Demand on fresh water usage for agricultural, industrial and domestic purpose is increasing both in urban and rural areas. This is because of everlasting increase in population. The major health issue in these areas has created a challenge to the mankind. Now there is a need to develop a new device which fulfills the health issue. The present work aims in evaluating the performance of solar distillation unit (i.e. Solar Still) with various slope angles at Hyderabad latitude (at Sultan Ul Uloom Education Society Campus, Hyderabad). Experimentation work is carried on the fabricated solar distillation unit with slope angles under different climatical condition from January starting day to the last day of June. Using solar calculations radiation on these days is calculated. The efficiency of solar still and energy is obtained from the amount of water collected from the still throughout the day from10:00AM to 04:00PM, was observed to be around 12% high with 35o slope angle for desalination of samples of ocean water.
