Description

  The present invention relates to a solar cell module that generates power using solar energy, and a solar cell array in which a plurality of solar cell modules are installed on a roof of a building, and these solar cell modules are tiled.

  Conventionally, for example, as shown in FIG. 32, in order to reduce the electric load at home, a roof tile-integrated solar cell module 30 that converts solar energy into electric energy is arranged on a roof of a house in a tiled manner. Is known.

  In the case of such a tile-type solar power generation roof 400, as shown in FIG. 33, the solar cell module 30 is provided with a transparent material such as glass or resin on the upper part of a tile-shaped main body 31 having substantially the same shape as the tile material 10. A solar cell 32 composed of a plurality of solar cells bonded to an optical substrate is embedded therein, and the tiled body 31 and the solar cell 32 are integrated with an adhesive such as a resin. I have. Since the solar cell module 30 is not different in shape from the tile material 10 having no solar cell 32, the solar cell module 30 can be disposed on the roof in the same manner as the normal tile material 10 is installed. The tile material 10 can be sequentially tiled on the pier 9 arranged on the main plate 33 from the eaves of the roof. In general, the output wiring 34 output from the solar cell module 30 passes through a gap between the tile material 10 and the ground plate 33 generated by the overlapping of the tile material 10.

  Further, as shown in FIG. 34B, the tiles are formed on one of the two tiles 10 adjacent to each other in a direction parallel to the roof ridge, that is, in a horizontal direction parallel to the roof surface. The upper protruding portion 35 protruding downward and the lower protruding portion 36 formed on the other tile material 10 and protruding upward are engaged with each other so that the tile materials 10 are not easily displaced from each other.

Further, as shown in FIG. 34 (b), a snow stopper provided with a snow stopper 29 projecting upward to prevent falling snow is provided on the tile material 10 disposed near the eaves of the house. A flat roof tile 27 or a corrugated roof tile 28 may be provided.

  However, since it is necessary to fix and wire the tile material 10 while partially stacking it on the roof surface as described above, when all the wiring work is completed, together with the connection of the solar cell modules and the like, the solar cell module Fixing to the roof surface is completed.

  Therefore, if it becomes necessary to remove the solar cell module from the roof surface later due to a connection error or the like, the operation becomes complicated, which is a problem.

  Also, in the maintenance and inspection work of the solar cell module and the like, it is not easy as long as the operation requires removal of the solar cell module.

  Further, as described above, when a protrusion for snow protection is provided in a roof tile-integrated solar cell module, not only the light receiving area (power generation area) of the solar cell module becomes small, but also the protrusion creates a shadow. Occurs. Further, if the ordinary snow-blocking tile material 10 is used to solve the problem, not only the construction becomes complicated, but also the weight increases around the snow-blocking portion due to the blocked snow. In addition to the need to have the strength to withstand the overload, it is necessary to prepare two types of tile materials 10, a tile material 10 with snow stopper and a general tile material 10. Is complicated and problematic.

  As a method of snow stopper and wiring, a solar cell integrated roof material (see, for example, Patent Document 1) or a solar cell integrated roof material in which a convex portion is provided on the surface and used as a storage portion for a snow stopper and a terminal take-out portion (For example, see Patent Document 2), but the above-mentioned problem cannot be solved.

  In the case of a tiled solar power generation roof 401 shown in FIG. 35, the solar cell module 130 includes a solar cell 132 formed by bonding a solar cell with a light-transmitting substrate such as glass or resin. A frame 108 made of metal or the like having a mounting structure / waterproof structure replaceable with 110 is mounted. The solar cell module 130 can be mixed with a tile material 110 having no other solar cells.

  However, when the solar cell module 130 is tiled as described above, the gap generated by overlapping is smaller than when a general tiled roof is used, and the air permeability is poor. In particular, when the frame 108 is made of a metal manufactured by extrusion molding or the like, it is difficult to discharge moisture due to rainwater blowing or dew condensation or hot air accumulated on the tile back in summer or the like. In addition, there are problems such as noise due to creaking and abrasion of the rail material coating at the overlapping portion of the tile material 110 and the solar cell module 130, and between the solar cell modules 130. Furthermore, when the solar cell module 130 is installed on the tiles in this way, there is a problem that when the solar cell module is replaced for maintenance or the like, the attachment and detachment of the module become complicated.

