この種の太陽光発電・蓄電装置を示す従来の技術の例としては、図８、図９に示す特開２０１１−１２４８７０号公開特許公報に開示された技術がある。
これについて説明すれば、図８に於いて家屋の屋根Ａには、太陽光６を受けて発電をする太陽光パネル１が設けられている。太陽光パネル１が発電した電力は、蓄電池２に蓄積される。電力制御装置３には、太陽光パネル１、蓄電池２および系統電力４から電力が供給される。家屋の内部には負荷としての例えば、液晶テレビ５が設けられており、電力制御装置３が液晶テレビ５に電力を供給する。As an example of the prior art which shows this kind of solar power generation and electrical storage apparatus, there exists a technique disclosed by Unexamined-Japanese-Patent No. 2011-124870 shown to FIG. 8, FIG.
If this is demonstrated, in FIG. 8, the roof A of a house is provided with the solar panel 1 which receives the sunlight 6 and generates electric power. The power generated by the solar panel 1 is stored in the storage battery 2. Electric power is supplied to the power control device 3 from the solar panel 1, the storage battery 2 and the grid power 4. For example, a liquid crystal television 5 is provided inside the house as a load, and the power control device 3 supplies power to the liquid crystal television 5.
従来の技術では、太陽光パネル１で発電した電力は再利用可能電力であり、また石油などの枯渇性資源で発電された電力を枯渇性電力である。液晶テレビ５は、供給可能な再利用可能電力が変化した場合、その機能の数または機能の品質を変更するものとする。家屋は、系統電力（商用電力）４の供給を受けることも可能である。In the prior art, the power generated by the solar panel 1 is reusable power, and the power generated by a depletable resource such as oil is a depletable power. It is assumed that the liquid crystal television 5 changes the number of functions or the quality of functions when the available reusable power changes. The house can also receive the supply of the grid power (commercial power) 4.
図９は、図８を説明するエコシステムの概略構成を示すブロック図である。電力制御装置３には、前記３つの電力源から電力が供給される。具体的には、太陽光パネル１、蓄電池２および系統電力４である。太陽光パネル１は、太陽光発電など再利用可能エネルギーを生成する。再利用可能エネルギーは、石油などの枯渇性資源を用いずに発電した電力であり、クリーンエネルギーと呼ぶこともある。そして、電力制御装置３の電力入力部に送電する。そして、電力制御装置３の電力入力部に送電する。蓄電池２は、クリーンエネルギーを蓄積する。系統電力４は、火力発電など、枯渇性資源を用い、また二酸化炭素など地球温暖化に影響のある方法を用いて発電される電力源である。また液晶テレビ５は電力情報受信部や電源部を備え電力制御装置３からの信号を受信する。ところで太陽光パネル１による発電したエネルギーは蓄電池２に蓄積されるが、その技術は太陽光６が直接に太陽光パネル１に放射され発電・蓄積されるものである。FIG. 9 is a block diagram showing a schematic configuration of the ecosystem for explaining FIG. The power control device 3 is supplied with power from the three power sources. Specifically, the solar panel 1, the storage battery 2, and the grid power 4. The solar panel 1 generates reusable energy such as solar power generation. Reusable energy is electric power generated without using depletable resources such as petroleum, and may be called clean energy. Then, power is transmitted to the power input unit of the power control device 3. Then, power is transmitted to the power input unit of the power control device 3. The storage battery 2 stores clean energy. The grid power 4 is a power source generated using a depletable resource such as thermal power and using a method having an influence on global warming such as carbon dioxide. In addition, the liquid crystal television 5 includes a power information receiving unit and a power supply unit, and receives a signal from the power control device 3. By the way, although the energy generated by the solar panel 1 is stored in the storage battery 2, the technology is that solar light 6 is directly radiated to the solar panel 1 to generate and store electric power.

以下、本発明に係る太陽光発電・蓄電装置の実施の形態について、添付図面に基づき詳細に説明する。Hereinafter, embodiments of a solar power generation and storage device according to the present invention will be described in detail based on the attached drawings.
