Description

The present invention relates to a fixture for a panel array including a plurality of arranged panels.

In recent years, a plurality of solar cell modules arranged in an array may be installed on a place such as a roof of a building. The solar cell module has a solar cell panel having a power generation unit and a frame that holds a peripheral end portion of the solar cell panel. The solar cell module is installed on the roof by holding a frame by a fixture fixed to the roof.

The following Patent Document 1 discloses a fixture for fixing a plurality of panel-shaped solar cell modules provided side by side on the slope of a building along the inclination direction. The fixture is arranged between the solar cell modules adjacent to each other in the tilt direction. The fixture has a lower fixture fixed to a slope of a building and an upper fixture fastened to the lower fixture. The lower fixture supports the lower surface of the solar cell module adjacent to each other on the lower side in the inclination direction. Among the solar cell modules adjacent to each other, the upper fixing tool supports the lower surface of the upper solar cell module in the inclination direction.

Japanese Patent No. 5595420

The installation surface such as the roof of a building is often not flat. Therefore, the heights of the ends of the solar cell modules adjacent to each other may vary. In the fixture described in Patent Document 1, the height between the ends of the solar cell modules adjacent to each other in the tilt direction is determined according to the structure of the fixture. Therefore, the heights of the ends of the solar cell modules adjacent to each other in the tilt direction do not vary.

However, the heights of the ends of the solar cell modules that are adjacent to each other in the lateral direction orthogonal to the tilt direction may vary. In this case, a step is generated between the solar cell modules, and the appearance of the solar cell module array is deteriorated. Therefore, it is preferable to adjust the height of at least one of the solar cell modules that are laterally adjacent to each other.

Here, the necessity of height adjustment can be determined only by once fixing the solar cell module with a fixture. This is because the heights of the solar cell modules adjacent to each other in the lateral direction cannot be compared unless the solar cell modules are fixed with a fixture.

When attempting to adjust the height of the solar cell module with the fixture described in Patent Document 1, it is necessary to insert a member such as a spacer between the installation surface and the lower fixture. Therefore, when adjusting the height of the solar cell module with the fixture described in Patent Document 1, the fixture once fixed to the installation surface is removed from the installation surface or the member that fastens the fixture to the installation surface is loosened. There is a need. Therefore, the work of adjusting the height of the solar cell module is difficult and time-consuming.

The above problem is not limited to the fixture for fixing the solar cell module array, but may occur for a fixture for a panel array in which a plurality of panels are arranged.

Therefore, a fixture for a panel array that can easily adjust the height of the panel is desired.

A fixture for a panel array according to one aspect includes a base that is fixed to an installation surface, a support member that is located on the base, and a fastening member that fastens the support member and the base to each other. The support member includes a first stacking unit that supports one of the mutually adjacent panels from below, and a second stacking unit that supports the other of the mutually adjacent panels from below. The fixing member is configured to be able to form a spacer region for installing a spacer that moves both the first loading unit and the second loading unit away from the base by loosening the fastening member.

With the fixture for a panel array according to the above aspect, the height of the panel can be easily adjusted.

Hereinafter, a panel array mounting structure and a panel array fixture according to an embodiment will be described with reference to the drawings.

FIG. 1 shows a panel array mounting structure according to an embodiment. FIG. 2 shows a state in which the panel is removed from FIG. FIG. 3 is a cross-sectional view of the panel array mounting structure taken along the direction 3A-3A in FIG. FIG. 4 is an enlarged view in which the region 4A of FIG. 3 is enlarged. The panel array is installed on an installation surface inclined from the horizontal plane. As such an installation surface, for example, a roof of a building, specifically, a roof material 210 such as a slate or a tile, and a base material 220 of a roof material such as a floor board can be cited. In addition, the ground plate includes a roof plate whose surface is subjected to roofing. In the illustrated embodiment, the panel array is installed on the base 220 of the roofing material 210.

In this specification, the direction from the higher direction to the lower direction along the maximum inclination line on the inclined installation surface is referred to as “flow direction F1”. The upstream side in the flow direction F1 is referred to as "water side". The downstream side in the flow direction F1 is referred to as "underwater side". Further, a direction orthogonal to the flow direction F1 in a plane parallel to the horizontal plane is referred to as "lateral direction F2".

