Energy and Exergy Analysis of Polycrystalline PV Module

Abstract

The present study focuses on the Energy and Exergy analysis of polycrystalline PV module. The experiment was assessed during the month April 2021. Solar PV system is very versatile technology that generates electricity when solar radiation is incident on the panel. Such solar PV system can be established on free unused surface of roof and barren land etc. The energy and exergy analysis was done in order to get better insight in performance evaluation. Different parameter of the system that was calibrated includes PV module energy efficiency, exergy efficiency, fill factor, exergy loss rate, and energy loss rate. The variation in energy efficiency and exergy efficiency with respect to module temperature, ambient temperature, and wind velocity was also done. According to the data obtained maximum energy efficiency was 23.6% and exergy efficiency was found out to be 12%. It was concluded that module temperature should be maintained at 35℃ for optimum performance of the solar PV system. It was observed that exergy analysis give a more realistic performance evaluation of solar PV system and it depends on difference between module temperature and ambient temperature. According to the obtained it was concluded that solar PV systems have high capital cost but low maintenance and low payback period and thus can be a very feasible green energy technology.
