The photovoltaic (PV) model allows the current–voltage characteristic curves of the PV module to be represented in the simulation, which is important in the development of the PV generation system. Nevertheless, the current single PV model is not able to receive multiple irradiance and temperature input to simulate the partial shading condition. The conventional PV model with the partial shading capability requires several PV models that are connected with a bypass diode in parallel to each PV model. As a result, the computation time becomes high and the adaptability of this model is low since it requires a circuit simulation software. This paper presents an adjuster that allows a standard PV model to have partial shading capability. The proposed PV model is only applicable for the series configuration only. The single diode model with a series resistance is used to design the PV model in MATLAB/Simulink and the results have been compared and analysed with the conventional PV model. From the results, it has shown that the proposed PV model is able to be executed up to 46 times faster in computation time compared to the conventional PV model while maintaining the maximum power point error below 4%.

光伏（PV）模型允许在仿真中表示光伏模块的电流-电压特性曲线，这对于光伏发电系统的开发非常重要。但是，当前的单个PV模型无法接收多个辐照度和温度输入来模拟部分阴影条件。具有部分遮蔽能力的常规PV模型需要几个PV模型，这些PV模型与一个旁路二极管并联，并与每个PV模型并联。结果，由于需要电路仿真软件，因此计算时间变长并且该模型的适应性低。本文介绍了一种调节器，该调节器允许标准PV模型具有部分阴影功能。建议的PV模型仅适用于串联配置。在MATLAB / Simulink中，使用具有串联电阻的单二极管模型设计PV模型，并与常规PV模型进行了比较和分析。从结果可以看出，与传统的PV模型相比，所提出的PV模型在计算时间上的执行速度最高可提高46倍，同时最大功率点误差保持在4％以下。
