Abstract
In the work, a dynamic model is proposed in Simulink, to model the behavior of photovoltaic modules and arrays. A novel methodology is proposed to obtain exactly the five parameters of the simple diode model, through the data provided by the manufacturer in the data sheet. The model proposes the calculation of the Volt-Ampere curve from environmental conditions, solar irradiance, ambient temperature and second-order effects, such as: the influence of temperature on the photocurrent generated and on the open circuit voltage, as well as the spectral and optical effects. The validity and accuracy of the proposed model is checked by comparing its results, with curves and experimental data from the manufacturer's data sheet. In addition, curves of the module are shown, allowing to evaluate its behavior taking in to account the optical and spectral effects.
