一种增加双面组件背面发电量的方法
技术领域
本发明涉及一种增加双面组件背面发电量的方法。
背景技术
常规的太阳能光伏组件有普通背板组件、透明背板组件、全玻组件等几大类，双面发电的太阳能电池片目前多用于应用在全玻组件中，一部分阳光通过组件正面的钢化玻璃到达电池片的向阳面，有一部分阳光通过封装玻璃或直接照射在地面或草地，并经过地面或草地反射到电池片的背光面，这种方式虽然能反射一部分阳光，但是由于地面和草地的反射率较低，因此无法很好地利用双面电池的背面进行发电。
发明内容
本发明的目的在于提供一种结构合理，可有效增加发电量的增加双面组件背面发电量的方法。
本发明的技术解决方案是：
一种增加双面组件背面发电量的方法，包括由双面发电太阳能光伏组件组成的地面电站，其特征是：在所述地面电站的地面铺设增加反光的材料，提高地面的反射率；且在双面发电太阳能光伏组件的背板玻璃内表面，镀有ETFE陷光膜，增加背板的透光率。
所述增加反光的材料为贝壳粉。
本发明结构合理，可有效增加发电量。
附图说明
下面结合附图和实施例对本发明作进一步说明。
图1是本发明双面发电太阳能光伏组件的结构示意图。
具体实施方式
图1中从前到后分别是：2mm钢化镀膜玻璃/ETFE陷光膜/EVA/N型双面电池/EVA/透明背板。
一种增加双面组件背面发电量的方法，包括由双面发电太阳能光伏组件组成的地面电站，在所述地面电站的地面铺设增加反光的材料，提高地面的反射率；且在双面发电太阳能光伏组件的背板玻璃内表面（即面向电池的一面），镀有ETFE陷光膜，增加背板的透光率，增加正面、背面的光吸收。
所述增加反光的材料为贝壳粉。
