Water is one of the most essential gifts of nature to mankind. Life exists on earth because of water this makes it unique and precious among the other celestial bodies in universe. Two Thirds of earth’s surface consists of water and of which only 1% of water is useful to us.
Solar distillation happens in the air tight vessel called still. Productivity is the main constraint for solar still. The current work investigates the solar distillation using solar energy and flat plate solar water heater when connected to V type solar still manufactured from Fibre reinforced plastic material. The study involves calculating solar still efficiency at different water level from 10 to 80mm for passive mode and active mode at 80 mm water level. Efficiency and results are compared and concluded. It can be concluded from that distillate output collected in case of active mode is more compared to passive mode. It is due to fact that large difference of temperature observed between basin water temperature and inner glass temperature in active mode than in passive mode. In spite of having high output, still efficiency in active mode is lower than passive mode because of thermal energy loss and high operating temperature.
