  By the way, a waterproof material is provided on the roof of the building, and the waterproof performance is given to the roof by the waterproof material. In this case, since there is a concern that the waterproof performance of the roof is deteriorated due to aged deterioration of the waterproof material, maintenance work for maintaining the waterproof performance of the roof is performed. For example, a maintenance work is performed in which a new waterproof material is attached to a roof when a predetermined number of years have passed after building construction.

  Here, when a solar panel is installed on the roof, it is considered difficult to perform maintenance work on the roof below the solar panel because the work space is narrow. In addition, it is conceivable to secure a work space by removing the solar panel from the roof, but it is assumed that a heavy machine such as a crane is used when removing and re-installing the solar cell. In this case, even if the installation work of the solar panel is facilitated as in Patent Document 1, it is considered that the work load for attaching and detaching the solar panel during the maintenance work of the roof is large.

  An object of the present invention is to provide a photovoltaic power generation facility capable of facilitating roof maintenance work and related work.

  In order to solve the above problems, a first invention is a photovoltaic power generation facility provided with a plurality of solar panels provided side by side on a roof of a building and generating power by irradiating sunlight onto a light receiving surface. And a rail portion provided on the roof, and a support member that is movable along the rail portion and supports the plurality of solar panels, wherein the solar panel is the support member. In such a state, at least a part of the solar panel is movable to a position where it vertically overlaps with the adjacent solar panel.

  According to the first invention, in the configuration in which the plurality of solar panels are provided on the roof, the solar panels can be moved while being supported by the support member, and thereby the solar panels can be stacked. Therefore, the work space for the maintenance work of the roof can be ensured in the part where the solar panel before moving exists. Therefore, the work can be facilitated as compared with the case where the maintenance work is performed in a narrow work space. In addition, when securing the work space, it is not necessary to perform the work of removing the solar panel from the roof and the work of re-installing the solar panel on the roof, so that the work related to the maintenance work can be facilitated. As a result, the roof maintenance work and the related work can be facilitated.

  In a second invention, in the first invention, the plurality of solar panels are installed on the roof in such a manner that the respective light receiving surfaces are obliquely upward in the same direction and aligned in the inclination direction, and the rail portion Is extended in the arrangement direction of the solar panels, and the support member is provided on a side of the plurality of solar panels in a plan view and at a position different from the panel movable range on the roof. ing.

  According to the second invention, in the configuration in which one of adjacent solar panels enters the lower side of the other so that the solar panels overlap, the support member is provided at a position different from the panel movable range of the solar panel. Therefore, it can avoid that a lower solar panel contacts the support member of an upper solar panel. Therefore, compared with the structure in which the support member is present below the solar panel, the amount of overlap between the solar panels (overlap amount) can be increased. That is, the work space for the maintenance work of the roof can be increased.

  In 3rd invention, in the 2nd invention, it is a photovoltaic power generation facility by which the said solar panel is supported by the high-order side and the low order side, Comprising: The said supporting member supports the high-order side of the said solar panel. A low-side support member that supports the low-side of the solar panel is provided separately from the high-side support member, and the rail portion guides the movement of the high-side support member A high-side rail portion, and a low-side rail portion that guides the movement of the low-side support member is provided separately from the high-side rail portion, and the high-side support member and the high-side rail portion are: In a plan view, the solar panel is located on a side of the plurality of solar panels and at a position different from the panel movable area on the roof, and the lower support member and the lower rail portion are positioned at the panel movable area. Is provided.

  According to the third aspect of the invention, in the configuration in which the support strength of the solar panel is increased by supporting the solar panel with the lower support member in addition to the higher support member, the lower support member is the solar panel support. It is provided in the panel movable range. In this case, the area that is not the panel movable range can be reduced as compared with the configuration in which both the high-level support member and the low-level support member are provided at positions different from the panel movable range. Moreover, even if the lower support member is provided in the panel movable range, it is difficult for the solar panels to overlap each other, so that the amount of overlapping of the solar panels can be ensured.

