Innovative methods of cooling solar panel: A concise review

Abstract

This article surveys the various mechanisms of suppressing the killing heat in the electrical performance when a high solar irradiance strikes the surface of the solar panel. In addressing this killing heat, suitable technologies of cooling (active and passive) must be adopted to checkmate the abrupt temperature increase in the solar panel. The theoretical and experimental results of previous studies were critically reviewed. The study suggests that the efficiency of solar panel can be improved beyond 45 % provided a suitable cooling technology can be adopted during the design and installation.
