Abstract

Improving the productivity of solar distillers is of great importance because of its 
dependence on solar energy, which is available to all, environmentally friendly, free of pollutants and 
at a low cost. An experimental study of more than one solar distiller at one time was carried out in 
order to find out the effect of changing the shape of the base of the distiller on the amount of fresh 
water produced by the solar distiller. The experiment was conducted in Najaf (32.0107º N, 44.3265º 
E), Iraq. Two forms of the base were used, the square-shaped base solar still (SSS) and the all-new 
pentagonal base solar still (PSS). The results showed that the productivity of the new pentagonal base 
solar distiller is higher than that of the conventional solar distiller. As the rate of increase in daily 
production at a water height of 1 cm for PSS1 increased by 30.952% and 14.285% for PSS2.