  In a fourth invention, in the third invention, the lower support member is provided at the lower tip of the solar panel.

  In a configuration in which one of adjacent solar panels enters the lower side of the other and the solar panels overlap, when the low-level support member is provided in the panel movable range, the overlapping amount of the solar panels is It is determined by the positional relationship between the side solar panel and the lower support member of the upper solar panel. On the other hand, according to 4th invention, since the low-order side support member is provided in the front-end | tip of the low-order side of a solar panel, the amount which solar panels overlap can be enlarged as much as possible.

  According to a fifth invention, in any one of the first to fourth inventions, a non-permeable plate material is placed on the roof, and the rail portion is placed on the plate material. And the peripheral part of the said board | plate material is spaced apart outside from the mounting surface of the said rail part.

  According to the fifth invention, when a waterproof sheet having the same thickness as the thickness of the plate material is newly attached on the roof so as to surround the plate material, the upper surface of the plate material and the upper surface of the waterproof sheet form the same plane. It will be. Therefore, by newly attaching another waterproof sheet from the top to the boundary portion between the plate material and the waterproof sheet, it is possible to suppress a decrease in waterproof performance around the mounting portion of the rail portion.

  In the configuration in which the rail portion is supported by the gantry, the gantry is placed on the plate material. Therefore, it is preferable that the peripheral portion of the plate material is spaced outward from the placement surface of the gantry.

  In a sixth invention, in any one of the first to fifth inventions, the solar panel is provided with a buffer member that cushions the impact even if the solar panels come into contact with each other.

  According to the sixth invention, in the configuration in which the solar panels overlap with each other, it is possible to suppress the occurrence of breakage and deformation due to the contact of the solar panels.

  According to a seventh invention, in any one of the first to sixth inventions, there is provided a decelerating means for reducing a moving speed when the solar panel is moved.

  If the moving speed when the solar panel overlaps with the adjacent solar panel is large, the impact applied to the solar panel when stopped is increased. In this regard, according to the seventh aspect, since the solar panel being moved is decelerated, the impact generated with the stop is reduced. Therefore, it is possible to avoid damage and deformation of the solar panel due to the movement stop.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings. In the present embodiment, the present invention is embodied for a building in which a photovoltaic power generation facility is installed on a roof portion. FIG. 1 is a diagram showing a configuration around the roof portion 15 of the building 10, (a) shows a schematic plane around the roof portion 15, and (b) shows a schematic cross section around the roof portion 15.

  As shown in FIG. 1, a building 10 such as a house has a roof portion 15 provided above the first floor portion and the second floor portion. The roof portion 15 is a flat roof extending in the horizontal direction, and has a roof base material 16 configured to include a roof beam, a field plate, a heat insulating material, and the like. A waterproof layer 17 is provided on the roof base material 16. The waterproof layer 17 is formed of a waterproof sheet, a waterproof film, or the like, and is a roof finish that forms the roof surface 15a. The roof surface 15a extends in the horizontal direction.

  The roof portion 15 is provided with a parapet 18 as a rising wall extending along the peripheral edge of the roof surface 15a. The waterproof layer 17 extends along the side surface of the parapet 18 from the upper surface of the roof base material 16, and thereby waterproof performance is imparted to the entire roof portion 15 including the roof base material 16 and the parapet 18. .

  The building 10 is provided with a solar power generation device 21. The solar power generation device 21 includes a solar panel 22 that generates power when irradiated with sunlight, and the solar panel 22 is disposed above the waterproof layer 17 excluding the parapet 18 portion. The solar panel 22 is formed in a rectangular plate shape, and has a light receiving surface 23 on substantially the whole of one plate surface. The solar panel 22 is inclined with respect to the horizontal direction, and one of the pair of sides extending in parallel in the solar panel 22 is present at a lower position than the other. In this case, the light receiving surface 23 faces obliquely upward.