The panel array mounting structure includes a plurality of panels 100A and 100B, a plurality of panel array fixtures 20O, 20A and 20B, and a plurality of covering plates 90O, 90A and 90B. The plurality of panels 100A and 100B are arranged side by side in the flow direction F1 and the lateral direction F2. The panels 100A and 100B may be, for example, solar cell modules. The respective panels 100A, 100B are installed on the installation surface by the fixtures 20O, 20A, 20B.

In the present embodiment, the fixtures 20O, 20A, 20B are provided at the water-side end and the water-side end of each panel 100A, 100B. The fixture 20A supports both the panels 100A and 100B adjacent to each other in the flow direction F1 except for the fixture 20B on the most water side and the fixture 20O on the most water side (see FIG. 4). Specifically, the fixture 20A supports the underwater end of the underwater panel 100A and the underwater end of the underwater panel 100B. Each fixture 20O, 20A, 20B is fixed to the installation surface by a fixing member 32. The fixing member 32 may be at least one of a bolt, a screw, and a nail, for example. Note that the uppermost water fixture 20B and the lowermost water fixture 20O may have the same structure as the fixture 20A that supports both the panels 100A and 100B adjacent to each other in the flow direction F1.

The plurality of covering plates 90O, 90A, 90B cover the installation surface. The covering plates 90O, 90A, 90B are made of a material that is impermeable to liquid. In the present embodiment, the covering plates 90O, 90A, 90B are made of members different from the roof material originally provided on the roof. The cover plates 90O, 90A, 90B may be, for example, sheet metal. In this case, the sizes of the covering plates 90O, 90A, 90B can be appropriately designed according to the sizes of the installed panels 100A, 100B and the positions of the fixtures 20O, 20A, 20B. Alternatively, the covering plates 90O, 90A, 90B may be roofing materials 210 that are originally provided on the roof, such as slate.

Each cover plate 90O, 90A, 90B passes between each fixture 20O, 20A, 20B and the installation surface. Each covering plate 90O, 90A, 90B is fixed to the installation surface by the fixing member 32 of each fixing tool 20O, 20A, 20B. In order to ensure waterproofness, the fixtures 20O, 20A, 20B are installed by the fixing member 32 with the waterproof sheet 66 being arranged between the fixtures 20O, 20A, 20B and the covering plates 90O, 90A, 90B. It is fixed to the surface. This prevents water from penetrating the installation surface along the fixing member 32. The underwater side ends 90Aa and 90Ba of the covering plates 90A and 90B (waterside covering plates) fixed by the one fixing device 20A and 20B (waterside fixing device) are respectively the waterside fixing devices. It covers a part of the covering plates 90O, 90A (underwater covering plate) fixed by the fixing devices 20O, 20A (underwater fixing device) located on the underwater side of 20A, 20B (FIG. 3). And FIG. 4).

The underwater side ends 90Aa and 90Ba of the waterside cover plates 90A and 90B are preferably in contact with the underwater fixtures 20O and 20A, respectively. The water-side end portions 90Ab of the water-side cover plates 90A and 90B extend to the water side above the fixtures 20A and 20B that fix the water-side cover plates 90A and 90B. Therefore, the length of the covering plates 90A and 90B in the flow direction F1 is longer than the length of the panels 100A and 100B in the flow direction F1.

The panels 100A, 100B, the fixtures 20O, 20A, 20B and the covering plates 90O, 90A, 90B repeat the above-described structure in the flow direction L. Therefore, of the covering plates 90O, 90A, 90B adjacent to each other in the flow direction F1, the water-side end portions 90Aa, 90Ba of the water-side covering plates 90A, 90B are above the water of the water-side covering plates 90O, 90A, respectively. It overlaps with the end portions 90Ob and 90Ab on the side. As a result, when the water flows on the covering plates 90O, 90A, 90B in the flow direction F1, the water flows from the underwater side end of the covering plates 90O, 90A, 90B onto another covering plate 90O, 90A, 90B. Will be reached. Therefore, the water flowing in the flow direction F1 can be prevented from directly adhering to the installation surface, and the waterproof structure of the installation surface is maintained.

