The effect on the efficiency of the photovoltaic panel used for the charging of mobile phones of the solar radiation in Elazig, Turkey

In this study, mobile phone charge analysis was performed with portable solar panel in changing irradiation conditions and the efficiency of photovoltaic panel was determined. In photovoltaic systems, it is necessary to take into account the actual environmental conditions in the installation site to accurately determine the system performance. In this context, the aim of this study is to determine the efficiency of portable photovoltaic panels used to charge mobile phones in real outdoor conditions and to contribute to the use of the system in maximum efficiency. The designed system was tested in Elazig/Turkey province under external atmospheric conditions. Experiments were done in different months and throughout days in 2017. Radiation and outdoor temperatures were measured during the experiments. As a result, it was seen that the actual meteorological values affect the efficiency of the photovoltaic panel and the panel efficiency ranged from 12% to 19% for the Elazig province.