図１は、太陽光発電・蓄電装置の実施の形態を示す全体構成図である。これについて説明すれば、７は例えば、湾曲ドーム状である太陽光波長変換部であり、太陽光６を入光し、図２に示すように発熱作用により発電に有効でない発電効率を低下させる紫外線波長や近紫外線、中紫外線波長の各領域にある太陽光スペクトルＢを可視光領域に変換させる機能を有する。そこで図２で明らかなように太陽光６は分布波長領域によって紫外線、可視光線、近赤外線及び中赤外線から構成され、太陽光スペクトルＢを形成している。前記太陽光波長変換部７により太陽光６を図２に示す斜線部分を切断し可視光領域や発電に有効な領域の波長に変換する。FIG. 1 is an overall configuration diagram showing an embodiment of a photovoltaic power generation and storage device. If this is described, for example, 7 is a curved dome-like solar light wavelength converter, and it is an ultraviolet light which enters sunlight 6 and reduces the power generation efficiency which is not effective for power generation due to the heat generation as shown in FIG. It has a function of converting the sunlight spectrum B in each of the wavelength, near-ultraviolet, and mid-ultraviolet wavelengths into the visible light region. Therefore, as is apparent from FIG. 2, the sunlight 6 is composed of ultraviolet light, visible light, near infrared light, and mid infrared light depending on the distribution wavelength region to form a sunlight spectrum B. The sunlight wavelength converter 7 cuts the hatched portion shown in FIG. 2 into sunlight 6 and converts it into a visible light region or a wavelength of a region effective for power generation.
前記太陽光波長変換部７は湾曲ドーム状であって全角度から入光される太陽光６を反射させることなく自然太陽光から太陽電池発電用太陽光に変換させ採光することが可能となり、例えば平面形状の如き太陽光波長変換部７であれば太陽光６を不必要に反射させることが多い。そして、該太陽光波長変換部７は風雨の影響を受け難い構造とし、その表面は砂塵や汚れが付着することが極めて少ないという特質がある。図２は太陽光６の各波長領域の光波長値（ｎｍ）に対する分光放射照度値（Ｌｘ／ｎｍ）を示す。図中、太陽光スペクトルＢ及び単結晶太陽電池分光感度Ｃを示すものである。The sunlight wavelength conversion unit 7 has a curved dome shape, and it is possible to convert natural sunlight into sunlight for solar cell power generation and reflect it without reflecting the sunlight 6 incident from all angles, for example, In the case of a sunlight wavelength conversion unit 7 such as a flat shape, the sunlight 6 is often reflected unnecessarily. The sunlight wavelength conversion unit 7 has a structure that is not easily affected by wind and rain, and the surface thereof has the characteristic that dust and dirt do not adhere very much. FIG. 2 shows the spectral irradiance value (Lx / nm) with respect to the light wavelength value (nm) of each wavelength region of the sunlight 6. In the figure, a solar light spectrum B and a single crystal solar cell spectral sensitivity C are shown.
８は太陽光自動追尾採光部であり、前記太陽光波長変換部７の底部に装着してあり、その構成は図３に示してあり、太陽光反射フィン８ａと、太陽光センサー（図示せず）と、駆動部材８ｂとで成る。太陽光反射フィン８ａの角度を入光高度に適合させて駆動部材８ｂで自動調整して、前記太陽光波長変換部７から入光された太陽光６を追尾する。６ａは太陽光自動追尾採光部８から出る太陽光であり、常に制御されて垂直方向に出光する。The reference numeral 8 denotes a sunlight automatic tracking light collection unit, which is attached to the bottom of the sunlight wavelength conversion unit 7, the configuration of which is shown in FIG. 3, a sunlight reflection fin 8a and a sunlight sensor (not shown) And a driving member 8b. The angle of the sunlight reflection fin 8a is adapted to the incident light height and automatically adjusted by the drive member 8b, and the sunlight 6 inputted from the sunlight wavelength conversion unit 7 is tracked. Reference numeral 6a denotes sunlight emitted from the sunlight automatic tracking and lighting unit 8, which is constantly controlled to emit light in the vertical direction.
