“Experimental Investigation of Photovoltaic Panel Cooling Using Passive Inserts”

Heat Power Engineering (M-tech)

The performance of PV panel depends on the environmental factors, which is solar radiation and operating temperature. These environmental factors will be reduced the effectiveness of PV panel due to increase in operating temperature of PV panel. To improve the performance of Photovoltaic cell different types of augmentation technique are used which include active, passive and combine technique. The passive technique is widely used because it is not required extra power. In passive technique use twisted tape or wire coil different type of insert's which is placed in flowing fluid in tube then turbulence will create. Then laminar flows gets convert in to turbulent flow which result increases in heat transfer rate is used to overcome the problem of low efficiency of Photovoltaic panel with water flow to the backside of PV panel. This water cooling mechanism is one way for maintaining a low operating temperature during its operation period. The experimental results mentioned that the decrement of operating temperature and increase the power output of the PV panel with water cooling mechanism based on different fixed of solar radiation.
