The output power of the photovoltaic panel grows with increasing irradiation, while the panel temperature rises with increasing irradiation, resulting in output power loss and a shorter panel life. The study aims to increase solar radiation absorption and maintain a low-temperature panel. Two variations of multiple reflectors as irradiation concentrators and a partially submerged heat sink are investigated experimentally for excess heat dissipation from FPV through air and water media. Compared to a standard panel, the addition of reflectors 0.75 and 1 times the width of the panel, along with the addition of a partially submerged heat sink, increases the power output by 2.44 W and 3.80 W and decreases surface temperatures of 3.21°C and 1.76 °C, respectively. Finally, we conclude that adding the multiple reflectors and a partially submerged corner heat sink has good performance in increasing the power output and maintaining the temperature of the panel is low. © Published under licence by IOP Publishing Ltd.
