This review paper provides a thorough analysis of cooling techniques for photovoltaic panels. It encompasses both passive and active cooling methods, including water and air cooling, phase-change materials, and various diverse approaches.
For three PV panels with the cooling system, this voltage is shifted to about 17 V. It is clear that the use of a water spray cooling system causes to shift the point with the maximum output power to a higher voltage. Fig. 9 discloses the I–V characteristic curves for four cases.
The results show that as compared with the case of non-cooled panel, the maximum electrical power output of the photovoltaic panel increases about 33.3%, 27.7%, and 25.9% by using the steady-spray water cooling, the pulsed-spray water cooling with DC = 1 and 0.2, respectively.
It should be noted that the reflection of electromagnetic radiations by water film in the PV panel with cooling system is small. However, during the transmission of electromagnetic radiations through the water layer, a portion of the electromagnetic spectrums may be absorbed by the water molecules.
The results of the photovoltaic panel with the pulsed-spray water cooling system are compared with the steady-spray water cooling system and the uncooled photovoltaic panel. A cost analysis is also conducted to determine the financial benefits of employing the new cooling systems for the photovoltaic panels.
Jakhar et al. used the water as the coolant in the PV panel. They set the water channels at the rear of a PV panel. Their results showed that this system can increase the efficiency of the PV panel. Chandrasekar and Senthilkumar cooled down the PV panels by the heat spreaders in conjunction with the cotton wick structures.
