Potential for water distillation by using solar energy in Malawi [PDF]

open access: yes, 2008
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).
