Water is the most essential element for all human activity on Earth. Clean water is the issue encountered most regularly by all living organisms on earth. The majority of the world's water is in the oceans, thus it cannot be used for human use. Providing potable water from seawater or contaminated water poses a difficulty in remote places where grid connectivity is typically unavailable. Desalination technology solutions are highly lucrative and assist in meeting the rising need for clean water. Desalination is the most effective method for meeting clean water needs. In contrast, solar desalination's effectiveness as a water purifier is rather modest compared to other procedures. PCM Phase Change Material (PCM) can be used as a heat storage to boost the water production of a solar still desalination unit. PCM paraffin wax with a melting temperature of 52 °C was put over a basin of 0.95 m by 0.92 m by 0.07 m and filled with PCM paraffin wax in the shape of stainless-steel balls submerged in sea water. This study aims to assess the impact of PCM mass on water production and equipment efficiency in solar desalination systems. Observations were made to assess the influence of PCM mass fluctuations on solar still desalination devices and experiments without PCM were compared to identify the research methodology. Based on test findings without PCM and PCM mass variations of 0.86 kg, 1.72 kg, and 2.58 kg, water production can be increased by an average of 17.03%, 14.53 %, 18.88%, 17.61 %. The use of heat storage material (PCM) can keep a steady temperature for a longer period of time, hence increasing the productivity of each system by 951 ml (without PCM), 811 ml, 1054 ml, and 983 ml, respectively. The decrease in output of 0.86 kg was caused by a continual shift in irradiation intensity, which dropped significantly and was influenced by the low mass of PCM, resulting in less heat energy stored. The rate of heat transmission from PCM to surrounding water is related to the temperature of the water.
