“…As shown in Figure 2A by comparing the electrical power predicted by the theoretical model of the photovoltaic‐thermal module with experimental results reported by Abdul‐Ganiyu et al, 55 it was found that the tolerances are within ±3.5%. Figure 2B makes a comparison between the results of the hot water temperature of the current model and the work by Hassan et al 56 for the solar dish concentrator with the solar thermal receiver; it was found that the tolerances are within ±4.9%. Also, by comparing the yield of pure water predicted by the model of the HDH unit with experimental results reported by Nada et al, 57 it was found that the tolerances are within ±4.7%.…”

The lack of pure water and electricity in remote regions pushes to simulate of an innovative high-productive hybrid desalination system with the lowest power consumption rates, and this represents a major challenge recently. To achieve this goal, the present study aimed to simulate an innovative hybrid HDH-RO desalination system powered by photovoltaic-thermal modules and a solar dish concentrator. The proposed innovative hybrid system is characterized by integrating two common technologies for pure water production namely: HDH desalination unit and RO desalination unit with an energy recovery device. In order to achieve the highest production rates of pure water with the lowest possible rates of power consumption, the proposed innovative hybrid system was provided with photovoltaic-thermal modules and solar dish concentrators, as preheating units to heat the feed water before its entering the HDH-RO desalination unit. The photovoltaic-thermal modules have a dual function: enhancing the performance of photoelectric conversion, and simultaneously preheating the feed water before it enters the spiral coil of the solar dish concentrator. The solar dish concentrator with a solar thermal receiver was purposed to raise the feed water temperatures before it enters the HDH-RO desalination unit, to improve evaporation rates within the HDH unit as well as increase the rates of water permeating for the RO unit. The results indicated that the utilization of the photovoltaic-thermal modules and solar dish concentrators, as preheating units to heat the feed water before its entering the HDH-RO desalination unit has positive effects in terms of increasing the pure water productivity and reducing the rates of power consumption. The productivity of pure water for the innovative hybrid system ranged between 793 and 861 kg/h, with an improvement of 25.

The innovation in concentrated solar power (CSP) systems is one of the many vital solutions to meet the ever-increasing global energy demands. Among various CSP systems, point focus solar concentrators can attain a higher concentration ratio and helps reduce the size of the receiver, resulting in higher operating temperatures, lower thermal losses, and higher system exergy. This article presents a review on a particular class of CSP systems known as stationary point focus solar concentrators, that is, point focus solar concentrators having a stationary receiver. They can be categorized as (a) Scheffler reflector, (b) Scheffler-type concentrator, (c) high temperature concentrator, (d) central tower receiver, and (e) CNRS solar furnace. Having a stationary receiver helps reduce the maintenance and simplifies the plumbing network for heat transfer fluid. However, low maintenance might be a tradeoff on the performance side. This review systematically collates the literature on stationary point focus solar concentrators. Also, the basics of solar angles and various solar tracking systems applicable to this class of CSP systems are covered.
