Abstract: Based on observation data of global solar radiation(GSR) at 3 meteorological stations and sunshine data at 55 meteorological stations during 1981-2014, distribution of solar radiation resources in Liaoning Province is evaluated. Reliability of GSR data from NASA in the same area is also analyzed. The annual mean GSR in Liaoning province is 4 950 MJ/m-2 with decreasing trend from northwest to east area. The maximum value of GSR(5 421 MJ·m-2) is in Jianping town located in the northwest of Liaoning, and the minimum value (4 506 MJ·m-2) is in Xinbin county located in east. The solar energy resources is stable. The number of continuous days without sunshine is less than 6 in most areas of Liaoning Province with increasing trend from northwest to southeast. The northwest region of Liaoning has the highest predominance in solar energy utilizing. Compare to observation data, the annual mean GSR from NASA data is significantly bigger (around 15%), which should be used cautiously.
