这项工作的目的是评估一种简单的分析方法，用于提取光伏组件行为方程中涉及的参数。根据在不同温度和辐照度条件下获得的一系列实验电压-强度曲线，通过数值提取模型参数，使得数据点（短路电流、开路电压和最大功率点电压）和整个曲线的调整误差小于1%。还证实，为串联和并联电阻分配合适的值可以避免必须事先知道特性曲线的斜率值，而太阳能电池组件规格中通常不会标明该斜率值；即使理论参数适应其他温度和辐照度条件，这也会在实验曲线和理论模型之间产生良好的调整结果。 (C) 2001 Elsevier Science Ltd. 保留所有权利。
The aim of this work is to evaluate a simple analytical method for extracting parameters involved in the photovoltaic module behaviour equation. Based on a series of experimental voltage-intensity curves obtained under various temperature and irradiance conditions, values are obtained to extract the model parameters, giving rise to adjustment errors at data points (short circuit current, open circuit voltage and voltage at maximum power point) and in the entire curve that are less than 1%. It has also been confirmed that assigning suitable values for series and parallel resistance avoids having to know beforehand the slope value of the characteristic curve, which is not normally indicated in the solar module specifications; this gives rise to good adjustment results between the experimental curves and the theoretical model, even when the theoretical parameters are adapted to other temperature and irradiance conditions.
