An attempt to solar still productivity optimization; solar still shape, glass cover inclination and inner surface area of a single basin solar still, optimization

الملخص EN

Solar energy utilization in five different shapes of solar stills is considered.

Also, four solar still with similar specification but different in inclination angle, and another four with similar specification but different in inner surface areas have been investigated in an attempt to optimize solar still productivity.

It is found that the best solar still is that which has symmetric double slope, the best inclination angle is 45P P and that the lesser inner surface area (11645 c give the best productivity).
