Study on Influencing Factors of Energy Efficiency of Photovoltaic Power Generation Systems From the Perspective of Life Cycle
Energy efficiency of photovoltaic power generation systems is directly related to the effective utilization of clean energy.In order to study the influencing factors of energy efficiency of photovoltaic power generation systems,this paper constructs an index system of energy efficiency influencing factors of photovoltaic power gen-eration systems from the perspective of the whole life cycle,puts forward 18 evaluation indexes of energy effi-ciency influencing factors,and makes quantitative analysis.The results show that,from the perspective of life cy-cle,the overall scores of the three comprehensive energy efficiency influencing factors in the standard layer are as follows:photovoltaic array loss(weight 54.852％)＞maintenance and management(weight 24.09％)＞transporta-tion efficiency(weight 21.06％),and the evaluation results are comprehensive and objective.It is pointed out that the long-term stable operation and efficient maintenance of the systems have gradually become the key factors affecting the energy efficiency of photovoltaic power generation systems.
