In this experimental study two basins such as lower basin and upper basin is of size 1000mm×330mm×380mm and 1000mm×590mm×310mm are used. The salted water is used for distillation. Distillation is done by evacuated tubes. Reflector is used to increase the temperature of evacuated tube. Most of the previous research works have been focusing on single basin solar still, flat plate collector and concentrating collector. In this project various temperatures are measured by using different conditions are single basin solar still with evacuated tubes, double basin solar still, double basin solar still with evacuated tubes and reflector. The output of double basin solar still is greater than single basin solar still. This technique is definitely useful for domestic purpose. People who are living in remote areas can use this technique for drinking purpose.
