RESEARCH ON DIFFERENT INSTALLATION TILT ANGLES AND ECONOMICS OF PV POWER GENERATION SYSTEM BASED ON PVsyst
摘要
Abstract
In response to the issue of the economic impact of different installation tilt angles of PV modules on PV power generation projects,this paper takes a 1 MW PV array installed in a ground PV power generation project in Dezhou City,Shandong Province as an example.Under the premise of no shadow obstruction from the front and rear rows of PV arrays during the period of 09:00～15:00(local real solar time)every day,the theoretical optimal installation tilt angle of PV modules is first simulated using PVsyst software.Then,based on this,by reducing the installation tilt angle of PV modules,the impact of different installation tilt angles of PV modules on the installed capacity and economy of PV power generation projects is studied,in order to find the optimal installation tilt angle of PV modules when the economy of PV power generation projects is optimal.The research results show that:1)The theoretical optimal installation tilt angle for the PV modules of this PV power generation project is 28°,provided that there is no shadow obstruction from the front and rear rows of PV arrays during the period of 09:00～15:00(local true solar time)and the project footprint remains unchanged.2)On the basis of the theoretical optimal installation tilt angle in PV module,for every 1° decrease in the installation tilt angle of PV modules,the footprint of a single PV module and the spacing between the front and rear rows of the PV arrays decrease accordingly,and the total installed capacity and power generation capacity of PV modules increase accordingly.3)Under the same footprint,each unit construction cost of a PV power generation project corresponds to the optimal installation tilt angle of the PV module that minimizes its LCOE.As the reduction of unit construction cost of PV power generation projects gradually increases,the installation tilt angle of PV modules corresponding to the lowest LCOE gradually decreases.关键词