Further, one covering plate 90O, 90A, 90B exists between each fixture 20O, 20A, 20B and the installation surface. Further, the water-side end portions 90Aa, 90Ba of the water-side cover plates 90A, 90B of the respective fixtures 20O, 20A are located on the water-side side of the fixtures 20O, 20A, or contact the fixtures 20O, 20A. Touching.

Further, it is preferable that the water side ends 90Aa and 90Ba of the covering plates 90A and 90B cover the fixing member 32 that fixes the fixing members 20O and 20A to the installation surface. As a result, when the water flows on the covering plates 90A and 90B in the flow direction F1, it becomes difficult for the water to adhere to the fixing member 32. Therefore, deterioration of the fixing member 32 such as rust can be suppressed.

It is preferable that the water-side ends 90Ob and 90Ab of the covering plates 90O, 90A and 90B have a folded-back portion 92 that is folded back to the side opposite to the installation surface. The folded portion 92 extends in the lateral direction F2 (see FIG. 5). As a result, even when water flows backward on the covering plates 90O, 90A, 90B due to the influence of wind, the reverse flow of water is blocked by the turnback portion 92. Therefore, it is possible to prevent the backward flow of water from reaching the installation surface.

The ends of the covering plates 90O, 90A, 90B in the lateral direction F2 and the end on the underwater side may be folded back if necessary.

The covering plates 90O, 90A, 90B may have a waterproof member 98 on the surface opposite to the installation surface. The waterproof member 98 is provided in a region overlapping the cover plates 90A, 90B on the water side of the cover plates 90O, 90A, 90B on which the waterproof member 98 is provided. The waterproof member 98 preferably extends in the lateral direction F2 (see FIG. 5). More preferably, the waterproof member 98 extends from one end to the other end of the covering plates 90O, 90A, 90B. Thereby, it is possible to further suppress the backflow of water to the water upper side.

In FIG. 4, there is a gap between the waterproof member 98 provided on the underwater covering plate 90A and the overwater covering plate 90B. Alternatively, the waterproof member 98 provided on the underwater covering plate 90A may be in close contact with the underwater covering plate 90B.

The waterproof member 98 is preferably made of an elastic member. Since the waterproof member 98 provided on the underwater covering plates 90O, 90A is covered with the overwater covering plates 90A, 90B, it may receive pressure from the overwater covering plates 90A, 90B. When the waterproof member 98 is made of an elastic member, the waterproof member 98 absorbs the pressure from the water-side covering plates 90A and 90B, thereby preventing deformation of the water-side covering plates 90O and 90A.

Next, the fixtures 20O, 20A, and 20B for the panel array will be described in more detail with reference to FIGS. 6 to 9. FIG. 6 is a perspective view of a fixture that supports only one panel 100A. FIG. 7 is an enlarged perspective view of the fixture in the area 7A of FIG. FIG. 8 is a side view of the fixture seen from the arrow 8A direction in FIG. 7. FIG. 9 is an exploded perspective view of the fixture excluding a third support portion 46 described later.

The fixtures 20O, 20A, 20B have a base portion 30, a fixing member 32, a supporting member 40, and a fastening member 60. The base 30 has a protrusion 36 that supports a first stacking unit 43, which will be described later, and is fixed to the installation surface by a fixing member 32. The support member 40 is located on the base 30. The fastening member 60 fastens the support member 40 and the base 30 to each other. That is, the fastening member 60 presses the support member 40 toward the base portion 30.

The support member 40 includes a first support portion 42, a second support portion 44, and a third support portion 46. The first support portion 42 has a first stacking portion 43 that supports one panel 100A, which is one of the panels adjacent to each other, from below. Further, when the first stacking unit 43 is supported by the protrusion 36, the panel 100A is supported more firmly. The second support portion 44 has a second stacking portion 45 that supports the other panel 100B of the adjacent panels from below.

The first support portion 42 is provided on the base portion 30. The second support portion 44 is provided on the first support portion 42. The third support portion 46 is provided on the first support portion 42. Alternatively, the third support portion 46 may be provided on the second support portion 44. The fastening member 60 fastens the first support portion 42, the second support portion 44, and the base portion 30 to each other.

