More specifically, solar power generation that can transmit light necessary for the growth of agricultural and horticultural crops and efficiently use the remaining light for solar power generation to suppress the temperature rise inside the agricultural and horticultural house. The present invention relates to a system and an agricultural / horticultural house equipped with the system.

When the solar power generation system is installed on the roof or the like of an agricultural / horticultural house, a daylighting solar cell module is used in order to incorporate light necessary for the growth of agricultural / horticultural crops into the house.

A solar cell array is provided, and the daylighting in the building is performed between the solar cells of the solar cell module and / or between the solar cell modules of the solar cell array. In the solar power generation system with a light-shielding / dimming function, and the above-mentioned system, “the solar battery module uses a solar battery cell capable of generating power on both sides, and the solar battery. Joule is a solar power generation system with a light-shielding / dimming function, characterized in that it can generate electric power not only with sunlight incident from the outside but also with light reflected and scattered indoors (Patent Literature). 1). However, even during the cold season, the temperature inside the house rises greatly by introducing light necessary for the growth of agricultural and horticultural crops into the house during sunny days. In the case of agricultural and horticultural crops, such as strawberries and lettuce, which tend to be hindered by raising the temperature, there is no description or suggestion about a method for solving the problem of requiring cooling.

This is because the effect of increasing the temperature inside the house is large.

以下、本発明を実施例により説明するが、本発明はこれに限定されるものではない。 EXAMPLES Hereinafter, although an Example demonstrates this invention, this invention is not limited to this.

実施例１
（１）太陽光発電システムの作成
坪量５００ｇ／ｍ２のコートボール紙を用い、縦３００ｍｍ×横３００ｍｍ×高さ５０ｍｍの浅い直方体形状の紙箱を作成した。次いで上記紙箱の平面の中央に穴を開け、出力０．５Ｗの採光部分を有する両面発電型の結晶シリコン型太陽電池モジュールを、穴を完全に塞ぐように設置した。このとき穴の大きさは、モジュールの大きさに合わせた。更に、上記紙箱の底面の中央に縦２５０ｍｍ×横２５０ｍｍの穴を開け、住友スリーエム株式会社の赤外線反射フィルム「スコッチティントＮａｎｏ９０Ｓ（商品名）」（赤外線反射率４０％、可視光線透過率８８％）を、縦２８０ｍｍ×横２８０ｍｍの大きさに裁断し、穴を完全に塞ぐように、赤外線反射面が紙箱の内側になるようにして貼り付けた。こうして太陽光発電システムを得た。
（２）性能評価
上記で得た太陽光発電システムに設置した太陽電池モジュールの上２０ｃｍの高さから、５０Ｗのレフランプで照射した。全発電量から、表側の発電量を差し引いた裏側の発電量（上記赤外線反射フィルムの反射光による発電量）は１２．９ｍＷ／ｈｒであった。また日本板硝子株式会社の５ｍｍ厚みの熱強化ガラス「ホームタフライト（商品名）」を用い、縦３００ｍｍ×横３００ｍｍ×高さ１０ｍｍの非常に浅い直方体形状の槽を作成し、内部を蒸留水で満たし、その平面上に上記で得た太陽光発電システムを設置し、太陽電池モジュールの上２０ｃｍの高さから、５０Ｗのレフランプで照射したところ、１時間経過後の蒸留水の温度は、スタート時の２３℃が２４℃に少し上昇した。 Example 1
(1) Creation of photovoltaic power generation system Using a coated cardboard having a basis weight of 500 g / m 2 , a shallow rectangular parallelepiped paper box having a length of 300 mm × width of 300 mm × height of 50 mm was created. Next, a hole was made in the center of the plane of the paper box, and a double-sided power generation type crystalline silicon solar cell module having a daylighting portion with an output of 0.5 W was installed so as to completely close the hole. At this time, the size of the hole was adjusted to the size of the module. Further, a hole of 250 mm length × 250 mm width is formed at the center of the bottom of the paper box, and an infrared reflection film “Scotch Tint Nano90S (trade name)” by Sumitomo 3M Limited (infrared reflectance 40%, visible light transmittance 88%). Was cut into a size of 280 mm in length and 280 mm in width, and attached so that the infrared reflecting surface was inside the paper box so as to completely close the hole. Thus, a solar power generation system was obtained.
(2) Performance evaluation It irradiated with the 50W reflex lamp from the height of 20 cm above the solar cell module installed in the solar power generation system obtained above. The back side power generation amount (the power generation amount by the reflected light of the infrared reflective film) obtained by subtracting the front side power generation amount from the total power generation amount was 12.9 mW / hr. Also, using 5mm thick heat-strengthened glass “Home Taflight (trade name)” by Nippon Sheet Glass Co., Ltd., a very shallow rectangular parallelepiped tank 300mm long x 300mm wide x 10mm high is filled with distilled water. When the solar power generation system obtained above was installed on the plane and irradiated with a 50 W reflex lamp from a height of 20 cm above the solar cell module, the temperature of distilled water after 1 hour was 23 ° C rose slightly to 24 ° C.

