, the support member 19 is formed in a substantially lip groove steel shape, and the inner side plate 19d is formed by bending the front end side of the lip portion (bottom plate 19c) to the inner package (main plate 19a side), thereby further reinforcing the strength. ing. Thereby, when the supporting member 19 is attached to the gantry 10 and the entire solar cell panel 18 is supported by the supporting member 19, the supporting member 19 can be maintained at a sufficient strength against the load of the solar cell panel 18, It can withstand long-term use.

  As shown in FIG. 7, the support member 19 has both end portions in the longitudinal direction of the main plate 19 a protruding from both end portions in the longitudinal direction of the solar cell panel 18. The engaged portion 19e is formed. The engaging portion 19e has an L shape that can be engaged with the guide support 17 of the gantry 10.

  Thus, by providing the engaging portion 19e which is the end portion of the support member 19 so as to protrude from the end portion of the solar cell panel 18, when the solar cell module 16 is installed on the mount 10, the support member 19 is engaged. Visual alignment between the joint portion 19e and the mounting position on the gantry 10 side becomes easy. Thereby, workability | operativity at the time of installing the solar cell module 16 in the mount frame 10 can be improved. Further, by forming the protruding engaging portion 19e of the support member 19 into a shape that engages with the mounting bracket on the mount 10 side when the support member 19 is installed on the mount 10, the number of mounting brackets when mounted on the mount 10 is reduced. be able to. Therefore, the number of mounting steps can be reduced, and the mounting work can be facilitated.

  Further, the support member 19 is formed with a contact portion 19f that contacts the corner portion of the horizontal rail 15 of the gantry 10 by cutting out a part of each longitudinal end portion of each side plate 19b into an L shape. Yes. In the support member 19 shown in FIGS. 5 and 6A, 6B, and 6C, the contact portion 19f extends from the lower end edge to the upper end edge in the vicinity of both ends in the longitudinal direction of each side plate 19b. A notch is formed by bending the notch piece 19g on the end side of the side plate 19b separated by the notch until it is inwardly parallel to the main piece 19a (see FIGS. 6A and 6B). )can do. In addition, about the length of the cut piece 19g, what is necessary is just to cut | disconnect with an appropriate length so that the front-end | tip parts may not hit when it bends.

  8A and 8B show other shapes of the support member. The support member 19A shown in FIGS. 8A and 8B includes a long main plate 19a, side plates 19b bent downward from both sides along the longitudinal direction of the main plate 19a, and both ends of the main plate 19a in the longitudinal direction. Engaging portions 19e bent upward at the respective portions, and the cross-sectional shape thereof is a substantially hat type (that is, the shape of a substantially light groove steel). Thus, even if the support member 19 is formed in a substantially light-grooved steel shape, when the support member 19A is attached to the gantry 10 and the entire solar cell panel 18 is supported by the support member 19A, the solar cell panel 18 The supporting member 19A can be kept at a sufficient strength against the load of.

  The support members 19 and 19A having such shapes may be manufactured by cutting and bending a steel plate, or may be manufactured by extruding an aluminum material.

  However, in the following description, the case where the support member 19 having the cross-sectional shape shown in FIGS. 5 to 7 is used will be described.

  FIG. 9 is a partially enlarged sectional view of the solar cell panel.

  As shown in FIG. 9, the solar battery panel 18 has a laminated glass structure in which solar battery cells 18 a that photoelectrically convert sunlight are interposed between a light-receiving surface glass 18 b and a back glass 18 c. The plate thickness t1 of 18b is formed thinner than the plate thickness t2 of the back glass 18c (t1 <t2). That is, in this embodiment, the support member 19 is disposed on the back glass 18c. The support member 19 plays a role of reinforcing the back glass 18c in addition to the role as a fixture to the gantry 10. Therefore, even if the thickness of the light receiving surface glass 18b is made thinner than the thickness of the back glass 18c (more specifically, even if the light receiving surface glass 18b is made thinner than the conventional thickness), the strength as the solar cell panel 18 is supported. Since it is reinforced by the member 19, there is no problem. That is, according to this embodiment, it is possible to reduce the weight of the entire solar cell module 16 by thinning the light-receiving surface glass 18b while maintaining sufficient strength.