The third support portion 46 has a side contact portion 50. The side contact portion 50 is a portion sandwiched between the side surface of the panel 100A supported by the first stacking portion 43 and the side surface of the panel 100B supported by the second stacking portion 45.

The third support portion 46 may have a first flange 52 and a second flange 54. The first flange 52 projects from the upper portion of the side surface contact portion 50 toward the first stacking portion 43 side. The second flange 54 projects from the upper portion of the side surface abutting portion 50 toward the second stacking portion 45 side. In the present embodiment, the water-side ends of the panels 100A and 100B are supported by the first stacking unit 43 and the first flange 52. Further, the water side ends of the panels 100A and 100B are supported by the second stacking unit 45 and the second flange 54. Further, a snow stopper 56 protruding upward from the first flange 52 or the second flange 54 may be provided.

The third support portion 46 may extend along one direction. In the present embodiment, the side surface abutting portion 50 extends along the lateral direction F2, that is, the direction intersecting the flow direction F1. The side contact portion 50 preferably has a length substantially the same as the length of the panels 100A and 100B in the lateral direction F2. More specifically, the difference between the length of the side surface contact portion 50 and the length of the panels 100A and 100B in the lateral direction F2 may be preferably less than 10 mm, more preferably less than 5 mm, and even more preferably less than 2 mm. As a result, the fixtures 20O, 20A, 20B can cover the side surfaces of the panels 100A, 100B along the lateral direction F2 almost entirely or completely. Thereby, the appearance of the panel array can be improved.

As shown in FIG. 6, the third support portion 46 may be shared by a plurality of base portions 30. Further, although not shown, the first support portion 42 and the second support portion 44 may extend in the lateral direction F2 similarly to the side surface contact portion 50. However, as shown in FIG. 6, it is preferable that the first support portion 42 and the second support portion 44 are provided corresponding to the base portion 30, respectively. That is, the first support portion 42, the second support portion 44, and the base portion 30 do not have to extend long in one direction like the third support portion 46. This makes it possible to reduce the area other than the area that easily affects the appearance of the panel array mounting structure. Therefore, the material required for the fixtures 20O, 20A, 20B can be reduced.

The base portion 30 is preferably configured to be slidable along the side surface contact portion 50 extending in one direction. As a result, the position where the fixing member 32 is attached can be aligned with the predetermined position on the installation surface. In the present embodiment, the first support portion 42, the second support portion 44, and the base portion 30 are configured to be slidable along the side surface contact portion 50.

As a specific example, the second support portion 44 has an engagement portion 44a, and the third support portion 46 has an engagement portion 46a. As an example, it is preferable that the engagement portion 46a of the third support portion 46 has the same cross-sectional shape at any position in the sliding direction at least within the slidable section (see FIG. 7). Accordingly, the engagement portion 44a of the second support portion 44 is slidably engaged with the engagement portion 46a of the third support portion 46. The second support portion 44 and the base portion 30 are configured to be slidable along the third support portion 46 by being fastened to each other by the fastening member 60. More specifically, the first support portion 42, the second support portion 44, and the base portion 30 are configured to be slidable along the third support portion 46 by being fastened to each other by the fastening member 60.

The second support portion 44 and the third support portion 46 may be engaged with each other on the second stacking portion 45 side with respect to the side surface contact portion 50. In this case, it is preferable that the engagement portion 44a of the second support portion 44 be located above the engagement portion 46a of the third support portion 46. Accordingly, when the panel 100B stacked on the second stacking unit 45 presses the side surface abutting unit 50 toward the first stacking unit 43 side, the second supporting unit 44 and the third supporting unit 46 are more strongly engaged with each other. To do. Such fixtures 20O, 20A, and 20B are suitable for installing the first stacking unit 43 facing the underwater side and the second stacking unit 45 facing the waterside.

In the present embodiment, the first support portion 42, the second support portion 44, and the third support portion 46 are composed of different members. Alternatively, at least two of the first support portion 42, the second support portion 44, and the third support portion 46 may be formed of an integral member. For example, the first support portion 42 and the third support portion 46 may be formed as an integral member. In this case, it is preferable that the second support portion 44 and the base portion 30 are configured to be slidable together along the side surface contact portion 50. In order to realize such a configuration, for example, a hole for passing the fastening member 60 formed in the first support portion 42 may be extended along the side surface contact portion 50.

