A Review on The Cooling Technique of Solar PV System

Being the most widespread renewable energy generation system, photovoltaic (PV) systems face major problems, overheating and low overall conversion efficiency. The electrical efficiency of PV systems is adversely affected by significant increases in cell temperature upon exposure to solar irradiation.  There have been several ways to remove excess heat and cool down the PV to maintain efficiency at fair levels. A hybrid photovoltaic/thermal system cooled by forced air circulation blown by a PV-powered fan can set up, and a rectangular control volume with cylindrical ends has been built at the back of the PV panel where aluminum fins have been placed in different arrangements and numbers
