Objective:To design and construct a CdTe thin-film photovoltaic greenhouse grid-connected power generation system in Bengbu and simulate the power generation of the system for 25 years.Methods:Based on the meteorological conditions in Bengbu,Anhui province,the project overview was expounded based on PVsyst software.A photovoltaic grid-connected power generation system was designed and built to determine the photovoltaic module layout,photovoltaic module and inverter equipment selection,and the best inclination module for secondary optimization,predict the first year capacity and the first year of the system loss.Results:Through simulation analysis,it was concluded that the optimal power generation angle of the thin film photovoltaic greenhouse power generation system in this area was 24°,and the comprehensive efficiency(PR)of the system reached 84％.The total power generation of the photovoltaic system in 25 years of operation would reach 1 894 399 kWh,and the average annual power generation would reach 75 775.96 kWh.Conclusion:CdTe thin-film photovoltaic greenhouse had high power generation efficiency and stability under suitable conditions,which provided theoretical basis for practical engineering application.
