Double slope solar still distillate output data set for conventional still and still with or without reflectors and PCM using high TDS water samples

The rate of distillate and temperatures are important factors for analyzing the solar stills. The higher rate of distillate and hence the higher efficiency can be achieved by engrossing different measures to develop the still, for example; double slope instead of single slope, incorporating reflectors for maximum insolation, use of PCM for increasing the time period of operation of solar still after sun hours. The data associated with developed double slope solar still is presented to correlate variation of distillate output with the still basin and glass cover temperatures as well as stills with and without reflectors and PCM for different types of high TDS level water samples. The data set of temperature and distillate output can be used to analyze the working of stills for its efficiency and effectiveness in terms of distillate yield. (C) 2019 The Author.
