摘要
传统固定可调支架系统全寿命周期选用一种固定调节策略,即全寿命下每年的调节次数不变,然而因为全寿命周期组件的衰减和人工调节费用的增加,该调节方法并不是最优策略。基于目前常用的折现后的损益模型,以合肥阳光新能源科技有限公司格尔木项目数据为例,分析确定经济效益最优的合理调节方式,结果表明:全寿命周期内前8年选择每年4次调节,随后选择每年3次调节可以使效益最优。
The traditional fixed adjustable bracket system uses a fixed adjustment strategy throughout its life cycle which means the number of adjustment time per year is unchanged in the whole life cycle.However,because of the degradation of PV panels and the increase of manual adjustment cost,the traditional method is not the optimal strategy.Based on the discounted profit and loss model,it analyzes and determines the reasonable adjustment method wiTHthe best economy based no the data of Golmud Project of Hefei Sunshine New Energy Technology Company Limited.The results show that adjusting 4 times per year in the first 8 years and adjusting 3 times per year in the following years of the whole life cycle can optimize the benefits.