  In addition, by making the light-receiving surface glass thinner, it is possible to secure the same light transmittance as white glass with high light transmittance, so it is possible to use blue glass with a low cost as the light-receiving surface glass, and manufacture of solar cell modules There is also an advantage that the cost can be reduced.

  Next, the gantry 10 according to the present embodiment will be described.

  The gantry 10 according to the present embodiment includes the concrete foundation 11, the base beam 12, the arm 13, the vertical beam 14, the horizontal beam 15, and the guide support 17 shown in FIG. 1, and further the support members shown in FIGS. 2 to 8. 19 is also used as a component of the gantry.

  Next, the concrete foundation 11, the base beam 12, the arm 13, the vertical beam 14, the horizontal beam 15 and the like constituting the gantry 10 will be described.

  Each concrete foundation 11 is formed by forming a mold on the ground and pouring concrete into the mold. Each concrete foundation 11 is arrange | positioned at equal intervals, and those upper surfaces 111 are horizontal and the same height and are flush | level.

  The upper surface 111 of these concrete foundations 11 is used as a horizontal foundation surface, and the base bars 12 are fixed on the foundation surface at equal intervals and in parallel. Further, the base bars 12, the arms 13, and the vertical bars 14 are fixed. , And the horizontal rails 15 are connected to assemble the gantry 10. Of course, instead of the plurality of concrete foundations 11, it is also possible to apply foundations of other structures such as a solid foundation in which concrete is uniformly poured into the entire installation area of the gantry.

  FIG. 10 is a perspective view showing the base bar 12. As shown in FIG. 10, the base bar 12 has a long main plate 12b, a pair of side plates 12a bent on both sides of the main plate 12b, and a flange 12c bent outward on one side of each side plate 12a. The cross-sectional shape is generally a hat shape. Respective elongated holes 12d are formed in the vicinity of both ends of the main plate 12b of the base bar 12, and respective perforations 12e are formed at both ends of each side plate 12a.

The guide support 17 is disposed on the main plate 15 b of the horizontal beam 15 by projecting onto the main plate 15 b of the horizontal beam 15 and inserting the heads 33 c 1 of the support pieces 33 c into the slits 17 h of the guide support 17. Then, the perforations 17g of the guide support 17 are overlapped with the screw holes 33d of the mounting bracket 33 through the T-shaped holes 15d of the horizontal rail 15, and the bolts 34 are perforated 17g of the guide support 17 and the T-shaped holes of the horizontal rail 15. It is screwed into the screw hole 33d of the mounting bracket 33 through 15d and tightened. As a result, the guide support 17 is fixed on the main plate 15b of the cross rail 15.

  The concrete foundation 11, the base beam 12, the arm 13, the vertical beam 14, the horizontal beam 15, and the guide support 17 are assembled as described above, and the main structure of the gantry 10 as shown in FIG. 28 is formed. In FIG. 28, each concrete foundation 11 is laid, and a triangular structure including a base beam 12, an arm 13, and a vertical beam 14 is formed on each concrete foundation 11, and three horizontal beams 15 are formed on each vertical beam 14. A plurality of guide supports 17 are fixed on the horizontal rails 15 at intervals.

  Next, support of the solar cell module 16 by the guide support 17 on the horizontal rail 15 will be described.

