挪威国家足球场安装的太阳能装置是迄今为止世界上最大的屋顶垂直双面太阳能装置。
这个284.4 kW的系统包括1242块200 Wp的垂直光伏元件。这些垂直光伏元件由挪威垂直太阳能系统专家Over Easy Solar公司提供。Over Easy Solar公司生产的XM-2 Quattro-200S垂直面板采用硅异质结电池和模块架构,据报道,该面板可提供95.7%的双面转换效率。这些面板的重量也很轻,在屋顶上增加的重量不足11公斤/平方米。
该光伏阵列由挪威Solenergi FUSen公司于今年5月份安装在Ullevaal体育场的沥青屋顶上,安装工作在几天内完成。该光伏阵列的占地面积超过2500平方米,预计每年将产生219,000 kWh的能源。
该装置中的太阳能电池板,其朝向为南方偏东20度,这样的朝向可以在冬季提供更高的能量产出。Over Easy Solar公司表示,通过对其试点项目进行分析后发现,垂直太阳能电池板的单位产出率相较传统的平屋顶解决方案高出20%至30%以上。由于垂直面板的积雪较少,其在冬季也能保持较高的性能。
去年,《光伏》杂志报道了挪威的两个由Over Easy Solar公司提供的屋顶装置,一个是102 kW的双面商业屋顶系统,另一个是45 kW的学校屋顶系统。
