Description

本発明は、太陽光を、電気エネルギー、熱エネルギー、光として利用する技術に関するものである。   The present invention relates to a technology that uses sunlight as electric energy, thermal energy, and light.

従来から太陽光発電パネルと太陽光集光パネルを同一形状に形成し、該同一形状の太陽光発電パネルと太陽光集光パネルを、建物の屋根に形成したパネル設置手段に平面的に並べて設置するものが特許文献１により知られている。   Conventionally, a solar power generation panel and a solar light collection panel are formed in the same shape, and the same shape of the solar power generation panel and the solar light collection panel are arranged side by side on the panel installation means formed on the roof of the building. This is known from US Pat.

この特許文献１に示された従来例は、パネル設置手段に平面的に並べた太陽光発電パネルと太陽光集光パネルにより太陽光を、電気エネルギー、採光として利用している。   The conventional example shown in Patent Document 1 uses sunlight as electric energy and daylighting by a photovoltaic power generation panel and a solar light collecting panel arranged in a plane on a panel installation means.

また、上記従来例は、太陽光発電パネルと太陽光集光パネルを同一形状としているので、設置者の要求に応じて、建物の屋根に形成したパネル設置手段に対する太陽光発電パネルと太陽光集光パネルの設置数の割合を任意に選択できるようになっている。また、同一形状の太陽光発電パネル、太陽光集光パネルをパネル設置手段に設置するので、施工が簡略化し、構造的な連続性が確保できるという特徴を有している。   Further, in the above conventional example, the photovoltaic power generation panel and the solar light collecting panel have the same shape. Therefore, according to the request of the installer, the photovoltaic power generation panel and the solar light collecting panel for the panel installation means formed on the roof of the building are used. The ratio of the number of installed light panels can be arbitrarily selected. Moreover, since the photovoltaic power generation panel and sunlight condensing panel of the same shape are installed in the panel installation means, the construction is simplified and structural continuity can be secured.

しかしながら、上記従来例は、パネル設置手段に太陽光発電パネルと太陽光集光パネルを平面的に並べるだけなので、太陽光を電気エネルギー、光としてしか利用しておらず、未だ十分な太陽光の有効利用がなされていない。   However, in the above conventional example, since the photovoltaic power generation panel and the solar light collecting panel are simply arranged in a plane on the panel installation means, sunlight is used only as electric energy and light, and sufficient solar power is still insufficient. There is no effective use.

また、太陽光発電パネル、太陽光集光パネルをパネル設置手段に平面的に並べて設置しているだけなので、太陽光発電パネル単体、太陽光集光パネル単体では受光した太陽光のエネルギーの一部しか利用できないという問題がある。   In addition, since the photovoltaic power generation panel and the solar condensing panel are only installed in a plane on the panel installation means, a part of the received solar energy is received by the photovoltaic power generation panel alone and the solar condensing panel alone. There is a problem that it can only be used.

更に、パネル設置手段に太陽光発電パネルと太陽光集光パネルを平面的に並べて設置するだけなので、設置する全太陽光発電パネルと全太陽光集光パネルとの合計面積はパネル設置手段における平面の大きさよりも小さい。このため、発電量、集光量は、パネル設置手段の平面の大きさにより制約され、パネル設置手段の平面の大きさが小さい（設置面積が小さい）場合、発電量、集光量とも小さくなってしまうという問題がある。   Further, since the photovoltaic power generation panel and the solar light collecting panel are only installed in a plane on the panel installation means, the total area of all the solar power generation panels and all the solar light collection panels to be installed is the plane in the panel installation means. Is smaller than the size of For this reason, the power generation amount and the light collection amount are restricted by the size of the plane of the panel installation means. When the plane size of the panel installation means is small (the installation area is small), both the power generation amount and the light collection amount are reduced. There is a problem.

本発明は、上記の問題に鑑みて発明したもので、太陽光を電気エネルギー、熱エネルギー、光として有効利用し、パネル設置手段の平面の大きさに制約があっても、発電量や集熱量や集光量を目的に応じて増やすことができる太陽光利用システムを提供するにある。   The present invention has been invented in view of the above problems, and even when solar light is effectively used as electric energy, heat energy, and light, and the plane size of the panel installation means is limited, the amount of power generation and the amount of heat collected It is in providing the solar light utilization system which can increase the amount of condensing according to the objective.

