The power generation element is composed of a semiconductor element mainly made of silicon, and converts solar energy into electric energy for output, and its conversion efficiency is about 20 to 30%. Since this type of power generation element is already widely known, detailed description thereof is omitted. Moreover, it does not limit about the detailed specification etc. of an electric power generation element. The panel body 11 of the present embodiment has a substantially rectangular shape when viewed from the front (that is, the surface that receives sunlight).
パネル枠材１２は、パネル本体１１の周囲を覆って保持するもので、本実施形態ではアルミニウム等の金属で形成される型材からなるが、材質はアルミニウムに限定されず、金属にも限定されない。またパネル枠材１２は、パネル本体１１の各辺に対応する部分毎に別体となっていてもよいし、パネル本体１１の隣接する辺に対応する部分が連結されて一体となっていてもよく、特に限定されない。このパネル枠材１２にパネル本体１１が保持されて、太陽光発電パネル１が構成される。

In addition, the panel frame member 12 may be separated for each portion corresponding to each side of the panel body 11, or may be integrated by connecting portions corresponding to adjacent sides of the panel body 11. Well, not particularly limited. The panel main body 11 is held by the panel frame member 12 to constitute the photovoltaic power generation panel 1.
図２および図３Ａ、３Ｂに示すように、太陽光発電パネル１は、パネル取付部材２を介して建物の屋根材３に取り付けられる。パネル取付部材２は、図３Ａに示すように、取付部材本体２１と、パネル取付用ボルト２２およびパネル取付用ナット２３と、押さえ部材２０とで構成される。取付部材本体２１は、アルミニウムや鋼等の金属で形成される部材で、屋根材３に取り付けられる部分にビスやねじや釘等からなる固着具２４が挿通される挿通孔２５が形成されるもので、本実施形態ではピース材である。取付部材本体２１に形成された挿通孔２５に固着具２４が挿通されて、取付部材本体２１が屋根材３に取り付けられる。また、取付部材本体２１の材質は、アルミニウムや鋼に限定されず、金属にも限定されない。
As shown in FIG. 2 and FIGS. 3A and 3B, the solar power generation panel 1 is attached to the roofing material 3 of the building via the panel attachment member 2. As shown in FIG. 3A, the panel mounting member 2 includes a mounting member main body 21, panel mounting bolts 22 and panel mounting nuts 23, and a pressing member 20. The attachment member main body 21 is a member formed of a metal such as aluminum or steel, and has an insertion hole 25 through which a fixing tool 24 made of a screw, a screw, a nail or the like is inserted in a portion attached to the roofing material 3. In this embodiment, it is a piece material. The fixing tool 24 is inserted into the insertion hole 25 formed in the attachment member main body 21, and the attachment member main body 21 is attached to the roof material 3. Moreover, the material of the attachment member main body 21 is not limited to aluminum or steel, and is not limited to metal.
取付部材本体２１には、パネル取付用ボルト２２が挿通されるボルト挿通孔２６が形成されている。また、隣接する太陽光発電パネル１のパネル枠材１２の互いに対向する外面に、上方に向けて突出する起立片２７が設けられる。そして、隣接する太陽光発電パネル１のパネル枠材１２の起立片２７に、断面が下向きに開口するコ字状をした押さえ部材２０が上方より被せられる。押さえ部材２０には、パネル取付用ボルト２２が挿通されるボルト挿通孔（不図示）が形成されている。そして、取付部材本体２１のボルト挿通孔２６と押さえ部材２０のボルト挿通孔とに挿通されたパネル取付用ボルト２２にパネル取付用ナット２３が螺合されて、パネル枠材１２がパネル取付部材２に取り付けられる。
The mounting member main body 21 is formed with a bolt insertion hole 26 through which the panel mounting bolt 22 is inserted. Moreover, the standing piece 27 which protrudes upwards is provided in the outer surface which the panel frame material 12 of the adjacent photovoltaic power generation panel 1 mutually opposes. Then, a pressing member 20 having a U-shape with a cross section opened downward is put on the upright piece 27 of the panel frame member 12 of the adjacent photovoltaic power generation panel 1 from above. The holding member 20 has a bolt insertion hole (not shown) through which the panel mounting bolt 22 is inserted. Then, the panel mounting nut 23 is screwed into the panel mounting bolt 22 inserted through the bolt insertion hole 26 of the mounting member main body 21 and the bolt insertion hole of the pressing member 20, so that the panel frame member 12 becomes the panel mounting member 2. Attached to.
