Solar photovoltaic technology is a major contender in the race for renewable, sustainable and green energy. This paper introduces the characteristics of different PV cell equivalent circuit and its output behaviour. It describes and implements the proposed characterization method by using a selected model. It generates I-V and P-V curve using iterative method. Noise analysis and observation of curve fitting are briefly described here. The white noise effect and its related output characteristics are explained too. To introduce and implement the generalized method, a photovoltaic electrical equivalent circuit is used here. The fundamental equation of a PV cell is used to study the model and to analyze the best fit of observed data. The values of ideal parameters are used to study the model’s behaviour. The main objective is to measure the noise in data approximation and on the polynomial curve fitting method for both the I-V and P-V curve.
