摘要:Solar desalination is becoming more reliable and common especially in developing countries where receive sufficient sunshine throughout the year. In addition, solar still devices are considered as one of the cheapest and simplest desalination methods depends on solar energy, but suffer from low productivity. This work presents an experimental analysis of the performance and productivity of novel cascade solar still with a modified absorber plate with additional baffles on the slope surfaces as a new attempt to enhance the productivity of solar stills. The solar intensity was taken as input and the productivity as output are considered for evaluating the solar still in order to examine the effect of the modified absorber plate on the performance and productivity of novel cascade solar still.
