Abstract

Abstract Current experimental work studies the thermal performance of a flat plate solar water collector according to the weather conditions of the city of Ekaterinburg in Russia. All tests were carried within four months and four typical clear days were chosen for each month. Thermal efficiency, useful energy, and water temperatures at the inlet and outlet of the flat plate solar collector have been investigated in this study. The results were collected during summer and autumn have been analyzed to find out the effect of different weather conditions on the performance of the proposed flat solar water collector. The highest efficiency of the solar collector was recorded during midday when the collector receives the highest solar energy intensity and thus the highest rate of useful heat gained. The maximum efficiency observed by 66% in July compared to the other months included in the current study. The results showed good agreement between the previous studies and the current proposed solar water collector in terms of thermal efficiency.
