“…The partial-load operation increased the irreversibility of the cycles, and this effect was more pronounced with load reduction. Increasing the condenser backpressure decreased exergy efficiency [8]- [10]. Successive withdrawals from high-pressure heaters indicate a gradual increase in exergy efficiency for the control volume, excluding boilers, while decreasing exergy efficiency when the entire plant, including boilers, was considered [11]- [13].…”

In this study, an analysis was conducted on a steam power plant system with a capacity of 2 x 7 MW based on coal. The coal fuel used by the majority of refined sizes is not in accordance with the recommendations of the American Society of Mechanical Engineers (ASME). The main objective of the study was to analyze the system components separately and to measure the exergy value of the components, covering the electrical energy so that it is known which equipment experiences the greatest energy loss as well as knowing the efficiency value of the equipment used. Efficiency and exergy are calculated using plant operation data. The results of the study found that the largest exergy destruction occurred in boilers, meaning that there was the largest energy loss in this section with a value of 37.34 MW (16.71%), while the destruction of the smallest exergy occurred in condensers of 0.58 MW (99.24%).

“…Among them, photovoltaic (PV) systems, which are easy to install and have simple structures, are the most widely used. However, PV systems have a low solar energy conversion efficiency of approximately 10-20% and suffer from a decrease in power generation efficiency as the temperature of the solar cells increases [1,2].…”

An air-based photovoltaic thermal collector (PVTC) is a system that generates both electricity and heat using air flowing over a photovoltaic (PV) module. This system offers the advantage of easy maintenance; however, it suffers from lower thermal efficiency compared to other PVTCs, mostly owing to the low heat capacity of air. Thus, this study introduces a novel PVTC incorporating dual ducts and semicircular turbulators, which were experimentally evaluated under actual weather conditions in the Republic of Korea. The proposed PVTC was compared with two other types of PVTC: one is a single-duct PVTC with semicircular turbulators, and the other is a dual-duct PVTC without turbulators. The results showed that the thermal efficiency of the proposed PVTC increased by approximately 88.7% compared to the single-duct PVTC with a turbulator and by 9.3% compared to the dual-duct PVTC without a turbulator. The electrical efficiency showed a slight decrease of about 7.2% compared to the single-duct PVTC but an increase of 1.4% compared to the dual-duct PVTC without a turbulator. Overall, the total efficiency of the proposed PVTC increased by 54.2% and 7.7% compared to the single-duct PVTC and the dual-duct PVTC without a turbulator, respectively. These experimental results demonstrate that attaching dual ducts and semicircular turbulators to an existing PVTC increases the daily thermal energy output, which ultimately enhances the total daily energy output.

“…PVT systems are found to be one of the superior candidate in energy systems [6]. The review paper [6] discussed recent experimental and numerical works containing PVT systems with PCM modules (new technologies and material selections). To improve the PVT system's total energy efficiency, it is advised to use different interior tube configurations (such as micro-channel, wave tape, twisted tape, etc) and PCMs (nano enhanced PCM, nanofluid and composite PCM).…”

Solar energy is the most prospective renewable resource that humankind has access to, for acquiring the most usable energy. Photovoltaic thermal systems (PVT) are deemed to be one among the most efficient methods for capturing solar energy because of their distinct ability to produce electrical power by photovoltaic conversion while simultaneously dissipating the heat generated in the process. The necessity of financial investment is a major stumbling block in putting this strategy into action in actual application. This paper delivers updated literature on the economic aspects of PVT-Phase change materials (PCM) systems (installation, operation, and maintenance) that several researchers had carried out. Payback time is taken into account while calculating the profitability of PVT systems. Finally, the performances of several PVT-PCM systems were compared, and the economic analysis confirmed that the PVT system is financially viable. PVT system holds tremendous potential to be incorporated in residential/commercial buildings. The PVT system is a promising technology that still needs refinement in terms of overall efficiency and environmental factors, according to the available literature assessments.