  The solar panel 22 is inclined by a predetermined angle (for example, 10 degrees) with respect to the horizontal direction, and is arranged so that the end of the predetermined direction (for example, south) is lower than the opposite end. Has been. Thereby, the light receiving surface 23 is easily irradiated with sunlight.

  A plurality of solar panels 22 are installed in the roof portion 15. The light receiving surfaces 23 of the solar panels 22 face the same direction, and the solar panels 22 are arranged side by side along the direction in which the light receiving surface 23 faces. In this case, the solar panels 22 do not overlap with each other in a plan view, and a shaded portion (a portion where no sunlight is irradiated) due to the other solar panels 22 does not occur on the respective light receiving surfaces 23. . In addition, regarding the adjacent solar panels 22, the lower end portion of one solar panel 22 exists on the higher end portion side of the other solar panel 22 in a plan view.

  Each solar panel 22 is supported by panel legs 25 and 26. The panel leg 25 is connected to the vicinity of the lower end of the solar panel 22, and the panel leg 26 is connected to the vicinity of the higher end. In this case, the angle of the solar panel 22 is kept constant by the panel legs 25 and 26. In the following description, the panel leg 25 is referred to as the lower panel leg 25 and the panel leg 26 is referred to as the higher panel leg 26. The lower panel leg 25 corresponds to a lower support member, and the higher panel leg 26 corresponds to a higher support member.

  By the way, in the roof part 15, there is a concern that the waterproof performance is deteriorated due to deterioration of the waterproof layer 17 over time. On the other hand, after the construction of the building 10, when a predetermined number of years (for example, 10 years) has passed, a maintenance work for the roof is performed in which a new waterproof material is attached to the existing waterproof layer 17 so as to be attached. The waterproof performance of the roof portion 15 is maintained. Here, when the solar panel 22 is installed on the roof portion 15, conventionally, the solar panel 22 is removed from the roof portion 15 using a heavy machine such as a crane, and then maintenance work is performed. A series of operations were performed in the procedure of installing the light panel 22 on the roof portion 15 again. In this series of work, there is a problem that the work burden and the cost burden when attaching / detaching the solar panel 22 are large.

  Therefore, in the present embodiment, in order to improve such a problem, a work space for maintenance work can be secured by moving the solar panel 22 in the roof portion 15. According to this configuration, it is not necessary to attach or detach the solar panel 22 from the roof portion 15, and preparation work for performing maintenance work on the roof can be facilitated.

  The roof portion 15 is provided with a lower support rail 31 that supports the lower panel leg 25 and a higher support rail 32 that supports the higher panel leg 26. In this case, the lower panel leg 25 is erected with respect to the lower support rail 31, and the higher panel leg 26 is erected with respect to the higher support rail 32.

  The support rails 31 and 32 extend linearly in the horizontal direction along the roof surface 15a above the waterproof layer 17, and are parallel to the direction in which the solar panels 22 are arranged. The high-side support rails 32 are provided on both sides of the solar panel 22 and extend so as to span the end portions of the solar panels 22. The high-order side panel leg portion 26 exists on the side of the solar panel 22 and is connected to the solar panel 22 from the side. In this case, the high-side panel leg 26 and the high-side support rail 32 are separated from the solar panel 22 in the direction orthogonal to the high-side support rail 32.

  The lower support rails 31 are provided near the respective higher support rails 32 below the solar panel 22. The lower support rail 31 is disposed between the higher support rails 32 and extends parallel to the higher support rail 32. The lower panel leg 25 is connected to the lower surface of the lower end of the solar panel 22.