パネル取付部材２は、屋根材３上において、その長手方向を軒棟方向に向けながら軒方向に列をなすように複数個が間隔をあけて並設され、この列が軒棟方向に沿って間隔をあけて複数列設けられる。本実施形態の屋根材３は陸屋根ではなく、軒方向に向けて下方に傾斜している。そして、太陽光発電パネル１が上記のようにパネル取付部材２に取り付けられるもので、図２においては、軒棟方向に沿って４列設けられているが、列数や各列において並設されるパネル枚数は勿論限定されない。なお、軒方向とは軒（屋根の下端部）に沿った方向のことを意味し、軒棟方向とは屋根の棟（頂部）から軒（屋根の下端部）に沿った方向、すなわち屋根面において軒方向に対して垂直方向のことを意味する。
A plurality of the panel mounting members 2 are arranged in parallel on the roof material 3 so as to form a row in the eave direction while the longitudinal direction thereof is directed to the eave building direction. A plurality of rows are provided at intervals. The roofing material 3 of this embodiment is not a flat roof, but is inclined downward toward the eaves direction. And the photovoltaic power generation panel 1 is attached to the panel attachment member 2 as described above, and in FIG. 2, four rows are provided along the eaves ridge direction. Of course, the number of panels is not limited. The eave direction means the direction along the eave (lower end of the roof), and the eave direction refers to the direction along the eave (lower end of the roof) from the roof ridge (top), that is, the roof surface. Means the direction perpendicular to the eave direction.
ところで、太陽光発電パネル１における発電は、高温下で効率が低下する。すなわち、太陽光発電パネル１の周囲の雰囲気温度が高い場合や、太陽光発電パネル１に直射日光が照射される場合、発電素子が高温になって発電効率（変換効率）が低下するものである。発電効率の低下は、太陽光発電パネル１の温度上昇幅１０Ｋに対し、４％程度である（すなわち元の変換効率２０～３０％に対し低下後の変換効率は１６～２６％程度である）。このため、太陽光発電パネル１の温度が５０℃にまで上昇すると、設計上の基準温度である２５℃時の上記発電効率に対して、１０％程度発電効率が低下することとなる。
Incidentally, the power generation in the photovoltaic power generation panel 1 decreases in efficiency at high temperatures.

In this embodiment, as shown in FIG. 5, the water supply pipe 72 is connected to the upper end portion of the water guide material 6. . Thereby, the water supplied from the water supply pipe 72 to the upper end portion of the water guide material 6 flows by its own weight toward the lower end portion of the water guide material 6. The water guide member 6 is preferably filled with water supplied from the water supply pipe 72.
以下、本発明の作用について説明する。
Hereinafter, the operation of the present invention will be described.
貯水タンク７１に貯留された水は、ポンプにより給水管７２を介して導水材６の上端部に搬送される。導水材６の上端部に水が供給されて導水材６内に水が貯まると、導水材６は透水性を有しているため、導水管５０内と透湿性保持部材４０内に流入する。導水管５０内に流入した水は、第二の吸水性部材５により保持されるとともに、第一の吸水性部材４に吸収されていく。第一の吸水性部材４に吸収された水は、太陽光発電パネル１からの熱（主に伝導熱であるが、放射熱があってもよい）により蒸発し、透湿性保持部材４０の多数の孔を介して透湿性保持部材４０の外部に放散される。これにより、第一の吸水性部材４に吸収されている水が蒸発により減少すると、第一の吸水性部材４が第二の吸水性部材５に吸収されている水を吸収して、水が補充される。
The water stored in the water storage tank 71 is conveyed to the upper end portion of the water guiding material 6 through the water supply pipe 72 by a pump. When water is supplied to the upper end portion of the water guide material 6 and the water is stored in the water guide material 6, the water guide material 6 has water permeability and flows into the water guide pipe 50 and the moisture permeable holding member 40. The water flowing into the water guide pipe 50 is held by the second water absorbing member 5 and is absorbed by the first water absorbing member 4. The water absorbed by the first water-absorbing member 4 evaporates due to heat from the photovoltaic power generation panel 1 (mainly conduction heat, but may have radiant heat), and a large number of moisture-permeable holding members 40 are obtained. Is diffused to the outside of the moisture-permeable holding member 40 through the holes. Thereby, when the water absorbed by the first water absorbent member 4 is reduced by evaporation, the first water absorbent member 4 absorbs the water absorbed by the second water absorbent member 5 and the water is absorbed. To be replenished.
