Assessment and analysis on numerical and experimental performance of the photovoltaic systems for Germany and Turkey

Solar energy plants are popular due to their low cost, and environmental friendly and renewable nature. Germany is the leading country in the solar energy market in the world. Turkey also possesses a very high potential in terms of solar energy among European countries. The present study aims to draw attention to solar energy plants and define its applicability for these two countries. Two identical photovoltaic systems, installed in Turkey and Germany, were analyzed. First, we introduced the experimental results of two installed photovoltaic systems. Second, we numerically modelled two photovoltaic systems and processed the data with PVsyst in order to compare and verify experimental results. Numerical results display a good agreement with the experimental results, indicating that the performance of the modelling system is high, and that it can be used as a tentative photovoltaic system prior to installation. In addition, the solar energy capacities of Turkey and Germany are analyzed and discussed in detail.