比較例１
上記赤外線反射フィルムに替えて、赤外線反射率５％、可視光線透過率１５％のスモークフィルムを用いたこと以外は、実施例１と同様に行った。裏側の発電量は１．６ｍＷ／ｈｒであった。また蒸留水の温度は、スタート時の２３℃が３１℃に上昇した。 Comparative Example 1
The same procedure as in Example 1 was performed except that a smoke film having an infrared reflectance of 5% and a visible light transmittance of 15% was used instead of the infrared reflective film. The power generation on the back side was 1.6 mW / hr. The temperature of distilled water increased from 23 ° C. at the start to 31 ° C.

実施例２
蒸留水に替えて、蒸留水にＨＵＮＴＳＭＡＮ株式会社の色素「ＮＯＶＡＣＲＯＮ ＢＬＡＣＫ ＮＮ（商品名）」を０．００２質量％溶解した水溶液（波長５００ナノメートルに吸収率５０％の吸収極大を有す）で上記直方体形状の槽の内部を満たしたこと以外は、全て実施例１と同様に行った。裏側の発電量は１２．１ｍＷ／ｈｒであった。また水溶液の温度は、スタート時の２３℃が２８℃に上昇した。 Example 2
Instead of distilled water, HUNTSMAN Co., Ltd. dye “NOVACRON BLACK NN” (trade name) dissolved in 0.002% by mass in distilled water (having an absorption maximum of 50% absorption at a wavelength of 500 nanometers) All of the operations were the same as in Example 1 except that the inside of the rectangular parallelepiped tank was filled. The power generation on the back side was 12.1 mW / hr. The temperature of the aqueous solution rose from 23 ° C. at the start to 28 ° C.

比較例２
上記赤外線反射フィルムに替えて、赤外線反射率５％、可視光線透過率１５％のスモークフィルムを用いたこと以外は、実施例２と同様に行った。裏側の発電量は０．８ｍＷ／ｈｒであった。また水溶液の温度は、スタート時の２３℃が３３℃に上昇した。 Comparative Example 2
The same procedure as in Example 2 was performed except that a smoke film having an infrared reflectance of 5% and a visible light transmittance of 15% was used instead of the infrared reflective film. The amount of power generation on the back side was 0.8 mW / hr. The temperature of the aqueous solution rose from 23 ° C. at the start to 33 ° C.

実施例１は裏面側も大きな発電量がある。また槽中の蒸留水温度が、比較例１と比較して、僅かに上昇しているだけであることから、これを設置した農園芸用ハウスは内部温度の上昇を抑制できると期待できる。 In Example 1, the rear side also has a large amount of power generation. Moreover, since the distilled water temperature in a tank is only rising slightly compared with the comparative example 1, it can be anticipated that the agricultural and horticultural house in which this is installed can suppress an increase in internal temperature.

実施例２は裏面側も大きな発電量がある。また槽中の水溶液温度が、実施例１よりも上昇していることから、赤外線反射フィルムを透過した可視光線を、更に色素を含む水溶液を透過させることにより、エネルギーを吸収できたことが分かる。従って、波長５００〜６００ナノメートルの光を吸収する装置を備えることにより、ハウス内部温度の上昇は更に小さくできると期待できる。 In Example 2, there is a large amount of power generation on the back side. Moreover, since the aqueous solution temperature in a tank is rising rather than Example 1, it turns out that the energy was able to be absorbed by permeate | transmitting the visible light which permeate | transmitted the infrared reflective film, and also the aqueous solution containing a pigment | dye. Therefore, it can be expected that an increase in the house internal temperature can be further reduced by providing a device that absorbs light having a wavelength of 500 to 600 nanometers.

一方、比較例１、２は裏面側の発電量が非常に小さい。また槽中の蒸留水又は水溶液の温度が大きく上昇していることから、これを設置しても農園芸用ハウス内部の温度上昇を抑制することはできないと判断される。 On the other hand, in Comparative Examples 1 and 2, the power generation amount on the back side is very small. Moreover, since the temperature of the distilled water or aqueous solution in a tank has risen greatly, even if it installs, it is judged that the temperature rise inside the agricultural / horticultural house cannot be suppressed.