  The lower panel leg 25 can move along the lower support rail 31. Specifically, the lower support rail 31 is formed with a groove extending in the longitudinal direction, and the lower panel leg 25 is formed with an engaging portion engaging with the groove. The engaging portion can be slid along. The lower panel leg portion 25 can move in either the approaching direction or the separating direction from the lower panel leg portion 25 that supports the other solar panels 22. Similarly, the high-side panel leg 26 can move along the high-side support rail 32, and approaches the high-side panel leg 26 that supports the other solar panels 22. In addition, it is possible to move in any direction.

  In the solar panel 22, the lower panel leg 25 moves along the lower support rail 31 and the high panel leg 26 moves along the higher support rail 32, so that the orientation of the light receiving surface 23 is increased. Is slid along the roof surface 15a. In this case, since the lower support rail 31 and the higher support rail 32 are provided, when the solar panel 22 moves, one lower panel leg 25 of the adjacent solar panels 22 and the other higher panel. The panel leg 26 does not come into contact. Moreover, since the high-side panel leg 26 is erected on the side of the solar panel 22, when the solar panel 22 moves, one of the adjacent solar panels 22 and the other high-side panel leg 26. There is no contact. Further, since one higher end of the adjacent solar panels 22 exists on the other lower end, the lower side of one solar panel 22 is moved when the solar panel 22 moves. As the lower side of the other solar panel 22 enters the side, the solar panels 22 can be obliquely overlapped.

  Therefore, when the solar panel 22 relatively moves toward the adjacent solar panel 22, the adjacent solar panel 22 itself does not interfere with the higher-side panel leg 26 of the solar panel 22. In addition, the lower panel leg portion 25 of the adjacent solar panel 22 can approach the higher panel leg portion 26 of the adjacent solar panel 22 without hindrance. In this case, the adjacent solar panels 22 are diagonally overlapped with one light receiving surface 23 facing obliquely upward in a state where one enters the other.

  Note that more than half of the adjacent solar panels 22 overlap each other. Specifically, if the width dimension of the solar panel 22 in the moving direction is W1, and the width dimension of the overlapping portion of the solar panels 22 is W2, the width dimension W2 is larger than half the width dimension W1. (See FIG. 2 (a)).

  In the roof portion 15, all adjacent solar panels 22 can overlap. Specifically, with respect to a pair of adjacent solar panels 22 in an overlapped state, the other solar panels 22 can be overlapped by entering further downward. Here, when all the solar panels 22 are stacked, the solar panels 22 are housed in the half area of the waterproof layer 17 as compared to the case where the solar panels 22 are arranged without overlapping. In this case, the size of the overlapping portion of the solar panels 22 in the moving direction of the solar panels 22 is based on the relationship between the area of the roof surface 15a and the total area of the light receiving surfaces 23 of all the solar panels 22. Is set.

  Incidentally, the range in which the solar panel 22 can move in the roof portion 15 corresponds to the panel movable range. The panel movable range includes a region below the solar panel 22 and a region that can be moved downward as the solar panel 22 moves. Therefore, the lower panel leg portion 25 is provided in the panel movable range, and the higher panel leg portion 26 is provided in a position not in the panel movable range.

  The lower support rail 31 and the higher support rail 32 are provided with lock portions that hold the positions of the lower panel leg 25 and the higher panel leg 26. The lock part can be shifted to a locked state and an unlocked state, and each solar panel 22 is held in a side-by-side state or in an overlapped state by being in a locked state, and each sun is in an unlocked state. The slide movement of the optical panel 22 is enabled.

  The solar panel 22 is provided with a stopper (not shown) for avoiding contact with the adjacent solar panel 22. When the solar panel 22 moves relatively toward the adjacent solar panel 22, for example, the stopper contacts the lower panel leg 25 of the adjacent solar panel 22 on the lower side of the solar panel 22, for example. In the position. In this case, when the stopper comes into contact with the lower panel leg portion 25, the distance between the adjacent solar panels 22 is held at such a size that the solar panels 22 do not come into contact with each other. Thereby, the damage of these solar panels 22 when the solar panels 22 are piled up diagonally is suppressed.

