住宅楼屋顶分布式光伏电站安装型式对比分析

Comparative Analysis of Installation Types of Distributed Photovoltaic Power Stations on the Roof of Residential Buildings

本文以住宅楼屋顶分布式光伏电站为研究对象,简要分析了不同光伏组件安装型式对发电量及经济效益的影响。通过控制变量对比和试验模拟分析,组件朝向正南且倾角为最佳倾角时,光照辐射量最高;组件朝向正南且倾角为最小倾角时,组件装机容量最大,发电量最大。通过经济效益分析,在满足基本收益率的条件下,住宅楼屋顶光伏安装倾角为最小倾角时,经济收益最大;安装倾角为最佳倾角时,收益率最高。

Taking the distributed photovoltaic power station on the roof of the residential building as the research object,this paper briefly analyzes the influence of different photovoltaic module installation types on the power generation and economic benefits.Through the comparison of control variables and experimental simulation analysis,when the module faces due south and the inclination angle is the optimal inclination angle,the amount of light radiation is the highest;when the module faces due south and the inclination angle is the minimum inclination angle,the installed capacity of the module is the largest and the power generation is the largest.Through the economic benefit analysis,under the condition of satisfying the basic rate of return,when the inclination angle of the photovoltaic installation on the roof of the residential building is the smallest inclination angle,the economic benefit is the largest;when the installation inclination is the optimal inclination angle,the yield is the highest.