本発明の太陽光利用システムは、光透過性の太陽光発電パネル１と、熱媒流路２を備えた太陽熱吸収パネル３と、太陽光を集光する集光部４及び集光部４で集光した光を外部に取り出す導光路６を備えた太陽光集光パネル５を備える。そして、本発明は、上記太陽光発電パネル１と、太陽熱吸収パネル３と、太陽光集光パネル５を平面視で同じ外形寸法に形成する。また、これらのパネルを平面方向に複数並べて設置可能なパネル設置手段１０を備え、パネル設置手段１０に、所望のパネルを１乃至複数選択して重ねて設置可能であることを特徴とする。   The solar light utilization system of the present invention includes a light-transmitting solar power generation panel 1, a solar heat absorption panel 3 provided with a heat medium flow path 2, a light collecting unit 4 and a light collecting unit 4 for collecting sunlight. A solar light collecting panel 5 including a light guide path 6 for extracting the collected light to the outside is provided. And this invention forms the said photovoltaic power generation panel 1, the solar heat absorption panel 3, and the sunlight condensing panel 5 in the same external dimension by planar view. Further, it is provided with a panel installation means 10 capable of arranging a plurality of these panels in the plane direction, and one or a plurality of desired panels can be selected and installed on the panel installation means 10.

このような構成とすることで、本発明は、太陽光発電パネル１で太陽光を電気エネルギーに変換し、太陽熱吸収パネル３で太陽光を熱エネルギーに変換し、太陽光集光パネル５で太陽光を採光して利用できる。また、パネル設置手段１０に、平面視で同じ外形寸法の太陽光発電パネル１、太陽熱吸収パネル３、太陽光集光パネル５を平面方向に任意に選択して並べ、上下方向に太陽光発電パネル１、太陽熱吸収パネル３、太陽光集光パネル５を一種類又は複数種類重ねて設置できる。これにより、目的に応じて、太陽光発電パネル１、太陽熱吸収パネル３、太陽光集光パネル５の各設置枚数を自由に選択できる。また、パネル設置手段１０に設置する全太陽光発電パネル１と全太陽熱吸収パネル３と全太陽光集光パネル５の合計面積を、パネル設置手段１０における平面の大きさよりも大きくできる。したがって一定の面積で太陽光を受光して電気エネルギー、熱エネルギー、光として利用するに当たって、パネル設置手段における平面の大きさに制約があっても、発電量、集熱量、集光量を増やすことができる。   By setting it as such a structure, this invention converts sunlight into an electrical energy with the photovoltaic power generation panel 1, converts sunlight into a thermal energy with the solar heat absorption panel 3, and is solar with the sunlight condensing panel 5. Light can be used. Moreover, the photovoltaic power generation panel 1, the solar heat absorption panel 3, and the solar light collecting panel 5 having the same outer dimensions in plan view are arbitrarily selected and arranged in the planar direction on the panel installation means 10, and the photovoltaic power generation panel is vertically arranged. 1, the solar heat absorption panel 3 and the sunlight condensing panel 5 can be installed in one or more types. Thereby, according to the objective, each installation number of the photovoltaic power generation panel 1, the solar heat absorption panel 3, and the sunlight condensing panel 5 can be selected freely. Further, the total area of the all-solar power generation panel 1, all-solar heat absorption panel 3 and all-solar light collecting panel 5 installed in the panel installation unit 10 can be made larger than the plane size of the panel installation unit 10. Therefore, when receiving sunlight in a certain area and using it as electric energy, thermal energy, and light, even if there is a restriction on the size of the plane in the panel installation means, the power generation amount, heat collection amount, and light collection amount can be increased. it can.

