| contents | Accurate performance modeling of PV systems in urban environments is a significant challenge due to complex partial shading. This study introduces a high-resolution, hierarchical modeling framework that provides detailed insights from the solar cell to the system level. Rigorously validated against field-test data from calibrated equipment, the model demonstrates high accuracy in predicting minute-wised dynamic electrical characteristics (R2 > 0.90). A key finding is the critical shortcoming of conventional, coarser-resolution models under realistic shading; these are shown to overestimate the actual string operating power by up to 163% and the monthly energy yield by up to 54%. The proposed framework avoids these errors by precisely capturing mismatch losses and the time-varying phenomena of system components, such as bypass diode activations. Furthermore, the model accurately quantifies the effectiveness of mitigation technologies, showing that Module-Level Power Electronics (MLPEs) can increase the monthly energy yield of a heavily shaded string by over 20%. This research provides a crucial tool for reliable system design, accurate power forecasting, and the optimization of PV systems in complex urban settings. |