  The stopper may be provided on the lower panel leg 25 or the higher panel leg 26. In this case, contact between the solar panels 22 is ensured by securing a separation distance between the lower panel legs 25 of the adjacent solar panels 22 and a separation distance between the higher panel legs 26. Will be avoided.

  In addition, the solar panel 22 is provided with a buffer member that reduces the impact when the solar panels 22 come into contact with each other. The buffer member is formed of an impact absorbing material such as rubber, and even if the solar panels 22 come into contact with each other even though the stopper is provided, the shock due to the contact is reduced. Thereby, it can suppress that the solar panel 22 is damaged or deform | transformed. The buffer member may be provided on the high-side panel leg 26 or the low-side panel leg 25.

  The stopper and the buffer member are provided at positions that do not block sunlight irradiated on the light receiving surface 23 in the solar panel 22. Thereby, the inconvenience that the power generation efficiency of the solar panel 22 is reduced by the stopper and the buffer member is avoided.

  The lower support rail 31 and the higher support rail 32 are fixed to the roof base material 16 in a state of being separated from the waterproof layer 17. Specifically, a gantry frame 35 is installed on the waterproof layer 17 with the gantry plate 33 interposed therebetween. The gantry plate 33 is a plate portion formed of a steel material and has water-impermeable properties. The gantry frame 35 is in contact with the gantry plate 33 on the inner side of the peripheral portion of the gantry plate 33, and the contact portion and the peripheral portion of the gantry plate 33 are separated from each other. The gantry frame 35 is fixed to the roof base material 16 together with the gantry plate 33 by fixing means such as bolts.

  A plurality of gantry frames 35 are installed on the waterproof layer 17, and the support rails 31 and 32 are respectively placed on the gantry frames 35. In this case, the support rails 31 and 32 are separated from the waterproof layer 17 by the height of the gantry frame 35 and the thickness of the gantry plate 33. The support rails 31 and 32 are fixed to the gantry frame 35 by a fixing bracket or the like.

  In addition, electrical wiring is electrically connected to each solar panel 22, and the electric power generated in the solar panel 22 is sent to a power storage device or a distribution board of the building 10 through the electrical wiring. The power wiring is formed by a power cable or the like, and maintains the state where the solar panel 22 is electrically connected to the power storage device, the distribution board, etc. even if the solar panel 22 moves. For example, a power cable or the like is partially fixed on the roof portion 15, and the non-fixed portion moves with the movement of the solar panel 22. Therefore, even when the solar panel 22 is moved, if power is generated by the solar panel 22, the power can be sent to a power storage device or a distribution board.

  Next, the work procedure when performing the maintenance work on the roof will be described with reference to FIGS. 2 and 3 are diagrams showing a schematic plane of the roof portion 15 when the solar panel 22 is moved. In FIGS. 2A and 3A, the lower support rail 31 and the higher support rail 32 are not shown in order to make the first area S1 and the second area S2 easier to see. The installation position of the support rail 31 is indicated by a one-dot chain line L1, and the installation position of the higher-level support rail 32 is indicated by a one-dot chain line L2.

  When performing the maintenance work on the roof, first, the solar panel 22 is slid in the longitudinal direction of the alternate long and short dash lines L1 and L2 to secure a work space, and a new waterproof material 41 is installed in the work space on the existing waterproof layer 17. Install on top. Next, the solar panel 22 is moved to a portion where the new waterproof material 41 is attached to secure a work space in an unworked portion, and the new waterproof material 41 is placed on the upper surface of the existing waterproof layer 17 in the work space. Attach to. The waterproof material 41 is a sheet-like waterproof sheet, and the waterproof material 41 is attached to the waterproof layer 17 by welding or adhesion.

