Double slope solar stills are reported to give lower yields in winter season. In this work an attempt has been made to improve the performance of still with double slope in winter. A comparative experimental and theoretical analysis of conventional and modified single basin still with double slope augmented with black dye, pebbles and iron chips (5 kg each) is reported in this manuscript. The experiments are carried out in the month of November and December in 2017 at meteorological conditions of Jaypee University of Engineering and Technology, Guna (Latitude: 24°39'N, Longitude: 77°19'E). Distillate yield in a modified solar still due to the augmentation has improved by 28.4% as compared with conventional solar still at a common water depth of 0.025 m, whereas its overall heat transfer coefficient and overall thermal efficiency are improved by 55.7 and 25.01%, respectively.

Experimental and theoretical analysis of the three single basin double slope solar stills with 15 ̊, 30 ̊ and 45 ̊ glass cover inclinations, are carried out at meteorological conditions of Raghogarh, Guna (Latitude: 24°39'N, Longitude: 77°19'E, India). The experiments are performed from 14th to 16th June 2017. Detailed energy and exergy analysis are carried out using theoretical model proposed by Kumar & Tiwari, based on regression analysis. It has been observed that the theoretical results obtained from evaluation have good agreement with the experimental results. Maximum fresh water is obtained from 15 ̊ inclined glass cover solar still (viz.4.66 litre of 14 h observation ) and contribution of 52% and 48% from east and west side of solar still respectively. At 15:00 h all the stills show maximum thermal efficiency viz. 23.69, 29.24 and 25.09% for 15 ̊, 30 ̊ and 45 ̊ cover inclinations respectively. It has been observed that maximum exergy is lost in basin followed by glass and water in all the double slope solar stills.
