以下、図面を参照しながら本発明の実施形態について詳しく説明する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
図１は、屋根３００の上に設置された太陽電池モジュールアレイ１００と本発明の一実施形態に係る水切り板２００を示す。説明の便宜上、図中に示されるようにＸＹＺ軸を定める。Ｙ軸は、屋根３００の傾斜に平行な方向であり、＋Ｙ方向が屋根の低い側、即ち軒側を示し、−Ｙ方向が屋根の高い側を示す。Ｘ軸は、屋根３００の傾斜に垂直な方向である。Ｚ軸は、鉛直方向、又は屋根３００の面に垂直な方向である。 FIG. 1 shows a solar cell module array 100 installed on a roof 300 and a draining plate 200 according to an embodiment of the present invention. For convenience of explanation, XYZ axes are defined as shown in the figure. The Y axis is a direction parallel to the inclination of the roof 300, and the + Y direction indicates the lower side of the roof, that is, the eaves side, and the -Y direction indicates the higher side of the roof. The X axis is a direction perpendicular to the inclination of the roof 300. The Z axis is a vertical direction or a direction perpendicular to the surface of the roof 300.
太陽電池モジュールアレイ１００は、個々の太陽電池モジュール１２０をＸ方向及びＹ方向にそれぞれ複数並べて配置したものである。太陽電池モジュール１２０は、太陽電池パネル１２２とフレーム１２４を含む。太陽電池パネル１２２は、例えば、ＣＩＳ系、ＣＩＧＳ系、単結晶シリコン系、薄膜シリコン系、有機半導体系など、様々な構造のものを適用することができる。フレーム１２４は、太陽電池パネル１２２の矩形の外周を取り囲んで太陽電池パネル１２２を保持する、例えばアルミ等の金属からなる枠材である。図１ではＸ、Ｙ方向にそれぞれ３つ、合計９個の太陽電池モジュール１２０が並べられているが、太陽電池モジュール１２０の数はこれより多くてもよいし、少なくてもよい。 The solar cell module array 100 has a plurality of individual solar cell modules 120 arranged in the X direction and the Y direction. The solar cell module 120 includes a solar cell panel 122 and a frame 124. As the solar cell panel 122, for example, panels having various structures such as a CIS system, a CIGS system, a single crystal silicon system, a thin film silicon system, and an organic semiconductor system can be applied. The frame 124 is a frame member made of a metal such as aluminum that surrounds the rectangular outer periphery of the solar cell panel 122 and holds the solar cell panel 122. In FIG. 1, nine solar cell modules 120 in total, three in the X and Y directions, are arranged, but the number of solar cell modules 120 may be larger or smaller.
太陽電池モジュール１２０は、フレーム１２４を介して屋根３００に取り付けられている。屋根３００の表面には、太陽電池モジュール１２０を固定するための縦桟（架台）３１０が備え付けられている。縦桟３１０は、最上段（屋根３００の一番高い側）の太陽電池モジュール１２０の上端位置から最下段（屋根３００の一番低い側）の太陽電池モジュール１２０の下端位置までにわたって、Ｙ方向に延在している。図１の例では、Ｙ方向に並んだ３つの太陽電池モジュール１２０を、２本の縦桟３１０が支える構造となっている。各太陽電池モジュール１２０のフレーム１２４と縦桟３１０には、互いに対応する箇所に不図示の取付部がそれぞれ設けられており、両者の取付部を例えばボルトとナットで締結することによって、太陽電池モジュール１２０が縦桟３１０に固定される。 The solar cell module 120 is attached to the roof 300 via the frame 124. On the surface of the roof 300, a vertical beam (frame) 310 for fixing the solar cell module 120 is provided. The vertical beam 310 extends in the Y direction from the upper end position of the solar cell module 120 on the uppermost stage (the highest side of the roof 300) to the lower end position of the solar cell module 120 on the lowermost stage (the lowest side of the roof 300). It is extended. In the example of FIG. 1, two vertical bars 310 support three solar cell modules 120 arranged in the Y direction. The frame 124 and the vertical beam 310 of each solar cell module 120 are provided with attachment portions (not shown) at locations corresponding to each other, and the solar cell modules are fastened by, for example, bolts and nuts. 120 is fixed to the vertical beam 310.
