现有太阳能发电组件的封装形式主要有玻璃基组件和柔性组件。玻璃基组件是晶硅、非晶硅太阳能组件常用的封装技术，采用玻璃前面板和金属背板对太阳能电池进行封装，技术较成熟，但产品应用安装时需额外安装金属支架系统，以便于固定在屋顶或地面，总体质量很重。柔性组件是一种新型的太阳能组件，其最大特点是可弯曲，可直接贴装在立面、弧形棚面等位置，单位质量仅为晶硅/非晶硅玻璃基组件的三分之一。
本实用新型基于柔性太阳能发电技术及储能技术，为道路隔音系统提供电力供应。具体地，本实用新型的多功能道路隔音系统采用柔性太阳能发电组件，利用柔性太阳能发电组件的可弯曲特性，可实现在垂直立面、弧形悬伸式曲面、跨越式拱面等各种形式的道路隔音障表面的贴装。优选地，柔性太阳能发电组件采用可弯曲的铜铟镓硒(CIGS)作为光伏转换材料，具有良好的发电效率，因其具有较宽的光伏响应范围，可在清晨、傍晚、阴雨天等弱光照条件下发电。柔性光伏组件采用乙烯-四氟乙烯共聚物(ETFE)等轻质非金属材料进行封装，在兼顾环境耐候性能的同时，具有更轻质、可弯曲的特点。
柔性太阳能发电组件可根据用电设备要求进行串联或并联，通过光伏控制器最大功率跟踪技术(MPPT)的调节，可为用电设备提供能源，并对电池进行充电。电池是发太阳能电系统的储能装置，在日照条件下收集剩余太阳能发电， 在太阳能发电不足提供而外的能源保障。本实用新型中采用锂电池，对较高/低温度环境具有很好的适应性。
本实用新型所采用的柔性太阳能发电组件的尺寸可根据作为衬底的隔音板的标准外观尺寸进行定制，例如均可采用交通行业标准进行制作，在隔音系统整体组装前，可预先在隔音板上贴装柔性太阳能发电组件构成标准件，等待安装。
作为一种优选方案，本实用新型的光伏隔音板采用了发电模块的标准模块化设计，柔性太阳能发电组件预制在光伏隔音板上，每个光伏隔音板上可预制一片或者多片柔性太阳能发电组件，多片柔性太阳能发电组件之间可以串联或者并联。并且，一个或者多个光伏隔音板构成一个标准发电模块(本文中也称作“标准跨”单元)。一个“标准跨”单元可由1至10个预制的光伏隔音板构成，形成最小发电系统。其中，所述的多个光伏隔音板之间可以相互串联；或者，也可以每几个串联后形成一个组串，组串之间再并联。
本实用新型的多功能可预制道路隔音系统根据不同的交通设备使用场景，配置了离网储能电源或并网电源两种方案。根据用电需求，采用“标准跨”单元设计，并配置储能装置/系统、光伏控制器、离网电源，可形成独立的、具有储能能力的离网发电系统，供给隔音系统中设备用电；也可级联多个“标准跨”，配置汇流装置、并网逆变器，形成中大型可并网分布式发电系统，供给附近用电设施及建筑的发电系统，多余电量可输送至公共电网，从而起到道路侧空间利用、节能减排和保护环境的作用。
柔性太阳能发电组件采用背面引线的设计，光伏接线盒直接嵌入光伏隔音板预先设计的凹槽内，线缆从光伏隔音板的中空夹层引出，与相邻隔音板连接 后收纳在隔音板的中空空间内。
光伏隔音板之间的接触面采用U型卡槽和凸起的设计，提高安装精度和固定强度，也实现了光伏隔音板的模块化设计和安装，光伏隔音板预制好后可沿“H”型卡槽便捷地安装于工字钢柱内。
此外，现有技术中，交通领域中越来越多地使用大量的照明、监控、指示等配套电气设施，用电需求明显，新建改建道路的供电线路架设愈加繁重。而本实用新型中，由于采用了太阳能发电组件及发电系统提供电力供应，可以对道路隔音系统集成照明、监控、信息警示多种功能，使其成为一种多功能道路配套保障设施的集成载体。
