Development of a solar radiation prediction model for four geographical directions and angles

In recent years, rapid economic development and improvement of stable living standards in developed and developing countries have increased the need for energy. Conversion of energy from clean and renewable energy is of increasing importance day by day. Potential solar radiation data is an important tool for the design and implementation of solar power plants, which have an important place among renewable energy sources. In particular, using direct measurement data is important compared to predictive data with numerical calculations using some meteorological data. In this study, the amount of solar irradiation coming to different geographical directions and different angular surfaces was measured, covering all the basic parameters effective in the electricity production of photovoltaic (PV), and the obtained data was stored and analyzed. While obtaining these values, four irradiance sensors were placed in the four geographical directions of East, West, North and South and at 0°, 30°, 60° and 90° the data from these irradiance devices were recorded on a minute basis. As a result of the analysis and inferences made with these recorded data, it is aimed to design solar energy measurement systems and enable the realization of new models. In addition, it is an important value of our study that the developed model can be used in regions with similar climate and conditions and can guide people who will do research on this subject.
