摘要

通过光伏效应，光伏电池将太阳能转化为电能。光伏电池是串联的，以达到所需的电压(约700-1000V DC)，然后并联，以获得更大的电流(8- 16a)。光伏电池必须在其最大功率点使用。光伏板的I - U曲线是非线性的，温度或太阳辐照等环境因素会对最大功率点的特性和位置带来较大的变化。本文提出了一种基于二极管数学模型的方法，在不同气象条件下，仅利用厂家提供的数据跟踪光伏板或光伏场的最大功率点。该模型已经用商用光伏组件CHSM6610P Astroenergy的实验数据进行了验证。

Modeling of Photovoltaic Panels

Through the photovoltaic effect, photovoltaic cells convert solar energy into electrical energy. Photovoltaic cells are connected in series to reach the desired voltage (around 700-1000V DC), then parallel in order to obtain a higher current (8-16 A). The photovoltaic cells must be used at their maximum power point. The I – U curve of a photovoltaic panel is non-linear, and environmental factors such as temperature or solar irradiation bring considerable variations to the characteristic and location of the maximum power point. This paper presents a method based on the mathematical model of a diode for tracking the maximum power point of a photovoltaic panel or a photovoltaic field under different meteorological conditions using only the data provided by the manufacturers. The model has been validated with experimental data of a commercial photovoltaic module, CHSM6610P Astroenergy.
