JP 2003-262017 A Japanese Patent Laid-Open No. 2003-293531

しかしながら、従来は、カバー部材の下辺部に雪止め部を設けていたため、降雪時には太陽電池パネルを効果的に利用することができなかった。   However, conventionally, since the snow stopper is provided on the lower side of the cover member, the solar cell panel cannot be used effectively during snowfall.

また、上述した防水構造においては、シーリング材のみにより防水していたため、シーリング材が傷ついたり切れたりした場合には、カバー部材の端縁と太陽電池パネルの周縁部上面との間から漏水する虞があった。   Further, since the waterproof structure described above is waterproofed only by the sealing material, there is a possibility that water leaks from between the edge of the cover member and the upper surface of the peripheral portion of the solar cell panel when the sealing material is damaged or cut. was there.

そこで、この発明は、降雪時にも太陽電池パネルを効果的に利用することができると共に、シーリング材の損傷があっても、カバー部材と太陽電池パネルの縁部との間からの漏水を確実に防止できる太陽発電システムの防水構造を提供することを目的とするものである。   Therefore, the present invention can effectively use the solar cell panel even during snowfall, and reliably leaks water between the cover member and the edge of the solar cell panel even if the sealing material is damaged. An object of the present invention is to provide a waterproof structure for a solar power generation system that can be prevented.

この目的を達成するため、請求項１の発明は、傾斜屋根上に太陽電池パネルが取り付けられ、前記太陽電池パネルのパネル縁部を覆うカバー部材が設けられていると共に、前記カバー部材の前記パネル縁部上面に臨む端縁と前記パネル縁部上面との間に防水用のシーリング材が施された太陽発電システムの防水構造であって、前記太陽電池パネルの上面は雪が滑り落ちることが可能な所定値以上の傾斜角度の平滑面に形成され、前記カバー部材と前記パネル縁部上面との間に防水用の水密材が介装されている太陽発電システムの防水構造としたことを特徴とする。   In order to achieve this object, according to the invention of claim 1, a solar cell panel is mounted on an inclined roof, a cover member that covers a panel edge of the solar cell panel is provided, and the panel of the cover member is provided. A waterproof structure of a solar power generation system in which a sealing material for waterproofing is applied between an edge that faces the upper surface of the edge and the upper surface of the panel edge, and the upper surface of the solar cell panel is predetermined to allow snow to slide down A waterproof structure for a solar power generation system is provided, which is formed on a smooth surface having an inclination angle equal to or greater than a value, and a waterproof watertight material is interposed between the cover member and the upper surface of the panel edge.

また、請求項２の発明は、請求項１に記載の太陽発電システムの防水構造において、 請求項１に記載の太陽発電システムの防水構造において、前記傾斜屋根の太陽電池パネルより下方の水下部分が前記太陽電池パネル上を滑り落ちた雪が積雪しない程度に短く形成されていることを特徴とする。   Further, the invention of claim 2 is the waterproof structure of the solar power generation system according to claim 1, in the waterproof structure of the solar power generation system according to claim 1, wherein the underwater portion below the solar battery panel of the inclined roof. Is formed so as to be short enough that snow that has slipped down on the solar panel does not accumulate.

更に、請求項３の発明は、請求項１又は請求項２に記載の太陽発電システムの防水構造において、前記シーリング材は前記太陽電池パネルの上面から滑り落ちる雪の移動を阻止しないように上面が前記パネル縁部上面から前記カバー部材の上面まで傾斜させられていることを特徴とする。   Furthermore, the invention of claim 3 is the waterproof structure of the solar power generation system according to claim 1 or claim 2, wherein the sealing material does not prevent movement of snow falling from the upper surface of the solar cell panel. It is inclined from the upper surface of the panel edge to the upper surface of the cover member.

