Abstract:
This paper highlights different cooling techniques to reduce the
operating temperature of the PV cells. This review paper focuses on the
improvement of the performance of the small domestic use PV systems by
keeping the temperature of the cells as low as possible and uniform.
Different cooling techniques have been investigated experimentally and
numerically the impact of the operating temperature of the cells on the
electrical and thermal performance of the PV systems. The advantages and
disadvantages of ribbed wall heat sink cooling, array air duct cooling
installed beneath the PV panel, water spray cooling technique and back
surface water cooling are examined in this paper to identify their effective
impact on the PV panel performance. It was identified that the water spray
cooling system has a proper impact on the PV panel performance. So the
water cooling is one way to enhance the electrical efficiency of the PV
panel.
