Abstract

In this article, designed and fabricated the photovoltaic thermal collector (PVT) using nano particle nanofluid. The purpose of this study is to look into the impact of using water and water-based graphene nanoplatelets at a concentration of 0.05 wt percent on the performance of PVT systems. Outdoor tests were carried out at volume flow rates of 0.5 L/min and 1.0 L/min for the aforementioned nanofluids, respectively, using water as a reference fluid. The study results, which were analysed from an energetic standpoint, demonstrated and revealed that graphene water nanofluid performed better in terms of photovoltaic energetic conversion than water, which can generate the highest thermal efficiency during the peak period of solar radiation and high cell temperature. The inclusion of water in the PVT collector increases average daily electrical efficiency by 7.8 percent and 8.5 percent, respectively, at flow rates of 0.5 LPM and 1.0 LPM. Furthermore, using water in the PVT collector increases average daily thermal efficiency by 24.9 percent and 26.3 percent, respectively, at flow rates of 0.5 LPM and 1.0 LPM.
