Abstract
With the tightening of domestic land policies and increasingly constrained land availability for photovoltaic plants,complex terrains have become the primary site conditions for photovoltaic project construction.Taking a photovoltaic plant project in Guigang City,Guangxi Zhuang Autonomous Region as a case study,this paper conducts an in-depth exploration of construction strategies for photovoltaic plants under complex terrain conditions.By analyzing site characteristics,multiple support structures and PV string layout schemes were designed,including fixed mounting structures,horizontal single-axis tracking systems,and string configurations such as half-cell and quarter-cell arrangements.The Canela3D software was employed to simulate solar irradiance conditions and validate shading effects across different schemes,ensuring unobstructed module performance.The results show that the installed capacity and annual to-grid energy of the optimal scheme are increased by 15.3%and 12.8%,respectively,compared with the other two schemes,and the land utilization rate is increased by 4.4%and 4.3%,respectively.This study provides scientific guidance for photovoltaic plant construction in complex terrains,facilitating higher power generation efficiency and economic benefits under limited land resources.关键词