一つの例として太陽光自動追尾採光部８は低緯度地域向け、いわゆる赤道直下地域向けの装置がある。この装置は前記太陽光反射フィン８ａは円滑な表面処理施こしており、反射損を極力少なくし、太陽光反射効率を９５％以上に高める機能を備えている。そして、太陽光波長変換部７が破損した場合に中赤外線波長等が、入光されて来たとき、温度を検知する。太陽光遮断位置に太陽光反射フィン８ａが稼働し太陽光６を遮断する。そして、偏光反射部１０や導光板積層発電部１１等の保護を行う。図３（ａ）ないし（ｅ）は太陽光自動追尾採光部８に備えた太陽光反射フィン８ａの可動領域を示すものであり、例えば、東方角度＋３０°つまり入光高度＋３０°から西方角度−３０°、つまり入光高度−３０°、までの例示である。実際には東方＋２０°から西方−２０°の可動領域を実現できる。この太陽光自動追尾採光部８は太陽の日の出０°から太陽の日没−０°まで追尾可能である。 As one example, there is a device for automatic tracking and lighting unit 8 for low-latitude regions, that is, a so-called region immediately below the equator. In this device, the solar light reflection fins 8a are subjected to a smooth surface treatment, and have a function of minimizing the reflection loss and increasing the solar light reflection efficiency to 95% or more. Then, when the sunlight wavelength conversion unit 7 is broken and the mid-infrared wavelength or the like is incident, the temperature is detected. The sunlight reflecting fin 8 a operates at the sunlight blocking position to block the sunlight 6. And protection of the polarization reflection part 10, the light guide plate lamination | stacking electric power generation part 11, etc. is performed. FIGS. 3 (a) to 3 (e) show the movable region of the sunlight reflecting fin 8a provided in the sunlight automatic tracking and collecting unit 8. For example, the east angle + 30 °, that is, the light incidence altitude + 30 ° to the west angle − It is an example up to 30 °, that is, to a light entrance height of -30 °. In practice, a movable range of east + 20 ° to west 20 ° can be realized. This sunlight automatic tracking and lighting unit 8 can track from 0 ° of the sunrise of the sun to 0 ° of the sunset of the sun.
太陽光自動追尾採光部８の他の例としては高緯度地域向けいわゆる赤道直下地域以外向け装置がある。この装置は太陽光の入光高度の変化が大きい場合に太陽光の採光を可能にする。太陽光入光高度に適合させ太陽光反射フィン８ａを駆動し、出光する太陽光６ａを常に垂直に偏光させる。As another example of the sunlight automatic tracking and lighting unit 8, there is a device for high latitude areas other than the area just below the equator. This device makes it possible to collect sunlight when the change in the incident light height of sunlight is large. The solar light reflection fin 8a is driven by adapting to the sunlight incident altitude, and the outgoing sunlight 6a is always polarized vertically.
図３について詳しく説明すれば、図３は太陽光自動追尾採光部８の各可動領域を示した詳細な図である。
（ａ）は太陽光自動追尾採光部８の太陽光反射フィン８ａが太陽光入光高度が３０°つまり太陽の位置が真東から３０°に上昇したとき、太陽光反射フィン８ａを６０°に調整した状態を示す。そして太陽光自動追尾採光部８から出た太陽光６ａは下段の太陽光導光ダクト部９や偏光反射部１０に導びかれる。If FIG. 3 is demonstrated in detail, FIG. 3 is a detailed figure which showed each movable area | region of the sunlight automatic tracking light-collection part 8. As shown in FIG.

The state adjusted to 90 ° is shown. And the sunlight 6a which came out of the sunlight automatic tracking light collection part 8 is guide | induced to the sunlight light guide duct part 9 and the polarization reflection part 10 of a lower stage.
