Abstract: Fins are extended surface which increase the heat transfer rate. It is most commonly used in heat exchanger device such as car radiator, computer CPU heat sink and hydrogen fuel cell, etc. Fins increase area of heat transfer in cooling and heating application. Our ultimate aim is to reduce losses present in flat plate collector by conduction, convection and re-radiation. Lots of experimentation has been done to improve the heat transfer rate of solar water heater by adding fins of helical, rectangle, circular, trapezoidal section as well as twisted shape. This paper makes summary of the all previous work on solar FPC with number of geometrical shapes of fins and their effect on efficiency of flat plate collector. As surface area increases heat transfer from fins also increases. So implementation of fin in solar FPC is also a most promising technique that enhances the heat transfer rate through absorber.
