Liquid cooling systems circulate a heat-transfer fluid through channels on the back of solar panels, absorbing heat and cooling before recirculation. Additionally, phase-change materials (PCMs) can be integrated into solar panel designs to regulate temperature by absorbing excess heat during the day and releasing it at night.
An increase in the operating temperature of photovoltaic (PV) panels caused by high levels of solar irradiation can affect the efficiency and lifespan of PV panels. This study uses numerical and experimental analyses to investigate the reduction in the operating temperature of PV panels with an air-cooled heat sink.
A temperature decrease of one degree Celsius results in a voltage increase of 0.12 V for polycrystalline PV panels. In this case, the temperature coefficient is 0.12 V/C. At any given temperature, a given material's voltage can be estimated by using Eq.
The results showed that the average temperature increase of the PV panel due to the detected effect of flow separation ranged from 5 °C to 9 °C, which means that the estimated degradation of the electrical efficiency of the PV panel could range from 2.5 % to 4.5 % on average.
