光伏（PV）设备的建模是今天使用的一些活动，如系统监测，功率预测，故障诊断等明确的经验模型的基础上的的参数是很容易实现的计算机辅助计算，因此，他们允许快速评估的电气行为，无论是测试条件（稳态，瞬态等）。本文重点介绍了一个校正因子，这些模型之一，以提高其性能的工作点不同于最大功率点（MPP）。电流-电压（I-V）特性的比较由前者和建议的模型预测清楚地表明了建议的校正因子的有效性。该模型进行了测试，为不同的环境条件和不同的材料构成的PV电池。
Modelling of PhotoVoltaic (PV) devices is today used for a number of activities such as systems monitoring, power forecasting, fault diagnosis, etc. Explicit empirical models based on the datasheet parameters are quite easy to implement in computer-aided calculations and therefore they allow fast evaluations of the electrical behavior, whatever is the test condition (steady-state, transient, etc.). This paper focus on the introduction of a correction factor for one of these models in order to improve its performance for operating points different than maximum power point (MPP). The comparison between the current-voltage (I-V) characteristics predicted by the former and the proposed models clearly shows the effectiveness of the proposed correction factors. The model is tested for different environment conditions and for different materials constituting the PV cells.
