Even though earth possesses a considerable amount of water (approximately 1.4 billion km³), only a fraction of 1% is freshwater resource for industrial, drinking and agricultural purposes. This reveals the need for effective water management and desalination technologies such as solar stills. In the recent years there has been increasing interest in solar stills, mainly due to their relatively simple, inexpensive and effective operation with desired properties in remote and arid locations. The efficiency of solar stills depends on several factors including solar radiation availability, environmental conditions (air temperature, wind speed, humidity), design or operational variables (surface tension, shape and style of top cover, water depth, condensing cover material), deployment of improvements, and effectiveness of the condensing process. Recent literature indicates that by utilizing nanofluids in solar distillation a considerable opportunity exists to improve the performance and efficiency of solar desalination systems. The emphasis in this review is on studying these parameters and their impact on the efficiency of the Solar Still.