請求項１の発明によれば、太陽電池パネル上への降雪時に雪が滑り落ちて、太陽電池パネル上に積雪しないので、降雪時にも太陽電池パネルを効果的に利用することができる。しかも、シーリング材の損傷があっても、カバー部材と太陽電池パネルの縁部との間からの漏水を確実に防止できる。   According to the first aspect of the present invention, snow slides down when snowing on the solar cell panel and does not accumulate on the solar cell panel, so that the solar cell panel can be effectively used even during snowfall. Moreover, even if the sealing material is damaged, it is possible to reliably prevent water leakage from between the cover member and the edge of the solar cell panel.

また、請求項２の発明によれば、 前記傾斜屋根の太陽電池パネルより下方の水下部分の傾斜方向の長さが前記太陽電池パネル上を滑り落ちた雪が積雪しない程度に短く形成されているので、降雪時に太陽電池パネルから滑り落ちる雪が水下部分に溜まることがない。この結果、太陽電池パネル上に積雪するのを確実に防止して、降雪時にも太陽電池パネルを効果的に利用することができる。   Moreover, according to invention of Claim 2, the length of the inclination direction of the submerged part below the solar cell panel of the said inclination roof is formed short so that the snow which slid down on the said solar cell panel may not accumulate snow. Therefore, snow that slides down from the solar cell panel during snowfall does not accumulate in the underwater part. As a result, it is possible to reliably prevent snow on the solar cell panel and to effectively use the solar cell panel even during snowfall.

更に、請求項３の発明によれば、前記太陽電池パネルの上面から滑り落ちる雪がシーリング材の傾斜する上面に案内されてカバー部材の上面に滑らかに案内されるので、前記カバー部材は前記太陽電池パネルの上面から滑り落ちる雪の移動を阻止するようなことは生じない。   Furthermore, according to the invention of claim 3, the snow sliding down from the upper surface of the solar cell panel is guided to the upper surface of the sealing material which is inclined and smoothly guided to the upper surface of the cover member. There is no such thing as preventing the snow from sliding down from the top surface.

Note that the slope is not limited to 5.5 inches as long as the slope is such that the snow slides down during snowfall.

また、カバー部材１６は、上支持板部１２ｄ及びパネル縁部上面１５ｂ上に跨る上カバー板部１６ａと、この上カバー板部１６ａの屋根傾斜方向下端から下方に垂直に折曲されたカバー部１６ｂを備えている。この上カバー板部１６ａの傾斜方向の巾は例えば３７ｍｍと短くして、雪庇ができないようになっている。また、カバー部１６ｂの上下方向巾（上下方向高さ）も例えば３７ｍｍに形成されている。   The cover member 16 includes an upper cover plate portion 16a straddling the upper support plate portion 12d and the panel edge upper surface 15b, and a cover portion bent vertically downward from the lower end in the roof inclination direction of the upper cover plate portion 16a. 16b. The width of the upper cover plate portion 16a in the inclination direction is shortened to 37 mm, for example, so that snow cannot be formed. Further, the vertical width (vertical height) of the cover portion 16b is also set to 37 mm, for example.

この上カバー板部１６ａは、図２，図３に示したように上支持板部１２ｄに当接する板部１６ａ１と、この板部１６ａ１の屋根傾斜方向上端からパネル縁部上面１５ｂ上に向けて傾斜する傾斜板部１６ａ２と、傾斜板部１６ａ２の下側に折り返された折り返し板部１６ａ３を有する。そして、板部１６ａ１には図２，図４に示したように挿通孔１４と一致する挿通孔１７が形成され、図２，図３，図５に示したように折り返し板部１６ａ３の下面には弾性部材製の水密材１８が固着されている。この水密材１８は、圧縮前の状態では図３に示したように断面が方形状に形成されている。   As shown in FIGS. 2 and 3, the upper cover plate portion 16a includes a plate portion 16a1 that comes into contact with the upper support plate portion 12d, and an upper end of the plate portion 16a1 in the roof inclination direction toward the panel edge upper surface 15b. It has the inclined board part 16a2 which inclines, and the folding | turning board part 16a3 folded by the downward side of the inclined board part 16a2. The plate portion 16a1 is formed with an insertion hole 17 that coincides with the insertion hole 14 as shown in FIGS. 2 and 4, and is formed on the lower surface of the folded plate portion 16a3 as shown in FIGS. The watertight material 18 made of an elastic member is fixed. As shown in FIG. 3, the watertight material 18 has a square cross section before being compressed.

