そして、図２および図３から明らかなように、太陽電池パネル本体12の本体板部15の表面と、周枠体13の上端部挟持部31の上端部表面側挟持板41の表面と、周枠体13の下端部挟持部32の下端部表面側挟持板51の表面と、周枠体13の左端部挟持部33の左端部表面側挟持板61の表面と、周枠体13の右端部挟持部34の右端部表面側挟持板71の表面とが、同一平面上に位置している。   2 and 3, the surface of the main body plate portion 15 of the solar cell panel body 12, the surface of the upper end portion surface side clamping plate 41 of the upper end portion clamping portion 31 of the peripheral frame body 13, The surface of the lower end surface side clamping plate 51 of the lower end portion clamping part 32 of the frame 13, the surface of the left end surface side clamping plate 61 of the left end clamping part 33 of the peripheral frame 13, and the right end of the peripheral frame 13 The surface of the right end surface side clamping plate 71 of the clamping part 34 is located on the same plane.

つまり、表面側挟持板41，51，61，71の厚さ寸法と凹み部分16，18，21，23の深さ寸法とが同じであり、これらの各表面側挟持板41，51，61，71は本体板部15の表面に対して非突出の状態となっており、太陽電池パネル11の表面全体が凹凸のない平坦な平面11aにて構成されている。   That is, the thickness dimension of the front side clamping plates 41, 51, 61, 71 is the same as the depth dimension of the recessed portions 16, 18, 21, 23, and each of these front side clamping plates 41, 51, 61, 71 is in a non-projecting state with respect to the surface of the main body plate portion 15, and the entire surface of the solar cell panel 11 is constituted by a flat plane 11a having no irregularities.

なお、太陽電池パネル11の上下方向長さ寸法は例えば７００〜８００ｍｍ、太陽電池パネル11の左右方向長さ寸法は例えば１４００〜１６００ｍｍである。   In addition, the vertical dimension of the solar cell panel 11 is 700 to 800 mm, for example, and the horizontal dimension of the solar cell panel 11 is 1400 to 1600 mm, for example.

次に、太陽電池パネル11の作用等を説明する。   Next, the operation and the like of the solar cell panel 11 will be described.

図４および図５には、太陽電池パネル11の使用状態（横置きの設置例）が示されている。   4 and 5 show the usage state of the solar cell panel 11 (horizontal installation example).

この例では、複数枚、例えば６枚の太陽電池パネル11が上下２段で水平方向に３つ並べられて互いに連結されて１枚の平板状の太陽電池パネル部81が構成されている。   In this example, a plurality of, for example, six solar cell panels 11 are horizontally arranged in two upper and lower stages and connected to each other to form one flat solar cell panel portion 81.

この太陽電池パネル部81は、パネル支持部82を介して、建物の屋根83の上に水平方向に対して傾斜した傾斜状態となって設置されている。なお、太陽電池パネル11の水平方向に対する傾斜角度は、太陽光を効率的に受けることができる最適な角度、すなわち例えば３０度である。   The solar cell panel portion 81 is installed on the roof 83 of the building in an inclined state inclined with respect to the horizontal direction via the panel support portion 82. The inclination angle of the solar cell panel 11 with respect to the horizontal direction is an optimum angle at which sunlight can be received efficiently, that is, for example, 30 degrees.

そして、この使用場所が例えば北海道や東北等の積雪地帯であり、冬期間に雪が降ると、その雪は、図５に示されるように、例えば夜のうちに、太陽電池パネル11の表面上に積もる。   And this place of use is a snowy area such as Hokkaido or Tohoku, and if it falls during the winter period, the snow is on the surface of the solar cell panel 11 at night as shown in FIG. Pile up.

しかし、太陽が昇り、気温が上昇すると、太陽電池パネル11の表面上の積雪は、解け始め、太陽電池パネル11の傾斜状の表面上から滑り落ちる。このため、太陽電池パネル本体12の表面上に積雪が残らず、太陽電池パネル本体12の表面の一部が雪で覆われて影になるようなことがない。つまり、太陽電池パネル11では、使用場所が積雪地帯であっても、雪の悪影響を受けない。   However, when the sun rises and the temperature rises, snow on the surface of the solar cell panel 11 starts to melt and slides down from the inclined surface of the solar cell panel 11. For this reason, no snow is left on the surface of the solar cell panel body 12, and a part of the surface of the solar cell panel body 12 is not covered with snow and becomes a shadow. That is, the solar cell panel 11 is not adversely affected by snow even when the place of use is in a snowy area.

