Among the active and passive solar still, when portable water requirement if less than 5 litters then
passive solar still is used otherwise active solar still is used. Only the price of active solar still is more compared
with passive solar still. Hence, it is a prime requisite of every researcher is to increase distillate output in passive
solar still. Research states that, when distance between water and ice cover reduces, automatically distillate output
and efficiency is increased due to decrease of losses. Hence, if a plate is set beneath the water level, at that time
distance between the absorber plate and glass cover decrease and speed of travelling of vapor also decrease along
with the saturation pressure of water increase. Here, chequered plates are going to employ, which increased
convective and evaporative heat transfer coefficient by a diamond shape pattern on its surface.
