Description
技术领域
本发明涉及光伏产品技术领域，尤其涉及一种用于光伏瓦的彩色光伏组件。
背景技术
随着我国光伏行业的发展和住宅电力需求的不断提升，促使住宅发电技术和发电产品的快速发展，以满足居民住宅的绿色能源需求。目前，市面上应用于光伏瓦产品的光伏组件，为了达到光伏组件与瓦片视觉上的颜色一致，大都是采用防窥片，通过防窥片色彩的变化来让光伏组件呈现不同的色彩，其不足之处在于，一方面防窥片增加了光伏组件的厚度、重量及材料成本，也不利于在屋顶安装，另一方面防窥片透光率偏低，降低了组件的发电效率，且难以在防窥片上沉积不同颜色、形状的图案。
发明内容
本发明要解决的技术问题是克服现有技术的不足，提供一种结构简单、成本低、重量轻、效率高的用于光伏瓦的彩色光伏组件。
为解决上述技术问题，本发明采用以下技术方案：
一种用于光伏瓦的彩色光伏组件，包括由内向外依次布置的背板、太阳能电池片阵列以及光伏钢化玻璃，所述光伏钢化玻璃的内表面镀有反射膜结构，所述反射膜结构包括保护膜层、以及多层相互平行的彩色反射膜层，所述保护膜层与所述光伏钢化玻璃平行布置，所述彩色反射膜层垂直布置于保护膜层和光伏钢化玻璃之间。
作为上述技术方案的进一步改进：所述彩色反射膜层与所述保护膜层之间设有AG硬化层。
作为上述技术方案的进一步改进：所述保护膜层为PET保护膜层。
作为上述技术方案的进一步改进：所述太阳能电池片阵列上的栅线、焊带和汇流条的表面均设有遮光胶带，所述遮光胶带和所述背板的颜色均与所述太阳能电池片阵列封装后的颜色相同。
作为上述技术方案的进一步改进：所述背板为双面含氟TPT背板。
作为上述技术方案的进一步改进：所述遮光胶带为PET胶带。
与现有技术相比，本发明的优点在于：本发明公开的用于光伏瓦的彩色光伏组件，在光伏钢化玻璃的内表面镀有反射膜结构，反射膜结构包括保护膜层、以及多层相互平行的彩色反射膜层，保护膜层与光伏钢化玻璃平行布置，彩色反射膜层垂直布置于保护膜层和光伏钢化玻璃之间，当人的视线处于可视角度范围内时，彩色光伏组件表面呈现的是太阳能电池片阵列封装后的颜色，当人的实现处于可视角度范围之外时，彩色光伏组件表面呈现的是彩色反射膜层的颜色，且可以通过调整反射膜层的高度、反射膜层之间的间距灵活调整可视角度，无需设置防窥片，结构更简单、重量更轻、成本更低，太阳光可在可视角度范围内入射至太阳能电池片阵列，不受遮挡，保证了组件的发电效率，且在光伏钢化玻璃上沉积不同颜色、形状的图案工艺难度更低，更容易满足不同居民的个性化需求。

具体实施方式
以下结合说明书附图和具体实施例对本发明作进一步详细说明。
图1至图5示出了本发明用于光伏瓦的彩色光伏组件的一种实施例，本实施例的用于光伏瓦的彩色光伏组件，包括由内向外依次布置的背板1、太阳能电池片阵列2以及光伏钢化玻璃3，可采用一体夹胶层压工艺，将三者有效地粘接在一起，满足户外环境条件下的防尘、防水等各方面的防护要求，光伏钢化玻璃3的内表面镀有反射膜结构，反射膜结构包括保护膜层41、以及多层相互平行的彩色反射膜层42(例如瓦片常用的黑色、土黄色)，保护膜层41与光伏钢化玻璃3平行布置，彩色反射膜层42垂直布置于保护膜层41和光伏钢化玻璃3之间。
该用于光伏瓦的彩色光伏组件，在光伏钢化玻璃3的内表面镀有反射膜结构，反射膜结构包括保护膜层41、以及多层相互平行的彩色反射膜层42，保护膜层41与光伏钢化玻璃3平行布置，彩色反射膜层42垂直布置于保护膜层41和光伏钢化玻璃3之间，当人的视线处于可视角度范围内(本实施例中设定为90°)时，彩色光伏组件表面呈现的是太阳能电池片阵列2封装后的颜色(本实施例中采用硅单晶太阳能电池片阵列2，封装后呈现亚光黑色)，当人的实现处于可视角度范围之外时，彩色光伏组件表面呈现的是彩色反射膜层42的颜色(本实施例呈现亚光黑色)，且可以通过调整彩色反射膜层42的高度、彩色反射膜层42之间的间距灵活调整可视角度，本发明无需设置防窥片，结构更简单、重量更轻、成本更低，太阳光可在可视角度范围内入射至太阳能电池片阵列2，不受遮挡，保证了组件的发电效率，且在光伏钢化玻璃3上沉积不同颜色、形状的图案工艺难度更低，更容易满足居民的个性化需求。
作为优选的技术方案，本实施例中，彩色反射膜层42与保护膜层41之间设有AG硬化层43。AG硬化层43硬度高、耐磨性好，透光率高，且不易沾染灰尘、油污。
作为优选的技术方案，本实施例中，保护膜层41为PET保护膜层。PET保护膜又称耐高温聚酯薄膜，耐磨、耐高温，抗老化、抗紫外线性能好。
进一步地，本实施例中，太阳能电池片阵列2上的栅线21、焊带22和汇流条23的表面均设有遮光胶带5，遮光胶带5和背板1的颜色均与太阳能电池片阵列2封装后的颜色相同，从而实现组件上表面全面的彩色效果，具体为亚光黑色。
作为优选的技术方案，本实施例中，背板1为双面含氟TPT背板。双面含氟TPT背板，具有良好的耐候性能、抗老化性能和耐高温性能，且重量轻，仅为传统背板的70％，颜色为亚光黑色，与硅单晶太阳能电池片阵列2封装后的颜色一致，厚度优选0.2mm，光伏钢化玻璃3优选超薄高硬度钢化玻璃，厚度在2mm左右。
作为优选的技术方案，本实施例中，遮光胶带5为PET胶带。PET胶带抗老化、抗紫外线性能好，颜色为亚光黑色，与硅单晶太阳能电池片阵列2封装后的颜色一致。
虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明。任何熟悉本领域的技术人员，在不脱离本发明技术方案范围的情况下，都可利用上述揭示的技术内容对本发明技术方案做出许多可能的变动和修饰，或修改为等同变化的等效实施例。因此，凡是未脱离本发明技术方案的内容，依据本发明技术实质对以上实施例所做的任何简单修改、等同变化及修饰，均应落在本发明技术方案保护的范围内。
