Description

浮筒基座用双面太阳能模块设置结构 技术领域
本发明是关于一种浮筒基座用双面太阳能模块设置结构。特别是一种能发挥双面太阳能模块最佳发电效能的浮筒基座用双面太阳能模块设置结构。
背景技术
太阳能是现代替代能源中最受瞩目者。由于太阳能发电具有不会枯竭、容易与建物结合等优点，再加上近年来半导体科技的长足进展等，都使得太阳能的光电转换效能持续提升，故使得太阳能光电模块逐渐被广泛应用。
随着太阳能发电的进展，近年来为了提高发电效能，便开发出了一种双面(Bifacial)太阳能模块，相较于传统的单面式(monofacial)太阳能模块，此种双面太阳能模块顾名思义是让模块的正反两面都能因受光而产生电能，进而较单面式太阳能模块有更佳的发电效率。然而，此种双面太阳能模块为了使正反两面都能因受光而产生电能，在设置上便需要考虑各项因素，例如太阳能模块面板的倾斜角度、设置高度等，从而便会使此种双面太阳能模块的设置条件相较单面式太阳能模块的情况要受到许多限制而有持续改进的空间。
另外，太阳能模块经常被设置在建物顶部，也有可能被装设在农田、渔产养殖池甚至是湖泊中。在将太阳能模块设置于建物顶部或农田的情况，由于太阳能模块仍是设置在稳固的地基上，故只要简单地在稳固地基上架设支架，便可将太阳能模块设置于该支架上来加以使用，而在将太阳能模块设置于渔产养殖池甚至湖泊等的情况，由于太阳能模块并无法简单地设置在稳固的地基上，故需先要利用浮筒设施置放于渔产养殖池或湖泊处，再将太阳能模块设置于其上来加以使用。在利用浮筒设置太阳能模块的情况中，目前仍是以设置单面式太阳能模块为主。如图4(a)所示，传统利用浮筒的太阳能模块结构是具有：太阳能面板100；支架101；以及浮 筒102；其设置方式是将太阳能面板100的一边侧直接设置于浮筒102上，将该一边侧的对边侧透过支架101来支撑而使太阳能面板100整体呈倾斜设置。另外，也可如图4(b)所示，使浮筒201本身具有倾斜面202的结构，而将太阳能面板200直接设置于该倾斜面202的部分上。
在将双面太阳能面板如图4(a)所示来加以设置的情况，便会有双面太阳能面板的一边侧是直接设置于浮筒上，导致光线难以进入至浮筒102与太阳能面板100之间，而无法让双面太阳能面板背光面的面板受光的问题，如此一来，将会失去双面太阳能模块的背面发电效能优势。另外，在将双面太阳能面板如图4(b)所示来加以设置的情况，由于双面太阳能面板背光面完全贴合于浮筒201的倾斜面202的部分上，因此将会使得双面太阳面板背光面完全失去发电的效能优势。不论上述何种方式来设置双面太阳能面板的情况，均无法让双面太阳能模块有效地发挥其相较于单面式太阳能模块的发电优势，从而，便需要一种能发挥双面太阳能模块最佳发电效能的浮筒基座用双面太阳能模块设置结构。
本发明人有鉴于上述双面太阳能模块在使用上所遇到的种种问题，乃积极着手从事研究开发，以期可提供一种能发挥双面太阳能模块最佳发电效能的浮筒基座用双面太阳能模块设置结构，经由不断的试验及努力，终于研发出本发明。借助本发明的结构，便能使双面太阳能模块发挥最佳发电效能，以符合经济效益。

具体实施方式
以下，便参照说明书附图来说明本发明一优选实施方式的浮筒基座用双面太阳能模块设置结构。图1显示本发明一优选实施方式的浮筒基座用双面太阳能模块设置结构的概略侧视图。
如图1所示，本发明一优选实施方式的浮筒基座用双面太阳能模块设置结构10，其具有：
浮筒本体11，可使用表面具光线反射效果的既有浮筒，或依需要使用特制的订制浮筒；
双面太阳能面板13，是一板状、片状或层状构造物，具有朝向日照方向的向光面131以及背向设置于该向光面的背光面132，且会相对于该浮筒本体11而以具有一倾斜角度θ的方式来加以设置；以及
