A brief review on solar flat plate collector by incorporating the effect of nanofluid

Abstract The design, analysis and installation of solar collectors are the need of time as its application in the existing systems will reduce the use of conventional source of energy which is limited. On other hand, renewable energy source is unlimited and it will continue to exist till the existence of life on the planet earth. The main objective of solar collectors is to absorb heat from solar energy for increasing the temperature of fluid flowing through the solar collector and this heated fluid can be used for different applications namely heating to room in colder region, the heat of fluid can be utilized in cement industry and many other similar applications. This article attempts to provide an overview of the various techniques and improvements which allows the flat plate collectors to absorb as much solar radiation as possible while minimizing losses to the surroundings. It has been observed that the use of nanofluid enhances the performance of solar collectors. At last, recommendations have been provided.