  As is apparent from FIGS. 25 and 26, the fitting grooves 17d on both sides of the guide support 17 are arranged in parallel with the horizontal rails 15, and the hooking portions 17e (see FIG. 21) of the fitting grooves 17d A gap is formed between the main plate 15 b of the crosspiece 15. Then, the engaging portion 19e of the support member 19 of the solar cell module 16 enters the fitting groove 17d through the gap between the hooking portion 17e of the fitting groove 17d and the main plate 15b of the horizontal rail 15, and the engagement of the supporting member 19 is performed. The portion 19e is fitted (engaged) in the fitting groove 17d.

  Further, the side plate 19b of the support member 19 contacts the stopper 17f of the guide support 17, and the contact portion 19f of the support member 19 contacts the main plate 15b of the horizontal beam 15 and the side plate 15a (the corner of the horizontal beam 15). Yes.

  As described above, the engagement portion 19e of the support member 19 is fitted into the fitting groove 17d of the guide support 17 so that the end portion along the longitudinal direction of the support member 19 is supported. The end portion is supported on the main plate 15 b of the horizontal rail 15. At this time, the side plate 19b of the support member 19 comes into contact with the stopper 17f of the guide support 17 and the contact portion 19f of the support member 19 comes into contact with the corner portion of the horizontal rail 15 so that the solar cell module 16 is positioned.

  That is, the contact portion 19f of the side plate 19b of the support member 19 is in contact with the two sides of the main plate 15a and the side plate 15b at the corner of the crosspiece 15 so that the longitudinal direction of the support member 19 (in FIG. Movement in the Y direction) can be reliably controlled, and the engagement portion 19e of the support member 19 is fitted in the fitting groove 17d of the guide support 17 so that the movement in the direction perpendicular to the installation surface of the gantry 10 can be achieved. The movement can be restricted.

  Further, the side plate 19b of the support member 19 abuts against the stopper 17f of the guide support 17 so that the support member 19 is prevented from sliding (sliding in the X direction in FIG. 1), and the solar cell module 16 is also prevented from sliding. .

  As shown in FIGS. 1 and 28, the position of each guide support 17 on the crosspiece 15 is common in each of the crosspieces 15, and the first guide supporter on each crosspiece 15. 17 are arranged on a straight line in the Y direction, the second guide support 17 on each horizontal beam 15 is arranged on a straight line in the Y direction, and thereafter the nth guide support 17 on each horizontal beam 15 is similarly arranged. Line up on a straight line in the Y direction. In addition, the pitch of the first and second guide supports 17 is set to be the same as the pitch of the two support members 19 of the solar cell module 16, and the pitch of the third and fourth guide supports 17 is the solar cell module. 16 is set to be the same as the pitch of the two support members 19, and similarly, the pitch of the odd-numbered and even-numbered guide supports 17 is set to be the same as the pitch of the two support members 19 of the solar cell module 16. Has been. That is, each guide support 17 is provided on each of the horizontal rails 15 so that the end portions of the two support members 19 of the solar cell module 16 can be supported by the odd-numbered and even-numbered guide support 17. It is positioned.

  Further, the pitches of the second and third guide supports 17 are arranged so that the pitches of the fourth and fifth guide supports 17, that is, the odd and even guide supports 17 are adjacent to each other. The pitch of the support members 19 of the two solar cell modules 16 is set to be approximately the same or slightly wider. Thereby, it is possible to arrange the solar cell modules 16 side by side with almost no gap between the two adjacent solar cell modules 16.

  Here, in order to insert the engaging portion 19e of the support member 19 into the fitting groove 17d of the guide support member 17, as shown in FIGS. 29 and 30, the protruding end portion of the support member 19 of the solar cell module 16 is provided. The protruding end of the support member 19 of the solar cell module 16 is placed on the main plate 15b of the horizontal rail 15 in a state where it is shifted laterally (in the X direction) from the guide support 17 of the horizontal rail 15. Then, as shown in FIG. 26, the contact portion 19 f of the support member 19 is brought into contact with the main plate 15 b and the side plate 15 a (corner portion of the horizontal beam 15) of the horizontal beam 15. By this contact, the engaging portion 19e of the support member 19 is positioned with respect to the corner portion of the horizontal rail 15, and when viewed from the X direction, the engaging portion 19e of the support member 19 is fitted into the fitting groove of the guide support member 17. It overlaps 17d.

