Description

本発明は、太陽電池パネルの設置構造に関し、詳しくは広い受光面を有する建築物の外周壁又は屋外壁の最外面壁に対して、隣地境界線の範囲内で、かつ該壁面に直接でなく躯体に設置金具を接合し空隙間隔を設け、太陽電池パネルの少なくとも複数組を外壁面から直角に突き出るように設置叉は袖壁状に鉛直設置し、屋上に加えて発電面積の拡大を図り、同時に建築物の意匠性を向上せしめると共に、環境景観への配慮を図った太陽電池パネルの設置構造に関する。The present invention relates to an installation structure of a solar cell panel, and more particularly, to an outer peripheral wall of a building having a wide light receiving surface or an outermost wall of an outdoor wall, within the range of an adjacent boundary line and not directly to the wall surface. Install installation brackets to the housing to provide gap spacing, install at least multiple sets of solar cell panels vertically so as to protrude perpendicularly from the outer wall surface or sleeve wall shape, and expand the power generation area in addition to the rooftop, At the same time, it relates to the installation structure of the solar cell panel that improves the design of the building and considers the environmental landscape.

近年、太陽光発電は地球環境保全の立場からも排気ガス、放射線等の公害を発生することのないクリーンなエネルギー源として注目され、多種多様の太陽電池が開発され、かつ量産化による価格低減も進んで、幅広い用途開発がなされ、政府の住宅に関する環境政策も相俟ってビル等の建造物にも多用されるようになってきた。このように太陽光発電の普及や促進が図られるのに伴って、その外観も重要な位置付けとなってきており、ビル壁面や屋上等の広い受光面を有する建築物に太陽光発電システムを設置するとき、発電以外にも景観環境への関心が高まりつつある。In recent years, solar power generation has attracted attention as a clean energy source that does not generate pollution such as exhaust gas and radiation from the standpoint of global environmental conservation, and a wide variety of solar cells have been developed, and the price can be reduced by mass production. A wide range of uses have been developed, and the government's environmental policy on housing has been used in many buildings. As solar power generation is promoted and promoted in this way, its appearance has also become important, and solar power generation systems are installed on buildings with wide light receiving surfaces such as building walls and rooftops. In addition to power generation, there is a growing interest in the landscape environment.

ビル等の建築物の屋上や住宅の屋根は、空きスペースで、かつ日当たりの最も良い部位であることから設置場所は専らここに集中している。ところが、ビルの屋上にはエレベーターの機械室や階段室、場合によっては空調の室外機等の設置場所が必要であり、また、最近ではヒートアイランド現象の防止或いは自然環境と共生する意識の高揚から屋上庭園やビオトープ、菜園等を設けるビルも多く利用面積に限りがある。できる限り広範囲を占有したくとも太陽電池パネルの設置場所は自ずと限定されてしまうのが通例である。Since the rooftops of buildings such as buildings and the roofs of houses are empty spaces and are the best parts of sunlight, the installation locations are concentrated here. However, there is a need for an elevator machine room and staircase on the rooftop of the building, and in some cases, an air conditioner outdoor unit, etc. Recently, the rooftop is used to prevent the heat island phenomenon or raise awareness of coexistence with the natural environment. Many buildings have gardens, biotopes, vegetable gardens, etc., and their usage area is limited. Even if you want to occupy as wide a range as possible, the installation location of solar panels is usually limited.

上記の問題点を解決する為、設置面積の拡大を図る手段として、例えば下記のような提案がなされている。特開２００２−０７６４１５号公報や特開平０８−１６２６６０号公報には、太陽電池モジュールを１本のポールに多段にわたって取り付けることにより空きスペースを有効に使えると提案されているが、短冊状の複数のモジュールが、風圧を受けて揺れ、安定性に疑問がある。また、特開平０６−３１８７２６号公報、及び特開平０６−２４４４４５号公報には、屋根のみならず外壁への設置も提案されている。しかしながら、これらの発明は効率的な受光手段のみに注意が払われており、建築物の意匠性、周開の環境等に関しては余り配慮がなされていない。In order to solve the above problems, for example, the following proposals have been made as means for increasing the installation area. Japanese Patent Application Laid-Open No. 2002-076415 and Japanese Patent Application Laid-Open No. 08-162660 propose that the empty space can be used effectively by attaching the solar cell module to one pole in multiple stages. The module sways under the wind pressure, and its stability is questionable. JP-A 06-318726 and JP-A 06-244445 also propose installation on the outer wall as well as the roof. However, in these inventions, attention is paid only to the efficient light receiving means, and not much consideration is given to the design of the building, the environment of the surroundings, and the like.

