Experimental investigation of photovoltaic panel surface temperature at various tilt angles

Abstract

By growing the population of the world, the demand for clean and renewable energy resources is increasing, because fossil energy sources available are limited. Solar energy is a sustainable energy source which is widely accessible. Photovoltaic systems are utilized to generate electrical energy from solar radiation. Photovoltaic panel temperature is a major parameter that influence its effectiveness. Decreasing photovoltaic temperature could be rise its performance. In this work, Photovoltaic panel surface temperature has been measured at various tilt angles. This data research consists of time-depending photovoltaic module and tedlar temperature values with climatic characteristics of the test region. In the experimental section, photovoltaic panel were placed at 30°, 32° and 34° tilt angles. Temperature values were obtained from the front glass and tedlar foil. The main goal of this study is investigating the influence of tilt angle on photovoltaic temperature which could be used in numerical works such CFD simulation.