The fixing member 32 that fixes the base 30 to the installation surface is preferably located below the panel 100</b>B loaded on the second loading unit 45. In other words, the fixing member 32 that fixes the base 30 to the installation surface is preferably provided closer to the second stacking unit 45 side than the side surface abutting unit 50. In this case, the base 30 of the fixtures 20O, 20A, 20B can be fixed to the installation surface by the fixing member 32 while the panel 100A is supported by the first stacking unit 43.

The base portion 30 may have an abutment surface 34 that abuts the underwater end portions 90Aa, 90Ba of the covering plates 90O, 90A, 90B. The contact surface 34 is preferably provided closer to the first stacking unit 43 side than the fixing member 32. As described above, when one fixture 20O, 20A has a plurality of bases 30 in the lateral direction F2, the covering plates 90A, 90B are in contact with the respective contact surfaces 34 of the plurality of bases 30. More preferable. Further, when one fixture 20O, 20A has a plurality of bases 30 in the lateral direction F2, the covering plates 90A, 90B cover a plurality of fixing members 32 that fix each of the plurality of bases 30 to the installation surface. It is preferable.

FIG. 10 is a side view of the fixtures 20O, 20A, 20B with the fastening member 60 loosened. FIG. 11 is a side view of the fixture in which the spacer 70 is installed. As shown in FIG. 10, by loosening the fastening member 60, the pressing of the support member 40 against the base portion 30 is released. Thereby, a space can be provided between the base 30 and the support member 40. This space defines a spacer area S in which the spacer 70 is installed. The spacer 70 can move both the first loading section 43 and the second loading section 45 upward with respect to the base section 30. Thereby, the heights of both the panels 100A and 100B adjacent to each other can be increased by the same level.

More specifically, the first support portion 42 is provided on the base portion 30, and the second support portion 44 and the third support portion 46 are provided on the first support portion 42. The spacer region S is formed between the first support portion 42 and the base portion 30. With such a configuration, the heights of the first support portion 42, the second support portion 44, and the third support portion 46 can be accurately adjusted only by installing the spacer 70 between the first support portion 42 and the base portion 30. Can be raised by the same level.

The spacer region S can be formed by loosening the fastening member 60 without loosening or removing the fixing member 32. That is, the height of the panel 100A using the spacer 70 can be adjusted with the base 30 fixed to the installation surface. Therefore, the work of height adjustment is easy, and the labor of the worker can be reduced. Note that when the spacer 70 is installed, not only the fastening member 60 may be loosened, but the fastening member 60 may be completely removed.

Further, since it is not necessary to loosen or remove the fixing member 32 fixed to the installation surface, the pull-out strength of the fixtures 20O, 20A, 20B from the installation surface is reduced, or the fixing member 32 opens the installation surface to the installation surface. It is possible to prevent water such as rain from entering through the formed holes.

The spacer region S preferably extends from below the panel 100A supported by the first stacking unit 43 to below the panel 100B supported by the second stacking unit 45. More specifically, the spacer region S extends from a region closer to the first stacking unit 43 than the side face abutting unit 50 to a region closer to the second stacking unit 45 than the side face abutting unit 50. Thereby, the spacer 70 can be located directly under both of the panels 100A and 100B adjacent to each other. Therefore, even when the spacer 70 is used, the bias of the load applied to the support member 40 can be suppressed, and thus the support member 40 can stably support both the panels 100A and 100B adjacent to each other. it can.

The fastening member 60 is preferably located below the panel 100B supported by the second stacking unit 45. In other words, the fastening member 60 is located at least on the second stacking unit 45 side with respect to the side surface abutting unit 50. In this case, even when only one panel 100A is supported by the first stacking unit 43, the fastening member 60 is exposed without being covered by the panel 100A. Therefore, the height of the panel 100A can be adjusted with one panel 100A being supported.