  In this state, as shown in FIGS. 29 and 30, the solar cell module 16 is slid in the X direction (right direction in the figure), and the contact portion 19f of the support member 19 is moved to the main plate 15b and the side plate 15a of the cross rail 15. , The engagement portion 19e of the support member 19 enters from the opened end of the fitting groove 17d of the guide support device 17, and the engagement portion 19e of the support member 19 is fitted to the guide support device 17. It fits in the mating groove 17d. When the solar cell module 16 is further slid in the X direction (rightward in the figure), the side plate 19b of the support member 19 comes into contact with a stopper 17f provided at the other end of the fitting groove 17d of the guide support 17. .

  Thereby, the edge part of the solar cell module 16 is supported on the main plate 15b of the horizontal rail 15. Further, the side plate 19 b of the support member 19 contacts the stopper 17 f of the guide support 17, and the contact portion 19 f of the support member 19 contacts the corner portion of the horizontal rail 15, so that the solar cell module 16 is positioned. Further, the contact of the side plate 19b of the support member 19 with the stopper 17f of the guide support 17 prevents the support member 19 from sliding (sliding in the descending order of the arrangement of the solar cell modules 16). Sliding in the descending direction is also prevented.

  In the lower horizontal beam 15 and the central horizontal beam 15 shown in FIG. 1, the first and second guides of each horizontal beam 15 are connected to both ends of each support member 19 of the rightmost first solar cell module 16. The both ends of each support member 19 of the solar cell module 16 are placed on each horizontal rail 15 by shifting from the support 17. At this time, due to the own weight of the solar cell module 16, the abutting portions 19 f of the support members 19 in the downwardly inclined direction of the solar cell module 16 abut on the corners of the lower horizontal rail 15. By this contact, when viewed from the X direction, the engaging portion 19e in the downwardly inclined direction of each support member 19 overlaps the fitting groove 17d of the guide support 17 of the lower horizontal rail 15.

  In addition, the interval between the horizontal beams 15 is set in advance so that the distance between the fitting grooves 17d of the guide support 17 on each horizontal beam 15 is the same as the distance between the engaging portions 19e at both ends of the support member 19. It has been adjusted. This adjustment can be performed when the horizontal rail 15 is fixed by the mounting bracket 31 as described above. In this case, when the contact portion 19f of each support member 19 in the downward inclination direction of the solar cell module 16 contacts the corner portion of the lower horizontal rail 15, the inclination of each support member 19 when viewed from the X direction. The engaging portion 19e at the other end in the upward direction also overlaps with the fitting groove 17d of the guide support 17 of the central cross rail 15.

  In this state, as shown in FIGS. 29 and 30, the solar cell module 16 is slid in the X direction, and the engaging portions 19 e at both ends of each support member 19 are fitted to the guide support 17 of each horizontal rail 15. The both ends of the solar cell module 16 are supported in a state of being laid over the horizontal rails 15 by being inserted into the grooves 17d, fitted and brought into contact with the stoppers 17f.

  When the solar cell module 16 is slid, as shown in FIG. 26, the contact portions 19 f of the support members 19 in the downward direction of the solar cell module 16 are in contact with the corners of the lower horizontal rail 15. As a result, the downward and horizontal movements of the contact portions 19f of the support members 19 are restricted, and the solar cell module 16 does not slide down due to its own weight, ensuring work safety. .

  As is clear from FIG. 26, since play is set between the engaging portion 19e of the support member 19 and the fitting groove 17d of the guide support 17, the fitting groove 17d of the guide support 17 is provided. A slight displacement of the engaging portion 19e of the support member 19 with respect to the position does not become a problem. Also, by setting this play, even if the length of the support member 19 is changed due to thermal expansion or contraction, this change can be allowed.

