光伏组件版型对光伏发电系统BOS成本的影响研究
RESEARCH ON IMPACT OF PV MODULE FORMAT ON BOS COST OF PV POWER GENERATION SYSTEM
摘要
Abstract
The BOS cost is a decisive factor in whether a PV power generation project will be implemented.This paper takes a PV power generation project in Riyadh,Saudi Arabia as the research background,and explores the impact of PV module format on the BOS cost of PV power generation systems.First,the influencing factors of BOS costs in PV power generation systems are introduced.Then,following the principle of single variable,taking the two PV module formats G12R-66 and G12-66(hereinafter referred to as"G12R modules"and"G12 modules"respectively)as examples to analyze in detail how PV module formats affect variable BOS costs such as the transportation cost per watt of PV modules,the installation cost per watt of PV arrays,the DC cable cost per watt,and the PV bracket cost per watt.Additionally,the BOS cost per watt under different PV bracket schemes with varying PV module formats is calculated and compared in detail.The research result show that:1)During transportation,the higher the container utilization rate of PV modules,the more pronounced the advantage of transportation cost per watt.The higher the peak power and larger the size of a single PV module,the more bargaining advantage it is for on-site handling and installation of PV modules,as well as installation of PV brackets.Under the same photoelectric conversion efficiency,the larger the PV module size,the less DC cable is used.2)Under specific design conditions,in the fixed PV bracket scheme and the multi motor driven flat single axis tracking PV bracket scheme,the PV bracket cost per watt of two PV module formats is similar,while the G12 module has less DC cable usage and lower PV array installation cost per watt,so its BOS cost per watt is more advantageous.3)Under specific design conditions,in the single motor driven flat single axis tracking PV bracket scheme,due to the low PV bracket utilization rate of the G12 module,its BOS cost per watt is at a disadvantage.After increasing the PV bracket maximum length to make the PV bracket utilization rate of two PV module formats basically the same,the BOS cost per watt of the two is basically the same,and the G12 module has a slight advantage.关键词
