The requirement of various methods to improve distillate output of solar still: a review

Solar still is a simple apparatus used to convert available brackish or saline water into potable water by use of solar energy. Distillate output of solar still depends on higher water temperature inside the basin of solar still. Solar still has a fixed area and fixed amount of solar energy intensity entered, hence the water temperature is found lower, and thus, distillate output remains lower. To increase the water temperature, surface area plays an important role, and thus, fins can be integrated with solar still to increase surface area and hence increment in water temperature. Present review paper shows the research works on the attachment of fins in solar still to improve distillate output.
