Asymmetrical solar still with various basin materials

摘要

A solar still is efficient and attractive application of renewable energy (solar) in the distillate production. In this work, the solar still with different basin materials viz; plastic, glass, and galvanized iron (GI) with basin area of 1m × 1m and slope of 13° were fabricated and tested in Anna University, Chennai. The basin materials are taken according to the low cost that is easily available in the local areas. The bottom and side losses of the still are considerably reduced, due to the low cost insulation material (thermcol) beneath the basin liner. The stills are experimentally investigated on a clear day (03/04/2014). Comparison of the various basin materials under the same weather conditions is done. A model economic analysis calculation for the asymmetrical single-basin and single-slope solar still is verified.