また、太陽光集光パネル５に、色調が調整可能な発光手段７と、集光する光の色調に応じて発光手段７が発光する光の色を制御する制御手段８を備え、集光する光と、発光手段７で発光する光を合成して、導光路６から外部に取り出すことが好ましい。   Further, the solar light collecting panel 5 is provided with a light emitting means 7 whose color tone can be adjusted and a control means 8 for controlling the color of the light emitted by the light emitting means 7 in accordance with the color tone of the condensed light. It is preferable that the light and the light emitted from the light emitting means 7 are combined and taken out from the light guide 6 to the outside.

これにより、太陽光集光パネル５を一層のみで設置する場合は、集光する光が利用目的と異なる色調であっても、発光手段７で発光する光と合成することで、導光路６から外部に取り出す光の色調を目的とする色調に調整して利用目的に応じた光の有効利用ができる。また、太陽光集光パネル５の上方に太陽光発電パネル１を重ねて設置する場合は、太陽光発電パネル１を透過した光が利用目的と異なる色調の光であったとしても、導光路６から外部に取り出す光の色調を目的とする色調に調整して利用目的に応じた光の有効利用ができる。   Thereby, when installing the sunlight condensing panel 5 by only one layer, even if the light to condense is a color tone different from the purpose of use, by combining with the light emitted by the light emitting means 7, It is possible to effectively use light according to the purpose of use by adjusting the color tone of the light extracted outside to the target color tone. Further, when the photovoltaic power generation panel 1 is installed over the solar light collecting panel 5, even if the light transmitted through the photovoltaic power generation panel 1 is light having a color tone different from the purpose of use, the light guide path 6. By adjusting the color tone of the light extracted from the outside to the target color tone, it is possible to effectively use the light according to the purpose of use.

また、太陽熱吸収パネル３の熱媒流路２の下面側に、光透過性の断熱材９を備えることが好ましい。   Moreover, it is preferable to provide a light-transmissive heat insulating material 9 on the lower surface side of the heat medium flow path 2 of the solar heat absorption panel 3.

このような構成とすることで、太陽熱吸収パネル３における熱エネルギーへの変換効率が向上し、また、熱エネルギーに変換できなかった太陽光を断熱材９で透過させ、透過した太陽光を電気エネルギーや光として利用することができる。   By adopting such a configuration, the conversion efficiency to the thermal energy in the solar heat absorption panel 3 is improved, and the sunlight that could not be converted into the thermal energy is transmitted through the heat insulating material 9, and the transmitted sunlight is converted into the electric energy. And can be used as light.

また、上から順に太陽光発電パネル１、太陽熱吸収パネル３、太陽光集光パネル５を重ね、太陽熱吸収パネル３の熱媒流路２が太陽光発電パネル１の下面に接触するように形成されていることが好ましい。   In addition, the photovoltaic power generation panel 1, the solar heat absorption panel 3, and the solar light collecting panel 5 are stacked in order from the top so that the heat medium flow path 2 of the solar heat absorption panel 3 is in contact with the lower surface of the photovoltaic power generation panel 1. It is preferable.

このような構成とすることで、太陽光発電パネル１から熱媒流路２に吸熱できるため、太陽光発電パネル１を冷却して発電効率を向上すると共に、太陽熱吸収パネル３における熱エネルギーへの変換効率が向上する。   By adopting such a configuration, heat can be absorbed from the solar power generation panel 1 to the heat medium flow path 2, so that the power generation efficiency is improved by cooling the solar power generation panel 1, and the heat energy in the solar heat absorption panel 3 is increased. Conversion efficiency is improved.

また、光透過性の太陽光発電パネル１の下方に少なくとも太陽光集光パネル５を重ね、光透過性の太陽光発電パネル１がグレー系の色であることが好ましい。   In addition, it is preferable that at least a solar light collecting panel 5 is stacked below the light transmissive solar power generation panel 1 so that the light transmissive solar power generation panel 1 has a gray color.

このような構成とすることで、光透過性の太陽光発電パネル１を透過して太陽光集光パネル５で集光された光は自然光の色調が変化せず、導光路６から外部に取り出す光として自然光の色調を維持できる。   By setting it as such a structure, the light which permeate | transmitted the light transmissive solar power generation panel 1 and was condensed with the sunlight condensing panel 5 does not change the color tone of natural light, but takes it out from the light guide path 6 outside. The color tone of natural light can be maintained as light.