支撑构件12，是设置在该浮筒本体11与该双面太阳能面板13之间，用以将该双面太阳能面板13支撑在该浮筒本体11上；
其中该浮筒本体11与该双面太阳能面板13之间的最小间距H为8～120公分，该双面太阳能面板13相对于该浮筒本体11的倾斜角度θ为不大于40度。
在该最小间距H低于8公分的情况，便会有难以使光线进入到该浮筒本体11与该双面太阳能面板13之间，而使得光线便难以反射至该背光面132的问题，故会失去双面太阳能模块的背面发电效能的优势。另一方面，在该最小间距H高于120公分的情况，则会有因间距过高而使光线分散，导致反射到该双面太阳能面板13的该背光面132的光线能量降低的问题，同样会使得双面太阳能模块的背面发电效能降低。
在该双面太阳能面板13相对于该浮筒本体11的倾斜角度比40度要大的情况，会有使得该双面太阳能面板13相对于水平面过于倾向于垂直的问题，故会使得太阳光的入射角度过小，甚至让反射后的太阳光线无法入射至该背光面132，进而让双面太阳能面板13整体受旋光性降低，因此同样会有让发电效能变低的问题。
一优选实施方式的浮筒本体11可为实心构造，但不限于此，浮筒本体11也可根据制造原料来改变该浮筒本体11的构造，例如改变为中空构造。
一优选实施方式中，为实心构造的该浮筒本体11的材质是塑料。在该浮筒本体11的材质为塑料的情况，该塑料可使用例如高密度聚乙烯(HDPE)、聚丙烯(PP)、发泡树脂等。
另外，在该浮筒本体11为中空构造的情况，该浮筒本体11的材质可以为塑料或是金属。在该浮筒本体11为中空构造且材质为塑料的情况，该塑料可使用如高密度聚乙烯(HDPE)、聚丙烯(PP)、发泡树脂等。在该浮筒本体11为中空构造且材质为金属的情况，则该金属可为表面经防锈处理后的金属。
为了增加本优选实施方式的双面太阳能面板13的该背光面132的受光量，该浮筒本体11可设置有能使光线均匀反射至该双面太阳能面板13的该背光面132的光线反射效果面14。
该光线反射效果面14可由涂覆或镀覆来加以形成。该光线反射效果面14可为具有高反射性的涂层(例如，亮色漆涂层、亮光漆涂层)、玻璃层或反光金属层来加以构成。
另外，图2(a)是本发明一实施方式的浮筒基座用双面太阳能模块设置结构的光线反射效果面的聚光构造一实例的概略侧视图，图2(b)是本发明一实施方式的浮筒基座用双面太阳能模块设置结构的光线反射效果面的聚光构造另一实例的概略侧视图。为了进一步地增加本优选实施方式的双面太阳能面板13的该背光面132的受光量，便可如图2(a)、(b)所示，也使该光线反射效果面14成为具有能将光线均匀分配至该背光面132特定位置的聚光构造。参照图2(a)，此聚光构造可为一几何构造，图标中显示为三角构造，或是如图2(b)所示，为一连续弧面所构成的类似波浪构造。借助构造，便可让反射后的光线均匀地被分配至该双面太阳能面板13的该背光面132，而使本发明的浮筒基座用双面太阳能模块设置结构10发挥更佳地发电效能。
再度参看图1所示，本优选实施方式的支撑构件12为可上下伸缩的伸缩支架。借助此伸缩支架12的伸缩，便可易于进行本发明的浮筒基座用双面太阳能模块设置结构10的装卸，或是进行该最小间距H与该倾斜角度θ的调整。
为了使本发明的浮筒基座用双面太阳能模块设置结构10能够平稳地浮在水面上，一优选实施方式的双面太阳能面板13垂直投射于水平面上的面积S’会小于浮筒本体11垂直投射于水平面上的面积S。若是该双面太阳能面板13垂直投射于水平面上的面积S’大于该浮筒本体11垂直投射于水平面 上的面积S的话，便会有容易使该浮筒基座用双面太阳能模块设置结构10倾倒翻覆的问题。
〔发电效能评比〕