More specifically, when one panel 100A is supported by the first stacking section 43 of the fixtures 20O, 20A, 20B, the worker can move sideways without the second stacking section 45 supporting the other panel 100B. The heights of the ends of the panels 100A adjacent to each other in the direction F1 can be compared. Thereby, the worker can determine whether or not the height of the panel 100A needs to be adjusted. When height adjustment is necessary, the worker can loosen the fastening member 60 and insert the spacer 70 in the spacer region S without removing the panel 100A supported by the first stacking unit 43. As described above, since it is not necessary to remove the panel 100A once installed for height adjustment, the height adjustment work can be facilitated.

FIG. 12 is a plan view showing an example of the spacer 70. For reference, FIG. 12 shows the position of the fastening member 60 with respect to the spacer 70 when the spacer 70 is installed on the fixtures 20O, 20A, and 20B by a dotted line. It is preferable that the spacer 70 has a notch 72 that linearly extends from one end of the spacer 70. The notch 72 may have a width wider than the diameter of the fastening member 60. In this case, the spacer 70 can be inserted into the spacer region S from a direction parallel to the installation surface so that the fastening member 60 passes through the notch 72 of the spacer 70. Thereby, the spacer 70 can be installed on the fixtures 20O, 20A, and 20B only by loosening the fastening member 60 without removing the fastening member 60. Further, since the spacer 70 surrounds the fastening member 60 in a U-shape, it is possible to prevent the spacer 70 from being displaced.

The surfaces facing each other across the spacer region S, that is, both the upper surface of the base portion 30 and the lower surface of the first support portion 42 may be flat. In this case, the spacer 70 can be easily inserted into the spacer region S from the direction parallel to the installation surface.

The thickness of the spacer 70, more specifically the thickness of the insertion portion of the spacer 70, may be in the range of 1 mm to 2 mm, for example. If necessary, a plurality of spacers 70 stacked on each other may be inserted in the spacer region S.

The shape of the spacer shown in FIG. 12 is an example, and the spacer 70 may have any shape as long as it can be installed in the spacer region S. For example, the spacer 70 may be composed of a plate having no notch 72. Note that a plurality of spacers 70 may be arranged in the spacer region S side by side.

(Panel array installation method)
Next, an example of a method for installing the panel array will be described with reference to FIGS. In this example, the panel array is installed on a sloping installation surface, such as the roof of a building or the base of a roof.

First, preferably, the roofing material such as slate or roof tile is removed in the area where the panel array is to be installed (step S1). As a result, the base 220 of a roofing material such as a base plate is exposed. Furthermore, the cover plate 90O closest to the underwater side is optionally installed in the exposed underwater region of the base. The underwater covering plate 90O may have the above-mentioned configuration, but the underwater end of the underwater covering plate 90O is inserted under the roof material 210 such as a slate or a tile. Preferably.

Next, the fixture 20O closest to the bottom of the water in the area where the panel array is installed is fixed to the installation surface (step S2). The submerged fixture 20O is fixed to the base 220 of the roof material by the fixing member 32 via the cover plate 90O on the submerged side. It is preferable that the fixture 20O on the most underwater side is installed so that the second stacking unit 45 described above faces the above water side.

Next, the underwater covering plate 90A is installed on the underwater side of the undermost fixture 20O (step S3). The underwater covering plate 90A is arranged such that the underwater end portion 90Aa of the underwater covering plate 90A overlaps with the overwater end portion 90Ob of the underwater covering plate 90O. Further, it is preferable that the underwater covering plate 90A is arranged so as to abut on the abutting surface 34 of the most underwater fixture 20O. As a result, it is possible to prevent the underwater covering plate 90A from slipping off the installation surface and to position the underwater covering plate 90A. Note that FIG. 13 shows the vicinity of the water-side end portion 90Ab of the water-side covering plate 90A.

As described above, one end of the underwater covering plate 90A may have the folded portion 92. In this case, it is preferable that the underwater covering plate 90A is installed on the installation surface so that the folded-back portion 92 faces the installation surface on the side opposite to the installation surface.

The underwater covering plate 90A may have a waterproof member 98 extending in one direction. In this case, the underwater covering plate 90A has the waterproof member 98 located above the underwater fixture 20A for fixing the underwater covering plate 90A in a later step, and the waterproof member 98. Is preferably installed on the installation surface so that extends in the direction intersecting with the flow direction F1.