また、色素増感型の太陽光発電パネル１であることが好ましい。   In addition, the dye-sensitized solar power generation panel 1 is preferable.

このような構成とすることで、光透過性の太陽光発電パネル１として、発電効率の良い色調で太陽光発電パネル１を用いることができる。   By setting it as such a structure, the solar power generation panel 1 can be used as the light transmissive solar power generation panel 1 with a color tone with good power generation efficiency.

また、光透過性の太陽光発電パネル１に太陽熱吸収パネル３を重ね、光透過性の太陽光発電パネル１が、アモルファス型の太陽光発電パネル１であることが好ましい。   Moreover, it is preferable that the solar heat absorption panel 3 is piled up on the light transmissive solar power generation panel 1, and the light transmissive solar power generation panel 1 is an amorphous solar power generation panel 1.

このような構成とすることで、アモルファス型の太陽光発電パネル１は熱が蓄熱される傾向にあるので、アモルファス型の太陽光発電パネル１に蓄熱された熱を上又は下に重ねる太陽熱吸収パネル３における熱吸収効率が向上する。   By adopting such a configuration, since the amorphous solar photovoltaic panel 1 tends to store heat, the solar heat absorbing panel that superimposes the heat stored in the amorphous solar photovoltaic panel 1 on top or below The heat absorption efficiency in 3 is improved.

本発明は、上記のように構成したので、一つのシステムで太陽光を電気エネルギー、熱エネルギー、光として有効利用できる。また、同じ外形寸法の太陽光発電パネル、太陽熱吸収パネル、太陽光集光パネルの平面方向及び上下方向における設置枚数を選択することで、目的に応じた太陽光の有効利用ができる。また、パネル設置手段に設置する全太陽光発電パネルと全太陽熱吸収パネルと全太陽光集光パネルの合計面積を、パネル設置手段における平面の大きさよりも大きくできる。これにより太陽光の利用効率が向上し、更に、パネル設置手段における平面の大きさに制約があっても、発電量、集熱量、集光量を増やすことができる。   Since the present invention is configured as described above, sunlight can be effectively used as electric energy, thermal energy, and light in one system. Moreover, the effective utilization of sunlight according to the objective can be performed by selecting the installation number in the plane direction and the up-down direction of the photovoltaic power generation panel, the solar heat absorption panel, and the solar light collecting panel having the same outer dimensions. Moreover, the total area of the all-solar power generation panel, all-solar heat absorption panel, and all-sunlight collecting panel installed in the panel installation unit can be made larger than the plane size of the panel installation unit. Thereby, the utilization efficiency of sunlight can be improved, and furthermore, even if there is a restriction on the size of the plane in the panel installation means, it is possible to increase the power generation amount, the heat collection amount, and the light collection amount.

上記３種類のパネルを重ねるには、図６（ａ）のように上から順に太陽光発電パネル１、太陽熱吸収パネル３、太陽光集光パネル５を重ねる場合と、図６（ｂ）のように上から順に太陽熱吸収パネル３、太陽光発電パネル１、太陽光集光パネル５を重ねる場合がある。   In order to stack the above three types of panels, the photovoltaic power generation panel 1, the solar heat absorption panel 3, and the solar light collecting panel 5 are stacked in order from the top as shown in FIG. 6A, and as shown in FIG. 6B. In some cases, the solar heat absorption panel 3, the solar power generation panel 1, and the solar light collecting panel 5 are stacked in order from the top.

２種類のパネルを重ねるには、図７（ａ）、（ｂ）、（ｃ）のように上から順に太陽光発電パネル１、太陽光集光パネル５を重ねる場合、上から順に太陽光発電パネル１、太陽熱吸収パネル３を重ねる場合、上から順に太陽熱吸収パネル３、太陽光集光パネル５を重ねる場合がある。   In order to stack two types of panels, when the photovoltaic power generation panel 1 and the solar light collecting panel 5 are stacked in order from the top as shown in FIGS. When the panel 1 and the solar heat absorption panel 3 are stacked, the solar heat absorption panel 3 and the solar light collecting panel 5 may be stacked in order from the top.

