Experimental Study and Modeling the Behavior of a Solar Water Heater Tested At the Region of Adrar, Algeria

We presented in this study an experimental and theoretical study of a solar water heater (SWH), tested at the hot region of Adrar (Algeria). The SWH was composed essentially with a solar collector and a water storage tank. The experimental work allowed following the variation of the temperatures of the most important components of the SWH, which are the glass and the absorber. The results have shown that 80째C are reached with around 2 hours of inertia. The theoretical study focused on the effect of withdrawal. The efficiency of the system was: 32.89%.
