Abstract

In this study, the techno-economic assessment of a Grid-Connected Photovoltaic Thermal (GCPVT) system with nanofluid as base fluid is carried out. The investigation blinds both theoretical and experimental work. The reason why a grid-connected PV is considered is due to grid-connected PV configurations constituting about 86% of the PV tsystem, with 54% of them being centralised while 32% are being distributed, which shows the importance of such systems and the potential they can achieve with PV/T collectors. The study focuses on the electrical and thermal performance of PV/T. The yield and capacity factors are used to investigate the productivity and utilisation of the PV panel, respectively. In addition, the assessment of the cost analysis and economic aspect was conducted through Cost of Energy (CoE) and Payback Period (PBP) calculations. This system was installed, tested, and data has been collected in the green innovation and technology park in UKM, Bangi. Furthermore, an evaluation of the panel production in terms of current, voltage, power and efficiency is presented. The average daily ambient temperature and total global solar energy in Bangi are 38.89 °C and 4062 Wh/m2, respectively. A MATLAB software code is developed and used for the data analysis. The results of the assessment show that the GCPVT system has an annual yield factor and capacity factor of (128.34–183.75) kWh/kWp and (17.82–25.52)%, respectively. While the cost of energy, payback period, and efficiency are 0.196 USD/kWh, 7–8 years and 14.25%, respectively. Moreover, different nanoparticle mass fractions in the nanofluid were considered and the optimum fraction was found to be 3%. Additionally, different comparisons of this system with other systems and countries are presented to show its improvement and cost-effectiveness. This study indicates how the GCPVT system with nanofluid improved the PV technical and economic performance.
