Performance assessment of a bifacial PV system using a new energy estimation model

Abstract

This study presents a comprehensive performance assessment of a bifacial photovoltaic (PV) system and real-time validation of a new energy estimation model. The system consists of 18 bifacial PV modules installed at a test site with a total capacity of 6.8 kWp. The system’s performance was evaluated based on its energy yield over one year. The energy estimation model was validated in real-time using data collected from the bifacial PV system. The results show that the bifacial PV system achieved an annual energy yield of 1569 kWh/kWp. The energy estimation model was accurate and reliable, with correlation coefficients of 1.04 and 1.40 for the front and rear sides, respectively. This study provides valuable insights into the performance of bifacial PV systems and the development of precise energy estimation models, which can help design and optimize PV systems in different environmental conditions.
