The present study focuses on the design and fabrication of efficient solar distillation system. It is more
economical, therefore, to store water rather than store energy. It is beneficial in the cases of unavailability of
electrical energy or fuel energy. Producing fresh water by a solar still with its simplicity would be one of the best
solutions to supply fresh water with no technical facilities.
In this present experimental study, presence of Sodium sulphate (Na2SO410H2O) in water could provide
better yield when compared to that of Sodium Acetate (CH3COONa) and Potasium Dichromate (K2Cr2O7) used as
Phase Change Material. This may be due to the melting point temperature of sodium sulphate (8840C) is higher than
that of sodium acetate (3240C) and Potasium Dichromate (3980C).