また、例えば風の強い日に、太陽電池パネル11の裏面に強い風圧力が作用しても、太陽電池パネル本体12が周枠体13から外れることがなく、周枠体13が破損することもない。   Further, for example, even if a strong wind pressure acts on the back surface of the solar cell panel 11 on a windy day, the solar cell panel body 12 is not detached from the peripheral frame body 13 and the peripheral frame body 13 may be damaged. Absent.

そして、このような太陽電池パネル11によれば、例えば北海道や東北等の積雪地帯で使用され、冬期間に雪が降っても、従来の構成とは異なり、太陽電池パネル11の表面が凹凸のない平坦な平面11aにて構成されているため、太陽電池パネル本体12の表面上に積もった雪は、この太陽電池パネル本体12の周端部を保持した周枠体13には引っ掛らず、その太陽電池パネル本体12の表面上からスムーズに落下するため、積雪地帯の冬期間においても太陽光エネルギを電気エネルギに適切に変換することができ、エネルギ変換効率（発電効率）の向上を図ることができる。すなわち例えば発電効率は、年間で１０〜２０％程度上昇し、エネルギ不足に貢献できる。   And according to such a solar cell panel 11, for example, it is used in snowy areas such as Hokkaido and Tohoku, and even if it snows during the winter period, unlike the conventional configuration, the surface of the solar cell panel 11 is not uneven. Because it is composed of a flat surface 11a, the snow accumulated on the surface of the solar cell panel body 12 does not get caught in the peripheral frame 13 that holds the peripheral edge of the solar cell panel body 12, Since it falls smoothly from the surface of the solar cell panel body 12, solar energy can be appropriately converted into electric energy even in the snowy winter season, and energy conversion efficiency (power generation efficiency) can be improved. Can do. That is, for example, the power generation efficiency increases by about 10 to 20% annually, which can contribute to energy shortage.

特に、太陽電池パネル本体12の本体板部15の表面と、周枠体13の上端部挟持部31の上端部表面側挟持板41の表面と、周枠体13の下端部挟持部32の下端部表面側挟持板51の表面と、周枠体13の左端部挟持部33の左端部表面側挟持板61の表面と、周枠体13の右端部挟持部34の右端部表面側挟持板71の表面とが、同一平面上に位置するため、太陽電池パネル本体12上の積雪をより一層スムーズに落下させることができる。   In particular, the surface of the main body plate portion 15 of the solar cell panel body 12, the surface of the upper end surface sandwiching plate 41 of the upper end portion sandwiching portion 31 of the peripheral frame 13, and the lower end of the lower end sandwiching portion 32 of the peripheral frame 13 The surface of the part surface side clamping plate 51, the surface of the left end part surface side clamping plate 61 of the left end part clamping part 33 of the peripheral frame 13, and the right end surface side clamping plate 71 of the right end part clamping part 34 of the peripheral frame 13 Therefore, the snow on the solar cell panel body 12 can be dropped more smoothly.

また、周枠体13が、凹み付上端部17を表裏面側から挟持する断面コ字状の上端部挟持部31と、凹み付下端部19を表裏面側から挟持する断面コ字状の下端部挟持部32と、凹み付左端部22を表裏面側から挟持する断面コ字状の左端部挟持部33と、凹み付右端部24を表裏面側から挟持する断面コ字状の右端部挟持部34とを有する構成であるから、例えば積雪荷重および風圧力に十分に耐え得る強度を適切に確保することができ、使用場所の制限を受けにくい。   In addition, the peripheral frame 13 has a U-shaped upper end clamping portion 31 that clamps the recessed upper end portion 17 from the front and back sides, and a U-shaped sectional lower end that clamps the recessed lower end portion 19 from the front and back sides. A sandwiching part 32, a U-shaped left end sandwiching part 33 that grips the recessed left end 22 from the front and back sides, and a U-shaped crossing right end sandwiching the recessed right end 24 from the front and back sides Therefore, for example, the strength sufficient to withstand snow load and wind pressure can be appropriately ensured, and the place of use is not easily restricted.