また、図２，図５に示したように挿通孔１７，１４，１１にはボルト１９が上側から挿通され、このボルト１９の下端部には袋ナット２０が螺着されている。これにより、カバー部材１６の上カバー板部１６ａは、パネル支持枠１２の上支持板部１２ｄと共に屋根仕上材１０の上支持板部１０ｅに固定されている。   As shown in FIGS. 2 and 5, a bolt 19 is inserted into the insertion holes 17, 14, and 11 from above, and a cap nut 20 is screwed to the lower end portion of the bolt 19. Thus, the upper cover plate portion 16a of the cover member 16 is fixed to the upper support plate portion 10e of the roofing material 10 together with the upper support plate portion 12d of the panel support frame 12.

そして、この固定により水密材１８は、図３の断面が方形状態から圧縮変形させられてパネル縁部上面１５ｂに弾接し、折り返し板部１６ａ３とパネル縁部上面１５ｂとの間から保持溝１３側に水が漏れないように水密にシールしている。   Then, by this fixing, the watertight member 18 is compressed and deformed from the rectangular state in FIG. 3 to elastically contact the panel edge upper surface 15b, and between the folded plate portion 16a3 and the panel edge upper surface 15b, the holding groove 13 side. It is sealed tightly so that water does not leak.

さらに、傾斜板部１６ａ２と折り返し板部１６ａ３との折返部（折曲部）１６ａ４とパネル縁部上面１５ｂとの間には、シーリング材２１が施されている。このシーリング材２１の上面２１ａは、太陽電池パネル１５の上面から傾斜板部１６ａ２に雨水や雪等が滑らかに流下できるように傾斜させられている。   Further, a sealing material 21 is provided between the folded portion (folded portion) 16a4 between the inclined plate portion 16a2 and the folded plate portion 16a3 and the panel edge portion upper surface 15b. The upper surface 21a of the sealing material 21 is inclined so that rainwater, snow, etc. can flow smoothly from the upper surface of the solar cell panel 15 to the inclined plate portion 16a2.

また、屋根仕上材１０の傾斜板部１０ａの傾斜方向長さは、太陽電池パネル１５が傾斜方向及び横方向に配列された複数の太陽電池セルから構成されている場合、太陽電池パネル（太陽電池モジュール）１５の傾斜方向長さ（１２７mm）よりも短い長さ（例えば９０mm）に形成する。即ち、屋根仕上材１０の傾斜板部１０ａの傾斜方向長さは、太陽電池パネル１５から滑り落ちた雪が傾斜板部１０ａ上に積雪しない程度に短く形成する。例えば、屋根仕上材１０の傾斜板部１０ａの長さは１２０mm〜１０mmでも良い。   Moreover, the inclination direction length of the inclination board part 10a of the roofing material 10 is a solar cell panel (solar cell), when the solar cell panel 15 is comprised from the several photovoltaic cell arranged in the inclination direction and the horizontal direction. The module 15 is formed to have a length (for example, 90 mm) shorter than the length (127 mm) in the inclination direction. That is, the inclination direction length of the inclined plate portion 10a of the roofing finish 10 is formed so short that the snow that has slipped off from the solar cell panel 15 does not accumulate on the inclined plate portion 10a. For example, the length of the inclined plate portion 10a of the roof finishing material 10 may be 120 mm to 10 mm.

このように屋根仕上材１０の傾斜板部１０ａの長さを太陽電池セル（図示せず）の傾斜方向の長さより短く設定すると、屋根上への太陽電池セルの設置枚数（設置した太陽電池セルの発電のための効果的な使用枚数）が増え、発電効率の良いものとなる。   As described above, when the length of the inclined plate portion 10a of the roofing material 10 is set shorter than the length of the solar cell (not shown) in the inclination direction, the number of solar cells installed on the roof (installed solar cells) The number of effective use for power generation) is increased, and power generation efficiency is improved.

