“…Another specific scenario would be hybrid solar desalination of water (Voropoulos et al [27]; Tiwari [28]), where the increase of water heating efficiency would contribute to the stability of distilled water output estimating long-term distilled water production. The possibility of use of a TEG in such a system was already mentioned by Dehghan et al [29]. Economic investment in such engineering integration should have a very short recovery time, due to the non-expensive nature of the components, especially in countries with economic support for sustainable energy systems.…”

Summary An experimental model of a solar hybrid system including photovoltaic (PV) module, concentrating Fresnel lens, thermoelectric generator (TEG), and running water heat extracting unit was created and studied. The PV module used was of c‐Si and TEG of Bi2Te3; the Fresnel lens (solar concentrator) and TEG share an optical train, whereas PV module was illuminated separately with non‐concentrated light. Heat extracting unit operated in thermo siphon mode. In climatic conditions of Mexico (Queretaro, 20o of North latitude, summer time), the Fresnel lens accepted 120 W of solar radiation power, and the system generated 7.0 W of electric power and 30 W of thermal one. The discussion is made of the possible characteristics of a hypothetical hybrid system where all its elements share the same optical train. Copyright © 2016 John Wiley & Sons, Ltd.

“…Daily total yield was observed to be 3.8 L/m 2 with flexible packing (helical wires) and 5.8 L/m 2 with harmonic excitation to the system. Dehghan et al [100] theoretically investigated the thermal modeling and exergy analysis of a thermoelectric assisted solar still. Rahbar and Esfahani [98] tested a heat pipe coupled portable thermoelectric solar still ( Figure 18) and found that this combination can increase the productivity of a solar still.…”

“…The above system can be tested for different water height and PCM thickness in the distillation unit for achieving the optimum values. Dehghan et al [100] theoretically investigated the thermal modeling and exergy analysis of a thermoelectric assisted solar still. Daily energy and exergy efficiency of the developed solar still were found to be 19.8% and 0.95%, respectively.…”

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

“…Soliman (1976) suggested the concept of high temperature solar distillation (active solar distillation system). Worldwide, many researchers (Rai and Tiwari, 1983;Lawrence and Tiwari, 1990;Tayeb, 1992;Tiwari et al, 2003;Dubey and Tiwari, 2008;Hamadou and Abdellatif, 2014;Ling et al, 2014;Huang et al, 2015;Sebaii et al, 2015;Feilizadeh et al, 2015;Rahbar et al, 2015;Morad et al, 2015;Nimr and Dahdolan, 2015;Dehghan et al, 2015;Taghvaei et al, 2015;Edalatpour et al, 2016;Tiwari and Sahota, 2017) have theoretically and experimentally studied different active solar distillation systems.…”
