Design, construction and experimental testing of solar water heaters under Saharan weather conditions

Abstract

In order to produce hot water, a solar energy collector is investigated experimentally in the current study. Various investigations are carried out in order to highlight the performance of the collector. Determining daily performance for different time periods is also under study. The collector was manufactured using inexpensive materials that are available on the local market. This study aims to encourage rural families to use solar energy to heat water by providing solar collectors. The results revealed that the hot-water temperature at the collector-outlet exceeded the temperature of 50℃, with an average daily yield of about 60%, under the Saharan climatic conditions of the city of Adrar.
