  7. Abstract:
  8. Energy and environmental crises force different countries to consider new clean sources of energy, especially renewable energies. Fortunately, Iran is located on the solar belt and has a great potential to utilize this huge source of clean, sustainable, accessible and cheap energy. One of the applications of the solar energy is desalination of salty and polluted waters. In this regard, the performance of Multiple Active Solar Stills is investigated in this research. To do so, four similar samples of this device with one, two, three and four stages, were constructed on which many experiments were conducted for 24 hours periods. Experiments were conducted in both continuous (several days) and discontinuous (one day) performance for the first time. Also in a novel work the optimum ratio of collector area to basin area was investigated experimentally. These experiments were performed in both indoor and outdoor conditions. The results of data analysis indicated that one square meter of this solar still coupled to a collector with the area of 3.44 m2 can produce 11.56 liters of distilled water during March in Shiraz. If an additional collector is added to the system, the production increases by 11.12 liters, whereas adding a third collector only increases the production by 5.16 liters. Also in some of the experiments, the optimum number of stages was investigated experimentally for the first time. Analysis of the obtained data revealed that in discontinuous operation, the amount of distilled water varies as a second order function with the number of stages, whereas in continuous operation this parameter is a linear function with the slope of 4.9 and y-intercept of 7.7
