An analysis of an inverted absorber double-effect solar still is presented. Energy balance equations have been written, and analytical expressions for water and condensing cover temperatures and the hourly yield have been
derived. Numerical computations have been carried out for a typical day in Delhi. The results thus obtained have been compared with those of the conventional double effect (double basin) solar still. It was observed that an inverted absorber solar still gives a higher output than the conventional double-effect one.
