Abstract: A solar distillation apparatus is provided which employs at least one pan which is adapted to contain a distilland therein and which has its upper portion heated directly by solar radiant energy passing through a transparent cover disposed above the pan and has its lower portion at least partially heated by radiant energy reflected from a reflective inside surface comprising a bottom wall of the apparatus such that simultaneous heating of both the upper and lower portions of the distilland is achieved and results in a more efficient heating and the provision of vapors from such distilland which engage the bottom surface of the cover and condense thereon to define a distillant which because the apparatus and cover are disposed at an angle to a horizontal plane move under the influence of gravity along such bottom surface into a reservoir therefor.
