Abstract
Photovoltaic (PV) systems are increasingly deployed to meet the growing demand for clean, cost-effective energy while supporting grid stability. However, partial shading of PV modules can significantly degrade system performance by reducing energy yield. This paper presents a systematic evaluation of partial shading effects on state-of-the-art half-cut monocrystalline silicon PV systems, with a comparative analysis of monofacial and bifacial module configurations under well-defined shading scenarios. The results indicate that bifacial PV systems achieve a higher annual energy yield, with an average gain of 6.3 % compared to monofacial systems across a wide range of shading scenarios. This improvement is primarily attributed to the utilization of rear-side irradiance reflected from surrounding surfaces. In contrast, monofacial modules consistently exhibit higher performance ratios (PR), largely due to the conventional definition of PR and its dependence on front-side irradiance. Overall, both technologies demonstrate enhanced shading resilience due to half-cut module structures.
