Description
本発明は、金属製の屋根材の錆及び腐食を抑制する太陽電池システムに関する。 The present invention relates to a solar cell system that suppresses rust and corrosion of metal roofing materials.
近年では軽量である点、施工容易である点及び低コストである点からめっき及び塗装といった表面処理が施された金属製の屋根材が傾斜屋根に使用されることが増えている。 In recent years, a metal roofing material that has been subjected to a surface treatment such as plating and painting is increasingly used for a sloping roof because of its light weight, easy construction, and low cost.
従来、傾斜屋根に太陽電池モジュールを設置する太陽電池モジュール設置架台は、屋根に取り付けるための屋根取付金具、縦桟、モジュールを固定するための固定金具及びボルトを介して太陽電池モジュールを固定する場合が多く、太陽電池モジュールと屋根との間には、屋根面から設置架台の高さ分の距離が空いていることが多い。この場合、モジュールから滴下した雨水が集中し、金属屋根の塗装などの劣化を促進することが懸念される。 Conventionally, a solar cell module installation frame for installing a solar cell module on a sloping roof is a case where the solar cell module is fixed through a roof mounting bracket for mounting on the roof, a vertical rail, a fixing bracket for fixing the module, and a bolt. In many cases, there is often a distance from the roof surface to the height of the installation stand between the solar cell module and the roof. In this case, it is feared that the rainwater dropped from the module will concentrate and accelerate the deterioration such as painting of the metal roof.
特許文献１には、太陽電池モジュールのフレームに切欠構造を設け、雨水のような液体の排出性を向上させる方法が開示されている。 Patent Document 1 discloses a method of providing a notch structure in a frame of a solar cell module to improve dischargeability of liquid such as rainwater.
しかしながら、特許文献１に開示される発明では、切欠構造から排出された雨水は排出先に集中するため、金属の屋根材に耐食性を有する塗装が施されていても、長期的に流水が集中して塗装が消失し、錆が発生して腐食が促進されてしまう。 However, in the invention disclosed in Patent Document 1, the rainwater discharged from the notch structure is concentrated at the discharge destination, so that even if the metal roofing material is coated with corrosion resistance, running water is concentrated for a long period of time. Paint disappears, rust is generated and corrosion is accelerated.
本発明は、上記に鑑みてなされたものであって、金属製の屋根材の錆及び腐食を抑制できる太陽電池システムを得ることを目的とする。 The present invention has been made in view of the above, and an object of the present invention is to obtain a solar cell system capable of suppressing rust and corrosion of a roof material made of metal.
上述した課題を解決し、目的を達成するために、本発明は、フレームの受光面側に切り欠きを有する太陽電池モジュールと、金属屋根に固定され、太陽電池モジュールが載置される太陽電池モジュール用架台とを備える。本発明は、切り欠きの下方の金属屋根を覆うカバー部材を備える。 In order to solve the above-mentioned problems and achieve the object, the present invention provides a solar cell module having a cutout on the light-receiving surface side of a frame, and a solar cell module fixed to a metal roof and mounted with the solar cell module. And a mounting base. The present invention includes a cover member that covers the metal roof below the cutout.
本発明によれば、金属製の屋根材の錆及び腐食を抑制できる太陽電池システムを得られるという効果を奏する。 According to the present invention, it is possible to obtain a solar cell system capable of suppressing rust and corrosion of a roof material made of metal.
以下に、本発明の実施の形態に係る太陽電池システムを図面に基づいて詳細に説明する。なお、この実施の形態によりこの発明が限定されるものではない。 Below, the solar cell system which concerns on embodiment of this invention is demonstrated in detail based on drawing. The present invention is not limited to this embodiment.

Embodiment 1.
FIG. 1 is an exploded perspective view of a solar cell system according to Embodiment 1 of the present invention. FIG. 2 is a partial perspective view of the solar cell module used in the solar cell system according to the first embodiment. The solar cell system 20 according to the first embodiment includes a solar cell module 1, a solar cell module mount 19 on which the solar cell module 1 is mounted, and an eaves side of the solar cell module 1 installed at an end on the eaves side. The eaves side cover 23 for protection and the ridge side cover 24 for protecting the ridge side of the solar cell module 1 installed at the ridge side end are provided.
