A simulation model based on circuits for a photovoltaic cell to estimate the characteristic curves IV of the photovoltaic panel with respect to changes in environmental parameters (temperature and irradiance) and cellular parameters (parasitic resistance and ideality). ). Using a Shockley diode equation, a precise FV simulator panel model is developed. The Solarex MSX60 60W solar panel is chosen to evaluate the developed model.
A simulation model based on circuits for a photovoltaic cell to estimate the characteristic curves IV of the photovoltaic panel with respect to changes in environmental parameters (temperature and irradiance) and cellular parameters (parasitic resistance and ideality). Development of the MPPT (power power tracking) algorithm. Using a Shockley diode equation, a precise FV simulator panel model is developed. The Solarex MSX60 60W solar panel is chosen to evaluate the developed model. Index of photovoltaic (PV) terms, Shockley diode, irradiance, Matlab / Simulink, IV and PV curves and MPPT.
The number of unknown parameters increases when the equivalent circuit of the chosen model is more convenient and far from ideal. But most manufacturers' data sheets do not give enough information on parameters that depend on weather conditions (irradiance and temperature). Therefore, some assumptions regarding the physical nature of cellular behavior are necessary to establish a mathematical model of the photovoltaic cell and the photovoltaic module, in addition, of course, to the use of that information given by the constructors. The objective of this work is to present a useful work to those who want to focus their attention on the photovoltaic module or matrix as a device in a complex electroenergetic system. Therefore, the objective is to obtain at any time, the maximum power, but also the most accurate, therefore, the closest to the experimental value.