（ｄ）は太陽光自動追尾採光部８の太陽光反射フィン８ａが太陽光入光高度が−６０°つまり太陽の位置が真西から−６０°に傾斜したとき、太陽光反射フィン８ａを−７５°に調整した状態を示す。そして太陽光自動追尾採光部８から出た太陽光６ａは下段の太陽光導光ダクト部９や偏光反射部１０に導びかれる。(D) is the sunlight reflection fin 8a of the sunlight tracking part 8 when the sunlight incident height is -60 °, that is, when the position of the sun is inclined to -60 ° from the west, The state adjusted to 75 ° is shown. And the sunlight 6a which came out of the sunlight automatic tracking light collection part 8 is guide | induced to the sunlight light guide duct part 9 and the polarization reflection part 10 of a lower stage.
（ｅ）は太陽光自動追尾採光部８の太陽光反射フィン８ａが太陽光入光高度が−３０°つまり太陽の位置が真西から３０°に傾斜したとき、太陽光反射フィン８ａを−６０°に調整した状態を示す。そして太陽光自動追尾採光部８から出た太陽光６ａは下段の太陽光導光ダクト部９や偏光反射部１０に導びかれる。In (e), when the sunlight reflection fin 8a of the sunlight tracking portion 8 has a sunlight incidence height of -30 °, that is, when the position of the sun is inclined 30 ° from the west, the sunlight reflection fin 8a is -60 The state adjusted to ° is shown. And the sunlight 6a which came out of the sunlight automatic tracking light collection part 8 is guide | induced to the sunlight light guide duct part 9 and the polarization reflection part 10 of a lower stage.
上述は太陽光自動追尾採光部８の動作範囲を示すものであるが、前記太陽光反射フィン８ａの可動領域は太陽の位置が真東から２０°の上昇位置ないし真西から−２０°の傾斜位置まで追尾可能である。The above description shows the operation range of the automatic tracking and light collecting unit 8 of the sunlight, but the movable region of the sunlight reflecting fin 8a is inclined at an elevation of 20 ° from the east to the elevation of −20 ° from the east It is possible to track to the position.
９は太陽光導光ダクト部であり、全体形状が略円錐形状又は略四角錐形状でなる。その上端採光縁９ａは前記太陽光自動追尾採光部８の下側に連結・装着し、またその下端縁９ｂは発電ダクト１１Ａに連結する。前記太陽光導光ダクト部９の寸法形状を例示すれば、上端採光縁９ａの幅長Ｗ１、太陽光導光ダクト部９の高さＨ、下端縁９ｂの幅長Ｗ２である場合、Ｗ１＝１、Ｈ＝１、Ｗ２＝０．３ないし０．５の比率に設定すると共に太陽光導光ダクト部９の採光集光角度θ１は６５°ないし８０°であり、集束集光角θ２は１５５°ないし１７０°であると効率よく太陽光６ａを次段の偏光反射部１０に反射入光することができる。A solar light guide duct portion 9 has a substantially conical shape or a substantially square pyramidal shape as a whole. The upper end lighting edge 9a is connected to and mounted on the lower side of the automatic tracking light emitting unit 8 and the lower end edge 9b is connected to the power generation duct 11A. If the dimensions and shape of the solar light guide duct portion 9 are exemplified, if the width length W 1 of the upper end lighting edge 9 a, the height H of the solar light guide duct portion 9 and the width length W 2 of the lower end edge 9 b, W 1 = 1, H = 1, W 2 = 0.3 to 0.5, and the light collection angle θ 1 of the light guide duct portion 9 is 65 ° to 80 °, and the light collection angle θ When 2 is 155 ° to 170 °, the sunlight 6a can be efficiently reflected and incident on the polarization reflecting portion 10 in the next stage.
