Developing a New I‐V Translation Methodology in Accordance With IEC 60891:2021 Correction Procedure 1 and 2

Accurate translation of photovoltaic (PV) module I‐V curves under varying operating conditions is essential for evaluating module performance and ensuring reliable energy output predictions. This study proposes a hybrid correction procedure (HCP) for I‐V curves, utilizing a four‐parameter Gompertz model to integrate the strengths of CP1 and CP2, thereby unifying the two approaches into a cohesive framework. It further evaluates the performance of HCP alongside existing correction methods (CP1 and CP2) across a broad range of irradiance ( G ) and module temperature ( T m ) conditions. CP1 demonstrates the highest accuracy in P MAX correction, with RMSE values consistently below 0.50% for most modules, but fails to generate complete I‐V curves when translating from low to high‐irradiance levels. CP2, while achieving superior accuracy in V OC correction, struggles with low‐ R sh modules, leading to distorted I‐V curves and reduced accuracy in P MAX and I SC . The proposed HCP method successfully integrates the strengths of CP1 and CP2. It achieves I SC results comparable to CP1, V OC results similar to CP2, and significantly lower RMSE in P MAX compared to CP2, particularly under challenging low‐ R sh and high‐ R S conditions. These findings validate the effectiveness of HCP as a robust alternative correction method for improving the accuracy of I‐V curve translations under diverse real‐world operating conditions. This work provides a pathway to more accurate PV module performance analysis and highlights the importance of addressing R sh and R S effects in future correction procedures.