As shown in FIG. 36, on the other hand, as a method for preventing rainwater from blowing, it has been proposed to sandwich a synthetic resin foam between the ridge-side frame 126 of the lower solar cell module and the eave-side frame 127 of the upper solar cell module. I have. (For example, see Patent Document 3)
In addition, as a method of ventilating the back surface of the tile, a method of opening a slit in the eave side frame 127 has been proposed. (For example, see Patent Document 4)
Although this method can reduce the blowing of rainwater, it has a problem that it is more difficult to discharge the rainwater and moisture due to condensation once the water has entered, and there is a problem that water accumulated inside causes corrosion of metal.

And a casing-side fixing portion 332 to be fixed to the fixing portion 311. The displacement prevention portion 331 has a locking recess 333 into which the locking portion 21 provided on the eaves-side solar cell module, the eaves-side tile member, or the base plate is fitted.

  The casing-side fixing part 332 is formed at a position facing the solar cell-side fixing part 311 in a state where the solar cell unit 50 is mounted on the casing 51. The casing-side fixing portion 332 has a screw hole coaxial with an insertion hole formed in the solar cell-side fixing portion 311. The screw hole has a smaller diameter than the insertion hole. When the fastening screw 19 serving as a connecting member passes through the insertion hole of the solar cell side fixing portion 311 and engages with the screw hole of the casing side fixing portion 332, the solar cell portion 50 and the casing 51 are detachably fixed. You.

  Further, the eave-side fixing bracket 17 is formed with a fitting hole 334 having an opening upward in cooperation with the long support 16. When the fitting portion 312 of the eave-side long side frame 13 is fitted in the fitting hole 334 in a state where the solar cell portion 50 is mounted on the casing 51, the solar cell portion 50 and the casing 51 in the tilt direction X are fitted. Positioning can be easily performed.

  The ridge-side fixture 18 extends below the long support 16 and extends above the long support 16 with the second leg 340 abutting on the field board, and the distal end portion 341 becomes the remaining portion 342. On the other hand, a guide portion 343 bent toward the eaves side is formed. The second leg portion 340 abuts on the field board and also comes into contact with an asagi provided on the field board from the ridge side. This prevents the casing 50 from being aligned with the base plate and displaced downward. The guide part 343 is opened to the eaves side, and a locking space 344 is formed in which the locking part 304 of the solar cell unit 50 is loosely fitted. By providing the guide portion 343, the solar cell portion 50 can be easily guided to the mounting position provided on the casing 50.

  When the legs 330 and 340 of the eave-side fixing bracket 17 and the ridge-side fixing bracket 18 abut against the base plate, both ends of the long support 16 can be supported. The portion 50 can be stably supported. Further, since the two casings 51 support both sides in the width direction of the solar cell unit 50, the solar cell unit 50 can be supported more stably. When the terminal box 350 to which the output wiring 6 is connected is formed in the solar cell unit 50, the two casings 51 are arranged at an interval to prevent the terminal box 350 and the casing 51 from interfering with each other. be able to.

  Further, as shown in FIG. 4, a projection 308 projecting from the lower surface 309 of the base 301 of the ridge-side long side frame 12 may be formed, and a recess 321 may be formed on the upper surface 320 of the long support 16. When the projection 308 is fitted into the recess 321 in a state where the solar cell unit 50 is mounted on the casing 51, the solar cell unit 50 and the casing 51 can be aligned. In a state where the solar cell unit 50 is mounted on the casing 51, the solar cell 11 and the casing 50 are arranged at an interval L1 in the vertical direction Z. Thus, even if the accuracy of the casing 51 and the solar cell 50 is low, the solar cell unit 50 and the casing 51 can be securely mounted.

  The frame cover 2 covers the eaves-side long side frame 13 in a state where the solar cell unit 50 is mounted on the casing 51. As shown in FIG. 4, a first engagement recess 351 and a first engagement protrusion 352 are formed in the solar cell-side fixing portion 311 of the eave-side long side frame 13. The first engagement recess 351 and the first engagement protrusion 352 extend in the width direction Y. The frame cover 2 has a second engagement protrusion 353 that engages with the first engagement recess 351, and a second engagement recess 354 that engages with the first engagement protrusion 352. The second engagement protrusion 353 of the frame cover 2 engages with the first engagement recess 351, and the first engagement protrusion 352 of the solar cell side fixing portion 311 engages with the second engagement recess 354 of the frame cover 2. The combination prevents the frame cover 2 from being displaced in the tilt direction X. In addition, when the frame cover 2 is mounted on the solar cell side fixing portion 311 in a state where the fixing bolt 19 fixes the solar cell side fixing portion 311 and the casing side fixing portion 332, the fixing bolt 19 can be hidden.

