Abstract

Fins enabled Phase Change Material (FPCM) has potential to take away the thermal energy from photovoltaic (PV) and increase the efficiency. This study analyses the PV-FPCM arrangement and presents a mathematical model. The arrangement is studied under various azimuths of wind, its flow rates, temperature of surroundings, phase change temperature and dimensions of FPCM confinement. The duration of power improvement of PV using FPCM, power production, efficiency improvement and Power-Voltage (P–V) curves are reported. The outcomes convey that as azimuth of wind changes from 75° to 0°, the duration of power improvement elevates from 6.1 h to 7.3 h for 5 cm deep FPCM confinement. It increases from 4.9 h to 5.8 h for 4 cm deep FPCM confinement. Moreover, decrement in wind flow rate from 6 m/s to 1 m/s, contracts the duration of power improvement from 7.8 h to 6.1 h.
