Exergetic analysis and parametric study of multi-crystalline solar photovoltaic system at a typical climatic zone

This communication deals with the performance evaluation and parametric study of multi-crystalline solar photovoltaic module using energy and exergy analysis for different months of the year at a typical climatic zone in north India. Three different efficiencies viz. energy, power conversion and exergy have been calculated and plotted against time based on hourly solar radiation. All the three efficiencies for the month of February have been found to be the highest among all the months analysed and presented in the study. The energy efficiency for the month of December is found to be the least; however, the exergy efficiency for the month of July is found to be the least. All the efficiencies have been found to be much higher during the morning and evening hours as compared to the noon hours for all the operating months. The energy efficiency is found to be higher than those of the power conversion and exergy efficiencies throughout the year.