Next, the second loading section 45 of the fixture 20O closest to the underwater side is made to support the underwater side end of the underwater panel 100A (step S4).

Next, as shown in FIG. 14, the water side end of the water side panel 100A is supported on the first stacking portion 43 of the water side fixture 20A (step S5). At this time, the submerged fixture 20A may not yet be fixed to the installation surface. Specifically, the water-side end of the water-side panel 100A is sandwiched between the first flange 52 and the first loading portion 43 of the water-side fixture 20A.

Next, the base 30 of the submerged fixture 20A is fixed to a predetermined position of the base 220 of the roof material by the fixing member 32 (step S6). When the fixture 20A on the underwater side has a plurality of bases 30, each base 30 may be fixed to the base 220. At this time, the base portion 30 is preferably installed on the base 220 of the roof material via the underwater covering plate 90A. That is, the fixing member 32 is fixed to the base 220 through the base 30 and the cover plate 90A.

Moreover, in step S6, it is preferable to position the base 30 at a predetermined position on the installation surface in the lateral direction F2 immediately before the base 30 is fixed by the fixing member 32. The positioning of the base 30 can be performed by sliding the base 30 along the side contact portion 50.

On an installation surface such as a roof of a building, there may be a relatively high strength portion and a relatively low strength portion. For example, the fixture 20A can be firmly fixed by attaching the fixing member 32 to the position of the rafter 222 provided under the base 220 such as a field board. Here, a plurality of rafters 222 extend along the flow direction F1 of the roof, and are provided in plural in the lateral direction F2 of the roof with intervals. Therefore, it is preferable to position the base portion 30 so that the fixing member 32 can reach the rafter 222.

As described above, it is preferable that the position of the base 30 to which the fixing member 32 is attached is located below the panel 100B installed in the second stacking unit 45. In this case, even if the panel 100A is installed on the first stacking unit 43 of the fixture 20A, the base 30 can be fixed to the installation surface by the fixing member 32 without removing the panel 100A.

Next, it is judged whether or not the height adjustment of the submerged panel 100A is necessary (step S7). The necessity of adjusting the height of the submerged panel 100A can be performed by comparing the heights of the panels 100A adjacent to each other in the lateral direction F2.

When it is necessary to adjust the height of the underwater panel 100A, as shown in FIG. 15, the spacer 70 is installed in the spacer region S of the underwater fixture 20A (step S8). Specifically, by removing or loosening the fastening member 60, the above-described spacer region S is formed in the underwater fixture 20A. Then, the spacer 70 is installed in the spacer region S. As a result, the height of the water side end of the water side panel 100A can be increased.

Next, as shown in FIG. 16, the cover plate 90B on the water side is installed on the water side of the fixture 20A on the water side (step S9). The water-side covering plate 90B is arranged such that the underwater side end portion 90Ba of the water-side covering plate 90B overlaps the waterside end portion 90Ab of the underwater side covering plate 90A. Here, the underwater end portion 90Ba of the water-side covering plate 90B covers the folded portion 92 and the waterproof member 98 of the water-side covering plate 90A. Further, it is preferable that the water-side cover plate 90B is arranged so as to contact the contact surface 34 of the water-side fixture 20A. As a result, it is possible to prevent the cover plate 90B on the water side from slipping off from the installation surface and to position the cover plate 90B on the water side. More preferably, the water-side cover plate 90B is installed so as to cover the fixing member 32 that fixes the water-side fixture 20A. Note that this step S9 may be performed before step S8.

Next, the underwater end of the underwater panel 100B is supported on the second stacking portion 45 of the underwater fixture 20A (step S10). Specifically, the water side end of the water side panel 100B is sandwiched between the second flange 54 and the second stacking portion 45 of the water side fixture 20A.

Next, the water-side end of the water-side panel 100B is supported on the first stacking portion 43 of the water-side fixture 20B, and the water-side fixture 20B is covered with the roof plate through the water-side cover plate 90B. The base 220 is fixed. Thus, steps S5 to S10 are repeated according to the number of panels arranged in the flow direction F1. By fixing the fixture 20B on the uppermost water side to the base 220 of the roof material via the covering plate 90B, all the panels constituting the panel array are installed on the installation surface.