また、１つのパネル設置部１３にパネルを１枚単独で単層として設置する例としては、図３、図４、図５に示すに示す太陽光発電パネル１、太陽熱吸収パネル３、太陽光集光パネル５のうちいずれか１種類を選択して設置する。   Moreover, as an example which installs one panel as a single layer in one panel installation part 13, as shown in FIG.3, FIG.4, FIG.5, the solar power generation panel 1, the solar heat absorption panel 3, and a solar collector shown in FIG. One of the light panels 5 is selected and installed.

図１、図２には複数のパネル設置部１３に、それぞれ、上から順に太陽光発電パネル１、太陽熱吸収パネル３、太陽光集光パネル５を３枚重ねて設置した例を示している。   FIG. 1 and FIG. 2 show examples in which a plurality of photovoltaic power generation panels 1, a solar heat absorption panel 3, and a solar light collecting panel 5 are installed on a plurality of panel installation parts 13 in order from the top.

設置に当たっては、最下段の太陽光集光パネル５を載置用突部１４に載置し、太陽熱吸収パネル３、太陽光発電パネル１の順に重ね、設置枠１２に設けた固定手段１５で固定する。図１の実施形態では、固定手段１５が、設置枠１２から上方に突出したネジ棒１５ａと、ネジ棒１５ａに挿入した押さえ板１５ｂと、ネジ棒１５ａに螺合したナット１５ｃで構成してある。もちろん、固定手段１５としては上記例にのみ限定されず、種々設計変更可能である。   For installation, the lowermost solar light collecting panel 5 is placed on the mounting projection 14, the solar heat absorbing panel 3 and the solar power generation panel 1 are stacked in this order, and fixed by fixing means 15 provided on the installation frame 12. To do. In the embodiment of FIG. 1, the fixing means 15 includes a screw rod 15a protruding upward from the installation frame 12, a holding plate 15b inserted into the screw rod 15a, and a nut 15c screwed into the screw rod 15a. . Of course, the fixing means 15 is not limited to the above example, and various design changes can be made.

本実施形態において、太陽光はまず上の太陽光発電パネル１の全面で受光され、パネル本体１ａの発電部で太陽光を電気エネルギーに変換して発電する。なお、太陽光発電パネル１として色素増感型の太陽光発電パネル１を用いると、太陽光発電パネル１の色調を発電効率の良い色調のものとすることができる。   In the present embodiment, sunlight is first received by the entire surface of the upper photovoltaic power generation panel 1, and is generated by converting the sunlight into electric energy by the power generation unit of the panel body 1 a. In addition, when the dye-sensitized solar power generation panel 1 is used as the solar power generation panel 1, the color tone of the solar power generation panel 1 can be set to a color tone with good power generation efficiency.

パネル本体１ａは光透過性を有しているので、電気エネルギーに変換されなかった太陽光は、パネル本体１ａを透過して中間に位置する太陽熱吸収パネル３の全面で受光される。   Since the panel main body 1a is light transmissive, sunlight that has not been converted into electric energy passes through the panel main body 1a and is received by the entire surface of the solar heat absorption panel 3 located in the middle.

この太陽熱吸収パネル３では受光された太陽光を熱エネルギーに変換して熱媒流路２内の熱媒を加熱する。この太陽熱吸収パネル３には下面に断熱材９を設けてあるので、熱が太陽熱吸収パネル３から下の太陽光集光パネル５側に逃げるのを抑制し、太陽熱吸収パネル３における熱エネルギーへの変換効率が向上する。   The solar heat absorption panel 3 converts the received sunlight into heat energy and heats the heat medium in the heat medium flow path 2. Since this solar heat absorption panel 3 is provided with the heat insulating material 9 on the lower surface, it is possible to suppress heat from escaping from the solar heat absorption panel 3 to the lower solar light collecting panel 5 side, and to the heat energy in the solar heat absorption panel 3. Conversion efficiency is improved.

