Passive cooling is a widely used method because of its simple equipment, low capital expenditure, low operating and maintenance costs. This paper presents a comprehensive review of recent studies on cooling PV panels passively using heat sinks.
The most common design includes fins, thin aluminium sheets or similar at the bottom of the module, which is responsible for increasing the air duct's radiative and convective heat transfer surface, causing turbulence, and acting as a heat sink. Figure 3 shows a general scheme of how air cooling works for 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. The proposed heat sink was designed as an aluminum plate with perforated fins that is attached to the back of the PV panel.
A liquid coolant, such as water or glycol, is used to cool an active cooling panel. The heat from the panel is dissipated passively by radiative and conductive heat transfer. The cost, efficiency, and simplicity of a cooling approach should be considered when choosing an appropriate approach for analysis [40].

Why do photovoltaic panels need a heat sink?
Heat sinks provide an uncomplex and inexpensive solution for cooling photovoltaic panels that require little or no maintenance and consume no-electricity. A heat sink is practically an element made of metal that is designed to enhance the transfer of heat from its source to the environment by means of natural or forced convection.
Can a heat sink remove heat from PV panels?
Tests have shown that this solution has great potential for passive heat removal from PV panels. Passive cooling using heat sinks can also be found in Mittelman et al. . The research used a heat sink in the form of an aluminium plate with perforated fins attached to the back of the panels.
Do heat sinks affect circulating air in PV panels?
The research used a heat sink in the form of an aluminium plate with perforated fins attached to the back of the panels. The analyses examined the effect of heat sinks on the heat transfer between the PV panel and the circulating ambient air. The heat sink was designed as an aluminium plate with perforated fins attached to the back of the PV panel.
Are heat sinks a good solution for cooling solar panel?
Conclusion Heat sinks are simple and cheap solutions for cooling solar panel. We have passively cooled the solar panel using aluminum heat sinks and studied their influence on the solar panel performance characteristics.
Why do photovoltaic arrays use fins on a heat sink?
According to Fig. 2 (d), fins on a heat sink are used to dissipate heat from photovoltaic arrays . Fins allow the heat sink to absorb and dissipate more heat by increasing its surface area. Photovoltaic arrays can use this cooling technique in hot climates, since the additional surface area keeps them cool and efficient. 4.5.
