An engineering analysis method based on the model of energy loss for photovoltaic array and inverter was proposed in this paper. The operating data of several PV plants is researched applying the PV Power Generation Monitoring System of Jiangsu Province, and the characteristics are concluded. The theoretical calculation method of photovoltaic system efficiency according to the PV stations＇ system structure is deduced. The quantitative analysis clarifies that the PV stations＇ system efficiency is within the range of 80.2%-90.4%. In addition, based on the data of Jiangsu PV generation system platform, the validity and correctness of the theoretical analysis through statistical analysis is verified. The conductor＇s cross section of the PV stations＇ output line being selected according to 80% of the installed capacity will save investment and improve asset utilization efficiency.
