摘　　要：光伏电池板在不同条件下的温度分布是光伏发电领域的研究热点之一,其表面温度分布与光伏电池板倾角α、风向角β和风速V存在密切关系。本文通过实验探究线光源下不同参数对光伏电池板温度分布的影响。结果表明:线光源条件下,光伏电池板存在局部光斑现象;风速V的增大会导致光伏电池板上局部光斑的范围缩小;存在临界倾角使得光伏电池板表面出现局部光斑,并且倾角α的变化会造成局部光斑大小和位置发生变化;风向角β的变化对局部光斑的大小和位置的影响很小;光照强度I的增大会使局部光斑范围增大并且温度升高。The temperature distribution of photovoltaic panel under different conditions is one of the research hotspots in the field of photovoltaic power generation,which is closely related to the inclination angle α,wind incidence angle β and wind speed V when receiving solar radiation.This paper explored experimentally the influence of different parameters on the temperature distribution of photovoltaic panel under the radiation of linear light source.The results show that there exists a local light spot on the photovoltaic panel under linear light source;the increase of wind speed V will lead to the area of local spot to decrease;there is a critical inclination angle of photovoltaic panel that makes the local spot appear,the variation of inclination angle a will cause the position and size of local spot to change,while the change of incidence angle β does slightly;the increase of light intensity I will lead to the size and temperature of local spot to increase.
