江苏昆山地区光伏组件东西坡安装对发电收益的比较分析

Comparative Analysis of the Comprehensive Income of the East and West Slope Installation of Photovoltaic Modules in Kunshan District Jiangsu Province

通过对江苏昆山地区分布式光伏电站东、西坡逆变器发电量与发电曲线的监测、分析、计算,得到东、西坡逆变器发电量情况、发电曲线情况以及综合收益分析。结果表明,西坡屋面比东坡屋面光伏发电系统发电量低约0.49%、电度电价高约1.29%、综合收入高0.35%~0.79%(与度电补贴有关),补贴越低,西坡屋面比东坡屋面综合收入提高的越多。在东西坡屋面建筑上铺设光伏组件时,可以选择优先在西坡屋面铺设光伏系统。

Based on the monitoring,analysis and calculation of the power output and power generation curve of the east and west slope inverters in Kunshan District,Jiangsu Province,the power output,power generation curve and comprehensive income analysis of the East and west slope inverters are obtained.The results show that the power generation capacity of the west slope roof is about 0.49%lower than that of the east slope roof photovoltaic power generation system,the electricity price is about 1.29%higher,and the comprehensive income is 0.35%~0.79%(related to the subsidy of electricity).The lower the subsidy is,the more the comprehensive income of the west slope roof is increased than that of the east slope roof.When photovoltaic modules are laid on the roof of the east and west slope buildings,the priority can be given to laying photovoltaic system on the roof of the west slope.
