Development of a MATLAB Graphical User Interface for Predicting Bifacial Photovoltaic Panel Output

The growing global demand for renewable energy highlights the importance of photovoltaic (PV) technology as a sustainable energy solution. Unlike traditional monofacial modules, bifacial PV panels are designed to capture sunlight on both their front and rear surfaces, resulting in improved efficiency. However, accurately predicting the energy output of these panels remains a challenge due to the influence of environmental factors. PV panels are capable of delivering power up to their rated capacity only under Standard Test Conditions (STC), but deviations in weather conditions often cause their performance to fall below the rated output. Therefore, accurate predictions must consider variables such as weather fluctuations, peak sun hours, and temperature, all of which have a significant impact on their performance. This study focuses on development of a Graphical User Interface (GUI) MATLAB Appdesigner to perform the prediction of Bifacial PV modules power output. The results have shown that the GUI can predict the power output of the Bifacial PV panel of 213 Watt.