最下段の太陽電池モジュール１２０の更に軒側（＋Ｙ側）には、本発明の一実施形態に係る水切り板２００が設置される。水切り板２００は、金属や樹脂からなる板材に複数の貫通孔２０５を有して構成されている。板材は、横方向（Ｘ軸方向）に長い形状を有する。貫通孔２０５は、板材の長手方向であるＸ軸方向に沿って複数並んで設けられているが、太陽電池モジュール１２０の繋ぎ目（縦目地）に対向する部分２１０には、貫通孔が設けられていない。この部分２１０は、後述するように太陽電池モジュールアレイ１００の表面から流れ落ちる水を受け止める水受け部２１０として働く。貫通孔２０５は更に、板材の短手方向に複数列設けられてもよい。図１では２列の貫通孔２０５が描かれている。このように縦横に網目状に配列された複数の貫通孔２０５は、後述するように、水切り板２００の板面上を伝わって流れる水を屋根３００の側へ分散して流下させる散水部２３０を形成する。 On the eaves side (+ Y side) of the lowermost solar cell module 120, a draining plate 200 according to an embodiment of the present invention is installed. The draining plate 200 has a plurality of through holes 205 in a plate material made of metal or resin. The plate material has a shape that is long in the lateral direction (X-axis direction). A plurality of through-holes 205 are provided side by side along the X-axis direction, which is the longitudinal direction of the plate material, but a through-hole is provided in the portion 210 facing the joint (vertical joint) of the solar cell module 120. Not. As will be described later, this portion 210 serves as a water receiving portion 210 that receives water flowing from the surface of the solar cell module array 100. The through holes 205 may be further provided in a plurality of rows in the short direction of the plate material. In FIG. 1, two rows of through holes 205 are depicted. As described later, the plurality of through-holes 205 arranged vertically and horizontally in this manner in the plurality of through holes 205 disperse water flowing through the surface of the draining plate 200 and flowing down to the roof 300 side. Form.
水切り板２００の板材は、軒側に向かって凸となるように湾曲した形状を有する。そのため、水切り板２００の太陽電池モジュールアレイ１００と対向する面には、長手方向（Ｘ軸方向）に連続して延びる窪み２６０が形作られている。図１に示される水切り板２００では、板材は滑らかに湾曲して、窪み２６０の内面は滑らかな曲面となっている。あるいはまた、一枚の平らな板材を鈍角に数回折り曲げたものを水切り板２００の板材とし、窪み２６０の内面が、長手方向にわたって平坦ないくつかの平面からなる構成としてもよい。 The plate material of the draining plate 200 has a curved shape so as to be convex toward the eaves side. Therefore, a recess 260 extending continuously in the longitudinal direction (X-axis direction) is formed on the surface of the draining plate 200 facing the solar cell module array 100. In the draining plate 200 shown in FIG. 1, the plate material is smoothly curved, and the inner surface of the recess 260 is a smooth curved surface. Alternatively, a flat plate material that is bent several times at an obtuse angle may be used as the plate material of the draining plate 200, and the inner surface of the recess 260 may be composed of several flat surfaces in the longitudinal direction.
