Abstract
Solar still is a simple equipment for the fresh water production in the regions where water is scarce and is rich in solar energy sources. In this paper, a solar still unit was built and tested in the south of China to investigate its water production. The test results show that the fresh water production is affected by average solar irradiation intensity, the production of the unit averaged at 6.27 kg/day, the water production decreased to 1.9 kg/day when the daily average solar radiation decreased to 236 W/m2. At the same time, the test result show that because of the difference between the ambient and seawater temperatures, the solar still could produce water at night, and the daily production could increase to 7.55 kg/day when the daily average solar radiation is 533 W/m2.
