This paper is aimed to improve the productivity of an existing conventional single slope solar still with modifications. In this study, the conventional solar still is modified by using reflectors, jute cloth and improved glass angle. The modified still productivity and performance are investigated experimentally and compared to that of conventional solar still. The results demonstrated that solar still performance is improved with the 10o glass angle due to better water flow properties and higher solar radiation fall on the still. The results reveal that, with all combined modifications, the water productivity and efficiency of modified solar still increase by 72.18% and 41.51% respectively more than the conventional one. This implies that modified solar still could be adopted for higher water productivity at a lower additional cost.
