An Experimental Study on Simultaneous Use of Metal Fins and Mirror to Improve the Performance of Photovoltaic Panels

The world is inconceivable without an everlasting demand for energy. Nowadays, various kinds of renewable energies, such as solar energy, are developing rapidly, since they have the least negative environmental impacts. Irradiation intensity one most important parameters in photovoltaic (PV) technology, and so integration mirrors with a PV module can improve its performance. Mounting increases radiation but, at same time, raises surface temperature, which turn reduces electrical efficiency. novelty this study keeping cell temperature low despite receiving more by installing 10 aluminum fins on back panel. All tests were experimentally performed hot climate Dezful, Iran. As result, best tilt angle mirror was found 30°, where output power enhanced 3.3% efficiency reduced 0.5% compared conventional case. When added heat sinks, both 11.4% 13.1%, respectively. Moreover, comprehensive discussions energy exergy provided. entropy generation also calculated accordingly, case 30 + fin generates 1.6% less than base one.
