المستخلص: There is a problem of potable water shortage in many parts of the world nowadays. For many developing countries, desalination using solar energy is the solution to overcome this issue. This paper investigates the performance of a solar still using the convex lenses on the glass cover, and radiating surfaces below the lens to increase the solar radiation inside the solar still. The results of this study indicated that using a convex lens and radiating surfaces can significantly increase the daily productivity and the efficiency of the single basin solar still. Experiments were carried out during March 29 to June 6, 2016, at Sabratha Engineering College, Libya. The amount of distilled water was measured starting from 10 A.M to 4 P.M each day. The results showed that the maximum daily productivity of the new still with a convex lens and radiating surfaces was 2.248 liter/day which is higher by 15% compared with the conventional still at the same operating conditions. While the daily efficiency of the modified still was found to be 63.64% at 4:00 PM on May 26, 2016.
