本文对基于PERC技术的地面安装光伏电站进行了生命周期评估(LCA),比较了两种不同的安装配置(单轴跟踪器和固定结构)和两种不同的地点(意大利北部和南部)。主要结论如下: 1. 相比固定结构,使用单轴跟踪器可以降低特定环境影响的17%,尽管其生产阶段需要更多的原材料和能源。 2. 地点对结果有显著影响,南部地点(年辐射量约1819千瓦时/平方米)的特定环境影响明显低于北部地点(年辐射量约1368千瓦时/平方米)。 3. 相比常规的铝背场(Al-BSF)技术,PERC技术在11个评估类别中有7个显示出超过15%的改进。 4. 生产阶段是整个生命周期的关键热点,特别是硅锭生产中的能源消耗。 5. 本文使用的PERC模块生产数据来自制造商,与文献中的数据相比,显示出显著的能源和原材料消耗减少。 6. 本文的LCA结果与最新的PERC技术LCA研究一致。
光伏PERC技术的环境影响评估如何? 不同安装地点对光伏PERC技术环境影响有何影响? PERC技术与传统Al-BSF技术相比有哪些优势?