以下将结合具体实施例对本实用新型的采用柔性太阳能发电组件的可预制道路隔音系统作更进一步详细说明。
实施例一：本实施例涉及一种弧形悬伸式道路隔音系统。
如图1所示，本实施例的多功能可预制道路隔音系统主要包括：支撑基础1，以及固定安装于支撑基础1上的一个或者多个光伏隔音板2。进一步地，支撑基础1包括基座10和工字立柱11，金属工字立柱11固定在基座10上，基座10可以是混凝土基座等。
参考图2、图3和图4所示，光伏隔音板2进一步包括吸音屏障20、封顶吸声构件29、柔性太阳能发电组件21、光伏接线盒22、线缆23、线缆接头24等。光伏隔音板2表面贴装有柔性太阳能发电组件21，光伏隔音板2内部设置有用于引导和收纳线缆的中空空间27，以及用于容纳光伏接线盒22的凹槽28。柔性太阳能发电组件21采用背面引线的设计，光伏接线盒22直接嵌 入预设的凹槽28内，线缆23从光伏隔音板2的中空层引出，与相邻光伏隔音板连接后收纳在内部的中空空间27内，使得整体造型简洁美观，并且起到保护线缆23和光伏接线盒22的作用。
此外，参考图1所示，本实施例的多功能可预制道路隔音系统，还可以包括照明灯，如路灯、LED灯等。此外，还可以包括：道路监控系统，例如无线监控装置，用于监控道路、环境等情况；显示装置，例如LED显示屏等，用于显示实时路况信息或交通拥堵提示信息、天气信息、以及监控信息或者广告信息；以及，通讯中继，等。
本实用新型的光伏隔音板2可以在表面预制柔性太阳能发电组件21，每个光伏隔音板2上可预制一片或者多片柔性太阳能发电组件21。结合图2所示，光伏隔音板2两端分别设有凸起25和卡槽26，本实施例中优选采用U型卡槽。光伏隔音板2之间的接触面通过采用这种U型卡槽设计，提高了安装精度和固定强度。
图4所为本实施例的多功能道路隔音系统的侧视示意图，结合图5、图6和图7的主视图所示，本实施例的光伏隔音板2可以包括下方的垂直立面板，以及上方的弧形悬伸式曲面板。光伏隔音板2预制好后可延“H”型卡槽安装工字立柱11内。其中，光伏隔音板2可沿工字立柱11横向安装(如图5下方以及图7)；也可以纵向安装(如图5上方及图6)；或者一部分横向安装，另一部分纵向安装(如图5所示)，安装方式非常灵活。例如，图7中仅在下方安装光伏隔音板2，而上方位置则可以安装玻璃30，或者广告指示牌等。应当理解，本实用新型中的附图仅为示例性示意图，与本实用新型的多功能道路隔音系统的实际结构并不一定按比例绘制。且，本实用新型中的附图并不构成对 本实用新型的多功能道路隔音系统的结构或者安装形式的限制，本实用新型的光伏隔音板2的安装方式并不局限于附图中所示出的方式，例如，还可以是下方采用纵向安装方式，上方采用横向安装方式，等等。
本实施例通过采用柔性太阳能发电组件，使得光伏发电系统的整体重量较轻，安装比较省力，降低了安装难度，提高了安装效率。
进一步地，本实用新型的光伏隔音板2不仅结构上采用可预制的模块化设计，如图8和图9所示，在发电系统设计上也采用标准模块化设计，即，一个或者多个光伏隔音板2可构成一个标准发电模块。这样，柔性太阳能发电系统可根据应用需求，配置成独立的离网发电系统或者级联并网发电系统，也可配置成双发电模式，兼容离网和并网两种发电模式。如图8所示，独立离网发电系统由采用多片柔性太阳能组件形成的标准跨、充电控制器、锂电池储能装置、离网电源等部分组成，可为照明、指示、监控、通讯等用电设备提供交流电源或直流电源。如图9所示，级联并网发电系统由多个标准跨、汇流装置、并网逆变器等构成，可并网发电。
