An analysis of an inverted absorber double-effect solar still is prese
nted. Energy balance equations have been written, and analytical expre
ssions for water and condensing cover temperatures and the hourly yiel
d have been derived. Numerical computations have been carried out for
a typical day in Delhi. The results thus obtained have been compared w
ith 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.