特許文献１（特開２００８−１１１３２２号公報）には、壁面に取り付ける建築用化粧板であって、その表面に可視光透過率が、２０％以上の色素増感型太陽電池を設けておくことにより、太陽電池を透して化粧板の文樣が視認できると提案されている。太陽電池パネル自体のデザイン性を追求した発明ではあるが、壁面に対する取り付けが平面状であることから、設置面積を大きく稼ぐことにはなっていない。Patent Document 1 (Japanese Patent Application Laid-Open No. 2008-111322) discloses a decorative decorative plate to be attached to a wall surface, on which a dye-sensitized solar cell having a visible light transmittance of 20% or more is provided. Therefore, it is proposed that the text on the decorative plate can be seen through the solar cell. Although it is an invention pursuing the design of the solar cell panel itself, the installation to the wall surface is flat, so that the installation area is not greatly earned. 特許文献２（特開平１０−０１８４６７号公報）には、設置景観を損なわない遮音材と太陽電池の一体化パネルが提案されている。高速道路の防音壁の外側に太陽電池が臨むよう設置されている巨大な建築物の外観は、黒っぽい色調を有する異様な光景といわざるを得ず、意匠性は皆無である。Patent Document 2 (Japanese Patent Laid-Open No. 10-018467) proposes an integrated panel of a sound insulating material and a solar cell that does not impair the installation landscape. The appearance of a huge building with solar cells facing the outside of the noise barrier on the highway is inevitably a strange sight with a blackish tone, and has no design. 特許文献３（特開平０９−０２１１１７号公報）には、高速道路の遮音壁と一体化した太陽電池パネルから得られた電力でトンネル内に設けた絵柄を映し出しドライバーの単調さを癒すと提案されているが、受光面がデザイン性に乏しいことに変わりはない。Patent Document 3 (Japanese Patent Application Laid-Open No. 09-021117) proposes to heal the monotonousness of the driver by projecting the picture provided in the tunnel with the electric power obtained from the solar cell panel integrated with the sound insulation wall of the highway. However, the light receiving surface is still poor in design. 特許文献４（特開平２００２−０１０４９４号公報）には、高速道路の橋桁や柵、側壁、コンクリート柱等に取り付けることが提案されている。膨大なスペースの有効利用という発想は優れているものの、側壁に対しては平面状に取り付けられており、前述のように建造物としての意匠性は低い。Patent Document 4 (Japanese Patent Application Laid-Open No. 2002-010494) proposes attachment to a bridge girder, a fence, a side wall, a concrete pillar, or the like of an expressway. Although the idea of effective use of a vast space is excellent, it is attached to the side wall in a flat shape, and the design as a building is low as described above. 特許文献５（特開平２００５−２２３１６４号公報）には、両面受光太陽電池が記載されており、太陽の方向に合わせて壁面に垂直に設置すれば効率よく発電が可能であると提案されている。しかしながら、特許文献５の両面受光型太陽電池の裏面側、即ち透明バックシート側の發電効率は特に薄膜シリコン型太陽電池を使った場合、表面側のそれに比べて劣るであろうから、単結晶か多結晶シリコン型を用いざるを得ず、これらは黒っぽく不透明であることから室内を暗くし鬱陶しい感じが拭えない。また、単結晶か多結晶シリコン型は薄膜シリコン型と比べて高価で数多くのパネルを並列させると極めて不経済である。更に、特許文献５の両面受光型太陽電池で設置角度を６０度とした時、片面受光型に比べて１２０度の電力量が得られると記載されており、表面のみで發電する片面受光型に比べて裏面にも發電機能を備えたシステムは年間発電量が大きくなるのは当然である。また、垂直設置方法において、建築物の屋上、主としてその周囲にフェンス一体形、または手摺一体形として地表面に対して垂直することを特徴としており、複数の該パネルは、平面状に配列されているだけで建築物の壁面から垂直に突き出るよう設置することにはなっておらず、設置面積の有効利用を鑑みると不十分である。高速道路の側壁や橋脚等の部位への設置においても同様で、平面状受光に変わりない。Patent Document 5 (Japanese Patent Application Laid-Open No. 2005-223164) describes a double-sided light receiving solar cell, which is proposed to be capable of efficient power generation if it is installed vertically on a wall surface in accordance with the sun direction. . However, the backside of the double-sided solar cell of Patent Document 5, that is, the transparent efficiency on the transparent backsheet side will be inferior to that on the front side, particularly when using a thin-film silicon solar cell. There is no choice but to use polycrystalline silicon molds, and these are dark and opaque, making the room darker and irritating. Also, the single crystal or polycrystalline silicon type is more expensive than the thin film silicon type, and it is extremely uneconomical when many panels are arranged in parallel. Furthermore, it is described that when the installation angle is set to 60 degrees in the double-sided light receiving solar cell of Patent Document 5, an electric energy of 120 degrees can be obtained compared to the single-sided light receiving type, In comparison, it is natural that a system with a backside power function on the back side will increase the annual power generation. Further, in the vertical installation method, the building is characterized in that it is perpendicular to the ground surface as a fence-integrated or handrail-integrated shape mainly on the roof of the building, and the plurality of panels are arranged in a planar shape. It is not installed so as to protrude vertically from the wall surface of the building, and it is insufficient in view of effective use of the installation area. The same applies to the installation on the side walls, piers, etc. of the expressway, and there is no change to planar light reception. 特許文献６（ＷＯ２００５／０７４０３９）には、太陽電池素子を複数個接続し配置した太陽電池モジュールを用いた太陽光発電装置が記載されているが、本願発明とは、両面受光型発電装置の構造で相違している。