This document presents the results of an investigation into the performance of solar domestic hot water systems in Northern Cyprus. Laboratory and on-site tests were conducted to analyze the effects of collector tilt angle and azimuth orientation on system efficiency. The results show that a tilt angle of 36 degrees performs best overall, with lower angles in summer and higher in winter. East-facing azimuths increase morning performance while west-facing boosts afternoons. Testing found efficiencies of 25-30% in the lab but 15-25% in actual use, highlighting the need for improved installation practices. The study provides guidance on optimizing collector orientation for seasonal hot water demands.
