Water is necessary for human survival, individuals consume between 20 and 50 liters of clean water each day for drinking, cooking, and other household activities. Contaminated water is not only unsanitary, but also dangerous to one's health. The main aim of this study is to reduce this problem and to improve the productivity of fresh water.The primary objective of this study was to explore and develop the design for a solar still system with PTC that has a positive effect on the cumulative productivity. The work done theoretical and experimental under the climatic circumstances of Najaf city in Iraq (32° 1' N / 44° 19' E). theoretically the best design for the single solar still is selected by a simulation was made in the COMSOL 5.5 program byuse of two designs of heat exchanger, one of which winding is 8-pipe and the other is a incorporator (absorber plate and pipes). as well as to improve productivity. Nanofluids are used as fluids that runinside the tubes. Using a heat exchanger inside the solar still which is anincorporator (absorber plate and pipes), we will get the highest temperatures from the winding heat exchanger. The highest water temperature inside the solar still when using the heat exchanger incorporator (absorber plate and pipes) was about 92.53⁰C and the temperature of the inner glass surface was 79.651⁰C at 2:00pm, higher than the windingheat exchanger temperatures of 86.78⁰C and 72.472⁰C, respectively. Also, the productivity of distilled water when using anincorporator (absorber plate and pipes) heat exchanger is higher than the other heat exchanger, reaching 5.35017 Kg/m2/day. While the productivity when using a winding heat exchanger is 4.5 Kg/m2/day.In this study, experiments are conducted from March to June. The results showed that when using the single solar stillonly, the highest productivity of distilled water was obtained in May at 4.16 kg/m2/day and the thermal efficiency was 36.31%. A higher productivity is obtained when combined with PTC of 6.83382 kg/m2/day under very close weather conditions, and at a thermal efficiency of 46.24%. The results of the comparison showed that, when using the nanofluid as a working fluid flowing inside the Parabolic Trough Collector (PTC) receiver tube, the outlet temperatures were rising for thesame comparison days with an increase in the productivity of distilled water. The productivity improvement rate was 34.217%. The heat efficiency also increases, reaching about 62.14%.