また、上記のように、太陽光発電パネル１直下で、太陽熱吸収パネル３において吸熱して熱媒流路２内の熱媒を加熱するので、太陽光発電パネル１から太陽熱吸収パネル３が熱を奪うことになり、太陽熱吸収パネル３を冷却して太陽光発電パネル１における発電効率が低下しない。   Further, as described above, the solar heat absorption panel 3 directly absorbs heat and heats the heat medium in the heat medium flow path 2 so that the solar heat absorption panel 3 generates heat from the solar power generation panel 1. Therefore, the solar heat absorption panel 3 is cooled and the power generation efficiency in the solar power generation panel 1 does not decrease.

なお、太陽熱吸収パネル３の熱媒流路２が太陽光発電パネル１の下面に接触するように形成すると、太陽光発電パネル１から直接熱媒流路２に吸熱でき、太陽光発電パネル１を冷却して発電効率が向上すると共に太陽熱吸収パネル３における熱エネルギーへの変換効率が向上する。   In addition, if it forms so that the heat-medium flow path 2 of the solar heat absorption panel 3 may contact the lower surface of the solar power generation panel 1, it can absorb heat directly from the solar power generation panel 1 to the heat-medium flow path 2, and the solar power generation panel 1 is attached. The power generation efficiency is improved by cooling, and the conversion efficiency to thermal energy in the solar heat absorption panel 3 is improved.

なお、太陽光発電パネル１としてアモルファス型の太陽光発電パネル１を用いると、アモルファス型の太陽光発電パネル１は熱が蓄熱される傾向にあるので、アモルファス型の太陽光発電パネル１に蓄熱された熱を太陽熱吸収パネル３で吸収して熱吸収効率を向上できる。   In addition, when the amorphous solar power generation panel 1 is used as the solar power generation panel 1, the amorphous solar power generation panel 1 is stored in the amorphous solar power generation panel 1 because heat tends to be stored. The heat absorption efficiency can be improved by absorbing the generated heat by the solar heat absorption panel 3.

太陽熱吸収パネル３を透過した太陽光は、下に位置する太陽光集光パネル５の集光部４で集光され、集光された光は導光路６から外部に取り出され、太陽光集光パネル５から離れた箇所において照明として利用される。   Sunlight that has passed through the solar heat absorption panel 3 is collected by the light collecting section 4 of the sunlight collecting panel 5 located below, and the collected light is taken out from the light guide path 6 to collect sunlight. It is used as illumination at a location away from the panel 5.

このように複数のパネル設置部１３に、それぞれ、太陽光発電パネル１、太陽熱吸収パネル３、太陽光集光パネル５を３枚重ねて設置すると、狭い設置面積で、太陽光を電気エネルギー、熱エネルギー、光として効率的に利用することができる。   In this way, when the photovoltaic power generation panel 1, the solar heat absorption panel 3, and the solar light collecting panel 5 are installed on the plurality of panel installation sections 13, respectively, sunlight is converted into electric energy and heat with a small installation area. It can be used efficiently as energy and light.

図８、図９に示す実施形態は、設置枠１２の複数のパネル設置部１３のうち、１乃至複数のパネル設置部１３に３種類のパネルを重ねて設置し、残りの１乃至複数のパネル設置部１３に３種類のパネルのうち任意の種類のパネルを単独で一層（１枚）のみ設置した例である。   In the embodiment shown in FIGS. 8 and 9, among the plurality of panel installation portions 13 of the installation frame 12, three types of panels are installed on one or more panel installation portions 13, and the remaining one or more panels are installed. This is an example in which only one layer (one sheet) of arbitrary types of panels among the three types of panels is installed on the installation unit 13.

上記残りの設置部１３に単独で一層のみ設置するパネルとしては、上記３種類のパネルすべてをそれぞれ単独で一層のみで設置する場合、いずれか２種類のパネルをそれぞれ単独で一層のみで設置する場合、いずれか１種類のパネルのみを単独で一層のみで設置する場合がある。   As a panel to be installed in the remaining installation section 13 alone in a single layer, when all the above three types of panels are installed in a single layer alone, any two types of panels are installed in a single layer alone In some cases, only one type of panel is installed alone in only one layer.