  The frame cover 2 includes, in addition to the main body 355 in which the second engagement protrusion 353 and the second engagement recess 354 are formed, a movable portion provided to be displaceable in the tilt direction X with respect to the main body 355. And an elastic force generating means for applying an elastic force toward the upward direction X1 to the movable portion. In the present embodiment, the movable part and the elastic force generating means are realized by the spring 3. In this case, the tip of the spring 3 becomes a movable part. The distal end portion of the spring 3 is locked to the solar cell-side fixing portion 311 or the casing-side fixing portion 332, thereby preventing the frame cover 2 from being displaced in the vertical direction Z. In addition, a force opposing the spring force of the spring 3 is applied to move the distal end of the spring 3 downward in the inclining direction X2, so that the distal end of the spring 3 and the solar cell side fixing portion 311 or the casing side fixing portion 332 are connected. The locked state can be released. As shown in FIG. 5, the solar cell module 1 can be installed on a roof of a building by being mixed with a ceramic or metal tile 10. The solar cell module 1 can be installed surrounded by the tile material 10, installed with the tile material 10 disposed between the solar cell modules 1, or installed on the entire surface of the roof. In addition, although the tile material 10 in the figure is a flat tile having a flat appearance, a wavy tile having a wavy surface may be used, and a construction method of alternately disposing tiles on the ridge side and the eave side is adopted. However, a method in which tiles are arranged in a straight line from the ridge to the eaves may be adopted. Further, it is preferable that the length of the solar cell module 1 is set to be substantially an integral multiple of the outer dimension of the material tile 10 (or the width of the surface of one tile when the tiles are stacked). When the solar cell modules are arranged in the inclination direction X, of the two solar cell modules 1 arranged in the inclination direction X, the casing 51 of the solar cell module 1 on the eaves side and the casing 51 of the solar cell module 1 on the ridge side Is preferably shifted in the width direction Y. This can prevent the casing 51 of each solar cell module 1 from interfering.

  Next, a method of installing the solar cell module 1 on the roof in a manner mixed with the tile material 10 will be described. As shown in FIGS. 6 to 8, the tile material 10 is installed so as not to slip down to the eaves side in such a manner that a dent is hooked on the pier 9 arranged on the field board 33. The eaves-side receiving bracket 20 is fixed to the roof plate 33 on the ridge side of the tile material 10 with screws or nails, and the metal-equipment locking portion 21 of the eaves-side receiving bracket 20 is attached to the eaves-side of the solar cell module 1. The solar cell module 1 is moved so as to be accommodated in the locking recess 333 formed in the displacement preventing portion 331 of the fixing member 17. Thereby, the solar cell module 1 can be fixed on the roof, and the tile material 10 and the solar cell module 1 can be tiled like tiles. The solar cell module 1 is prevented from moving to the eaves side, and the eaves-side end 361 of the solar cell module 1 is arranged above the ridge-side end 360 of the tile material 10. At this time, the casing 51 supports the solar cell unit 50 in a state where the solar cell unit 50 is spaced apart from the tile material 10 in the vertical direction Z by an interval L2. The ridge-side fixing bracket 18 of the solar cell module 1 is fixed by hitting it on a field board with a nail 24 or a screw nail.

  As shown in FIG. 9, the locking portion 21 may be formed at the ridge side end 361 of the tile material 10. In this case as well, the solar cell module 1 is moved so that the locking portion 21 is accommodated in the locking recess 333 formed in the displacement preventing portion 331 of the eave-side fixing bracket 17 of the solar cell module 1 as described above. Then, the solar cell module 1 is fixed to the base plate 33.

  Similarly, in the case of the tiled stack of the solar cell modules 1, as shown in FIGS. 10 to 12, the locking portion 304 of the ridge-side long side frame 12 of the eave-side solar cell module 1 </ b> A is By moving the ridge-side solar cell module 1B so as to be accommodated in the locking recess 333 formed in the displacement prevention portion 331 of the eave-side fixing bracket 17 of the solar cell module 1B, as shown in FIG. The battery modules can be tiled.

