“…Solar energy is an abundant and clean renewable source utilized for lighting, heating, and generating electricity (Chandrasekar and Senthilkumar, 2021). It is generated by photovoltaic (PV) technology and is an important system to transform nonrenewable energy generation into clean energy generation worldwide (David et al, 2021;Rigo et al, 2019), and largescale PV power generation has shown exponential growth in recent years around the world (IRENA 2021; Liang et al, 2021).…”

Electricity trading occurs under different mechanisms in each country, with auctions being one of these mechanisms. Auctions are widely used to determine their remuneration in the scope of clean energy technologies, such as photovoltaics. Added to the auction process’s bureaucracies and uncertainties, the competing photovoltaic project must keep its technical and economic performance maximized. Given this context, this study aimed to contribute to the competitiveness of photovoltaic plant projects in energy auctions through a performance diagnosis model to identify, measure, and analyze factors in the designing process. For this, a systematic literature review was performed to identify the factors that influence the implementation of a photovoltaic plant project; additionally, the fuzzy Delphi method was applied to examine the factors’ importance. An analytic hierarchy process weighted the factors, and the key performance indicators were developed based on the literature and regulation of the electric energy sector. The model was applied in a centralized photovoltaic energy generation project, which presented a performance index of 41.91%, and the sensitivity analysis and prioritization matrix comprised the post-application study of the model. Our model can help planners improve the competitiveness of photovoltaic projects in auctions by observing underperforming indicators.

“…The solar photovoltaic/thermal (PV/T) system is one of the key research focuses of the solar energy utilization field due to its high thermal energy output and comprehensive utilization compared with PV or solar thermal systems alone [1,2]. It was widely used in several industries, like power generation stations [3][4][5], dryers [6,7], building heating [8,9,10], and desalination systems [11][12][13].…”

“…No matter in what field the PV/T system is used, improving its performance is the key and final objective. Many studies have been conducted to investigate the PV/T system performance involving utilizing PCM [14][15][16], using nanofluids [17,18], concentrated application [19,20], and air and water configurations [1,21,22] by various methodologies such as experimental, analytical, numerical, and simulation techniques. Due to the structure and performance improvement of the heat collector having a great influence on the whole PV/T system components' effi-ciency, technologies for this purpose, including the cooling channel design or modifications of the PV/T systems, have been developed substantially.…”

This study presents a theoretical study on the super thin and conductive thermal absorber with built-in corrugated channels on the basis of previous field experiments. The flow and heat transfer characteristics of the corrugated channels are simulated to identify the factors affecting photovoltaic/thermal (PV/T) system efficiency. The influences of the structural parameters such as the corrugation number, the corrugation area, and the flow channel width on the water outlet temperature and heat collection are discussed in order to support the structural optimization design of the hybrid PV/T system. The simulation results were validated to be in good agreement with experimental results. The results indicate that increasing inlet water velocity leads to a decrease in the outlet temperature. It was found that the corrugation area and the flow channel width have impacts on the outlet temperature of the hybrid PV/T collector panel. When the flow channel width of the absorber plate is reduced from 4 mm to 3 mm, the outlet temperature attained is between 298 and 302 K, and the heat collection is in the range of 16.2–51.4 MJ/h. This led to an increase in the amount of heat collected by 18.6%.

“…By 2050, renewable energy is expected to account for roughly 67% of the world's energy consumption. The road plan predicts that by the year 2020, renewable energy sources will account for 58% of electric power generation, 29% of heating, and 13% of transportation [1]. Solar energy is accomplished using a range of devices that use a variety of light energy conversion techniques to be able to produce useful energy harvesting from solar energy conversion [2].…”

The integration of Phase Change Material (PCM) with the Solar Photovoltaic Thermal (PVT) serves as heat storage to enhance the system's performance. Temperature rises have an undesirable effect on efficiency results in a diminishment in the amount of energy produced by the solar panel. Parametric analysis and temperature investigation are involved in improving the performance of the system. The variation of performance will assist in developing an optimized PVT-PCM system. The model is validated by comparison from published journals on the studies related to phase change material implemented in solar PVT. For the variation of mass flow rate, the overall efficiencies achieved by 10 kg/h, 30 kg/h, 50 kg/h and 70 kg/h are 90.82%, 90.54%, 90.48% and 90.46%, respectively. In addition, solar irradiance of 200 W/m2, 450 W/m2 and 800 W/m2 produced 91.17%, 90.82% and 90.33% of overall efficiencies. Increased in flow rate requires stronger pumps which increase the total cost of the system. Therefore, identifying the optimal flow rate might help to achieve an appropriate thermal efficiency while sustaining in low costs. Finally, this paper presented a numerical investigation of PCM acts as promising elements incorporated in the PVT system that has the capability to reduce the temperature of the PVT-PCM system.
