Abstract: Water is essential to life. The origin and continuation of mankind is based on water. The supply of drinking water is an
important problem for the developing countries. The wooden box has a thickness of 8mm. It consists of a top cover of
transparent glass with a tilt of 18°, 26° and is coated with black paint to absorb the maximum possible solar energy. The yield of
the single basin solar still is very less and it increases considerably when the solar still was built with copper sheet. An analysis of
single slope solar still has done on different tilt angle to optimizing study of tilt angle. They greatly improve the rate of