  Specifically, as shown in FIG. 2A, the roof surface 15 a is equally divided into two by the first area S <b> 1 and the second area S <b> 2, and these areas S <b> 1 and S <b> 2 are the solar panels 22. When arranged side by side in the movement direction, first, all the solar panels 22 are moved to the first area S1 so that the second area S2 becomes a work space. And as shown in FIG.2 (b), the novel waterproof material 41 is attached to the upper surface of the existing waterproof layer 17 in 2nd area S2 as a work space.

  After completing the work of attaching the waterproof material 41 in the second area S2, as shown in FIG. 3A, all the solar panels 22 are moved to the second area S2, so that the first area S1 becomes a work space. To. And as shown in FIG.3 (b), the novel waterproof material 41 is attached to the upper surface of the existing waterproof layer 17 in 1st area S1 as a work space. After the installation work of the waterproofing material 41 in both the first area S1 and the second area S2, the maintenance work of the roof and the series of work related thereto are completed by returning the solar panels 22 to the side-by-side arrangement. Become.

  In the present embodiment, a plurality of waterproof sheets are used as the waterproof material 41, and the work of attaching the waterproof sheets to the upper surface of the existing waterproof layer 17 corresponds to the work of attaching the waterproof material 41. Here, an operation procedure for attaching a plurality of waterproof sheets will be described with reference to FIG.

  FIG. 4 is a diagram for explaining a procedure for attaching the waterproof sheets 41a to 41c. 4A to 4D are enlarged plan views of the roof portion 15 around the gantry plate 33, respectively. In FIG. 4, the lower support rail 31, the higher support rail 32, and the gantry frame 35 are not shown, and the installation positions of the support rails 31 and 32 are the same as in FIGS. 2 (a) and 3 (a). Are indicated by alternate long and short dash lines L1 and L2. Furthermore, the attachment procedure of the waterproof sheets 41a to 41c is applied to both the first area S1 and the second area S2.

  Here, with respect to the existing waterproof layer 17 shown in FIG. 4A, as the waterproof material 41, a first waterproof sheet 41a that is first attached to the upper surface of the existing waterproof layer 17 and a second waterproof sheet 41b that is subsequently attached. Then, the third waterproof sheet 41c to be attached next is attached in order.

  First, as shown in FIG. 4B, the first waterproof sheet 41 a is attached to the upper surface of the waterproof layer 17. Specifically, it is attached to the upper surface of the waterproof layer 17 outside the high-level support rail 32 (installation position indicated by the alternate long and short dash line L2) and the low-order support rail 31 (installation position indicated by the alternate long and short dash line L1). The first waterproof sheet 41 a enters the lower support rail 31 side than the high support rail 32 between the gantry plates 33 below the high support rail 32. Similarly, between the gantry plates 33 below the lower support rail 31, the lower support rail 31 enters the higher support rail 32 side. Therefore, the first waterproof sheet 41 a is also attached below the support rails 31 and 32 between the gantry plates 33.

  Next, as shown in FIG. 4C, the second waterproof sheet 41 b is attached between the high-level support rail 32 and the low-level support rail 31. In this case, the second waterproof sheet 41b is placed on the waterproof layer 17 and the first waterproof sheet 41a, and is welded or bonded to the first waterproof sheet 41a.

  And as shown in FIG.4 (d), the 3rd waterproof sheet 41c is attached to the boundary part of the mount plate 33, the 1st waterproof sheet 41a, and the 2nd waterproof sheet 41b. The third waterproof sheet 41c is formed in a ring shape, and a notch 42 for cutting the ring is formed. In this case, the 3rd waterproof sheet 41c is attached so that the notch 42 may be expanded and the mount frame 35 may be located in the ring-shaped center part.

  A configuration around the waterproof layer 17 in a state where the first waterproof sheet 41a to the third waterproof sheet 41c are attached will be described with reference to FIG. FIG. 5 is a cross-sectional view of the roof portion 15 around the gantry plate 33 after the waterproofing process is completed.

