Abstract：Based on the observation data of 9 meteorological stations in Guangzhou and Shaoguan from 1981 to 2015,the distribu.tion characteristics of solar energy resources in Shaoguan area were calculated,analyzed and evaluated using climatological statistics,linear trend analysis and meteorological industry standard concerned.The results showed that the solar energy was abundant in Shaoguan.There was not a significant linear variation trend in solar radiation from 1981 to 2015.The solar radiation was rich in summer while it was low in winter.The monthly mean radiation was the highest in July and the least in February.There was difference in the annual solar radiation among areas,with the highest in Renhua and the lowest in Lechang.The linear trend of annual sunshine hours was also not significant from 1981 to 2015.The sunshine hours in summer were more and less in spring.The monthly mean sunshine hours were the highest in July but the least in March.The annual sunshine hours were the most in Renhua,and the least in Lechang.The mean days of yearly average sunshine hours higher than 6 h were 139.6 d.Although exploitation value of solar energy resources was common in Shaoguan area,the exploitation value was high from July to December.The solar energy resources were relatively stable,the number of the days when sunshine hours reached 6 h in July was 18.2 d,which was 3.96 times than that in March.The exploitation and utilization of solar energy resources is feasible in Shaoguan area.
