A complete modeling and analysis of solar system (cell/module/array) based on MATLAB

Abstract

The instalment of photovoltaic power supply to the grid is necessary with a great pace due to scarcity of fossil fuel. The efficiency and cost of the photovoltaic system can be obtained by operating the PV array at the maximum of the PV system. Computer modeling has become important to estimate performance parameters, characteristics and electrical behaviour of a complete PV system (cell, module, array using MATLAB). This work presents computer modeling of a complete PV system. The effects of irradiance, temperature, shading and bypass diode on the output parameter [current, power, maximum power] are considered in this paper. The single diode model with series and parallel resistor is used to model the PV cell. Then the single cell is used to modeling and simulation of PV module and array. A typical 1KW solar panel is used for model evaluation. The developed computer model can be used to predict the behaviour of PV cell, module and array under different environmental and physical parameter. The proposed model can simulate the performance of commercial PV based power system and help to develop control system for driving the load of solar system in maximum power.