  As shown in FIG. 5, the 1st waterproof sheet 41a is provided on the waterproof layer 17 which had formed the roof surface 15a. Here, the first waterproof sheet 41a has substantially the same thickness as the gantry plate 33, and the upper surface of the first waterproof sheet 41a and the upper surface of the gantry plate 33 are on the same plane. A third waterproof sheet 41c is provided on the first waterproof sheet 41a and the gantry plate 33, and a boundary portion between the first waterproof sheet 41a and the gantry plate 33 is covered from above by the third waterproof sheet 41c. . The third waterproof sheet 41 c is disposed outside the gantry frame 35, and the end of the third waterproof sheet 41 c is in contact with the peripheral edge of the gantry frame 35.

  In addition, in the part where the 2nd waterproof sheet 41b is directly attached on the waterproof layer 17 between the high level side support rail 32 and the low level side support rail 31, the boundary of the 2nd waterproof sheet 41b and the mount plate 33 The portion is covered from above by the third waterproof sheet 41c.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  A plurality of solar panels 22 are slidable in a direction overlapping each other on the roof portion 15. Here, in the roof portion 15 set by dividing the roof surface 15a into the first area S1 and the second area S2, the second area S2 is made solar by moving all the solar panels 22 to the first area S1. A space without the optical panel 22 can be provided. Therefore, when attaching the new waterproof material 41 to the upper surface of the existing waterproof layer 17, the second area S2 can be used as a work space. Similarly, the first area S1 can be used as a work space by moving all the solar panels 22 to the second area S2. Thereby, compared with the case where the narrow space between the roof surface 15a and the solar panel 22 is used as a work space, the attachment work of the waterproof material 41 can be facilitated. Moreover, compared with the case where the operation | work which removes the solar panel 22 with heavy machines, such as a crane, and the operation | work which reinstalls in order to ensure work space, work can be facilitated and cost reduction can be achieved.

  As a result, a series of operations such as a roof maintenance operation and a preparation operation related thereto can be facilitated.

  Since all the solar panels 22 can be moved to either the first area S1 or the second area S2 in the roof portion 15, the work for attaching the new waterproof material 41 is the same as the first area S1 and the first area S1. This can be done twice with the two areas S2. That is, the number of times of moving the solar panel 22 can be reduced as much as possible. Thereby, in the maintenance work called waterproofing of a roof, the preparation work can be facilitated.

  In the moving direction of the solar panels 22, since the higher end of one solar panel 22 is adjacent to the lower side of the other solar panel 22, the other solar panel 22 is adjacent. The solar panels 22 can be overlapped by relatively moving 22 so as to enter the lower side of the one solar panel 22.

  Since the high-side panel leg portion 26 is erected away from the solar panel 22 in a direction orthogonal to the moving direction of the solar panel 22, that is, provided at a position that is not the panel movable range, When one of the adjacent solar panels 22 enters the lower side of the other, the lower solar panel 22 can be prevented from coming into contact with the higher panel leg portion 26 of the upper solar panel 22. Therefore, the lower solar panel 22 can enter the tip side (lower panel leg 25 side) of the upper solar panel 22 relative to the higher panel leg 26.

  On the other hand, in the configuration in which the high-side panel leg 26 is provided below the solar panel 22, the lower solar panel 22 hits the high-side panel leg 26 of the upper solar panel 22, and the upper side No further can enter the lower side of the solar panel 22. Therefore, the amount of overlapping of the solar panels 22 can be increased as compared with the configuration in which the higher panel leg 26 is provided below the solar panel 22. That is, the work space secured by the movement of the solar panel 22 in the roof portion 15 can be increased.

  Since the solar panel 22 is supported by the lower panel leg 25 in addition to the higher panel leg 26, the support strength of the solar panel 22 is increased. In addition, since the lower panel leg 25 and the lower support rail 31 are provided below the solar panel 22, that is, in the panel movable range, the area that is not the panel movable range is reduced. Can do. Therefore, the installation area (panel movable range) of the solar panel 22 can be increased in the roof portion 15, and thus the amount of electric power by solar power generation can be increased.

