The power from sun caught by earth is nearby 1.8 × 1011MW which is obtained by utilizing sun’s energy by photovoltaic cells appears to be a good substitute then the conventional fuels. The efficiency of the system declines due to the heat confined in photovoltaic cells throughout the operation [1]. Enhancing the efficiency of Sun power generation by engaging nanofluids in PV/T systems is achieved by recent improvement in the nanotechnology field. In our work Nano fluids are employed as coolants to lower the PV panel temperatures and thus the system efficiency increases. This study comprehensively analyses the effectiveness of Zinc nanoparticles in different base fluids i.e. water, water (75%) & ethylene glycol (25%) and water (75%) & propylene glycol (25%) to enhance the electrical and thermal efficiency of the PV/T system. Other parameters like flow rate, concentration of nanoparticles by volume and sonication time are kept constant throughout the experiment. The experiments were performed on an indoor setup and to replicate the solar irradiance a solar simulator was engaged as per previous year’s metrological data. It is perceived that the extreme change in electrical efficiency is 2.6% and maximum change in thermal efficiency observed is 31% as compared to conventional system. |
