Adhikari et al. (1995) reported that solar
distillation is one of the important and technically viable
applications of solar energy. A considerable amount of work
has been done for studying the basin-type solar stills. The
prototype design of such solar stills consists of a blackened
water basin having a sloped transparent cover, which
permits incident solar radiation to pass through it and get.
Absorbed by the basin. water gets heated and the water
vapors formed condense over the underside of the cover to
form droplets which are collected in a trough as distilled
water. Also, they reported that a computer simulation model
is presented for studying the steady-state performance of a
multi-stage stacked tray solar still
