In this work,bisection (BM) and secant (SM) Methods currently exists to demonstrate the non-linearelectrical behavior of this device. The proposed method is tested in order to solve non-linearequation of PV cell with various values of load resistance are characterized. Comparisonsbetween these numerical examples have been compared. The main idea of the present workis to calculate the PV parameters numerically using different methods with the comparisonbetween them. The results showed that secant method is the best because it has leastiteration to obtain the optimal values of the PV parameters.