さらに、例えば設置場所等に応じて９０度回して左右方向を上下方向に変えて使用することもできる。すなわち例えば図６に示すように、細長い建物の屋根83の上に設置する場合には、左右方向を上下方向にした太陽電池パネル11を水平方向に６つ並べて互いに連結して１枚の平板状の太陽電池パネル部81を構成し、この構成した太陽電池パネル部81をパネル支持部82を介して建物の屋根83の上に傾斜状態にして設置する。このように太陽電池パネル11を縦置きに設置しても、図４および図５に示すように横置きに設置した場合と同様の作用効果を奏することができる。   Furthermore, for example, it can be used by turning 90 degrees according to the installation location or the like to change the left-right direction to the up-down direction. That is, for example, as shown in FIG. 6, when installing on the roof 83 of a long and narrow building, six solar cell panels 11 with the left and right direction being the vertical direction are arranged in a horizontal direction and connected to each other to form a single flat plate shape. The solar cell panel portion 81 is constructed, and the constructed solar cell panel portion 81 is installed in an inclined state on the roof 83 of the building via the panel support portion 82. Thus, even if the solar cell panel 11 is installed vertically, the same operational effects as when installed horizontally as shown in FIGS. 4 and 5 can be obtained.

なお、太陽電池パネル本体12は、強度向上のために、例えば図７に示すように、強化ガラス26内にこの強化ガラス26の全体にわたって位置するように埋設された網状の補強部材である補強網91を有するものでもよい。補強網91は、例えば金属や樹脂、或いはカーボン等の特殊繊維からなるものである。   In order to improve the strength, the solar cell panel main body 12 is a reinforcing net which is a net-like reinforcing member embedded in the tempered glass 26 so as to be located throughout the tempered glass 26 as shown in FIG. It may have 91. The reinforcing net 91 is made of a special fiber such as metal, resin, or carbon.

そして、補強網91は、本体板部15内に埋設された１枚状の本体板部内網部92と、凹み付上端部17内に埋設された複数枚状（例えば２枚状）の上端部内網部93と、凹み付下端部19内に埋設された複数枚状（例えば２枚状）の下端部内網部94と、凹み付左端部22内に埋設された複数枚状（例えば２枚状）の左端部内網部（図示せず）と、凹み付右端部24内に埋設された複数枚状（例えば２枚状）の右端部内網部（図示せず）とにて構成されている。   The reinforcing net 91 includes a single main plate inner net 92 embedded in the main plate 15 and a plurality of (for example, two) upper ends embedded in the recessed upper end 17. A net 93, a plurality of (for example, two) bottom end nets 94 embedded in the recessed lower end 19, and a plurality of (for example, two) embedded in the recessed left end 22 ) In the left end portion net (not shown) and a plurality of (for example, two) right end portion nets (not shown) embedded in the recessed right end portion 24.

なお、例えば図示しないが、補強網91は、本体板部15内および４つの各端部17，19，22，24内に埋設された１枚状の網部のみで構成されたもの等でもよい。   For example, although not shown, the reinforcing net 91 may be configured by only a single net portion embedded in the main body plate portion 15 and in each of the four end portions 17, 19, 22, and 24. .

また、太陽電池パネル本体12を補強するための補強部材は、網状の補強網91には限定されず、他の形状のものでもよい。   In addition, the reinforcing member for reinforcing the solar cell panel body 12 is not limited to the net-like reinforcing net 91, and may have other shapes.

さらに、太陽電池パネル本体12の強度向上のために、太陽電池パネル本体12の裏面に例えば格子状の凹凸部等を形成してもよい。   Further, in order to improve the strength of the solar cell panel body 12, for example, a lattice-shaped uneven portion may be formed on the back surface of the solar cell panel body 12.

また、表面側挟持板41，51，61，71の厚さ寸法と凹み部分16，18，21，23の深さ寸法とが同じである構成には限定されず、例えば表面側挟持板41，51，61，71の厚さ寸法が凹み部分16，18，21，23の深さ寸法よりも小さく、表面側挟持板41，51，61，71が本体板部15の表面より突出しない構成でもよい。   Further, the thickness dimension of the front side clamping plates 41, 51, 61, 71 and the depth dimension of the recessed portions 16, 18, 21, 23 are not limited to the configuration, for example, the front side clamping plate 41, Even if the thickness dimension of 51, 61, 71 is smaller than the depth dimension of the recessed portions 16, 18, 21, 23, and the front side clamping plates 41, 51, 61, 71 do not protrude from the surface of the main body plate portion 15. Good.
