Abstract
The present research involved exergy analysis of a passive solar distillation unit. A developed unit of solar distillation of 40 litres of holding capacity was optimized for desired output of 5 litres of distilled water. Performance of the developed unit was observed during 8AM to 5PM. The solar still produced 4.5 litres of freshwater per day per m2. According to the thermal evaluation of the solar still, the maximum daily exergy efficiency was found to be 5.44%.