  The eaves-side long side frame 13 of the ridge-side solar cell module 1B fixed in this manner is disposed so as to cover the upper part of the ridge-side long side frame 12 of the eaves-side solar cell module 1A. The frame cover 2 attached to the eaves-side long side frame 13 of the solar cell module 1B and the stopper pieces 302 and 303 of the eaves-side solar cell module 1A form a rain repelling structure to prevent rain and wind from entering as much as possible. are doing. That is, the frame cover 2 extends in the width direction Y over the entire length of the eave-side long-side frame 13 in the width direction Y, and extends to a position close to the ridge-side long-side frame 12 of the eave-side solar cell module 1A in the vertical direction Z. Similarly, the stopper pieces 302 and 303 extend in the width direction Y over the entire length of the ridge-side long side frame 12 in the width direction Y, and approach the vertical direction Z to the eave-side long side frame 13 of the ridge-side solar cell module 1B. Extend to the position you have set.

  Further, by making the space between the frame cover 2 and the upper part of the screw of the fastening screw 19 shorter than the total length of the screw, the screw head is held down so that the fastening screw 19 is not completely dropped when it is loosened. I can put it.

  FIGS. 13A to 13D show a method of attaching the frame cover 2. As shown in FIG. 13A, a spring 3 having an inclined portion 61 is attached inside the frame cover 2. The upper surface of the inclined portion 61 is inclined downward Z2 as it goes to one inclination direction X1. In addition, as shown in FIG. 13B, the second engagement protrusion 353 which is a locking member of the frame cover 2 is connected to a first engagement member which is a locking member of the eave-side long side frame 13 of the solar cell module 1. Lightly insert into the recess 351 and push diagonally downward. As a result, as shown in FIG. 13C, the spring 3 is compressed by elastic deformation, and the second engagement recess 354 serving as a locking member of the frame cover 2 is locked by the locking of the eave-side long side frame 13. The first engagement protrusion 352, which is a member, is moved onto the first engagement protrusion 352, and the second engagement protrusion 353 and the first engagement recess 351 and the second engagement recess 354 and the first engagement protrusion 352 are moved to (d) in FIG. ) Can be fitted respectively. At this time, the spring 3 moves to a position where the inclined portion 61 faces the lower surface of the eave-side long side frame 13 due to the restoring force. Accordingly, the displacement of the frame cover 2 toward the upper side Z1 with respect to the eaves side long side frame 13 is prevented, and the frame cover 2 and the eaves side long side frame 13 are firmly held.

  The inclined portion 61 can move up and down the contact point with the eaves-side long side frame 13 depending on the degree of inclination, and absorbs a dimensional error and accuracy of the long side frame 13, the frame cover 2, or the spring 3 itself. be able to. Also, it has a function of loosening the fitting accuracy between the eaves-side long side frame 13 and the frame cover 2. Further, by providing a spring projection 62 that is inclined upward Z1 toward the other inclination direction X2 at the tip of the inclined portion 61, the spring projection 62 stands up on the eaves-side long side frame 13, and the spring 3 Is hardly shrunk, and the holding of the frame cover 2 can be further strengthened. Further, in the above-mentioned method, since screws or the like for fixing the frame cover 2 itself need not be provided on the surface, there are advantages such as improvement of the appearance and no need for a waterproof structure of the screw portion. Since there is no need to separately prepare members, the mounting operation is simple.

  The spring 3 may be attached to the frame cover 2 with an adhesive, a screw, a rivet or the like, or may be inserted into a slit formed in the frame cover 2 as shown in FIG. The spring 3 inserted into the slit is formed so as to be movable in the width direction Y. In addition, the number of pieces to be attached to the frame cover 2 may be selected according to the length of the frame cover 2 and the elastic strength of the spring 3, and the strength of the product can be changed by adding for reinforcement at the time of installation on the site. It is possible to respond with members, and it is possible to reduce the types of products.

