Experimental Study to Determine the Optimal Number of Collectors for Active Solar Still

Abstract

In this experimental study, single basin solar still (SBSS) has a low productivity, to solve this problem some techniques have been used, these techniques consist of using a solar water heater. The main objective of this research was to effectively utilise the solar water heater (SWH) for solar still productivity enhancement and it is working as a hybrid system. The flat plat collector PC) model solar water heater was coupled with a solar still, and the experiments were repeated in 3 to 5 winter days and the results were measured in the same manner for each day. The results revealed that the productivity of the still was increased 87% when it was coupled with one and was decreased 20% and 50% when it was coupled with two and three solar collectors respectively under winter condition in Ouargla (31.95°N,5.4°E), south of Algeria...
