Abstract

The potential for solar water distillation in Malawi has been modelled. Mean monthly global solar radiation (H) data from 19 sites spread all over the country was used to compute the mean monthly daily distillate productivity (M). Results show that H varies from 15.3 MJ m*-2 to 27.8 MJ m*-2 while M varies from 1.0 kg m*-2 to 2.5 kg m*-2. Distillate productivity is high (up to 2.5 kg m*-2) during the dry season, in phase with the shortage of water supply. It appears that there is enormous potential for harnessing solar radiation to improve the quality of drinking water in the country.
