Synergistic experimental investigation of the nano-ceramic cover sheet on the PV module performance

Abstract

Due to the accumulation of the heat on surface of the photovoltaic collector as well as the module’s components, the efficiency of photovoltaic (PV) module is influenced by the increase of temperature in particular at high load (high voltage). Therefore, the efficiency and the current output decrease dramatically, and the full performance of the module tends to be zero in these conditions. In the present work, an experimental comparison between a controlled active water-cooling system and nano-ceramic cover sheet system is performed to get the best performance in high load. Water-cooling system is designed to minimize this effect of the high temperature and dust on the photovoltaic module. In addition, the nano-ceramic cover sheet is installed on the module to reduce the infrared permeability. Furthermore, Experiments were performed on the plain module without active cooling or nano-ceramic cover. After the experimental comparison, the results indicated that the controlled active water-cooling system is extremely improve the performance on the contrary the nano-ceramic cover sheet system which reduces the performance.
