Renewable energy will be the leading source of power on the upcoming days. Solar irradiation is one of the most convenient sources due to abundance in nature. Right now scientist are facing challenges to mitigate the heat induced by the solar panel during the conversion process. Excessive heat degrades the electrical property of photovoltaic panel thus resulting in reduced efficiency. To improve the efficiency different cooling techniques have been introduced namely active and passive cooling. It is really important to select the right cooling technique while developing the PV panel. It is found that, passive cooling technique is more preferable in-terms of operating cost, ease of use and reliability.