尚、太陽電池パネル１５から滑り落ちた雪が傾斜板部１０ａ上に積雪しない程度に、傾斜板部１０ａの傾斜方向の長さが設定されていれば、傾斜板部１０ａの傾斜方向の長さは上述した長さ（寸法）に限定されるものではない。   In addition, if the length of the inclined direction of the inclined plate part 10a is set to such an extent that the snow sliding from the solar cell panel 15 does not accumulate on the inclined plate part 10a, the length of the inclined plate part 10a in the inclined direction is It is not limited to the length (dimension) described above.

次に、このような構成の作用を説明する。   Next, the operation of such a configuration will be described.

このような構成によれば、太陽電池パネル上への降雪時に、雪が太陽電池パネル１５上を滑り落ちて、滑り落ちる雪はシーリング材２１の上面２１ａに案内されてカバー部材１６の上カバー板部１６ａ上に滑り落ちる。そして、この雪は、最終的には屋根仕上材１０の傾斜板部１０ａ上に落下した後、傾斜板部１０ａ上を滑り落ちる。   According to such a configuration, when snow falls on the solar cell panel, the snow slides down on the solar cell panel 15, and the snow falling down is guided to the upper surface 21 a of the sealing material 21 and the upper cover plate portion 16 a of the cover member 16. Slide down. And this snow finally falls on the inclined board part 10a of the roof finishing material 10, and then slides down on the inclined board part 10a.

この結果、降雪時に太陽電池パネル上に積雪しないので、降雪時にも太陽電池パネルを効果的に利用することができる。   As a result, since no snow is accumulated on the solar cell panel during snowfall, the solar cell panel can be effectively used even during snowfall.

しかも、太陽電池パネル１５上に降った雨や降雪時の雪がとけた水が、雨水として傾斜する太陽電池パネル１５上を流下して、上述した雪と同様にシーリング材２１を介して上カバー板部１６ａ上に流れる。この際に、通常は、雨水がシーリング材２１により水密材１８側に漏れるのを防止している。   Moreover, the rain that has fallen on the solar cell panel 15 or the water from which the snow has melted flows down on the solar cell panel 15 inclined as rainwater, and the upper cover plate via the sealing material 21 in the same manner as the snow described above. It flows on the part 16a. At this time, normally, rainwater is prevented from leaking to the watertight material 18 side by the sealing material 21.

また、何らかの原因で、シーリング材２１が損傷して、雨水が水密材１８側に漏れても、水密材１８は漏れた雨水が保持溝１３側に漏れるのを確実に防止する。
従って、カバー部材１６と太陽電池パネル１５の縁部との間からの漏水を確実に防止できる。 Moreover, even if the sealing material 21 is damaged for some reason and rainwater leaks to the watertight material 18 side, the watertight material 18 reliably prevents the leaked rainwater from leaking to the holding groove 13 side.
Therefore, water leakage between the cover member 16 and the edge of the solar cell panel 15 can be reliably prevented.

以上説明したように、この発明の実施の形態の太陽発電システムの防水構造では、傾斜屋根１上に太陽電池パネル１５が取り付けられ、前記太陽電池パネル１５のパネル縁部１５ａを覆うカバー部材１６が設けられていると共に、前記カバー部材１６の前記パネル縁部上面１５ｂに臨む端縁（折返部１６ａ４）と前記パネル縁部上面１５ｂとの間に防水用のシーリング材２１が施されている。しかも、前記太陽電池パネル１５の上面は雪が滑り落ちることが可能な所定値以上の傾斜角度の平滑面に形成され、前記カバー部材１６と前記パネル縁部上面１５との間に防水用の水密材２１が介装されている。   As described above, in the waterproof structure of the solar power generation system according to the embodiment of the present invention, the solar cell panel 15 is attached on the inclined roof 1, and the cover member 16 that covers the panel edge 15a of the solar cell panel 15 is provided. A waterproof sealant 21 is provided between the edge (folded portion 16a4) of the cover member 16 facing the panel edge upper surface 15b and the panel edge upper surface 15b. In addition, the upper surface of the solar cell panel 15 is formed as a smooth surface having an inclination angle equal to or greater than a predetermined value at which snow can slide down, and a waterproof watertight material 21 between the cover member 16 and the panel edge upper surface 15. Is intervening.

