Desalination by solar radiation is one of the efficient ways to filter sea water and regarding the renewable solar radiation energy application as a way to provide sweet water is regarded in line with sustainable development and adaptable to environment. Condensation irrigation system is a developed modern idea which takes into consideration environmental issues together with application of sea water. This system is being used for providing drinking water and plantation. The major part of this system that is responsible for providing sweet water is solar still. Solar stills utilize solar radiation for sea water desalination. In the present research, the effect of atmospheric factors and solar still base surface parameter on the evaporation potentiality in solar stills has been investigated in a one-year statistic period that purpose of this study, is trying to determine and recommend using stills with high evaporation potential. Results of this study indicate high dependency degree of stills evaporation potential to atmospheric factors that the intensity dependency of this parameter is including: positive relationship of ambient air temperature (R=0.95), the positive relationship of the number of sunshine hours per day (R=0.73) and negatively relationship relative humidity (R=-0.72). These observations also showed that by reducing the solar stills surface, evaporation potentiality in solar stills will increase and Investigate the effect of solar still base surface by ANOVA results indicated significant differences at the one percent level between evaporation from Solar Stills.
