SUMMARYIn this paper a new self-sustainable hybrid photovoltaic thermal (PV/T)-integrated-active solar still has been designed and tested for composite climate at I.I.T. New Delhi (28832 0 N; 77812 0 E). The PV system is used to generate electricity to run the pump (60 W and 18 V) as well as thermal energy to heat the water in the collector. The proposed design of hybrid-active solar still can be used at any remote location because of its self-sustainability. The experiments were performed on the set-up for different water depths and for different running duration of the pump. It has been observed that the hybrid-active solar still gives a higher yield (more than 3.5 times) than the passive solar still. It has also been observed that the daily distillate yield and thermal efficiency of the hybrid-active solar still remain almost the same for all water depths in the basin by reducing the daily running period of the pump from 9 to 5 h. This running period of the pump reduced saves 43% of the power used to run the pump with 9 h running, without affecting the performance of the solar still. This work also deals with exergy analysis of the system.

“…evaluated the performance of evacuated tubular collector integrated solar still system (EISS) under forced mode. Tiwari et al [68] modeled and evaluated the thermal performance of different active solar still integrated with FPC, concentrating collector (CC), and ETC with and without heat pipe. However, the investment cost of the EISS was about 3.5 times than single slope solar still.…”

Energy crisis and water born diseases caused by impure water are two major concerns of the present era. Various techniques have been used to make saline/brackish water potable. Filtration, precipitation, sterilization, chemical treatment, etc. are some processes that remove macro impurities from impure water. Distillation is thermal energy‐based process that effectively removes contaminants from impure water. Reverse osmosis is a membrane‐based technique widely used for the purification purposes. Electrodialysis, Ion‐exchange, and Freezing are some other processes used to get soft/distilled water for various commercial and domestic uses. Most of the desalination techniques utilize energy from the nonrenewable energy sources. Solar distillation is one of the solutions of getting potable water using solar energy. Solar distillation unit coupled with thermal collectors, photovoltaic panels, and concentrators makes the system active and increases the distillate three to six times than conventional units. Multistage, multieffect active solar still is observed to give an average distillate output of 20 kg/m2/d. Economic analysis also shows that active solar still is a good replacement of nonrenewable energy based water purification techniques. In this article, different water desalination techniques with their economic analysis are briefly discussed. Detailed comprehensive review of researches carried out on active solar still system considering their designs, performance parameters, different hybrid combinations, along with challenges, opportunities, future scope of improvements have also been highlighted. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 444–464, 2018

“…Kumar and Tiwari (1998) have optimized the number of collectors and basin area for higher yield for a given depth of active solar still. Tiwari et al (2007) have studied the comparative performance evaluation of an active solar distillation system and evaluated the theoretical yield from solar stills coupled with flat plate collector, concentrating collector, evacuated tube collector, and evacuated tube collector with heat pipe.…”

In this article, thermal modeling of a single basin solar still coupled with an evacuated tube solar collector under natural circulation mode has been carried out on the basis energy balance equations. The expressions of inner surface of glass cover, outer surface of glass cover, basin liner, and water mass have been derived for the numerical computation. The experiments were conducted under various meteorological conditions for 0.05 m water depth. This experimental setup has been installed at Solar Energy Park, Tamilnadu College of Engineering, Coimbatore, India (Latitude: 11 ı N; Longitude: 77 ı E; and an altitude of 409 m above sea level). Observation revealed that there was a considerable increase in the average daily yield of solar still when integrated with an evacuated tube solar collector. For all the cases, the correlation of coefficients (r) between theoretical and experimental values have been verified and they showed good agreement with 0:98 < r < 0:99 and root mean square present deviation of 10:26 < e < 39:7%.