この構成によれば、太陽電池パネル１５上への降雪時に雪が滑り落ちて、太陽電池パネル１５上に積雪しないので、降雪時にも太陽電池パネル１５を効果的に利用することができる。しかも、シーリング材２１の損傷があっても、カバー部材１６と太陽電池パネル１５の縁部との間からの漏水を確実に防止できる。   According to this configuration, since snow slides down when snowing on the solar cell panel 15 and does not accumulate on the solar cell panel 15, the solar cell panel 15 can be effectively used even during snowfall. Moreover, even if the sealing material 21 is damaged, water leakage from between the cover member 16 and the edge of the solar cell panel 15 can be reliably prevented.

また、この発明の実施の形態の太陽発電システムの防水構造では、前記傾斜屋根の太陽電池パネルより下方の水下部分（傾斜板部１０ａ）の傾斜方向の長さが前記太陽電池パネル１５上を滑り落ちた雪が積雪しない程度に短く形成されている。   Moreover, in the waterproof structure of the solar power generation system according to the embodiment of the present invention, the length in the inclined direction of the submerged portion (inclined plate portion 10a) below the solar cell panel of the inclined roof is above the solar cell panel 15. It is formed short enough to prevent snow from falling.

この構成によれば、前記傾斜屋根１の太陽電池パネル１５より下方の水下部分が太陽電池パネル１５上を滑り落ちた雪が積雪しない程度に短く形成されているので、降雪時に太陽電池パネル１５から滑り落ちる雪が水下部分に溜まることがない。この結果、太陽電池パネル１５上に積雪するのを確実に防止して、降雪時にも太陽電池パネルを効果的に利用することができる。   According to this configuration, the lower portion of the sloped roof 1 below the solar cell panel 15 is formed so short that the snow that has slid down on the solar cell panel 15 does not accumulate. Snow that slides does not collect in the underwater area. As a result, it is possible to reliably prevent snow on the solar cell panel 15 and to effectively use the solar cell panel even during snowfall.

更に、この発明の実施の形態の太陽発電システムの防水構造において、前記シーリング材２１は前記太陽電池パネル１５の上面から滑り落ちる雪の移動を阻止しないように上面が前記パネル縁部上面１５ｂから前記カバー部材１６の上面まで傾斜させられている。   Furthermore, in the waterproof structure of the solar power generation system according to the embodiment of the present invention, the upper surface of the sealing material 21 from the panel edge upper surface 15b is not covered with the cover so as not to prevent the snow that slides down from the upper surface of the solar cell panel 15. It is inclined to the upper surface of the member 16.

この構成によれば、前記太陽電池パネル１５の上面から滑り落ちる雪がシーリング材２１の傾斜する上面２１ａに案内されてカバー部材の上面に滑らかに案内されるので、前記カバー部材１６は前記太陽電池パネル１５の上面から滑り落ちる雪の移動を阻止するようなことは生じない。   According to this configuration, the snow that slides down from the upper surface of the solar cell panel 15 is guided to the upper surface 21a of the sealing material 21 and is smoothly guided to the upper surface of the cover member. There is no such thing as preventing the snow from sliding down from the top surface.

以上、図面を参照して、本発明の実施例を詳述してきたが、具体的な構成は、この実施例に限らず、本発明の要旨を逸脱しない程度の設計的変更は、本発明に含まれる。   The embodiment of the present invention has been described in detail with reference to the drawings, but the specific configuration is not limited to this embodiment, and design changes that do not depart from the gist of the present invention are not limited to the present invention. included.
