Herein, a combination of a multicriteria decision‐making (MCDM) technique and geographic information system (GIS) is established to identify the most appropriate sites for the installation of large‐scale concentrated solar power (CSP) plants in the Marrakech‐Safi region located in mid‐south Morocco. For this purpose, numerous criteria affecting its deployment, such as climate, orography, location, and water resources, are taken into account. As a CSP plant requires cooling for its power block cycle, wet and dry cooling options are explored to assess the suitability of the field of study to host CSP plants with both scenarios. Results reveal that 62.4% of the study area is deemed appropriate for CSP plant hosting. Moreover, 16.1% and 7.6% of the suitable surface area is evaluated as highly suitable for wet and dry cooling systems, respectively. Nevertheless, the excellent areas represent 4.5% for both scenarios.

“…The optical efficiency range obtained was between 40% on December (13:00) and 77% on June (8:00‐16:00). Mouaky et al studied the thermal performance of the 186 kWth PTC under a semi‐arid climate in Morocco concerning the effect of soiling on the energy production of the system. Results revealed that the proposed design can produce 388 Tons of steam at 500 kPa.…”

A wide range of engineering industrial applications require both the thermal and optical efficiencies of the system to be maximized with a reasonable low penalty for the friction factor and subsequently low losses in pressure. Among the family of concentrated solar power systems, parabolic trough collectors (PTCs), which have recently received significant attention, face similar challenges. The current work presents an extensive review of the PTC systems comparing recent and past technologies, which are widely being used to improve and enhance the thermal and optical efficiencies. Furthermore, the techniques used for single and two-phase flow modeling in numerical simulations, design variables, and experimental processes have been discussed in detail. The article also presents different numerical methods and analytical approaches of implementing the nonuniform solar distribution with different design parameters. Four main technologies are comprehensively addressed to effectively enhance the thermal performance of the PTCs; changing working heat transfer fluids, replacing the working fluids by nanofluids (single and hybrid) that have higher thermal-physical properties than those of base working fluids, inserting different tabulators with various design configurations, and finally combining the advantages of nanofluids and swirl generators in the same application. The article also critically summarizes the studies investigating the enhancement of thermal performance: use of novel design of PTCs and passive heat transfer enhancement techniques. Finally, a wide range of numerical and experimental studies are proposed for the future work related to the aforementioned main technologies.
