Energy analysis of the performance of a hybrid solar still composed of a parabolic concentrator with PV generator

Abstract

In this study, a hybrid system with the addition of a greenhouse solar still is proposed to improve the efficiency, performance, and productivity of solar still. The energy analysis is performed with the help of a computer program using a set of typical design and operating parameters. The result showed that the hybrid still coupled with a PCC (parabolic cylindrical concentrator) can produce 110 l/m2 per day. The temperatures of the basin and water of the hybrid still with PCC are 140 and 100 °C, respectively. The causes are the several sources of temperatures are added together in a single system. The obtained values of efficiency, production, and performance are 160%, 100 l/m2, and 2, respectively. The results show also that the temperature and production in the month of January are 70 °C and 50 l/m2 per day, respectively, despite the negative influence of meteorological parameters. The performance of the suggested hybrid still is found to be higher than that of the single still without a concentrator.

Comparative Study of Hemispherical Solar Still Using Different Novel Basin Materials With and Without Internal Reflector: Yield, Energy, Exergy, Water Quality and Cost Analysis

“…This leads to reduce the solar radiation absorption and decreases its e ciency (Taheri and Zahedi 2020). To get a solution to the above-mentioned drawbacks of the SS and enhances the SS productivity, many researchers are suggested several unconventional designs like regenerative (Sakthivel et al 2010), air bubbled (Pandey 1984), stepped (Omara et al 2014), wick (Minasian, A. and Al-Karaghouli 1994), V-type , thermoelectric (Rahbar and Esfahani 2012), masonic (Navale et al 2016), tubular (Rahbar et al 2015), pyramid (Al-Madhhachi and Smaisim 2021), trays (Essa et al 2021), hybrid (Mandi et al 2021) and hemispherical (Ismail 2009) SS. In the latter design of SS, the cover has a hemispherical shape in order to increase the amount of the solar energy collected by the SS by reducing the shadow of still walls.…”