太陽電池モジュール１は、太陽電池パネル２１と、太陽電池パネル２１の周囲を保持するフレーム２とを備えている。フレーム２は、端部付近に切り欠き３を有する。切り欠き３は、太陽電池パネル２１の四隅に当たる部分に位置している。 The solar cell module 1 includes a solar cell panel 21 and a frame 2 that holds the periphery of the solar cell panel 21. The frame 2 has a notch 3 near the end. The notches 3 are located at the portions corresponding to the four corners of the solar cell panel 21.
太陽電池モジュール用架台１９は、屋根材に取り付ける屋根取付金具４、屋根取付金具４同士を屋根傾斜方向に繋ぐ縦桟５及び太陽電池モジュール１を固定する固定金具６を備えている。 The solar cell module mount 19 includes a roof mounting bracket 4 attached to a roof material, a vertical rail 5 that connects the roof mounting brackets 4 to each other in a roof inclination direction, and a fixing bracket 6 that fixes the solar cell module 1.
屋根取付金具４は、側面視ハット型の部材であり、木ねじ７で屋根面に固定される。縦桟５は、上面に長手方向に沿ったスリットを備えた中空角棒状の部材であり、屋根取付金具４に縦桟用ボルト８とナット９とで締結される。固定金具６は、固定金具用ボルト１０とファスナー１１とで縦桟５に締結される。ファスナー１１は、縦桟５の内部に挿入される矩形状の部材であり、固定金具用ボルト１０のねじ山と適合する雌ねじが形成されている。太陽電池モジュール１は、固定金具６がフレーム２を保持することにより設置される。太陽電池モジュール用架台１９を構成する各部材は、金属製であり、適用可能な金属には、アルミニウム及び溶融亜鉛めっき鋼板を例示できるが、これらに限定されない。 The roof mounting member 4 is a side view hat type member, and is fixed to the roof surface with wood screws 7. The vertical rail 5 is a hollow rectangular rod-shaped member having slits along the longitudinal direction on the upper surface thereof, and is fastened to the roof mounting member 4 with vertical rail bolts 8 and nuts 9. The fixing bracket 6 is fastened to the vertical rail 5 with a fixing bracket bolt 10 and a fastener 11. The fastener 11 is a rectangular member that is inserted into the vertical rail 5, and has a female screw that matches the thread of the fixing bracket bolt 10. The solar cell module 1 is installed by the fixing bracket 6 holding the frame 2. Each member that constitutes the solar cell module mount 19 is made of metal, and applicable metals include aluminum and hot-dip galvanized steel sheet, but are not limited thereto.
太陽電池パネル２１の上に降った雨水は、フレーム２の切り欠き３から太陽電池モジュール１の外に排水される。切り欠き３は、フレーム２の両端部付近に設けられており、太陽電池モジュール１の四隅に当たる部分に位置しているため、太陽電池モジュール１が傾斜を持って設置されても排水できる。 Rainwater that has fallen on the solar cell panel 21 is drained to the outside of the solar cell module 1 through the notch 3 of the frame 2. Since the cutouts 3 are provided near both ends of the frame 2 and are located at the portions corresponding to the four corners of the solar cell module 1, the solar cell module 1 can be drained even if the solar cell module 1 is installed with an inclination.
太陽電池モジュール用架台１９の縦桟５は、太陽電池モジュール１の下に２本設置される。２本の縦桟５は、横方向において太陽電池モジュール１を、左側の縦桟５よりも左に位置する部分と、２本の縦桟５の間の位置する部分と、右側の縦桟５よりも右に位置する部分との比が１：１：１から１：４：１の間となるように配置されている。 Two vertical rails 5 of the solar cell module mount 19 are installed below the solar cell module 1. The two vertical rails 5 are arranged such that the solar cell module 1 is located on the left side of the left vertical rail 5 in the horizontal direction, between the two vertical rails 5, and on the right vertical rail 5. It is arranged so that the ratio to the portion located to the right of is between 1: 1: 1 and 1: 4: 1.
