Enhancement of distillate output of solar still by cooling glass cover

The difference in temperature between the of basin water and glass cover is most important regulating factor for getting yield from a solar still. higher differential, more distillate still produces. This can be enhanced either by increasing decreasing or combining both strategies together. A strategy lowering to cool it with air flowing water. Cooling not only boosts production but also cleans it. presence dust particles on reduces amount energy impacting basin, which continuously cleaned over In present work detailed review various methods used have been discussed. decrease up 20oC cooling maximum increase efficiency about 20%.
