Solar Panel Cooling System

Abstract

This project highlights two different cooling techniques to diminish the operating temperature of the PV cells. This review project focuses on the enhancement of the performance of the small domestic use PV systems by maintaining the temperature of the cells as low as possible. Distinctive cooling practices have been look over experimentally and numerically the bearing of the operating temperature of the cells on the electrical and thermal performance of the PV systems. It was notorious that the water spray cooling system has a proper crash on the PV panel performance. So the water cooling is one way to augment the electrical efficiency of the PV panel. The performance was evaluated under three different cases: (a) without panel cooling, (b) with water cooling on beneath the surface of the panel with copper tube, (c) with water cooling beneath the surface of the panel with jute. The outcome of different cooling cases on the various performance parameters such as voltage, current, power output, pump efficiency and system efficiency has been analyzed and discussed. The results showed that the water cooling on the bottom of the panel and beneath the surface of the panel with jute has considerable influence on performance enhancement when compared to other cases.