これにより、本発明においては、太陽光から電気エネルギー、熱エネルギー、光を得るものにおいて、目的に応じて電気エネルギー、熱エネルギー、光のうちいずれかを重点的に多く得ることができる。   Thereby, in this invention, in what obtains electrical energy, thermal energy, and light from sunlight, according to the objective, any one of electrical energy, thermal energy, and light can be obtained intensively.

また、図１０、図１１に示す実施形態は、複数のパネル設置部１３のうち任意のパネル設置部１３に上記３種類のパネルを重ねて設置し、他の複数のパネル設置部１３に、３種類のパネルのうち異なる２種類のパネルを重ねて設置した例である。なお、上記例で残りのパネル設置部１３に２種類のパネルを重ねる場合、図１０の例の例に限定されず、目的に応じて、太陽光発電パネル１と太陽熱吸収パネル３を重ねたり、太陽熱吸収パネル１と太陽光集光パネル３を重ねてもよい。   In the embodiment shown in FIGS. 10 and 11, the above-described three types of panels are stacked on an arbitrary panel installation unit 13 among the plurality of panel installation units 13, and 3 This is an example in which two different types of panels among the types of panels are stacked. In addition, when stacking two types of panels on the remaining panel installation portion 13 in the above example, the panel is not limited to the example of FIG. 10, and depending on the purpose, the photovoltaic power generation panel 1 and the solar heat absorption panel 3 may be stacked, The solar heat absorption panel 1 and the solar light collecting panel 3 may be stacked.

また、設置枠１２に設けた複数のパネル設置部１３のうち、１乃至複数のパネル設置部１３に３種類のパネルを重ねて設置し、別のパネル設置部１３に任意の２種類のパネルを重ねて設置し、更に、残りのパネル設置部１３に任意の１種類のパネルを１枚設置してもよい。   In addition, among the plurality of panel installation units 13 provided in the installation frame 12, three types of panels are stacked on one or more panel installation units 13, and any two types of panels are installed on another panel installation unit 13. In addition, one arbitrary type of panel may be installed in the remaining panel installation unit 13.

更に、設置枠１２に設けた複数のパネル設置部１３のうち、１乃至複数のパネル設置部１３に任意の２種類のパネルを重ねて設置し、残りの１乃至複数のパネル設置部１３に３種類のパネルのうち任意の種類のパネルを１枚設置してもよい。   Further, among the plurality of panel installation sections 13 provided in the installation frame 12, any two types of panels are stacked and installed on one to a plurality of panel installation sections 13, and the remaining one to a plurality of panel installation sections 13 have 3 One type of panel may be installed among the types of panels.

更に、設置枠１２に設けた複数のパネル設置部１３の全てにそれぞれ任意の２種類のパネルを重ねて設置してもよい。この場合、図７（ａ）（ｂ）（ｃ）に示す２種類のパネルの組合せ例のうち、（ａ）と（ｂ）を並設したり、（ｂ）と（ｃ）を並設したり、（ａ）と（ｃ）を並設したり、（ａ）と（ｂ）と（ｃ）を並設したりする。これにより設置枠１２に３種類のパネルが必ず設置される。   Furthermore, any two types of panels may be stacked on each of the plurality of panel installation portions 13 provided in the installation frame 12. In this case, among the combinations of the two types of panels shown in FIGS. 7A, 7B, and 7C, (a) and (b) are juxtaposed, or (b) and (c) are juxtaposed. Or (a) and (c) are juxtaposed, or (a), (b) and (c) are juxtaposed. As a result, three types of panels are always installed in the installation frame 12.

上記各実施形態は、３種類のパネルを使用するだけでなく、少なくとも複数のパネル設置部１３のいずれかに２種類又は３種類のパネルを重ねて設置するので、狭い設置面積で、太陽光から電気エネルギー、熱エネルギー、光を得ることができる。   In each of the above embodiments, not only three types of panels are used, but also two or three types of panels are stacked and installed on at least one of the plurality of panel installation portions 13, so that it is possible to reduce sunlight from a small installation area. Electric energy, heat energy and light can be obtained.

