高海拔荒漠地区光伏组件衰减机理分析
Analysis of attenuation mechanism of PV modules in high altitude desert area
摘要
Abstract
Photovoltaic panels is the core component of photovoltaic power generation system, the photoelectric conversion efficiency is mainly affected by environmental temperature, irradiance and soil properties characteristics, but the photoelectric conversion efficiency of photovoltaic panels in high altitude area decay mechanism is not clear. This paper mainly to the PV module as the object research, the parameters of PV modules by I-V curve test instrument, the PV module temperature calculation in practical work, to establish a mathematical model between the photoelectric conversion efficiency and temperature difference, the application of MATLAB software to simulate the data, found that the temperature difference is more than 75 ℃ on the photoelectric conversion efficiency of photovoltaic components decreased more obvious. At the same time, the model is verified by the actual power generation data, and the reasons for the decline of power generation efficiency after the operation of PV modules are analyzed.关键词
