Abstract
This study presents the results of numerical experiments conducted for determining the daily variations of water temperature and useful heat in flat-plate solar water-heating collectors (FSWHCs), with capacitive solar radiation absorbers (SRAs) with bottom absorption of radiation. These absorbers are made as rectangular containers 5–7 cm in thickness from translucent plastics.
