1. A solar still for producing fresh water, including
a solar panel cell (30);
a water evaporation chamber (36) with a water condenser plate (26) for condensing water vapour;
a water collector (11) to collect condensed water vapour and fluidly connected to a condensed water storage chamber (32);
a feedwater inlet water preheater chamber (31) with a feedwater inlet port fluidly connected to receive feedwater, and fluidly connected to an inlet water feed distributor (7) to distribute feedwater to the water evaporation chamber (36)
a heat exchange chamber (33) to receive water that did not evaporate in the water evaporation chamber (36);
the feedwater inlet water preheater chamber (31) thermally connected to the solar panel cell (30) and at least partially surrounding the condensed water storage chamber (32) and the heat exchange chamber (33).