図３は、実施の形態１に係る太陽電池システムの斜視図である。図４は、実施の形態１に係る太陽電池システムの軒側から見た側面図である。図５は、実施の形態１に係る太陽電池システムに用いられるカバー部材の斜視図である。カバー部材１２は、縦桟５の外側の位置であって、太陽電池モジュール１の切り欠き３の下方に配置されている。カバー部材１２は、金属屋根１３に貼り付けられている。金属屋根１３は、耐候性の被覆が施された金属製である。以下の説明では、金属屋根１３は塗装めっき鋼板製であるとするが、これに限定されない。カバー部材１２は、桁方向には切り欠き３の幅以上の長さを有する。カバー部材１２は、傾斜の付いた屋根の設けられた太陽電池モジュール１の軒側に排出される雨水が金属屋根１３に直接滴下されることを防ぐ。 FIG. 3 is a perspective view of the solar cell system according to the first embodiment. FIG. 4 is a side view of the solar cell system according to Embodiment 1 viewed from the eaves side. FIG. 5 is a perspective view of a cover member used in the solar cell system according to the first embodiment. The cover member 12 is located outside the vertical rail 5 and below the cutout 3 of the solar cell module 1. The cover member 12 is attached to the metal roof 13. The metal roof 13 is made of metal with a weatherproof coating. In the following description, the metal roof 13 is made of a paint-plated steel plate, but is not limited to this. The cover member 12 has a length equal to or larger than the width of the cutout 3 in the girder direction. The cover member 12 prevents rainwater discharged to the eaves side of the solar cell module 1 provided with a sloping roof from directly dripping on the metal roof 13.
図４に示すように、カバー部材１２の横幅寸法Ｗ１は、切り欠き３の幅寸法Ｗ２よりも大きく、縦桟５から太陽電池モジュール１の端部までの寸法Ｌよりも小さい。カバー部材１２の傾斜方向の幅である縦幅は、カバー部材１２の横幅と同等である。カバー部材１２は、切り欠き３の下方に中心が位置するように金属屋根１３上に設置される。 As shown in FIG. 4, the lateral width dimension W 1 of the cover member 12 is larger than the width dimension W 2 of the notch 3 and smaller than the dimension L from the vertical crosspiece 5 to the end portion of the solar cell module 1. The vertical width, which is the width of the cover member 12 in the inclination direction, is equal to the horizontal width of the cover member 12. The cover member 12 is installed on the metal roof 13 so that its center is located below the notch 3.
カバー部材１２は、少なくとも金属屋根１３と当接する側の面が粘着性を有している。カバー部材１２は、ブチルゴムシート又はアルミニウムテープを適用可能であるが、これらに限定はされない。カバー部材１２は、粘着性を有する面を金属屋根１３に貼り付けることで固定される。これにより、カバー部材１２の設置作業が容易であり、設置後に貼り直すことによる位置調整も可能となる。 At least the surface of the cover member 12 that is in contact with the metal roof 13 is adhesive. A butyl rubber sheet or an aluminum tape can be applied to the cover member 12, but the cover member 12 is not limited thereto. The cover member 12 is fixed by sticking an adhesive surface to the metal roof 13. As a result, the installation work of the cover member 12 is easy, and the position can be adjusted by reattaching it after the installation.
雨水は、金属屋根１３からの高さＨ１が、屋根取付金具４及び縦桟５を合わせた高さＨ２以上である太陽電池モジュール１の切り欠き３から滴下されるが、カバー部材１２に弾かれて分散された後に屋根傾斜方向に流れるため、金属屋根１３に局所的に雨水が滴下されることはない。 Rainwater is dropped from the notch 3 of the solar cell module 1 whose height H 1 from the metal roof 13 is equal to or higher than the height H 2 including the roof mounting bracket 4 and the vertical rails 5, but to the cover member 12. Since it flows in the roof inclination direction after being bounced and dispersed, rainwater is not locally dropped on the metal roof 13.
金属屋根１３に局所的に雨水が滴下されることがなくなることにより、金属屋根１３の塗装及びめっきの早期劣化を抑制し、金属屋根１３の母材である鋼板に錆及び腐食が発生することを防止できる。 By preventing rainwater from dripping locally on the metal roof 13, it is possible to suppress early deterioration of coating and plating of the metal roof 13, and to prevent rust and corrosion from occurring in the steel plate that is the base material of the metal roof 13. It can be prevented.
