Abstract: Investigations were performed on one slope solar unit with 17° inclination for condenser. Important components of the experimental setup are solar desalination unit, parabolic concentrator. Dimensions of the GI basin are 0.7 m length, 0.7 m width, 0.381 m height for the back rectangular face, 0.11684 m height for the front rectangular face. A hollow spherical absorber of 0.65 m diameter containing water is connected to the still. Spherical absorber is heated by a parabolic concentrator whose upper surface is attached with aluminium foil. Due to variation of temperature of water in the absorber and still basin Thermosyphon effect is initiated and water is circulated naturally. All the inside faces of the basin are coated with matt black paint and the experiment was carried for 0.03 m, 0.04m, 0.05m, 0.06m depth of brackish water. The volume of the brackish water was measured by a grading container while the distilled water was measured by a measuring jar. The optimum depth for still attached with absorber is found to be 0.05m and for still without absorber is found to be 0.04 m. Yield collected for still attached with absorber is 2.85 liters and for still without absorber is 2.1 liters. This unit can be installed in and around Vijayawada location as abundant solar radiation is available for nearly nine months in a year.