本願発明では、２枚のパネルを合わせて１枚の両面受光パネルに組み立てた構成である。すなわち裏面被覆材の合わせ目を境として、上下それぞれで片面受光のパネルになっているものを、背中合わせにしてフレームで固定した構成である。一方、特許文献６では、片面受光の太陽電池素子群を中間部材を挟んで、充填材（ＥＶＡ）で上下を一体として組み立てた構成である。すなわち両面受光パネルとして１枚のパネルに形成した構成である。また、特許文献６では、両面受光型太陽電池モジュールを建築物の外壁面から直角に突き出るように設置することはもとより該外壁面に袖壁状に鉛直設置すること、さらには外壁面等への取り付け構造について何ら記載も示唆もない。さらに、特許文献６では充填材で上下一体成形の簡易な両面型の構造としているが、補修交換でも一体成形の制約を免れない。一方、本願発明の両面受光型パネルでは両側のフレームを取り外し片面毎の交換修復が可能であり、また、フレームを取り外せば２枚に分かれ、新たに適切な寸法（厚さ）のフレームを取り付けると、通常の片面受光型パネルとなり両者は構成において相違する。Patent Document 6 (WO2005 / 074039) describes a solar power generation device using a solar cell module in which a plurality of solar cell elements are connected and arranged. The invention of the present application is a structure of a double-sided light receiving power generation device. Is different. In the present invention, the two panels are combined into a single double-sided light receiving panel. That is, it is a configuration in which the single-sided light receiving panels on the upper and lower sides are fixed back-to-back with a frame at the joint of the back surface covering material. On the other hand, in patent document 6, it is the structure which assembled the solar cell element group of the single-sided light reception on the upper and lower sides integrally with the filler (EVA) on both sides of the intermediate member. That is, the double-sided light receiving panel is formed as a single panel. Further, in Patent Document 6, the double-sided light-receiving solar cell module is not only installed so as to protrude perpendicularly from the outer wall surface of the building, but is also installed vertically on the outer wall surface in the form of a sleeve wall, and further to the outer wall surface, etc. There is no description or suggestion about the mounting structure. Furthermore, in Patent Document 6, a simple double-sided structure is integrally formed with the filler using the upper and lower integral molding, but the restriction of integral molding is unavoidable even with repair replacement. On the other hand, in the double-sided light receiving panel of the present invention, the frame on both sides can be removed and repaired for each side, and if the frame is removed, it can be divided into two pieces and a new frame of appropriate size (thickness) is attached. The conventional single-sided light receiving panel is different in configuration. 特開２００３−１６６２２０公報には、防護柵の道路の反対側に両面型太陽電池パネルが突設されている屋外工作物が開示されている。すなわち両面型太陽電池パネルを取り付けた屋外工作物の概念図が記載されており、両面型太陽電池パネルを備えた防護柵からなる屋外工作物は、その防護柵の柵体が両面型太陽電池パネルであることを特徴としている。しかし両面型太陽電池パネルを備えた防護柵を図示しているが、具体的にどのように設置するのか、その設置方法並びに設置構造として取り付け方法についても何ら記載がない。また、本願での建築物の外壁に設置と、特許文献７の道路防護柵に一体型の設置では設置対象の格差は顕著であり、まず特許文献７では、公共道路の反対側に防護柵一体型の太陽電池パネルが突設されているが、民間での隣地境界線の制約の如きが考慮されているとはいい難い。さらに本願では、建築物の外壁面へ直角に突き出るように設置叉は袖壁状に鉛直設置のいずれの場合も、壁面温度上昇の阻害要因を抑制の為、建築物の外壁面に直接に装着せず、躯体に設置金具を接合して壁面に固定し間隙空間を設けた構成であり、特許文献７と設置構造でも差異は顕著である。Japanese Patent Application Laid-Open No. 2003-166220 discloses an outdoor workpiece in which a double-sided solar panel protrudes from the opposite side of a protective fence road. In other words, a conceptual diagram of an outdoor workpiece with a double-sided solar panel is described, and an outdoor workpiece consisting of a protective fence equipped with a double-sided solar panel is a double-sided solar panel. It is characterized by being. However, although the protective fence provided with the double-sided solar cell panel is illustrated, there is no description about how to install it specifically, its installation method, and installation method as an installation structure. Moreover, the disparity of the installation object is conspicuous in the installation on the outer wall of the building in this application and the installation in the road protection fence of Patent Document 7, and first, in Patent Document 7, there is a protection fence on the opposite side of the public road. The body-shaped solar panel protrudes, but it is difficult to say that the restrictions on the boundary line of the adjacent land in the private sector are taken into consideration. Furthermore, in this application, in either case of vertical installation to the outer wall of the building or vertical installation to the sleeve wall, it is directly attached to the outer wall of the building in order to suppress the hindrance to wall temperature rise. Instead, the installation metal fitting is joined to the housing and fixed to the wall surface to provide a gap space, and the difference is significant between Patent Document 7 and the installation structure.

