摘要
在地面大型光伏电站中,平单轴跟踪支架可增加光伏组件接收到的太阳辐射量,但也会增加光伏电站的占地面积。对比分析平单轴跟踪系统在有无逆跟踪技术情况下的发电量和占地面积,结果表明在占地面积相近时逆跟踪技术可有效提升发电量,在发电量相近时逆跟踪技术可有效降低占地面积。
In large photovoltaic power station on the ground,the horizontal single axis tracking bracket can increase the solar radiation received by the photovoltaic module,but it will also increase the area of the photovoltaic power station.In this paper,the power generation and occupation area of the horizontal single axis tracking system with/without backtracking technology were compared and analyzed.Results showed that backtracking technology could increase the power generation effectively when the floor area was similar or could effectively reduce the floor area when the power generation was similar.
