A new method for extracting five parameters of single diode is presented in this paper. Through the further derivation and simplification of the formula, five parameters under a single condition can be obtained analytically by using only three key operating points (open circuit voltage point (OC), short circuit current point (SC), maximum power point (MPP)) and datasheet values, which can achieve high accuracy in only two iterations. The accuracy and effectiveness of proposed method have been validated by experimental data under different environmental conditions.