発明が解決しようとする課題Problems to be solved by the invention

本発明は、建築物のデザイン性を損ねることなく、外壁面の未利用部位を有効に使って設置でき、屋根部の発電を補助することが可能な太陽光パネルの設置構造の提供を目的としている。It is an object of the present invention to provide a solar panel installation structure that can be installed by effectively using unused parts of the outer wall without damaging the design of the building, and that can assist in power generation on the roof. Yes.

課題を解決するための手段Means for solving the problem

本発明では、建築物の外壁面から直角に突き出るよう立体的に設置する構造に関し、詳しくは、２枚の片面受光太陽電池パネルを背中合わせにして両面受光型に加工し、袖壁状に鉛直設置することに想到し、本発明を完成するに至った。The present invention relates to a structure that is three-dimensionally installed so as to protrude perpendicularly from the outer wall surface of a building. Specifically, two single-sided light receiving solar cell panels are processed back-to-back and installed vertically in a sleeve wall shape. The present invention has been completed.

本発明による太陽電池パネルは、出願人が提案の先行特許第３２８６５７７号公報、特許第３４８２３７０号公報及び特許第３０４９２３８号公報に記載の、カバーガラスの表面にセラミック・インキを用いて、スクリーン印刷法により凸状膨隆部が形成された透光性基板の太陽電池モジュールを使用することもできる。The solar cell panel according to the present invention is obtained by a screen printing method using ceramic ink on the surface of a cover glass described in the prior patents Nos. 3286777, 3482370 and 3049238 proposed by the applicant. Thus, a solar cell module of a translucent substrate in which a convex bulge is formed can also be used .

本願発明では、特許文献５に記載の両面受光型太陽電池、単結晶シリコン型、多結晶シリコン型或いは薄膜シリコン型等の太陽電池も用いることもできる。その中でも安価な薄膜シリコン型はモジュールの大きさを自由に変えられるという利点から好適である。 In the present invention, a double-sided light-receiving solar cell described in Patent Document 5, a single crystal silicon type, a polycrystalline silicon type, or a thin film silicon type solar cell can also be used. Among these, an inexpensive thin-film silicon mold is preferable because of the advantage that the module size can be freely changed.

