In this work, a sun tracking system application is used for water heating and street lighting in Van. The solar photovoltaic system is designed for a house whose power is 5 kilo-Watts. An experimental setup is carried out for 183 Watts. An optimal variant is chosen with respect to stiffness and lightness conditions. A sun tracking device was used for rotating the solar still with the movement of the sun. A comparison between fixed and sun tracked solar stills showed that the use of sun tracking increased productivity by around 29%. It can be concluded that the sun tracking system is more effective than the fixed system and is capable of enhancing productivity.