該太陽光導光ダクト部９の内表面は表面処理を行ない、入光した太陽光６ａを９５％以上の反射効率にすることができる。そして、該太陽光導光ダクト部９の材料はアルミニューム板、ＳＵＳ板、鋼板等で形成する。本来、後述する導光板積層発電部１１に強大かつ多光量の太陽光６を導入することが必要である。このためには、前述した上端採光縁９ａの幅長Ｗ１を例えば下端縁９ｂの幅長Ｗ２に対して２ないし３．３倍にすることが考えられるが、太陽光導光ダクト部９に反射する回数を極力少なく例えば１回にすることが最適値となる。この最適値であれば入光する太陽光６ａはその照度を概ね６倍程度に上昇・集束して太陽光導光ダクト部９は導光板積層発電部１１に入光できる。The inner surface of the solar light guide duct portion 9 is subjected to surface treatment so that the incident sunlight 6a can have a reflection efficiency of 95% or more. And the material of this solar light guide duct part 9 is formed with an aluminum board, a SUS board, a steel plate etc. Essentially, it is necessary to introduce a strong and large amount of sunlight 6 into a light guide plate laminated power generation unit 11 described later. For this purpose, it is conceivable to increase the width W 1 of the upper end light collecting edge 9 a to, for example, 2 to 3.3 times the width W 2 of the lower end 9 b. It is optimal to minimize the number of reflections, for example, once. With this optimal value, the incident sunlight 6a rises and converges its illuminance by approximately six times, and the sunlight guiding duct portion 9 can enter the light guiding plate laminated power generation portion 11.
ここで、１０は偏光反射部であって、発電ダクト１１Ａ内に収容されている。そして、太陽光導光ダクト部９の下段に装着され、前記導光板積層発電部１１の上端に設置された略三角形状で構成され一つの内角θ３を有した反射板で構成される。該偏光反射部１０は太陽光導光ダクト部９から入光した太陽光６ａを屈折させながら下方に設置した導光板積層発電部１１に有効に採光させる。すなわち偏光反射部１０が存在しない場合は、太陽光導光ダクト部９から入光した太陽光６ａは該導光板積層発電部１１に入光することなく導光板積層発電部１１の上端（天面）で反射され、集束することができない。このため、内角θ３が例えば５０°ないし７０°の範囲に設定した偏光反射部１０を備え図１に示すように入光した太陽光６ａを偏光反射部１０により屈折させながら屈折光６ｂとして導光板積層発電部１１に入光させる。偏光反射部１０の素材は鋼板、鏡、プリズム、ガラス等の材質でなる。尚、偏光反射部１０の反射率は９５％確保できる。Here, reference numeral 10 denotes a polarization reflector, which is accommodated in the power generation duct 11A. And it is equipped with the lower stage of the sunlight light guide duct part 9, and it is comprised in the substantially triangular shape installed in the upper end of the said light-guide plate lamination | stacking electric power generation part 11, and is comprised with the reflecting plate with one interior angle (theta) 3 . The polarized light reflection section 10 effectively makes the light guide plate laminated power generation section 11 installed below the light guide plate power generation section 11 refracting the sunlight 6a incident from the sunlight light guide duct section 9. That is, when the polarization reflection portion 10 does not exist, the sunlight 6a incident from the solar light guide duct portion 9 does not enter the light guide plate laminated power generation portion 11, and the upper end (top surface) of the light guide plate laminated power generation portion 11 Reflected and can not be focused. Therefore, guiding the sunlight 6a which is incident as shown in the inner angle theta 3 equipped with a polarizing reflector unit 10 which is set in a range of, for example, 50 ° to 70 ° Figure 1 as the refracted light 6b while refracted by the polarizing reflective portion 10 The light plate laminated power generation unit 11 is made to enter. The material of the polarization reflection unit 10 is made of a material such as a steel plate, a mirror, a prism, glass or the like. In addition, 95% of the reflectance of the polarization reflection part 10 can be ensured.
