Abstract
Conventional solar still owns poor efficiency and low distillate output, hence not found commercially popular for domestic and industrial applications. The present work demonstrates the improved design of solar still with stepped-corrugated absorber plate for higher energy efficiency and yield. During experimentation, the productivity of stepped-corrugated and conventional solar still is found as 2.50 kg/m2 per day and 0.90 kg/m2 per day, respectively. The energy efficiency of stepped-corrugated and conventional solar still is found as 33.33 and 18.67%, respectively. From this exertion, it is concluded that the stepped-corrugated still has better yield and efficiency as compared to the conventional still.