なお、本発明に用いる太陽光集光パネル５に、図１２の制御ブロック図に示すような、色調が調整可能な発光手段７と、色調センサ１１を設けてもよい。本例の太陽光集光パネル５を用いる場合、太陽光集光パネル５に受光する光を色調センサ１１で検知し、検知結果に基づき、制御手段８で発光手段７で発光する光の色調を調整し、導光路６から外部に取り出す光の色調を目的とする色調にする。上記色調を調整可能な発光手段７としては例えば色温度可変ＬＥＤを用い、発光手段７は太陽光発電パネル１で発電した電力又は電力会社からの電力を用いて発光する。   In addition, you may provide the light emission means 7 and the color tone sensor 11 which can adjust color tone as shown in the control block diagram of FIG. 12 in the sunlight condensing panel 5 used for this invention. When the solar light collecting panel 5 of this example is used, the light received by the solar light collecting panel 5 is detected by the color sensor 11, and the color tone of the light emitted by the light emitting means 7 is controlled by the control means 8 based on the detection result. The target color tone is adjusted by adjusting the color tone of the light extracted from the light guide path 6 to the outside. As the light emitting means 7 capable of adjusting the color tone, for example, a color temperature variable LED is used, and the light emitting means 7 emits light using electric power generated by the photovoltaic power generation panel 1 or electric power from an electric power company.

上記のように、色調が調整可能な発光手段７を設けて光を合成することで、太陽光集光パネル５を単独で一層のみで設置する場合は、集光する光が利用目的と異なる色調であっても、導光路６から外部に取り出す光の色調を目的の色調に調整して取り出すことができる。   As described above, by providing the light emitting means 7 capable of adjusting the color tone and synthesizing the light, when the solar light collecting panel 5 is installed alone with only one layer, the condensed light has a color tone different from the purpose of use. Even so, the color tone of the light extracted from the light guide 6 to the outside can be adjusted to the target color tone and extracted.

これにより、例えば、集光する光の色調が夕方変化して昼間の自然光と異なる色調となっても、発光手段７で発光する光と合成して、昼間の自然光と同じ色調の光を導光路６から外部に取り出すことができる。   Thereby, for example, even if the color tone of the condensed light changes in the evening and becomes a color tone different from that of natural light in the daytime, the light having the same color tone as that of the natural light in the daytime is combined with the light emitted by the light emitting means 7. 6 can be taken out to the outside.

また、太陽光集光パネル５の上方に少なくとも太陽光発電パネル１を重ねて設置する場合は、太陽光発電パネル１を透過した光が利用目的と異なる色調の光であっても、導光路６から外部に取り出す光の色調を目的とする色調に調整して利用目的に応じた光の有効利用ができる。   Further, in the case where at least the solar power generation panel 1 is installed above the solar light collecting panel 5, even if the light transmitted through the solar power generation panel 1 is light having a color tone different from the purpose of use, the light guide 6 By adjusting the color tone of the light extracted from the outside to the target color tone, it is possible to effectively use the light according to the purpose of use.

なお、光透過性の太陽光発電パネル１の下方に少なくとも太陽光集光パネル５を重ねて設置する場合、光透過性の太陽光発電パネル１をグレー系の色とすることも好ましい。昼間の自然光は、グレー系の光透過性の太陽光発電パネル１を透過してもその色調が変化せず、太陽光集光パネル５で集光され、導光路６から外部に取り出す光として昼間の自然光の色調を維持できる。したがって、この例の場合は、発光手段７を設けなくてもよい。   In addition, when installing at least the sunlight condensing panel 5 on the lower side of the light-transmitting photovoltaic power generation panel 1, it is also preferable that the light-transmitting photovoltaic power generation panel 1 has a gray color. Daytime natural light does not change its color tone even if it passes through the gray light-transmitting photovoltaic power generation panel 1, is condensed by the sunlight collecting panel 5, and is extracted as daylight as light extracted from the light guide path 6. The natural light color tone can be maintained. Therefore, in this example, the light emitting means 7 may not be provided.

なお、太陽熱吸収パネル３に設ける熱媒流路２内に流す熱媒としては液体にのみ限定されず、気体であってもよい。   In addition, as a heat medium sent in the heat medium flow path 2 provided in the solar heat absorption panel 3, it is not limited only to a liquid, A gas may be sufficient.