次に、前記導光板積層発電部１１について説明する。
該導光板積層発電部１１は前記発電ダクト１１Ａ内に収容され、前記偏光反射部１０から集光された屈折光６ｂを図４（ａ）（ｂ）に示すように導光板１１ｃ、１１ｉのエッヂ部分１１ｆ、１１ｍから採光させ又はユニット間隔Ｗ３から採光させ導光板１１ｃ、１１ｉと太陽電池パネル１１ｂ、１１ｄ、１１ｈ、１１ｊで発電作用を行う。そして、導光板積層発電部１１は、図１のＤ部で示すものであって、偏光反射部１０の下方に配置してある。Ｄ部の構成は図４（ａ）及び図４（ｂ）に示してある。Next, the light guide plate laminated power generation unit 11 will be described.

The light guide plate laminated power generation unit 11 is shown by D in FIG. 1 and is disposed below the polarization reflection unit 10. The configuration of the D portion is shown in FIGS. 4 (a) and 4 (b).
２つ例示してある構造はいずれも三つの組を重設した構成であり、実施するに当っては一つの組の構成でもよい。図４（ａ）に示す導光板積層発電部１１の一つの組の構成としては、第１層としての絶縁しゃ断板１１ａと、第２層としての太陽電池パネル１１ｂと、第３層としての導光板１１ｃ、第４層としての太陽電池パネル１１ｄと、第５層としての絶縁しゃ断板１１ｅとでなる。ここで前記発電ダクト１１Ａは例えば水平断面形状が円形又は四角形で形成され、全体が筒状になっている。そして、前記太陽光ダクト部９の下端縁９ｂの形状に適合させる。また、前記発電ダクト１１Ａの材料は前記太陽光導光ダクト部９と同一材料及び同一反射効率を備えている。Each of the two illustrated structures has a configuration in which three sets are overlapped, and may be one set in implementation.

Here, the power generation duct 11A has, for example, a circular or square horizontal cross-sectional shape, and the whole has a cylindrical shape. Then, the shape is adapted to the shape of the lower end edge 9 b of the solar light duct portion 9. Further, the material of the power generation duct 11A is the same material and the same reflection efficiency as the sunlight guiding duct portion 9.
また、導光板積層発電部１１の全体形状は前記太陽光導光ダクト部９や発電ダクト１１Ａに適合させ平面形状が円形や四角形などで形成する。図４（ａ）（ｂ）に於いて、前記一つの組に重設するほかの２つの組の構成も同一であり、説明を省略する。Further, the overall shape of the light guide plate laminated power generation unit 11 is adapted to the solar light guide duct portion 9 and the power generation duct 11A, and the planar shape is formed to be circular or square. In FIGS. 4 (a) and 4 (b), the configuration of the other two sets to be stacked in one set is the same, and the description will be omitted.

次に、前述した図４（ａ）の構成に於いて、更に詳しく説明すれば、図４（ａ）に示すものは、第３層（中間層）としての導光板１１ｃはエッヂ部分１１ｆ、すなわち偏光反射部１０から太陽光６ａ、屈折光６ｂを採光する部分１１ｆの端部角度θ４が下向に３０°ないし６０°であり、特に、４５°が好適である。このように構成したので平板形状に比べ広角からの採光を可能にでき、導光板１１ｃの上下に配置している太陽電池パネル１１ｂ、１１ｄに有効に導光させ、効率よく発電機能や蓄電量を向上させる。上記の端部角度θ ４の設定基準は当該導光板積層発電部１１の積層高さや幅長によって決定される。Next, in the configuration of FIG. 4 (a) described above, the light guide plate 11c as the third layer (intermediate layer) has an edge portion 11f, that is, as shown in FIG. 4 (a). End portion angle θ of the portion 11 f for extracting sunlight 6 a and refracted light 6 b from the polarization reflector 104Is downward 30.degree. To 60.degree., Preferably 45.degree. With this configuration, light can be taken from a wide angle compared to a flat plate shape, and light can be efficiently guided to the solar cell panels 11b and 11d disposed above and below the light guide plate 11c to efficiently generate power and store electricity. Improve. Above end angle θ 4The setting standard of is determined by the stacking height and the width of the light guide plate stacked power generation unit 11.
