Active Cooling Of Solar Panels

The temperature of the pv panel before and after cooling is 45 c and 35 c respectively.

Active cooling of solar panels.

There are a variety of ways in which pv panel can be cooled. It is assumed that the maximum allowable temperature of the pv panel is 45 c beyond which cooling of the pv panel should start by water spraying of the panels till its temperature goes down to 35 c. However when the module was operated under active cooling condition the temperature dropped significantly leading to an increase in efficiency of solar cells to between 12 and 14. Hybrid photovoltaic thermal pv t solar system is one of the most popular methods for cooling the photovoltaic panels nowadays 12 13 14.

This video looks at solutions for cooling a solar panel if and when it gets too hot. Scientists from egypt s benha university have proposed an active cooling technique for pv panels based on the use of water and a mixture of aluminum oxide al 2 o 3 and phase change material. A heat transfer simulation model was developed to compare to the actual temperature profile of pv module and good agreement between the simulation and experimental results is obtained. Without active cooling the temperature of the module was high and solar cells can only achieve an efficiency of 8 9.
