Abstract
This paper presents a field study for the effect of an active water cooling on the performance of photovoltaic system. Three systems each of 1 m2 commercial mono-crystalline PV panels have been installed on the rooftop of the high institute of engineering in culture and science city at 6 October city in Cairo, Egypt (29.9N Latitude). Two of the systems are cooled using two different geometries of copper pipes(serpentine shape and a novelty structure rectangular helical shape) are attached in the backside of the PV module to allow water flowing below it using three different of flow rates (2,4 and 6 L/min) and compared with the uncooled panel. The results illustrate that arise in average electrical efficiency from 8.54% to 10.88% with performance improvement percentage 27.4% at 6 L/min flow rate. The average electrical efficiency increases from 8.54% to 10.17% for serpentine shape and 8.54% to 10.88% for rectangular helical shape at 6 L/min.
