An investigation of the solar distillation using a solar collector with a graduated absorbed surface has been utilized in order to improve the solar still performance. The solar collector is contained on graduated absorbing surface with 25 steps. Absorbing surface made from copper plate and dye by a thermal black pigment to increase the solar absorption. The top of the solar collector is covered by a glass with 4mm of thickness. While, the other side surfaces of the solar collector are made from the transparent plastic with 6mm of thickness. Also, Aperture area of the solar collector was 0.4526 m2. Experiments had been carried out in Baghdad (33.3˚ N latitude) during May in 2019 to investigate the performance of the still. The results appeared the maximum water production that reached up to 486 ml at the time interval between 12.30 and 1.00 pm, while the total thermal solar collector efficiency was 36%. The proposed method succeeded to reduce the TDS from 679 ppm to 39 ppm. for inlet water and outlet pureed water respectively, and the volume distilled water production was 3696 ml for the time from 7.30 am to 4.00 pm.
