Abstract

Our current work aims to improve the performance of solar water heaters through a new design that maximizes solar energy utilization by using multiple surfaces to receive and absorb radiation during daylight hours. This is achieved by comparing the old design, which has only one surface facing the sun, with the new design, in which the collector's glass panel is pentagonal, allowing it to receive solar radiation from several sides and mimicking the sun's horizontal movement. Additionally, the absorber surface is wavy To make solar radiation absorbed to the greatest extent possible.