  Next, FIGS. 15A to 15D show a method of removing the frame cover 2. As shown in FIG. 15A, after the removal jig 40 is inserted into the inside of the frame cover 2 from below the frame cover 2, the spring 3 is compressed by pulling in the direction of the arrow in the figure. When the spring 3 is compressed, the locking of the solar cell module 1 to the eaves-side long side frame 13 is released as shown in FIG. You will be able to pass. That is, the frame cover 2 can be removed from the eave-side long side frame 13. For this reason, it lifts up as shown by the arrow in the figure, and as shown in FIG. 15C, the second engagement protrusion 353 and the first engagement recess 351, and the second engagement recess 354 and the first engagement recess 354. The engagement of the engagement projection 352 is released, and the frame cover 2 can be easily removed as shown in FIG.

  Since the frame cover 2 can be easily removed in this way, the installation is completed once as shown in FIG. 16A, and the solar cell module 1A on the eaves side and the solar cells on the ridge side After engaging with the module 1B, by removing the frame cover 2 of the solar cell module 1A on the eaves side, the fastening screw 19 connecting the solar cell unit 50 and the casing 51 can be easily removed. As shown in FIG. 16B, by removing the frame cover 2 of the solar cell module 1B on the ridge side, the solar cell unit 50 of the solar cell module 1A on the eave side can be removed. Further, the fitting of the solar cell modules 1A and 1B can be easily performed in the reverse order. Using this, for example, as shown in FIG. 17, when the frame cover 2 is removed, the eaves-side solar cell module 1B and the eaves-side long-side frame 13 of the eaves-side solar cell module 1A can be used. Since there is a gap leading to the back surface of the battery module 1A, it is possible to draw out the output wiring 6 of the solar cell module 1A on the eave side therefrom. Therefore, when the solar cell module 1 is installed, the frame cover 2 is removed, and the output wiring 6 of the solar cell module 1 is drawn out. The frame cover 2 is attached after being pushed into the back surface.

  Accordingly, the work of disposing the solar cell module 1 and the connection of the output wiring can be performed separately, so that a complicated construction method in which a wiring step is performed during the disposition of the solar cell module 1 is simplified, and the operation is smoothly performed. It can be an installation work. In addition, the wiring can be stored after confirming the connection state of the output wiring, so that a wiring error is less likely to occur. Further, when there is a problem in the wiring, the connection state can be easily confirmed and corrected only by removing the frame cover 2.

  Further, by utilizing the fact that the frame cover 2 of the solar cell module 1 is removable, as shown in FIG. 18, the snow stopper cover 5 provided with the snow stopper mechanism 4 (snow stopper) on the eaves side frame can be detached. Can be attached to By using a snow stopper cover 5 having a snow stopper protrusion 4 (snow stopper) projecting upward from the light receiving surface as a frame cover, a snow stopper structure can be provided at an arbitrary position on the roof. Therefore, it is not necessary to manufacture a special solar cell module 1 corresponding to a snow stopper, and it is not necessary to separately manage and install the solar cell module 1 for a snow stopper and a solar cell module 1 that is not. Simplified.

  In addition, since only the frame cover 2 needs to be changed for snow stoppers, it is easy to change specifications after the completion of construction. Furthermore, since the snow cover 5 can be arranged at any position of the solar cell module 1, the snow cover 5 is arranged not only on the eaves side on the roof but also on the middle and the ridge side, so that the heavy snow accumulation can be prevented. Since consideration can be given not to concentrate on some of the solar cell modules 1, the strength required for the solar cell module itself can be reduced.

  Further, as shown in FIG. 19, when the solar cell modules 1 are arranged in the inclination direction X, the positions of the upper solar cell module casing 51 and the lower solar cell module casing 51 are shifted in the width direction Y. The solar cell array 90 can be formed while preventing interference of the casing.

  As described in detail above, in the solar cell array 90 in which the solar cell modules 1 are tiled, even if the solar cell modules 1 are partially covered with other solar cell modules or tiles, The solar cell module can be easily removed, the solar cell can be easily replaced, maintenance and inspection work can be performed easily, and the connection between the solar cell modules can be confirmed and easily performed. Further, even if there is an error in the connection or the like, or the construction is redone, it is possible to correct the construction in a very short time.

  Hereinafter, embodiments of a solar cell module 101 according to the present invention and a solar cell array 91 using the same will be described in detail with reference to the drawings schematically shown. 20 is a perspective view of the solar cell module 101 as viewed from the light receiving surface side, FIG. 21 is a sectional view, FIG. 22 is an exploded perspective view, and FIG. 23 is an exploded sectional view of FIG. FIG. 24 shows a state in which a solar cell array 91 formed by connecting and connecting a plurality of the solar cell modules 101 is arranged on a part of a roof 98 of a building. 25 to 31 show partial cross-sectional views of the solar cell module 101.

