光伏组件横向和竖向布置技术经济对比分析

Technical Economics Comparison Between PV Module Under Vertical & Horizontal Arrangement

为分析光伏组件在横向和竖向布置条件下的技术经济差异,文章以1 MWp光伏发电单元为研究对象,结合内蒙古苏尼特右旗光伏一期10 MWp发电项目的光伏组件设备参数和水文地质条件,分别建立了光伏组件横向和竖向布置发电模型与支撑结构模型,并分析了两种布置方式在总体经济指标上的差异。结果表明,对于平坦地区光伏电站,光伏组件采用竖向布置在经济性上略优于横向布置,但二者相差无几。然而,对于山地、屋顶、分布式光伏电站,因光伏阵列间距较小引起遮挡严重时光伏组件的布置,则需要专题分析。

To analyze the differences of PV module under vertical and horizontal arrangement in technical economics,1MWp PV array generating capacity models and support structure models were promoted based on the PV module parameters and the geological and hydrological conditions in Sonid Right Banner of Inner Mongolia.According to the results,PV module under vertical arrangement is slightly prior to the one under horizontal arrangement in technical economics.