実施の形態２．
図６は、本発明の実施の形態２に係る太陽電池システムに用いられるカバー部材の斜視図である。図７は、実施の形態２に係る太陽電池システムに用いられるカバー部材の正面図である。図８は、実施の形態２に係る太陽電池システムに用いられるカバー部材の設置状態を示す斜視図である。図９は、実施の形態２に係る太陽電池システムに用いられるカバー部材の設置状態を示す正面図である。カバー部材１２は、アルミニウム又は樹脂を材料に成型されている。カバー部材１２の表面には、溝１４が形成されている。図６及び図７に示すように、溝１４は、断面形状が三角形であり、カバー部材１２の表面は鋸歯状となっている。溝１４は、屋根傾斜方向に沿っている。
Embodiment 2.
FIG. 6 is a perspective view of a cover member used in the solar cell system according to Embodiment 2 of the present invention. FIG. 7 is a front view of a cover member used in the solar cell system according to the second embodiment. FIG. 8 is a perspective view showing an installed state of a cover member used in the solar cell system according to the second embodiment. FIG. 9 is a front view showing an installed state of a cover member used in the solar cell system according to the second embodiment. The cover member 12 is made of aluminum or resin. A groove 14 is formed on the surface of the cover member 12. As shown in FIGS. 6 and 7, the groove 14 has a triangular cross-sectional shape, and the surface of the cover member 12 is serrated. The groove 14 extends along the roof inclination direction.
カバー部材１２は、カバー部材用木ねじ１５の固定部２２が棟側に設けられており、固定部２２には溝１４が設けられていない。 The cover member 12 is provided with the fixing portion 22 of the cover member wood screw 15 on the ridge side, and the fixing portion 22 is not provided with the groove 14.
実施の形態１と同様に、カバー部材１２は、太陽電池モジュール１の切り欠き３の下方に配置され、溝１４が屋根傾斜に沿う向きで金属屋根１３にカバー部材用木ねじ１５で固定される。カバー部材１２がカバー部材用木ねじ１５で固定されることにより、カバー部材１２の長期的な固定が可能となる。なお、カバー部材用木ねじ１５の位置を雨水が集中する太陽電池モジュール１の切り欠き３の下方よりも棟側とすること、換言すると、カバー部材１２を切り欠き３よりも棟側でカバー部材用木ねじ１５により金属屋根１３に固定することで、雨漏りが発生する可能性を低減できる。 Similar to the first embodiment, the cover member 12 is arranged below the notch 3 of the solar cell module 1, and the groove 14 is fixed to the metal roof 13 with the cover member wood screw 15 in the direction along the roof inclination. By fixing the cover member 12 with the cover member wood screw 15, the cover member 12 can be fixed for a long period of time. In addition, the position of the wood screw 15 for the cover member is set to be on the ridge side below the cutout 3 of the solar cell module 1 where the rainwater is concentrated, in other words, the cover member 12 is for the cover member on the ridge side from the cutout 3. Fixing to the metal roof 13 with the wood screw 15 can reduce the possibility of rain leakage.
カバー部材１２の周辺にコーキング材を配置することで、屋根面から流れてくる雨水がカバー部材用木ねじ１５を伝って小屋裏に侵入することを防止できる。コーキング材にはシリコン系又はゴムアスファルト系のものを適用可能であるが、これらに限定されない。 By arranging the caulking material around the cover member 12, it is possible to prevent rainwater flowing from the roof surface from entering the roof of the shed through the wood screws 15 for the cover member. The caulking material may be a silicone-based or rubber asphalt-based material, but is not limited thereto.
