Abstract. This study investigates the variational effect of climate factors on the productivity of a basin-type solar still during the harmattan season under the tropical savanna climate. The study was extended to examine the influences of selected climatic, operational, and design (COD) parameters on productivity. Additionally, the efficiency of solar still in removing water impurities during harmattan was also investigated. Explorative data and statistical analysis, and laboratory testing methods were used for these investigations. Results show that seasonal effects of harmattan can either increase or lower productivity. The effect of wind speed on productivity was not clearly defined during the harmattan season. Although high irradiation is essential for increased productivity, its effect is modified by other factors. Water temperature is the most significant to productivity amongst selected factors studied via the design of experiment (DOE). Moreover, the effect of harmattan on the water quality produced was not established. The main contribution of this work is the insights generated for both qualitative and quantitative reliability performance of a basin-type solar still under prevailing climate conditions.

Short summary
Drinking water problems are pervasive in developing nations. In the rural areas of these nations, only contaminated water is available. A device that purifies water by distillation can solve this problem; however, the harvest is location-specific. Since climate varies by location, the device was tested under a tropical climate to ascertain the seasonal effect of harmattan on its harvest. Harmattan effects were established. The reliability of the device during harmattan season is now understood.