  Subsequently, in the same procedure, the engaging portions 19e at both ends of each support member 19 of the second solar cell module 16 are inserted and fitted into the fitting grooves 17d of the guide support 17 of each horizontal rail 15, The side plate 19b of the support member 19 is brought into contact with the stopper 17f, and both end portions of the solar cell module 16 are supported on the horizontal rails 15. In the same manner, the third, fourth,... Solar cell modules 16 are supported across the horizontal rails 15, and the lower first row is interposed between the lower horizontal rail 15 and the central horizontal rail 15. The solar cell modules 16 are arranged side by side. Similarly, the solar cell modules 16 in the upper first row are arranged in parallel between the central horizontal beam 15 and the upper horizontal beam 15.

  In addition, about the last order solar cell module 16, as shown in FIG. 31, after removing the last order guide support tool 17 on the horizontal rail 15 and reversing the left and right of the guide support tool 17, The guide support 17 is fixed again on the horizontal rail 15, and the engaging portion 19 e of the support member 19 is fitted into the fitting groove 17 d of the guide support 17 to support the end of the support member 19. Also at this time, the side plate 19b of the support member 19 is brought into contact with the stopper 17f of the guide support 17 to prevent the support member 19 from sliding. However, since the left and right of the guide support 17 are reversed, this is prevented. The sliding direction becomes the ascending order of the arrangement of the solar cell modules 16. Thereby, the slide to the ascending order of the solar cell module 16 of the last order is blocked | prevented. In each of the horizontal rails 15, the right and left of the last order guide support 17 are reversed and fixed, and the last order solar cell module 16 is prevented from sliding in the ascending order.

  Thus, when the last order solar cell module 16 is prevented from sliding in the ascending order, the solar cell modules 16 are arranged side by side without any gap as described above. Sliding to is prevented. For this reason, in any of the solar cell modules 16, the solar cell module 16 cannot be slid in the ascending order, and the engaging portion 19 e of the support member 19 cannot be removed from the fitting groove 17 d of the guide support 17. The solar cell module 16 cannot be removed. Of course, since the slides of the solar cell modules 16 in the descending order are prevented by the stoppers 17f of the guide support members 17 in the order before the last order, the solar cell modules 16 are also slid in the descending direction. I can't.

  Therefore, after a plurality of solar cell modules 16 are arranged in parallel across the horizontal rails 15, the last guide support 17 on the horizontal rails 15 is temporarily removed, and the left and right sides of the respective guide support 17 are reversed. After that, each guide support 17 is fixed again on each crosspiece 15, and the end of each support member 19 is supported by each guide support 17, and the ascending order of the solar cell modules 16 in the last order If the sliding to the side is prevented, it becomes impossible to remove each solar cell module 16, and it becomes impossible to slide each solar cell module 16 in both the ascending order and the descending order.

  Thus, in the present embodiment, for each solar cell module 16, the solar cell module 16 is laid over each horizontal rail 15, the solar cell module 16 is slid, and both ends of each support member 19 of the solar cell module 16 are moved. By repeating the operation of inserting the engaging portion 19e into the fitting groove 17d of the guide support 17 of each horizontal rail 15 and fitting the engaging portion 19e to the stopper 17f, a plurality of suns are obtained. The battery modules 16 can be arranged in parallel across the horizontal rails 15.

The lateral width L2 of the back piece 42c is formed to a length that reaches the end of the main plate 15b (that is, the corner where the main plate 15b and the side plate 15a intersect).

  Thereby, when the solar cell module 16 is installed on the horizontal beam 15 of the gantry 10 (that is, when the contact portion 19f of the support member 19 is installed on the horizontal beam of the gantry), the buffer member 42 Since the back piece 42c comes into contact with the main plate 15b of the horizontal rail 15, the corner portion 181 of the solar cell panel 18 can be stably installed on the horizontal rail 15 of the gantry 10.