図４に示したように、雨水は、金属屋根１３からの高さがＨ１である太陽電池モジュール１の切り欠き３から滴下される。切り欠き３から落下した雨水は、カバー部材１２まで落下するまでの間に風の影響を受けて前後移動するため、カバー部材１２上の雨水が衝突する箇所は一点に定まらず、面積を持った領域となる。切り欠き３から落下した雨水がカバー部材１２に衝突するまでの移動距離は、切り欠き３の金属屋根１３からの高さＨ１が高いほど長くなるため、屋根取付金具４及び縦桟５を合わせた高さＨ２が高いほど、雨水は分散されやすい。逆に言えば、屋根取付金具４及び縦桟５を合わせた高さＨ２が低いと、カバー部材１２上の雨水が衝突する領域が小さくなり、金属屋根１３の一部分に集中して雨水が流れやすくなる。 As shown in FIG. 4, rainwater is dripped from the notch 3 of the solar cell module 1 whose height from the metal roof 13 is H 1 . The rainwater that has fallen from the notch 3 moves back and forth under the influence of wind until it falls to the cover member 12, so the location on the cover member 12 where the rainwater collides is not fixed and has an area. It becomes an area. The higher the height H 1 of the cutout 3 from the metal roof 13 is, the longer the travel distance until the rainwater that falls from the cutout 3 collides with the cover member 12. The higher the height H 2 is, the more easily rainwater is dispersed. Conversely speaking, if the height H 2 of the roof mounting bracket 4 and the vertical rails 5 combined is low, the area where the rainwater collides with the cover member 12 becomes small, and the rainwater concentrates on a part of the metal roof 13 and flows. It will be easier.
実施の形態２に係るカバー部材１２に設けられた溝１４は、太陽電池モジュール１の金属屋根１３からの屋根取付金具４及び縦桟５を合わせた高さＨ２が低く、太陽電池モジュール１の切り欠き３から滴下される雨水がカバー部材１２に滴下され、雨水が分散されにくい場合においても、のこぎり形状により雨水を分散させる効果がある。これにより、カバー部材１２から金属屋根１３に流れた雨水が一部分に集中せず、流水に対しても塗装及びめっきの寿命を延ばすことが可能となる。 The groove 14 provided in the cover member 12 according to the second embodiment has a low height H 2 of the roof mounting bracket 4 and the vertical rail 5 from the metal roof 13 of the solar cell module 1, Even when the rainwater dropped from the notch 3 is dropped on the cover member 12 and the rainwater is difficult to be dispersed, the rainwater is dispersed by the saw shape. As a result, the rainwater that has flowed from the cover member 12 to the metal roof 13 is not concentrated on a part, and the life of painting and plating can be extended even with running water.
実施の形態３．
図１０は、本発明の実施の形態３に係る太陽電池システムに用いられるカバー部材の斜視図である。実施の形態３に係るカバー部材１２の上面には、ピラミッド型の突起１８が複数形成されている。複数の突起１８は、屋根の傾斜に沿った方向に対角の頂点１８ａ，１８ｂが位置するように配列されている。したがって、突起１８同士を隔てる溝１４は、屋根の傾斜に対して斜め方向に形成されている。
Embodiment 3.
FIG. 10 is a perspective view of a cover member used in the solar cell system according to Embodiment 3 of the present invention. A plurality of pyramid-shaped protrusions 18 are formed on the upper surface of the cover member 12 according to the third embodiment. The plurality of protrusions 18 are arranged such that diagonal apexes 18a and 18b are located in a direction along the slope of the roof. Therefore, the groove 14 that separates the protrusions 18 from each other is formed obliquely with respect to the inclination of the roof.
実施の形態３においては、カバー部材１２の表面に沿って流れる雨水は、突起１８の棟側の頂点１８ａにおいて左右に分散される。したがって、カバー部材１２を流れ下るに従い、雨水は左右方向に分散される。これにより、カバー部材１２から金属屋根１３に流れた雨水が一部分に集中せず、流水に対しても塗装及びめっきの寿命を延ばすことが可能となる。 In the third embodiment, the rainwater flowing along the surface of the cover member 12 is dispersed right and left at the apex 18a of the protrusion 18 on the ridge side. Therefore, as the water flows down the cover member 12, the rainwater is dispersed in the left-right direction. As a result, the rainwater that has flowed from the cover member 12 to the metal roof 13 is not concentrated on a part, and the life of painting and plating can be extended even with running water.