接下来，列举几种实施方式，来说明本发明的浮筒基座用双面太阳能模块设置结构10的发电效能。图3(a)是本发明的浮筒基座用双面太阳能模块设置结构在将倾斜角度固定在12度时，改变最小间距所取得的发电效能图。图3(b)是本发明的浮筒基座用双面太阳能模块设置结构在将最小间距固定在45公分时，改变倾斜角度所取得的发电效能图。
图3(a)的横轴是太阳能面板相对于浮筒本体的最小间距H(单位：公分)，纵轴是使用双面太阳能面板的情况相对于使用单面式太阳能面板的情况的发电效能百分比。图3(b)的横轴是太阳能面板相对于浮筒本体的倾斜角度θ(单位：度)，纵轴是使用双面太阳能面板的情况相对于使用单面式太阳能面板的情况的发电效能百分比。
如图3(a)所示，该倾斜角度θ固定为12度时，在该最小间距H为0公分的情况下，双面太阳能面板的发电效能相对于单面式太阳能面板的发电效能的百分比为100.8％，而可以说是几乎没有发电效能上的差异。这是因为在该最小间距H为0公分的情况下，光线会无法进入到该浮筒本体11与该双面太阳能面板13之间，使得该背光面132无法充分地受光，导致该双面太阳能面板13无法发挥背面发电效能的优势。该倾斜角度θ固定为12度时，在该最小间距H为8、15、45、75公分的情况下，该双面太阳能面板13的发电效能相对于单面式太阳能面板的发电效能的百分比分别为110.0％、118.2％、119.3％、118.0％，而呈现出较单面式太阳能面板要为良好的发电效能。倾斜角度θ固定为12度时，在该最小间距H为120公分的情况下，该双面太阳能面板13的发电效能相对于单面式太阳能面板的发电效能的百分比为110.0％，仍可观察到该双面太阳能面板13的发电效能会较单面式太阳能面板要佳，虽其发电效能已低于该最小间距H为75公分时的118.0％，而有开始呈现下降的趋势，但仍为有效的实施方式。推测这是因为在该最小间距H超过120公分的情况，便有因间距过高而使光线分散，导致反射到该双面太阳能面板13的该背光面132的光线能量降低之故。由上述，便可得知 该最小间距H为8～120公分的范围时，便可使该双面太阳能面板13发挥优良的效能。
进一步地，再参照图3(b)，将该最小间距固定在45公分并改变该倾斜角度θ，来进一步地探讨本发明在改变太阳能面板相对于浮筒本体的倾斜角度时的发电效能。
如图3(b)所示，在该最小间距H为45公分，该倾斜角度θ为0、12、22、32度的情况下，该双面太阳能面板13的发电效能相对于单面式太阳能面板的发电效能的百分比分别为119.1％、119.3％、118.3％、117.1％，而呈现出较单面式太阳能面板要良好的发电效能在该最小间距H为45公分。该倾斜角度θ为40度的情况下，该双面太阳能面板13的发电效能相对于单面式太阳能面板的发电效能的百分比分别为110.0％，仍可观察到该双面太阳能面板13的发电效能会较单面式太阳能面板要佳，虽其发电效能已低于该倾斜角度θ为32度时的117.1％，而有开始呈现下降的趋势，但仍为有效的实施方式。最小间距H为45公分时，在倾斜角度θ为42度的情况下，该双面太阳能面板13的发电效能相对于单面式太阳能面板的发电效能的百分比为106.0％，而有大幅下降的趋势。这是因为在倾斜角度过大的情况，会使得该双面太阳能面板13相对于水平面过于倾向于垂直，使得太阳光的入射角度过小，甚至让反射后的太阳光线无法入射至该背光面132，进而让双面太阳能面板13整体受旋光性降低。由上述，便可得知该倾斜角度θ在不大于40度时，便能使该双面太阳能面板13发挥优良的效能。
以上虽已参照附图来详细说明本发明各优选实施方式，但本发明不限于上述实施方式。本发明所属技术领域的技术人员应当可在本发明的权利要求所记载的范围内做各种变化、改良或组合，且可明了这些当然也属于本发明的权利范围。
根据本发明的浮筒基座用双面太阳能模块设置结构，便可使双面太阳能模块发挥最佳发电效能，以符合经济效益。
