Productivity enhancement of solar still has been one of the main goals of the researchers. The purpose of this research is to design a water distillation system that can purify water from nearly any source, a system that is relatively cheap, portable, and depends only on renewable solar energy. To improve the performance external condenser was used. In this research work, two design of solar still was compared experimentally, one with external condenser and other without condenser. The effect of adding external condenser to the still is to decrease the heat loss. To improve this the addition of external condenser in simple solar still was definitely a positive in improving the thermal performance of the still by increasing the overall water collection over 24 h. This paper contains the experimental work and comparison.