实施例二：本实施例涉及一种垂直立面式道路隔音系统。
本实施例提供一种垂直立面式道路隔音系统，如图10和图11所示，本实施例的多功能道路隔音系统，与前述实施例的区别仅在于，光伏隔音板2为垂直立面板，不包括弧形悬伸式曲面板。其他关于光伏隔音板的具体结构设计，以及光伏发电系统/储能系统等各部分与前述实施例基本相同，并无本质区别。
此外，应当理解，尽管附图中示出的光伏隔音板2是采用横向安装方式，但本实用新型的多功能道路隔音系统，也可以采用纵向安装方式，或者部分横 向，部分纵向的安装方式。
实施例三：本实施例涉及一种拱形跨越式道路隔音系统。
本实施例提供一种拱形跨越式道路隔音系统(未图示)，其光伏隔音板2包括纵向安装的垂直立面板，以及拱形曲面板。或者，光伏隔音板2为整体的曲面板，该整体的曲面板包括下部的垂直立面部分和上部的弧形曲面部分。其他关于光伏隔音板的具体结构设计，以及光伏发电系统/储能系统等各部分与前述实施例基本相同，并无本质区别。
综上所述，本实用新型的多功能道路隔音系统至少具有如下特点之一：
(1)本实用新型为传统隔音系统电气设备配套的太阳能发电系统提供了一种可曲面贴装的安装形式。柔性组件的可弯曲特性能够满足垂直立面、弧形悬伸式曲面、跨越式拱面等不同形式的道路隔音系统的安装设计需求。柔性太阳能发电组件可直接贴装在立面、弧形、或拱形棚面等隔音系统表面，与照明、信息提示、监控等道路辅助装备就近部署，从而简化电路设计和施工。
(2)本实用新型所采用的柔性太阳能发电组件应用可靠性高：由于组件表面采用软性耐腐蚀表面材料，耐飞沙走石不会被击碎、耐盐碱适应道路融雪剂腐蚀环境；组件背部采用背出线走线形式，使用专用抗老化线缆，且采用隔音板内部走线、内部连接设计，改善了电缆使用环境，提升线缆使用年限。综上，通过采用柔性太阳能发电组件提高隔音系统整体的使用寿命，降低维护难度，非常适合较复杂环境下使用。
(3)本实用新型所采用的柔性太阳能发电组件具有极佳的复杂光条件和 弱光条件下的高综合发电能力，因其具有较宽的光伏响应范围，可在清晨、傍晚、阴雨天等若光照下条件下发电；且组件内部采用发电单元子模块设计和旁路二极管设计，在某个发电子模块被遮挡或损毁时，可屏蔽掉不发电部分，不影响其他发电单元工作。
(4)本实用新型的太阳能发电系统采用了“标准跨”的标准模块化设计。一个标准跨可由1至10个预制的光伏隔音板构成，形成一个标准发电模块，即最小发电系统。最小发电系统可根据用电需求，可形成小型的、独立的、具有储能能力的离网发电系统，亦可多个级联形成大型的、可并网的分布式发电系统。
(5)采用本实用新型的方案，可以充分利用道路两侧的空间，解决交通沿途设备供电问题，亦可实现分布式并网发电；光伏离网/并网发电系统可以用于公路、轨道交通中的信息提示、视频监控、信息监控、通信中继等功能点架设的辅助供电，并可应用于高速休息区，满足用户的移动便携设备甚至电动汽车的用电充电需求。
以上实施例仅用于对本实用新型进行具体说明，其并不对本实用新型的保护范围起到任何限定作用，本实用新型的保护范围由权利要求确定。根据本领域的公知技术和本实用新型所公开的技术方案，可以推导或联想出许多变型方案，所有这些变型方案，也应认为是本实用新型的保护范围。