また、第一の吸水性部材４と第二の吸水性部材５と導水材６の通水率（単位面積当りの単位時間当り流量）は、内部が空洞である導水材６が最も高く、次に第二の吸水性部材５が高く、第一の吸水性部材４が最も低い。これにより、第二の吸水性部材５と導水材６とが用いられず第一の吸水性部材４のみが用いられる場合に比べて、速く全体に水が行き渡る。
The water permeability of the first water absorbent member 4, the second water absorbent member 5, and the water guide material 6 (flow rate per unit time per unit area) is highest in the water guide material 6 having a hollow inside, The second water absorbing member 5 is high and the first water absorbing member 4 is the lowest. Thereby, compared with the case where the 2nd water absorbing member 5 and the water conveyance material 6 are not used, but only the 1st water absorbing member 4 is used, water spreads to the whole faster.
なお、第一の吸水性部材４と第二の吸水性部材５の通水率は、細孔または細溝の径や大きさや全体に占める割合、合成樹脂の材質により、適宜設定可能である。また、第一の吸水性部材４と第二の吸水性部材５の種類は、合成樹脂に限定されない。
The water permeability of the first water-absorbing member 4 and the second water-absorbing member 5 can be appropriately set depending on the diameter and size of the pores or fine grooves, the ratio of the whole to the entire groove, and the material of the synthetic resin. Moreover, the kind of the 1st water absorbing member 4 and the 2nd water absorbing member 5 is not limited to a synthetic resin.
上記のように、第一の吸水性部材４に吸収されている水が蒸発する際、気化熱として太陽光発電パネル１から熱を奪い、太陽光発電パネル１が冷却され、太陽光発電パネル１における発電効率の低下を抑えることができる。
As described above, when the water absorbed by the first water absorbing member 4 evaporates, heat is removed from the photovoltaic power generation panel 1 as the heat of vaporization, the photovoltaic power generation panel 1 is cooled, and the photovoltaic power generation panel 1 The decrease in power generation efficiency in can be suppressed.
上記構成によれば、太陽光発電パネル１の裏面側に導水材６が設けられるため、太陽光発電パネル１および導水材６の全体の設置面積が大きくなり、全体の設置面積に占める太陽光発電パネル１の設置面積が小さくなってしまことがない。
According to the said structure, since the water guide material 6 is provided in the back surface side of the photovoltaic power generation panel 1, the installation area of the whole photovoltaic power generation panel 1 and the water guide material 6 becomes large, and the photovoltaic power generation which occupies for the whole installation area The installation area of panel 1 is never reduced.

In attaching the photovoltaic power generation panel 1 to the panel attachment member 2, first, the frame material body 13 is attached to the attachment member body 21. Next, the moisture-permeable holding member 40 and the first water-absorbing member 4 are placed on the attachment member body 21 by placing the flange 42 of the moisture-permeable holding member 40 on the support piece 15. Then, the panel main body 11 is placed on the flange 42, and finally, the pressing piece 14 is fixed to the frame material main body 13 to complete. The fixing of the pressing piece 14 to the frame material main body 13 is not particularly limited, such as fitting and fixing with the screw 41.
これにより、透湿性保持部材４０および第一の吸水性部材４が後付けで取り付け可能となる。すなわち、押さえ片１４が枠材本体１３から離脱されて、パネル本体１１が取り外され、次に、上記のように透湿性保持部材４０および第一の吸水性部材４が取付部材本体２１に取り付けられて、後付けがなされる。
Thereby, the moisture-permeable holding member 40 and the first water absorbing member 4 can be attached later. That is, the pressing piece 14 is detached from the frame body 13 and the panel body 11 is removed. Next, the moisture-permeable holding member 40 and the first water absorbing member 4 are attached to the attachment member body 21 as described above. After that, it will be retrofitted.
