Study of Inereasing Solar Domestic Hot Water System Efficiency

Abstract

Solar domestic hot water systems are gaining acceptance worldwide including in Palestine, the system constitutes simple design and can be easily manufacturing. In this project many tests were done to find the performance of the solar domestic hot water system and increase its efficiency by increasing the thermal performance of the flat-plate solar collector, and by dividing the commercial storage tank into multi storage tanks. However , this project developed a new model system that is more efficient than the commercial one, because the period that needed to heat the 50 liter storage tank is less than the 200 litter, especially in the morning period , on other hand , the management and the control panel added some efficiency to the system by storing the hot water inside the tank and using it when the sun radiation is decreased.
