Construction of Solar Distiller to Study Its Performance Under Environmental Conditions in Mosul City

Water is a basic necessity for human being along with food and air. Desalination of water by using solar energy is suitable for potable water production from brackish and sea water. This article includes constructing the double inclined roof model and study its performance under the open environmental conditions of Mosul Iraq. The solar distillation unit consist of two main components: transparent glazing cover of 0.004m thickness inclined at 40o in order to obtain extra solar energy, and steel basin had dimension of 0.98m length,0.76m width and 0.15m height. The s tudy includes the still performance in terms of the still efficiency ( ), thecoefficient of performance (C.O.P.) and heat losses from the solar still were also considered
