摘要：
Based on the field observation data from the large solar farm and the region without PV array in Golmud from October 2012 to September 2013, the characteristics of surface radiation were analyzed. The results showed that the total daily values of upward shortwave radiation and net radiationin the solar farm are 3.54, 8.30 MJ/m2, respectively, while the region without PV are 5.02, 6.34 MJ/m2. The maximum value appears in June, the minimum value appears in December. The maximum difference values of upward shortwave radiation of two sites appears in spring (March-April), the minimum value appears in winter (December-January). The maximum difference values of net radiation at two sites appears in August, the minimum value appears in December. The mean daily albedo at the solar farm is 0.19; the region without PV is 0.26. Annual mean of net radiation in the solar farm is higher than the region without PV obviously, so the solar farm is collecting energy, but the PV array converts part of the radiation energy to electrical energy to output, this can lead the surface layer temperature in the solar farm lower. ©, 2015, Science Press.
