Cooling Techniques Used for Photovoltaic Panels: A Review | Original Article

ABSTRACT:

A brief review of various techniques used for cooling of solar Photovoltaic panels is presented.  The operating temperature of PV module is an important parameter which influences the performance of PV panel. A small portion of solar energy is converted into electrical energy whereas major part of solar energy gets converted into heat which raises the temperature of panels and consequentially reduces efficiency. The reverse saturation current of a solar cell increases rapidly with temperature which decreases the cell voltage.