  As shown in FIG. 20, the solar cell module 101 includes a solar cell unit 150 having a plate-shaped main body having a power generation function and a substantially rectangular planar shape, a casing 151, and a frame cover 102. The solar cell section 150 includes a solar cell 111, a ridge-side long side frame 112, an eave-side long side frame 113, and a side frame 114. The solar cell 111 is formed by bonding a light-transmitting substrate such as glass or resin and a plurality of solar cells. The ridge side long side frame 112 is arranged on the ridge side of the solar cell 111 and is attached to the solar cell 111. The eaves side long side frame 113 is arranged on the eaves side and attached to the solar cell 111. The side frames 114 are arranged on both left and right sides of the solar cell 111 and are attached to the solar cell 111. The frame cover 102 is attached to an eave-side long side frame 113 arranged on the eave side, and abuts on the eave-side frame of another solar cell module 101. The casing 151 supports the solar cell unit 150 and fixes it to a roof or the like. As shown in FIG. 21, the solar cell unit 150 and the casing 151 are composed of a casing formed by attaching an eave-side fixing metal 117 and a ridge-side fixing metal 118 to a fixed rail 116 provided on the back surface of the solar cell unit 150, and a fastening screw 119. Has been concluded. That is, as shown in FIG. 24, the solar cell module 101 is configured such that the solar cell unit 150 and the casing 151 are detachably accommodated in the casing 151 having one end mounted on a roof, and the solar cell unit 150 for performing power generation is detachably accommodated. They are connected by screws 119. The coupling screw 119 is covered by the frame cover 102 to which the eave-side long side frame 113 is attached so that the gap is hardly seen from the outside. In the present embodiment, since the frame cover 102 is mounted, the front surface of the frame cover 102 forms the eave side surface 102d. A spring 103 supported by the eave-side long side frame 113 is attached to the inside of the frame cover 102, so that the frame cover 102 can be easily attached and detached to facilitate access to the fastening screws 119. .

  The solar cell module 101 shown in FIGS. 20 to 23 has almost the same configuration as the solar cell module 1 shown in FIGS. Therefore, as the reference numerals of the solar cell module 101 shown in FIGS. 20 to 23, values obtained by adding 100 to the reference numerals of the configuration of the solar cell module shown in FIGS. 1 to 4 are used. In addition, the description of the same configuration may be omitted.

  On the other hand, below the eave-side long side frame 113 of the solar cell unit 150, a frame lower support 113a for supporting a load from the front side of the solar cell module 101 is provided. Are provided with upper frame stopper protrusions 402 and 403 for receiving the lower frame support portion 113a. The lower frame supporting portion 113a may be received by the first frame upper stopper projection 402 and / or the second frame upper stopper projection 403.

  Hereinafter, the construction method of installing the solar cell array 91 on the roof of the house by mixing the solar cell module 101 with the tile material 10 is the same as described above. That is, the solar cell module 101 can be installed on the roof 133 of the building in a mixed manner with the ceramic or metal tile material 10. The solar cell module 101 can be installed between the modules 101 or the entire surface of the roof. In addition, although the tile material 10 is a flat tile having a flat appearance, the tile material may be a corrugated tile, and the tile material from the ridge to the eave is also used in the construction method in which the ridge side and the eave side tile materials are alternately arranged. They may be arranged in a straight line. Further, it is preferable that the length of the solar cell module M is set to be substantially an integral multiple of the outer dimensions of the tile material 10 (or the width of the surface of one tile when the tiles are stacked).

  As shown in FIG. 25 to FIG. 27, the tile material 10 is installed so as not to slip down to the eaves side by hooking a dent on the pier 9 arranged on the field board 33. A support fitting 120 is fixed to the roof base plate 33 on the ridge side of the tile material 10 with screws or nails, and the fitting locking portion 121 of the support fitting 120 is displaced by the displacement of the eave-side fixing fitting 117 of the solar cell module 101. The solar cell module 101 is fixed on the roof so as to be accommodated in the locking recess 433 formed in the blocking portion 431. Thereby, the tile material 10 and the solar cell module 101 can be tiled like tile materials. The ridge-side fixing bracket 118 of the solar cell module 101 is fixed to the roof by hitting the field plate 33 with a nail or a screw nail or the like to fix the solar cell module 101 on the roof.

