Abstract
The energy efficiency and exergy efficiency of recommended photovoltaic (PV) array are calculated for Kerman climate. Since energy efficiency and exergy efficiency of PV array is dependent on weather conditions, the recommended PV array energy and exergy have been analyzed in various months of the year to be used in Kerman climate. Also, the wind speed impact on exergy efficiency has been studied in this research. The simulated results were compared to experimental results to confirm the validity of employed relationships and a good agreement was observed between them. Since the model’s results match those of experiments, the model presented in this paper can be used for various weather conditions. An important result of the research was higher accuracy of exergy efficiency calculation of present model relative to past models. Also, energy efficiency and exergy efficiency were almost identical for various months of the year and the PV array can be used to produce a part of required electric power in Kerman climate throughout the year. The annual averages of exergy, energy, and electrical efficiencies in Kerman climate are 12.03%, 16.27%, and 12.14%, respectively.
