Thar desert of Rajasthan is one of the most water-stressed states in India and has limited surface water
resources, and available groundwater is brackish water; therefore, it must be distillate or purified. In the
present paper, we develop a concentrating solar thermal desalination device. This system was assembled
by dish concentrator, vessel, SS-based condensing unit, stand and jar for distillate water. Also, paraffin
wax of melting temperature 58–60 C was used in this study as a phase change material to increase
the water temperature and heat the water. A year-round performance analysis was carried out during
2020 at ICAR-Central Arid Zone Research Institute, Jodhpur, India. The maximum productivity with
PCM is 7.12 lit day 1, and without PCM is 6.52 lit day 1 during May 2020. The monthly average distillate
obtained from the PCM-based desalination unit is 4.51 lit.month 1, and without PCM, the distillate yield
is 3.84 lit.month 1.Incorporating paraffin as a PCM to the concentrating desalination system increased
system working hours and increased system productivity by about 109%. The maximum average daily
efficiency of the parabolic concentrating solar thermal desalination device varied from 13.5 percent in
January to 34.8 percent in May. The economic analysis of the concentrating solar thermal desalination
device revealed that the high value of the internal rate of return IRR (87.2 percent) and low value of
the payback period (1.40 Years) makes the unit very cost-efficient. Therefore, this solar desalination
device can be successfully used to desalinate the saline water in rural areas of the Thar desert of
Rajasthan to meet the requirement of potable water. This present study contains valuable information,
particularly for researchers, industrialists, and investors interested in solar-based water desalination system
investment in hot arid areas of India.
