沙漠环境对光伏组件影响的研究

Influence of Desert Environment on Photovoltaic Modules

笔者探讨沙漠环境中光伏组件的性能表现及其影响因素,提出一系列针对性的改进措施和建议。通过对某沙漠地区的光伏电站进行了为期一年的实地监测,收集了大量关于相对湿度、温度、风速、大气压力和太阳辐射强度的数据,并在实验室模拟了不同沙尘浓度下的光伏组件性能变化。研究表明:沙漠环境中的高温和强辐射对光伏组件有显著影响,而沙尘对光伏组件的影响则更为复杂;相对湿度与辐射强度存在显著的相关性,且沙尘沉降对光伏组件的功率损失率有较大影响;沙尘浓度的增加导致透过率下降,进而影响光伏组件的效率。通过研究,期望能够推动光伏技术在更广范围内的应用,减少对化石燃料能源的依赖,并实现可持续发展目标。

This paper discusses the performance and influencing factors of photovoltaic modules in desert environment,and puts forward a series of targeted improvement measures and suggestions.Through a one-year field monitoring of a photovoltaic power station in a desert area,a large amount of data on relative humidity,temperature,wind speed,atmospheric pressure and solar radiation intensity were collected,and the performance changes of photovoltaic modules under different dust concentrations were simulated in the laboratory.The results show that the high temperature and strong radiation in the desert environment have a significant impact on the photovoltaic modules,while the impact of dust on the photovoltaic modules is more complex;There is a significant correlation between relative humidity and radiation intensity,and dust deposition has a great influence on the power loss rate of photovoltaic modules;The increase of dust concentration leads to the decrease of transmittance,which in turn affects the efficiency of photovoltaic modules.Through research,it is expected to promote the application of photovoltaic technology in a wider range,reduce dependence on fossil fuel energy,and achieve sustainable development goals.
