“…According to Liang et al (2022), the voltage with load tends to be proportional to the incident radiation, which justifies the similar behavior of the voltage values to the radiation curves. The fact that the PVT/w systems presented lower values of voltage with load than the PV system in the tests together demonstrates that the cell temperature significantly influenced the output values, as observed by Khodadadi & Sheikholeslami (2022). For this reason, the PVT/w_SB system, with the highest temperature among the systems, presented the lowest values of voltage with load, reaching its peak value before the other systems (10:55 am against 11:24 am for the PVT/w_CB).…”

This study evaluated the electrical performance of a photovoltaic-thermal (PVT) system using water as a cooling fluid (PVT/w), with adaptation, in a photovoltaic module of a device for heating water without direct contact with the cell and with air as the secondary working fluid. The PVT/w system with forced and natural circulation was compared in a regime of thermal accumulation of hot water and supply by a boiler reservoir relative to the same PV panel with the original factory characteristics. The average system temperature, open circuit voltage, current and voltage with load, and generated electric power were analyzed during seven non-consecutive days, with ten repetitions every thirty minutes between 9:30 am and 2:00 pm in the city of Dourados-MS, Brazil, between June and July 2021. The PVT system with forced circulation (PVT/w_CB) presented the best electrical performance compared to the PVT system with natural circulation (PVT/w_SB), in the order of 3.7%.

China’s building energy consumption is growing and the energy consumption of the whole process of buildings accounts for more than 46.5% of the country’s total energy consumption, of which the proportion of energy consumption used for heating, ventilation and air conditioning is as high as 50%. Solar energy has the greatest potential to achieve energy conservation in buildings. Buildings are the best carrier for solar energy utilization because of the advantages of local collection and local application. The combination of solar energy and buildings can meet a variety of energy and health needs in buildings, among which solar photovoltaic and CSP building integration technology is an important way to reduce building energy consumption and improve indoor air quality. This article presents a PV/T-based thermal storage wall system that efficiently utilizes solar energy. It outlines the PV/T technology’s fundamental principles and provides a detailed description of the system’s construction and operation, highlighting critical components like the solid thermal storage medium and heat transfer via a heat pump. The analysis indicates improved energy utilization and favorable economic feasibility. This technology offers a practical solution for the construction industry, promoting sustainable energy practices and environmental conservation.

“…A lower operating temperature provides a longer life cycle for a PVT system than a standalone PV system. A higher initial cost of PVT systems could be compensated with a higher efficiency output, leading to a shorter payback period [9]. A comprehensive literature analysis was conducted, and the terms used by researchers to evaluate the PVT system's economic aspects are detailed below.…”

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.