  Further, the buffer member 42 in FIG. 33 (b) is bonded to the edge surface 18b1, the edge side surface 182 and the edge back surface 18c1 of the solar cell panel 18 in the same manner as the buffer member 42 shown in FIG. 33 (a). However, since it is formed in a U-shaped cross section, an adhesive member may not be used and a structure that is simply fitted and fixed may be used. The buffer member 42 may be detached from the corner portion 181 of the solar cell panel 18 simply by being fitted and fixed. However, in the state where each solar cell module 16 is installed on the gantry 10 as described above, Since the solar cell modules 16 to be arranged are arranged so as to be in contact with each other with almost no gap, there is no fear that the buffer member 42 is unexpectedly detached after the arrangement.

  In the present embodiment, the length L1 of one side of the buffer member 42 is about 150 mm. That is, as shown in FIG. 34, a gap t22 of about 50 mm is provided between the tip 421a of one side 421 of the buffer member 42 arranged along the short side end of the solar cell panel 18 and the support member 19. It is provided as possible. The gap t22 is provided to be slightly wider than the longitudinal width t21 (about 45 mm to 50 mm) of the side portion 17d constituting the fitting groove 17d of the guide support 17.

  Accordingly, when the engaging portion 19e of the support member 19 is inserted into the fitting groove 17d of the guide support 17 in order to install the solar cell module 16 on the horizontal rail 15 of the gantry 10, it is shown in FIGS. Thus, in the state which shifted the edge part which the support member 19 of the solar cell module 16 protruded from the guide support 17 of the horizontal rail 15 to the horizontal direction (X direction), the protrusion of the support member 19 of the solar cell module 16 The finished end is placed on the main plate 15b of the crosspiece 15. At this time, by positioning the side portion 17d of the guide support 17 in the gap t22 between the tip portion 421a of one side 421 of the buffer member 42 and the support member 19, the buffer member 42 interferes with the engagement. There is no. In this state, as shown in FIG. 35, the contact portion 19 f of the support member 19 is brought into contact with the main plate 15 b and the side plate 15 a (the corner portion of the horizontal beam 15) of the horizontal beam 15. By this contact, the engaging portion 19e of the supporting member 19 is positioned with respect to the corner portion of the horizontal rail 15, and when viewed from the X direction (the direction perpendicular to the paper in FIG. 35), the engaging portion 19e of the supporting member 19 is It overlaps with the fitting groove 17d of the guide support 17.

  In this state, as shown in FIGS. 37 and 38, the solar cell module 16 is slid in the X direction (rightward in the figure), and the contact portion 19f of the support member 19 is moved to the main plate 15b and the side plate 15a of the cross rail 15. , The engagement portion 19e of the support member 19 enters from the opened end of the fitting groove 17d of the guide support device 17, and the engagement portion 19e of the support member 19 is fitted to the guide support device 17. It fits in the mating groove 17d. When the solar cell module 16 is further slid in the X direction (rightward in the figure), the side plate 19b of the support member 19 comes into contact with a stopper 17f provided at the other end of the fitting groove 17d of the guide support 17. .

  Thereby, the edge part of the transversal direction of the solar cell module 16 is supported on the main plate 15b of the crosspiece 15. At this time, since both ends of the solar cell panel 18 in the short direction are also supported on the main plate 15b of the horizontal beam 15 via the buffer member 42, the solar cell module 16 is more stably installed on the horizontal beam 15. Can do.

  In the embodiment of the buffer member 42 described above, a gap t22 is formed between the support member 19 and the tip 421a of one side 421 of the buffer member 42 arranged along the short-side end of the solar cell panel 18. However, as shown in FIG. 39, the tip 421 a of one side 421 of the buffer member 42 may be provided so as to contact the side plate 19 b of the support member 19. Thereby, the protection area | region of the corner part 181 of the solar cell panel 18 can be taken widely.