  For the solar panel 22, a high-side support rail 32 that guides the moving direction of the high-side panel leg 26 and a low-side support rail 31 that guides the moving direction of the low-side panel leg 25 are individually provided. Therefore, when one of the adjacent solar panels 22 enters the lower side of the other, the lower panel leg 25 of the lower solar panel 22 and the higher panel leg 26 of the upper solar panel 22 Can be avoided. Therefore, the lower panel leg 25 of the lower solar panel 22 can enter the lower panel leg 25 side of the upper solar panel 22 with respect to the upper panel leg 26.

  On the other hand, in the configuration in which the high-level support rail 32 and the low-level support rail 31 are the same rail, the low-level panel leg 25 of the lower solar panel 22 is connected to the upper solar panel 22. The lower solar panel 22 cannot hit the lower side of the upper solar panel 22 when it hits the higher panel leg 26. Therefore, compared with the structure by which the high-order side support rail 32 and the low-order side support rail 31 become the same rail, the quantity which the solar panels 22 overlap can be enlarged.

  In the configuration in which the lower panel leg 25 is provided below the solar panel 22, the lower panel leg 25 is provided at the lower end of the solar panel 22. Therefore, when one of the adjacent solar panels 22 enters the lower side of the other, the lower solar panel 22 can enter until it hits the lower panel leg portion 25 of the upper solar panel 22. That is, the amount of overlapping of the solar panels 22 can be increased as compared with the configuration in which the lower panel leg 25 is provided on the higher side than the lower end.

  About the solar panel 22, since the high-order side panel leg part 26 is arrange | positioned to the side of the solar panel 22, and the low-order side panel leg part 25 is arrange | positioned under the solar panel 22, with the high-order side support rail 32, The lower support rail 31 can be separated. Therefore, a space for attaching a new waterproof material 41 can be formed between the high-side support rail 32 and the low-side support rail 31. Therefore, it is possible to facilitate the waterproofing work between the support rails 31 and 32.

  A gantry frame 35 that fixes the high-side support rail 32 and the low-side support rail 31 is placed on the existing waterproof layer 17 with the gantry plate 33 interposed therebetween, and the periphery of the gantry plate 33 is connected to the gantry frame 35. It is outside the contact part. In this case, the third waterproof sheet 41c is attached on the first and second waterproof sheets 41a and 41b attached to the periphery of the gantry plate 33 so as to span the gantry plate 33, Waterproofing can be performed so that the waterproof performance at the peripheral edge of the gantry plate 33 does not deteriorate. That is, the waterproofing process can be performed so that the waterproof performance does not deteriorate at the support portions of the support rails 31 and 32.

  Since the solar panel 22 can be moved while being electrically connected to a power storage device, a distribution board, etc., the solar panel 22 generates power while performing maintenance work on the roof, and further uses the power. It can be sent to a power storage device or a distribution board.

The present invention is not limited to the description of the above embodiment, and may be implemented as follows, for example.

  (1) The solar panel 22 may be provided such that the light receiving surface 23 faces directly above. In this case, it is preferable that the plurality of solar panels 22 are installed such that the heights of the respective light receiving surfaces 23 are different. That is, it is preferable that the solar panels 22 are installed so as to be able to overlap each other. Thereby, with the movement of the solar panel 22, a work space for waterproofing processing can be secured on the roof surface 15a.

  (2) In the roof portion 15, the solar panels 22 may be arranged in a plurality of rows instead of one row in the movement direction.

  (3) The solar panel 22 may be configured such that the direction of the light receiving surface 23 can be adjusted. In this case, by adjusting the angle in the direction in which the solar panel 22 stands in the vertical direction, the work space that can be secured by stacking the solar panels 22 can be further increased.