実施の形態４．
図１１は、本発明の実施の形態４に係る太陽電池システムに用いられるカバー部材の斜視図である。図１２は、実施の形態４に係る太陽電池システムに用いられるカバー部材の正面図である。カバー部材１２は、２層構造となっており、カバー部材第１層１６は、粘着性を持たない材料で形成されており、表面には溝１４が形成されている。カバー部材第１層１６の材料には、アルミニウム又は樹脂を適用できるがこれに限定されない。溝１４は、断面形状が三角形であり、カバー部材１２の表面は鋸歯状となっている。溝１４は、屋根傾斜方向に沿っている。カバー部材第２層１７は、両面に粘着性を有する材料が用いられている。粘着性を有する材料にはブチルゴムを適用可能であるが、これに限定されない。カバー部材第２層１７の一方の面は、金属屋根１３との接触面となっている。

FIG. 12 is a front view of a cover member used in the solar cell system according to the fourth embodiment. The cover member 12 has a two-layer structure, the cover member first layer 16 is formed of a material having no adhesive property, and the groove 14 is formed on the surface thereof. Aluminum or resin can be applied to the material of the cover member first layer 16, but the material is not limited to this. The groove 14 has a triangular cross-sectional shape, and the surface of the cover member 12 is serrated. The groove 14 extends along the roof inclination direction. The cover member second layer 17 is made of a material having adhesiveness on both sides. Butyl rubber can be applied to the material having adhesiveness, but is not limited thereto. One surface of the cover member second layer 17 is a contact surface with the metal roof 13.
カバー部材第１層１６は、カバー部材第２層１７の周縁部から全周にわたって張り出した状態でカバー部材第２層１７の他方の面に粘着されている。すなわち、カバー部材第１層１６は縦方向及び横方向ともに、カバー部材第２層１７以上の寸法を有している。 The cover member first layer 16 is adhered to the other surface of the cover member second layer 17 in a state of protruding from the peripheral edge of the cover member second layer 17 over the entire circumference. That is, the cover member first layer 16 has a dimension equal to or larger than the cover member second layer 17 in both the vertical direction and the horizontal direction.
カバー部材１２は、太陽電池モジュール１の切り欠き３の下方に配置され、カバー部材第２層１７の粘着性によって金属屋根１３に固定される。 The cover member 12 is arranged below the notch 3 of the solar cell module 1, and is fixed to the metal roof 13 by the adhesiveness of the cover member second layer 17.
カバー部材第１層１６は、カバー部材第２層１７を覆うため、太陽電池システムの外周部にカバー部材１２を取り付ける場合でも、直射日光によりカバー部材第２層１７が劣化して粘着性が損なわれることを防止できる。 Since the cover member first layer 16 covers the cover member second layer 17, even when the cover member 12 is attached to the outer peripheral portion of the solar cell system, the cover member second layer 17 is deteriorated by direct sunlight and the adhesiveness is impaired. Can be prevented.
カバー部材第１層１６の表面に溝１４を設けることにより効果は、実施の形態２と同様であるため、説明は省略する。なお、カバー部材第１層１６の表面には、実施の形態３と同様のピラミッド形状の突起を設けてもよい。 The effect obtained by providing the groove 14 on the surface of the cover member first layer 16 is the same as that of the second embodiment, and therefore the description thereof is omitted. The surface of the cover member first layer 16 may be provided with the same pyramid-shaped protrusion as in the third embodiment.
実施の形態４に係るカバー部材１２は、金属屋根１３に固定する際にねじ止め作業が不要であるため、実施の形態２に係るカバー部材と比較すると設置作業の労力を軽減できる。 Since the cover member 12 according to the fourth embodiment does not require screwing work when fixing the cover member 12 to the metal roof 13, the labor of installation work can be reduced as compared with the cover member according to the second embodiment.
以上の実施の形態に示した構成は、本発明の内容の一例を示すものであり、別の公知の技術と組み合わせることも可能であるし、本発明の要旨を逸脱しない範囲で、構成の一部を省略、変更することも可能である。 The configurations shown in the above embodiments show an example of the content of the present invention, and can be combined with other known techniques, and the configurations of the configurations are possible without departing from the gist of the present invention.
