520			_aWater scarcity, driven by rapid population growth, places significant strain on limited water resources, leading to water quality deterioration and a crisis in access to safe drinking water, particularly in the Philippines. Approximately 9 million Filipinos depend on inadequate, unsafe, and unsustainable water sources, which impacts both rural and urban areas. This study centered on the design, fabrication, assembly, evaluation, and testing of a Small-scale solar-powered desalination system that aims to produce a potable water from seawater sourced collected from Manila Bay Walk. The prototype uses a 200W photovoltaic solar panel to generate electricity, which powers a 500W band heating element wrapped around a 304 stainless steel mini boiler and a heat exchanger. Laboratory tests were conducted to assess the water’s quality, including pH, TDS, salinity, total coliform, thermotolerant (fecal) coliform, and heterotrophic plate count. The results showed that the desalinated water had a pH of 8.31, which falls within the safe range of 6.5–8.5. However, the total dissolved solids (TDS) level was 5140 mg/L, exceeding the acceptable standard of <600 mg/L. The salinity was measured at 3.72 PPT, 15% of salt after desalination which is considered acceptable. Microbial contamination, including high levels of total coliform, thermotolerant coliform, and heterotrophic plate count, rendered the water unsuitable for consumption. Despite these issues, the system produced 200 mL of fresh water per hour, demonstrating its feasibility for localized use. The system was evaluated with a grand mean of 4.34, classified as excellent, confirming its potential for further improvement.
