Water is a necessity that cannot be separated from human life. Water is used in human daily activities such as cooking, bathing, washing, and especially for drinking water. However,some of the water have been contaminated by soil, germs, bacteria or small solids. And most of the energy sources used come from fossil fuels, which is non- renewable energy and are not environmentally friendly One method that can be used to obtain clean water is by solar still desalination, but the problem is low rate of fresh water production. The process of increasing the rate of fresh water production can be carried out if mathematical modelling that can explain the desalination processwell has been obtained. The objective of the present research is to evaluate the commonly used model (Dunkle, Chen, Clark, Adhikari, Kumar Tiwari, Narjes, Rahbar) in terms fresh water productivity, and the mathematical model was validated using experimental data which was carried out for three days. The results showed that of the 7 equations evaluated, the equations that were close to the experimental data were different for the three test days, and had a high percentage of error in fresh water productivity.