  Similarly, in the case of the solar cell modules 101, as shown in FIGS. 28 to 29, the locking portion 404 (ridge-side end) of the ridge-side long side frame 112 of the eave-side solar cell module 101 </ b> A is connected to the ridge-side. 30A by holding in the locking recess 433 formed in the displacement prevention portion 431 of the eaves-side fixing bracket 117 of the solar cell module 101B, and clamping the locking portion 404 by the displacement prevention portion 431. ) And fixed in a tiled pattern. At this time, the ridge-side solar cell module 101B is arranged so as to cover the upper part of the ridge-side long side frame 112 of the eave-side solar cell module 101A, but the casing 151 does not block the eave-side solar cell module 101A. It is installed with an empty space 500 left.

  Further, an opening 501 to the space is provided along the entire length of the eave side surface 102d in the solar cell module 101B on the ridge side.

  As shown in FIGS. 20 to 23, two casings 151 are attached to the solar cell unit 150, and a portion without the eave-side fixing bracket 117 has a cross section as shown in FIG. The ventilation through the ventilation passage 502 is possible, and the first frame upper stopper projection 402 and the second frame upper stopper projection 403 of the solar cell module 101 and the frame lower support 113a of the ridge-side solar cell module 101B are provided. Through the gap, it is possible to discharge moisture that has entered due to rain or dew condensation, and hot air under the roof generated in summer or the like.

  Further, the first frame upper stopper protrusion 402 has a structure inclined toward the eaves side, and has a structure in which rainwater is hard to blow. Further, rainwater that has entered over the first frame upper stopper projection 402 is also dammed by the second frame upper stopper projection 403 and is inclined by the first frame stopper upper projection 402 inclined to the eaves side. It is discharged without collecting on the back side of the upper projection stopper 402.

  On the other hand, in the case of such a structure, when a snow load or a load such as an operator riding on the module is applied to the portion where the casing 151 is not provided, the eaves side of the solar cell module 101B on the ridge bends downward, and Therefore, there is a possibility that the eaves-side long side frame 113 is deformed and cannot be returned, the frame cover 102 is detached, or a part where rainwater is accumulated due to deformation. Therefore, as shown in FIG. 30C, a frame lower supporting portion 113a for supporting the load of the eave side surface 102d is provided below the eave side long side frame 113 of the solar cell module 101B on the ridge side, and the load is applied. At least one of the frame upper stopper protrusions 402 and 403 of the ridge-side long side frame 112 of the eaves-side solar cell module 101A supports this, and the ridge-side long side frame 112 of the eaves-side solar cell module 101A. Thus, the solar cell module 101B on the ridge side and the load applied thereto are supported.

  In this way, even when a load is applied by an operator or the like on the solar cell module 101 or the like, the eaves-side long side frame 113 of the solar cell module moves slightly downward and immediately moves to the upper part of the frame. Since it is supported by the stopper projections 402 and 403, the four-sided frame of the solar cell module 101 is not easily deformed. The same applies to an average load such as snow.

  Here, it is important that the stopper protrusions 402 and 403 are provided on the ridge side of the eave side surface 102d of the ridge side solar cell module 101B. In the present embodiment, the stopper projections 402 and 403 are provided on the solar cell module 101A on the eave side, but may be provided on the solar cell module 101B on the ridge side.

  Further, even when a load is applied, the frame cover 102 is not pressed against the solar cell module 101A on the eaves side and does not scrape the surface, so that the external appearance of the solar cell module can be protected. In addition, the frame upper stopper projections 402 and 403 and the frame lower support 113a, which are support portions for supporting the load, are both provided along the entire length of the eave side surface 102d, and are the top portions of the rain return where rainwater does not collect. There is no danger of affecting product quality even if peeling such as surface treatment occurs due to load. Furthermore, since the contact portions of the solar cell modules 101 are normally separated from each other, no squeaking noise or the like is generated.

  Next, a method of removing the solar cell module for maintenance or the like will be described.

  When removing the solar cell module 101B once installed as shown in FIG. 31A, the frame cover 102a of the solar cell module 101 to be removed is removed as shown in FIG. 31 can be easily removed, and the frame cover 102b of the solar cell module 101C on the ridge side of the solar cell module 101B to be removed, as shown in FIG. 31 (c).