ここで、図４（ａ）に示す導光板積層発電部１１に於ける一つの導光板積層発電部１１の一つの組を構成した拡大図を示す図５（ａ）についてその作用を説明すれば、前記偏光反射部１０から入光した屈折光６ｂ・・・は、導光板１１ｃのエッヂ部分（採光部）１１ｆが例えば４５°にカットしてあり端部角度θ４が４５°で設定し、プリズムレンズ効果を有し、導光板１１ｃの厚い方に屈折光６ｂ・・・が曲折する作用をする。本発明による導光板積層発電部１１は広角度から採光を可能にし、集束機能を高める。Here, the operation will be described with reference to FIG. 5 (a) showing an enlarged view of one light guide plate laminated power generation unit 11 in the light guide plate laminated power generation unit 11 shown in FIG. 4 (a). the polarized reflection portion 10 refracted light 6b · · · which is incident from the edge portion of the light guide plate 11c Yes was cut into (lighting portion) 11f, for example, 45 ° end angle theta 4 is set by 45 °, Has a prism lens effect, and acts to bend refracted light 6b to the thicker side of the light guide plate 11c. The light guide plate laminated power generation unit 11 according to the present invention enables light collection from a wide angle and enhances the focusing function.
図４（ｂ）に示す導光板積層発電部１１の一つの組の構成は第１層としての絶縁しゃ断板１１ｇと、第２層としての太陽電池パネル１１ｈと、第３層としての導光板１１iと、第４層としての太陽電池パネル１１ｊと、第５層としての絶縁しゃ断板１１ｋとでなる。そして、図４（ｂ）に示すものは第３層（中間層）としての導光板１１ｉはエッヂ部分１１ｍすなわち、偏光反射部１０から太陽光６ａを採光するエッジ部分１１ｍの端部角度θ５が上向きに３０°ないし６０°に設定し、特に４５°が好適である。The configuration of one set of the light guide plate laminated power generation unit 11 shown in FIG. 4B is the insulating blocking plate 11g as the first layer, the solar cell panel 11h as the second layer, and the light guide plate 11i as the third layer. And a solar cell panel 11j as a fourth layer, and an insulation cutoff plate 11k as a fifth layer. The third layer as shown in FIG. 4 (b) the light guide plate 11i as (intermediate layer) edge portion 11m that is, the end portion angle theta 5 of the edge portion 11m for lighting sunlight 6a from the polarization reflecting portion 10 The upward direction is set to 30 ° to 60 °, and 45 ° is particularly preferable.
次に、前述した図４（ｂ）の構成に於いて、更に詳しく説明すれば、図４（ｂ）に示すものは、第３層（中間層）としての導光板１１ｉはエッヂ部分１１ｍ、すなわち偏光反射部１０から太陽光６ａ、屈折光６ｂを採光する部分１１ｍの端部角度θ５が上向に３０°ないし６０°であり、特に、４５°が好適である。このように構成したので積層状態や屈折光６ｂの偏光反射状態によって広角からの採光とは異なる水平採光に近似させることが可能にでき、導光板１１ｃは上下に配置している太陽電池パネル１１ｈ、１１ｊに有効に導光させ、効率よく発電機能や蓄電量を向上させる。上記の端部角度θ５の設定基準は当該導光板積層発電部１１の積層高さや幅長によって決定される。Next, in the configuration of FIG. 4 (b) described above, the light guide plate 11i as the third layer (intermediate layer) has an edge portion 11m, that is, as shown in FIG. 4 (b). solar 6a from the polarization reflecting portion 10, a 60 ° to the ends angle theta 5 parts 11m for lighting the refracted light 6b no 30 ° upwards, in particular, 45 ° is suitable.
