An improved simulation model for photovoltaic cell

The photovoltaic (PV) system design of a balance of system includes design of a solar module, a battery, an inverter and a charge controller. The study of electrical response of a solar module is important, since it decides the key design parameters. This paper presents an overview and comparative study of electrical response of few existing PV models. A more reliable and accurate model for predicting the PV module output is developed using MATLAB which compensate the temperature effect on series and parallel resistance of the cell. An experiment was carried out to obtain the current voltage (I-V) characteristics for a particular typical 3W module. All simulation results are compared to experimental results. The simulation result of the proposed model shows good match with the experimental results.