図２は、水切り板２００を太陽電池モジュールアレイ１００側から見た俯瞰図と、側面図を示す。上述したように、水受け部２１０は、貫通孔を有しない板面である。水切り板２００は、この水受け部２１０が太陽電池モジュールアレイ１００の縦目地の軒側下方にくるように位置合わせされて、取付部２７０を介して（例えばボルトとナットによって）縦桟３１０に取付固定される。水受け部２１０の横（水切り板２００の長手方向側）には散水部２３０が設けられ、散水部２３０には網目状に複数の貫通孔２０５が形成されている。水切り板２００は、太陽電池モジュールアレイ１００の側に窪み２６０を有するように、軒側が凸に湾曲している。 FIG. 2 shows an overhead view and a side view of the draining plate 200 viewed from the solar cell module array 100 side. As described above, the water receiver 210 is a plate surface that does not have a through hole. The draining plate 200 is aligned so that the water receiving portion 210 is located below the eaves side of the vertical joint of the solar cell module array 100, and is attached to the vertical rail 310 via the attachment portion 270 (for example, by bolts and nuts). Fixed. A water sprinkling portion 230 is provided beside the water receiving portion 210 (on the longitudinal direction side of the draining plate 200), and a plurality of through holes 205 are formed in the water sprinkling portion 230 in a mesh shape. The draining board 200 has a convex curve on the eaves side so as to have a depression 260 on the solar cell module array 100 side.
図３は、屋根３００に設置された太陽電池モジュールアレイ１００と水切り板２００を側面から見た様子を示す。屋根３００の表面には固定台座３２０が設けられ、この固定台座３２０に縦桟３１０が備え付けられている。上述したように、太陽電池モジュール１２０（フレーム１２４）は縦桟３１０に対して固定されている。また縦桟３１０の軒側（＋Ｙ方向側）の先端には、水切り板２００が取付部２７０（図３では不図示）を介して取り付けられている。なお、図４に示されるように、縦桟３１０の軒側の端部と水切り板２００を覆い隠すために、化粧用のスタートカバー（軒先カバーとも称する）４００を水切り板２００の上から縦桟３１０に取り付けた構成としてもよい。また、水切り板２００は、縦桟３１０ではなく、太陽電池モジュール１２０やスタートカバー４００に取り付けた構成としてもよい。 FIG. 3 shows the solar cell module array 100 and the draining plate 200 installed on the roof 300 as viewed from the side. A fixed pedestal 320 is provided on the surface of the roof 300, and a vertical rail 310 is provided on the fixed pedestal 320. As described above, the solar cell module 120 (frame 124) is fixed to the vertical beam 310. Further, a draining plate 200 is attached to the front end of the eaves side (+ Y direction side) of the vertical beam 310 via an attachment portion 270 (not shown in FIG. 3). As shown in FIG. 4, a cosmetic start cover (also referred to as an eaves edge cover) 400 is placed from above the draining plate 200 to cover the eaves-side end of the vertical beam 310 and the draining plate 200. It is good also as a structure attached to 310. FIG. Further, the draining plate 200 may be attached to the solar cell module 120 or the start cover 400 instead of the vertical rail 310.
以上のように構成された水切り板２００を太陽電池モジュールアレイ１００の軒側に設置することによる作用を説明する。図１に示されるように、太陽電池モジュールアレイ１００上に降った雨は、太陽電池モジュールアレイ１００の表面を屋根３００の傾斜に沿って下方へ流れ（矢印Ｒ１）、横目地を伝って（矢印Ｒ２）縦目地へ集まってくる（矢印Ｒ３）。こうして、図３の点線矢印に示されるように、最下段の太陽電池モジュール１２０間の縦目地からは、集められた多量の雨水が流れ落ちて、水切り板２００の水受け部２１０に当たる。水切り板２００は横方向（Ｘ軸方向）に延びた窪み２６０を有しているので、水受け部２１０に当たった雨水は、図１に示されるように、窪み２６０の延在方向（Ｘ軸方向）に沿って散水部２３０へ導かれ（矢印Ｒ４）、散水部２３０の網目状の複数の貫通孔２０５を通して屋根３００の上へと流下する（矢印Ｒ５）。このように、太陽電池モジュールアレイ１００の縦目地から集中的に流れ落ちた雨水は、水切り板２００の散水部２３０によって広範囲に屋根３００上へ散水される。その結果、雨水は屋根３００上を拡散して流れるので、水垂れ痕のムラを抑制することができる。 