“…Additionally, he proposes a model for a PTC collector coupled to SRC-PVT that includes case studies and economic and environmental analysis [25]. Finally, a parametric study of the proposed model is presented [26]. The exclusion of economic and environmental contributions is justified by the need to prioritize the information according to theoretical and experimental contributions, which are more related to the development of mathematical models, test prototypes and validation (which is the objective of this review paper).…”

“…There are studies that analyze the SRC-PVT using their own thermal resistance models. For example, Herez et al [26] discuss a triangular geometry SRC-PVT model and consider the PV to be in direct contact with the environment. In contrast, Karathanassis et al [45] present a model of a rectangular-geometry SRC-PVT with seven different layers.…”

This paper is a summary of the last ten years of work on the study of parabolic trough collectors (PTCs) and compound parabolic collectors (CPCs) coupled to photovoltaic and thermal solar receiver collectors (SCR-PVTs). While reviewing the state of the art, numerous review papers were found that focused on conventional solar receiver collector (SRC) technology for solar thermal generation. However, there is a lack of review papers summarizing SRC-PVT hybrid technology for solar electric/thermal generation, which would be beneficial for researchers interested in this area of research. This paper provides a review of SRC-PVT hybrid technologies. The theoretical foundations for analyzing and modeling PTC and CPC concentrators coupled to SRC-PVT are described, with an emphasis on modeling through thermal resistances and energy balances. Additionally, this section provides a concise overview of previous studies that have addressed the modeling of PTC and CPC collectors coupled to SCR-PVT, as well as experimental information useful for the validation of new mathematical models of SRC-PVT.

“…The authors found that the system's thermal efficiency decreased as the Reynolds number increased, and the thickness of the absorber did not affect the electrical and thermal behavior of the system. 20 The MCM in combination with the finite volume method was used in a comparison study of four optical models of a PTC system. The configuration with optimal performance was selected based on the simulation results.…”

Summary This work presents an experimental evaluation of a new design of a parabolic trough solar collector (PTC). To maximize the energy yield, a solar tracking system is implemented. The thermal performance of the PTC at three outdoor test methods is evaluated. The new design essentially affects the balloon, the trunk, the insulation, the inner reflector, the glass, the upper plane reflector, and the cover. The system performance with bi‐axial orientation and an absorber with a glass‐covered envelope is compared with two other designs of mono‐ and bi‐axial orientation without a glass‐covered envelope. The tests of the PTC with an aperture area of 2.88 m2 were conducted in Tunisian weather conditions, and the results are compared with similar systems already published data in the literature. A dynamic simulation with TRNSYS software is developed to evaluate the system performance based on experimental results. An economic study to evaluate the system's feasibility is conducted. The results showed that the new design achieved a maximum temperature of 179°C in comparison to 134 and 120°C for the mono‐ and bi‐axial orientation without a glass‐covered envelope, respectively. Furthermore, in the new PTC design, the useful daily energy gain increased by 33% and 15%, and the system thermal efficiency increased by 8.9% and 5.8% in summer and winter, respectively, in comparison to the case of mono‐axial orientation without a glass envelope. Besides, the maximum useful energy gain and the instantaneous thermal efficiency in the new design were 22.6 MJ and 73.45%, respectively, in comparison to 17.93 MJ and 67.41% for the mono‐axial orientation without a glass‐covered envelope. The gross payback period of the system was found to be 3.3 years with an NPV of €5257 over the lifetime of the system.
