Abstract :
A single slope solar still with the basin area of 60 cm x 80 cm and slope of 110 was fabricated and tested in
Pondicherry. The inner wall is coated with black paint in order to improve the heat transfer rate. The bottom and side
losses of the still are considerably reduced, due to the porous material beneath the basin liner. Effect of solar pond
coupled with the still are experimentally investigated on a clear, low radiation and high radiation and found that clear
day has the maximum productivity. A model economic analysis calculation for single basin solar still coupled with
pond is also done and the results are reported in this paper.