袖壁状鉛直設置構造にあっては、開口部を有しない側壁全面に複数個設置しても良いし、開口部と開口部の間に設置しても良く、開口部の大きさや、その位置と太陽光パネルの設置場所をバランス良く設置することにより、豊かな表情を持った建築物を創出することができる。室内側からは外部風景の視認が可能で、また、庇のように上部に取り付けられるものではないので採光を妨げることもないし、プライバシー保護の為の目隠し或いはパーテーションとしても機能する。In the case of a sleeve-wall-like vertical installation structure, a plurality of installations may be provided on the entire side wall having no opening, or between the opening and the opening, and the size and position of the opening. And a well-balanced installation location of solar panels can create a building with a rich expression. Outside scenery can be seen from the indoor side, and since it is not attached to the upper part like a kite, it does not interfere with daylighting and functions as a blindfold or partition for privacy protection.

受光面に当たった光は、表面のガラスを透過して太陽電池素子に吸収されるが、朝夕の太陽高度が低い時、即ち入射角が大きい場合は光線が吸収されにくく、低反射ガラスを使用した太陽光パネルであっても完全吸収はあり得ず、屋上に設置された平置きタイプでは反射光は逸散してしまうだけである。これに対して、本発明の複数組の両面受光パネルを鉛直設置することにより隣接するパネルの反射光を貰い受けて発電に供することが可能となり、その結果パネル１組当たりの発電効率は向上する。Light that hits the light-receiving surface passes through the glass on the surface and is absorbed by the solar cell element. However, when the solar altitude is low in the morning and evening, that is, when the incident angle is large, light is not easily absorbed, and low-reflection glass is used. Even if it is a solar panel, there is no perfect absorption, and the flat light installed on the roof only dissipates the reflected light. On the other hand, by vertically installing a plurality of sets of double-sided light receiving panels according to the present invention, it becomes possible to receive reflected light from adjacent panels for power generation, and as a result, the power generation efficiency per set of panels is improved. .

また、壁面では屋上に設置されたものに比べて発電効率が低下するが、設置枚数を多くして補えばよく、これによるスケールメリットを生かして原価の低減を図ることが可能で、更に、夏季における夕暮れ時には西日を遮り室内の気温上昇を抑制できる。In addition, although the power generation efficiency on the wall surface is lower than that on the rooftop, it can be compensated by increasing the number of installations, making it possible to reduce costs by taking advantage of the scale advantage. At dusk, it can block the sun and suppress the temperature rise in the room.

また、本発明のビル外壁等に袖壁状に鉛直設置する構造では、設計士の感性によって、本発明の両面受光型太陽電池と、例えば２枚の片面受光型太陽電池パネルの受光面を外側にして合わせた両面受光型太陽電池を三角出窓状に組み立て設置する三角出窓状太陽電池パネルを組み合わせて配置することにより、建築物のファッション性をより向上させることができる。 In addition , in the structure of the present invention that is installed vertically on the outer wall of the building in the form of a sleeve wall , the double-sided light-receiving solar cell of the present invention and , for example, the light-receiving surfaces of two single-sided light-receiving solar cell panels are arranged outside depending on the sensitivity of the designer. The fashionability of a building can be further improved by combining and arranging triangular bay window solar cell panels that are assembled and installed in a triangular bay window.

一般に、半導体素子は湿度の上昇に伴い素子の性能が低下することが知られており、非結晶光半導体素子太陽電池は、温度上昇１℃当たり変換効率は約０．２５％低下するといわれている。よって、パネルの温度上昇を如何にして低く抑え変換効率の低下を防ぐかは重要課題の一つである。本発明の両面受光型太陽電池パネルでは、ビル外壁面への設置では、該パネル本体は、躯体にボルト、ナット等の設置金具を用い、外壁面に直接でなく取り付け装着されており、その間隙空間の存在は温度上昇を僅かでも抑制するように働く。In general, it is known that the performance of a semiconductor element decreases with increasing humidity, and it is said that the conversion efficiency of a non-crystalline optical semiconductor element solar cell is reduced by about 0.25% per 1 ° C. temperature increase. . Therefore, how to suppress the temperature rise of the panel to be low and prevent the conversion efficiency from being lowered is one of the important issues. In the double-sided light receiving solar panel of the present invention, when installed on the outer wall surface of the building, the panel body is mounted and mounted on the outer wall surface instead of directly using an installation fitting such as a bolt or a nut. The presence of space works to suppress even a slight increase in temperature.