The effect | action by installing the draining board 200 comprised as mentioned above in the eaves side of the solar cell module array 100 is demonstrated. As shown in FIG. 1, rain that falls on the solar cell module array 100 flows downward along the slope of the roof 300 (arrow R1) on the surface of the solar cell module array 100 and travels along the horizontal joint (arrow). R2) gather at the vertical joint (arrow R3). Thus, as shown by the dotted arrow in FIG. 3, a large amount of collected rainwater flows down from the vertical joint between the lowermost solar cell modules 120 and hits the water receiving part 210 of the draining plate 200. Since the draining plate 200 has a recess 260 extending in the lateral direction (X-axis direction), the rain water hitting the water receiving portion 210 is extended in the extension direction (X-axis) as shown in FIG. Direction) to the sprinkler 230 (arrow R4) and flow down onto the roof 300 through the plurality of mesh-like through holes 205 of the sprinkler 230 (arrow R5). In this way, rainwater that has flowed intensively from the vertical joints of the solar cell module array 100 is sprayed over the roof 300 over a wide area by the sprinkler 230 of the draining plate 200. As a result, rainwater diffuses and flows on the roof 300, so that unevenness of dripping marks can be suppressed.
図５は、本発明の実施形態に係る水切り板２００における散水部２３０のバリエーションを示す。図５（Ａ）において、散水部２３０Ａは、同サイズで等間隔に並んだ複数の貫通孔２０５を有する。図５（Ｂ）では、散水部２３０Ｂの複数の貫通孔２０５は等間隔に配置されているが、各貫通孔２０５のサイズ（開口面積）は、水受け部２１０に近いほど小さく、水受け部２１０から遠いほど大きくなっている。また図５（Ｃ）では、散水部２３０Ｃの複数の貫通孔２０５は全て同じサイズを有しているが、水受け部２１０に近いほど間隔が疎らに、水受け部２１０から遠いほど間隔が密に配置されている。散水部２３０Ｂ及び２３０Ｃのいずれにおいても、水受け部２１０に近く水量の多い場所では雨水が水切り板２００を通り抜けにくく、水受け部２１０から遠く水量の少ない場所では雨水が水切り板２００を通り抜けやすい。したがって、図５（Ｂ）及び（Ｃ）の各水切り板２００は、それぞれの散水部２３０Ｂ、２３０Ｃから屋根３００の上へ雨水をより均一に散水することができ、それにより、効果的に水垂れ痕のムラを抑制することができる。 FIG. 5 shows a variation of the watering part 230 in the draining board 200 according to the embodiment of the present invention. In FIG. 5A, the water sprinkling part 230A has a plurality of through holes 205 that are the same size and are arranged at equal intervals. In FIG. 5B, the plurality of through holes 205 of the water sprinkling unit 230B are arranged at equal intervals, but the size (opening area) of each through hole 205 is smaller as the water receiving unit 210 is closer to the water receiving unit. The distance from 210 increases. In FIG. 5C, the plurality of through holes 205 of the water sprinkling unit 230C all have the same size, but the closer the water receiving unit 210 is, the smaller the interval is, and the farther the water receiving unit 210 is, the closer the interval is. Is arranged. In any of the water sprinkling units 230B and 230C, rainwater is unlikely to pass through the draining plate 200 at a location near the water receiving portion 210 and has a large amount of water, and rainwater is likely to pass through the draining plate 200 at a location far from the water receiving portion 210 and having a small amount of water. Therefore, each draining board 200 of FIG. 5 (B) and (C) can spray rain water more uniformly onto the roof 300 from the respective water sprinkling portions 230B and 230C, thereby effectively dripping water. Unevenness of the marks can be suppressed.
