Measurement of grid solar PV system in Oman

In this paper the measured results of Desert Type PV, in Muscat governorate in Oman, is discussed and analyzed. Several factors were measured and calculated for one whole year including, solar radiation, efficiency of the modules, temperature of the modules, energy production and number of sunshine hours. It was found that the average efficiency of this type of PV is 15% during the whole year. Although the number of sunshine hours is more during the summer time, the solar insolation is reduced owing to the high temperature. The power production and efficiency during winter are higher due to the reduction in the ambient temperature. From the measurements we can conclude that this type of PV is suitable for harsh weather such as the hot weather in Arabian Gulf Countries.