戸建住宅の勾配屋根に取り付けられるタイプや、ビルの屋上に設置される平置きタイプ等は、降雨による汚染物質の影響を受け易く、汚れによる発電効率の低下が問題視されている。例えば特２００９−１６４４３４号公報には、水が滞留しないようフレームの形状を工夫した提案がなされている。また特開平１０−２９００２０公報には、付着した汚染物質を光触媒によって分解する手段が提案されている。本発明によれば、鉛直方向に設置されるので降雨を直接受けることが少ない上、ガラス表面はセラミックス印刷が施されている故、付着した塵埃は容易に洗い流されるので発電効率の低下を防止することができる。The type that is attached to the sloped roof of a detached house, the flat type that is installed on the roof of a building, etc. are easily affected by pollutants due to rainfall, and the reduction in power generation efficiency due to dirt is regarded as a problem. For example, Japanese Patent Application Publication No. 2009-164434 proposes a devised frame shape so that water does not stay. Japanese Patent Application Laid-Open No. 10-290020 proposes means for decomposing adhering contaminants with a photocatalyst. According to the present invention, since it is installed in the vertical direction, it is less likely to receive rainfall directly, and since the glass surface is ceramic-printed, the attached dust is easily washed away, thus preventing a decrease in power generation efficiency. be able to.

設置可能なパネルの大きさは、大きければ大きいほど受光面積は大きくなるが、取り付け強度に限界がある上、内部から外景を望む場合の圧迫感や建築物の外観状況を鑑み、幅、即ち短片方向が３００〜６００ｍｍ、長さ、即ち長手方向が階高に相当する程度、例えば２５００〜３０００ｍが望ましい。また、厚さは、片面受光太陽電池パネルを背中合わせにした両面受光型パネルの場合は１００ｍｍ程度となる。The larger the size of the panel that can be installed, the larger the light receiving area, but there is a limit to the mounting strength, and the width, that is, the short piece, considering the feeling of pressure and the appearance of the building when the outside view is desired from the inside The direction is preferably 300 to 600 mm, and the length, that is, the longitudinal direction corresponds to the floor height, for example, 2500 to 3000 m. In addition, the thickness is about 100 mm in the case of a double-sided light-receiving panel in which single-sided light-receiving solar cell panels are back to back.

新築ビルへの設置は、躯体の横筋に固定されているアンカーボルトに、プレートを介して太陽電池パネルの長辺部に設けたボルト、ナット、ワッシャー等の設置金具を接合して壁面に固定すればよい。For installation in a new building, anchor bolts, nuts, washers, etc. provided on the long side of the solar panel are joined to the anchor bolts fixed to the horizontal bars of the frame and fixed to the wall surface. That's fine.

また、階高毎に外壁周囲の連続型バルコニーが設けられている場合は、設置金具による接合に加えて、太陽電池パネルの下端をバルコニー上に設置すればより安定する。In addition, when a continuous balcony around the outer wall is provided for each floor height, it is more stable if the lower end of the solar cell panel is installed on the balcony in addition to the joining by the installation bracket.

リニューアルによる後付けの場合は、躯体構造物に穴あけの後、ケミカルアンカーを固着し、これに太陽電池パネルの設置金具を固定すればよい。In the case of retrofitting by renewal, a chemical anchor is fixed after drilling in the housing structure, and the installation bracket of the solar cell panel may be fixed thereto.

発明の効果Effect of the invention

本発明に係る太陽電池パネルの設置構造によれば、建築物の外壁に袖壁状に、複数組取り付けることにより、建物一つ当たりの発電量を屋根部のアレイに加えて大幅に増加することができる上、設置する位置を建築士独自の発想によって設計されれば、建物のファッション性を向上させることができる。According to the solar cell panel installation structure of the present invention, by attaching a plurality of sets to the outer wall of the building in the form of a sleeve wall, the amount of power generation per building can be significantly increased in addition to the array of roofs.
