【摘要】 评估光伏系统的效益时,能量偿还时间是重要指标之一。能量偿还时间取决于光伏系统在寿命周期内输入的全部能量与系统运行时每年所产生的能量。文章介绍了国际上一些研究的情况和结果,并对于中国28个主要城市的能量偿还时间进行了计算和分析。更多还原

【Abstract】 Evaluation of the effectiveness of photovoltaic system,the energy-back time is one of the most important indicators. The energy-back time is depending on the PV system in the life cycle of all inputs of energy and the system is running the energy generated each year. This article describes a number of international studies and results,And energy-back time of 28 major cities in China is calculated and analyzed.更多还原
