Abstract
The Algeria Sahara sufers from the scarcity of drinking water. Solar distillation is one of the simplest and generally inexpensive techniques to solve this problem. However, a second problem arises; this is low productivity in winter. The objective of
this study is to overcome this difculty by modifying the experimental setup by adding nanoparticles that compensate for the
weak solar radiation in winter. The experimental results show that the daily productivity of conventional solar still in summer
is 3.5 kg m−2 and in winter is 2.2 kg m−2. Similarly conventional solar still with CuO nanoparticles in winter is 3 kg/m2
per
day. The productivity of the conventional solar still without CuO nanoparticles in summer is best as compared to others. When
comparing productivity during the winter season, it is found that the productivity of the modifed distillery was 1.4 times better
than the productivity of the unmodifed distillery. The daily exergy efciency of the conventional solar still in summer and
winter is equal to 1.2 and 1.58%, respectively. The use of CuO nanoparticles in winter season has exergy efciency equal to
2.41%. The daily exergy efciency of the solar still was increased by 52.5% when using CuO nanoparticles in the winter season
