Abstract: (1667 Views)
In this paper, the performance of a typical 190 W photovoltaic cell, located in Research Institute of Petroleum Industry, Tehran, Iran, has been studied and evaluated from the energy and exergy point of view. A computer code has been developed for modeling and determining the electrical characteristics of the system such as open circuit voltage, short circuit current, system resistances, maximum power point properties and characteristic curves. The operational and electrical parameters of the system and the environmental conditions such as solar radiation, wind speed and ambient temperature have been experimentally measured and logged on one typical day of May. For the validation of model, the results obtained from the model have been compared with the data reported by the manufacturer as well as the experimental data. The results show that the energy efficiency varies from 11.22 to 13.94 percent during the study period (7:30 AM to 5:30 PM) and its average is equal to 13.19 percent. The exergy efficiency also varies from 14.77 to 16.66 percent during the study period and its average is 15.62 percent.
