Today, acquiring potable water may be challenging, particularly for residents who reside in rural and coastal areas. Those who procure underground water must first filter it before consumption. Since solar energy is plentiful, environmentally friendly, and free, desalination and water purification can be accomplished using solar stills. However, the production of solar stills is relatively low. This paper aims to ascertain the efficiency of a solar still with nanocrystalline coating on the evaporator basin and the trial will be performed under Malaysian weather conditions. Three solar stills of varying types of evaporator basin coatings were fabricated and tested. Results showed that the Co-Ni-Fe nano-coated solar still generated the highest amount of condensation/evaporation ratio of 40% and a condensate volume of 30 ml.
