This paper presents a detailed eplaination about various characteristics of ideal single diode, practical single diode and two diode equivalent circuit models realized for modeling of solar photovoltaic cell.Then it presents non-linear mathematical equations necessary for producing I-V and P-V characteristics from a single diode model.A flowchart has been made for estimation of solar cell output current, for single diode and two diode model, using Newton-Raphson iterative technique which is then programmed in MATLAB script file accordingly.A typical 120W polycrystalline solar module specifications have been used for model accuracy evaluation.The characteristic curves were obtained with the use of manufacturer`s datasheet and it shows the precise correspondence to both the models.