図６は、本発明の実施形態に係る水切り板２００の形状に関するバリエーションを示す図であり、太陽電池モジュールアレイ１００側から水切り板２００を見た正面図を表している。但し、斜線部は図２中に示したＡＡ線の位置における断面を表す。図６（Ａ）の水切り板２００Ａは、図１に示されるように太陽電池モジュール１２０が横に３つ並んだ幅に対応した長手方向の長さを有する。図６（Ｂ）、（Ｃ）、（Ｄ）の各水切り板２００Ｂ、２００Ｃ、２００Ｄは、水切り板２００Ａのほぼ半分の長手方向の長さを有し、それぞれ太陽電池モジュールアレイ１００の軒側に２つ横に並べて設置される。図６（Ａ）、（Ｂ）において、水切り板２００Ａ及び２００Ｂの窪み２６０の底面２６０ａは、長手方向の全体にわたって平坦な面である。図６（Ｃ）の水切り板２００Ｃでは、窪み２６０の底面２６０ａが、水受け部２１０から散水部２３０へ向かって傾斜した形状に構成されている。そのため、太陽電池モジュールアレイ１００の縦目地から水受け部２１０へ落下する雨水（太い点線矢印）を、円滑に散水部２３０の方向へ流すことができる。また図６（Ｄ）の水切り板２００Ｄでは、窪み２６０の底面２６０ａは平坦面であるが、水受け部２１０に山型の突起２６５が設けられている。この構成においても同様に、突起２６５の存在によって雨水を円滑に散水部２３０の方向へ流すことができる。 FIG. 6 is a view showing variations regarding the shape of the draining plate 200 according to the embodiment of the present invention, and shows a front view of the draining plate 200 viewed from the solar cell module array 100 side. However, the hatched portion represents a cross section at the position of the AA line shown in FIG. A draining plate 200A in FIG. 6A has a length in the longitudinal direction corresponding to the width in which three solar cell modules 120 are arranged side by side as shown in FIG. Each of the draining plates 200B, 200C, and 200D in FIGS. 6B, 6C, and 6D has a length in the longitudinal direction that is almost half of the draining plate 200A, and is respectively on the eaves side of the solar cell module array 100. Two are installed side by side. 6 (A) and 6 (B), the bottom surface 260a of the recess 260 of the draining plates 200A and 200B is a flat surface over the entire longitudinal direction. In the draining plate 200 </ b> C of FIG. 6C, the bottom surface 260 a of the recess 260 is configured to be inclined from the water receiving portion 210 toward the sprinkling portion 230. Therefore, rain water (thick dotted arrow) that falls from the vertical joint of the solar cell module array 100 to the water receiving portion 210 can be smoothly flowed toward the water sprinkling portion 230. In the draining plate 200D of FIG. 6D, the bottom surface 260a of the recess 260 is a flat surface, but the water receiving portion 210 is provided with a mountain-shaped protrusion 265. Similarly, in this configuration, rainwater can be smoothly flowed in the direction of the water sprinkling unit 230 due to the presence of the protrusions 265.
以上、本発明の実施形態を説明したが、本発明はこれに限定されず、その要旨を逸脱しない範囲内において様々な変更が可能である。 As mentioned above, although embodiment of this invention was described, this invention is not limited to this, A various change is possible within the range which does not deviate from the summary.
例えば、上述した実施形態の水切り板２００のように、水受け部には貫通孔が無い方が好ましいが、水受け部に貫通孔が設けられていても構わない。そのような構成であっても、水受け部に当たった雨水は散水部へ導かれ、散水部の貫通孔から流下するため、水切り板が無い場合に比べて水垂れ痕のムラを抑制することができる。 For example, like the draining plate 200 of the above-described embodiment, it is preferable that the water receiving portion has no through hole, but the water receiving portion may be provided with a through hole. Even in such a configuration, rainwater that hits the water receiving portion is guided to the sprinkling portion and flows down from the through hole of the sprinkling portion, so that unevenness of dripping marks is suppressed as compared with the case without a draining plate. Can do.
