Abstract : The increasing global demand for energy, coupled with the environmental consequences of fossil fuel consumption, has intensified the search for sustainable and renewable energy sources. Among these alternatives, solar energy has emerged as one of the most abundant, clean, and viable options, particularly in regions with high solar radiation such as Nigeria. Solar energy collectors are the main component of solar water heating systems, therefore evaluating their thermal absorption performance and efficiency are of utmost important. This research aims at investigating the thermal energy efficiency of different area of galvanized iron sheet absorber solar water heater in temperate climate of Sokoto State, Nigeria. This was achieved by outlining specific objectives that guided the study. These are; to investigate the mean thermal energy absorption performance of two solar collectors with different areas; to determine difference in thermal energy output of the solar collectors’ base on area and to investigate the mean thermal energy efficiency of two solar collectors with different areas. Solar water heating systems were constructed based on some design assumption and the set up was put in place in accordance with the latitude of the location. The required parameters were measured and recorded from the hours of 9:00am to 16:00pm with an interval of 30minutes for six (6) days and the analysis was carried out base on the average data collected using descriptive statistics and a paired sample t-test.
